There are many kinds of springs in our daily life, including tension spring, torsion spring, compression spring, leaf spring, battery spring, etc. Springs are mechanical parts that use elastic and structural characteristics to produce deformation when working. Transforming deformation energy into mechanical energy, compression spring is the most used one among all springs.

1、 Concept of compression spring

Compression spring is a kind of commonly used spring, which is also called "pressure spring" and belongs to spiral spring. The cross section of the materials used is mostly circular, which is also rolled from rectangular and multi-strand steel. The spring is generally of the equal pitch. The shape of the compression spring is cylindrical, conical, convex-concave and a small amount of non-circular. There is a certain gap between the rings of the compression spring, and the spring shrinks and deforms under the action of an external force to store deformation energy.

It is different from the extension spring in that it has a hook or a pull ring at both ends. For example, the rings at both ends are compression springs and the pull ring is extension springs, which is the difference between the two.

The compression spring is provided with the pressure to resist the spring by external pressure. When the spring load is compressed, the spring will become shorter, then resist the load, and finally return to the original length. It is a mechanical component that can effectively store energy. Compression springs are divided into cylindrical, conical, concave, convex, and rectangular compression springs in shape. A cylindrical compression spring is the most widely used spring, but other springs with different shapes are also used in different fields. Common compression spring materials include carbon spring wire, harp spring wire, and stainless steel spring wire.

1. Carbon spring steel wire: high-quality carbon steel wire, cold drawn and hardened, and lead wire is isothermal quenched. It has the characteristics of low plasticity, strong elasticity, and strong strain resistance. It is widely used in mattresses, automobile cushions, machinery manufacturing, stationery, electric tools, electrical equipment, and other industries.
2. Harp spring wire: It is made of a piano steel wire plate. After being quenched by lead at room temperature, it has a very high elastic limit and strength limit. It is widely used as a material for small springs. The safety valve is used for this compression spring;
3. Stainless steel spring wire: after quenching and tempering, stainless steel spring wire can be used as a spring with high-temperature resistance, corrosion resistance, and non-magnetic strength in the working environment specified in the fields of chemical machinery and electronic instruments.

2、 Characteristics of compression spring

The compression spring provides resistance to external load pressure. Compression springs are usually wire wound at equal intervals and have a fixed wire diameter. Compression springs use multiple open coils to resist the pressure of external loads, such as gravity on the wheel, or your body against the mattress. In other words, they resist external pressure. Compression springs are usually wire wound at equal intervals and have a fixed wire diameter. In addition, there are conical compression springs or combinations of conical and linear springs. Depending on the field of application, compression springs can be used to resist pressure and store energy. The round line is a compression spring commonly used by Z, but there are also compression springs made of square, rectangular, and special shaped lines.

3、 Application of compression spring

The wire spring used for compression spring is used in all fields from household appliances to motor equipment, motors, etc. because it is the required spring type. Compression springs are designed as compression lines to attempt to restore the springs to their original shape by acting on them or the compressed load at their ends, thereby pushing the load back. Main application directions: medical respiratory equipment, medical mobile equipment, hand tools, home care equipment, shock absorption, and engine valve spring.

The application range of compression springs is very wide, mainly in industries such as automobiles, lasers, medical equipment, etc. Different industries and fields require different materials, sizes, and processing technologies for compression springs, and you should be very careful when selecting compression springs. Therefore, it is helpful to have a deep understanding of the relevant knowledge of compression springs to help you choose!
