Tension spring machining is a common metalworking process used to make the elastic element of a tension spring. Tension springs are usually used in automobiles, home appliances, mechanical equipment and other fields, playing the role of connection, support, cushioning, transmission of force and so on. In the process of tension spring processing, it needs to go through a series of processes such as material selection, coiling, heat treatment, surface treatment and so on, in order to produce qualified tension spring products.

First of all, the first step in the processing of tension springs is to choose the right material. Generally speaking, the commonly used materials for tension springs include carbon steel, stainless steel, alloy steel, etc. It is very important to choose the right material according to different needs and environmental conditions. At the same time, the quality and performance of the material will also directly affect the service life and performance of the tension spring.

Next is the coiling process, mainly including bending, coiling, stretching and other steps. In the coiling process, it is necessary to process the precise size and shape according to the design requirements of the product to ensure that the tension spring can work properly. At the same time, coiling also needs to consider the strength and hardness of the material to avoid problems such as fracture or deformation.

Heat treatment is a very important part of the processing of tension springs, through heat treatment can change the organizational structure and properties of the spring, improve its hardness and strength. Common heat treatment methods include tempering, annealing, quenching, etc. It is very critical to choose the appropriate heat treatment process according to different requirements.

Then, the surface treatment is the end of the spring processing process, through the surface treatment can improve the corrosion resistance of the spring and the appearance of the quality. Common surface treatment methods include spraying, plating, galvanizing, etc., according to the product's use of the environment and requirements to choose the appropriate surface treatment method.

Overall, the processing of tension springs is a technology-intensive metal processing technology, which requires a number of procedures to complete. Only by mastering the appropriate material selection, processing technology and quality control methods, can we produce high-quality tension spring products. We hope that through continuous technical research and practice, we can better apply the technology of tensile spring processing to meet the market demand.
