A kind of stress shot blasting machine

Abstract

The invention discloses a stress shot-blasting machine which comprises a shot-blasting chamber, a rotating stage component, a shot bin, at least one blast head and a shot circulating transmission mechanism, wherein the shot bin is arranged below the rotating stage, and at least one blast head is arranged on the shot-blasting chamber; and the stress shot-blasting machine is characterized by comprising at least one set of compressed rotating mechanism, a shot material circulating control transmission mechanism, a rotating stage driving mechanism, a blast head and an electric control device for the work of at least one set of compressed rotating mechanism. Each compressed rotating mechanism comprises a rotary component support, at least one set of spring pressure seat rotation component, and a lifting drive mechanism, the at least one set of spring pressure seat rotation component is fixed on the rotary component support, each set of the spring pressure seat rotation component comprises a spring pressure seat and a spring pressure seat rotary driving mechanism for driving the spring pressure seat to rotate; and the lifting drive mechanism is used for driving the spring pressure seat rotation component to move up and down. After the adoption of the utility model, when shot-blasting treatment is performed on a spring, the spring is compressed and rotated, so that the rate of coverage of the shot-blasting treatment is improved, and the fatigue life of the spring is prolonged.

Description

technical field [0001] The invention relates to a stress shot blasting machine. Background technique [0002] Shot blasting is to throw metal shot to the surface of the workpiece, so as to play the role of surface cleaning and surface strengthening. The shot blasting process has been widely used in spring manufacturing, but the existing shot blasting equipment for springs does not have a mechanism for compressing and rotating the spring during shot blasting. When the spring is shot blasted in an uncompressed state, it is bound to be difficult to fully eliminate the stress concentration on the surface of the spring, thereby affecting the fatigue life of the manufactured spring. In addition, if the spring does not rotate all the time during shot blasting, the coverage of shot blasting will be affected, and it is difficult for the spring to obtain a uniform surface treatment. Contents of the invention [0003] The technical problem to be solved by the present invention is t...

The shot blasting process has been widely used in spring manufacturing, but the existing shot blasting equipment for springs does not have a mechanism for compressing and rotating the spring during shot blasting.

When the spring is shot blasted in the uncompressed state, it is bound to be difficult to fully eliminate the stress concentration on the surface of the spring, thus affecting the fatigue life of the manufactured spring

In addition, if the spring does not rotate all the time during shot blasting, the coverage of shot blasting will be affected, and it is difficult for the spring to obtain a uniform surface treatment.
