Abstract
An ultra-hard material saw blade is mainly characterized in that sawteeth are arranged on a saw blade base body; and the sawteeth adopt ultra-hard material cutting blades; or the sawteeth are arranged on the saw blade base body, and the ultra-hard material cutting blades are arranged on the edge of the sawteeth. The ultra-hard material cutting blade is selected from diamond composite blade or cubic boron nitride composite blade according to requirement. The saw blade base body adopts a frame saw blade base body or a band saw blade base body to form a frame saw blade or a band saw blade. The prior hard alloy saw blade can not meet the practical requirement for cutting high-hardness difficult-to-cut materials. The ultra-hard material saw blade is low in cost, and can be used for cutting high-hardness difficult-to-cut materials. In addition, the service life of the ultra-hard material saw blade is higher than that of the hard alloy saw blade by more than ten times or even tens of times.
Description
Technical field
The utility model relates to a kind of sawing metal and the nonmetallic sawing cutlery of sawing.
Background technology
At present, the saw of home and abroad saw industry institute production and marketing has two big classifications: a class is a saw blade, promptly is shaped on the saw of several sawtooth at the disk periphery, and saw blade is located with the hole, and is installed in and carries out sawing workpieces on the saw blade lathe.Another kind of is saw blade, saw blade divides frame saw blade and bands for band again, frame saw blade is not only thin but also long, the symmetry of hump is shaped on the saw of several sawtooth on one side, this saw is installed in and carries out sawing workpieces on the buck saw lathe: bands for band is not only thin but also long, one side of hump symmetry is shaped on the band saw of several sawtooth, is installed in to carry out sawing work on the band saw lathe.
Appearance along with superhard material, diamond compact (PCD) and cubic boron nitride composite sheet (PCBN) superhard material blade, on saw blade, be applied, it has high red hardness, be high speed fine finishining or semi-finished ideal material, the wearability height, long service life, comprehensive benefit is good, but cost is relatively more expensive, go up to use at saw blade (frame saw blade and bands for band) to be restricted, so in the saw blade industry, the frame saw blade and the bands for band of PCD, PCBN superhard material also do not appear in market at home so far.
The blade major part of using on the cutter market is a carbide chip now, or carbide surface scribbles the indexable carbide chip of one or more layers titanium carbide (Tic), titanium nitride (Tin), alundum (Al superhard materials such as (Al2O3).But above-mentioned saw blade can not satisfy the sawing high rigidity, the actual needs of difficult-to-machine material.A kind of saw blade made from steel disc appears on the market, be coated with one deck diamond dust on its surface, perhaps add diamond dust in when cutting in saw kerf, utilize the building materials such as active force cutting marble of friction, this saw blade can not substitute the effect that saw blade that superhard material makes can play at all.Provide that a kind of cost is low, the saw blade of superhard material, become the present problem that solves of needing.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provide a kind of cost low, can be improved tens times to tens times superhard material saw blade the service life of sawing than existing carbide alloy saw blade
The technical solution of the utility model is to implement like this: be arranged with sawtooth on the saw blade matrix, sawtooth is the superhard material blade.
The technical solution of the utility model can also for: be arranged with sawtooth at the saw blade matrix, the superhard material blade arranged at the land place of sawtooth.
Superhard material blade of the present utility model is selected diamond composite blade or cubic boron nitride composite blade as required respectively.The matrix material of saw blade should be selected alloy spring steel or other steel of the different trades mark according to different requirements.
Superhard material is meant diamond and cubic boron nitride.Natural diamond (ND) is the hardest material of occurring in nature, the hardness of cubic boron nitride (CBN) is only second to diamond, the diamond overwhelming majority in industrial application is man-made polycrystalline diamond (PCD), but, diamond is that the cutter hub that can't be welded to cutter with the method for welding gets on, so the diamond blade of now using on cutter all is to adopt the diamond composite blade, what is meant by diamond compact (PCD)? as its name suggests, the diamond compact that the tungsten carbide chip (a kind of hard metal tip) that exactly that one deck is relatively thin man-made polycrystalline diamond and thickness are thicker is sintered into one under HTHP, the purpose of doing like this has two, the one, in order to save high diamond cost, the 2nd, tungsten carbide chip have can be integrally welded with the steel body processing performance.
Though diamond is very hard, non-ferrous metals such as its only suitable cutting or cutting nonferrous metal, nonmetal, titanium alloy, aluminium alloy and copper alloy.Be only second to adamantine cubic crystal boron nitride so produced a kind of hardness again, be called for short boron nitride (CBN), it is fit to cutting or cuts various glass hard steels and high rigidity iron very much, it is the same with diamond, just can be welded on the matrix of cutter after only making cubic boron nitride composite sheet (PCBN).
Superhard material blade (diamond composite blade or cubic boron nitride composite blade) arranged orderly be fixedly welded on the saw blade matrix or the land place of sawtooth, form different tooth pitches (s), the saw blade of the different different back of tooth of tooth depth (h) and different chip pocket types, this its profile of tooth of saw blade sawtooth is flat tooth, or profile of tooth is a left and right tooth.
The said saw blade matrix of the utility model is the frame saw blade matrix, or the bands for band matrix, forms superhard material frame saw blade or superhard material bands for band.
Because diamond compact and cubic boron nitride composite sheet price are more many than carbide chip costliness, the utility model installs diamond compound (PCD) superhard material blade and cubic boron nitride compound (PCBN) superhard material blade additional on the saw blade matrix, the saw blade of making, cost is reduced greatly, than improving tens times to tens times the service life of existing carbide alloy saw blade, can fill up the blank of still not having the superhard material saw blade in this field, satisfy the actual needs of sawing high rigidity difficult-to-machine material.
