A shot blasting machine

Abstract

The invention relates to the field of metal surface treatment, in particular to a shot blasting machine, which includes a body structure, a cleaning structure, a rotating structure, a dehydration structure and a collection structure; on the one hand, the use of the cleaning structure facilitates the collection of ejected metal shots, and on the other hand On the one hand, the water flow is used to drive the metal shot to move, so that the metal shot can rub against each other, and the scale and dirt on the surface of the metal shot are washed away by the flow of water. At the same time, the flow of water increases the contact between the metal shot and the inner wall of the cleaning structure. , to facilitate the cleaning structure to brush off the scale and dirt on the surface of the metal shot; the use of the rotating structure enables the water inside the cleaning structure to move, so that the metal shot can fully contact with the water, and at the same time can drive the dehydration structure to rotate at a high speed, improving linkage and integrity ;The use of the dehydration structure can clean the water droplets carried by the metal shot, avoiding the operation of the metal shot with water, and at the same time, the metal shot can be quickly and orderly transported to the collection structure during dehydration.

Description

technical field [0001] The invention relates to the field of metal surface treatment, in particular to a shot blasting machine. Background technique [0002] The shot blasting machine uses the high-speed moving shot flow to impact the metal surface. On the one hand, it produces a plastic cyclic strain layer on the metal surface, which leads to favorable changes in the microstructure of the layer and introduces a residual compressive stress field into the surface layer. The microstructure and residual compressive stress field are two strengthening factors that improve the fatigue fracture and stress corrosion cracking resistance of metal parts, and as a result, the reliability and durability of the parts are improved. On the other hand, during the impact of the high-speed projectile flow on the metal surface, the scale and dirt on the metal surface will be taken away, and the metal surface will be cleaned. [0003] After the metal shot hits the surface of the workpiece, some...

Problems solved by technology

[0003] After the metal shot hits the surface of the workpiece, some scale or dirt on the workpiece will remain on the surface. If it is not cleaned in time, it will not only pollute and damage the metal shot, but also drop the scale and dirt to the surface during the recycling of the metal shot. Inside the machine, causing dust to accumulate inside the machine, affecting the normal operation and service life of the machine
