Abstract

The invention relates to the technical field of valve rocker arm shafts, in particular to a machining process of a high-strength wear-resisting valve rocker arm shaft. A valve rocker arm shaft blank comprises, by weight, 80-150 parts of iron, 0.3-0.8 part of chromium, 0.6-0.9 part of high-wear-resistant carbon black, 1-3 parts of titanium, 0.8-1.7 parts of silicon, 0.2-0.5 part of boron, 1.2-1.8 parts of manganese, 0.2-0.5 part of copper, 0.1-0.8 part of lithium, 0.4-0.9 part of zinc, 0.2-0.7 part of cobalt, 0.02-0.06 part of vanadium and 0.13-0.48 part of nickel. According to the machining process, the chromium, the high-wear-resistant carbon black and the titanium are added to an alloy material and used for improving the wear resistance of the valve rocker arm shaft, so that the servicelife of the valve rocker arm shaft is prolonged, and the oxidation resistance of the surface of the valve rocker arm shaft is improved through blackening treatment on the valve rocker arm shaft.

Description

technical field [0001] The invention relates to the technical field of valve rocker shafts, in particular to a processing technology for high-strength wear-resistant valve rocker shafts. Background technique [0002] The valve rocker shaft is used in the engine of the car. The surface wear resistance of the existing valve rocker shaft is low. After a long time of work, the surface of the valve rocker shaft will cause more wear, thereby reducing the Shaft service life. Contents of the invention [0003] The object of the present invention is to solve the disadvantage of low surface wear resistance of the door rocker shaft in the prior art, and propose a high-strength wear-resistant valve rocker shaft processing technology. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] Design a high-strength wear-resistant valve rocker shaft processing technology, including the following steps: [0006] S1, select t...
