Today, Wuxi IDEAL Machinery Manufacturing Co., Ltd. will introduce Wuxi shot blasting machine. 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 data object. Compared with other surface treatment skills, it is faster and more useful, and can be used for the casting process after partial preservation or stamping. The shot blasting machine can also be used to remove burrs, diaphragms and rust, which may affect the integrity, appearance, or definition of the object part. The shot blasting machine can also remove contaminants from the surface of a part of the coating, and provide an adhesive surface profile for adding the coating to achieve the intention of strengthening the workpiece.

Wuxi shot blasting machine is a cold working process, that is, the motor is driven by the sand blasting machine, and a small number of small circles called steel shot are used to continuously hit the surface of the parts. Each steel shot hits a metal part, like a small rod that hits the surface and pulls out small dents or depressions. In order to form a depression, the metal outer layer needs to be stretched. Under the outer layer, the compressed particles try to restore the outer surface to its original shape, and then produce a hemisphere with high tightening force.

Multiple depressions are stacked to form a uniform residual compressive stress layer, further enhancing the hardness and fatigue resistance of the workpiece. Significantly prolong the service life of the workpiece. The appearance of the newly cast castings is not uniform, leaving some burrs and clay sand. It needs intermittent polishing and rust prevention in the future. Some defective products also have pores on the surface, which poses a security risk to the application of the product. Therefore, it is necessary to check the appearance of the casting intermittently, and the shot blasting machine can well meet the above requirements.

What is the non-destructive flaw detection principle of Wuxi shot blasting machine? The casting is transported to the chamber of the sandblasting machine by hanging, crawling or rolling, and the workpiece rotates continuously and rolls in the chamber. A reasonably planned sand blasting machine is installed around the cleaning room of the shot blasting machine. The sand blasting machine can accelerate the metal shot blasting. Through severe metal shot impact, the casting with defective parts can be screened intermittently, and the air holes can be exposed early to prevent potential security risks in the later stage.

The above is the principle of using the shot blasting machine for discontinuous appearance nondestructive testing. When the workpiece of the shot blasting machine is entrusted, the workpiece to be disposed is transported to the cleaning room of the shot blasting machine through the escort system, and the steel shot (projectile) is accelerated to the initial speed of shot blasting, about 80 m/s, and the impeller rotates at high speed. On the surface of the workpiece, the surface of the workpiece is not connected, impacting in all directions to remove the rust, scale and dirt on the surface of the workpiece, so that the workpiece reaches the purpose of rust prevention and rust prevention.
