With the rapid development of the automotive manufacturing industry, car tailgate springs have long been widely used in the automotive manufacturing industry, commonly known as "car trunk spring" or "stretch spring". They are usually installed on a fixed chain, and when the controller key and trunk unlock button are pressed, they will automatically spring up to a certain angle, providing support points. So, how should car tailgate springs be made? Below, Dongguan Yipin Spring Manufacturer will take everyone to learn about it together.

1、 Production and manufacturing steps of car tailgate springs

(1) Using a multi axis CNC machine tool spring press, a high stress spring steel coil with a compressive strength of 200Mpa made of stainless steel wire is transformed into an electric tailgate spring shape;

(2) Further embed the electric tailgate in a natural environment of 430-460 ℃ for insulation and heat preservation for 40 minutes;

(3) Immediately implement a thermal cut-off brake on the electrically operated tailgate that has been insulated and yellowed;

(4) After producing high stress spring steel and quenching it to remove the stress, the thermal insulation and insulation of the spring yellow were immediately subjected to thermal air brake, thereby reasonably improving the anti attenuation coefficient working ability of the product,

Working characteristics: Springs can produce significant elastic deformation under external forces and are widely used as elastic components in mechanical equipment.

Function:

1) Control the movement of mechanisms or the position of components;

2) Buffer absorption; (such as vehicle springs and springs for various buffers)

3) Energy storage; (such as springs in clock instruments)

4) Measure the magnitude of force; (such as the spring in the spring scale)

5) Change the natural frequency of the system;

Category:

1) Spiral spring: divided by shape: cylindrical, truncated cone

Divided by load: tension spring, compression spring, torsion spring

2) Circular spring

3) Butterfly spring

4) Flat spiral spring

5) Plate spring
