Problems solved by technology

The suspension arm currently in use is welded by multiple sections of steel pipes of different shapes. During production, this suspension arm needs to be welded many times around the outer circumference of the steel pipe. Not only is the process complicated, but the processing personnel have a large amount of labor and the processing time is long. , and seriously affect the quality of the suspension arm

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] Such as figure 1 Shown, a kind of automobile chassis suspension arm molding process comprises the following steps:

[0035] (1) Blanking: Put the flat steel plate into the mold for stamping and drawing. During the drawing process, the thinning rate of the steel plate is controlled at 18~22%. If the thinning rate is too high or too low, the steel plate will crack. Wrinkles affect the service quality of the suspension arm, and trim the steel plate after stamping and drawing;

[0036] (2), Punch positioning hole 4;

[0037] (3) Half-circle cut on the end face: cut a semi-circular groove 3 on one of the end faces, and trim the groove 3;

[0038] (4) Flip the two sides of the steel plate so that the two sides are close to each other;

[0039] (5) Rounding: the steel plate after flanging is rounded and formed with a rounding forming mold, and a gap...

Abstract

The invention discloses an automotive chassis suspension arm molding technology which comprises the following steps of (1) blanking, (2) positioning hole punching, (3) semicircle cutting on the end face, (4) flanging, (5) edge rolling, (6) shaping, (7) welding, (8) semicircle cutting, (9) cutting again, (10) punching, (11) end face milling, and (12) manual burr removal. A suspension arm obtained through the above molding technology only needs welding one time, repeated welding is not needed, the labor amount of machining persons is greatly reduced, and meanwhile, the using quality of the suspension arm is improved.

Description

technical field [0001] The invention relates to a molding process of an automobile chassis suspension arm. Background technique [0002] The suspension arm is an important part of the chassis suspension system of the car. It connects the (front or rear) wheel support of the car to the body of the vehicle or fixes it on the bracket of the car body. It needs to have certain fatigue resistance, rigidity and Extensibility. The suspension arm currently in use is welded by multiple sections of steel pipes of different shapes. During production, this suspension arm needs to be welded many times around the outer circumference of the steel pipe. Not only is the process complicated, but the processing personnel have a large amount of labor and the processing time is long. , and seriously affect the quality of use of the suspension arm. Contents of the invention [0003] In order to solve the above-mentioned deficiencies in the prior art, the object of the present invention is to p...
