Problems solved by technology

[0003] In the existing sandblasting process, the castings are generally held manually through gloves, and then the surface of the castings is sandblasted and polished by manually using a spray gun. However, due to the poor stability of manual holding, it is very easy to The degree of sandblasting and polishing at each position is not uniform, resulting in poor overall polishing effect of the castings, and some sandblasting devices are used for sandblasting, but the existing sandblasting devices are not convenient for the removal of precision castings before and after sandblasting. put

Description

technical field [0001] The invention belongs to the technical field of sandblasting devices, in particular to a sandblasting device for precision castings. Background technique [0002] Sand blasting is the process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Compressed air is used as the power to form a high-speed jet beam to spray the spray material to the surface of the workpiece to be processed at high speed, so that the appearance or shape of the outer surface of the workpiece surface changes, which is often used in the polishing of castings. [0003] In the existing sandblasting process, the castings are generally held manually through gloves, and then the surface of the castings is sandblasted and polished by manually using a spray gun. However, due to the poor stability of manual holding, it is very easy to The degree of sandblasting and polishing at each position is not uniform, resulting in poor overall polishing e...
