As a common elastic element, double ear tension spring plays a key role in many fields, and its production process has a profound impact on performance.
The selection of raw materials is the basic link of the production process and plays a decisive role in the performance of double ear tension spring. High-quality materials such as high-strength alloy steel and stainless steel have good elasticity and toughness and can withstand large tension and stress. If poor-quality materials are selected, the elastic modulus, yield strength and other performance indicators of the tension spring will be greatly reduced, and it is easy to deform or even break when subjected to external force, which seriously affects its service life and reliability.
In the wire preparation stage, the cold drawing process can improve the strength and hardness of the steel wire. The steel wire is stretched into the desired shape by cold working, so that the internal grain of the steel wire is refined and the organizational structure is denser, thereby enhancing the mechanical properties of the tension spring. However, excessive cold drawing may cause defects such as cracks in the steel wire, reducing the quality of the tension spring.
The winding process is also critical. During the winding process, the operator needs to accurately control parameters such as winding speed and tension. If the winding speed is too fast or the tension is uneven, the shape and size of the tension spring will deviate, resulting in uneven force, affecting elasticity and stability. In addition, the choice of winding method, such as dense winding or loose winding, will also affect the performance of the tension spring. The dense winding structure can provide greater rigidity and is suitable for occasions with high elasticity requirements; the loose winding structure has better buffering performance and is suitable for scenes that need to absorb impact energy.
Heat treatment is an important part of the production process of double ear tension spring. The organizational structure and properties of the material can be adjusted through heat treatment processes such as quenching and tempering. Quenching can make the tension spring have high strength and hardness, but if the quenching temperature and time are not properly controlled, it will cause problems such as cracks and deformation in the tension spring. Tempering can increase the toughness and plasticity of the tension spring, eliminate the internal stress generated by quenching, and improve its fatigue resistance. Reasonable heat treatment process can make the tension spring have good toughness and elasticity while ensuring strength.
Surface treatment can not only improve the corrosion resistance and aesthetics of the tension spring, but also affect its performance to a certain extent. For example, galvanizing can form a protective film on the surface of the tension spring to prevent it from corrosion and extend its service life; spraying can improve the surface hardness of the tension spring and reduce friction and wear.
The production process of double ear tension spring covers multiple links, each of which has an important impact on the performance of the tension spring. Only by strictly controlling each link of the production process, selecting high-quality materials, and accurately operating various process parameters can we produce double ear tension springs with excellent performance and reliable quality to meet the use needs of different fields.
