Stress shot peening apparatus of the coil spring

摘要

This invention may be then be rotated via a state compressing the coil spring is passed through a short room to allow the shot peening treatment to the coil spring surface, improve the internal stress of the coil spring, the generally cylindrical coil spring as as it relates to a coil spring of the stress shot peening apparatus to the shot peening treatment evenly on the entire surface of the side loading type coil spring also various shapes. Stress shot peening apparatus of the coil spring is then interposed between the spring clamping means for the facing each other by a compression by a spring clamping means facing the coil springs from one another rotation by by treatment shot peening so as to pass through the internal short room the internal stress compared to the shot peening treatment of the coil spring by a conventional shot peening apparatus has an effect that allows to produce significantly improved coil spring. In addition, the load of the shot by the coil spring to be pinned interposed between the spring clamping means facing each other transfer at the same time and rotates into the short room to allow for shot peening treatment, as well as a coil spring of a general cylindrical shape various shapes side-type coil spring also has the effect of evenly to a shot peening treatment over the entire surface. ; Coil springs, shot peening, stress, short ball, short-Room
