０の送りが案内されるのである。As described in Japanese Patent Application No. 58-29598, a conventional press processing apparatus sequentially performs a plurality of press processes while a strip-shaped material is fed in its longitudinal direction, forming a desired shape. There is a progressive type that molds products. In this type of press processing equipment, multiple press processing machines are
The materials are arranged at regular intervals, and the materials must be accurately guided and fed in the direction of the arrangement. However, since it is not possible to guide the part to be processed by the press machine, the both sides of the material 100 in the width direction are guided as shown in FIG. This material 10
0 is processed symmetrically with respect to a center line extending in the longitudinal direction while being fed in the direction indicated by the arrow in the figure, so that two products are molded at a time. Each semi-molded product 102 in the middle of molding is converted into a material 100 in the final process.
The materials 100 are connected at the center in the width direction until they are separated and made into a product, and the materials 100 extend laterally in opposite directions from the joints connecting adjacent semi-molded products 102. Formed transverse bone 104
and a pair of vertical ribs lσ6 extending in the longitudinal direction of the material 100 and connecting the protruding ends of the horizontal ribs 104, respectively.
07. This crosspiece 10
7 is formed in the initial step of a series of press working, and each vertical rib 106 is guided in movement by the side walls of guide members 108 disposed along the longitudinal direction on both sides of the material 100. Material 1 from member 108
The material 10 is prevented from rising upward by the bottom portion 110 extending toward the 00 side.
The feed of 0 is guided.
発明が解決しようとする問題点
しかし、上記のようにして素材１００を案内する場合、

内部材１０８が設けられるため、プレス加工装置が大形
となる問題もあった。Problems to be Solved by the Invention However, when guiding the material 100 as described above,
Providing the horizontal ribs 104 and the vertical ribs 106 causes a problem in that the yield of material decreases significantly and the cost of the product increases. Moreover, since the width of the material 100 becomes large and the guide member 108 is provided on the side thereof, there is also a problem that the press processing apparatus becomes large in size.
この問題は、製品が２個ずつ成形される素材がその側方
において送りを案内される場合に限らず、製品が１個ず
つ成形される場合等においても素材がその側方において
案内される場合に同様に生ずる問題である。This problem occurs not only when the feed is guided on the side of the material that is molded into two products at a time, but also when the material is guided on the side when the product is molded one by one. This is a similar problem.

る。This material 10 is in the form of a thin strip, and while being fed in the direction indicated by the arrow in the figure, it is sequentially subjected to a plurality of press operations to form a product in a predetermined shape. The material 10 is previously wound into a roll, and is supplied to a press processing device by a supply device (not shown). In the press processing apparatus of this embodiment, punching is performed in the first step, and the semi-formed product 12 has a shape that approximately corresponds to the expanded shape of the product obtained by this press processing apparatus.
is formed. Next, as the material 10 is fed intermittently, the semi-molded product 12 is sequentially subjected to six press processes A to F (with an idle process in between, as the case may be). During this series of press working, each semi-molded product 12 is connected at the center in the width direction of the material 10, and is separated from the material 10 at the final stage to obtain a product 14. . Note that this material 10 is processed symmetrically with respect to a center line extending in the longitudinal direction, so that two products 14 can be obtained each.

のいずれからも切り離される。In the center of the material 10 in the width direction, cut pieces 20 serving as engagement portions are formed in dots at appropriate intervals along a straight line extending in the feeding direction of the material 10. 20 pieces each
is formed at the same time as the pilot pin hole 22 into which the pilot pin for positioning the semi-molded product 12 is inserted in the initial process when the semi-molded product 12 is formed by punching. As shown in FIGS. 3 and 4, this cut piece 20 is formed by cutting and bending a part of the material 10 so that it extends downward from the material 10, leaving one side extending in the width direction. In the final stage, the product 1
4 is separated from the material 10, the material 10. Product 14

０を送り位置に戻すのである。The lifter 26 has a longitudinal shape as shown in FIG. 2, and is fitted into a groove 30 of a lower mold 28 disposed below the material 10 so as to be movable up and down in an attitude extending in the feeding direction. ,
A plurality of rods 32 are fixed to the lower surface thereof with bolts 34 at appropriate intervals in the longitudinal direction. These rods 32 are fitted into stepped holes 36 formed in the lower die 28 so as to open into the grooves 30, and are movable up and down.
is biased in a direction that causes it to rise. The lifter 26 has its upper part protruding from the upper surface of the lower mold 28 when not being processed, and maintains the material 10 at a feeding position where it is raised a short distance from the upper surface of the lower mold 28, while during processing, it is moved by lowering of the upper mold (not shown). As the material IO is lowered, it is lowered against the biasing force of the spring 38, and when the upper die is raised, it is raised by the biasing force of the spring 38, and the material 1
0 is returned to the feed position.

の歩留りを向上させ得る効果が得られる。As shown in FIGS. 2 and 3, a groove 40 is formed in the upper surface of the lifter 26 and extends in the longitudinal direction thereof. The width of this groove 40 is formed to a size that allows the cut piece 20 to engage the side surfaces of 'a40 on a pair of side surfaces parallel to the feeding direction and to move within the groove 40,
After the cut pieces 20 are formed in the initial step, they are fitted into the grooves 40, and the movement of the material 10 is guided by the engagement between the cut pieces 20 and the grooves 40. In this embodiment, the beam lid 26 functions as a guide member, and in this way, the material 10 is provided below and the lid 26
By being guided by 6, there is no need to provide a crosspiece as in the case where the material is guided on the side thereof, and the yield of the material can be improved.
また、リフタ２６が案内部材を兼ねることにより、部品
点数が少なくて済み、プレス加工装置を安価に製造する
ことができる。Moreover, since the lifter 26 also serves as a guide member, the number of parts can be reduced, and the press working apparatus can be manufactured at low cost.
