Abstract

The utility model discloses a stamping die with dislocation detection, which comprises a lower die, a guide sleeve, a guide rod, a template, an upper die, a detection mechanism, and a detection plate. Slide down, when the misaligned part of the thin plate rests on the upper surface of the lower mold, when the press pushes the upper mold fixed to the template to move down, it will simultaneously drive the upper mold and the detection plate fixed to the detection mechanism to move down. The lower surface is lower than the lower surface of the upper mold. Since the thin plate hinders the detection plate from moving down, the pull rod pushes the elastic mechanism to move, the upper push plate remains stationary, and the lower push plate moves to compress the spring, and the pressure sensor can detect the pressure value. When the thin plate is dislocated, it occurs in a certain direction of the lower mold. Therefore, the data detected by the four pressure sensors must be quite different, and it can be judged that the dislocation has occurred. The device is simple and can automatically detect sheet misalignment, effectively reducing the risk of mold damage.
