Spindle impeller head for drum-type shot blasting machine and shot blasting equipment

Abstract

The invention relates to a main shaft impeller head for a drum-type shot blasting machine and shot blasting equipment. Belongs to the technical field of impeller heads. The main shaft impeller head comprises a main shaft component, the main shaft component is arranged in a roller of a shot blasting machine, the main shaft component comprises a shot distributing pipe, a directional pipe and a shot blasting rotor which are coaxially arranged, one end of the shot distributing pipe is rotationally connected with the first end face of the roller of the shot blasting machine, and the other end of the shot distributing pipe is embedded in the first end of the directional pipe; the shot distributing pipe can rotate around the axis of the shot distributing pipe, the second end of the directional pipe is rotationally arranged on the second end face of the shot blasting machine roller, a plurality of first openings are formed in the outer wall face of the part, nested in the directional pipe, of the shot distributing pipe in the circumferential direction, a second opening is formed in the outer wall face of the directional pipe, and the shot blasting rotor is installed on the shot distributing pipe. And the shot blasting rotor comprises shot blasting blades, and when the shot distributing pipe rotates, shot blasting in the shot distributing pipe can sequentially pass through the first opening and the second opening and collides with the shot blasting blades to be thrown into a roller of the shot blasting machine.

Description

technical field [0001] The invention belongs to the technical field of shot blasting machines, and in particular relates to a main shaft shot blasting machine and shot blasting equipment for a drum type shot blasting machine. Background technique [0002] The statements herein merely provide background related to the present invention and do not necessarily constitute prior art. [0003] The drum shot blasting machine is usually used in the field of foundry machinery. Its working purpose is to carry out surface treatment such as cleaning residual sand, removing oxide layer, surface strengthening, etc. on the workpiece generated by casting or forging. The dead corners of the cavity are cleaned to make the attachments on the inner wall of the workpiece fall off, improve the smoothness and effectively strengthen the surface and increase the life of the parts. Since the workpiece is continuously turned over with the rolling of the drum during the shot blasting process, it is re...

Problems solved by technology

[0005] However, the inventors found that the current traditional drum type shot blasting machine needs to install multiple blasting devices at different positions on both sides of the drum to cover the processing range inside the drum through axial blasting, resulting in an excessive number of blasting devices And the processing angle is limited. At the same time, the structure of the traditional hopper for conveying shot blasting is simple, and it is impossible to control the shot blasting amount and shot blasting time.
