Abstract
A turning cutter is provided and is comprised of a cutter body, whose ends are clapboard-shaped. A fixed socket is arranged above the cutter body. The lateral face of the clapboard-shaped ends raises and extents to form an arch head. A spacer is arranged on the socket at the ends of the cutter body and has a shape matched with the clapboard-shaped ends. A blade is arranged on the spacer and has a cylindrical shape. A pressure board is fixed on the cutter body through a fixed bolt; and one end of the pressure board presses and is connected with the blade. The blade is comprised of a cutting edge and a base; wherein, the cutting edge is designed as a reversed prism, and the upper part of the cutting edge is provided with a layer of compound crystalline cubic boron nitride coating. The utility model of the cylindrical cutter blade has the exquisite design and applies the sintering technology of compound crystalline cubic boron nitride, thereby the technical requirement of constant cutting and re-cutting of steel roller with high speed can be solved effectively and smooth processing surface as well as good measurement stability can be obtained.
Description
Technical field
The utility model relates to cutting tool, and particularly the high-speed tool steel roll is waited for bus and cut the dedicated tool of usefulness.
Background technology
In the use of universal lathe and special roller lathe, the lathe tool cutting element that is absolutely necessary moves and finishes the machining of workpiece by the length feed motion and the traverse feed of lathe tool on lathe slip crate knife rest.In iron and steel enterprise's rolling system, roll must the off-line reconditioning when rolled products reaches certain kilometer length or roller surface and defective occurs according to its technological requirement as important production parts.The reconditioning mode comprises: go up the special roller lathe when 1, roll needs big cylindrical allowance because of blemish earlier and carry out cylindrical turning carry out fine finishining to meet the requirements of roll shape and geometric accuracy by roll grinder again to certain size; 2, directly finish roll shape and the precision that needs by the roll grinder grinding motion.Second kind of reconditioning mode generally is used for roll is not had roll surface defective or the very little reconditioning of roll cylindrical allowance.
In view of the high-speed tool steel roll puts into production use, first kind of reconditioning mode do not reach continuous cutting requirement and forms blank spot on the turning process because of having cutter now when it blemish (crackle, lose flesh) occurs or needs big cylindrical allowance, not only operating efficiency is low, production cost is high and directly adopt second kind of reconditioning mode, and influences produced on-site because of the roll turn around time significantly prolongs.
Summary of the invention
The purpose of this utility model is to provide a kind of turning cutting tool, adopt the unique design of polycrystalline cubic boron nitride sintering technology and column type blade, high-speed steel roll cutting and heavy cut technological requirement continuously be can effectively solve, brighter and cleaner finished surface and good dimensional stability obtained with this.
For achieving the above object the technical solution of the utility model:
Turning cutting tool comprises, cutter hub, and its end is the wedge structure, has fixed groove on it, and the lateral projections of this wedge end extends to form an arc-shaped head; Pad is arranged at the fixed groove of cutter hub end, and shape and wedge end are complementary; Blade is arranged on the pad, and is cylindrical; Pressing plate is fixed on the cutter hub by set bolt, one end crimping blade.
Again, described blade comprises cutting edge and base portion, and this cutting edge is negative chamfered edge design; The chamfer angle of blade cutting edge is-5 °～-10 °; Described blade cutting edge top is the polycrystalline cubic boron nitride coating.
The structural design of above-mentioned blade can effectively strengthen blade, significantly improve edge surface quality and tool life; Cutter its cutting plane when machining is an arc surface, can make the blade cut land cut and cut out workpiece gradually, can disperse radial-thrust force and feed drag largely, make to impact to obtain relaxing and the raising stable cutting, in the protection blade, avoided the strain of process system and the influence that cutting vibration brings; 360 ° of peripheries on blade top are the cutting land, the cutting of transposition at once when the passivation of a certain cutting face, thus make the stock-removing efficiency of blade reach maximization; Can make workpiece to be machined reach higher surface quality and good dimensional stability;
Described pressing plate comprises fixed part, extends to form connecting portion, extends to form pressure contact portion from the connecting portion bending from fixed part.
Blade top material is a polycrystalline cubic boron nitride, and its characteristic is: (1) has higher hardness and wearability.Its micro-shadow degree is HV8000-9000, and the hardness of its sintered body PCBN is HV3000-5000; (2) has very high heat endurance.Its hear resistance can reach 1400-1500 ℃, and the hardness in the time of 800 ℃ also is higher than the normal temperature hardness of pottery and carbide alloy; (3) has excellent chemical stability.In atmosphere and steam, in no any variation below 900 ℃ and stable, even in the time of 1300 ℃ and also almost not reaction such as Fe, Ni, Co, more can rapid wearing and tearing as diamond, at this moment it still can keep the hardness of carbide alloy; (4) has thermal conductivity preferably.In all kinds of cutter materials, its thermal conductivity is only second to diamond, and along with its thermal conductivity factor of rising of temperature increases progressively; (5) has coefficient of friction preferably.And the coefficient of friction between different materials is 0.1-0.3, and with the raising of cutting speed, its coefficient of friction reduces.
So, when utilizing this dedicated tool that high-speed steel roll is carried out turning, can remove roller surface defect (crackle, lose flesh etc.) well, satisfy roll continuously cutting and heavy cut technological requirement and reach the smooth finish surface quality and the excellent dimensions precision in, thoroughly solved the blank on the high-speed steel roll turning process.
The beneficial effects of the utility model
1, lathe tool increases substantially at the cutting power of high-speed steel.
The hard alloy cutter per car is cut a barrel length (1780mm) and is needed sharpening cutter and tool setting 3.5 times (15 minutes/time), the sintex per car is cut a barrel length (1780mm) need carry out cutter transposition and tool setting 6 times (needing 18 minutes), and cube boron nitride cutter can once be finished the turning of barrel length, so its stock-removing efficiency significantly improves.
2, the roll precision size after the lathe tool turning significantly improves
The high-speed steel roll of carbide-tipped lathe tool processing, very fast in view of the rate of depreciation of its cutting edge, and the turned phenomenon of the edge of a knife often takes place, so the surface smoothness of processing back roll only is 3- 4, roll cylindricity≤0.25mm, and require relatively harsher to operative employee's technical ability; Sintex is relatively large in fine finishining turning role, but the bigger influence of the frequent tool setting in regular tipping and the turning process its machining accuracy, so the surface smoothness of processing back roll only is 4- 5, roll cylindricity≤0.20mm; And through lathe tool turning except the performance deficiency of effectively avoiding above-mentioned cutter, the roller surface fineness after the processing reaches 5- 7, roll cylindricity≤0.05mm has thoroughly satisfied the processing request of high-speed steel roll.
