Spring in the classification of mechanical and electrical products

In mechanical and electrical products, there are many types of springs, mainly the following types.

1) Matching springs and springs for automobiles, motorcycles, diesel engines and gasoline engines. This kind of spring has valve spring, suspension spring, shock absorber spring and clutch spring, etc., the amount is large, accounting for about 50% of the spring production. At the same time, the technical level is also high, it can be said that the technical level of these springs is representative, they are mainly to the direction of high fatigue life and high anti-relaxation, so as to reduce the quality.

2) Large springs and plate springs based on railway rolling stock, truck and construction machinery, these springs are mainly hot roll forming, which is an important aspect of the spring manufacturing industry. With the development of high-speed railway and the upgrade of vehicle shock absorption system, the thermoforming spring technology as a vehicle suspension has been greatly improved, and this kind of spring is mainly developed in the direction of high strength and high precision to stabilize product quality.

3) Electronic and electrical springs based on instruments, typical products such as motor brush springs, switch springs, cameras and camera springs, as well as computer parts springs, instrument parts springs, etc. In this kind of spring, the blade spring and the opposite sex spring account for a large proportion, and the material and technical requirements of different products are different. This type of spring is mainly developed in the direction of both high strength and miniaturization.

4) Hardware springs based on daily machinery and electrical appliances, such as mattresses, sofas, door hinges, toys, lighters, etc., such springs are in large demand, but the technical content is not high, which improves the development opportunity for small spring enterprises, and such springs are mainly developed in the direction of miniaturization.

5) Special springs based on special needs, such as shaking frame springs for textile machinery, require high anti-relaxation performance; Spring for ladle water slide, requiring high heat resistance; The suspension spring for the mining vibrating screen not only requires high fatigue performance, but also requires high corrosion resistance, so the rubber metal composite spring is used: in order to meet the comfort of the vehicle when driving, the air spring is used.

For the existing suspension springs and valve springs of the opposite section, the consideration of lightweight, space saving, improving comfort and improving the spring stress distribution is more reasonable than the circular section spring, but the high price of such spring materials and the complex spring manufacturing process make the spring cost higher than the circular section spring. Therefore, there is no sign that the opposite-section spring replaces the circular section spring.
