Abstract
The utility model relates to a diamond thin circular saw blade used for the glass cutting process, which comprises a disc substrate and a cutter body fixed on the periphery of the substrate. A plurality of convex edges are uniformly distributed on the upper edge of the periphery of the substrate; the convex edges consist of convex wedges, grooves and reinforced ribs; the convex wedge is arranged between two adjacent grooves; the reinforced rib is arranged between the root of the convex wedge and the bottom part of the groove; and drop pits are arranged on the two side surfaces of the convex edge. The diamond thin circular saw blade adopts the structure that convex edges are arranged in the position on which the substrate is fixedly connected with the cutter body, and the drop pits on the surfaces of the convex edges form uneven shapes, to ensure that the cutter body can be firmly and oppositely covered on the substrate, thereby the diamond thin circular saw blade has the advantages that the surface area of the convex edge is increased, the fixedly connected area between the cutter body and the substrate is increased, and the connecting rigidity and the connecting reliability of the cutter body and the substrate are enhanced.
Description
Technical field
The utility model relates to a kind of diamond saw blade, and particularly a kind of sintered type slim diamond blade can be widely used in the cutting of crisp hard material, is particularly useful for the mill of cutting of glass.
Background technology
Along with the development of society, the progress of science and technology, particularly glass processing industry of many industries has improved the cutting processing required precision of product, particularly the raising that material damage, life-span, cutting efficiency are required.At present, the cutting processing instrument of crisp hard material such as glass mostly adopts diamond disc, not only higher requirement has been proposed and adopt to the intensity of matrix but also to the caking ability and the firmness of matrix and cutter head than thin type circular diamond sawblade, the common configuration of existing saw blade is a fixed cutter body on the outer rim of matrix, its defective is: 1, general matrix thickness does not satisfy the requirement under the ultra-thin condition more than 1mm; 2, matrix combines insecurely with cutter hub, is difficult to reach requirements such as material damage, life-span.
Summary of the invention
The purpose of this utility model is for overcoming the deficiencies in the prior art, providing a kind of matrix to combine the glass that is used for firm and that intensity is high with cutter hub and cut the thin saw blade of diamond that mill is processed.
The technical solution adopted in the utility model is: comprise plate-shaped base body, be fixed on the cutter hub on the matrix outer rim, being uniformly distributed along the circumference on the matrix outer rim, several are protruding stupefied, protruding stupefiedly form by protruding wedge, groove and reinforcement, protruding wedge is arranged between the two adjacent grooves, be provided with reinforcement between protruding wedge root and groove bottom land, pit is covered with on protruding stupefied both side surface.
The utility model is provided with protruding stupefied at the fixing position of matrix and cutter hub, the pit on protruding stupefied surface forms rough shape, can make cutter hub securely left-hand thread on matrix, increased protruding stupefied surface area, strengthened cutter hub and matrix affixed, the rigidity and the reliability that are connected between cutter hub and matrix have been improved.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is the structure chart of matrix 2 among Fig. 1;
Fig. 3 is the middle cutaway view of Fig. 2;
Fig. 4 is the partial enlarged drawing of Fig. 2 convexity stupefied 3.
The specific embodiment
Shown in Fig. 1～4, circular cutter hub 1 is fixed on matrix 2 outer rims of band installing hole in the form of annular discs, and the external diameter of matrix 2 is that 100-250mm, thickness are 0.5-1.2mm.Cutter hub 1 is mixed by metal dust and diamond particles after Thermocompressed sintering and forming, and matrix 2 and cutter hub 2 sintering are together.On matrix 3 outer rims, be uniformly distributed along the circumference several protruding stupefied 3, protruding stupefied 3 are made of protruding wedge 5, groove 4 and reinforcement 6, groove 4 is arranged between the two adjacent protruding wedges 5, also is that protruding wedge 5 is arranged between the two adjacent grooves 4, and reinforcement 6 is arranged between protruding wedge 5 roots and groove 4 bottom lands.Protruding stupefied 3 thickness is 0.5mm, and the width 5-7mm of protruding wedge 5, the width of reinforcement 6 are 0.1-0.3mm.Handle through laser roughening protruding stupefied 3 both sides, and the surface forms pit 7, and pit 7 is covered with one by one on protruding stupefied 3 both side surface, and the diameter of pit 7 is 0.5-1.2mm, and this uneven structure that protruding stupefied 3 surface forms makes cutter hub 1 and matrix 2 firm engagement.
Claims (3)
