Preparation mold mechanism of forward curved vane of shot blasting machine and preparation method

Abstract

The invention provides a preparation mold mechanism of a forward curved vane of a shot blasting machine and a preparation method. A vane substrate is configured as vane substrate solid particle powderwith the particle size ranging from 10 microns to 50 microns; the surface of the cavity wall of a preparation mold cavity is coated with a fluorocarbon resin release agent; a supersonic speed cold spray Laval nozzle extends into an injection hole of a preparation mold, solid particles are sprayed into the mold cavity, and the cavity is filled with the particles to form a vane rough blank; and mold opening is carried out, and the vane rough blank is subjected to water toughening treatment. By means of the preparation mold mechanism and the preparation method, the vane molding preparation method is improved, high efficiency is achieved, the hardness and compactness of the shot blasting machine are improved, the wear resistance of the vane is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of shot blasting machines, in particular to a preparation mold mechanism and a preparation method of a front curved blade of a shot blasting machine. Background technique [0002] During the working process of the shot blaster, the projectile is driven by the rotating blade to provide it with a certain initial velocity, and then the projectile is thrown out and bombarded on the surface of the workpiece for surface treatment. Therefore, the blade of the shot blaster will be impacted by the projectile, causing friction and wear, especially the curved surface design of the forward curved blade, which uses centrifugal force to increase the initial velocity of the projectile, but it is precisely because of this curved surface design that the blade is more prone to wear , to shorten its service life. [0003] Traditional blasting machine blades are usually cast. Although the cost is low and the efficiency is hi...

Therefore, the blade of the shot blaster will be impacted by the projectile, causing friction and wear, especially the curved surface design of the forward curved blade, which uses centrifugal force to increase the initial velocity of the projectile, but it is precisely because of this curved surface design that the blade is more prone to wear , shorten its service life

[0003] The traditional blasting machine blades are usually cast. Although the cost is low and the efficiency is high, casting defects such as shrinkage porosity and shrinkage cavity are unavoidable.
