What if the piston rod breaks during machining

How to deal with the fracture of piston rod during machining?

1. Adjust the moving speed between the product and the induction switch to avoid the occurrence of heat treatment soft belt.

What if there is air leakage when packing the piston rod

With the improvement of automation, people's living standards have been greatly improved. Piston rod is an important piston rod in modern industrial automation production. It is widely used in the field of packaging. It has the characteristics of simple operation, stable characteristics and long service life. Piston rod can realize efficient and orderly automatic operation, and its application value is emphasized more and more. What about air leakage when packing the piston rod? Let's introduce it to you.

Precautions for use of gear reducer

1、 Precautions before reducer assembly

1. The machine should be cleaned before use. Check whether the equipment shaft has bruises and dirt. If so, clean it all.

Gear transmission type and fault response

Gear transmission is a transmission form widely used in mechanical transmission. It has the advantages of accurate transmission, high efficiency, compact structure, reliable operation and long service life.

How to choose the material of quenched and tempered piston rod

In order to increase the service time of the piston rod and reduce the wear of the piston rod, 38crmoalan alloy structural steel is selected as the blank.

What is the processing technology of piston rod?

The piston rod is produced by rolling, because the residual compressive stress in the surface layer is left in the surface layer, which is conducive to the closure of the micro cracks in the surface layer and hinders the development of sedimentation. In order to improve the surface corrosion resistance, the piston rod can slow down the fatigue crack or expansion, so as to improve the fatigue limit of the hydraulic cylinder rod. According to the rolling forming, a layer of cold work hardening layer is produced on the rolling surface layer, which reduces the ductility and plastic deformation of the cutting pair touching the surface layer, thus improving the wear resistance of the surface layer of the hydraulic cylinder rod and preventing the scald caused by cutting. After rolling, the reduction of roughness value can improve the matching characteristics. Together, the friction damage to the seal ring or hydraulic seal is reduced when the rod piston of the hydraulic cylinder moves, and the overall service life of the hydraulic cylinder is improved.
