Abstract

This utility model relates to the field of punch drive structure technology, and discloses a punch drive structure for stamping molds of mechanical devices. It includes a mounting base, a connecting member fixed to the side wall of the mounting base, and a telescopic cylinder passing through the top of the connecting member. A punch seat is provided at the power output end of the telescopic cylinder. This utility model provides a fixing seat inside the punch seat for fixing the punch rod. When the adjusting screw rotates, the displacement plate slides downward in conjunction with the sliding port, causing the fixing seat to move downward inside the punch seat. This causes the punch rod to move downward inside the punch seat, thereby changing the extension length of the punch rod at the bottom of the punch seat. This allows for adjustment of the punching depth of the punch rod, extending the stamping depth of mechanical devices and improving the applicability of the punch drive structure.
