Abstract
The utility model relates to a kind of overall boron nitride cutter grooving turning cutting tool, and be specifically related to a kind of overall cubic boron nitride blade for high strength chip breaking, it comprises blade body, and blade body is triangular prism, and three incline places of triangular prism are processed with cutting edge.Relative to prior art, the utility model utilizes three inclines of grooving cutter, form 3 cutting edges, reasonable in design, stock utilization is high, adopts polycrystalline cubic boron nitride material, due to the self character of boron nitride material, blade can bear very large impulsive force, and cutter has good impact resistance, improves life-span and the production efficiency of blade.
Description
Technical field
The utility model relates to a kind of overall boron nitride cutter grooving turning cutting tool, is specifically related to a kind of high economy and the overall boron nitride cutter grooving turning cutting tool of applicable high strength chip breaking processing.
Background technology
At present in machining grooving field, select to be applicable to processing according to material behavior and the excellent processing solution of economic performance, usually have carbide alloy grooving cutter, coated carbides grooving cutter, ceramic grooving cutter, welding boron nitride grooving cutter.If Continuous maching generally can be processed to fix a cutting tool, if but run into high strength and intermittently process, and when material hardness is very high, the object that just cannot reach expection of above cutter performance.Main manifestations has 2 points: 1, economy is not high.2, the life-span of cutter is low.
Utility model content
The technical problems to be solved in the utility model is: the grooving cutter used at present is intermittently adding man-hour for high strength, and the economy life-span that is not high and cutter is low, for solving the problem, provides a kind of overall cubic boron nitride blade for high strength chip breaking.
The purpose of this utility model realizes in the following manner:
For an overall cubic boron nitride blade for high strength chip breaking, it comprises blade body, and blade body is triangular prism, and three incline places of triangular prism are processed with cutting edge.
The cutting edge of blade body is processed with the primary clearance of 0 ° ~ 14 °, and cutting edge both sides are processed with the front clearance of 3 ° ~ 7 °.
Described cutting edge place is processed with the chamfered edge of 0 ~ 0.3mm width, and chamfered edge angle is 0 ° ~ 25 °.
Described blade body is regular triangular prism, and the thickness of blade body is 4 ~ 10mm.
Relative to prior art, the utility model utilizes three inclines of grooving cutter, form 3 cutting edges, reasonable in design, stock utilization is high, adopts polycrystalline cubic boron nitride material, due to the self character of boron nitride material, blade can bear very large impulsive force, and cutter has good impact resistance, improves life-span and the production efficiency of blade.

Wherein, 1 is knife bar; 2 is housing screws; 3 is blade body; 4 is pressing plates; 5 is bridge screws; 6 is cutting edges; 7 is main rear knife faces; 8 is minor flanks.
Detailed description of the invention
As shown in accompanying drawing 1-Fig. 2, a kind of overall cubic boron nitride blade for high strength chip breaking, it comprises blade body 3, and blade body 3 is triangular prism, and three incline places of triangular prism are processed with cutting edge 6.The cutting edge 6 of blade body 3 is processed with the primary clearance of 0 ° ~ 14 °, and blade body 3 is formed main rear knife face 7, and cutting edge 6 both sides are processed with the front clearance of 3 ° ~ 7 °, and blade body 3 is formed minor flank 8.Described cutting edge 6 place is processed with the chamfered edge of 0 ~ 0.3mm width, and chamfered edge angle is 0 ° ~ 25 °, as 0 °, 2 °, 5 °, 8 °, 10 °, 12 °, 15 °, 18 °, 20 °, 23 ° or 25 °.Described blade body 3 is regular triangular prism, and the thickness of blade body 3 is 4 ~ 10mm, as 4mm, 4.76mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm.
Blade is arranged on the installation process on knife bar: the cutter nest place first blade body 3 being placed on knife bar 1, then blade body 3 is pushed down with pressing plate 4, then push down pressing plate 4 with bridge screw 5, blade body is pressed on the cutter nest place of knife bar 1, finally pushes down the upper surface of blade body 3 with housing screw 2.
The beneficial effects of the utility model are: 1. use leg-of-mutton section groove blade, first the sword number of cutting edge is increased, thus add the economy of cutter use.2. due to the self character of boron nitride material, blade can bear very large impulsive force, and cutter has good impact resistance.3. abundant tread amplitude can be selected: 4-10mm.4. knife bar adopts double locking, improves the stability continuously, intermittently adding man-hour.In addition, infeed processing can also be carried out.5., by using overall cubic boron nitride section groove blade, the long-life of cutter can be realized in interrupted processing.6. cutter can carry out the design processing of positive rake angle, can reduce cutting resistance when cutting like this.Thus machining is become more brisk.7. the Tool Design of uniqueness, can solve the chip problem adding man-hour.
