Bolt machining size adjustable cold header
By introducing a bracket, an electric hydraulic lifting rod, a servo motor, and an infrared positioning device into the cold heading machine, the problem that existing cold heading machines can only process a single type of bolt has been solved. This enables rapid adaptation to multiple bolt types and reduces mold change time, thereby improving the processing efficiency of the cold heading machine.

AI Technical Summary
Technical Problem
Existing cold heading machines can only process one type of bolt, and the mold changing process is cumbersome, making it impossible to adapt to the processing of multiple bolt types.
Method used
A cold heading machine with adjustable bolt processing dimensions was designed, comprising a support frame, a cold heading machine body, an electric hydraulic lifting rod, a servo motor, a gear ring, and an infrared positioning device. By rotating the gear ring and using infrared positioning, various bolt models can be adapted, reducing mold change time.
