Compression spring is a kind of spiral spring which withstands the pressure. Its material cross section is mostly circular, and it is also made of rectangular and multi strand steel. The circumferential spring is usually of equal pitch. The format of compression spring is cylindrical, conical, convex and concave, and a small amount of noncircular, etc. There is a certain gap between the coils of the compression spring. When it is subjected to external load, the spring will shrink and deform, and the deformation energy will be stored.
A spiral spring made of spring wire. There are many types of spiral spring, which can be divided into ordinary cylindrical spiral spring and variable diameter spiral spring according to its appearance; it can be divided into left-hand metal spring and right-hand rotation spring according to the helix direction. Cylindrical coil spring layout is simple, Easy to manufacture, all information network new 2. It can be used as compression spring, tension spring and torsion spring. When the load is large and the radial dimension is unlimited, two compression springs with different diameters can be used together to form a combined spring. There are taper coil spring, volute coil spring and concave spiral spring.
The conical spiral spring has good cushioning performance and can withstand large load. Volute spiral spring can store more energy and bear larger load. But the manufacturing process is relatively large. The performance of concave spiral spring is similar to that of conical spiral spring, which is mostly used for cushion and mattress. The load surface of spring steel wire includes circle and rectangle, and circular section is the most commonly used.
The coil spring, that is, the torsion spring, is a kind of spring subjected to twisting and folding, and its task limitation is also tightly wound into a spiral shape. The end layout of torsion spring is made into torsion arm in various formats, not hook ring. Torsion spring is commonly used in mechanical equalizing mechanism. It is widely used in automobile, machine tools, electrical appliances and other industrial production.
