Grinding wheel forming template

Abstract

The invention discloses a grinding wheel forming template. The grinding wheel forming template comprises a disc-shaped metal base body. A hollow hole is formed in the middle of the base body according to the specification of a grinding wheel to be formed in a pressing mode. A cavity is formed in the working face of the base body and is filled with a soft silicone rubber body. The parallel disc-shaped template is formed by the cavity and the metal base body. A metal lacing wire is welded into the cavity, and patterns are arranged on the circumferential surface of the metal lacing wire. The grinding wheel forming template is easy and convenient to manufacture, long in service life and capable of improving product quality. Because the shore hardness of soft silicon rubber is low, inner nonuniformity of forming materials can be well compensated for, good inner density uniformity and good inner hardness uniformity of a grinding wheel blank can be kept, balance performance is good, and product quality is improved. Because the density of the grinding wheel forming template is larger than that of liquid, the grinding wheel forming template does not need to be accommodated in special leather bags. The situation that grinding particles abrade substantially will not happen, the problem that a metal plate deforms after being used for a certain period is avoided, and the service life of the grinding wheel forming template is greatly prolonged.

Description

technical field [0001] The invention relates to a molding template for pressing a grinding wheel, in particular to a molding template for pressing a ceramic grinding wheel. Background technique [0002] As we all know, grinding wheel pressing is a very important link in the grinding wheel manufacturing process, which has a great impact on product quality. At present, most grinding wheel manufacturers use metal plates as the upper and lower templates for pressing and forming. However, due to the unavoidable phenomena of uneven feeding and spreading during the production process, and the metal templates are difficult to press due to their high rigidity. The upper and lower surfaces of the produced grinding wheel blank are flat, which will lead to quality problems such as uneven hardness, uneven density, and imbalance, and even waste products. Especially when manufacturing grinding wheels with larger diameter (D≥400mm) and thinner thickness (T≤40mm), the effect is more obvious...
