Problems solved by technology

General manufacturers in the industry just spray the anti-rust paint directly or without shot-peening during surface treatment, and then paint the black paint after the anti-rust paint is dry. This kind of coating has poor corrosion resistance, short service life and potential safety hazards.

Embodiment Construction

[0011] Steps:

[0012] 1. Unloading: Unloading on the sawing machine.

[0013] 2. Bending: Heating to 950±50°C in a diesel local heating furnace, and bending into a U shape with a hydraulic bending machine.

[0014] 3. Forging: use 300T and 400T friction presses and 125T punches.

[0015] First place the U-shaped workpiece in an intermediate frequency heating furnace and heat it to 1150-1200°C. Install the upper mold on the friction press, lock the heated workpiece on the lower mold, perform the first upsetting, then quickly replace the upper mold, and perform the second upsetting. Finally, the workpiece with a temperature of 1000°C-1050°C is taken from the lower mold for end forming.

[0016] 4. Drilling and reaming: Draw a line with a height gauge to ensure coaxiality, and use a drilling machine and a milling machine to drill and enlarge holes.

[0017] 5. Boring: use a professional boring machine to bore the end hole to the size required by the drawing.

[0018] 6. Que...

Abstract

The invention discloses a method for producing a vehicle-used stabilizer bar with high corrosion resistance, which relates to the processing technology field of metal parts, in particular to a production process of an automotive stabilizer bar. The production process comprises the following steps: blanking, bending, forging, drilling and reaming, boring, quenching and tempering, correcting, rotoblasting, phosphating, surface plastic-spraying and finally pressing into a bushing. Through the process, the corrosion resistance of the surface of the stabilizer bar is effectively improved and the service life is also prolonged. After the corrosion resistance test of 150 hours is carried out according to the method in QC/T484-1999, the spread of unilateral corrosion along the cutting does not exceed 2 mm and the check result shows that the unilateral corrosion is 1.3 mm.

Description

technical field [0001] The invention relates to the technical field of processing metal parts, in particular to the production technology of an automobile stabilizer bar. Background technique [0002] As an important part of automobile suspension components, the stabilizer bar can improve the roll stiffness of the suspension and adjust the ratio of the roll stiffness of the front and rear suspensions to ensure that the car has good driving stability, thereby ensuring the safety, comfort and smoothness of the car. sex. General manufacturers in the industry just spray-peen or directly apply anti-rust paint without shot-peening during surface treatment, and then paint black paint after the anti-rust paint is dry. This coating has poor corrosion resistance, short service life, and potential safety hazards. Contents of the invention [0003] The object of the present invention is to provide a production method of a stabilizer bar with high corrosion resistance and long service...
