Two Methods for Manufacturers to Harden Compression Springs

The two ends are open, closed, or flattened or ground, and their shapes are diverse. When subjected to external loads, they will shorten deformation and transform into variable functions. Compression springs can be applied in multiple fields, such as electronics, computers, cars, compressors, and other professions, highlighting their effectiveness.

Compression Spring is a hardware accessory composed of several spiral shapes formed by lines, making it more difficult to stiffen and strengthen than flat hardware fittings. In addition, the stiffening effect of the compression spring section is strictly controlled to fully resist the fatigue and cracking resistance of the pressure reducing spring after use.

The pressure spring undergoes shot peening and heat treatment hardening. Shot blasting and hard spring processing require the processing of multiple pressure springs, which can be transported to the explosion chamber through a separate belt conveyor through the pressure springs. The shot blasting city is equipped with a set of parallel rods to strengthen the rolling and compression of the drum together. The spring side rotates forward, allowing the projectile to circulate overvoltage between the various Coil Springs through high-speed rotation, hitting the surface of the metal ring, which is the most important part of the pressure spring stress. Shot peening is one of the best strengthening methods for S. The tension and high stress fatigue life of the spring can advance by more than four times after appropriate shot peening.

After the compression spring is hardened, the application effect of the spring will be improved, especially after a period of use, the spring needs to be hardened and continued to be used, effectively extending the service life of the spring.

Compression spring parameters:

Formula:

The meaning represented by each term in the above formula is:

G=shear modulus of elasticity [MPa] (G values range from 80000 for carbon steel to 72000 for stainless steel)

D=wire diameter [mm, in]

N=number of useful circles [-]

D=center diameter [mm, in]

K=spring coefficient [N/mm, lb/in]

This formula is the calculation formula for spring stiffness, and the stiffness multiplied by the operating stroke is equal to the operating force of this spring.

Through the above equation, we can conclude that the parameters of the compression spring must be composed of: data, wire diameter, center diameter, number of useful coils, total length of the spring, operating height, and required force. If there is no special requirement for the strength of the spring, the parameters of the working height and required strength of the spring can be omitted.

Compression spring application:

The steel Wire Spring of compression spring is used for all types from household appliances to motor equipment, motors, etc., as it is the required type of spring. The effect of the load on them or their ends is compressed, and the compression spring is compressed. The planning of the wire attempts to return the spring to its original shape, and then the load is pushed back.

Primary usage directions: medical respiratory equipment, medical mobile equipment, handicrafts, home care equipment, shock absorbers, engine valve springs.
