Abstract

The invention discloses a diamond saw blade for rock plate cutting and a manufacturing method thereof.The saw blade is composed of a tool bit and a base body, and the tool bit is prepared from, by weight, 20-40 parts of copper powder, 10-25 parts of tin powder, 10-30 parts of iron powder, 5-20 parts of superfine cobalt powder, 5-15 parts of nickel powder, 10-15 parts of zinc powder and 1-3 parts of graphite; wherein the volume fraction of the diamond is 10-30%, the particle size of the diamond is 120-180 microns, and the specific manufacturing method comprises the steps of burdening, mixing, cold press molding, hot press molding and subsequent treatment. Compared with similar products, the diamond saw blade for cutting the rock plate has the advantages that the sharpness is improved by 1-2 times, the service life is prolonged by 2-3 times, the cost is reduced by 20-40%, cut edges are neat, edge breakage and trailing are avoided, and the diamond saw blade has an advanced level in domestic products.

Description

technical field [0001] The invention relates to the field of powder metallurgy, in particular to a diamond saw blade for cutting rock slabs and a preparation method thereof. Background technique [0002] In the prior art, diamond saw blades are generally formulated with a cobalt-based matrix, which has stable performance and good strength and toughness, but the cobalt raw material is expensive, resulting in a higher cost of the saw blade. At the same time, common saw blades for cutting rock slabs on the market still have slow cutting speed, short service life, poor cutting edges, and tailing. Contents of the invention [0003] The purpose of the present invention is to provide a diamond saw blade for rock slab cutting and its preparation method to solve the problems of high cost, slow cutting speed, short service life, poor edge chipping and trailing of the saw blade in the prior art. The problem. [0004] To achieve the above object, the present invention provides the f...
