The high-speed thread rubbing machine is mainly composed of upper body bottom, transmission mechanism, feeding mechanism, thread rubbing mechanism, cooling oil pump, electric box, etc. The bottom of the body is welded by steel plate, the above is the device at the bottom of the body, almost all parts are installed on the body.

When the high-speed thread rubbing machine work, the main motor drives the big pulley, pulley drive spindle eccentric shaft, eccentric shaft through the link, drive the slider reciprocating movement, the spindle, CAM device on the left side of the machine, CAM drive swing rod, after the drive shaft, swing lever drive rocker arm. After adjusting the bolt, the gear rocker arm drives the connecting rod, and the connecting rod drives the screw plate guide rail, so as to drive the screw plate. The feeding tool feeds the blank from the guide groove into the upper space between the two twisting wire plates.

Parallel screw plate has a pair of mold, screw plate through the device on the guide rail to do reciprocating operation, operation to complete a blank rolling, after a small motor to drive the worm gear reducer to complete the blank feeding, small motor also drives the cylinder rotation. The blade device on the cylinder will feed the blank into the guide groove, and then along the guide groove into the twisting wire plate.

What are the five major material selection specifications for the spinning machine? Mainly from the high temperature function, fatigue cracking function, wear resistance, strong tolerance, corrosion resistance, to think.

1, high temperature function

When the working temperature of the rolling machine is higher, the hardness and strength of the material used are reduced, resulting in early wear or plastic deformation of the rolling machine material and failure. Therefore, the rolling wire machine material should have high tempering resistance stability, to ensure that the rolling wire machine material at high temperature, with high hardness and strength.

2, fatigue cracking function

In the process of material operation of thread rolling machine, fatigue and cracking are often caused under the long-term effect of cyclic stress. Its methods include small energy multiple impact fatigue cracking, stretching fatigue cracking, touch fatigue cracking and circuitous fatigue cracking.

3. Wear resistance

When the blank is plastic degeneration in the rolling machine cavity, it moves and slides along the surface of the cavity, so that the surface of the cavity and the blank clash violently, and then causes the data of the rolling machine to fail due to wear. So the wear resistance of the material is one of the fundamental and important functions of the material of the thread rubbing machine. Hardness is the main factor affecting wear resistance. In general, the higher the hardness of the material parts of the thread rubbing machine, the smaller the wear, the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbide.

4, strong patience

Most of the working conditions of the materials of the twisting machine are particularly bad, and some often bear large impact loads, and then cause brittle cracking. In order to avoid the material parts of the twisting machine breaking suddenly during the operation, the material of the twisting machine should have high strength and tolerance.

5, corrosion resistance

Some rubbing machine materials in the operation, due to the presence of chlorine, fluorine and other elements in the plastic suspicion, synthesized after heating out HCI, HF and other corrosive gases, corrosion of the rubbing machine material cavity surface, increase its surface roughness, aggravating wear and failure.
