Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting equipment, in particular to a drawer-type double-station sandblasting device. Background Art

[0002] Sandblasting machine is a machine that uses compressed air as power to form a high-speed jet beam to spray the material at high speed onto the surface of the workpiece to be processed, so that the mechanical properties of the outer surface of the workpiece surface change. The working principle of sandblasting is to use compressed air as power to form a high-speed jet beam to spray the material (copper ore sand, quartz sand, corundum, iron sand, sea sand, etc.) at high speed onto the surface of the workpiece to be processed, so that the appearance or shape of the workpiece surface changes. Due to the impact and cutting action of the abrasive on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different roughness, so that 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. Sandblasting can also remove rust. Sandblasting rust removal is mainly a high-speed jet method formed by the principle of air compression as power. Sandblasting materials can be divided into several types, namely garnet sand, quartz sand, copper ore sand, iron sand, corundum, etc. This kind of sandblasting used on the surface of the workpiece can help it remove rust and effectively improve its surface. The pre-treatment stage of the sandblasting process refers to the treatment that should be performed on the surface of the workpiece before the workpiece is sprayed or coated with a protective layer. The quality of the pre-treatment of the sandblasting process affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating. If the pre-treatment work is not done well, rust will continue to spread under the coating, causing the coating to fall off in pieces.
