Abstract

The utility model discloses a composite blade which comprises a substrate which is column-shaped and is made of hard alloy materials, protruding portions which are column-shaped are arranged on the end surface of the substrate, the outer circumferences of the protruding portions and the end surface of the substrate define an annular step surface which encircles the outer circumferences of the protruding portions, and annular cutting blocks which are made of the polycrystalline superhard materials are fixedly arranged on the step surface in a welded or sintered mode. The cutting portion which is arranged on a blade body and used for cutting workpieces is made of polycrystalline superhard materials, other cutting portions which are not used for cutting the workpieces are made of the hard alloy materials, and the content of the polycrystalline superhard materials of each blade body is reduced under the condition that the normal using effect of each blade body is not influenced. Therefore, the polycrystalline superhard materials can be saved, and the overall manufacturing cost of the blade body is reduced.

Description

A kind of composite blade

Technical field

The utility model relates to the cutting-tool engineering field.

Background technology

At present, the glomerocryst superhard material has high hardness and wearability, and coefficient of friction is little, the thermal conductivity height, be difficult for producing built-up edge during cutting, the blade that usually adopts the glomerocryst superhard material to make thus carries out machining to non-ferrous metal material and nonmetallic materials, as copper, non-ferrous metal and alloys thereof such as aluminium, pottery, unsintered carbide alloy, the nonmetallic materials such as composite that various fibers and particle are strengthened, but because the whole blade of being made by the glomerocryst superhard material is when cutting, the part that is used for cutting on the blade only is the edge part of blade, and the main part that is in the blade mid portion is in whole cutting process, be what not participate in the machining of workpiece, when the edge of blade part is damaged inefficacy, whole blade has also just been scrapped, this has just caused the waste to the glomerocryst superhard material that is in the blade middle part, and has improved the overall cost of blade.

The utility model content

The purpose of this utility model provides a kind of composite blade of saving material.

In order to realize above purpose, the technical scheme of composite blade of the present utility model is as follows:

A kind of composite blade, the matrix that comprises the column of being made by Hardmetal materials, the end face of matrix is provided with the protuberance of column, the outer peripheral face of protuberance and the end face of matrix surround the step surface that is centered around the annular on the described protuberance periphery, weld or be sintered to fix the cutting piece of the annular of being made by the glomerocryst superhard material at described step surface.

Described protuberance has two and be on the two ends end face of matrix.

Described matrix is columned cylinder, and described protuberance is the cylindrical boss with the coaxial setting of matrix.

Offer the installing hole that connects the two ends end face on the described matrix.

Described cutting piece is the block that is formed by the cubic boron in the glomerocryst superhard material or dimond synneusis sintering.

The main body of blade is the matrix of being made by Hardmetal materials in the utility model, end face at matrix is provided with protuberance, the outer peripheral face of protuberance and the end face of matrix surround the step surface that is centered around the annular on the described protuberance periphery, in this step surface, weld or be sintered to fix the cutting piece of the annular of being made by the glomerocryst superhard material, thereby make the cutting tip that is used for cutting workpiece on the blade be made by the glomerocryst superhard material, other parts that do not participate in cutting are then made by Hardmetal materials, make under the situation that does not influence the normal result of use of blade, reduced glomerocryst superhard material content on each blade, save the glomerocryst superhard material, reduced the overall cost of blade; And the cutting ring end face of piece and internal face are all and matrix bond, make the bonded area of cutting piece and matrix increase, thereby improved cutting piece and the fixing fastness of matrix in the blade, and guaranteed whole blade reliability in use.

The specific embodiment

The embodiment 1 of composite blade of the present utility model: as depicted in figs. 1 and 2, this composite blade comprises the cutting piece 2 of the annular that inlay at the two ends, the left and right sides of the columned matrix 1 made by Hardmetal materials and matrix 1, wherein be respectively equipped with the projection 11 of column on the both ends of the surface of matrix 1, the outer peripheral face of projection 11 and the end face of matrix 1 surround the step surface that is in the annular on described protruding 11 peripheries; The cutting piece 2 be to be formed by the polycrystalline cubic boron nitride sintering in the glomerocryst superhard material, and the cutting piece 2 be sintered to fix on the described step surface so that the cutting piece 2 ring end face and internal face be combined on the matrix respectively.

The cutting piece of being made by the glomerocryst superhard material in the composite blade of present embodiment 2 is because having compatibility preferably with superhard alloy, but direct sintering is on superhard alloy, and the main body that makes blade is the matrix of being made by Hardmetal materials 1, make under the situation that does not influence the normal result of use of blade, reduced glomerocryst superhard material content on each blade, save the glomerocryst superhard material, reduced the overall cost of blade; And the cutting ring end face of piece 2 and internal face are all and matrix bond, make the bonded area of cutting piece 2 and matrix 1 increase, thereby improved the fixing fastness of cutting piece 2 and matrix in the blade 1, and guaranteed whole blade reliability in use.

The embodiment 2 of composite blade of the present utility model: as shown in Figure 3 and Figure 4, the difference of present embodiment and embodiment 1 is, in the present embodiment, the centre bore 23 that extends about offering on the matrix 21, and the axis of the axis of centre bore 23 and two cutting pieces 22 overlaps, and the two ends end face of matrix 21 is run through at the two ends of centre bore 23.

In the above-described embodiments, the cutting piece is to adopt the polycrystalline cubic boron nitride in the glomerocryst superhard material to make, and in other embodiments, described glomerocryst boron nitride material also can use other glomerocryst superhard materials such as polycrystalline diamond, glomerocryst corundum to replace.

In the above-described embodiments, matrix is columned, corresponding cutting piece is circular, to adapt to grinding, in other embodiments, matrix also can be other column structures such as flat column, triangle column, and the shape of cutting piece can keep circular, also can be other shapes similar with base shape.

In the above-described embodiments, matrix is provided with two cutting pieces, when to cut piece in an end-grain cutting of matrix breakage taking place, can continue processing by the matrix of turning round, in other embodiments, the cutting piece on the matrix also can be one, and corresponding cutting piece also can only be arranged on the end end face of matrix.
