Five common spring classifications

1. Hardware springs include daily-use machinery and electrical appliances, such as mattresses, sofas, door hinges, lighters, etc. These types of springs are in high demand, but the technical content is not high, which provides small spring companies with increased development opportunities. The spring is mainly developed in the direction of miniaturization.　　2, large springs and leaf springs 　　 include railway rolling stock, trucks and construction machinery. These springs are mainly formed by hot coils, which is an important aspect of the spring manufacturing industry. With the development of high-speed railways and the upgrading of vehicle damping systems, the technology of hot-formed springs as vehicle suspensions has been greatly improved. This type of springs are mainly developed in the direction of high strength and high precision to stabilize product quality.　　3, matching spring 　　 includes matching springs in automobiles, motorcycles, diesel engines and gasoline engines. Such springs include valve springs, suspension springs, damping springs and clutch springs, etc., and they are used in large quantities, accounting for about 50% of the spring production. At the same time, there are many kinds of springs in electromechanical products.　　4. Electronic and electrical springs　　 are generally based on instruments and meters. Typical products include motor brush springs, switch springs, camcorders and camera springs, as well as computer accessories springs, instrumentation accessories springs, etc. In this type of springs, leaf springs and heterosexual springs account for a larger proportion, and different products have large differences in material and technical requirements. This type of spring is mainly developed in the direction of both high strength and miniaturization. 5. Special springs mainly meet special needs, such as cradle springs for textile machinery, which require high relaxation resistance; springs for ladle water slides, which require high heat resistance; suspension springs for mine vibrating screens, not only requirements It has high fatigue performance and requires high corrosion resistance, so rubber-metal composite springs are used: in order to meet the comfort of the vehicle when driving, air springs are used.
