Claims (1)

[Scope of Claim for Utility Model Registration] In a stamping machine for press working by appropriately attaching a local processing tool whose use position, shape, or dimension changes depending on the product type to the upper mold for press working, the above-mentioned The mold incorporates all the local processing tools for each product type that can be moved up and down at the required position, a movable base plate that receives the processing reaction force of each processing tool, and a fluid pressure cylinder that inserts and removes each base plate. , The fluid paths to each of the above fluid pressure cylinders are as follows:
It passes vertically through the flange of the upper mold and the lower part of the ram of the press machine, goes to the perforated fluid path with a seal ring on the mating surface of the two, passes through the electromagnetic directional switching valve attached to the ram, and then the common pressurization is carried out. A sheet metal press stamping device characterized by reaching the fluid source connection end.
