Do you know the spring?

A spring is a mechanical part that uses elasticity to work.

Stainless Steel Rectangular Breather Spring

Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. Also known as "spring".

Generally made of spring steel.

There are various types of springs.

According to the nature of the force, springs can be divided into tension springs, compression springs, torsion springs and bending springs;

According to the shape, it can be divided into disc spring, ring spring, leaf spring, coil spring, truncated cone scroll spring and torsion bar spring, etc.;

According to the production process, it can be divided into cold coil spring and hot coil spring.

Ordinary cylindrical springs are the most widely used because they are simple to manufacture and can be made into various types according to the loading conditions.

Spring manufacturing materials should generally have high elastic limit, fatigue limit, impact toughness and good heat treatment performance, etc.;

Carbon spring steel, alloy spring steel, stainless spring steel, copper alloy, nickel alloy and rubber are commonly used.

Spring manufacturing methods include cold rolling and hot rolling.

The spring wire with a diameter less than 8 mm generally uses the cold rolling method, and the spring wire with a diameter greater than 8 mm uses the hot rolling method. Some spring also will be suppressed or shot blast after making, and the bearing capacity of spring will be improved.

As an important component in the industrial system, the spring has a large amount of use, and there are various types. Therefore, the production of the spring is gradually automated from the original manual production.

Ninety years ago in China, the spring industry had only a few mechanical equipment specializing in the production of springs;

As the spring market is getting bigger and bigger, gradually professional spring equipment companies have also entered China,

The spring has many functions, such as measuring function, resetting function, driving function, buffering function, sounding function, pressing function, etc.


Spring is an elastic element widely used in mechanical and electronic industries;

When the spring is loaded, it can produce a large elastic deformation, which converts mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the spring disappears and returns to its original shape, and the deformation energy is converted into mechanical work or kinetic energy.
