Abstract

This utility model provides a punching die, relating to the technical field of metal parts manufacturing. The punching die includes a base plate, on the upper surface of which a rotatable circular turntable is slidably connected. Two hollow molds are fixedly connected to the upper surface of the turntable, with the centers of the two molds aligned in a straight line. A punching mechanism for punching holes in sheet metal is provided on one side of each mold. The punching die moves a mold containing sheet metal to the punching mechanism via the turntable, punching holes in the sheet metal inside the mold. Workers on the other side, away from the punching mechanism, replace the sheet metal in another mold, repeating the process. This ensures that the location for replacing the sheet metal is not in the same place as the punching location, reducing the risk of injury. This solves the problem of existing methods that require placing hands between the upper punch and lower die to adjust the position of the sheet metal, which is highly dangerous.
