Brief introduction of shot blasting machine
Shot blasting cleaning machine is to use high-speed rotating impeller to throw the shot at the rotating workpiece in the drum, so as to achieve the purpose of cleaning the workpiece. Suitable for sand cleaning, derusting, descaling and surface strengthening of castings and forgings under 0/5 kg in various industries.
The main uses of shot blasting machine are as follows:
① Shot blasting machine produces compressive stress on the surface of parts, which can improve their fatigue strength and tensile stress corrosion resistance;
② Shot blasting machine can correct twisted thin-walled parts;
(3) The shot blasting machine technology replaces the general cold and hot forming technology to form large thin-walled aluminum parts, which can not only avoid residual tensile stress on the surface of the parts, but also obtain favorable compressive stress. It should be noted that the service temperature of the parts processed by shot blasting machine should not be too high, otherwise the compressive stress at high temperature will disappear automatically, thus losing the expected effect. Their service temperature is determined by the material of the parts, and the service temperature of ordinary steel parts is about 260℃. At 290℃, the aluminum part is only 170℃.
