AI Technical Summary

Technical Problem

During the production process of cold heading machines, the product falls during the transmission process, resulting in empty punching, resulting in the size not meeting the drawings, and the existing technology has not effectively solved it.

Method used

Design a cold heading machine mold structure to prevent air-brushing, including a die assembly and identification mechanism, use sensors and transmission rods to detect the existence of workpieces, judge the air-brushing phenomenon through high and low level signals, and stop the machine in time with the alarm to avoid abnormal products being mixed into qualified products.

Benefits of technology

It realizes the timely detection of air-firing phenomena, avoids losses and abnormal products infusion, simplifies the air-firing identification work, and improves the level of production automation.

Abstract

The cold header die structure comprises a female die assembly, a male die and an identification mechanism, the female die assembly comprises a first female die, a second female die and a third female die, the second female die is arranged in an inner cavity of the first female die in a sliding mode, the third female die is fixedly arranged in the inner cavity of the first female die, and a spring is arranged between the second female die and the third female die; the two ends of the spring abut against the second female die and the third female die respectively. The recognition mechanism comprises a sensor and a transmission rod, the sensor is arranged in the containing cavity, and the transmission rod is slidably arranged in the guide hole. The device has the technical effects that the empty punching phenomenon can be found in time in the machining process, field personnel can be reminded in time in cooperation with the alarm, abnormal products can be taken out conveniently, and the abnormal products subjected to empty punching are prevented from being mixed into qualified products; the production process can be automatically monitored, loss caused by idle beating of the cold header is avoided, abnormal products are prevented from being mixed into qualified products, and the effect is good after practical application.
