Abstract

The invention relates to a secondary punching wheel cover forming punching mold in the field of stamping molds. The upper portion of a lower mold base is connected with a lower mold core, and the lower portion of an upper mold base is connected with an upper mold core. Four corners of the lower mold base are symmetrically provided with guide column seats and guide columns and matched with self-lubricating sliding guide seats of the upper mold base. Upper and lower mold hard limiting and secondary limiting blocks are arranged beside the guide column seats and the self-lubricating sliding guide seats, the lower mold base is provided with at least one rotating press plate, the rotating press plate is connected with a sliding block, and the sliding block is connected with a sliding block limiting rod and a limiting ring. The upper mold base and the lower mold base are provided with guide rod air cylinders, two sides of the lower mold core are provided with air cylinders, piston rods of the air cylinders are connected with the sliding block, one side of the sliding block is provided with the sliding block limiting rod and the limiting ring, and sliding block press plates arranged symmetrically are arranged at two ends. The secondary punching wheel cover forming punching mold has the advantages of being high in product punching accuracy, free of splitting and shrinkage and the like.

Description

technical field [0001] The present invention relates to a stamping die, more particularly, the present invention relates to a [0002] It is a secondary punching wheel cover forming punching die that produces layer shrinkage when the product is punched. Background technique [0003] The deficiency of the prior art is that the processing method of punching the wheel cover is to use one-time punching and forming. The original limit can directly achieve the state of punching in place, that is, when the mold is in place, the mold is also punched while forming. . The advantage of this one-time molding method is that the structure of the abrasive tool is simple, and the processing cost seems to be slightly reduced. However, the stamped product has defects, which are prone to layer shrinkage, which affects the processing accuracy of the product. Contents of the invention [0004] The purpose of the invention of the present invention is to overcome the deficiencies in the pr...
