Shot blasting machine and shot blasting process

Abstract

The invention relates to a shot blasting machine which comprises a rack, a shot blasting box is arranged on the rack, the bottom wall of the shot blasting box is inclined, a chip removal opening is formed in the lower end of the bottom wall of the shot blasting box, an inclined filter screen is vertically installed on the portion, below the chip removal opening, of the rack in a sliding mode, and the rack is provided with a driving mechanism used for driving the filter screen to move. The shot blasting machine has the effects that as the filter screen is vertically and slidably installed on the rack and the rack is provided with the driving mechanism to drive the filter screen to vertically slide in a reciprocating manner, when the filter screen separates a mixture of scrap iron and shots, the scrap iron and broken shots in the mixture are not liable to be clamped on meshes of the filter screen when penetrating through the meshes of the filter screen, the separation effect of the filter screen on the mixture is improved, then the purity of shots falling into a shot box is improved, the number of the scrap iron and the broken shots carried by the shots fed into a shot blasting device from the shot box is small, and then the shot blasting effect of the shot blasting device on a workpiece is improved.

Description

technical field [0001] The present application relates to the field of parts post-processing equipment, in particular to a shot blasting machine and a shot blasting process. Background technique [0002] Shot blasting machine is a device used to sprinkle iron shot on the surface of parts to derust and strengthen the surface of parts. [0003] A common shot blasting machine includes a frame. The frame is equipped with a rectangular shot blasting box and a shot blasting device for shot blasting. The shot blasting device is fixed on the side wall of the shot blasting box, and the workpiece is fed into the shot blasting box. Then start the shot blaster to strengthen the surface of the workpiece by shot blasting. The projectiles that lose kinetic energy when they hit the workpiece and the iron filings that fall off from the workpiece due to the impact of the projectiles mix with each other and fall on the bottom wall of the shot blasting box. The bottom wall of the shot blasting ...
