In industrial processing, sandblasting is a common surface treatment process, which mainly plays the following roles:
Cleaning the surface: sandblasting can remove dirt, paint, oxide layer, rust, and attachments from the surface of the workpiece. By spraying sand particles at high speed, these substances can be washed away from the surface of the workpiece, making the surface clean.
Increase roughness: sandblasting can form a certain roughness on the surface of the workpiece, increasing the surface roughness. This helps to improve the adhesion between the workpiece and the coating, adhesive, etc., and enhances the bonding performance of the coating.
Improving surface quality: sandblasting can improve the quality of the workpiece surface, removing surface irregularities, burrs, bumps, and defects. By sandblasting, the surface of the workpiece can present a more uniform, flat, and smooth state.
Increase surface accuracy: sandblasting can form fine pits and textures on the surface of the workpiece, improving surface accuracy. This helps to improve the dimensional and shape accuracy of the workpiece, meeting engineering requirements.
Increase surface adhesion: sandblasting can form a small concave convex structure on the surface of the workpiece, increasing the contact area of the surface. This helps to improve the contact area and adhesion between the workpiece and the coating, adhesive, etc., and enhances the adhesion performance of the coating.
Repair and repair: Sandblasting can repair and repair defects and damages on the surface of workpieces, such as scratches, wear, and oxidation. By using appropriate sandblasting techniques and sand particle selection, the surface of the workpiece can be restored to a flat, smooth, and flawless state.
Sandblasting plays an important role in industrial processing, as it can clean surfaces, increase roughness, improve surface quality and accuracy, increase surface adhesion, and repair and repair surface defects. This helps to improve the quality and value of the product, meeting the requirements of different industries for the surface of the workpiece.
Shot Blasting Machine
Shot blasting machine is a common surface treatment equipment mainly used for cleaning, removing surface dirt and oxide layers, and enhancing surface roughness. The following is the general working principle and workflow of the shot blasting machine:
Loading workpieces: Firstly, place the workpieces to be processed in the studio of the shot blasting machine. A studio is usually a sealed container that can accommodate workpieces and shot blasting media.
Injecting shot blasting medium: Inject an appropriate amount of shot blasting medium, such as steel shot, aluminum shot, glass bead, etc., into the studio. The selection of shot blasting medium is based on the material and processing requirements of the workpiece.
Start the shot blasting machine: Start the motor and conveying system of the shot blasting machine. The motor will drive the shot blasting wheel inside the shot blasting machine to rotate at high speed, generating centrifugal force.
Shot blasting process: After the shot blasting machine is started, the shot blasting wheel projects the shot blasting medium onto the surface of the workpiece. Under the action of centrifugal force, the shot blasting medium impacts the surface of the workpiece at high speed to remove surface dirt and oxide layer, while improving surface roughness.
Recycling and recycling of shot blasting media: During the shot blasting process, the shot blasting media will collide and friction with the surface of the workpiece, and some of the shot blasting media will be ejected and scattered. The shot blasting machine is equipped with a recycling system for collecting and recycling shot blasting media to improve resource utilization efficiency.
Filtering and cleaning shot blasting media: The shot blasting machine is equipped with a filtering system for filtering and cleaning the recovered shot blasting media. By filtering the system, dirt, impurities, and worn shot blasting media can be removed, maintaining the cleanliness and performance of the media.
Stop the shot blasting machine: After the workpiece processing is completed, stop the operation of the shot blasting machine. Remove the processed workpiece for subsequent processing and inspection.
The above is the general working principle and workflow of the shot blasting machine. The specific working mode and parameter settings of the shot blasting machine may vary depending on different equipment types and processing requirements. When using a shot blasting machine for work, please follow the relevant operating procedures and safety guidelines.
