Copper wire wire-drawing machine takes advantage of copper’s extensibility, uses power to wind and pull the cooper wire, so that the copper wire deforms because of producing pultrusion plasticity forwardly by wire-drawing die, which makes the diameter smaller, achieving the diameter size that we need. Wire-drawing machine consists of two parts: extending wire and rewinding the wire, adjust the stretching and winding up wire speed by the AC motor drive, so as to match both.
Wire-drawing machine is divided into three parts: winding, extending (drawing wire) and rewinding:
According to the process flow of pulling and drawing, the following equipment need to be used when copper bar is stretched to copper wire.
Control principles of the above-mentioned four pieces of equipment are of the same. Two AC Motor Drives are used to control, so double variable frequency wire-drawing machine, currently, multiple drives can also be used to wind up.
Rewinder: the rewinding is passive, due to the small power rating in winding and rewinding, torque motor is used to wind wire considering the cost.

A coiling block to wind, same as general drive
Two coiling block to wind at the same time, a host drives two motors to wind up, with a slight difference from traditional machine in machinery, the host cone pulley is two sets of mold design.
Advantages of double winding are: in the premise of same investment, it substantially improves production efficiency and greatly reduce the floor space of same two machines, two wire-rewinding machines are independent of each other. When one doesn’t work or in other circumstances, It does not affect the normal operation of the other machine.
GK620 is a general-purpose AC drive with V/Hz and sensor-less vector control. It’s powerful in performance, reliable in quality and optimized in structure. GK620 is widely used in various applications including air compressor, crane & lift, metal processing, mining, mills, food and beverage processing, packaging, conveyor, textile, plastics, fan & pump, etc.
GK820 is the high-performance series which covers an entire range of applications, particularly for demanding ones that require precise speed control, torque control and fast response, etc.
