AI Technical Summary

Technical Problem

The feeding mechanism structure of the existing automatic cold heading machine is unreasonable, resulting in a high feeding failure rate, low efficiency and inability to effectively straighten wire raw materials, affecting product quality.

Method used

A feeding mechanism including a base, a fixed wheel, a moving wheel, a sliding seat, a threaded barrel and an elastic central shaft is designed. The alignment of the iron wire is achieved through the cooperation of the sliding seat and the threaded barrel, and the elastic central shaft is used to further ensure the wire alignment. Feed correctly.

Benefits of technology

It greatly reduces the feeding failure rate, improves efficiency, and effectively straightens wire raw materials, improving product quality.
