Pre-mixed abrasive water-jet shot-blasting equipment

Abstract

The invention provides pre-mixed abrasive water-jet shot-blasting equipment. The pre-mixed abrasive water-jet shot-blasting equipment comprises a water supplying box, a water outlet of the water supplying box communicates with a water inlet of a shot material tank through a water inlet pipe, and the water inlet pipe is sequentially connected with a filter, a water pump, a safe valve, a pressure adjusting valve and a one-way valve in series from the water supplying box to the shot material tank; a plurality of shot materials are stored in the shot material tank, and a material putting opening is formed in the top end of the shot material tank and matched with an end cover for sealing; an outlet of the shot material tank communicates with the inlet end of a shot material pipe used for conveying the shot materials, and a stop valve is arranged on the shot material pipe; the outlet end of the shot material pipe penetrates through a cantilever beam from top to bottom and communicates with anozzle, and the nozzle allows the shot materials to pass through; a displacement working table is arranged below the nozzle and erected on a water return box for recovery of water and the shot materials which are sprayed by the nozzle, and a clamp used for clamping a to-be-machined workpiece is arranged on the upper surface of the displacement working table; and the cantilever beam is located above the displacement working table and can horizontally move above the displacement working table through a moving device.

Description

technical field [0001] The invention relates to the field of surface processing, in particular to a pre-abrasive mixed water jet blasting equipment. Background technique [0002] Among the many surface modification technologies, the shot peening technology is the most effective in improving the fatigue resistance of metal and other components under alternating loads. , aerospace, construction, textile, metallurgy and many other fields, used for cutting, cleaning, derusting and crushing operations. [0003] The study found that the residual stress formed by high-pressure water jet shot peening on the surface of the workpiece can improve its fatigue resistance, but the residual compressive stress generated by the shot peening of the existing shot peening device and the uniformity of the shot peened surface roughness formed are not good. The surface roughness value of shot peening is too high, which affects the service life and contact accuracy of the workpiece. Contents of ...
