Problems solved by technology

[0007] 4. The hidden dangers of the product quality of the stabilizer bar are increased, and the product is easily deformed by heating and quenching
[0009] 1. Heating and quenching are carried out in intermediate frequency heating furnaces. At present, most intermediate frequency heating furnaces are imported and expensive;
[0010] 2. After the heating and quenching process, a tempering process is added. The tempering process takes a long time, about 1 hour; and the tempering temperature is high, about 400 ° C, which is a waste of money and energy

Embodiment 1

[0040] Select water-quenched steel wire as the raw material for the production of the stabilizer bar; blank the material according to appropriate requirements in the blanking machine; process the end on the punching machine; cold bend it into the designed shape in the cold bender; perform stress relief tempering in the tempering furnace ; The temperature of the tempering furnace is controlled at 150°C. The tempering time in the tempering furnace was controlled at 40 minutes. It is then cold-corrected in a cold-correction machine; finally it is surface-coated with powder to create the finished product.

Embodiment 2

[0042] Select water-quenched steel wire as the raw material for the production of the stabilizer bar; blank the material according to appropriate requirements in the blanking machine; process the end on the punching machine; cold bend it into the designed shape in the cold bender; perform stress relief tempering in the tempering furnace ; The temperature of the tempering furnace is controlled at 200°C. The time of tempering in the tempering furnace was controlled at 30 minutes. It is then cold-corrected in a cold-correction machine; finally it is surface-coated with powder to create the finished product.

Embodiment 3

[0044] Select water-quenched steel wire as the raw material for the production of the stabilizer bar; blank the material according to appropriate requirements in the blanking machine; process the end on the punching machine; cold bend it into the designed shape in the cold bender; perform stress relief tempering in the tempering furnace ; The temperature of the tempering furnace is controlled at 250°C. The tempering time in the tempering furnace was controlled at 40 minutes. It is then cold-corrected in a cold-correction machine; finally it is surface-coated with powder to create the finished product.

[0045] The present invention has the following advantages:

[0046] 1. The material has high dimensional accuracy. The diameter of the material can reach the tolerance requirement of ±0.1mm, and most of the existing materials are ±0.3mm.

[0047] 2. The surface quality of the material is high. There is no decarburized layer on the surface and no defects. No need for surfac...

Abstract

The invention discloses a method for manufacturing an automobile stabilizer bar, which is characterized by comprising the following steps: a. Selecting a quenched and tempered material as a raw material for producing the stabilizer bar; b. End processing; d. Cold bending in a cold bending machine; e. Stress relief and tempering in a tempering furnace, the temperature of the tempering furnace is 150 ℃ ~ 250 ℃, and the tempering time is 20 minutes ~ 40 minutes; f , Perform cold calibration in a cold calibration machine; g. Finally, use powder for surface coating. Since the quenched and tempered material is used to manufacture the automobile stabilizer bar, the stabilizer bar does not need quenching after forming, but only needs stress relief annealing, which reduces equipment investment, reduces production cost, shortens production cycle, and improves product quality and economy. benefit.

Description

technical field [0001] The invention relates to an automobile stabilizer bar and a manufacturing method thereof. Background technique [0002] At present, the main material of the domestic solid stabilizer bar is the material subject to quenching and tempering treatment. This type is mainly annealed and hot-rolled materials, such as hot-rolled steel, silicon-manganese steel, chrome-vanadium steel, chrome-silicon steel, etc. Its processing method steps are as follows figure 1 Shown: Raw material procurement → blanking in blanking machine → end processing on punching machine → cold bending in cold bender → heating and quenching in intermediate frequency heating furnace → tempering in tempering furnace → cold correction Cold correction in machine → final surface coating with powder. [0003] The use of materials subject to quenching and tempering has the following disadvantages: [0004] 1. The surface quality of the material is not high, which hinders the high performance ...
