Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a special steel wire for high-performance coil springs. Background Art

[0002] The coil spring can continuously provide a large restoring force in a small space. After a mechanical part completes a stroke, it can return the part to its original position to prepare for the next stroke. It is currently widely used in garden tool starters, vacuum cleaners and other winding parts. The design of the coil spring must determine the minimum driving torque and the maximum torque that can be used; the torque and speed of the final actuator driven; and the total time required for driving. The factors are selected from the table in the relevant design manual, and the size of the barrel and the size and modulus of the gear are determined. After testing, they are corrected and finally the parameters of each part are determined.

[0003] Coil springs are widely welcomed by people because of their exquisite structure, convenient use and convenience. Although coil springs have the above characteristics, they cannot meet the demand of modern life for tensile structures due to their low deformation efficiency and low strength. Therefore, a special steel wire for high-performance coil springs is proposed to solve the above problems. Utility Model Content
