Characteristics of compression spring
Compression spring? Provide the ability to resist external pressure. Generally, compression springs are wires wound at equal intervals and have a fixed wire diameter. Compression springs use multiple open coils to resist external pressure (such as gravity pressing on wheels or body pressing on mattresses). That is, they push back to resist external pressure. Generally, compression springs are wires wound at equal intervals and have a fixed wire diameter. In addition, there are conical compression springs, or a combination of conical and linear springs. According to different application fields, compression springs can be used to resist pressure and/or store energy. Circular steel wire is the most commonly used compression spring, but there are also compression springs made of square, rectangular and special-shaped steel wire.
Compression spring (compression spring) is a spiral spring that bears axial pressure. The cross section of the material it uses is mostly round, right? It is made of rectangular multi-strand steel coils, and the springs are generally of equal pitch. The shapes of compression springs are: cylindrical, conical, convex-concave and a small number of non-circular. There is a certain gap between the coils of the compression spring. When subjected to an external load, the spring contracts and deforms to store deformation energy.

The common springs in our life are: tension coil spring, compression coil spring and torsion coil spring. Among them, the number of tension and compression springs is relatively large, and the specifications are complicated, so it can be modified slightly when using. If the number of springs used is small, it is easy to buy in the market, but the price is relatively high. Generally, a large number of long-term use will find professional manufacturers to supply. Whether it is used in a small amount or in a large amount, the standard of compression spring can not be ignored.
