Shot blasting technology is one of the advanced processes internationally used for surface cleaning, strengthening, polishing, and deburring various mechanical components. The equipment primarily consists of a shot blaster, abrasion-resistant rubber belt, auger, hoist, separator, feeding conveyor, dust collector, and a combination of cleaning machinery.
Currently widely adopted across various industries, this machine boasts high-tech functionality, capable of designing PC control and electrical automatic control systems. It features automatic monitoring, protection, and variable frequency speed regulation. It achieves the purpose of multi-functional use. Its main principle abandons the use of compressed air as a power source, opting for the projection of abrasive particles using a blast gun and centrifugal force, which高速projects onto the workpiece surface, particularly the hard-to-reach internal corners, for effective cleaning. This process achieves the desired brightness, cleanliness, roughness, and surface strengthening, significantly enhancing the lifespan and aesthetic appeal of the parts.
The three main applications of the shot blasting cleaner are as follows:
The shot blasting machine generates compressive stress on the surface of parts, enhancing their fatigue strength and resistance to tensile stress corrosion.
The shot blasting machine can correct distorted thin-walled parts.
The abrasive blasting cleaning process replaces conventional cold and hot forming techniques for shaping large thin-walled aluminum components. This not only prevents residual tensile stress on the component surface but also achieves favorable compressive stress. It should be noted that the usage temperature of components processed by the abrasive blasting cleaner should not be too high; otherwise, the compressive stress will automatically disappear at high temperatures, thereby losing the expected effect. The usage temperature is determined by the material of the component, with general steel components around 260-290°C, and aluminum components only 170°C.
Art of Sandblasting Cleaner Operation
During the shot blasting cleaning process, it is advisable to place more workpieces within the blasting zone. This not only enhances cleaning efficiency but also reduces the wear on the protective plates, thereby extending their service life.
2. In the event that workpieces cannot be increased, the directional sleeve should be adjusted to ensure the maximum amount of steel shot is projected onto the workpiece. This also extends the life of the protective plate and reduces wear.
3. ①Adjust the gate valves at all locations of the dust removal system's branch pipes to ensure a reasonable distribution of wind, which can enhance the dust removal effect. ②Ensure regular ash cleaning for the dust collector.
