Abstract

The invention relates to a die, in particular to a positioning stamping die. The positioning stamping die comprises an upper die, wherein a stamping head is connected under the upper die, and a lowerdie is arranged below the stamping head; a plurality of first fixing plates are arranged on the lower die, and a plurality of first fixing teeth are arranged on the upper surface of each first fixingplate; a plurality of first clamping rods are movably arranged on the outer side of the lower die, a plurality of first pawls which can be matched with the first fixing teeth are arranged at the bottoms of the first clamping rods, and the side walls of the ends, close to the first fixing plates, of the first clamping rods are hinged to baffles; a plurality of third fixing teeth are arranged on theinner walls of the first clamping rods, and second clamping rods are arranged in the first clamping rods in a sliding mode; and second pawls capable of being matched with the third fixing teeth are arranged on the two sides of the second clamping rods, and a plurality of third pawls which can be matched with the second fixing teeth are arranged at the bottoms of the second clamping rods. According to the positioning stamping die, the problem that a workpiece can move in the stamping process is solved.

Description

technical field [0001] The invention relates to a mold, in particular to a positioning stamping mold. Background technique [0002] Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] During the stamping process, the workpiece will be moved by the impact force of the stamping head, causing the stamped shape of the workpiece to deviate from the expected shape. At the same time, the workpiece is also prone to warping, which requires secondary processing of the workpiece, which increases the processing cost and reduces the processing cost. efficiency. In addition, most of the existing stamping dies can only stamp one type of workpiece, and the utilization rate of the stamping die is low. When different workpieces need to be stamped, different stamping dies need to be switched, and the cost is high. Contents of the ...
