Description

technical field [0001] The invention relates to a manufacturing method of a wear-resistant transmission connecting rod assembly, in particular to a manufacturing method of an automobile turbocharged wear-resistant transmission connecting rod assembly. Background technique [0002] With the improvement of social living standards, small passenger cars have become a necessary means of transportation for social families. Based on the impact on the social environment, major automakers vigorously promote energy conservation and emission reduction for their own brand models. Low fuel consumption and low emissions have become the mainstream of public knowledge, and they have made due responsibilities for the social environment. For this reason, major automobile manufacturers have promoted low-fuel-consumption turbocharged small-displacement vehicles, using turbocharging technology to convert the exhaust gas into power again to achieve the effect of energy saving and emission reducti...

Problems solved by technology

[0003] In the design of the product, due to the special characteristics of high wear resistance and high working temperature of this component in the turbocharger, it is required to select materials such as heat resistance and certain anti-corrosion properties, such as: 1.4571 is SUS316Ti Material, the minimum thickness of the connecting rod is 6mm, with the characteristics of high precision requirements such as the size of the installation work surface, shape and position tolerance, and position tolerance, it is impossible to use a reasonable method to complete the production; while foreign countries use 6mm thick plate materials for stamping and forming , the mold life is low, expensive, material utilization and production efficiency are low, quality is unstable, and it is not suitable for the needs of the existing domestic and foreign markets
