Automotive spring steel hardness _ spring _ classification with the rapid development of auto industry, auto spring already widely used in automobile manufacturing, also known as "car trunk play yellow, tensile spring" general installation in fixed on a chain, then hold down the key controller of trunk unlock key will be fully automatic and play a certain Angle, has the strong point of the work Yes, so what is the manufacturing process of the car spring? Let's find out.

The production and manufacturing process of automobile spring:

1. The spring coil with high in-situ stress of stainless steel wire with compressive strength of 200Mpa was made into the dimension shape of the electric tail door.

2. Then embed the dimension shape of the electric tail door in the natural environment of 430~460℃ to carry out heat insulation for 40 minutes;

3. Carry out the thermal shutdown brake immediately on the electric tail door after heat insulation;

4. The spring steel with high in-situ stress is de-stressed and quenched after production, and then the elastic yellow after heat insulation is immediately put on the heat shutdown brake, so as to reasonably improve the anti-attenuation coefficient working ability of the commodity.
