装置。 A guide that moves with the upper holder and has a concave or convex portion, and a punch holder that has a convex or concave portion and holds a punch are provided so that the concave and convex portions face each other, and a side surface of the punch holder is provided. By slidably engaging the engaging portion protruding from the upper holder with the zigzag groove circulating along the side surface of the punch holder, the punch holder, which reciprocates in conjunction with the movement of the upper holder, can be moved intermittently. In the punch device, the amount of protrusion of the punch is changed by appropriately engaging each other's concave portions and convex portions. A punch device characterized in that it has a shape that allows it to terminate.
