| 总结: | In the process of operation, coil springs undergo considerable temperature, static and cyclic (contact among others) loads and other unfavourable effects. Latent defects in the metal, inadmissible residual deformations, and excessive compression arise in springs. To save the resource and increase the quality of springs repair production enterprises, defense, engineering and auto industries require improvement of the existing methods of repairing of the springs having lost their resistance. The recommended methods of spring repairing are the methods of thermo mechanic processing in combination with plastic surface treatment, namely contact predeformation and peen hardening. A new method of spring repairing from preliminary hardened wire is offered. The advantage of this method, in reference to the known ones, is in the extension of technological capacity and improving the quality of repaired springs |
