Cold pressing preparation process for resin grinding wheel

Abstract

The invention relates to a cold pressing preparation process for a resin grinding wheel. A bottom plate, supporting frames and a material injection device are included. The supporting frames are evenly installed at the upper end of the bottom plate, the material injection device is installed between the upper ends of the supporting frames, and the material injection device is located in the middle of the upper portion of the bottom plate. According to the cold pressing preparation process for the resin grinding wheel, the problems that when existing equipment stirs and mixes raw materials, the mixing effect is poor, mixing is not uniform, the mixed raw materials cannot be effectively screened, powder balls are likely to be generated after mixing, meanwhile, when the existing equipment injects the mixed raw materials, the injection effect is poor, injection is not accurate, the injected raw materials cannot be effectively controlled, the sizes of formed grinding wheels are different, and the subsequent use effect of the grinding wheels is influenced are solved.

Description

technical field [0001] The invention relates to the field of grinding wheel processing, in particular to a cold-pressing preparation process of a resin grinding wheel. Background technique [0002] Resin grinding wheel is a grinding wheel made of resin. The resin grinding wheel has high strength and can add reinforced fiber mesh and steel bars to the grinding wheel, such as cutting discs and grinding discs. Most of our resin grinding wheels are not waterproof and cannot be ground with grinding fluid. , Of course, there are also some resin grinding wheels that need to be ground with grinding fluid, such as epoxy, resin grinding wheels have a good grinding finish, and the workpiece is not easy to burn. Resin grinding wheels are used in cutting discs, double-end faces, heavy-duty grinding wheels, polishing wheels, etc. etc., the strength of resin bond grinding wheel is lower than that of metal bond and vitrified bond. [0003] At present, the existing resin grinding wheels usu...

Problems solved by technology

[0005] The invention can solve the problem that the existing equipment has poor mixing effect and uneven mixing when stirring and mixing the raw materials, and cannot effectively sieve the mixed raw materials, which leads to the phenomenon that powder lumps are easily produced after mixing. At the same time, the existing When the equipment is used to inject the mixed raw materials, the injection effect is poor, the injection is not accurate, and the injected raw materials cannot be effectively controlled, resulting in different sizes of the formed grinding wheel, which affects the subsequent use of the grinding wheel, etc. problem
