Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting, in particular to a sandblasting machine shell. Background Art

[0002] Sandblasting is a process for surface treatment of workpieces. Compressed air is used as the power to form a high-speed jet beam to spray the material at high speed onto the surface of the workpiece to be treated, so that the appearance or shape of the workpiece surface changes. Due to the impact and cutting action of the abrasive on the workpiece surface, the surface of the workpiece obtains a certain degree of cleanliness and different degrees of roughness, and the mechanical properties of the workpiece surface are improved, thereby improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating, and also facilitating the leveling and decoration of the coating.

[0003] Because of the high-speed moving spray material contacting the shell inside the sandblasting machine, the shell structure of the sandblasting machine is aged faster due to wear. In order to slow down the wear rate of the shell, the traditional sandblasting machine shell adopts an iron shell, which makes the shell thick and heavy, increases the weight of the sandblasting machine, and shortens the service life of the sandblasting machine shell.
