Method for casting antiwear shot blasting machine blade

Abstract

The invention provides a method for casting an antiwear shot blasting machine blade. The method comprises the following steps that S1, green sand is utilized for carrying out modeling on a casting of the antiwear shot blasting machine blade, and dry sand is utilized for carrying out core making on the casting of the antiwear shot blasting machine blade; S2, casting lower surface parting of the antiwear shot blasting machine blade is selected, and a bottom gating system is selected; S3, the dimensional tolerance, the casting weight tolerance, the shrinking percentage, the pattern draft and the air outlet hole dimension during casting are determined; S4, an alloy is subjected to smelting and casting; and S5, after the casting is put in the temperature being 900 DEG C for heat preservation for 0.5 h after casting is carried out, the casting is taken out of a furnace to be cooled, and the casting is cooled after being subjected to heat preservation tempering for 0.5 h at the temperature being 220 DEG C. The method for casting the antiwear shot blasting machine blade has the following beneficial effects that by means of the method, a structure growing perpendicularly to the direction of the wear face of the blade can be obtained, on the premise of no greatly improving production cost, the wear resistance of the structure is greatly improved, and application is wider.

Description

technical field [0001] The invention relates specifically to a casting method of a wear-resistant shot blasting machine blade. Background technique [0002] Shot blasting cleaning technology has the advantages of high efficiency, good effect, easy control of air pollution and less investment. It is more and more widely used in machinery, automobiles, aviation and other industries. It is not only used for rust removal and cleaning of metal surfaces , It is also used for the strengthening of workpieces such as automobile decoration, gears, connecting rods, leaf springs, etc. It is also used for the pitting of workpieces before forming and coating chemical treatment. The shot blaster uses the centrifugal force to throw the abrasive at high speed, impacting the surface of the workpiece to cause the surface scale, rust layer, sticky sand or impurities to peel off, or to deform the surface and generate compressive stress.

Problems solved by technology

[0003] However, in the actual engineering application of the shot blasting machine, many problems have appeared. For example, the shot blasting wheel, orientation sleeve, blade and liner in the shot blasting machine are all parts that are easy to wear, especially the blades of the shot blasting machine are easy to wear For this reason, the service life of the shot blasting machine is severely limited. The present invention mainly studies how to solve this problem and how to solve the easy-wearing situation of the shot blasting machine blades at a low price.
