[0002] Drawing machine is an industrial equipment composed of driving device, lubrication equipment, electrical equipment, hydraulic and pneumatic systems, etc. It is a device for drawing steel. It changes the diameter of steel through drawing to achieve the required diameter. It can draw various rods and pipes of different diameters through various drawing methods such as air drawing and head drawing and changing the mold. Drawing machine is used to draw metal at room temperature. Its capacity is often expressed by the maximum drawing force. Drawing machine can be divided into chain drawing machine, hydraulic drawing machine and drum drawing machine according to different structures.

[0003] When drawing steel pipes, we often use hydraulic drawing machines to draw steel pipes.
