The moving components of this equipment are driven by servo motor and ball screw during shrinking operation. The motor rapid movement and shrinking length can be set directly on the human-machine interface during shrinking operation, which is easy to operate and can reach a shrinking degree of 50mm. The equipment storage hopper adopts the middle discharging method to avoid discharging two materials at a time and only ejecting one side of the copper tube. The material transfer method uses a cylinder plus a slide rail method, which makes the material transfer more stable. The shrinking high-speed motor has a maximum speed of 24,000 rpm and adopts front cooling. During the shrinking operation, the PLC controls the air blowing.
