Claims

[Scope of utility model registration request]

A press brake upper die attaching/detaching device that engages the upper die with a mounting portion consisting of a ram or an intermediate plate attached to the ram, and fixes it with one or more tightening members or releases it by loosening it. The mounting portion includes a plurality of main members that can come into contact with the rear surface of the mounting portion and that form a cylinder from the rear of the interior and a space that continues to the cylinder, and a piston that slides within the cylinder. an operating member that penetrates the tightening member and engages with the outer surface of the tightening member; and an operating member that is arranged to penetrate the operating member in the space and constantly applies elasticity to the tightening member via the operating member. A plurality of disc springs are arranged adjacent to each other to fix the upper mold, and pressure oil is supplied to the cylinder of each of the main body members to move the operating member against the elasticity of the disc spring to fix the upper mold. A press brake upper mold attachment/detachment device comprising: a pressure oil supply means for releasing the press brake.
