Abstract

The invention discloses a shock absorber guide and a preparation method thereof, and relates to the technical field of shock absorbers. The key points of the technical solution include the following components by weight: 60-80 parts of 80-mesh iron powder; 15-25 parts of 100-mesh iron powder 6-14 parts of atomized iron powder; 0.8-1.4 parts of copper powder; 0.58-0.78 parts of graphite powder; 0.70-0.84 parts of zinc stearate; 0.08-0.16 parts of sulfur powder. The present invention uses 80-mesh iron powder as the main material, adds 100-mesh iron powder and a small amount of atomized iron powder as auxiliary materials, so that the finer 100-mesh iron powder is filled between the 80-mesh iron powder and then the atomized iron powder is filled in the Between 100-mesh iron powder and 80-mesh iron powder, the structural gap in the guide is further reduced, thereby improving the structural stability and strength of the guide; graphite powder and sulfur powder cooperate with each other to achieve the purpose of strengthening the structural strength of the guide; Zinc fatty acid, as a heat stabilizer and lubricant with good lubricity, will effectively prevent scaling and precipitation inside the guide.

Description

technical field [0001] The present invention relates to a shock absorber, and more particularly to a shock absorber guide and a method for making the same. Background technique [0002] Automobile shock absorber is a kind of damping element, which is a vulnerable part in the process of automobile use. It is one of the important components of automobile suspension system. Sex plays a decisive role. The guide acts as a guide for the movement of the piston rod in the automobile shock absorber, and bears the lateral force generated during the movement of the piston rod. In order to keep the working cylinder and the oil storage cylinder connected, the guide is usually provided with an oil hole. [0003] The Chinese patent with publication number CN107470632A discloses a shock absorber guide, which includes the following components by weight: graphite powder: 1-3 parts, copper powder: 20-40 parts, manganese sulfide Powder: 3-8 parts, nickel powder: 1-5 parts, Bi2(SO4)3 powder: 0...
