The drawing unit is composed of mechanical equipment, lubrication equipment, electrical equipment, hydraulic and pneumatic systems, etc.
The mechanical part is composed of a unwinding machine, a pre straightening machine, a combined pulling machine, a horizontal straightening machine, a vertical straightening machine, a hydraulic shear, a conveyor, a shaped cutting table, a polishing straightening machine, a turning device, an automatic chamfering machine, etc.
A drawing machine is a device for drawing metal materials. By drawing, the diameter of the metal material is changed to meet the required diameter requirements. Various specifications and diameters of bars and pipes can be drawn through various drawing methods such as air drawing, swashhead drawing, and changing the mold. At present, the most advanced drawing machines are various models such as 5t-1000t produced by Zhejiang Yiforging Company.
