Hook type shot blasting machine is a kind of shot blasting machine. The hook type shot blasting machine uses a high-speed rotating impeller to throw projectiles onto the continuously rotating workpiece in the drum, thereby cleaning the workpiece. It is suitable for sand removal, rust removal, scale removal and surface strengthening of castings and forgings under 15 kg in various industries. Because the hook shot blasting machine has a unique dust collection device, the installation location is not restricted by the ventilation ducts of the workshop, and the sanitary conditions are good. The hook type shot blasting machine mainly adopts shot blasting technology. It is a cleaning machine composed of shot blasting machine, wear-resistant rubber belt, auger, elevator, separator, feed conveyor, dust collector and cleaning machine. The hook shot blasting machine is equipped with an automatic shutdown device, which is easy to operate.
The main uses of the hook shot blasting machine are as follows:
1. Hook type shot blasting machine can generate compressive stress on the surface of parts, improve the fatigue strength and tensile stress corrosion resistance of parts;
2. The thin-walled parts of the hook type shot blasting machine can correct deformation;
3. The shot blasting machine technology replaces the ordinary hot and cold forming technology, which can not only avoid residual tensile stress on the surface of the part, but also obtain good compressive stress for the part. It should be noted that the use temperature of the parts processed by the shot blasting machine should not be too high, otherwise the compressive stress will automatically disappear under high temperature and lose the expected effect. Their use temperature is determined by the material of the part. Generally, the service temperature of steel parts is around 260℃-290℃, while the service temperature of aluminum parts is only 170℃.
