Background technology
At present, the diamond cut blade of domestic production (also claiming diamond disc) mainly is divided into three major types, it is resinoid bond diamond cut blade, metal-bonded diamond cutting blade and electroplated diamond cutting blade, wherein resinoid bond diamond cut blade is eliminated by market because of service life is short, begin the metallic bond blade from the nineties and become each scientific research, the object of production division's research and development, but up to the present, can only the metal-bonded diamond cutting blade of production matrix thickness more than 1mm, it is mainly used in the cutting processing of building stone and optical glass blank blanking, development along with society, the progress of science and technology, in many processing industries, particularly optical glass and jewel Precision Machining industry, the metal-bonded diamond cutting blade is also used, but for the high finished product cutting processing of requirement on machining accuracy, particularly material is decreased, life-span, the cutting efficiency finished product that has higher requirements adds man-hour, be difficult to satisfy above-mentioned requirements, being embodied in because of blade is thicker makes material decrease increasing, material decrease greatly to processing more valuable can directly cause the generation of higher material cost as the material of bijouterie, approach the ultra-thin blade of formula and adopt, not only there are higher requirement of strength but also matrix itself also need have certain elasticity to matrix, simultaneously in machining accuracy to cutter hub, cut intensity and certain requirement is all arranged service life, therefore manufacture difficulty is very big, Chinese patent CN2601807Y discloses a kind of superthin diamond circular saw web, comprise cutter head, matrix, described matrix and cutter head sintering are together, cutter head is annular, be equipped with parabolic type or linear pattern boss on two face, matrix is an annular, annular pedestal outer is provided with decorative pattern, this decorative pattern cooperates with cutter head, increase bonding strength, on matrix, also be provided with thin flange.The purpose of this technical scheme provides long diamond disc of a kind of sturdy and durable, sharp, life-span.Show by technique scheme, it realizes mainly by being arranged on the thin flange on the matrix and realizing along the decorative pattern that is provided with on the pedestal outer robust purpose, but the said base outer is at described decorative pattern shape structure and how link to each other with cutter head and improve intensity and do not propose concrete technical scheme.
Summary of the invention
The purpose of this utility model is to provide the diamond cut blade that combines firmly and be applicable to precision, valuable part processing between a kind of intensity height, blade base and cutter hub at above-mentioned existing problems.
The technical solution of the utility model is:
A kind of optical glass and precision machined Buddha's warrior attendant cutting blade of jewel of being used for, the matrix that comprises band installing hole in the form of annular discs reaches and the affixed circular cutter hub of matrix, it is protruding stupefied to it is characterized in that described matrix is provided with along the plate-like outer rim, described protruding stupefied some dovetail grooves that are uniformly distributed with along the circumference, between two adjacent dovetail grooves, be provided with the protruding wedge of inverted dovetail, between protruding stupefied root and some groove bottom lands, be equipped with reinforcement, described cutter hub be compacting sintering be fixed in by dovetail groove, the protruding wedge of dovetail and reinforcement constitute protruding stupefied on.
The utility model is owing to adopted protruding stupefied with some dovetail grooves, the protruding wedge of dovetail in the setting of matrix outer rim, the reinforcement established of ring between protruding stupefied root and some dovetail groove bottom lands particularly makes protrudingly to have formed by being the matrix connection skeleton that dovetail groove, the protruding wedge of dovetail and reinforcement are formed jointly on stupefied.When cutter hub compacting burn protruding stupefied on the time, cutter hub not only can make cutter hub be fixed on the matrix by the left-hand thread function that dovetail groove has, and utilize combining of protruding wedge of dovetail and reinforcement both sides and cutter hub annular groove sidewall, strengthen affixed of cutter hub and matrix, thereby realized the fastness that is connected between cutter hub and matrix and the reliability of use.

Specific embodiments
The utility model such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 is shown a kind of optical glass and precision machined Buddha's warrior attendant cutting blade of jewel of being used for, comprise the matrix 1 of band installing hole in the form of annular discs and the circular cutter hub 2 affixed with matrix 1, it is characterized in that described matrix 1 is provided with protruding stupefied 11 along the plate-like outer rim, described protruding stupefied 11 are uniformly distributed with some dovetail grooves 12 along the circumference, between two adjacent dovetail grooves, be provided with the protruding wedge 15 of inverted dovetail, be equipped with reinforcement 13 between protruding stupefied 11 roots and some grooves 12 bottom lands, described cutter hub 2 is being fixed in by dovetail groove 12 of compacting sintering, the protruding wedge 15 of dovetail and reinforcement 13 constitute protruding stupefied 11 on.For making cutter hub 2 more firm with being connected of matrix 1, as Fig. 4, Fig. 5, shown in Figure 6, the cross section of the protruding wedge of above-mentioned dovetail also can be made into dovetail shaped wide at the top and narrow at the bottom, and dovetail groove 12 bottom lands are arranged to by two ends gradually to the arc arch shape of middle part projection, then be more conducive to strengthen cutter hub 2 and matrix 1 affixed, the same foregoing invention purpose that realizes also has dovetail groove 12 bottom land two ends to be set to by two ends gradually to the recessed arc scheme in middle part in addition.As shown in Figure 7, it mainly is to consider to increase cutter hub 2 abrasive material volumes, its purpose also is to reach the purpose that increases cutter hub 2 intensity from another angle, finish for guaranteeing that cutter hub 2 can be implemented optical glass and jewel is precision machined, promptly have certain machining accuracy and reduce the material damage to greatest extent, external diameter when matrix 1 in the utility model is 100-200mm, when thickness is 0.5-0.7, its protruding thickness of stupefied 11 is 0.1-0.2mm; Again the external diameter when matrix 1 be 100-125, when thickness is 0.4-0.5mm, its protruding thickness of stupefied 11 is 0.1-0.2mm.Adopt above-mentioned several version, can realize processing an optical lasers product parts and jewel.Need to prove on matrix 1 protruding stupefied 11 the important effect that is being connected with of the 13 pairs of cutter hubs of reinforcement that are provided with and matrix; its physical dimension also has strict demand; under normal conditions; the above-mentioned width that is located on the reinforcement 13 between groove 12 and protruding stupefied 11 roots is that 0.1-0.3mm, thickness are 0.2-0.5mm; certainly; reinforcement 13 also can will be determined the size of reinforcement 13 according to processing different parts, but the reinforcement of which kind of size all should be considered as falling into protection domain of the present utility model.
The utility model is owing to adopted protruding stupefied with some dovetail grooves, the protruding wedge of dovetail in the setting of matrix outer rim, the reinforcement established of ring between protruding stupefied root and some dovetail groove bottom lands particularly makes protrudingly to have formed by being the matrix connection skeleton that dovetail groove, the protruding wedge of dovetail and reinforcement are formed jointly on stupefied.When cutter hub compacting burn protruding stupefied on the time, cutter hub not only can make cutter hub be fixed on the matrix by the left-hand thread function that dovetail groove has, and utilize combining of protruding wedge of dovetail and reinforcement both sides and cutter hub annular groove sidewall, strengthen affixed of cutter hub and matrix, thereby realized the fastness that is connected between cutter hub and matrix and the reliability of use.
