Description

A sandblasting device for foundry sand parts

technical field

The utility model relates to the technical field of sandblasting equipment, in particular to a sandblasting device for foundry sand parts.

Background technique

Products formed by sand casting require effective surface treatment to improve the surface quality of the blank and facilitate later processing. The commonly used surface treatment method is sandblasting. Sandblasting uses compressed air as the power to form a high-speed jet beam to spray materials (copper ore sand, quartz sand, emery, iron sand, sea sand) to the surface of the workpiece to be treated at a high speed, so that the appearance or shape of the workpiece surface changes. Due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface are improved, so the fatigue resistance of the workpiece is improved, and it and the coating are increased. The adhesion between them prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating.

At present, most of the sandblasting treatment of foundry sand parts is carried out by manual hand-held spray gun, which not only greatly increases the labor intensity of people, but also causes uneven sandblasting, thereby affecting the sandblasting effect. However, most of the sandblasting equipment currently used on foundry sand parts has problems such as low efficiency and insufficient sandblasting, and there are certain defects.

To this end, we propose a sand blasting device for foundry sand parts.
