Improved shot blasting machine for aluminum alloy castings

Abstract

The invention discloses an improved shot blasting machine for aluminum alloy castings. The improved shot blasting machine comprises a dust remover, a shot blasting machine body, a protecting door, a blasting head and springs; an electric hoist is arranged at the left end of the top of the shot blasting machine body; a guiding rail is arranged above the electric hoist; a supporting frame is arranged below the guiding rail; and an elevator is arranged at the right end of the guiding rail. A shot collecting groove is formed inside an original shot blasting machine, blasted steel shots can be better collected and can be conveyed out of a shot blasting chamber by the aid of a screw conveyor, and thus the smoothness of treatment of the castings inside the shot blasting chamber is kept; meanwhile, independent blade clamping grooves are formed in impellers inside a shot blasting device, are fixed by the aid of spring clamping plates and are convenient to dismount, so that blades can be changedseparately in case of failure, the blade changing speed is increased, and the utilization degree of the blades is increased; and the two impellers are arranged, so that the collision speed of the steel shots is increased, the casting treatment ability is improved, the service life of the shot blasting machine is longer, and the machining efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of processing aluminum alloy castings, and in particular relates to an improved shot blasting machine for aluminum alloy castings. Background technique [0002] Shot blasting machine is a casting equipment that uses high-speed projectiles thrown by a shot blaster to clean or strengthen the surface of castings. The shot blasting machine can simultaneously perform sand removal, core removal and cleaning on castings. In some areas, it is also called sand blasting machine or sandblasting. Machines, shot blasting machines can also be used to remove burrs, diaphragms and rust, which will affect the integrity and appearance of parts of the object. The shot blasting machine can also remove the pollutants on the surface of a part of the coating, and provide a surface profile to increase the adhesion of the coating to achieve the purpose of strengthening the workpiece. The shot blasting machine is different from the s...

Problems solved by technology

[0004] The purpose of the present invention is to provide an improved shot blasting machine for aluminum alloy castings, to solve the problem that the steel shots thrown by the shot blasting device cannot be timely Cleaning may cause blockage in the shot blasting chamber, which will affect the processing of castings. At the same time, the shot blaster is a vulnerable device. Damage to the internal blades of the shot blaster will cause damage to the castings from the steel shots thrown by the shot blaster, which will affect the casting processing. The replacement of blades requires a complete set of replacements. The replacement process is cumbersome and causes a certain waste of resources.
