Rear steering engine lining machining technology

Abstract

The invention relates to a rear steering engine lining machining technology, and belongs to the field of automobile accessory producing and manufacturing. Discharging, reshaping, hole stretching, flatupsetting, turning, punching and turning are sequentially adopted in the rear steering engine lining machining technology. Cold extrusion and machining are combined, the technology is reasonable andmature, the product size is stable, economic benefits are high, the product size requirement and the product dimensional tolerance can be achieved, and universality is achieved; and through die and program adjustment, a series of linings different in specification can be machined.

Description

technical field [0001] The invention relates to a technology, in particular to a rear steering bushing processing technology, which belongs to the welding parts of the steering mechanism of the automobile chassis, is suitable for mass production, and belongs to the field of auto parts manufacturing. Background technique [0002] At present, the welding connection bushing of the automobile chassis is a kind of multi-directional force, which requires high mechanical properties of the product; the existing processing technology is relatively complicated, and the mechanical properties of the obtained product materials are not high, and the assembly dimensional accuracy is low. The required precision requirements cannot be met, the production efficiency is low, the labor cost is high, and it is not suitable for mass production. [0003] The publication date is July 10, 2013, and the Chinese patent with the publication number 101979889B discloses a utility model patent named "a pr...

Problems solved by technology

The processing method of the bushing in this patent is to implement the following steps on the copper-based bimetallic steel strip: 1) blanking; 2) punching the buckle; 3) punching U-shaped; 4) full circle; 5) finishing circle; 6 ) Grinding the outer circle; 7) Boring the inner circle, which is characterized in that: the step 5) finishing the circle, step 6) grinding the outer circle, and step 7) boring the inner circle through one process extrusion to form the bushing The surface roughness and wall thickness; although this processing method has good economical and technological performance, and the on-site working environment has been greatly improved, it is not suitable for the processing technology of the front body connection bushing
