Spring for vertical damping assembly and production process of spring

Abstract

The invention relates to the field of springs, and particularly discloses a spring for a vertical damping assembly and a production process of the spring. The spring for the vertical damping assembly comprises a spring body, the spring body is coated with a corrosion-resistant layer, and slurry of the corrosion-resistant layer is prepared by mixing the following raw materials in parts by weight: 20-50 parts of graphene, 1-10 parts of polycarbonate, 10-25 parts of propylene carbonate, 15-30 parts of organic silicon and 3-10 parts of a diluent; and the production process comprises the following steps: S1, performing a spring coiling procedure: putting a spring steel wire made of 60Si2MnA into a spring machine for spring coiling to obtain a spring semi-finished product; and S2, preparing a spring finished product through heat treatment, tempering, shot blasting, phosphating cleaning and spraying of a corrosion-resistant layer 60Si2MnA. The process has the effect of improving the corrosion resistance and wear resistance of the spring.

Description

technical field [0001] The present application relates to the field of springs, more specifically, it relates to a spring for a vertical damping assembly and a production process thereof. Background technique [0002] At present, in various industries such as vehicles, ships, aviation, electromechanical, and industrial equipment, it is inevitable to use vertical shock absorbing components for shock absorption. Springs are usually used in shock absorbing components. The main function of the spring is to control the movement of the mechanism or the position of the parts, and to cushion the shock. The quality of the spring's comprehensive performance is determined by its internal and external factors. The material of the spring determines its internal factors, and the load and dimensional accuracy determine its external factors. [0003] Since the spring realizes shock absorption through its own reciprocating motion, the spring itself bears a large impact during the reciprocat...

AI Technical Summary

Problems solved by technology

[0003] Since the spring achieves shock absorption through its own reciprocating motion, the spring itself bears a large impact during the reciprocating motion of the spring, and the spring body is prone to collisions, which often cause wear of the spring

And because the springs used in the vertical shock absorbing components are mainly used for outdoor equipment, they are often eroded by rainwater. The rainwater forms water films or drops on the surface of the springs, which easily corrodes the springs and seriously reduces the service life of the springs.
