記載のパンチ自動交換装置。[Claims for Utility Model Registration] (1) A folding process in which a plate-shaped workpiece 7 is bent between a punch 4 attached to the lower part of a vertically movable ram 3 and a die 6 fixed to a fixed frame 1a. In a bending machine, the ram 3 is moved up and down by a vertical drive cylinder 20, and a front and rear drive cylinder 1
7, an exchange punch 27 is attached to the adapter 21, the adapter 21 is lowered from the standby position by the vertical drive cylinder 20, and is attached to the ram 3 by the longitudinal drive cylinder 17. standard punch 4
After moving it downward, it is raised by the vertical drive cylinder 20, and the tip of the standard punch 4 fits into the V groove 21d provided in the adapter 21, so that the standard punch 4 and the exchange punch 27 are exchanged. Automatic punch exchange device for bending machines. (2) When the adapter 21 with the replacement punch attached is raised and the V groove 21d is fitted to the tip of the reference punch 4, the upper surface of the adapter 21 and the reference punch 4
Claim 1: A minute gap 32 is formed between the punch holder 5 fixed to the ram 3, or between the V groove 21d and the tip of the reference punch 4.
Automatic punch changing device described.
