AI Technical Summary

Technical Problem

The existing multi-station cold heading machine has a complex die-gutter mechanism, and the transmission mechanism and clamping action have a synchronization deviation, which leads to unstable workpiece transmission and high maintenance costs.

Method used

A front stop mechanism for ejecting the die of a nut ejector is designed. The stop plate is driven by the reciprocating motion of the stop seat, the clamp push rod, and the cutter seat push rod, ensuring stable coordination between the stop action and the workpiece conveying action. A parallelogram linkage mechanism and a return spring are used to achieve stable oscillation. The structure is simple and easy to maintain.

Benefits of technology

This achieves stable coordination between the die-stopping action and the workpiece conveying action, reducing maintenance costs and improving the operational stability of the nut machine.
