Problems solved by technology

[0002] The electric car towing bracket is a left and right part structure with a symmetrical relationship. In the traditional production process, the left and right parts are produced separately, and a cold stamping die for two parts needs to be invested, which takes up more equipment and space, and the material utilization rate is low. The production management is difficult, the operation is cumbersome, the energy consumption is large, the production cycle is long, the investment is large, and the cost is high

Abstract

The invention relates to an electric automobile towing bracket cold stamping production process. The electric automobile towing bracket cold stamping production process is characterized by comprisingthe steps of blanking, falling, performing bending formation, further forming, punching, separating and milling. In the production and processing process, mold and equipment investment is small, the process flow is short, the production period is short, the utilization rate of materials is high, energy consumption is low, production management is facilitated, the labor intensity of workers is low,the production efficiency is high, the cost is low and popularization and application value is achieved.

Description

technical field [0001] The invention relates to a metal part production process, in particular to a cold stamping production process for an electric vehicle towing bracket. Background technique [0002] The electric car towing bracket is a left and right part structure with a symmetrical relationship. In the traditional production process, the left and right parts are produced separately, and a cold stamping die for two parts needs to be invested, which takes up more equipment and space, and the material utilization rate is low. The production management is difficult, the operation is cumbersome, the energy consumption is large, the production cycle is long, the investment is large, and the cost is high. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art, and provide a production process that occupies less equipment and space, has high material utilization rate, less difficulty in product...
