Spring Shot Blasting Machine A Larger Range

QINGDAO KNNJOO MACHINE INC. | Updated: Jun 21, 2017

Shot blasting machine, not to compressed air as the driving force, but to electric machinery shot blasting machine as a driving force, Spring Shot Blasting Machine the use of shot blasting machine throwing high-speed projectile to clean or strengthen the surface of metal parts equipment. Shot blasting machine can clean up the metal surface of the various residues, the castings can be sand, Spring Shot Blasting Machine in addition to core and clean up. Shot blasting is a high-speed rotation of the impeller, will be in the impeller center of the abrasive, through the regulator block (Regulator) and impeller pusher (Impeller) pre-acceleration, into the blade area and then throw high-speed abrasive, the speed can be more than 100m / s, As the shot blasting coverage is large, so do not use air pressure, energy efficiency is much higher than sandblasting. Impeller is the heart of the shot blasting machine, driven directly or indirectly by the electric motor, each impeller manufacturer has a unique design, mainly divided into single platter and double disc impeller. Shot blasting machine, the use of shot blasting machine throwing high-speed projectile cleaning or strengthening the casting surface casting equipment. Shot blasting machine at the same time on the casting of sand, in addition to core and clean up. Mainly the use of high-speed rotation of the impeller to throw out the pill sand, high-speed impact parts surface, to meet the requirements of surface treatment.

Shot blasting equipment is first used in the casting industry cast steel, cast iron pieces of the surface of sand and the removal of oxide. Almost all of the cast steel, Spring Shot Blasting Machine gray castings, Magang, ductile iron and so on to be shot blasting. This is not only to remove the surface of the castings oxide and sticky sand, but also the casting quality inspection before the indispensable preparation process, such as large gas turbine chassis in the nondestructive testing must be carried out before the strict shot peening to ensure the results of the test reliability. In the general casting production, throwing shot peening is found in the casting surface defects such as subcutaneous stomata, slag and sticky sand, cold separation, Spring Shot Blasting Machine from the skin and other essential means of technology. Non-ferrous metal castings, such as aluminum alloy, copper alloy surface cleaning, in addition to the removal of oxide, found the casting surface defects, Spring Shot Blasting Machine the more important purpose is to throw shot peening to remove the burrs of die cast and get a decorative surface quality , To obtain a comprehensive effect.

Metallurgical Iron and steel production, Spring Shot Blasting Machine throwing shot pills is to ensure that a large number of steel production in order to obtain high productivity and the use of a chemical-chemical combination of phosphorus removal of a process. Silicon steel sheet, stainless steel sheet and other alloy steel plate, with the production process, in the cold rolling process must be carried out annealing a shot blasting treatment to ensure that the cold-rolled steel plate surface roughness and thickness accuracy.

According to the theory of modern metal strength, increasing the internal dislocation density of the metal is to improve the metal

Strength of the main direction. Practice has proved that shot blasting is to increase the metal dislocation structure of the effective process. This is of great significance to the fact that some metals can not be hardened by phase change hardening (eg, martensitic quenching, etc.) or to achieve further hardening of the workpiece. Aviation, aerospace industry, automobiles, tractors and other parts of the requirements of light, but the reliability requirements are getting higher and higher, the important process is to use throwing shot peening process to improve the strength and fatigue strength.
