Description

Multifunction bending device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal panel bending apparatus, and more particularly, to a multifunctional bending apparatus configured to perform shearing, bending, and forming in a single bending apparatus.

A device known as a paneling or bending machine is known as a device that cuts, bends and molds various shapes to produce flat metal panels in a desired profile.

The mechanisms are mainly divided into dies and punches as tools for producing products by shearing, bending, and forming materials by using materials such as plasticity, malleability, ductility, and fluidity. It is known that various processes such as shearing, bending, and beading are performed by mounting a panel on an upper die and pressing it with a punch for linear reciprocation.

The punch movement is mainly performed by vertical reciprocating movement, and the power is using a hydraulic cylinder according to the required performance.

The mechanisms are mainly divided into dedicated machines such as shearing machines, bending machines, molding machines, etc. according to their use.

According to the prior art, there is a problem that it is difficult to convert the shearing machine into a molding machine, so it is not compatible with each other, so it is manufactured as an independent dedicated facility.

In the production of dedicated equipment, various constraints such as economic burden and burden on equipment introduction space arise due to the problem of having to introduce each equipment in order to process the metal panel in a desired shape.

Look at the conventional bending machine.

As shown in FIG. 1, a conventional bending machine includes a die (D) and a punch (P). The die may be variously bent to obtain an optimal bending product in consideration of various factors such as material, thickness, and bending angle of the workpiece. It is made by grooving at an angle, and it is made to perform bending while replacing.

However, in the case of the conventional apparatus for performing bending while replacing the die and the punch, the replacement time due to the replacement of the die and the punch at each replacement time, the skill and the trouble of the replacement operator, is cumbersome.

There has also been proposed a compound die that improves the problem of reduced productivity due to the cumbersome die replacement and workability deterioration.

This is made of a complex type by varying the depth and angle of the V groove on the outer periphery of the four sides of the die, taking into account various operations depending on the thickness of the material to be processed. Although it has the advantage of eliminating the trouble of removing and re-installing, there is a problem that it is expensive to repair and reheating when the entire die needs to be replaced when wear occurs on a part of the lower die groove due to long use. .

On the other hand, there are known bending machines of the same type as published patent number 1988-23537 and published patent number 2014-40053.

It comprises a pair of bending blades, one top or one bottom, a fixed bending counter blade and an interactable blank holder.

The bending blade is preferably supported by a C-shaped function arm so that the C-shaped structure is movable vertically so that one or the other blade is attached to the edge of the metal plate to bend to form a band downward or upward. Are combined.

The counter blade is integrated into the base of the machine and places a metal plate for bending. The counter blade is a single piece and has a horizontal edge for pushing the metal plate as one of the bending blades is bent downward or upward.

The blank holder is used to hold the metal plate bonded to the counter blades during the bending operation so that the band will be straight and have a small radius of curvature. The operating edge of the blank holder above the edge of the counterblade is known to assist the blade used to bend down or upward the metal plate held tightly between the blank holder and the counterblade.

The bending machine having the C-shaped blade has the advantage that the bending direction can be continuously processed upward or downward while continuously conveying the panel, so that specific bending processing is quick and the lower die mold is excluded.

However, all of the above-mentioned patents fix the panel which is bent between the counter blade and the holder to bend in the C-shaped blade holder, and according to the bending form, the bending order cannot be performed due to mechanical interference between the panel and the bending blade. The problem is that there are many limitations of bending processing.

In addition, the C-type blade is configured to drive while rotating around the rotation axis has a disadvantage in that it is difficult to control the clearance or must be precisely controlled at a very high cost.

In addition, according to all the above-described prior art, it is a matter of course that various processing can not be achieved in a single installation device.

Therefore, there is a problem that a separate dedicated equipment for various processing must be equipped and move according to the processing stage to complete the work in the corresponding equipment.

The various processes may include shearing, bending, beading, which is one of molding operations, and the like.

Shearing is usually done by cutting a sheet with an equipment called a shearing machine. Considering the use of cutting dies and punches, the weight of dies and punches is heavy and dangerous to replace. Extremely rare. That is, the cutting edge and the bending process are provided by the respective dedicated machines, and thus there is a closed end.

The present invention is to solve the problems of the prior art as described above has the following problems.

The present invention is to provide a multi-functional bending device made to shear, bend, forming processing for a plate material to be folded in a single facility.

The present invention is to provide a multi-functional bending device made to bend at the required bending angle by transferring the bending position in the rotational motion while transmitting power to form a cutting or bending in a linear motion (Linear Motion).

The present invention is to provide a multi-functional bending device that can be made of a plurality of types of shearing, bending and forming process by forming a mold assembly consisting of selectively assembling a plurality of molds (punch) having a unique function individually.

The present invention is to make the bending angle range to be bent at a selected angle of the right angle, acute angle or obtuse angle and the rotational movement of the bending angle is supported by a computer numerical controller (CNC), without changing the die and punch It is to provide a multifunctional bending device that can bend the process.

The present invention made to solve the above problems is a counter blade fixed to the frame constituting the main body, a material holder for pressing and fixing the material during the bending operation, and to fix the panel to be folded by the counter blade and the material holder to the panel A mold assembly for bending or cutting by applying a linear processing force, a rotor assembly rotating the mold assembly around the counter blade to move to a variable position, and between the mold assembly and the rotor assembly, It includes a guider for guiding the linear movement of the assembly and transmitting the rotational force, and is made to be bent and cut linearly by bending, and to bend the mold assembly.

The mold assembly constituting the bending or deflection bending is coupled to both ends of the mold assembly to the rotatable assembly so as to be rotatable, so that the entire mold assembly is rotated and moved according to the up and down bending angles, and a straight line at the position where the inclination by the rotational movement is completed. The movement is implemented to achieve the machining of said different bending angles.

It is preferable that the rotating body forming the rotation of the mold assembly is accompanied by CNC control, and may adopt a servo motor for rotational driving, or may be achieved by applying a servo cylinder controlled by servo.

The mold assembly may include a mold assembly having a plurality of molds mounted on the counter blades such that a plurality of molds are mounted on the panel so as to achieve any one of a process selected from shearing, bending, and molding, wherein the mold assembly is a panel to be folded. It includes a shear mold for cutting about, a lower bending mold forming a downward bending, an upper bending mold forming an upward bending, and a round mold for rolling round such as curling.

According to the present invention, it is possible to reduce the economic burden of having a dedicated machine such as a shearing machine, a bending machine, a molding machine and the like as in the prior art, and compared to the case where each of the dedicated units is provided in the facility introduction space of the factory. It is possible to process variously with only the facility, and the space burden is greatly reduced, and it is possible to combine the processing required in a single facility, compared to moving to different dedicated facilities according to different processes such as shearing, bending, and forming between operations. As a result, workability is increased, thereby increasing productivity.

In particular, the present invention is a variety of possible operations, such as V, U, L and channels, curling in the case of bending, and in the case of V bending does not require a separate mold in forming the acute angle or obtuse angle, only by CNC control Since the mold forming the bending is precisely angle controlled, the pressure bending is performed while the mold assembly is moved at the control angle, and thus there is no replacement of the mold, and the bending can be realized at various bending angles.

With reference to Figure 4 looks at the material holder configuration.

The material holder 7 is fixed to the panel 8, which is brought into contact with the counter blade 6 while interposed by the force of the fluid cylinder, and is secured so that the part to be processed such as bending or cutting does not shake or be pushed during processing. It makes up the structure to hold.

The material holder 7 of the present invention mounts the blade 72 which abuts against the surface of the counter blade at the lower end, and mounts the material holder plate 71 and the plate 71 to which the blade is fixed by a plurality of fastening pieces 73. It consists of a fluid cylinder (76) for transmitting a linear kinetic force, on both ends of the plate (71) to form a sliding surface (75) perforated with an oil hole (74), and at the top is spaced apart laterally from the center in the rod bracket ( 77) is made by welding.

The material holder 7 is configured to be coupled to the slope while maintaining the same tip as the tip of the counter blade (6).

Inclined slope formation is adopted to improve workability by widening the rotation angle of the ram as much as possible when the work is achieved, such as when the ram 20 is rotated downwardly or bent while the ram 20 is rotated by the rotor assembly 4.

On the other hand, the present invention may be made of a hydraulic cylinder for servo control by an external drive source.

As described above, the rotor assembly 4 forms a gear disc 42 engaged with the guider 3 to transmit the driving force of the servo motor through the guider 3, and a gear group for transmitting rotational power to the gear disc.

Therefore, when repeating the cutting process to a certain panel size, the panel on the counter blade 6 is press-fixed with the material holder 7 while continuously feeding the panel from one side of the bending device to the other side, and then the bending device is driven to drive the bending machine. The cutting operation can be achieved by driving together.

At this time, the cutting drive of the bending device is prepared at the position where the cutting mold mounted on the ram 20 moves to the upper part of the panel 8, and the cutting is performed when the ram 20 descends by the driving of the fluid cylinder 21. The cutting stroke is completed again as the ram 20 is raised, and then the lowering cutting process is repeatedly performed.

6 (a) summarizes the cutting process and has been described above.

FIG. 6B illustrates a process of pushing upward in the upward direction by using a bending blade of the second mold 23 and bending upward by 90 °.

6C illustrates a process of being pushed downward by 90 ° using the bending blade of the first mold 22.

6 (d), (e) is the angle of rotation of the ram 20 is inclined at an angle of the slope rather than a vertical or horizontal angle can be bent up or down and the bending is at an acute or obtuse angle rather than a right angle It is possible to bend at a desired angle and the control of this angle is by the control of the rotating body assembly 4 which is CNC controlled.

FIG. 6F shows that the bending jig 701 which removes the end blade 72 of the material holder 4 and forms ar for bending in this position is replaced, and the panel 8 material is pressed against the bottom. By rolling to the roll portion of the upper end of the first mold 22 while rotating, the bent panel material matching the jig shape can be obtained.

In this way, the panel 8 cut and cut to a certain size can be used to achieve specific bending or forming in the end or inside the plane.

Moreover, it is also possible to judge that such various types of processing are realized in one installation of the bending device of the present invention, and the types of bending can be any type.

As the bending type of the panel, as shown in FIG. 7, simple bending, folding, hemming, bending, and the like may be continuously processed, and a certain slope may be formed, thereby forming various panels.
