物と刃物との衝突防止装置。[Claims for Utility Model Registration] (1) A workpiece drive device that supports and rotationally drives a workpiece, a slide unit that is reciprocated in a direction towards and away from the rotationally driven workpiece, and A processing machine that has a blade fixed to a slide unit to cut the workpiece, and moves the slide unit forward in a direction approaching the rotationally driven workpiece to cut the workpiece with the blade. When the slide unit is moved forward to a predetermined position, an air cylinder attached to the slide unit is used to project it in the direction approaching the workpiece, and when the slide unit is further moved forward to a predetermined position, it reaches a position close to the reference plane set in advance on the workpiece. A shear pin whose tip is movable and has a hollow part and a fragile part that breaks and exposes the hollow part when it comes into contact with a workpiece, and a pressure supply device that supplies compressed air into the hollow part formed in the shear pin. 1. A collision prevention device between a workpiece and a cutter in a processing machine, comprising: an alarm device that is activated when air pressure in a hollow portion falls below a predetermined value. (2) The workpiece and cutter in the processing machine according to claim 1, further comprising a control section that stops the operation of the workpiece drive device and moves the slide unit backward when the air pressure in the hollow part formed in the shear pin falls below a predetermined value. Collision prevention device with.
