What is shot blasting equipment
2020-12-10
What is shot blasting? Shot blasting and rust removal technology is one of the most advanced processes in the world for surface cleaning, strengthening, polishing and deburring of various machine parts.
Shot blasting machine is mainly composed of shot blasting device, wear-resistant rubber ring belt, screw auger, lifting, separator, feeding conveyor, dust removal machine, and electrical appliances. It has been widely adopted by many industries. This machine has high functional and technical content, and can be designed with PC control and electrical automatic control, with automatic monitoring, automatic protection and stepless frequency conversion speed control devices.
Can achieve the purpose of one machine with multiple functions. The main principle is to abandon the compressed air as the power method, and use the shot blasting device and centrifugal force to project the surface of the workpiece at high speed, especially to clean the dead corner of the inner cavity of the workpiece, so as to achieve the required brightness, cleanliness, and roughness. The purpose of strengthening the surface of the workpiece and improving the service life and aesthetics of the parts greatly.

How to choose a shot blasting machine suitable for your workpiece?
Time of issue : 2020-12-10 17:20:42
First of all, you can choose according to the size of your product. If the product size is relatively small, you can choose a crawler shot blasting machine. Crawler-type shot blasting machine is mainly suitable for surface treatment, rust removal and shot blasting of various hardware tools, medium and small castings, forgings. The crawler-type shot blasting machine is suitable for different production scales. It can be used as a single machine or in combination with multiple machines to form a production cleaning line with continuous conveyors.
If your product is a large part or the like, you can choose a hook type shot blasting machine, if it is a channel steel, steel pipe and other relatively large workpieces, you can choose a through-type shot blasting machine. The hook type shot blasting machine has the advantages of large shot blasting capacity, high shot blasting cleaning efficiency, large indoor working space, compact structure, and adopts a pit-free form. There is no special requirement for the shape and structure of the cleaning workpiece. It can be used for multiple purposes. Series products are widely used in shot blasting machinery manufacturing and foundry industry.

The principle of shot blasting machine non-destructive inspection and prolonging the life of the workpiece
Time of issue : 2020-12-10 17:19:54
Shot blasting machine cleaning and strengthening is a cold treatment process, that is, the motor drives the shot blasting device to operate and continuously hits the surface of the part with countless small circular media called steel shots. Each steel shot hits the metal part, like a tiny rod beating the surface, making small indentations or depressions. In order to form depressions, the metal surface layer must be stretched. Under the surface layer, the compressed crystal grains try to restore the surface to its original shape, thereby generating a hemisphere under the action of high compression force. Numerous depressions overlap to form a uniform residual compressive stress layer, which further improves the indicated hardness and fatigue resistance of the workpiece. Can significantly extend the service life of the workpiece.
The surface of the newly-fired castings is not tidy, and some burrs and clay sand will remain, which requires later sanding and rust prevention treatments. There are pores on the surface of some defective products, which leave a safety hazard to the use of the product. Therefore, the surface of the casting needs to be treated with surface flaw detection. The shot blasting machine can well meet the above requirements.
Then, what principle does the shot blasting machine use for surface non-destructive testing? The casting is transported to the shot blasting machine room by hanging, crawler or roller, and the workpiece is continuously rotated and rolled in the room. The shot blasting machine is equipped with a well-arranged shot blasting device around the cleaning room, which can accelerate the ejection of metal shots. Through intensive metal projectile strikes, sand can be effectively cleaned and polished, and defective castings can be screened at the same time. The pores will be exposed in advance to avoid potential safety hazards later. The above is the principle of surface non-destructive inspection using shot blasting machine.
Many steel materials and parts are constantly in contact with moist air during the placement process, resulting in a series of chemical reactions, and a layer of oxide scale and rust spots are formed on the surface over time, resulting in the aesthetics and deep processing of their use. Negative impact, at this time, the use of shot blasting machine for shot blasting and rust removal is particularly important.
When the shot blasting machine is working, the conveying system transports the workpiece to be processed to the cleaning room of the shot blasting machine, and uses the high-speed rotating impeller of the shot blasting machine to accelerate the steel shot (projectile) to an initial speed of about 80m/s. Polishing to the surface of the workpiece, the surface of the workpiece is continuously impacted and scraped in all directions to remove the rust, oxide scale and dirt on the surface of the workpiece, so that the workpiece can achieve the purpose of rust removal and rust prevention.
