The compression spring (compression spring) is a coil spring that is subjected to the pressure. The material used is mostly circular in cross section. It is also rolled with a rectangular and multi-strand steel. The spring is generally of equal pitch. The shape of the compression spring is: Cylindrical, conical, convex and concave, and a small number of non-circular, etc., there is a certain gap between the ring of the compression spring and the ring. When subjected to external load, the spring shrinks and deforms to store deformation energy.
Compression Springs provide resistance to external loads. The compression spring is generally a coiled wire such as a wire and has a fixed wire diameter. The compression spring uses a plurality of open coils to provide resistance to external loads (such as gravity pressing the wheel or the body pressing against the mattress). That is, they push back to resist external pressure. The compression spring is generally a coiled wire such as a wire and has a fixed wire diameter. In addition, there are also conical compression springs, or a combination of conical and linear springs. Depending on the field of application, compression springs can be used to resist pressure and/or store energy. Circular wire is the most commonly used compression spring, but there are also compression springs made of square, rectangular and special shaped wire.
