Abstract
The invention relates to a nanometer iron powder used in ultra-rigid alloy blade, wherein it comprises cutting the irregular sheet particles of iron powder at low, middle and high frequencies, into first, second and third powders, then mixing them at 2:6:2.
Description
Technical field
The present invention relates to a kind of nano grade iron powder, be specially a kind of iron powder dedicated for production of ultrahard alloy cutter head.
Background technology
Number of patent application is 2006100481685 to disclose a kind of cutting production technology of metal nanometer powder zero boundry particle, a kind of brand-new zero boundry particle cutting metal nano-powder material technology has been put down in writing in this patent application, with the iron powder is example, step comprises, iron powder is placed under-5 ℃～+ 20 ℃ the zero boundary processing temperature state, then ferrous powder granules is carried out high-speed cutting, per minute is controlled at 4000～6000 times (preferred 6000 times/minute), high frequency to the ferrous powder granules 4000～6000 rev/mins (preferred 4000 rev/mins) after the cutting grinds then, carry out the physics reduction again, surface treatment can obtain product, last classification and sorting.Utilize the high frequency cutting implement can process the iron powder of different Nano grades, utilize the iron powder of the specific particle diameter that this method produces to have the different excellent specific property of material that conventional art is produced, the nanometer iron powder characteristic of each different stage that this explained hereafter goes out has tangible difference, through being widely used in different industries or field after sizing screening and the proportioning.
Produce in the technology of production of ultrahard alloy cutter head, iron powder mainly has been the wear-resisting effect of cutter head.Because homemade iron powder is irregular sheet-like particle, and particle average out to 82 μ m---the crude iron powder of 46 μ m.The deposit of irregular sheet-like particle iron alloy powder is being subjected under the intense impact situation fracture extremely easily, simultaneously with the mutual high-speed friction of high rigidity material under wear rate very big, the wear-resisting relatively time is very short, cutting speed is slow, the integrated cost height, and the international market price is low.
Summary of the invention
The present invention is not good and cause its abrasion resistance not enough in order to solve the iron powder quality of using in the production production of ultrahard alloy cutter head that exists in the prior art, clipping time is short, the problem that cutter head ruptures easily, unit cost is high and a kind of iron powder dedicated for production of ultrahard alloy cutter head is provided.
The present invention is realized by following technical scheme, and a kind of iron powder dedicated for production of ultrahard alloy cutter head is to be made by following method:
Be controlled in frequency 1600 times/minute-2000 times/minute and temperature under 2 ℃-18 ℃ the situation, the irregular sheet-like particle of raw material iron powder of 82 μ m is cut into the irregular slightly spherical particle material of D50=61 μ m, as No. 1 powder, be controlled in intermediate frequency 2600 times/minute-3200 times/minute and temperature under-3 ℃-9 ℃ the situation, the irregular sheet-shaped material ferrous powder granules of 82 μ m is cut into D50=35 μ m spherical particle material, as No. 2 powder, be controlled in high-frequency 4000 times/minute-6000 times/minute and temperature under-2 ℃-15 ℃ the situation, the irregular sheet-shaped material ferrous powder granules of 82 μ m is cut into D50=8 μ m spherical particle material as No. 3 powder, with 1,2, No. 3 iron powders are uniformly mixed to form iron powder dedicated for production of ultrahard alloy cutter head in 2: 6: 2 ratio.
At this preferred version on the basis of such scheme for being controlled in frequency 1800 times/minute and temperature under 7 ℃-13 ℃ the situation, the irregular sheet-like particle of raw material iron powder of 82 μ m is cut into the irregular slightly spherical particle material of D50=61 μ m, as No. 1 powder, be controlled in intermediate frequency 2800 times/minute and temperature under 0 ℃-5 ℃ the situation, the irregular sheet-shaped material ferrous powder granules of 82 μ m is cut into D50=35 μ m spherical particle material, as No. 2 powder, be controlled in high-frequency 5000 times/minute and temperature under 1 ℃-8 ℃ the situation, the irregular sheet-shaped material ferrous powder granules of 82 μ m is cut into D50=8 μ m spherical particle material as No. 3 powder.1,2, No. 3 iron powder is uniformly mixed to form iron powder dedicated for production of ultrahard alloy cutter head in 2: 6: 2 ratio.
The present invention utilizes the technology of putting down in writing in the patent application of " cutting production technology of metal nanometer powder zero boundry particle ", and 1,2, No. 3 iron powder is uniformly mixed to form iron powder dedicated for production of ultrahard alloy cutter head in 2: 6: 2 ratio.Behind the shaping cutter head, observation by 800,000 times of Electronic Speculum, special-purpose powdered iron has preferably wettability, caking property, formability, sinterability, extraordinary mechanical property is arranged, as mechanical strength, hardness, cracking resistance, bending strength and abrasion resistance other metal powder materials.Significantly improve the service life of cutter head, can also reduce copper powder consumption 2% simultaneously, reduced cobalt powder 2.2%, improve 5.1 times service life, the monolithic cost reduces by 32.06%, and abrasion resistance has improved 6.2 times, cutting speed has improved 65%, and the cutter head fracture rate drops to 0.5% from original 7%.By comparing with the like product of the U.S., Germany, Japan, with the cutter head that " special-purpose powdered iron " produced, leading indicator all reaches the technical indicator of external like product.Wherein abrasion resistance surpasses 0.8 percentage point in the U.S., and 0.6 percentage point in Germany surpasses 1.2 percentage points in Japan.
