AI Technical Summary

Technical Problem

In the existing technology, when DR molding and FO molding are combined, the upper mold is prone to damaging the molded workpiece when the upper and lower molds are separated, which leads to processing difficulties.

Method used

Design a stamping die, including an upper die plate, a lower die plate, and a blocking component. The blocking component moves to the bottom of the upper die plate when it separates, preventing the upper die plate from contacting the formed workpiece. The upper and lower die plates are elastically connected to clamp the sheet metal, and the upper and lower pressure rings clamp the edges of the sheet metal.

Benefits of technology

It effectively prevents deformation of the formed workpiece, ensures workpiece quality, and avoids damage to the workpiece when separating from the upper template.

Abstract

This application discloses a stamping die, which includes an upper die, a lower die, and a blocking assembly. The die includes an upper base and an upper pressure assembly, the upper pressure assembly being elastically connected to the upper base. It also includes a lower base and a lower pressure assembly, the lower pressure assembly being fixedly connected to the lower base. The upper and lower pressure assemblies are used to clamp and form a sheet metal. When the upper pressure assembly moves away from the lower pressure assembly, the blocking assembly moves to the bottom of the upper pressure assembly. When the upper and lower die are separated, the sheet metal is placed on the lower die. As the upper die gradually approaches the lower die, the upper and lower pressure assemblies gradually clamp the sheet metal, thereby forming it. After the sheet metal is formed, the upper pressure assembly gradually moves away from the lower pressure assembly, while the blocking assembly reaches the bottom of the upper pressure assembly, limiting the limit position of the elastic movement of the upper pressure assembly and preventing the upper pressure assembly from contacting the formed workpiece through elastic movement, thus preventing deformation of the formed workpiece.
