AI Technical Summary
The small linkage clearance in the back passage mechanism of the existing cold heading machine makes maintenance inconvenient and cannot be flexibly adjusted according to different mold hole positions, resulting in overlapping motion trajectories and part collisions.
A motor-driven turntable drives the connecting rod and traction rod to reciprocate. The synchronous movement of the slide rod is achieved through a combination of connectors and screw nuts. The position of the mold hole can be flexibly adjusted through detachable and threaded connections.
It simplifies the equipment maintenance and repair process, provides flexible mold hole position adjustment, and avoids overlapping linkage movement trajectories and part collisions.
