Abstract
The utility model discloses a CBN blade which comprises a blade body. The blade body is of an integrated structure and formed by pressing a whole cubic boron nitride blade. A chip discharge through hole is formed inside the blade body and comprises a longitudinal through hole body and two arc-shaped through hole bodies, wherein the longitudinal through hole body is a linear through hole body, the three through hole bodies are communicated with one another, the two arc-shaped through hole bodies are symmetrical about an axis with the cross section of the blade body serving as the reference face, the two arc-shaped through hole bodies are tangent to the longitudinal through hole body, and the arc angle alpha of the arc-shaped through hole bodies ranges from 55 degrees to 66 degrees. The two sides of the blade body are respectively provided with a square groove, wherein the two grooves are symmetrical about an axis. By forming the chip discharge through hole in a special arc shape, the problem that chip blocking is easily caused when chips are discharged is avoided; by forming the grooves in the two sides of the blade body, stability and fastening degree during clamping of the blade body are effectively improved.
Description
Technical field
The utility model relates to a kind of CBN blade, and particularly a kind of CBN blade, belongs to Metal Cutting technical field of tools.
Background technology
For current part of automobile engine processing industry, high accuracy, high-speed, high efficiency welded type polycrystalline cubic boron nitride turnning and milling boring cutter are by welding together with polycrystalline cubic boron nitride compound sheets and carbide alloy cutter hub, form simple welding blade and carry out shear action, but the damage that forms internal stress for cutter hub itself due to the high temperature in the time welding reduces cutter intensity.Due to cutter cutting speed at a high speed, there is strict will crying by gas for stability and the fastening degree of cutter clamping, and all the time, chip removal and inconvenience is all the great difficult problem of CBN cutter.The patent No. is: 201310504585.6 patent of invention provides a kind of integral type CBN blade, be provided with chip removal through hole therein, its chip removal through hole comprises a longitudinal hole and two cross through hole, and three through holes are connected, taking cutter hub cross section as datum level, described three chip removal through holes are
shape distributes.Although it is the interference effect of chip for cutting that this structure can subtract cutter cutting, but in actual use, researcher finds because longitudinal hole and cross through hole in this chip removal through hole are in vertical distribution, chip is when through through hole internal vertical angle, easily get congestion, long-time use can cause chip-removal hole to stop up, and is difficult to chip removal.Write this invention structure single, be not provided with any clamping structure, the stability of cutter clamping and fastening degree are not ideal enough.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of CBN blade for above drawback, arrange by special arc chip-removal hole, the chip blockage problem easily having caused while having avoided chip removal, and in cutter hub both sides, groove is set, the stability while effectively improving cutter hub clamping and fastening degree.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of CBN blade, comprise cutter hub, described cutter hub is integral type structure, adopt whole cubic boron nitride blade compacting to form, wherein, described cutter hub inside is provided with chip removal through hole, described chip removal through hole comprises a longitudinal hole and two arc-shaped through-holes, described longitudinal hole is straight line pylone, described three through holes are connected, and taking cutter hub cross section as datum level, described two arc-shaped through-holes arrange axisymmetricly, and described two arc-shaped through-holes and described longitudinal hole are tangent, the arc angle α of described arc-shaped through-hole is 55 degree-66 degree; Described cutter hub both sides are respectively provided with a groove, and described groove is square, and described two grooves arrange axisymmetricly.
Above-mentioned a kind of CBN blade, wherein, preferably, the arc angle α of described arc-shaped through-hole is 58 degree.
The beneficial effects of the utility model are:
1) adopt integral type structure of the cutter body, cutter hub consists of whole cubic boron nitride blade compacting, is different from original compound tool structure, saves welding sequence, the cutting tool directly processing.Eliminate by the high temperature in when welding and formed the damage of internal stress for cutter hub and reduce the impact of cutter intensity, thereby improved intensity and the wearability of cutter.Ensure machining accuracy and surface quality, enhanced productivity, greatly reduced enterprise and become to produce cost.
2) be provided with chip removal through hole, can in high-speed cutting process, keep even smooth chip removal, greatly reduce the interference effect that chip causes cutting, improve the result of use of blade.And arrange by special arc chip-removal hole, the chip blockage problem easily having caused while having avoided chip removal, ensures that chip removal is smooth and easy.
3) can obtain through up to ten thousand experimental tests, when the arc angle of arc-shaped through-hole is 58 while spending, it is fastest that chip is discharged in through hole, and be not easy to stop up.
4) in cutter hub both sides, groove is set, in the time of cutter hub clamping, can realizes effectively fastening fixing, the stability when shape of square groove can effectively improve cutter hub clamping and fastening degree by this groove.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, a kind of CBN blade, comprise cutter hub 1, described cutter hub is integral type structure, adopt whole cubic boron nitride blade compacting to form, wherein, described cutter hub 1 inside is provided with chip removal through hole 2, described chip removal through hole comprises a longitudinal hole 21 and two arc-shaped through-holes 22, 23, described longitudinal hole 21 is straight line pylone, described three through holes are connected, taking cutter hub 1 cross section as datum level, described two arc-shaped through-holes 22, 23 arrange axisymmetricly, and described two arc-shaped through-holes 22, 23 is tangent with described longitudinal hole 21, the arc angle α of described arc-shaped through-hole 21 is 55 degree-66 degree, described cutter hub 1 both sides are respectively provided with a groove 3, and described groove 3 is square, and described two grooves 3 arrange axisymmetricly, and preferably, the arc angle α of described arc-shaped through-hole 22,23 is 58 degree.
The beneficial effects of the utility model are: adopt integral type structure of the cutter body, cutter hub consists of whole cubic boron nitride blade compacting, is different from original compound tool structure, saves welding sequence, the cutting tool directly processing.Eliminate by the high temperature in when welding and formed the damage of internal stress for cutter hub and reduce the impact of cutter intensity, thereby improved intensity and the wearability of cutter.Ensure machining accuracy and surface quality, enhanced productivity, greatly reduced enterprise and become to produce cost.Be provided with chip removal through hole, can in high-speed cutting process, keep even smooth chip removal, greatly reduce the interference effect that chip causes cutting, improve the result of use of blade.And arrange by special arc chip-removal hole, the chip blockage problem easily having caused while having avoided chip removal, ensures that chip removal is smooth and easy.Can obtain through up to ten thousand experimental tests, when the arc angle of arc-shaped through-hole is 58 while spending, it is fastest that chip is discharged in through hole, and be not easy to stop up.In cutter hub both sides, groove is set, in the time of cutter hub clamping, can realizes effectively fastening fixing, the stability when shape of square groove can effectively improve cutter hub clamping and fastening degree by this groove.
