[0002] As the standard model of shot blasting machine, the hook shot blasting machine is an ideal cleaning and strengthening equipment, and it is easy to operate. You only need to load the workpiece to be processed onto the machine and press the start button. After a very short time, the entire cleaning process is completed and all dust and residual shot are removed. It is mainly suitable for the surface treatment of various medium and large castings, forgings, weldments, and heat-treated parts, including fragile and irregularly shaped workpieces. It is suitable for the surface cleaning or strengthening of multi-variety, medium and small batches of castings, forgings and riveted welded parts, especially the surface cleaning or strengthening of slender thin-walled parts that collide. In the production process of manhole covers, shot blasting machines are required to clean and process the cast manhole covers. The existing hoisting shot blasting machines mostly fix the castings by binding with steel wires, etc., while the round manhole covers are not easy to be tied and fixed, and the stability is poor. In addition, the ordinary bundling method will cause too much obstruction on the surface of the manhole cover, resulting in the manhole cover surface cannot be cleaned, and it cannot be stably rotated during the processing, which has a certain impact on the processing efficiency of the manhole cover.
