Abstract
The invention discloses a high-intensity industrial cutter for steel rolling, and relates to the technical field of cutters. The high-intensity industrial cutter consists of 15-20 percent of carbonized titanium, 10-40 percent of stainless steel powder, 0.1-5 percent of carbonized tantalum, 0.1-5 percent of carbonized niobium, 10-40 percent of carbonized tungsten, 5-10 percent of carbon powder and 10-20 percent of a hard alloy forming agent. The cutter is high in hardness and good in abrasion resistance and has obviously advantages of heat stability, heat conduction property, corrosion resistance, oxidization resistance, high temperature hardness and high temperature strength; the cutter can continuously and quickly cut steel at high temperature, during the cutting, the friction is small, the cutter is sharp, an incision is tidy and is free of burrs, and for cutting processing production, the cutting speed can be greatly increased, so that the production efficiency is improved; and materials which are difficult to cut can be machined by the cutter, the materials can be accurately machined, a product is high in precision, and as the manufacturing materials are safe and environmentally-friendly, people feel safe and released when cutting foods and medicines with the cutter, and environment friendliness is facilitated.
Description
Technical field
The present invention relates to cutting-tool engineering field, be specifically related to a kind of steel rolling high strength industrial cutter and preparation technology thereof.
Background technology
Along with improving constantly of human living standard, the demand of resource is also constantly increased, and the operating cost of resource and further difficulty rock stratum in open up brought new problem, bring and the opposing of cutter broken and the intensity of repeated stress failure, the requirement that each side such as toughness and wear resistance is more and more higher, thus, to having high rigidity, there are again the high-abrasive material of high strength and new parts, new cutter, the cutter adapted under extreme condition is had higher requirement, traditional Wimet due to intensity and hardness high, wear resistance is good, red hardness is good, thermal expansivity is little, a series of premium properties such as the high and chemical stability of Young's modulus is good, it is widely used on various cutter.
Machining be in mechanical workout the most substantially, the most reliable processing means, and the performance of cutter is one of deciding factor affecting machining efficiency, precision, surface quality etc.Cutter material experienced by several developmental stage such as carbon tool steel, rapid steel, Wimet, pottery and superhard material.According to the data of CIRP, due to the improvement of cutter material, add the cutting speed allowed man-hour and almost namely improved 1 times every 10 years.In the modern course of processing, the most effectual way improving working (machining) efficiency remains employing High Speed Cutting Technique.Conventional tool cannot be competent at the machining of various high-strength, the high hard and high speed engineering materials required for modern development in science and technology because of its limitation, sintex, then with the thermotolerance of its excellence, wear resistance and chemical stability, shows the incomparable advantage of conventional tool in high speed cutting field and cutting difficult-to-machine material.
On domestic market, sintex mainly contains two large classes: alumina base and silicon nitride base ceramic cutting tool.Compared with other cutter material, the most significant shortcoming of sintex is exactly fracture toughness property deficiency, bending strength and thermal shock resistance poor, when cutting temperature shows change, easily crack.As one of the important indicator evaluating its resisting breakage ability, sintex needs to improve its hardness, bending strength and fracture toughness property by suitable means, and carry out milling, plane, boring and other intermittently add man-hour, the fracture toughness property of blade material is even more important.
Summary of the invention
It is good that technical problem to be solved by this invention is to provide a kind of intensity, the steel rolling high strength industrial cutter that preparation method is simple.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of steel rolling high strength industrial cutter, is made up of the component of following weight percent,
The comminuted steel shot that described Stainless Steel Powder adopts 06Cr19Ni10 steel to make, i.e. 304 Stainless Steel Powders.
Described Wimet forming agent adopts Wimet forming agent SDB.
A kind of steel rolling high strength industrial cutter preparation technology:
1) take raw material by the weight proportion of raw material each in component, raw material is mixed to make blank stand-by;
2) in blank, add alcohol, blank and alcohol add in 1:2 ratio, and grinding machine for grinding 5 hours, make compound after thoroughly being mixed by blank with alcohol;
3) compound is put into container precipitation 2 hours, the alcohol clarified above is carried;
4) compound in step 3) is put into drying cupboard drying, the residual alcohol in compound is vapored away, make compound powdering material;
5) add forming agent after powder-material being crossed 120 mesh sieves to mix, make moulding material;
6) moulding material is put into mould compression moulding, and model surface add low cobalt powder as release coating after put into vacuum pressed sintering oven, vacuumize in stove, heat 1.5 hours, be heated to 600 DEG C, Wimet forming agent burning extract out;
7) rear insulation 20 minutes has been heated, heat to 1200 DEG C again, time controling, at 1.5-2 hour, enters solid item formative stage, Gu the shaping rear insulation of item 15 minutes, heat to 1450 DEG C again, time controling, at 1 hour, enters liquid item densification stage, and automatically lower the temperature after being incubated 20 minutes again after the densification of liquid item completes (needing 14 hours) is to less than 100 DEG C, product is taken out in blow-on, utilizes grinding machine precision sizing to become product.
The mass content of described low cobalt powder is below 15%.
The invention has the beneficial effects as follows: manufacture craft of the present invention is simple and easy to realize, and its production efficiency is high, good article rate is high, be conducive to mass mechanized production, the cutter of preparation, its hardness is high, wear resistance good, and its thermostability, thermal conductivity, solidity to corrosion, oxidation-resistance and hot hardness, hot strength etc. all have a clear superiority in; It can at high temperature cut continuously fast, and during cutting, frictional force is little, cut sharper, otch is more neat, impulse-free robustness, for machining production, greatly can improve cutting speed, and then enhance productivity; It can not only process the various material being difficult to cut, and processing is accurate, Product Precision is high, and makes material safety and environmental protection due to it, cuts safer relieved, be conducive to environmental protection for food and medicine.
