Description
Technical field
The present invention relates to the composite powder metallurgy material technical field, refer in particular to a kind of composite-base diamond saw blade cutter head.
Background technology
Diamond disc is present DLC instrument goods in the fields such as maintenance of processing of stone, airport, road, building, various infrastructure industry consumption maximum.To the granite kind of determining, three big key elements of decision saw blade cutting benefit are: saw blade performance, cutting technique and board performance.Except that lamellar body quality and welding quality, the most important thing is the cutter head performance in the saw blade performance.And the cutter head performance depends mainly on obdurability, wearability and diamond quantity, quality, size and the proportioning thereof of carcass.
Also there are many problems in domestic diamond saw blade production at present, and it is lower mainly to show as cutting efficiency, and service life is shorter, and saw blade quality stability is poor, and comprehensive benefit is not high.The carcass kind of diamond saw blade is many at present, characteristics is respectively arranged with not enough.Cobalt-based, Ni-based tyre-e/or performance are stablized, and obdurability is good, but the cost height, and be rare metal, environmental pollution is arranged, the matrix wearability is poor.Iron-based matrix, obdurability is better, and cost is low, but manufacturability and stability are relatively poor relatively, and resultant effect is not ideal under the high-speed cutting condition.
Existing cutter head structure is traditional " sandwich " shape, is to be obtained by the diamond of strengthening two boundary layers.The cutter head of this structure is used in the big specification saw blade, and with running up of saw blade, its stationarity is relatively poor, and it is bigger to rock amplitude.Stressed when big, the saw blade that rigidity is relatively poor even can be crooked, thus make the swage set collimation poor, re-pack easily; And diamond also easily comes off, cracked, saw life is low; Power consumption is big.Chinese patent 98231787 " novel diamond saw blade " is arranged by retrieval, and its cutter head constitutes whole by the auxilliary working lining of the main working lining of multilayer alloy material and auxiliary inserts alternately.Be bumped into the discrete material that does not contain the diamond alloy in containing the main working lining of diamond alloy material, wash away the formation hole through sawdust at work, this is the multiple-cutting-edge cutter head that adopts the inserts method to form.The sharpness of its real work, stationarity all can not satisfy the requirement of quick production, and processing technology is cumbersome, and do not have corresponding cutter head component prescription and diamond proportioning.
Summary of the invention
The object of the invention provides a kind of not only sharp but also wear-resisting Composite Segment for Diamond Saw Blade.
The present invention seeks to realize like this:
Composite-base diamond saw blade cutter head comprises compound basic matrix formula, diamond proportioning and cutter head structure, it is characterized in that compound basic matrix formula mainly comprises (weight ratio): tin bronze 663,43～50%; Nickel, 7～15%; Cobalt Co, 5～15%; Iron Fe, 5～18%; Tungsten carbide wc, W, 10～16%; Titanium Ti, 2～8%; The diamond proportioning mainly comprises (weight ratio): total amount, 105～130g; Order is several 40/50, the diamond of intensity 〉=12Kg, 75～95g; Several 35/40, the intensity 〉=13Kg of order, 10～20g; Several 50/60, the intensity 〉=10Kg of order, 10～25g; Several 60/70, the intensity 〉=8Kg of order, 0～12g.
Above-mentioned compound basic matrix formula, diamond proportioning are preferably taked following three kinds of schemes (weight ratio):
(1) compound basic matrix formula is mainly: tin bronze 663,43～45%; WC, 14～16%; Co, 12～14%; Fe, 5～7%; Ni, 10～14%; Ti, 5～7%; The diamond proportioning is mainly: order is several 35/40, intensity 〉=14Kg, 10～12g; Order is several 40/50, intensity 〉=14Kg, 75～85g; Order is several 50/60, intensity 〉=11Kg, 22～25g; Order is several 60/70, intensity 〉=8Kg, 8～12g.This scheme is applicable to the hard granite of fly-cutting.
(2) compound basic matrix formula is mainly: tin bronze 663,47～50%; WC, W, 12～15%:Co, 5～10%; Fe, 10～15%; Ni, 7～9%; Ti, 4～7%; The diamond proportioning is mainly: order is several 35/40, intensity 〉=14Kg, 10～18g; Order is several 40/50, intensity 〉=13Kg, 75～85g; Order is several 50/60, intensity 〉=11Kg, 13～18g; Order is several 60/70, intensity 〉=8Kg, 0～10g.This scheme is applicable to medium hard granite of fly-cutting and φ 350, the small dimension saw blade of φ 400.
(3) compound basic matrix formula is mainly: tin bronze 663,44～46%; WC, W, 12～15%; Co, 8～10%; Fe, 7～11%; Ni, 12～15%; Ti, 5～8%; The diamond proportioning is mainly: order is several 35/40, intensity 〉=13Kg, 18～20g; Order is several 40/50, intensity 〉=12Kg, 75～90g; Order is several 50/60, intensity 〉=10Kg, 10～22g; Order is several 60/70, intensity 〉=8Kg, 0～10g.This scheme is applicable to the soft granite of high-speed cutting.
The structure of the cutter head of above-mentioned prescription is to add two 3-edge surgical knife heads that stalloy forms in the middle of the compound basic carcass.To φ 350, its structure of small dimension saw blade of φ 400 is traditional sandwich type.
This structure is to put into two 08F or No. 10 steel stalloys in compound basic carcass powder charging.When cutting processing, just formed the working face of three sword structures.Stalloy thickness is 0.5～0.8mm, and length is than more than the short 2mm of cutter head length, and height is a little less than the cutter head height.
The production technology of cutter head be mold base at 820～880 ℃ of sintering, be incubated 3～5 minutes; With the rising of temperature, progressively pressurize lentamente during heating, pressurizeing substantially to Wen Shiying puts in place; Naturally cool off the back mould unloading.Cutter head hardness is in HRB85～103 scopes; Cutter head density (cutter head weight/cutter head volume) 8.2～8.6g/cm
3
The invention has the advantages that compound basic tyre-e/or performance is stable, strength and toughness is good; Compound basic carcass and diamond adhesion are good, form the comet type hangover, have improved adamantine cutting power and utilization rate; Good manufacturability, simple to operate.Big specification saw blade adopts three sword type structures can make that saw blade operates steadily, amplitude is little, is difficult for re-packing, and the sheet material crudy is good.The optimization proportioning of diamond size, intensity, quantity had both made adamantine effect be not fully exerted, and reduced cost again.For general saw blade (φ 350, and φ 400, and φ 1200, and φ 1600, and φ 1800), the saw blade that cutter head of the present invention is produced, sharpness (production efficiency) has improved 40～50% than cobalt-based, iron-based; Improved 6～10% than cobalt-based service life, improved 15～20% than iron-based; And production cost is 40～50% of a cobalt-based, and is suitable with iron-based; The comprehensive benefit of sheet material production has improved 20～30%.
Prescription of the present invention, structure are provided by drawings and Examples.
