Automatic Consecutive Turntable Sandblasting Machine
The machine is equipped with 12 spray guns, the nozzle aperture φ8mm, material: boron carbide，and equipped with a blow dust gun. Spray gun pressure, angle, distance, moving speed can be adjusted according to surface requirements, to maximize the work piece accuracy, to achieve the desired surface effect. The other part of the work piece outside the host to take place with a manual blow gun, it is possible that the work piece from the blowing area to take place when a little dust fall, you can manually blow gun to achieve the final clean-up. In the sandblasting processing, there are three stations at the same time accept blasting processing, loading and unloading of the three parts, a worker can operate the loading and unloading.
How it works: The machine uses suction-type sandblasting, that is, the use of compressed air in the spray gun to produce high-speed negative pressure to produce the role of ejectors, cyclone storage tank abrasive through the sand tube into the gun, and then with the compressed air flow from the Nozzle high-speed shot to the work piece surface, to achieve the purpose of sandblasting processing. In the working state, the compressed air and sand mixed edge of the edge of the jet, so that full use of compressed air, air flow and sand flow to facilitate the adjustment, to get the ideal mix, energy and sand consumption is low, clean and efficient, Widely used in small household appliances industry, applicable to disc type, cylindrical type, square-shaped work piece inside and outside the surface blasting.
Main Functions：
First, spray to the surface of the work piece in the abrasive surface of the impact grinding, the surface of the work piece to remove impurities and oxide, so that surface area increases, improve the coating adhesion and improve coating quality. Second, the structure can be dispersed within the residual stress, to harden the work piece surface, increasing the surface of the plastic part of the deformation and fracture resistance, and the surface of the work piece to produce compressive stress and improve its fatigue strength. Third, the work piece surface defects and mechanical damage reduction, reducing stress concentration.
Sand blasting material: 24#~280# abrasive.
Processing range: Maximum diameter 350mm work piece, the maximum height of 250mm.
Processing efficiency: The actual production depends on the shape of the work piece and sand blasting effects to determine. (According to customer requirements, including the placement of products, include time, large size of about 550 per hour, small size of about 700 per hour.)
Work process: Open the automatic control system → large turntable and small turntable motor start → manually the work piece on the small turntable on the fixture → work piece into the blasting area → spray gun automatically start work on the work piece surface blasting → rotary turret → spray gun continuous sandblasting → the next station to continue to shift to the sandblasting area → sandblasting gun blowing the work piece to complete the blasting → to be turned over the work piece blasting processing, the work piece by the workers to flip, the next A cycle of operation, processing is completed, the workers loading and unloading parts.
Put on work piece → into the processing position → blasting → blowing →take off work piece→ cleaning
1) Turn on the power; turn on the compressed air source;
2) Host lighting, according to the size of the work piece to be processed, adjust the height and angle of the gun and fastening;
