【 摘 要 】

Springs operating at high load speeds with coils collision or under static low-cycle contact load between coils, exceeding the strength of the compression of the spring, are used in engineering, auto and defense industries. Unfavourable conditions in the operation lead to considerable residual deformations, development of latent defects of the metal of springs and their breakage. This decreases the reliability and safety of machines and pieces of machinery. The recommended method to harden and control the quality of such springs is plastic surface treatment - contact predeformation. To harden conical springs having the forming surface of a complex shape, the modernization of the device for contact spring hardening has been offered. The device can be used in mass industry. The advantage of the modernized device as compared to all known is that it can increase the resource of conical compression springs up to 40%.
