The wire drawing machine is one of the main equipment of the metal wire processing as well as the cable and wire industry. Wire drawing is a metalworking process that can reduce the cross-section of a wire by pulling the wire through a single, or series of, drawing dyes. Wire drawing is used in a wide range of applications like electrical wiring, cables, tension-loaded structural components, springs, paper clips, spokes for wheels, and stringed musical instruments.  It usually constitutes the paying off, water cooling, winding up, winding displacement and other components. Its electric drive part is mainly realized by paying-off motor, winding-up motor and winding displacement motor. The wire drawing machine belongs to the constant-torque load.

Processes of the wire drawing machine:

Wire sending: As to the sending of the metal wire, its control doesn't have too high precision requirement to the whole wire drawing machine link. For the most wire drawing machine, the operation of wire sending is realized through VFD driving the wire sending rack. However, there are also some wire drawing machines controlled by double VFDs. Even some are delivered into the wire drawing machine through the drawing of the thread tension in the wire drawing process, thus realize free wire sending.
Wire drawing: The wire drawing process is the most important working step of the wire drawing machine. The wire drawing diversifies greatly as to different metal products, different wire variety and requirement.
Rewinding: The working speed of the rewinding link decides the manufacturing efficiency of the entire wire drawing machine. It is also the part which is the most difficult to control in the system. In the rewinding process, the normal control technology is to realize the winding of the metal products through synchronous control and tension control.
