Description
Technical field
The present invention relates to superhard material field, be specially the middle intermediary and using method thereof that firmly connect carbide chip and cutter hub.
Background technology
Carbide alloy is a kind of alloy material be made up by powder metallurgical technique of the hard compounds of refractory metal and binding metal.Carbide alloy has that hardness is high, wear-resisting, intensity and a series of premium properties such as toughness is better, heat-resisting, corrosion-resistant, and particularly its high rigidity and wearability, even if also substantially remain unchanged at the temperature of 500 DEG C, still have very high hardness 1000 DEG C time.Carbide alloy is widely used as cutter material, as lathe tool, milling cutter, planing tool, drill bit, boring cutter etc., for cutting cast iron, non-ferrous metal, plastics, chemical fibre, graphite, glass, stone material and common iron, also can be used for cutting the difficult to machine materials such as heat resisting steel, stainless steel, potassium steel, tool steel.
Carbide alloy has very high hardness, intensity, wearability and corrosion resistance, be described as " industrial tooth ", for the manufacture of cutting element, cutter, cobalt tool and wear-resisting spare part, be widely used in the fields such as military project, space flight and aviation, machining, metallurgy, oil drilling, mine instrument, telecommunications, building, with the development of downstream industry, the carbide alloy market demand continues to increase.And following new-and high-tech weaponry and equipment manufacture, the progress of most advanced branches of science technology and the fast development of nuclear power source, by the demand of hart metal product improved energetically high technology content and high-quality stability.
Carbide alloy is most popular class High-speed machining (HSM) cutter material, and this type of material is produced by powder metallurgical technique, is made up of hard carbide (being generally tungsten carbide wc) particle and the softer metallic bond of quality.At present, have the WC base cemented carbide of hundreds of heterogeneity, in them, major part all adopts cobalt (Co) as bonding agent, and nickel (Ni) and chromium (Cr) are also conventional bonding agent elements, in addition also
Some other alloying element can be added.
High-efficient cutting is the advanced machining technology moving towards rapidly practical application the nineties in 20th century, and at Aero-Space, precision die, auto parts and components, and the industry such as precision optical machinery is widely used.Statistics shows, in metal cutting field, (1) cutter price reduces by 30%, and the cost per unit of final products reduces by 1%; (2) cutter life improves 50%, and cost per unit reduces by 1%; (3) stock-removing efficiency improves 20%, and cost per unit can reduce by 20%.Can find out, high-efficient cutting by improving working (machining) efficiency, can reach the object reducing each side expenditures such as corresponding cost of labor, energy resource consumption, equipment depreciation within the product life cycle, thus greatly reducing product cost.Moreover, efficient production efficiency can help enterprise to catch the market opportunity, thus the synthesized competitiveness of enterprise.
Hard alloy cutter physical property is balanced, is ideal cutter material.In fact, carbide alloy is in the past in time of 90 years, improving cutting speed and stock-removing efficiency aspect plays important role always.Along with further developing of Cutting-Tool Coating Technology, the cutting ability of carbide alloy there occurs the change of essence, and the range of application in high-efficient cutting processing constantly expands.As cutter material, carbide alloy is most important part in current High-speed Machining Technology, in cutting practice, play indispensable effect.
Carbide alloy has original advantage having concurrently in hardness and toughness.Tungsten carbide (WC) itself has very high hardness (exceeding corundum or aluminium oxide), and its hardness also seldom declines when operating temperature raises.But it lacks enough toughness, and this to be absolutely necessary performance for cutting tool.In order to utilize the high rigidity of tungsten carbide, and improve its toughness, people utilize metallic bond to be combined by tungsten carbide, thus make this material both have hardness considerably beyond high-speed steel, can bear again the cutting force in most of machining simultaneously.In addition, it can also bear the cutting high temperature that High-speed machining produces.
Hard alloy workpiece can adopt kinds of processes method shaping.According to the size of workpiece, complex-shaped level and production lot, most of cutting tip is all adopt top pressure and the compression molding of base pressure formula rigid die.When suppressing each time, in order to the uniformity of holding workpiece weight and size, must ensure that the powder amount (quality and volume) flowing into die cavity is all identical.The mobility of powder controls mainly through the Size Distribution of agglomerate and the characteristic of organic bond.By applying 10-80ksi(Kilopounds Per Square Foot on the powder loading die cavity) briquetting pressure, just can form mold pressing workpiece (or title " blank ").Blank is processed, just can obtain the sintered-carbide tool that can extensively affect, as hard alloy cutter etc.
Hard alloy cutter is higher than high-speed steel cutting speed 4 ~ 7 times, and cutter life is high 5 ~ 80 times.Mfg. moulding die, measurer, the life-span is higher than alloy tool steel 20 ~ 150 times.The hard material of machinable about 50HRC, but carbide alloy fragility is large, can not carry out machining, be difficult to make complex-shaped solid tool, thus often make difform blade, adopt the methods such as welding, bonding, mechanical grip to be arranged on cutter hub or mold and use.
Present stage major part hard alloy cutter be all adopt welding, carbide chip is installed on cutter hub by the method such as bonding, but the hard alloy cutter that this mode is supported in use, frequent appearance is because carbide chip and cutter hub are in conjunction with bad, and then occur that fracture and crackle occur, have impact on range of application and the service life of hard alloy cutter.
