Abstract
The invention relates to a preparation method of a super sharp alloy-steel cutter and the implementation of the invention comprises the following preparation steps: 1. material selection: selecting chrome alloy steel, weight ratios of which has the following chemical compositions: C accounts for 0.35 to 0.45 percent, Si accounts for 1.00 percent, Mn accounts for 1.00 to 0.80 percent, P accounts for 0.35 percent, S accounts for 0.03 percent, Cr accounts for 12.00 to 14.00 percent, Mo accounts for 0 to 1.00 percent and the rest are Fe and impurities and the alloy steel is adopted as welding material of cutter edge of the cutter; 2. molding: making the welding parts of the material of the cutter edge of the cutter into section series with thickness of 0.6 to 6.0mm and cutting the section series into welding materials with different widths and lengths; 3. welding: welding steel welding materials of the corresponding chromium alloy cutter on the welding parts of the cutter by argon arc and using steel welding bars of the corresponding chromium alloy cutter; 4. heat treatment: heating the welded cutter by an air pressure gun to more or less 1100 DEG C and cooling the welded cutter by natural air to 650 to 300 DEG C to preserve heat; 5. buffing and polishing: after the cutter carries out heat treatment, buffing and polishing the cutter into a smooth, sharp and permanently stainless cutter. The preparation method of the invention needs no forging, thus saving energy, materials and time.
Description
Technical field
The present invention relates to a kind of preparation method of cutter, especially a kind of preparation method of ultra-sharp steel alloy cutting tool.
Background technology
Prior art product cutter preparation method, the one, use with a kind of shaped steel and be made into cutter by forging processing steps such as sanding and polishing, as all steel cutter, cutting edge, cutter hub are a kind of material, the cost height, and another kind of is that the cutter hub blade is made cutter with different steel by forge hot connection and heat treatment step, these two kinds of methods all be unable to do without heats forged, its shortcoming is that technology is complicated, and it is more to consume energy, and cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of preparation method that does not need the ultra-sharp steel alloy cutting tool of forge hot, its technology is simple, lower, energy-conservation, the material-saving of production cost.
The technical scheme that solves the technology of the present invention problem is: select the evanohm shear steel that contains following chemical compositions by percentage for use: C 0.35～0.45%, Si 1.00%, Mn1.0～0.8%, and P 0.35%, S0.03%, Cr 12～14%, and Mo 0～1.00%, and all the other are Fe and steel-making impurity, comprising 1Cr13,2Cr13,3Cr13, the evanohm shear steel of 3Cr13Mo and five models of 4Cr13; Above-mentioned cutter steel are made thickness 0.6～6.0mm, and section bar series solder and welding rod that length and width cuts as required are welded in the scolder argon arc on the cutter weldment with the chromium alloyed steel welding rod; Heat treatment then makes it to reach about 1100 ℃ with air pressure gun heating weldment edge of a knife scolder, and natural air cooled to 650 ℃ to 300 ℃ insulations, sanding and polishing is the finished product cutter.
Good effect of the present invention is: uses chromium alloyed steel in a small amount to make the cutting edge material of cutter,, can save a large amount of steel alloys, and cutting edge roundness is smooth by a large amount of cutters of step manufacturing such as welding, polishing, polishings, and Never-rusty, its sharpness spy is good.
The specific embodiment
Below by embodiment the present invention is further described.
Enforcement of the present invention comprises that selection, moulding, welding, heat treatment, polishing, glossing step finish the making ultra-sharp steel alloy cutting tool.Its making step comprises: 1, selection, choose the chromium alloyed steel that contains following chemical analysis percentage by weight, and C 0.35～0.45%, and Si 1.00%, Mn 1.00～0.80%, and P 0.35%, and S 0.03%, Cr 12.00%～14.00%, and Mo 0～1.00%, and all the other are Fe and impurity.Make the edge of a knife wlding of cutter with this steel alloy; 2, moulding is made the section bar series that thickness is 0.6～6.0mm with above-mentioned cutter edge of a knife material weldment, cuts into the wlding of different in width and length; 3, welding is welded in corresponding evanohm shear steel wlding on the cutter weldment by argon arc welding, uses corresponding evanohm shear steel welding rod this moment; 4, heat treatment is heated to the cutter after the welding about 1100 ℃ with air pressure gun, and is natural air cooled to 650 ℃～300 ℃ insulations; 5, grinding and buffing will become cutter smooth, sharp, Never-rusty through heat treated cutter sanding and polishing.Owing to need not forge energy-conservation, material-saving, save time.
Claims (1)
1, a kind of preparation method of ultra-sharp steel alloy cutting tool, 1), selection be characterised in that its making step comprises:, choose the chromium alloyed steel that contains following chemical analysis percentage by weight, C 0.35%～0.45%, Si 1.00%, Mn1.00%～0.80%, P 0.35%, and S 0.03%, Cr 12.00～14.00%, Mo 0～1.00%, and all the other are Fe and impurity, makes the edge of a knife wlding of cutter with this steel alloy; 2), moulding, it is 0.6～6.0 millimeter section bar series that above-mentioned cutter edge of a knife material weldment is made thickness, cuts into the wlding of different in width and length; 3), welding, corresponding evanohm shear steel wlding is connected on the cutter weldment by argon arc welding, use corresponding evanohm shear steel welding rod this moment; 4), heat treatment, with the welding after cutter be heated to about 1100 ℃ with air pressure gun, natural air cooled to 650 ℃～300 ℃ insulations; 5), grinding and buffing, will become commodity cutter product through heat treated cutter sanding and polishing.
