Further, in the punching tool 1 of the first embodiment described above, a first surface 8 for pushing the male mold 2 is formed on the surface of the pushing body 4 on the opposite side of the intermediate body 6. Further, a second surface 9 is formed on the surface of the receiver 7 on the opposite side of the intermediate body 6. Then, the punching tool 1 described above has a first punching posture in which the punched material S is punched by pushing the first surface 8 above the second surface 9 downward and the first surface. It has a second punching posture in which the punched material S is punched by pushing the second surface 9 on the upper side with the 8 facing down. These first punching postures and second punching postures can be selected by turning the punching tool 1 upside down. After that, the punching posture of the first embodiment in which the first punching posture is selected is selected. Taking the punching tool 1 as an example, the pushing body 4, the male type 2, the intermediate body 6, the female type 5, and the receiving body 7 constituting the punching tool 1 will be described.

As shown in FIGS. 1 to 5, the pushing body 4 is a member having a male mold 2 for punching the punched material S so as to be able to move back and forth. The pushing body 4 is connected to the intermediate body 6 via a first swinging shaft 10 described later, and is intermediate by swinging upward around the axis of the first swinging shaft 10 facing in the left-right direction. It is possible to move away from the body 6 or to approach the intermediate body 6 by swinging downward. Further, the pushing body 4 has a pushing base portion 11 that freely supports the male mold 2 described above in the vertical direction. A pushing member 12 for the user to push the male mold 2 downward is attached to the upper end of the male mold 2.

The male mold 2 described above is a member formed in a rod shape elongated in the vertical direction, and a punching blade 3 is formed in the lower portion thereof, so that the punched material S can be punched out. Specifically, the male mold 2 has a flange portion 13 formed horizontally extending outward toward the middle side in the vertical direction, and has different functions on the upper side and the lower side of the flange portion 13. The flange portion 13 is formed in a square flat plate shape corresponding to the substantially square box-shaped pushing base portion 11 described later. In the present embodiment, since the pushing base portion 11 has a substantially square box shape, the flange portion 13 is formed in a square flat plate shape. However, when the pushing base portion 11 is a substantially round cylinder or a columnar shape, the flange portion 13 is formed. Can also be formed in the shape of a round plate.

The portion 2a above the flange portion 13 in the male mold 2 is a press button 14. The press button 14 is formed in a columnar shape protruding upward, and its upper surface is formed in a flat surface shape so that the user can easily push it. The press button 14 is exposed upward so that the user can press it, and a member such as the push member 12 described above can be fitted externally from above. It may be used as. In the present embodiment, the one used as the protrusion for externally fitting the push member 12 will be illustrated and described.

On the other hand, a punching blade 3 projecting downward is formed in a portion 2b below the flange portion 13 of the male mold 2. The punching blade 3 has a shape sharpened downward, and in the present embodiment, the punched material S can be punched by pushing it downward. Further, the cross section of the punching blade 3 along the horizontal direction has a shape corresponding to the shape to be punched, and in the case of this embodiment, it has a substantially pentagonal star shape (here, each vertex of the pentagram). On the other hand, it means a shape formed by connecting adjacent vertices with arcuate sides bent toward the center side, and does not mean a so-called pentagram or a star-shaped pentagram. It has the same shape as in the book).

Further, the cross section of the punching blade 3 along the horizontal direction has a smaller cross-sectional area than the pushing member 12 described later, and the force applied to the pushing member 12 can be amplified to perform punching. There is. For example, the punching blade 3 of the present embodiment has a cross-sectional area of about 1/10 of that of the pushing member 12, and the punching material S is reliably secured by a force of about 10 times the force applied to the pushing member 12. It is possible to punch out.

Further, the punching blade 3 is formed in a curved surface shape that is hemispherically cut upward, and the cutting edge formed on the outer edge of the punching blade 3 is sharpened downward. It has become. By adopting such a blade shape, it is possible to reliably cut (punch) the punched material S with the female mold 5.
The pushing member 12 is a flat plate-shaped member formed to be wider in the horizontal direction than the pushing base portion 11 described later, and has a flat upper surface formed so as to be easily pushed downward. Further, on the lower side of the pushing member 12, a neck portion 15 extending downward is formed. The neck portion 15 is formed in a square tubular shape having a substantially quadrangular cross section, and an insertion portion 16 capable of inserting the above-mentioned press button 14 (upper end of the male mold 2) is formed on the lower side thereof. The insertion portion 16 is formed in a square hole shape, and the pushing member 12 is fitted (outerly fitted) to the press button 14 of the male portion formed in a columnar shape from above to move the pushing member 12 to the upper side of the male mold 2. It can be connected and fixed.

In this embodiment, an example is given in which the neck portion 15 is formed in a square tubular shape having a substantially square cross section and the insertion portion 16 is formed in a square hole shape. However, the neck portion 15 may be formed in a cylindrical shape having an annular cross section, or when the neck portion 15 is formed in a cylindrical shape, the insertion portion 16 may be formed in a round hole shape. Further, the press button 14 fitted into the neck portion 15 may be formed in a square tubular shape.

Further, the upper surface of the pushing member 12 is formed in a flat surface shape, so that the user can easily push the male mold 2 downward by using the palm or the pad of a finger. That is, the upper surface of the pushing member 12 is formed on the opposite side to the lower side on which the intermediate body 6 is provided, and constitutes the first surface 8 on which the user pushes the male mold 2 downward. The upper surface of the pushing member 12 may be formed as a curved surface that is curved so as to gently rise upward. Such a curved pushing member 12 is easy to fit in the palm of the user and is easy to operate even when pushing.

The pushing base 11 is a hollow member (case member) having a substantially square box shape (covered square cylinder shape) in appearance, and is open to both the upper side and the lower side. Inside the push base portion 11, a cavity having a substantially quadrangular cross section cut in the horizontal direction is formed, and the male mold 2 described above is housed in this cavity. Specifically, the male mold 2 is made movable in the vertical direction while being housed inside the pushing base portion 11 by bringing the outer edge of the flange portion 13 into surface contact with the inner peripheral surface of the pushing base portion 11. There is. Further, on the inner peripheral surface of the pushing base portion 11, guide ribs (not shown) projecting toward the center of the pushing base portion 11 are formed along the vertical direction. Further, a guide groove (not shown) that fits with the guide rib described above is formed on the outer peripheral edge of the flange portion 13 of the male mold 2 described above, and the pushing base portion 11 is formed in the guide groove of the flange portion 13 described above. By fitting (floating) the guide ribs of the above, the male mold 2 can be guided in the vertical direction with respect to the pushing base portion 11.

In the above-mentioned example, a guide rib is provided on the inner peripheral surface of the pushing base portion 11, and a guide groove is provided on the outer peripheral edge of the flange portion 13. However, the guide rib may be provided on the outer peripheral edge of the flange portion 13 and the guide groove may be provided on the inner peripheral surface of the pushing base portion 11. Further, guide ribs may be provided on the inner peripheral surface of the pushing base portion 11 and the outer peripheral edge of the flange portion 13 in a protruding shape, and the guide ribs may be brought into contact with each other and slid to guide the flange portion 13.

The opening 11a on the upper side of the pushing base 11 has a quadrangular open top view. The opening size of the upper opening 11a is slightly larger than that of the neck 15 of the push member 12, and the neck 15 and the insertion portion 16 of the push member 12 connected to the neck 15 move in the vertical direction. Is acceptable.
Further, the lower opening 11b of the pushing base 11 has a quadrangular top view similar to the upper opening 11a. In the present embodiment, the lower opening 11b is also opened in a quadrangular shape corresponding to the square tubular pushing base portion 11, but when the pushing base portion 11 is cylindrical, the lower opening is opened. The portion 11b also opens in a circular shape. The lower opening 11b is opened with a larger opening area than the upper opening 11a, and the central side of the opening is closed by the base closing member 19. Specifically, the base closing member 19 has a substantially disk-shaped lower closing member 19b having a diameter slightly larger than that of the lower opening 11b of the pushing base 11, and a diameter larger than that of the lower closing member 19b. It is formed in a shape (stepped disk shape) in which a disk-shaped upper closing member 19a having a small diameter is vertically superposed. The lower closing member 19b can partially close most of the lower opening 11b except for the four corners by fitting the outer peripheral side to the lower opening 11b of the pushing base portion 11.

On the other hand, the upper surface of the upper closing member 19a is formed in a flat surface shape, and an elastic member 20 described later can be arranged between the flat upper surface and the lower surface of the flange portion 13. A through hole 21 is formed in the center of the base closing member 19 so as to communicate the upper closing member 19a and the lower closing member 19b in the vertical direction, and the through hole 21 is more than the flange portion 13. The lower male mold 2b is slidably inserted in the vertical direction.

On the lower side of the base closing member 19 (lower member), a pressing body 22 that exerts a downward pressing force on the punched material S toward the intermediate body 6 side (lower side) is provided. An elastic material such as rubber or elastomer is used for the pressing body 22, and the pressing body 22 is formed of the elastic material into an annular shape (although it is annular in the present embodiment, it may be in the shape of a square frame or the like). There is. If such a pressing body 22 made of an elastic material is provided, the punched material S can be strongly pressed toward the intermediate body 6 by the amount of the elastic force of the elastic material applied, and rubber, an elastomer, or the like can be pressed. Since it exerts a non-slip function, the punched material S can be reliably held between the pushing body 4 and the intermediate body 6 so as not to move, and the punched material S is inside the female mold 5. It is possible to prevent the occurrence of problems such as getting in or wrapping around the male mold 2 (problems caused by loose pressing).

In the elastic member 20 described above, when the male mold 2 and the pushing base portion 11 are in the positions shown in FIG. 2, in other words, when the male mold 2 is in a position completely retracted into the pushing base portion 11. , Has a spring that makes the urging force zero (neutral). That is, as shown in FIG. 2, when the male mold 2 is completely retracted into the pushing base portion 11, no load is applied to the elastic member 20 and no urging force is generated. However, if the lower end (punching blade 3) of the male mold 2 protrudes downward from the pushing base portion 11 even a little, a load is applied to the elastic member 20 in the degenerate direction (an urging force is generated). That is, when punching the punched material S, punching is possible by pushing the pushing member 12 (male type 2) downward against the above-mentioned urging force. However, when the punching is completed and the force is released, the male mold 2 can be moved upward to the inside of the pushing base 11 by using the generated urging force, and the male mold 2 is automatically returned to the state before punching. It is possible to restore it.

Although an example using a spring is shown in the present embodiment, an elastic member other than the spring may be used as long as the elastic member 20 generates an urging force in the direction opposite to the pushing force.
The intermediate body 6 is a member provided on the lower side of the pushing body 4 described above, and is swingably connected around the first swinging shaft 10 facing the pushing body 4 in the horizontal direction (horizontal direction). , The punched material S can be sandwiched between the pushing body 4 and fixed. Further, in the center of the intermediate body 6, a female mold 5 into which a male mold 2 extruded from the pushing body 4 can be inserted is formed in a through hole shape penetrating the intermediate body 6 up and down.

In the present embodiment, the female mold 5 is formed in the center of the intermediate body 6 so as to correspond to the male mold 2. However, when the position of the male mold 2 is on the outer peripheral side, the position of the female mold 5 is formed. May be formed on the outer peripheral side of the intermediate body 6 corresponding to the male type 2.
The female mold 5 is formed at a position corresponding to the position where the male mold 2 protrudes from the pushing base 11, and maintains a clearance that does not hinder the vertical movement of the male mold 2, while maintaining a clearance in the horizontal direction of the male mold 2. It is formed in the shape of a hole having a cross-sectional area slightly larger than the cross section of the above, and the punched material S can be punched.

When a tape having adhesiveness or the like is used as the punching material S around the female mold 5, or more accurately around the female mold 5 in the intermediate body 6, the punched material S is in an adhesive state. A holding surface 26 that can be held may be formed. The holding surface 26 is formed of a material such as POM resin (polyoxymethylene resin), which has excellent mechanical strength and wear resistance, but can realize a surface texture to which an adhesive is difficult to adhere. Surface can be used.

Further, the above-mentioned intermediate body 6 and the pushing body 4 are connected by the first connecting means 27 so that they can be brought into contact with each other. Specifically, the first connecting means 27 includes a first connecting piece 28 provided on the rear side of the pushing base 11 of the pushing body 4 and a second connecting piece 29 provided on the rear side of the intermediate 6. And a first swinging shaft 10 that swingably connects the first connecting piece 28 and the second connecting piece 29.

The first connecting piece 28 has a substantially U-shape with the lateral view open upward, and is formed so as to project from the rear side to the rear side of the pushing base portion 11. In this embodiment, although a substantially U-shaped example is given, the first connecting piece 28 may be formed in an annular shape when viewed laterally.
Further, the second connecting piece 29 has a substantially U-shape with the side view open downward, and is formed so as to project from the rear side of the intermediate body 6 toward the rear upper side.

Further, the first swing shaft 10 communicates in the left-right direction between the center of the first connecting piece 28 formed in a substantially U shape and the center of the second connecting piece 29 also formed in a substantially U shape. It is a shaft member arranged so as to do so. By the first swinging shaft 10, the above-mentioned first connecting piece 28 and the second connecting piece 29 are swingably connected around an axis facing the left-right direction.
A third connecting piece 30 is also formed on the rear side of the intermediate body 6. The third connecting piece 30 is one of the members constituting the second connecting means 31 that connects the intermediate body 6 and the pushing body 4 so as to be detachable from each other, and is from the rear side to the rear side of the intermediate body 6. It is formed so as to protrude downward. Further, the third connecting piece 30 has a structure in which the second connecting piece 29 is turned upside down, and is formed in a substantially U shape with the lateral view open upward.

On the other hand, under the intermediate body 6 described above, a receiver 7 for receiving the punched material S punched between the male mold 2 and the female mold 5 described above is provided. The receiver 7 is a plate-shaped member having the same dimensions as the pushing body 4 described above in the front-rear direction and the left-right direction, and the punched material S described above can be temporarily fixed to the center of the upper surface. The portion 32 is formed.
The temporary fixing portion 32 is a member that bulges upward in a hemispherical shape, and the center of the temporary fixing portion 32 bulges upward from the periphery. The upper end of this upwardly bulging portion is formed in an area smaller than the cross section of the punching blade 3 (area of the punched material S), and when a punched material S or the like having an adhesive surface is used. By partially adhering to the adhesive surface of the punched material S, the punched material S can be easily peeled off from the temporary fixing portion 32.

Further, on the lower surface of the receiver 7, a flat second surface 9 is formed on the opposite side of the upper side where the intermediate body 6 is provided, as in the case of the first surface 8 described above, and the second surface 9 is formed on the lower surface. The punching tool 1 can be placed on a floor surface or the like so as to be in contact with each other.
On the rear side of the above-mentioned receiver 7, a fourth connecting piece 33 constituting the second connecting means 31 is provided together with the above-mentioned third connecting piece 30.

Specifically, the second connecting means 31 includes a third connecting piece 30 provided on the rear side of the intermediate body 6 described above, a fourth connecting piece 33 provided on the rear side of the receiver 7, and a third connecting piece 33. It is composed of a second swinging shaft 34 that swingably connects the connecting piece 30 and the fourth connecting piece 33.
The fourth connecting piece 33 described above has a substantially U-shape with the lateral view open downward, and is formed so as to project from the rear side of the receiver 7 toward the rear side.

Further, the second swing shaft 34 communicates in the left-right direction between the center of the third connecting piece 30 formed in a substantially U shape and the center of the fourth connecting piece 33 also formed in a substantially U shape. It is a shaft member arranged so as to do so. By the second swinging shaft 34, the above-mentioned third connecting piece 30 and the fourth connecting piece 33 are swingably connected around an axis facing the left-right direction.
That is, by using the above-mentioned first connecting means 27 and the second connecting means 31 in combination, in the punching tool 1 of the present embodiment, the pushing body 4, the intermediate body 6, and the receiving body 7 can be brought into contact with each other freely. They are connected to each other so as to be.

By the way, as described above, when the punching tool 1 of the present embodiment is installed so that the receiver 7, the intermediate body 6, and the pushing body 4 are arranged in order from the lower side, the punching tool 1 is the lowermost side. The punching tool 1 can be placed on the floor surface or the like in a stable posture in a state where the second surface 9 (lower surface) of the receiver 7 located in the above is in contact with the floor surface or the like in a surface state. Further, in this posture, the first surface 8 of the pushing member 12 of the pushing body 4 located on the uppermost side faces upward, so that if the first surface 8 is pushed downward, the punched material S can be used. Punching is possible. That is, the posture shown in FIGS. 1 to 5 described above is a "first punching posture" in which the punched material S is punched by pushing the first surface 8 above with the second surface 9 facing down. Is nothing but.

As shown in FIG. 5, when punching is performed in the first punching posture, the punching tool 1 is first rotated between the pushing body 4 and the intermediate body 6 to charge the punched material S. .. That is, as shown in the upper left of FIG. 5, the pushing body 4 and the intermediate body 6 are connected by the first connecting means 27, and swing around the axis of the first swing shaft 10 facing in the left-right direction. It is free. Therefore, the punching tool 1 can be opened between the pushing body 4 and the intermediate body 6 at an arbitrary angle (90 degrees in the illustrated example) about the first swinging shaft 10, and the pushing body 4 can be opened by swinging. And the intermediate body 6 are separated from each other, and the punched material S can be charged between the pushing body 4 and the intermediate body 6 from the space created by the separation.

When the punched material S is charged between the pushing body 4 and the intermediate body 6 in this way, the pushing body 4 and the intermediate body 6 that have been opened by swinging are returned to their original states. That is, the pushing body 4 and the intermediate body 6 are arranged so that the receiving body 7, the intermediate body 6, and the pushing body 4 are lined up in order from the lower side, and are returned to the state before separation. Then, the pushing member 12 is pushed downward.
Then, a downward force is applied to the male portion 2 in which the press button 14 is inserted into the insertion portion 16 of the pushing member 12, and the male mold 2 moves downward inside the pushing base portion 11. The male mold 2 moves downward in a state where the guide rib on the inner peripheral surface of the pushing base portion 11 is fitted into the guide groove of the flange portion 13 (free fitting state). Further, the male mold 2 moves downward while being fitted in the through hole 21 formed in the center of the base closing member 19. Therefore, the male mold 2 moves linearly from the pushing base 11 so as to project downward without changing the position in the left-right direction or the front-back direction.

Further, if the pushing body 4 and the intermediate body 6 are aligned (positioned) by the positioning means 23 described later, the male mold 2 does not shift from the female mold 5. Therefore, the male mold 2 protruding downward from the pushing base 11 makes it possible to reliably punch the punched material S placed on the surface of the female mold 5 of the intermediate body 6.
The punched material S punched into a desired shape (star shape in the case of the present embodiment) by the male mold 2 in this way is adhered to the temporary fixing portion 32 that bulges upward of the receiver 7. , It does not return to the female mold 5 while sticking to the punching blade 3.

Therefore, in the punching tool 1 in the first punching posture, it is possible to reliably punch a desired shape from the tape-shaped punched material S.
By the way, the punching tool 1 of the first embodiment described above can adopt not only the first punching posture but also the second punching posture. In this second punching posture, the punching material S is punched by pushing the upper second surface 9 downward with the first surface 8 facing down, and the punching tool 1 is "up and down". By "reversing", it is possible to change the posture from the first punching posture to the second punching posture. Next, the second punching posture will be described.

The second punching posture described above is a posture in which the receiver 7, the intermediate body 6, and the pushing body 4 are installed so as to be arranged along the upper and lower sides in order from the upper side, and the first pushing member 12 located at the lowermost side. The surface 8 comes into contact with the floor surface or the like in a surface state, and the punching tool 1 can be placed on the floor surface or the like in a stable posture. Further, in this second punching posture, the second surface 9 of the receiver 7 located on the uppermost side faces upward, so if the second surface 9 is pushed downward, the male type 2 will react. The punching material S can be punched by protruding upward from the pushing base portion 11. That is, the posture shown in FIGS. 6 to 9 described above is a "second punching posture" in which the punched material S is punched by pushing the second surface 9 above with the first surface 8 facing down. Is nothing but.

As shown in FIG. 8 and the like, in the second punching posture, a part of the punched material S is visible through the female mold 5 formed in a hole shape, so that the male mold 2 and the female mold 5 are visible. The punched material S can be reliably aligned with the position of.
For example, when a specific mark or the like is printed on the punched material S, if it is desired to accurately align the printed mark with the punched shape and punch it, the punched material S is used in the first punching posture. May get in the way and you may not be able to align. However, in the second punching posture, the punched material S can be visually recognized through the hole of the female mold 5 of the intermediate body 6, so that the punched material is located at the position of the male mold 2 or the female mold 5. The S can be reliably aligned, and the punched material S can be punched out with a good finish.

If at least one of the pushing body, the intermediate body, and the receiving body is formed of a transparent body, the punched material S can be visually confirmed through these members of the transparent body. Can be punched out with a good finish.
[Second Embodiment]
Next, the punching tool 1 of the second embodiment will be described.

As shown in FIGS. 10 to 12, the punching tool 1 of the second embodiment is provided with a lever member 37 that pushes the first surface 8 downward on the upper side of the first surface 8. ing.
Specifically, the punching tool 1 of the second embodiment is also provided with the pushing member 12 as in the first embodiment, but the pushing member 12 does not have a large area as much as the first embodiment and has a plate shape. not. That is, the pushing member 12 of the second embodiment is formed in a cylindrical shape having a small cross section such that a part of the center of the pushing base portion 11 projects upward.

The lever member 37 described above is swingably connected to the upper surface of the pushing base portion 11 in the vicinity of the upper opening 11a. Specifically, the lever member 37 is a plate-shaped member that is long in the front-rear direction, and is connected to the upper surface of the pushing base portion 11 so as to swing around an axis whose rear end side faces the left-right direction.
Further, between the lever member 37 and the pushing base portion 11, a spring member (not shown) that pushes the lever member 37 toward the pushing member 12 side to generate an urging force is provided, and the lever member 37 is always used. It is urged so that it is pressed against the pushing member 12.

Further, the lever member 37 described above has a push-in protrusion 35 that curves downward on the lower surface on the intermediate side in the front-rear direction. The push-in protrusion 35 is a portion that bulges so as to be gently curved downward, and can come into contact with the upper surface of the push member 12. Therefore, when the front end side of the lever member 37 is swung around the rear end side, the pushing projection 35 of the lever member 37 pushes the pushing member 12 downward, and the male mold 2 is pushed below the pushing body 4. It is possible to shoot the punched material S into a desired shape or cut it off so as to have a desired end face.

Furthermore, between the intermediate body 6 and the pushing body 4 described above, the position of the male mold 2 is accurately aligned with respect to the female mold 5 in both the front-rear direction and the left-right direction. Alignment means 23 for matching the position of the mold 2 with the position of the female mold 5 is provided.
In the case of the present embodiment, the positioning means 23 projects upward toward the upper surface of the intermediate body 6 at a position away from the female mold 5 on the outer peripheral side, or more accurately, near the front corner of the intermediate body 6. It is composed of a guide post 24 formed in. Specifically, the pushing base portion 11 corresponding to the formation position of the guide post 24 is formed with a gap 25 that allows the guide post 24 to be inserted upward with the disc-shaped base closing member 19. By inserting the guide post 24 into the gap 25, the position of the male mold 2 and the position of the female mold 5 can be accurately aligned.

Further, in the punching tool 1 of the second embodiment, the receiver 7 is formed in a plate shape which is longer in the front-rear direction than that of the first embodiment. That is, since the second surface 9 of the receiver 7 of the second embodiment is formed in a large area, even if a large force is applied to the male mold 2 via the lever member 37 described above, the force is surely applied. It can be received and the punching posture does not wobble.
As described above, the punching tool 1 of the present invention can punch not only the tape-shaped punching material S but also the sheet-shaped punching material S. For example, as shown in FIG. 10, if the punched material S, which is wider in the vertical direction and the horizontal direction than the tape-shaped material, is sandwiched between the pushing base portion 11 and the intermediate body 6, the sheet-shaped punched material S is punched. It is possible to punch out a specific shape from the punched material S. Note that FIG. 10 shows the punching tool 1 of the same second embodiment as in FIGS. 11 and 12, but is shown as an example using the sheet-shaped punching material S, which is in the form of a tape. The structure of the punched material S is different from that of FIGS. 11 and 12 using the punched material S.

It should be noted that the embodiments disclosed this time are exemplary in all respects and are not considered to be restrictive. In particular, in the embodiments disclosed this time, matters not explicitly disclosed, such as punching conditions, various parameters, dimensions, weights, volumes, materials of components, etc., deviate from the scope normally practiced by those skilled in the art. It is not a thing, and a value that can be easily assumed by a person skilled in the art is adopted.

In the above-described embodiment, the upper surface of the receiver 7 is provided with a convex temporary fixing portion 32 that bulges upward. However, a temporary fixing portion 32 which is formed in a concave shape downward and penetrates in the vertical direction may be formed on the upper surface of the receiver 7. Such a concave temporary fixing portion 32 is formed in an opening area so that the punched material S does not fall downward, and the punched material S can be held so as to be scooped up from below.

Therefore, when the punched material S is taken out, the punched material S can be easily taken out from the temporary fixing portion 32 by pushing back the punched material S so as to flip up from the opening below the temporary fixing portion 32. This makes it possible to obtain a punching tool 1 having excellent convenience.
