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

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0020] Example.

[0021] see figure 1 , the processing technology of the front body connection bushing in this embodiment, which makes full use of cold extrusion and lathe processing, the steps are as follows: (1) blanking: the raw material is wire rod, and the φ36 material is drawn to φ35 and blanked by a cold heading machine; (2) Hot forging: the material is hot forged, and the φ35 is hot forged into a special-shaped blank to prepare for the punching and punching forming sequence; (3) punching and forming: specific punches, dies, die cores, etc., composite cold Extrusion hot forging billet, because the pre-order adopts hot forging forming, the inner and outer coaxiality can reach within φ0.2; the extruded shape o...

Abstract

The invention relates to a front car body connecting bush machining process, and belongs to the field of automobile accessory production and manufacturing. The process comprises the steps of blanking,hot forging forming, stretching hole forming, turning machining and drilling. The process is simple and reasonable, the product size is stable, the material mechanical property is good, the production efficiency is high, and universal performance is realized; and a series of bushes with different specifications can be machined by adjusting the mold and the program, and the use requirements can bemet.

Description

technical field [0001] The invention relates to a process, in particular to a process for processing a connecting bush of a front body, which is suitable for mass production and belongs to the field of auto parts production and manufacture. 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 processing method for a bushing". The processing method of th...
