Problems solved by technology

Since the hollow stabilizer bar is made of a hollow metal tube, its strength is lower than that of a solid bar in the same shape, so the manufacturing process of the above-mentioned solid stabilizer bar is completely inapplicable to the manufacture of a hollow stabilizer bar, making the production of a qualified hollow stabilizer bar a new subject.

Embodiment Construction

[0039] see figure 2 . The manufacturing process of the automobile hollow stabilizer bar of the present invention includes: blanking step 201 → raw material cold bending forming step 202 → quenching step 203 → tempering step 204 → rough repair and cold correction step 205 → end processing step 206 → grinding step 207 → finishing Cooling correction step 208 → shot peening step 209 → painting step 210 .

[0040] Below in conjunction with the specific embodiment of producing a kind of hollow stabilizer bar further illustrate characteristic performance of the present invention:

[0041] Blanking step 201: first select qualified raw materials, and cut the qualified hollow metal pipes into stabilizer bar single material according to the model specification of the stabilizer bar. When selecting raw materials, select low-carbon steel materials suitable for manufacturing hollow stabilizer bars. For example, the present embodiment takes the hollow stabilizer bars used on Chevrolet Cru...

Abstract

The invention relates to a manufacturing process of a hollow stabilizer rod of an automobile, which comprises the blanking step, the step of cold bending and molding of raw materials, the quenching step, the tempering step, the step of rough trimming and cold straightening, the step of end processing, the step of fine trimming and cold straightening, the shot blasting step, and the coating step. By adopting the manufacturing process, the molding speed and the molding quality of the stabilizer rod can be improved. The depth of a decarburization layer on the surface of the stabilizer rod is reduced, and the fatigue life is prolonged. Cracks can be prevented after quenching the stabilizer rod. Compared with a solid stabilizer rod, the hollow stabilizer rod manufactured by adopting the manufacturing process is light in weight, has smooth and clean surface of the stabilizer rod and has no phenomena of orange peels, accumulation and exposure, and technical indexes completely achieve the requirements of automobile parts.

Description

technical field [0001] The invention relates to a manufacturing process of an automobile hollow stabilizer bar. Background technique [0002] The stabilizer bar is an important part of the car suspension system. Its characteristic is to improve the ride comfort and reduce the shaking when the car turns. In the prior art, the stabilizer bar is generally made of solid metal material, so it is called a solid stabilizer bar. Existing manufacturing processes for solid stabilizer bars (see figure 1 ) includes: blanking step 101 of selecting a solid metal material for blanking → end heating and forming step 102 → stabilizer shaft heating and forming step 103 of the stabilizer shaft formed after overall heating → oil cooling quenching step 104 → box tempering furnace Tempering step 105 → cold correction step 106 → grinding step 107 → primary shot peening step 108 → painting step 109 . [0003] In recent years, with the gradual strengthening of people's awareness of energy saving ...
