Abstract

The invention discloses a small-bore superhard boring tool and belongs to the field of mechanical cutting equipment. The small-bore superhard boring tool solves the problem that a small-bore boring tool can not be produced according to the prior art. The small-bore superhard boring tool comprises a boring tool handle and a cutting part, wherein the cutting part comprises a lining support and a blade, the section of the blade is triangular, the triangular surface of the blade is perpendicular to the axis of the boring tool handle and attached to the lining support, orthogonal clearance angle welding is adopted for the blade, and the diameter of the boring tool handle is smaller than 4 mm. The small-bore superhard boring tool is simple in structure. Due to the fact that the blade is perpendicular to the axis of the tool handle and orthogonal clearance angle welding is adopted for the blade, attaching area is increased, and strength is improved at the same time. A blade small in size can be selected as needed, the triangular surface of the blade is perpendicular to the axis of the boring tool handle and attached to the lining support, the small-bore superhard boring tool with bore diameter smaller than 4 mm can be produced, and actual production requirements can be met. The blade can be made of any superhard material, and cutting of various materials can be achieved. Meanwhile, the small-bore superhard boring tool can be repeatedly used and is not prone to abrasion, and production cost is saved.

Description

The superhard boring cutter in a kind of small-bore
Technical field
The present invention relates to machine cut process equipment field, specifically, particularly relate to the superhard boring cutter in a kind of small-bore.
Background technology
At present, along with science and technology is more and more flourishing, to the part in machine applications, processing request is also more and more higher.And boring is the internal diameter Cutting Process of a kind of cutter expanded hole or other circular contour, its range of application is generally from half roughing to fine finishining; But there is following shortcoming in boring cutter boring process at present: 1) when needing to process small-sized endoporus, current boring cutter is difficult to boring, 2) due to flexure that tangential force and radial load produce, boring cutter can be made easily to produce chatter, thus destroy the surface quality of workpiece, make surface of the work smoothness not reach requirement, be therefore badly in need of a kind of small-bore boring cutter and solve problems more of the prior art.
In prior art, superhard boring cutter blade is many to be made up of polycrystalline cubic boron nitride layer and diamond layer two disposable compactings of material layer, due to changing firmness requirements, the thickness of blade there are certain requirements, blade sections is triangle, the gore of blade is horizontally set on knife bar axis, and blade is positioned on the axis of boring cutter; In working angles, blade bears torsion, needs to set off to strengthen fixing, and due to blade self and set off thickness, therefore this blade laminating type cannot produce the boring cutter that aperture is less than the small-bore of 4mm.
Summary of the invention
The invention discloses the superhard boring cutter in a kind of small-bore, solving in prior art cannot the problem of production small-bore boring cutter, provides a kind of hardness high, constitutionally stable small-bore boring cutter.
The present invention is achieved by the following technical solutions:
The superhard boring cutter in a kind of small-bore, comprise boring cutter handle 1 and cutting portion 2, described cutting portion 2 comprises and sets off 3 and blade 4, the cross section of described blade 4 is triangle, the gore of described blade 4 perpendicular to boring cutter handle 1 axis with set off 3 laminatings, primary clearance welding made by blade 4, and described boring cutter handle 1 diameter is less than 4mm.
Described blade 4 is superhard material.
Described cutting portion 2 is also provided with groove 5.
Compared with prior art, the invention has the beneficial effects as follows:
Structure of the present invention is simple, and blade is with knife bar axes normal and blade adopts primary clearance to weld, and increases fitting area, improves intensity simultaneously; Can choose the little blade of size as required, the gore of blade is perpendicular to knife bar axis and set off laminating, can produce the superhard boring cutter in small-bore that aperture is less than 4mm, meet actual production demand; Blade can adopt various superhard material, is applicable to the machining of various material, simultaneously can Reusability, not easy to wear, has saved production cost.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
In figure: 1, boring cutter handle; 2, cutting portion; 3, set off; 4, blade; 5, groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described:
The superhard boring cutter in a kind of small-bore, comprise boring cutter handle 1 and cutting portion 2, described cutting portion 2 comprises and sets off 3 and blade 4, the cross section of described blade 4 is triangle, the gore of described blade 4 perpendicular to boring cutter handle 1 axis with set off 3 laminatings, primary clearance welding made by blade 4, and described boring cutter handle 1 diameter is less than 4mm, described blade 4 is superhard material, and described cutting portion 2 is also provided with groove 5.
As shown in drawings, the superhard boring cutter in a kind of small-bore, comprise boring cutter handle 1 and cutting portion 2, cutting portion comprises and sets off 3 and blade 4, and the interface of blade 4 is gore, the gore of blade 4 and the axes normal of boring cutter handle 1 and with set off 3 laminatings, primary clearance welding made by blade 4, and blade 4 adopts superhard material, is applicable to the machining of various material, cutting portion 2 is also provided with groove 5, facilitates machining.
The mode that blade 4 sets off 3 perpendicular to the axis laminating of boring cutter handle 1 is particularly applicable to production small-bore boring cutter, boring cutter aperture can be less than 4mm, the one side of blade 4 is arranged on the central axis of boring cutter handle 1, select undersized blade 4 according to demand, the gore of blade is perpendicular to boring cutter handle 1 axis and set off 3 laminatings, contact area is large, enhances the steadiness of boring cutter; Due to changing firmness requirements, blade has certain thickness requirement, the horizontal mounting means of blade cannot production small-bore blade, vertical axis mounting means saves space, select small size blade when blade thickness is constant, not only do not affect the working strength of boring cutter, and enhance the rigidity of boring cutter, prevent from fractureing, meet actual production demand.
Structure of the present invention is simple, and blade is with knife bar axes normal and blade adopts primary clearance to weld, and increases fitting area, improves intensity simultaneously; Can choose the little blade of size as required, the gore of blade is perpendicular to knife bar axis and set off laminating, can produce the superhard boring cutter in small-bore that aperture is less than 4mm, meet actual production demand; Blade can adopt various superhard material, is applicable to the machining of various material, simultaneously can Reusability, not easy to wear, has saved production cost.
In sum, be only preferred embodiment of the present invention, not be used for limiting scope of the invention process, all equalizations of doing according to shape, structure, feature and the spirit described in the claims in the present invention scope change and modify, and all should be included in right of the present invention.
