Abstract
The present invention discloses a cutter for a metal laser cutting machine. The cutter comprises 47-54% of a calcium lanthanum chromite ceramic, 41-44% of a potassium-sodium alloy and 3-11% of a silicon rubber, wherein the calcium lanthanum chromite ceramic comprises chromium oxide, lanthanum oxide and calcium oxide. According to the present invention, the cutter has advantages of high temperature resistance, low temperature resistance, and strong air permeability.
Description
Technical field
The present invention relates to a kind of cutter for metal laser cutting machine.
Background technology
Along with the development of new technology revolution, require improve constantly machining productivity and reduce production cost., the particularly development of numerically-controlled machine, requires the new-type cutter that exploitation is higher than inserted tool cutting speed, more wear-resisting.A few days ago various high strength, high rigidity, corrosion-resistant, wear-resisting and resistant to elevated temperatures be difficult to cut novel material increasing.Estimate according to document, this kind of material oneself account for and process more than 50% of sum in the world., inserted tool to the difficult processing of wherein many novel materials with competent.On the other hand, now in the world Wimet output oneself reach 20000-25000t.The metal that annual consumption is a large amount of, as W, Co, Ta and Nb etc.The Mineral resources of these metals reduce just day by day, price increase, press spending rate a few days ago, have more than is needed decades. and some resource will exhaust.Sintex is exactly grow up in this context.
As far back as 1912-1913. Britain and Germany oneself there is alumina tool, but its application on producing then starts from nineteen fifty.Because its intensity, toughness are low, are only limitted to do continuous cutting precision work in the long term and use., and cutting speed and the amount of feed are all lower.Until 2nd generation sintex-composite alumina cutter just appears in nineteen sixty-eight, intensity and toughness are significantly improved than aluminum oxide tool, various workpiece can be cut under higher speed and the larger amount of feed. obtain and apply more widely.
Late 1970s to the beginning of the eighties world occurred the 3rd generation sintex-Silicon Nitride Ceramic Cutter.This kind of Stupalox has toughness, shock resistance, hot strength and the heat-shock resistance higher than composite alumina cutter.Ceramic tip is very fast in the increase of production of each industrially developed country.
China starts to produce composite alumina blade in batches in the sixties in 20th century, and current year output is 14-15 ten thousand.Though silicon oxide ceramics blade just begins one's study in 20 century 70s, due to poor performance, can not satisfy the demands.In recent years, along with deepening continuously to high-temperature structural ceramics area research, make the performance of silicon nitride ceramics have large increase, thus Silicon Nitride Ceramic Cutter is developed rapidly in China.
Summary of the invention
The invention provides a kind of cutter for metal laser cutting machine with high-and low-temperature resistance performance and the strong advantage of permeability.
Technical scheme of the present invention is: a kind of cutter for metal laser cutting machine, the described cutter for metal laser cutting machine is formed by Lanthanum Chromite calcium pottery, sodium-potassium eutectic and rubber composition, described Lanthanum Chromite calcium pottery comprises chromic oxide, lanthanum trioxide and calcium oxide, described Lanthanum Chromite calcium pottery occupies the 47%-54% of the overall component of cutter of metal laser cutting machine, described sodium-potassium eutectic occupies the 41%-44% of the overall component of cutter of metal laser cutting machine, and described silicon rubber occupies the 3%-11% of the overall component of cutter of metal laser cutting machine.
In a preferred embodiment of the present invention, described silicon rubber comprises Polymethyl methacrylate.
In a preferred embodiment of the present invention, described Lanthanum Chromite calcium pottery occupies 51% of the overall component of cutter of metal laser cutting machine, described sodium-potassium eutectic occupies 42% of the overall component of cutter of metal laser cutting machine, and described silicon rubber occupies 7% of the overall component of cutter of metal laser cutting machine.
A kind of cutter for metal laser cutting machine of the present invention, has high-and low-temperature resistance performance and the strong advantage of permeability.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Wherein, the described cutter for metal laser cutting machine is formed by Lanthanum Chromite calcium pottery, sodium-potassium eutectic and rubber composition, described Lanthanum Chromite calcium pottery comprises chromic oxide, lanthanum trioxide and calcium oxide, described Lanthanum Chromite calcium pottery occupies the 47%-54% of the overall component of cutter of metal laser cutting machine, described sodium-potassium eutectic occupies the 41%-44% of the overall component of cutter of metal laser cutting machine, and described silicon rubber occupies the 3%-11% of the overall component of cutter of metal laser cutting machine.
Further illustrate, described silicon rubber comprises Polymethyl methacrylate, described Lanthanum Chromite calcium pottery occupies 51% of the overall component of cutter of metal laser cutting machine, described sodium-potassium eutectic occupies 42% of the overall component of cutter of metal laser cutting machine, and described silicon rubber occupies 7% of the overall component of cutter of metal laser cutting machine.
Further illustrating, chromic lanthanum ceramics principal crystalline phase is the stupalith of Lanthanum Chromite (LaCrO3).There is isometric system perovskite structure.Density 6.5g/cm3.Fusing point 2490 DEG C.Resistivity 1 Ω cm when 100 DEG C.Heatable to material direct-electrifying, its surface temperature can reach ~ and 2000 DEG C, in black or deeply blackish green.When the mean coefficient of linear thermal expansion of room temperature to 1000 DEG C is 9.7 × 10-6/ DEG C of room temperature, thermal conductivity is about 0.018J/ (cms DEG C).Main raw material is three oxidation three lanthanum and chromic oxide.Adopt general electronic ceramic process to can be made into clavate heating element, form through high temperature sintering.The heating element emissivity made of its and thermo-efficiency all high, can work in atmosphere 1400 DEG C, as temperature continues to raise then, chromium volatilization is serious, thus uses and is restricted.Interpolation strontium oxide, barium oxide can limit the performance of chromium to a certain extent, improve the stability under high temperature oxidative atmosphere.
Further illustrating, sodium-potassium eutectic is liquid, is not generally common in order to strengthen the alloy that metal hardness combines.Can use as siccative, oxygen scavenger, reductive agent, but because cost costly, is of little use except special requirement.Siccative conventional during Na-K alloy is organic as metal, deoxygenation reagent, reductive agent etc. have very large advantage in metal is organic, have many uses.Now its preparation method and application notice are issued everybody to share.The invention provides a kind of cutter for metal laser cutting machine, there is high-and low-temperature resistance performance and the strong advantage of permeability.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
