The automatic sandblasting machine is a kind of sand processing equipment. That can use abrasives to spray on the surface of the workpiece with the help of compressed air power. The sand blaster machine mainly sprays the spray material on the surface of the workpiece to process it at a high speed to change the appearance or shape of the workpiece. Mobile sandblasting equipment is mainly divided into two categories: dry sandblasting machines and wet sandblasting machines.
Working Principle of the Automatic Sandblasting Machine:
The automatic sandblaster uses compressed air to make sand with a diameter of 1~4mm form a high-speed flow of sand and spray it on the surface of the workpiece to remove burrs and rust spots on the surface of the workpiece. Mobile sandblasting equipment generally consists of a sand storage box, workbench, work cabinet, and other parts. Sandblasting is generally carried out in a closed box to avoid the impact of dust on the environment. According to the different sand conveying methods, the mini sandblasting machine mainly includes three types: suction type, self-flow type, and pressure type.
The work piece is conveyed by a triangular belt without sand accumulation. And the belt speed matches with the sandblasting process to realize frequency conversion speed regulation.
The angle of the spray gun can be adjusted freely. The gun frame can realize automatic frequency conversion swing and fixed-point spraying, which has strong flexibility.
The automatic sandblasting machine equipment adopts an advanced separation system configuration, which has a good dust separation effect and good sandblasting effect;
Using a PLC electrical control system, high degree of automation, good stability, and low failure rate;
The nozzle is made of special high wear-resistant materials, with long service life;
Independent bag-type dust removal system, good dust extraction, and ventilation effect;
Sand blasting machine can be applied to treat metal corrosion layer, residual salt and oxide layer on the surface of heat-treated parts, residual dirt and tiny burrs on the surface of the workpiece, and the surface of old parts to remove the surface adhesion layer and reveal the nature of the matrix.
Pretreatment before coating the surface of the workpiece
Sand blaster machine can be used as a pre-treatment process for various electroplating processes, brush plating processes, spraying processes, and bonding processes to obtain an active surface and improve the adhesion between the plating, coating, and bonding parts.
Change the physical and mechanical properties of the workpiece
Automatic sandblasting equipment can change the surface stress state of the workpiece. Improve the lubrication conditions of the mating parts, reduce the noise during the movement of the mating parts, harden the surface of the workpiece, and improve the wear resistance and fatigue strength of the parts.
Finishing processing of the surface of the workpiece
Portable sandblasting equipment can change the surface roughness Ra value of the workpiece, and produce a matt or diffusely reflective workpiece surface to achieve the purpose of finishing.
Ensure that the basic metal parts are not damaged, and the dimensional accuracy will not change;
The surface of the part is not contaminated, and the abrasive will not chemically react with the material of the part;
The small automatic sandblaster can easily handle grooves, concave, and other difficult-to-contact parts. And a variety of abrasives can be selected for us.
Reduce the processing cost greatly, improving the work efficiency, and meeting various surface finishing requirements.
The sandblaster machine does not damage the surface of the product, improves the appearance quality of the product, and increases the service life of the product.
