Profiled spring Compression spring (compression spring) is to withstand the pressure of the spiral spring, which is used in the cross-section of the material is mostly circular, but also useful rectangular and multi-strand steel hanging roll, the spring is generally equal pitch, the shape of the compression spring are: Cylindrical, conical, convex and concave and a small number of non-circular and so on, the compression spring ring and the ring there is a certain gap between when under external load when the spring shrinkage deformation, storage deformation energy.
Spring is a mechanical part that uses elasticity to work. The parts made of elastic material are deformed under the action of external force, and they are restored to the original shape after removing external force. Also as "spring." Generally made of spring steel. Complex and diverse types of springs, divided by shape, the main spiral spring, scroll springs, leaf springs, shaped springs.
According to the nature of the force, the spring can be divided into tensile spring, compression spring, torsion spring and bending spring, according to the shape can be divided into disc springs, ring springs, leaf springs, coil springs, truncated cone spiral springs and torsion bar springs , According to the production process can be divided into cold coil spring and hot coil spring. Ordinary cylindrical springs due to the manufacture of simple, and can be made according to the load situation of various types, simple structure, so the most widely used. Spring manufacturing materials in general should have a high elastic limit, fatigue limit, impact toughness and good heat treatment properties, commonly used carbon spring steel, alloy spring steel, stainless steel spring and copper alloy, nickel alloy and rubber Wait. Spring manufacturing methods are cold roll method and hot roll method. Spring wire diameter less than 8 mm generally used cold roll method, more than 8 mm with the hot roll method. Some of the springs are also pressed or shot peeing after they are made to increase the load carrying capacity of the spring.
The role of the spring 1: cushioning and damping, such as crusher support spring.
2: play the role of energy storage, such as the spring above the clock.
3: Control motion. Springs such as valves, clutches, brakes, and various regulators.
4: Force measuring device.
5. Precise adjustment performance. The relationship between force and displacement is very sensitive;
6.Soft performance is good, that is, the scope of deformation is relatively wide;
Made easier
7. The structure is more compact;
8. High energy rates
Spring is a kind of good elastic parts, it has the characteristics of deformation, flexibility and so on. Within the limits of the spring, its spring force is proportional to the amount of spring elongation, following Hooke's law, F = KX, and the following applies to the spring:
1, To ease the impact and absorb vibration: This kind of spring has a large elastic deformation capacity, can absorb vibration and impact. Such as cars, trains in the buffer spring, coupling vibration springs and so on.
2, The control body movements: Such springs require little change in the force within a certain range of deformation. Such as a valve spring in an internal combustion engine, a control spring in a clutch, a spring in an automatic machine cam mechanism, and the like.
3, Storage of energy: This type of spring requires both greater flexibility, but also requires a more stable force. Such as the clock spring, bolt spring, automatic machine tool holder automatically return spring in the device and so on.
4, The size of the force measurement: This type of spring requires a linear relationship between its force and deformation. Such as dynamometer and spring balance in the spring and so on. Many types of springs, according to the different load can be divided into tensile springs, compression springs, torsion springs and bending springs. According to the different spring shape can be divided into: coil spring, butterfly spring, ring spring, coil spring, plate spring.
