Abstract

The invention discloses a high-strength and low-noise diamond circular saw web base body which comprises a saw web base main body. A central hole is formed in the center of the saw web base main body. Semi-permeable water grooves which are evenly distributed at intervals are formed in the outer circle of an upper radial face and the outer circle of a lower radial face of the saw web base main body. The depth of the semi-permeable water grooves is half of the thickness of the saw web base main body. Saw teeth formed between every two adjacent semi-permeable water grooves are respectively provided with a tool bit. All the tool bits on each radial face form a circle; in other words, the upper radial face and the lower radial face of the whole base main body are respectively provided with one circle of tool bits. The high-strength and low-noise diamond circular saw web base body has the advantages that an auxiliary support is added, and therefore cut-in stability is improved; the water grooves are semi-permeable water grooves, and therefore the cut-in thickness of the tool bits is halved, and cut-in impact is reduced; the saw tooth force bearing is optimized, and fatigue life is prolonged; the modal density of the diamond circular saw web base body is lowered, and radiation noise is reduced.

Description

technical field [0001] The invention relates to a high-strength and low-noise diamond circular saw blade substrate, which belongs to the technical field of cutting tools. Background technique [0002] Diamond circular saw blades are widely used in the cutting of stone, ceramics, concrete, etc. The traditional diamond circular saw blade substrate such as Figure 4 As shown, there are evenly distributed serrations on the outer circle, and there is a "U" or "R" penetrating water groove between each serration. Periodic cutting in and out of sawtooth is an intermittent machining process, which bears a large impact during the cutting process, the cutting process is unstable, the stress at the root of the tooth is concentrated, and fatigue cracks are prone to occur. In addition, the water tank cuts off the outer circumference of the saw blade, so that the n=ks / 2 or n=ks (k=1,2,3...) pitch mode of the matrix is ​​split, increasing the modal density of the matrix and increasing the ...
