Description
Technical Field
[0001] The utility model relates to the technical field of shot blasting, in particular to a shot blasting device. Background Art
[0002] In today's steel structure production process, it is often necessary to shot blast the steel structure. Shot blasting is a cold treatment process, which is divided into shot blasting cleaning and shot blasting strengthening. Shot blasting cleaning, as the name suggests, is to remove impurities such as surface oxide scale to improve the appearance quality. Shot blasting strengthening is to use high-speed projectiles (60-110m / s) to continuously impact the surface of the workpiece to be strengthened, forcing the target surface and surface layer (0.10-0.85mm) to undergo the following changes during the cyclic deformation process: 1. The microstructure is modified; 2. The non-uniform plastic deformation surface layer introduces residual compressive stress, and the inner surface layer produces residual tensile stress (Ra Rz), which can improve the fatigue fracture resistance of steel components, prevent fatigue failure, plastic deformation and brittle fracture, and improve fatigue life; 3. The roughness of the outer surface changes, which is convenient for spraying paint. There are many shot blasting devices on the market today, including some shot blasting devices that can recycle glass beads or steel shots for shot blasting, thereby reducing the loss of shot blasting materials. However, after shot blasting, the recycled shot blasting materials are often mixed with metal debris, rust, defective shot blasting materials and other impurities, which will affect the effect of shot blasting again. Therefore, a new shot blasting device that can remove impurities in the shot blasting material to be recycled is needed. Therefore, the present application provides a shot blasting device to meet the demand. Utility Model Content
