AI Technical Summary

Technical Problem

The end parts of existing automotive metal exterior trim parts are prone to sagging and deformation during the front punching process, resulting in reduced production efficiency and material utilization.

Method used

Design a trimming die, including a lower die, an upper die, and a cutting blade assembly. The cutting blade punches from the assembly surface of the trim piece to the appearance surface, and the appearance surface is prevented from collapsing and deforming through the cooperation of the guide cavity and guide channel. A return spring and a limit block are used to ensure stable punching.

Benefits of technology

It effectively prevents the appearance from collapsing and deforming, simplifies the repair process, and improves production efficiency and material utilization.

Abstract

The utility model relates to the technical field of automobile ornament processing, in particular to a trimming die which comprises a lower die, an upper die and a cutter assembly. The lower die and the upper die are assembled to form a cavity for accommodating the ornament, and the lower die is provided with a guide cavity communicated with the cavity; the cutter assembly comprises a cutter which reciprocates along the guide cavity, and a blade of the cutter can enter the cavity and is used for cutting off the ornament. According to the utility model, the guide cavity communicated with the cavity is additionally arranged on the lower die, and the cutter is refitted on the lower die from the upper die. In the punching process, the cutter can punch from the assembling face to the appearance face of the ornament through the guide cavity, and therefore the appearance face is prevented from collapsing and deforming.
