AI Technical Summary

Technical Problem

In existing technologies, the sheared surfaces of product objects suffer from tearing, which prevents the sheared surfaces from achieving a glossy finish, and the mold design increases manufacturing costs.

Method used

A multi-segment chamfering tool with a bright shearing surface is used. By changing the cutting edge of the mold part from a single segment to a multi-segment chamfer, and adding R0.5 at the top, combined with CNC polishing technology, the chamfering structure is optimized to improve the quality of the shearing surface.

Benefits of technology

This achieves a glossy finish on the sheared surface, reduces manufacturing costs, and improves the overall appearance quality of the product.

Abstract

本实用新型涉及倒角工具技术领域，公开了剪切面光亮多段式倒角工具，包括产品物件，所述产品物件的顶部设置有第二层深度，所述第二层深度的顶部设置有第一层深度，所述第一层深度和产品物件的相邻之间设置有第一层倒角，所述第一层倒角的内侧设置有第二层倒角，所述第一层深度的底部左侧设置有V形压料环，所述V形压料环的底部右侧设置有顶端R0.5。本实用新型中，通过将模具备品零件刃口的倒角由原来的一段式更改为多段式倒角，目的是材料在夹持剪切时顶端R0.5方便材料剪切的流动，而第二层倒角作用是过渡引导材料挤压，将刃口的抛光工艺做到极致，这样冲出来的剪切面就达到光亮的效果即可，从而满足操作人员的日常使用需求。
