Abstract
The utility model relates to a novel brazed polycrystalline cubic boron nitride quadrangular milling blade, which effectively solves the problems of poor surface quality of the processed workpiece by the cutting tool, quick rear surface abrasion of the cutting tool and short service life. The utility model adopts the technical proposal that the milling blade comprises a blade and a cutter body, wherein, the blade is a composite long flat body made of polycrystalline cubic boron nitride, the cutter body is a quadrangular flat square body made of cemented carbide, the blade is welded on in the concave plane at one side part of the cutter body, the auxiliary cutting edge A of the blade is of a circular arc shape, the radius of the circular arc is 100 mm, and the cutting edge of the blade is a curve. The utility model has novel and unique structure, convenient installation and use, improves the surface quality of the workpiece, reduces the flank wear of the cutting tool, prolongs the service life of the cutting tool and has remarkable economic and social benefits.
Description
One, technical field
The utility model relates to cutter, particularly a kind of welding polycrystalline cubic boron nitride quadrangle cutter blade.
Two, background technology
Metal part processing be unable to do without cutter, particularly along with the improvement of development of science and technology and material, require more and more higher to process tool, with processing diesel engine engine cylinder-body end face is example, the cutter that uses is to adopt welding polycrystalline cubic boron nitride (PCBN) quadrangle cutter blade at present, be welded by polycrystalline cubic boron nitride composite sheet and carbide alloy cutter hub, be mainly used in the processing of diesel motor cylinder end face, but because the problem on the cutter structure, particularly the front cutting edge place of cutter is straight sword, and the workpiece surface quality of processing is poor, and the cutter flank wear is fast, life-span is short, and it is imperative that cutter improves.
Three, utility model content
At above-mentioned situation, for overcoming the prior art deficiency, the utility model purpose just provides a kind of novel welding polycrystalline cubic boron nitride quadrangle cutter blade, the workpiece surface quality that effectively solves cutter processing is poor, the cutter flank wear is fast, the problem that service life is short, the technical scheme of its solution is, include blade and cutter hub, blade is the flat body of compound length that polycrystalline cubic boron nitride is made, and cutter hub is the quadrangle flat-square shaped that carbide alloy is made, blade is welded in the concave plane of cutter hub one sidepiece, the front cutting edge A of blade is circular-arc, and the radius of its circular arc is 100mm, and blade cutting edge is curved.The utility model novel structure uniqueness, easy to install, improve workpiece surface quality, reduce the wearing and tearing of cutter back, prolong cutter life, economic and social benefit is remarkable.
Four, description of drawings
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is a structure side view of the present utility model (left view).
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
Provide by Fig. 1,2, the utility model includes blade and cutter hub, blade is the flat body of compound length that polycrystalline cubic boron nitride is made, cutter hub is the quadrangle flat-square shaped that carbide alloy is made, blade 1 is welded in the concave plane of cutter hub 2 one sidepieces, the front cutting edge A of blade is circular-arc, and the radius of its circular arc is 100mm, and blade cutting edge is curved.
In order to guarantee result of use and easy maintenance and installation, on said cutter hub 2 front-backs step-like through hole 3 is arranged, the cutter hub rear portion is the obtuse angle for two jiaos, the blade blade is a meander-like.
By said structure as can be seen, the utility model is that the science of existing cutter is improved, particularly the front cutting edge A place with former cutter changes the arc that arc radius is 100mm into for straight sword, the wearing and tearing of cutter back have been reduced greatly, prolonged service life, and effectively improved the quality of work piece surface, and reduced the cutter use cost, be that one on the cutter created greatly.
