Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting equipment, in particular to an automatic rotating special hanger for shot blasting. Background Art

[0002] The principle of shot blasting is to use an electric motor to drive the impeller body to rotate (directly or with a V-belt drive), and by the action of centrifugal force, projectiles with a diameter of about 0.2 to 3.0 (different types such as cast steel shot, wire cut shot, stainless steel shot, etc.) are thrown onto the surface of the workpiece, so that the surface of the workpiece reaches a certain roughness, making the workpiece beautiful, or changing the welding tensile stress of the workpiece to compressive stress, thereby increasing the service life of the workpiece. By improving the finish of the workpiece surface, the adhesion of the paint film of the subsequent painting of the workpiece is also improved. The shot blasting process is used in almost most fields of machinery, such as shipbuilding, auto parts, aircraft parts, gun and tank surfaces, bridges, steel structures, glass, steel plate profiles, anti-corrosion of the inner and outer walls of pipelines, and even road surfaces.

[0003] The principle of the hanging shot blasting machine is that the workpiece to be shot blasted is directly hung on a hook or a hanger, and is manually brought to the traction system in front of the shot blasting room, and the hook automatically enters the shot blasting room. During the existing shot blasting, the steel sand not only hits the workpiece, but also continuously hits the hanger. Since the workpiece is hung on the hook, the weight of the hook will increase. Therefore, the hook for hanging the workpiece is a vulnerable part and needs regular maintenance and replacement. For this reason, we have designed a special automatic rotating hanger for shot blasting to solve the above problems. Utility Model Content
