Spring Shot Blasting Machine Unique Design

QINGDAO KNNJOO MACHINE INC. | Updated: Sep 29, 2017

Shot blasting machine can clean the metal surface of the various residues, Spring Shot Blasting Machine the castings can be sand, in addition to core and clean up. Shot blasting is the high-speed rotation of the impeller will be in the impeller center of the abrasive, Spring Shot Blasting Machine 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, Spring Shot Blasting Machine each impeller manufacturer has a unique design, Spring Shot Blasting Machine 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 castings 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 parts 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, Spring Shot Blasting Machine 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, Spring Shot Blasting Machine cold separation, from the skin and other essential means of technology. Non-ferrous metal castings, such as aluminum, copper alloy surface cleaning, in addition to scavenging oxide, found the casting surface defects, 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, Spring Shot Blasting Machine 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 dislocation density inside the metal is the main direction to improve the strength of the metal. Practice has proved that shot blasting is an effective process to increase the metal dislocation structure. This is of great significance to the fact that some metals can not be hardened by phase change hardening (such as martensitic quenching, etc.) or to achieve further hardening of the workpiece on the basis of hardening. Aviation, aerospace industry, automobiles, Spring Shot Blasting Machine 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.
