Embodiment 1

[0016] refer to figure 1 , figure 2 The weakened carcass is positioned in an orderly manner to form multiple groups of gear-shaped diamond saw blades, including the saw blade matrix 1 and the nodes 2. The segment 2 is formed by sintering the working layer sheet 6 and the intermediate layer sheet 7, and the working layer sheet 6 is distributed with weakened carcass particles 3 arranged in an orderly manner. After sharpening and working saw blade, diamond particles 4 protrude from the edge, the weakened carcass particles automatically fall off and pits 5 appear, the intermediate layer 7 is worn out in advance to form grooves, and the saw blade automatically forms multiple sets of gear-shaped working surfaces. The diameter of the saw blade is Φ500mm, the size of the working layer in the block: length × height × thickness = 40mm × 10mm × 0.3mm; the size of the interlayer sheet: length × height × thickness = 40mm × 10mm × 0.2mm, each segment contains 7 layers of working layers a...

Abstract

The invention discloses a multi-set-gear-shaped diamond saw blade self-formed by orderly positioning and weakening of carcasses and a manufacturing process of the saw blade. The saw blade is composedof segments and a base body, and the segments are formed by compounding working layer sheets and middle separation layer sheets, wherein the thicknesses of the working layer sheets and the middle separation layer sheets are 0.2-2.0 mm. Segment working layers are made of metal powder and diamond, separation layers are made of graphite powder, ceramic powder and copper-tin alloy powder, organic solvents are added to the working layers and the separation layers, and the working layers and the separation layers are manufactured into working layer sheet blanks and middle separation layer sheet blanks separately; weakened carcass particles are embedded in predetermined positions with pit structures of the working layer sheet blanks, and then the working layer sheets and the middle separation layer sheets are alternately assembled at intervals and sintered into the segments of the saw blade; and the segments are welded to the base body to manufacture the saw blade with a diameter of 100-2500mm. In the cutting working process, the weakened carcass particles fall off automatically, the middle separation layers are worn in advance, pits and grooves are formed in working lip planes of the segments, so that the working plane of the saw blade is of a multi-set-gear-shaped structure, and the saw blade has the advantages such as high efficiency, long life and low energy consumption.

Description

technical field [0001] The invention belongs to the field of saw blades and their manufacturing techniques, and relates to mechanical processing and powder metallurgy. The powder metallurgy hot-pressing sintering technology is used to form multiple sets of gear-shaped saw blades. Background technique [0002] The existing general-purpose welded diamond saw blades have problems such as wide slits, large resistance, high energy consumption, and low efficiency during the sawing process due to the large width of the working surface of the nodes. Starting from changing the working mode of the welded diamond saw blade cutting broken materials, the diamond saw blade with multiple sets of gear-shaped working surface structures that weaken the matrix material particles with an orderly positioning and distribution structure can effectively reduce the gap between the working surface and the processed material. The contact area greatly improves the sharpness of the saw blade, which is b...
