Cold heading manufacturing process of copper ring for automobile generator

Abstract

The invention provides a cold heading manufacturing process of a copper ring for an automobile generator. The process is characterized in that a conveyer belt is adopted and is provided with first, second and third stamping positions; the conveyer belt is connected with a step drive mechanism; a pre-punch is arranged above the first stamping position; a second punch is arranged above the second stamping position; a third punch is arranged above the third stamping position; a cold heading die is arranged on the conveyer belt and is provided with a circular cavity; the step drive mechanism can drive the cold heading die to be below the first punch, second punch or third punch; when carrying out cold heading and stamping, copper bars are selected as the raw materials and are cut into copper sheets, the copper sheets are put in the cavity of the cold heading die and cold heading and stamping are carried out in the first, second and third stamping positions in sequence, thus obtaining the finished product. The process has the following beneficial effects that: the conveyer belt is adopted for conveying, the punches are adopted for cold heading and punching, the process is easy and convenient to operate, a few workers are needed, the labor cost is greatly lowered and the production efficiency is improved; and the cold heading and punching modes are adopted, thus avoiding material waste.

Description

technical field [0001] The invention relates to a cold heading manufacturing process of copper rings for automobile generators. Background technique [0002] The copper ring is an important part in the automobile generator. In the prior art, the turning process is adopted, and there are the following defects: 1.
