Abstract
The invention discloses a groove type blade. The blade is a hard blade. The surface of the blade is provided with a chip breaking and discharging groove. The chip breaking and discharging groove is close to a main cutting edge. When the groove type blade is used, after the main cutting edge cuts a workpiece, cuttings cut off from the surface of the workpiece will flow along the surface of the blade, in the process of flowing through the chip breaking and discharging groove, the cuttings are stopped by the walls and the edges of the chip breaking and discharging groove and rolled, and then the cuttings are broken in the rolling process, so that the cuttings are broken; meanwhile, the chip breaking and discharging groove can guide the flowing direction of the cuttings to make the cuttings avoid the machined surface of the workpiece to the greatest extent in the bending process, and then discharging of the cuttings is also guided; as a result, the chip breaking and discharging groove can guide and break the cuttings in the machining process of the cuttings, and therefore the problem that in the prior art, since the cuttings are rolled on the front portion of a super hard blade, the machining quality and machining accuracy of a cutter are lowered is avoided.
Description
Technical field
The present invention relates to a kind of grooved blade.
Background technology
At present, be provided with on the cutter of superhard cutting blade, conventionally on superhard cutting blade, be not provided for chip breaking and reduce cutting resistance, so that the brisk chip breaking of shear action, chip area and for realizing superhard cutting blade accurate assembly on knife bar, to improve the locating slot of machining accuracy, as the dimond synneusis superhard cutting blade in superhard cutting blade, polycrystalline cubic boron nitride superhard cutting blade, diamond brazing superhard cutting blade, cubic boron nitride soldering superhard cutting blade, diamond compact superhard cutting blade, cubic boron nitride composite piece superhard cutting blade and ceramic superhard cutting blade, and when adopting this superhard cutting blade, general by adjusting installation site and/or the knife bar installation site on knife rest of superhard cutting blade on knife bar, to obtain the positive rake angle at the cutting-edge place on superhard cutting blade, improve stressing conditions and the radiating condition at cutting edge place on superhard cutting blade, improve intensity and the shock-resistant ability of cutting edge.But adopting the cutter with this superhard cutting blade to carry out in the process of machining, the cut part of workpiece can be rolled up bits and be formed cutting band on the rake face of superhard cutting blade, without chip breaking, chip area in the situation that, smear metal band can flow to molded on workpiece or be wrapped on cutting edge through long accumulation, thereby on scuffing workpiece molded or make the cutting edge tipping on superhard cutting blade, the crudy of cutter and machining accuracy are declined; Without locating slot in the situation that, along with the continuous feeding of superhard cutting blade and continuing to increase of cutting depth, superhard cutting blade is subject to the reaction of workpiece and can between superhard cutting blade and knife bar, forms larger shearing force, this part shearing force can make superhard cutting blade on knife bar, occur play, also can make the crudy of cutter and machining accuracy decline.
Summary of the invention
The object of this invention is to provide a kind of grooved blade, be intended to solve that bits are rolled up in smear metal in prior art on the front blade of superhard cutting blade and problem that the tool sharpening quality that causes and machining accuracy decline.
In order to realize above object, in the present invention, the technical scheme of grooved blade is as follows:
Grooved blade, this blade has main cutting edge, and blade is superhard cutting blade, and the surface of blade is provided with for blocking and discharge the chip breaking chip area of smear metal when the machining, and chip breaking chip area is near the position of main cutting edge.
Superhard cutting blade is dimond synneusis blade, polycrystalline cubic boron nitride blade, diamond brazing blade, cubic boron nitride soldering blade, diamond compact blade, cubic boron nitride composite piece blade or ceramic tip.
Superhard cutting blade is welded type blade, and it comprises hard alloy substrate and is welded on the super-hard cutter bits on hard alloy substrate.
On hard alloy substrate, offer the mounting groove of through type or the mounting groove of half general formula in corner angle position that connect relative two sides, the identical complementary correspondence of super-hard cutter bits is assemblied in mounting groove.
Mounting groove is half general formula, and mounting groove is arranged symmetrically in the opposing both sides in blade.
The rake face that is blade in chip breaking chip area near a side wall surface of main cutting edge on the surface of blade, this rake face forms positive rake angle at main cutting edge place.
Chip breaking chip area is rake face place wall and the enlarging groove of opposite side wall from bottom land to the opposing inclination of notch.
On the surface of blade, offer the locating slot for being connected with edge bearing and/or blade pressuring plate buckle, on the surface of locating slot and/or phase dorsal part identical with chip breaking chip area on blade.
The center position of locating slot in blade.
Homonymy at blade has plural main cutting edge, in each main cutting edge, there is at least one pair of adjacent main cutting edge, chip breaking chip area corresponding to adjacent two main cutting edges dihedral intermediate location between the two be interconnected and form V-arrangement, circle, rhombus or square shared chip breaking chip area on both side surfaces of living in.
In the present invention, blade is superhard cutting blade, the surface of blade is provided with chip breaking chip area, chip breaking chip area is near the position of main cutting edge, in use, after main cutting edge cuts workpiece, smear metal meeting cut from surface of the work is flowed along the surface of blade, in the process of chip breaking chip area of flowing through, smear metal is produced convolution by the cell wall of chip breaking chip area and groove along stopping, and makes smear metal occur fractureing in the process of convolution, and smear metal is cut off; Simultaneously, chip breaking chip area can guide the flow direction of smear metal, make smear metal avoid the finished surface bending of workpiece as far as possible, thereby also played the effect of guiding chip removal, therefore in the present invention, chip breaking chip area can guide and cut off smear metal in smear metal processing, thus the tool sharpening quality of having avoided smear metal in prior art roll up on the front blade of superhard cutting blade considering to be worth doing and cause and the problem of machining accuracy decline.
