A multi-layer diamond saw blade head

Abstract

The invention discloses a multi-layer diamond saw blade bit and belongs to diamond saw blade tools. The multi-layer diamond saw blade bit consists of cutting layers and auxiliary cutting layers, wherein the sum of the number of the cutting layers and the number of the auxiliary cutting layers is odd, the auxiliary cutting layers are made of graphite materials and have a wedge-shaped structure with the wide top and narrow bottom; the bottom edge of the planar shape is in a V shape; and the other edge of the planar shape are flush with the tool bit. The multi-layer diamond saw blade bit is simple in structure and convenient to operate, and the cutting sharpness of the saw blade can be gratly improved and the service life of the saw blade can be greatly prolonged; and moreover, the multi-layer diamond saw blade bit is widely applied to road construction, constructional engineering and stone machining.

Description

technical field [0001] The invention relates to the field of diamond saw blade tools, in particular to a multilayer diamond saw blade head. Background technique [0002] As a cutting tool, diamond saw blades are widely used in road construction, construction engineering and stone processing. The diamond saw blade is mainly composed of the saw blade substrate and diamond agglomeration welding. Diamond agglomerate, also known as diamond cutter head, is formed by mixing, pressing, molding and sintering diamond and metal powder. The cutter head is divided into single-layer and multi-layer structures. The multi-layer structure diamond cutter head has better sharpness, but the traditional multi-layer structure cutter head has the following disadvantages: First, the auxiliary cutting layer is a mixture of iron flakes, copper flakes or other metal powders, which has high cost and complicated manufacturing process The second is that there is an interface between the auxiliary cutti...

Problems solved by technology

The multi-layer structure diamond cutter head has better sharpness, but the traditional multi-layer structure cutter head has the following disadvantages: First, the auxiliary cutting layer is a mixture of iron flakes, copper flakes or other metal powders, which has high cost and complicated manufacturing process The second is that there is an interface between the auxiliary cutting layer and the cutting layer, and the degree of alloying between the layers is likely to be different because of the large difference in powder composition; the third is that the auxiliary cutting layer has a strong abrasive performance Chip removal grooves cannot be formed in time in the early stage of cutting, which affects the cutting sharpness of the saw blade; fourth, the auxiliary cutting layer is exhausted in the later stage of saw blade cutting, and the cutting layer is still not completely consumed, but continued use will damage the base of the saw blade, resulting in cutting layers of waste
