In mechanical and electrical products, a wide range of springs, mainly in the following types.
1) to cars, motorcycles, diesel engines and gasoline-based matching spring and spring. Such springs have valve springs, suspension springs, damping springs and clutch springs, etc., a larger amount, accounting for about 50% of spring production. While the technical level is also high, it can be said that the technical level of these springs are representative, they are mainly to the high fatigue life and high resistance to relaxation of the direction of development, thereby reducing the quality.
2) railway locomotives, trucks and construction machinery consisting mainly of large springs and leaf springs, these springs to hot roll forming the main spring manufacturing is an important aspect. With the development of high-speed railway, vehicle suspension system upgrade, as the vehicle suspension thermoforming spring technology has greatly improved, this kind of spring mainly to high strength and high precision direction of development to stabilize product quality.
3) to instrument and electronic-based electrical spring, the typical products such as motor brush springs, switch springs, cameras and camera springs, and computer accessories spring, instrument accessories spring. Such springs in the film spring, the opposite sex accounted for a larger proportion of the spring, different products on the material and technical requirements vary widely. This kind of spring is mainly toward both high strength and small-scale direction.
4) to the daily use of machinery and electrical appliances mainly metal springs, such as mattresses, sofas, door hinges, toys, lighters, such spring demand, but the technical content is not high, to small enterprises to improve the development of the spring Opportunities, this type of spring is mainly to the direction of miniaturization.
5) to meet the special needs of special springs, such as textile machinery with cradle spring, requires a high anti-relaxation properties; ladle with a spring, requiring high heat resistance; mine vibration screen with suspension springs, Not only requires a high fatigue performance, but also requires a high corrosion resistance, and thus the use of rubber composite metal spring: in order to meet the vehicle driving comfort, the use of air springs.
For the present cross-section suspension springs and spring springs, from the lightweight, space-saving, improve comfort and improve the spring stress distribution than the circular cross-section spring is more reasonable, but this kind of spring material prices are high, the spring manufacturing process complexity , So that the spring cost is higher than the circular cross-section spring. So now do not see the opposite section of the spring to replace the circular cross-section spring signs.
