The invention relates to the technical field of
stamping processing equipment, and discloses an automatic trimming method for a
stamping die, which comprises a supporting box body, the inner side of the middle part of the supporting box body is fixedly sleeved with a rotary positioning mechanism, the top surface of the rotary positioning mechanism is fixedly provided with a lower
stamping die, and the lower stamping die is internally and movably sleeved with a workpiece; the two sides of the top face of the workpiece are movably connected with
constant pressure mechanisms, the bottom faces of the
constant pressure mechanisms are fixedly connected to the top face of the middle of the supporting box body, a lower pressing sleeve is arranged at the top of the workpiece, and the inner side of the top of the lower pressing sleeve is fixedly connected with an upper stamping die in a sleeved mode. According to the automatic edge
cutting device for the stamping die and the edge
cutting method of the automatic edge
cutting device, through mutual cooperation of the
constant pressure mechanism, the adjusting composite box body, the edge cutting mechanism and the advancing mechanism, redundant materials of a workpiece are subjected to automatic edge cutting operation after the workpiece is stamped, the integrated stamping and edge cutting
machining technology is achieved, the
production cycle of the workpiece is shortened, and the production efficiency is improved.
