Manufacturing springs: Spring steel strips have high elasticity and hardness, and can quickly return to their original shape after being subjected to force. Therefore, they are widely used in spring manufacturing in fields such as automobiles, mechanical equipment, furniture, and electronic products. For example, spring steel strips are commonly used in the manufacturing of springs for automotive suspension systems, braking systems, transmission systems, and other components.

 

Provide elastic recovery force: Springs made of spring steel strips can repeatedly expand and contract over a long period of time without permanent deformation or breakage, ensuring the normal operation of equipment or machinery. For example, the spring in the clutch can ensure that it quickly returns to its original shape after the force disappears, thereby ensuring the normal operation of the clutch.

 

Shock absorption and buffering: The shock absorption device made of spring steel strip can absorb and buffer the vibration and impact generated during the operation of the machine, improving the stability and service life of the equipment. For example, the coil springs used in the suspension system of vehicles can reduce bumps and improve ride comfort.

Clamping the workpiece: In some hardware fixtures, snap springs, and other tools, springs made of spring steel strips can achieve clamping of the workpiece, ensuring the stability of the part during processing. For example, the snap spring used in the machining process can provide sufficient clamping force, making installation and disassembly easier.
