Abstract

PURPOSE:To prevent seizure, galling, wrinkle, etc. and to improve yield by pressing a belt material from the transverse direction thereof while holding both sides thereby performing edge bending. CONSTITUTION:Belt-like work W is inserted into a charging groove 13 from one side thereof, then a sliding part 19 is lowered by a ram P against the repulsive force of a cushion pin 22. The part of the work W in the inserted part 19b transfers into a working groove 19a, and a bending punch 20 contacts with the work W. The work W supported at both ends on the bases of the charging grooves 13, 13 for the material is bent from the central part and is deformed to a prescribed shape in conformity with the shape on the bottom surface of the punch 20. The ram P is moved upward where the deformation is completed at the assigned bottom dead point and after insert blocks 14, 14 are removed, the sliding part 19 is moved upward to the initial position by a cushion pin 22 thereby removing the work W.

Conventionally, in order to create bent frames for automobile bodies, etc., a large trim die was used as shown in Figure 1.
After trimming a processed product K into a bent predetermined shape from a wide flat sheet metal material A, a form die was used to form the product F. Since the parts were wasted as scraps S, an edge bending type as shown in Fig. 2 was devised.

However, in such conventional edge bending type,
Since the mold structure was such that the workpiece was pushed in from the top, there was a strong tendency for wrinkles to form at the beginning of the bending process, and the workpiece was firmly against the inner surface of the longitudinal groove of the holder in places, so the bending punch was not fully inserted. Not only does it not work, but also drawing scratches occur on the workpiece, and due to the increase in plate thickness, the side surface of the workpiece is damaged.
