Abstract
The invention discloses a method for manufacturing a super-hard composite cutting blade. Firstly, carbide alloy or high-speed steel sheets prepared to be a base seat of the cutting blade is proceeded the treatment of drilling prepared forming openings, thereby prepared forming openings are formed. Secondly, super-hard materials and composite powder are directly added into the inner of the prepared forming openings under the protection of a sintering mold, and the materials installed inside the prepared forming openings are transformed into super-hard polycrystalline materials after being sintered under high temperature and high pressure. Thirdly, the demanded size of the cutting blade is made by cutting along the centre of the prepared forming openings, the super-hard polycrystalline materials installed inside the original prepared forming openings b a cutting tip, and the carbide alloy or high-speed steel sheets mounted between each prepared forming opening is used as a cutting base body. The invention resolves problems of un-solid welding, easy peeling and high manufacture cost of an integral tool-holder super-hard cutter of the existing super-hard composite cutting blade. The invention not only increases the rigidity of the composite super-hard cutters, but also greatly reduces the using amount of super-hard material powder, and lowers the manufacture cost.
Description
Technical field
The present invention relates to a kind of cutter manufacture method, especially relate to a kind of method for manufacturing ultra-hard composite blade.
Background technology
Diamond, cubic boron nitride are two kinds of the highest materials of hardness in the world, and wherein diamond hardness in all known substances is the highest, and cubic boron nitride hardness is only second to diamond, but its hear resistance and higher to the chemical stability of ferrous metal.Have good serviceability by superhard material powder and a small amount of bond through the superhard glomerocryst material that the HTHP sintering forms, be widely used in the machining tool field.But present superhard glomerocryst composite blade all adopts carbide alloy substrate and cutter hub welding method, and this method welding fastness is not enough, and ultra hard material layer is thin, can only be used for the fine finishining field.Though and monoblock type machine folder superhard cutter can be used for roughing and semifinishing, because the superhard material consumption is big, cost is higher, makes to use to be restricted.。
Summary of the invention
Purpose of the present invention just is at superhard glomerocryst composite blade not prison welding, easily comes off, and the high problem of monoblock type machine folder superhard cutter production cost, make superhard glomerocryst composite blade by adopting the once sintered method in preformed hole, both improved the intensity of compounded superhard cutter, can significantly reduce simultaneously the consumption of superhard material powder, reduce production costs.Thereby provide a kind of method for manufacturing ultra-hard composite blade of better effects if.
Purpose of the present invention can realize by following measure:
Manufacture method of the present invention is as follows: the carbide alloy or the high speed steel plate that at first will prepare as the blade pedestal bore the processing of preformed hole, form the preformed hole, directly adding superhard material and bond powder under the protection of sintering mold then in preformed preformed hole, superhard material and bond powder are converted into superhard glomerocryst material in the preformed preformed hole by making behind the HTHP sintering; The size in the preformed hole of boring and spacing will be made the shape and the specification of blade according to drawing up and determine, and then can be made into needed blade specification along preformed hole heartcut, promptly become point of a knife through superhard glomerocryst material in the preformed hole original after the above-mentioned cutting, carbide alloy between each preformed hole or high speed steel plate then are blade base, and then, promptly make the superhard glomerocryst composite blade of one-shot forming through mill processing, the operation of putting the first edge on a knife or a pair of scissors.
Two sides, preformed hole is the back draught groove among the present invention, also can be other suitable shapes.Superhard material is any one or two kinds of combinations in diamond, the cubic boron nitride; Bond is selected from any one or a few in aluminium nitride, titanium nitride, molybdenum nitride, magnesium nitride, zirconium nitride, chromium nitride, tungsten nitride, alundum (Al, cobalt, molybdenum, titanium, iron, aluminium, nickel, copper, tungsten, the chromium.Carbide alloy or high speed steel plate (2) thickness are 1-100mm, also can be other suitable dimensions as required.
The present invention has solved existing superhard glomerocryst composite blade not prison welding, has easily come off owing to adopt said method, and the high problem of monoblock type machine folder superhard cutter production cost.Both improved the intensity of compounded superhard cutter, can significantly reduce the consumption of superhard material powder simultaneously, reduced production costs.
