Devolopment of Spring Design, Material and Processing Technology
Introduction
Springs are a type of mechanical component widely used in various applications, such as automobile parts and engineering machines. As such, the design, choice of material and processing technology of springs not only affects the performance of products, but also directly influences the cost. To satisfy the application requirements, in recent years efficient design of springs is combined with material selection and processing technology in an integrated manner, which has continuously promoted the development of spring design technologies.
Design of Spring
Spring design is the process of using mechanical principles to create a spring with the desired characteristics and performance. The design of a spring usually begins with a basic understanding of the intended application and use of the spring. This allows the designer to choose a suitable shape, material, and processing technology. The principle of the design of springs includes that the characteristics of the spring are expressed as a function of its component size. That is, the size, shape and deflection of the spring are determined by the design force, which is applied to the component and expressed in stress or load. Apart from this, creative designs are also needed in order to reduce resonance and reduce component weight.
Selection of Materials
The choice of materials used in spring design is very important and affects the performance of the component. Commonly used spring materials include steel, carbon steel, stainless steel, aluminum, bronze, and nickel alloys. Different spring workloads and application environments require the selection of different materials. For example, when there are conditions of high temperature and corrosive environment, stainless steel or aluminum-grade alloys should be used. For components with large alternating load, mechanical performance and fatigue, special alloy spring materials need to be used.
Processing Technology
In the production of a spring, processing technology is also important in ensuring the performance and accuracy of the component. Generally, cold-formed technology is used, which has advantages of high efficiency and low cost. Even so, due to the poor heat conduction of spring pieces and various mechanical processes, it is easy to cause overheating, surface hardening and spring stiffness of the components. Therefore, cooling methods need to be implemented after mechanical processes to avoid high temperature deformation and cracking of components. In addition, taking into consideration of the working environment and conditions, the surface finish treatment of springs is also needed, such as shot peening and painting.
Conclusion
Inorder to achieve optimal performance and good quality in the production of springs, integrated design, material selection and processing technology are very important. In recent years, technical innovation and breakthroughs in the entire process of spring production have been achieved through creative designs, efficient processing technology and accurate selection of materials. This has greatly promoted the development of spring design and production, and will continue to do so in the future.
