Description

Technical Field

[0001] The present invention relates to the technical field of steel processing, and in particular to an automatic steel drawing machine and a working method. Background Art

[0002] A drawing machine is a device used to draw metal at room temperature. Its capacity is often expressed in terms of maximum drawing force. Drawing machines can be divided into chain drawing machines, hydraulic drawing machines, drum drawing machines, etc. according to their different structures. Drawing is a plastic processing method in which a metal blank is deformed by passing it through the die hole of a drawing die. During the drawing process, the blank undergoes plastic deformation in the drawing die. After passing through the drawing die, the cross-sectional shape and size of the blank are the same as those of the die hole outlet of the drawing die. Therefore, by changing the shape and size of the die hole of the drawing die, the corresponding drawn product can be obtained.

[0003] Taking the chain drawing machine as an example, the chain drawing machine uses a chain to drive a mobile trolley to move on the track. The trolley pulls one end of the steel to move on the track. The steel is shaped after passing through the drawing die. However, due to the forced friction and extrusion between the steel and the inner wall of the drawing die, the steel is formed. In this process, the friction between the inner wall of the drawing die and the surface of the steel may produce spots, scratches or rust. This type of steel needs to be polished in the next step, but because the steel is drawn into a specific shape, it will consume a lot of time during polishing, which reduces the efficiency of the steel drawing process.
