The principle of a spring machine is mainly based on Hooke's law, which states that the deformation of a spring is proportional to the force applied. When an external force is applied to a spring, the spring will deform and store elastic potential energy; When the external force disappears, the spring will return to its original state and release the stored energy, pushing the working parts to perform corresponding mechanical movements. The working process of a spring machine can be described as follows: the machine body fixes a section of spring steel wire at the tail of the spring machine, and through the drive of the driver, presses the steel wire into the forming mold at a moderate speed and force, causing the steel wire to deform. Finally, with the assistance of the machine body, the steel wire is wound into a predetermined shape, thereby manufacturing various types of springs. ‌

Spring machines have a wide range of applications, including automotive suspension systems, industrial machinery, clocks, toys, and other fields. Its design and application need to consider various factors, such as the material, size, stiffness of the spring, the design of the guiding device, and the characteristics of the working parts. Reasonable design can improve the efficiency and reliability of spring machines, extend their service life, and reduce maintenance costs.
