Description
Technical field
What the present invention relates to is the cutter in a kind of metal cutting technology field, specifically be a kind of based on polycrystalline cubic boron nitride can the peeling special use titanium alloy bar turning tool.
Background technology
Since the 1950's, owing to pressing for of aeronautical and space technology, casting titanium industrial requirement also just arises at the historic moment.Along with industrial expansion, the demand of some large titanium alloy bars is increased suddenly, the crudy to its blank is also more and more higher simultaneously.At present, hard alloy cutter is adopted in the titanium alloy bar peeling usually, but hard alloy cutter is serious because of blank Facing material inequality, oxide skin, and reason such as bar linearity difference, cause in the working angles cutting-in excursion big, cutting force fluctuation is big, cutting vibration is serious, causes the cutter tipping and is embedded on the surface of workpiece, thereby introduced the titanium alloy tungsten contamination.And the introducing of tungsten inclusion makes titanium alloy bar exist many hard defectives, thereby greatly reduces the performance of titanium alloy, even causes waste product.In addition, titanium alloy is in process, and deformation coefficient is little, the cutting temperature height, and chill phenomenon is serious, makes its processing become very difficult, and working (machining) efficiency is low, and cutter consumption is big, is difficult to satisfy the needs of industrial development.
Prior art adopts two lathe tools to carry out external cutting simultaneously mostly and can enhance productivity significantly.Promptly on former tool post, be spaced a distance another lathe tool is installed again, the parallel side by side installation of two lathe tools, two lathe tool cutter head spacings are less than half of total processing length; If allowance is bigger, and need carry out the light piece surface time, then these two lathe tools will carry out ladder and install.Two lathe tools by bite direction difference in height are being the allowance of first cutter when going surplus.During installation, carry out the tool setting of second lathe tool earlier, then saddle or upper slide rest are released, the just forward lathe tool of the first is installed again, just carry out turning with middle carriage feed to total processing dimension then.
Though can enhance productivity effectively, also far can not satisfy the requirement of titanium alloy bar processing though utilize two lathe tools that turning is installed side by side.At first, two lathe tools are installed processing side by side just in the improvement of technology aspect, machining tool are not carried out the improvement of essence, and installation procedure complexity, tool setting difficulty.Because will guarantee simultaneously just can guarantee turning accuracy at the spacing dimension of direction of feed and cutting-in direction between the two lathe tool cutter heads, this operant level and qualification to the workman all proposes very high requirement.Secondly,, refer more particularly to this most key technical barrier of tungsten contamination in the titanium alloy bar peeling process, still do not form an effective special-purpose topping machanism for this heavily loaded turning processing of titanium alloy bar peeling.In a word, the process technology of present titanium alloy bar has not satisfied the needs of industrial development far away.
Summary of the invention
The present invention is directed to the prior art above shortcomings, a kind of titanium alloy bar turning tool is provided, the cooperatively interact special-purpose lathe tool of titanium alloy peeling of a kind of double-pole head of participating in cutting of its circular shear blade and square blade efficiently solves the low problem of titanium alloy tungsten contamination and working (machining) efficiency.
The present invention is achieved by the following technical solutions, the present invention includes: double blade assembly, edge bearing and the knife bar of double-pole groove cutter head, clamp assembly, special cutting edge, wherein: circular knife groove and square cutter groove are opened on cutter head abreast, thereby have guaranteed the installation of circular shear blade and square blade.This double-pole groove cutter head is fixedlyed connected with knife bar, and clamp assembly and edge bearing are fixedly set in the cutter head respectively and the both sides that are positioned at the double blade assembly closely contact.
Described double blade assembly comprises: special cutting edge circular shear blade and the square blade made by polycrystalline cubic boron nitride, wherein: circular shear blade is a column structure, 0 ° of its anterior angle, 11 ° of relief angles, cutting edge inclination are-20 °, blade cut sword length 12mm, thickness 6.8mm, the blunt circle of cutting edge is handled the also negative chamfered edge of band, chamfered edge width 0.8mm, chamfered edge anterior angle-20 °; Square blade is a cuboid shape structure, 0 ° of its anterior angle, 11 ° of relief angles, 30 ° of tool cutting edge angles, cutting edge inclination-20 °, blade cut sword length 12mm, thickness 6.8mm, corner radius 2.0mm, the blunt circle of cutting edge is handled the also negative chamfered edge of band, chamfered edge width 0.8mm, chamfered edge anterior angle-20 °.
Described cutter head is provided with circular and square cutter groove, and described double blade assembly is movably set in the cutter groove.
Beneficial effect of the present invention is: the high-performance advantage of giving full play to polycrystalline cubic boron nitride, and the effective processing by the blade cutting edge, make the polycrystalline cubic boron nitride blade obtain higher shock resistance, thereby can finish the peeling work of titanium ingot efficiently, and then thoroughly solve this technical barrier of titanium alloy tungsten contamination; Adopt the design of double-pole head clamping to make two blades work in coordination, have complementary advantages, obtain very high material removing rate under the prerequisite that improves cutter life and assurance crudy, working (machining) efficiency will promote significantly.Double blade lathe tool that we can say this circular shear blade combination square blade is suitable for titanium alloy bar peeling operation most, not only production efficiency height, and titanium material yield rate height, and the cutter consumption is few.
