Working principle of shot blasting machine
Shot blasting machine is a kind of casting equipment which uses high speed shot blasting to clean or strengthen the casting surface. The shot peening function can also be used for sand blasting, core removal and cleaning of castings at the same time. The shot blasting machine adopts high-speed impact treatment technology of steel sand and shot blasting technology to carry out shot blasting treatment on the object surface. Compared with other surface treatment technology, it is faster and more effective, and can be used in partial retention or stamping casting process. Shot blasting machines can also be used to remove burrs, diaphragms, and rust, which may affect the integrity, appearance, or definition of the object.
The shot blasting machine can also remove surface contaminants from a part of the surface of the coating, and provide a surface profile to increase the adhesion of the coating to achieve the purpose of strengthening the workpiece. The difference between shot blasting machine and shot blasting machine is that it is used to reduce the fatigue life of parts, increase different surface stress, increase the strength of components, or prevent wear.
Working principle: whether the shot blasting machine is powered by compressed air, but the mechanical and electrical shot blasting machine can speed up the metal surface by throwing high-speed shot or shot blasting cleaning equipment. The metal surface cleaned by the shot blasting machine can be various residues, and can be sand cut off the casting for core removal, cleaning, etc. When the impeller rotates at a high speed through sandblasting, the abrasive center of the impeller flows through the pre accelerated blade area of the transfer block (pressurizer) and the impeller pusher (impeller) to a high speed, and then it is abraded, exceeding the speed of 100M / s, which has a large coverage. Due to blasting, no pressure is required, and the energy efficiency is much higher than sandblasting.
Impeller is the heart of shot blasting machine, directly or indirectly driven by electric motor. Each manufacturer has its own unique impeller design, which is divided into single disc and disc impeller. Blast or strengthen the surface of casting equipment with high-speed projectiles. Photo function while casting drop sand, in addition to core and cleaning. It uses a rapidly rotating impeller to throw out shot sand and impact the surface part at high speed to meet the requirements of surface treatment.
