Description

Shot blasting machine for casting

Technical Field

The utility model relates to a casting equipment technical field especially relates to a shot-blasting machine is used in casting.

Background

The shot blasting machine is mechanical equipment for cleaning or strengthening the surface of a workpiece by using high-speed shots thrown by the shot blasting machine. The shot blasting machine can simultaneously perform sand falling, core removal and cleaning on the casting. Can also be used for surface treatment of forged parts, aluminum-magnesium alloy parts, metal plate welded parts and the like. In some areas, the mouth is also called a sand blasting machine and a sand blasting machine. The shot blasting machine is a processing technology for throwing steel grit steel shots at high speed to impact the surfaces of material objects through a shot blasting machine. It is faster, more efficient than other surface treatment techniques, and can be used for part retention or casting processes after stamping. The first shot-blasting machine was made in the world by united states corporation in the 30's of the 20 th century. The production of the shot blasting strengthening equipment in China begins in the 50 s of the 20 th century and mainly simulates the former Soviet Union technology. Shot blasting machines may also be used to remove burrs, membranes, and rust that may affect the integrity, appearance, or definition of portions of an object. The shot blasting machine can also remove pollutants on the surface of a part of coating and provide a surface profile for increasing the adhesive force of the coating, so as to achieve the purpose of strengthening the workpiece. The shot blasting equipment is firstly applied to the removal of the surface sand-sticking and the oxide skin of cast steel and iron castings in the casting industry. Almost all steel castings, gray castings, malleable iron castings, ductile iron castings, etc. are shot-blasted. This is not only for removing scale and sand sticking on the surface of the casting, but also an indispensable preparation step before the quality inspection of the casting.

The hook type shot blasting machine is widely applied to surface cleaning or strengthening treatment of medium and small cast and forged pieces in the industries of casting, building, chemical engineering, motors, machine tools and the like, workpieces are loaded by two hooks and alternately enter a shot blasting cleaning chamber, and shots with the thickness of 0.2-0.8 mm are thrown to the surfaces of the workpieces by using a shot blasting machine, so that the surfaces of the workpieces reach certain roughness, the workpieces are attractive, or the compressive stress of the workpieces is changed, and the service life is prolonged. However, in the using process, the shot can splash out from the strip-shaped notch at the top of the shot blasting chamber, which is not only easy to hurt people, but also causes damage to certain parts outside and waste of the shot. The common solution is to directly mount a rubber plate at the strip-shaped notch, and the sealing effect is not good.
