Cold forming process of solid stabilizing rod

Abstract

The cold forming process of solid stabilizing rod includes the following steps: 1. end treatment of the solid rod material; 2. bending formation of the solid rod material at normal temperature; 3. heat treatment of the formed solid stabilizing rod; and 4. oil quenching treatment of the solid stabilizing rod. The step 1 may be also completed after the step 4. The cold forming process of solid stabilizing rod has short technological period, less surface decarburization, no overgrowth of the crystal grains and other advantages.

Description

technical field [0001] The invention relates to a cold forming process of a solid stabilizer bar. Background technique [0002] The stabilizer bar is an important part of the car, and its shape is complex, mostly three-dimensional. Stabilizer bars are divided into solid bars and hollow bars. The usual manufacturing process of the solid stabilizer bar is to use the hot forming process, that is, after the solid bar is heated to above 900°C, it is put into a special mold-forming machine, rapidly formed, and immediately oil quenched and tempered. Its technological process is as follows: [0003] Solid bar stock→end processing→medium frequency straight rod heating→forming with special forming machine→oil quenching and tempering. [0004] This processing technology has high production efficiency and is more suitable for large-volume, single-species production. However, due to the long heating time, the surface of the stabilizer bar is obviously decarburized, and the grains of ...
