Abstract

The invention discloses a processing technology for precision seamless steel pipes for gas springs. The seamless steel pipes include a pipe body, a functional layer and a coating, the inner side wall of the pipe body is provided with a first coating, and the pipe body The outer wall of the body is provided with a second coating, and a functional layer is provided between the first coating and the inner surface of the tube, and between the second coating and the outer surface of the tube. The present invention realizes the improvement of the function of the seamless steel pipe produced through the structural setting, components and preparation process. The functional layer improves the surface hardness and friction resistance of the steel pipe, maintains the plastic toughness of the center, isolates the steel pipe from the coating, and facilitates the first coating. The layer and the second coating play their due role and improve the performance of the seamless steel pipe. The first coating improves the sealing performance, lubricity and friction resistance of the seamless steel pipe, and reduces the quality of the piston and pressure of the gas spring produced. The friction between the cylinders, the second coating improves the anti-corrosion ability, thermal conductivity and impact resistance of the seamless steel pipe, prolonging its service life.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a processing technology of precision seamless steel pipes for gas springs. Background technique [0002] In the fields of automobiles, aviation, medical equipment, furniture, machinery manufacturing, etc., an industrial accessory - gas spring is often used. The main functions are support, buffering, braking, height adjustment and angle adjustment. It consists of piston rod, piston, It is composed of sealing guide sleeve, filler, pressure cylinder and joints. The pressure cylinder is filled with inert gas or oil-gas mixture, which can increase the pressure of the closed pressure cylinder. The piston rod is located in the pressure cylinder, and the pressure difference formed between the inside and outside of the piston To realize the movement of the piston rod, the speed is relatively slow and easy to control. Among them, the pressure cylinder in the gas spring is seamless steel pipe, whi...
