Today, Wuxi IDEAL Machinery will introduce the shot blasting machine. The shot blasting machine uses the high-speed rotating impeller to throw the shot into the continuously overturned workpiece in the drum to achieve the purpose of finishing. The shot blasting machine is applicable to the surface finishing, rust removal and shot blasting strengthening process of various medium and small castings, forgings and machined parts. It is applicable to different production scales, and can be used alone or in combination with multiple sets. It forms a production and finishing assembly line with continuous conveyor.

The shot blasting machine is a kind of processing skill that uses the shot blasting machine to drop the steel sand and steel shot at high speed and impact the surface of the material object. Compared with other surface treatment skills, it is faster and more effective, and can be used for the casting process after partial preservation or stamping.

It is an ideal finishing equipment for large, medium and small pieces, and is especially suitable for the surface finishing and strengthening of parts that are not afraid of collision. The casting is finished by shot blasting, and the price is convenient for the next machining process, which not only saves the processing time, but also protects the machine tool and tool from damage; After painting the non-machined surface, it will last for a long time and improve the service life and appearance quality of the product. So what factors affect the shot blasting strength of the shot blasting machine, mainly including the following points:

(1) Shot size

The greater the shot blasting, the greater the impact kinetic energy and the greater the shot blasting intensity, but the coverage of shot blasting decreases. Therefore, the smaller shot blasting should be selected as far as possible while ensuring the shot blasting strength. In addition, the size of shot blasting is also limited by the shape of the part. When there is a groove on the part, the diameter of shot blasting shall be less than half of the inner radius of the groove. Shot blasting size is usually selected between 6-50 meshes.

(2) Shot blasting strength

When the shot blasting hardness is higher than the part hardness, the change of its hardness value does not affect the shot blasting strength; When the shot blasting is softer than the part, if the shot blasting hardness value decreases, the shot blasting strength also decreases.

(3) Shot blasting speed

When the shot blasting speed is added, the shot blasting strength is also added, but when the speed is too high, the shot blasting damage amount is added.

(4) Injection viewpoint

When the shot blasting jet is perpendicular to the surface to be blasted, the shot blasting intensity is high, so the shot blasting treatment should generally be maintained in this state. If it is necessary to use small view point shot blasting due to the shape of parts, the size and speed of shot blasting shall be appropriately increased.

(5) Shot blasting breaking amount

The kinetic energy of shot blasting fragments is low, the more broken shot blasting, the lower shot blasting intensity, and the irregular shot blasting will scratch the surface of the parts. Therefore, the broken shot should be removed frequently to ensure that the shot blasting integrity rate is greater than 85%. Only some auxiliary equipment should be selected to control the shot blasting process more strictly.
