Tension spring, also called tension spring or simply tension spring, is a coil spring that bears axial tension. When this kind of spring is not under load, the rings are generally tight and there is no gap. The working principle of the tension spring is mainly to use the elastic deformation of the material to achieve the effect of elastic force, thereby changing the position of the components of the mechanical device or restoring it to its original state. When a tension spring is acted upon by an external force, its dimensions such as length and diameter will change. However, due to the elasticity of its material, the spring can return to its original length and shape when the external force disappears.
The main application areas of tension springs are very wide, including medical respiratory equipment, motion control, medical mobile equipment, home care equipment, shock absorption, pump springs, mechanical and electronic protective hardware, fluid control valves, mechanical aerospace components, actuators , switch equipment, etc. In addition, it also has important applications in the fields of national defense, marine, computers, electronics, cars, molds, medicine, biochemistry, aerospace, railways, nuclear power, wind power, thermal power, engineering machinery, mining machinery, construction machinery, elevators and other fields.
When manufacturing tension springs, material selection is a very critical step. Common materials include high carbon steel wire (suitable for occasions that need to withstand large pressure), stainless steel wire (suitable for complex environments, with excellent corrosion resistance), copper wire (soft and wear-resistant, suitable for occasions that require forced bending) And alloy steel wire (suitable for occasions with high mechanical operation speed). There are many methods of making springs, such as winding, pressing and drawing. Spring processing steps may include stabilization to ensure that the spring maintains the desired shape.
To sum up, tension springs play an important role in many industries such as machinery, electronics, medical care, and transportation due to their excellent performance and wide range of applications.
