AI Technical Summary
Existing cold heading machines are prone to problems such as workpiece sticking during unloading, mold temperature changes affecting unloading effect, and wear of unloading parts, resulting in low production efficiency and high equipment maintenance costs.
The design incorporates an ejector cylinder to drive the ejector block, clean high-pressure airflow to disperse the workpiece, a spiral guide cavity cooling system, and a removable wear-resistant protective liner. Combined with a vibration motor and coolant circulation system, it enables rapid demolding of the workpiece, mold temperature control, and protection of the blanking plate.
It improves unloading efficiency, avoids workpiece jamming and mold thermal deformation, extends equipment lifespan, and reduces maintenance costs.
