Production system and production method of resin grinding wheel and resin grinding wheel

Abstract

The invention discloses a production system of a resin grinding wheel. The production system of the resin grinding wheel comprises a bearing unit, a mold unit, a feeding unit, a scraping unit, an upper net piece unit, an upper ring unit, a paper feeding unit, a heating unit, a repoussage unit and a pressing unit, the feeding unit comprises a disc body and a vibration mechanism arranged below the disc body, the disc body is used for containing raw materials, the disc body is provided with a flow choking assembly, the flow choking assembly extends into the disc body and makes contact with the raw materials in the disc body, and the flow choking assembly is used for stirring the raw materials when the raw materials vibrate along with the disc body. The invention correspondingly provides a production method and the resin grinding wheel obtained through the production method. According to the production system of the resin grinding wheel, the situation that grinding materials and powder are layered is avoided, the production quality of the grinding wheel is guaranteed, the mesh does not need to be highly heated and softened, the flatness of the surface of the grinding wheel is guaranteed, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of grinding wheels, and in particular relates to a production system and a production method of a resin grinding wheel and the resin grinding wheel. Background technique [0002] Resin grinding wheel is a grinding wheel made of resin with high strength. It is used in cutting discs, double-end faces, heavy-duty grinding wheels, polishing wheels, etc. It has a certain degree of elasticity, low heat resistance, good self-sharpening, easy production, and short process cycle; it is widely used in rough grinding, rough grinding, cutting and free grinding, such as grinding steel ingots, deburring castings, etc. [0003] During the production of resin grinding wheels, manual batching is generally carried out according to the proportion of raw materials required by different products.

Problems solved by technology

[0003] During the production of resin grinding wheels, manual batching is generally carried out according to the proportion of raw materials required by different products, the abrasive is added to the mixer, and then liquid phenolic resin is added to evenly moisten the grinding wheel. After wet grinding, enter the next mixer, add powdered resin and additives, continue to mix until uniform, and form the mixture required for production, that is, the raw material; after the raw material is prepared, it enters the molding process, and molding is the most important part in the production process of resin grinding wheels. The important links generally include the steps of laying net, feeding raw materials, heating and pressing. The current molding equipment, when in use, transports raw materials through conventional spiral vibrating feeding trays. In the case of relatively large abrasives, The conveying process of raw materials is in normal operation. However, when producing grinding wheels with relatively low abrasives, due to the vibration process, the raw materials will be separated from the abrasive and powder in the vibrating disc, which will have a serious impact on the quality of the product. ; Moreover, since some grinding wheels need to be in a concave state at the center core ring to adapt to the assembly of the corresponding equipment, the shape of the grinding wheel is like Figure 1, the mold needs to have the same concave shape. Since the glass fiber mesh is relatively hard, in order to press down the glass fiber mesh, It is necessary to bake the glass fiber mesh for a long time, which leads to the fact that the surface of the metal plate is easy to stick to the raw materials in the mold when it is pressed down, resulting in an uneven surface, and the raw material layer sinks with the middle of the mold shape, making it difficult for the scraper to clean the surface. There is a certain degree of difficulty in production due to smooth processing
