The present invention solves the problem of multilayer segments of diamond tools, and greatly improves the service life of the segments of diamond tools. In the present invention, the diamond abrasive grain is orderly arranged during the hot pressing sintering process, the total advantages of soldering diamond product are obtained; the procedure is easy to realize automatization. The present invention can be used for all the products of hot pressing sintering diamond, such as circular saw blade, drill bit, band saw, barrel saw, rope saw and grinding head, etc,.
Description
Technical field
The present invention relates to the hard brittle material manufacture field, be specifically related to a kind of diamond tool, be widely used in high rigidity crystal, stone material such as single (many) crystal silicons and cut, and glass, pottery, jewel, machining graphite industry.
Background technology
Present existing diamond tool can be divided into individual layer usually and electroplate and multi-layer sintering (comprising heat cure) two big classes, because the diversity and the complexity of actual grinding operation, individual layer and multilayer instrument have his own strong points, and wherein the individual layer plating diamond tool is made easily because electroplating technology is simple; Need not to repair dressing, easy to use, therefore in the production application of diamond tool all always in occupation of very big share.But owing to all do not exist firm chemical metallurgy to combine on the interface of coated metal and the abrasive material and the grinding tool matrix of electro-deposition on the plating diamond tool.Abrasive material just mechanically is embedded between coating and the matrix, so the coat of metal is little to the hold of diamond abrasive grain, as easy as rolling off a log because of abrasive material come off and coating peel off the global failure that causes emery wheel in flakes.In addition, because coating is thick, the abrasive material proud exposure is low, and chip space is little, is easy to during the electroplating abrasion wheel grinding lose efficacy because of the adhesion obstruction of smear metal.Simultaneously, the effective rate of utilization of abrasive material itself is also extremely low on the electroplating abrasion wheel.
Abroad begin one's study in the early 1990s and replace electroplating Development of New Generation single layer soldering diamond tool with soldering, by high temperature brazing make that solder dissolves on diamond abrasive grain and metallic matrix interface, thereby the interaction of diffusion, chemical combination and so on improves the hold of matrix to diamond abrasive grain, improves the bond strength between abrasive material, bond (brazing filler metal alloy), the matrix three.The diamond brazing technology, can realize diamond, bond and metallic matrix surface chemistry metallurgical binding, has higher binding strength, very thin bond thickness, high exposed height, realize adamantine making full use of, improved the life-span and the working (machining) efficiency of instrument, changed electroplating deposition and the not high characteristics of thermal pressing sintering diamond hold in the past.Brazed diamond tool generally comprises metallic matrix, metal joint piece and diamond abrasive grain, metal joint piece is fixed on the week edge of metallic matrix, the diamond abrasive grain soldering is on the both ends of the surface of metal joint piece, this brazed diamond tool, diamond abrasive grain generally all is a single layer soldering, its working lining has only one deck, and service life is shorter.
Summary of the invention
But the purpose of this invention is to provide long brazing-thermal pressing sintering diamond tool sectional block of a kind of multi-layered brazing, service life.
Technical scheme of the present invention is such: brazing-thermal pressing sintering diamond tool sectional block, comprise diamond abrasive grain and metal tube, above-mentioned diamond abrasive grain is arranged and is fixed together with the metal tube soldering along the length direction of metal tube in above-mentioned metal tube, soldering has the metal tube of diamond abrasive grain to be fixed together by the bond hot pressed sintering in the complex root aforementioned tube, and the mouth of pipe direction unanimity of above-mentioned each metal tube.
Above-mentioned complex root metal tube is spaced the several column that becomes to be parallel to each other, and the metal tube in each row is closely arranged mutually.
Above-mentioned several column metal tube is arranged in square joint piece.
Above-mentioned several column metal tube is arranged in fan-shaped joint piece.
Above-mentioned several column metal tube is arranged in columned beading joint piece.
After adopting such scheme, brazing-thermal pressing sintering diamond tool sectional block of the present invention, the method that has adopted hot pressed sintering to combine with soldering, diamond abrasive grain is arranged in metal tube and along the length direction of metal tube by solder brazing, each metal tube is fixed together by the bond hot pressed sintering, and the mouth of pipe direction unanimity of each metal tube has successfully solved the problem of multi-layered brazing diamond block, the service life of having improved diamond tool sectional block greatly.The present invention has carried out orderly arrangement to the diamond abrasive grain in the hot pressed sintering in fact exactly, have simultaneously whole advantages of braze welding diamond product again, and production process easily realizes automation, can be in all over products of thermal pressing sintering diamond, as circular saw bit, drill bit, band saw, bucket saw, rope saw and bistrique etc.
