Detailed description of the invention

In order to explain the technical solution of the utility model further, below in conjunction with accompanying drawing, by specific embodiment, the utility model is elaborated.

The utility model provides a kind of high sharp high abrasion impact-resistant diamond block, comprise saw bit matrix and the some diamond blocks being located at saw bit matrix radial outside, diamond block is hexahedron structure, in it, the vertical saw bit matrix radial direction in outer face, inner face and outer face are the cambered surface centered by the saw bit matrix center of circle, wherein inner face and saw bit matrix Joint, outer face is as the cutting edge of diamond block, upper surface and lower surface correspond to the upper of saw bit matrix, lower surface, left surface and right flank lay respectively at above-mentioned inner face outer face, the both sides of upper surface and lower surface, left, right flank is rectangle, on diamond block, the mid portion of lower surface is step-like, middle low, two ends are high, and it is highly identical, the area that two ends higher part is divided accounts for 50% to 70% of this surface area, the diamond grit that diamond block mid portion uses is greater than the diamond grit that two ends use.As shown in Figure 1, outer face 1,2 surface band certain radian, left and right side 5,6 are rectangular structure, during installation, for disk situation, inner face 1 and outer face 2 are the corresponding two sides perpendicular to saw bit matrix radial direction, inner face 1 and outer face 2 are all in section cambered surface of centered by the matrix center of circle, wherein inner face 1 and saw bit matrix Joint, outer face 2 is as the cutting edge of diamond block, upper surface 3 and lower surface 4 correspond to the upper and lower surface of saw bit matrix, and upper surface 3, the mid portion of lower surface 4 is step-like, middle low, two ends are high, and it is highly identical, left surface 5 and right flank 6 lay respectively at above-mentioned inner face 1 outer face 2, the both sides of upper surface 3 and lower surface 4, the area that two ends higher part is divided accounts for 50% to 70% of this surface area, the diamond grit that diamond block mid portion uses is greater than the diamond grit that two ends use, the diamond order number scope that diamond block mid portion uses is 30 ~ 40, and the diamond order number scope that two ends use is 50 ~ 70.

As shown in Figure 1, innovative point of the present utility model is: the overall two ends of diamond block are the diamond that granularity is little, and centre is the diamond that granularity is large, and diamond block brait order number used is between 30 to 40, and fine diamond order number is between 50 to 70; Upper and lower surperficial 3,4 of diamond block is the middle structure having one section of lower step, the higher area in two ends account for joint block this on the surface area 50% to 70%.When adopting the saw blade work of the utility model diamond block, joint block cutting edge front end 7 first crushes cutting object, due to the impulsive force produced when fine-grained diamond can effectively disperse to cut, alleviate the consume of cutter head front end, the diamond that mid portion is thicker simultaneously when secondary shreds the abrasive dust of front end cutter head generation, effectively can improve sharpness and chip removal efficiency; Meanwhile, the upper and lower surface of diamond segment is designed to centre has a lower step, the frictional force of effective less diamond segment in cutting, improves chip removal efficiency and sharpness.
