Description
Technical field
The utility model relates to tooling cost fields, and in particular to a kind of superhard cutter.
Background technique
At this stage, superhard brazed shank tool is there are mainly two types of production method, one is by diamond and cubic boron nitride with hard
Composite sheet is made through high temperature and pressure together in matter alloy, then composite sheet is soldered on hard alloy substrate；Another kind is by plycrystalline diamond
Diamond and polycrystalline cubic boron nitride, are soldered directly on hard alloy substrate.The cutter of two methods production, when cutter head is ground
After loss effect, which just fails.And be mostly a blade equipped with a cutter head, stock utilization is low.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides following technical scheme.
The utility model discloses a kind of superhard cutters, including cutter hub and matrix, and described matrix is equilateral triangle, described
It is equipped with a cutter hub at each angle of matrix, described matrix center is equipped with mounting hole, and the cutter hub includes cutter head and tool apron, described
Tip shapes are triangle, and one end of the tool apron is connect with cutter head, and the other end and the matrix of the tool apron are detachably connected, institute
It states cutter head and is connect with tool apron by HFI welding, the tool apron offers mounting groove far from cutter head one end, in described matrix
Equipped with installation rib, the mounting groove and the installation rib corresponding position are configured with spiral shell equipped with the identical screw hole of size, the screw hole
On nail and nut, the mounting groove and the installation rib, corresponding position is opened up there are two location hole, and described two location holes are matched
It is cased with positioning pin；
Further, the cutter head is PCD cutter head or PCBN cutter head, and the tool apron is hard alloy；
Further, for the cutter head with before the tool apron HFI welding, bit interface is electroplate with one layer 0.5 ~ 1 μm
Nickel adhesion layer.
The gain effect of the utility model is to set on same matrix there are three cutter head, tool bit abrasion can with rotary substrate after
Continuous to use, three cutter heads can replace the cutter hub on matrix, reduce the waste of material, after shortening tool bit abrasion after all wearing
Downtime, improve production efficiency.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model,
Fig. 2 is tool-apron structure schematic diagram,
Fig. 3 is base structure schematic diagram.
In figure: 1. matrixes, 11. mounting holes, 12. installation ribs, 2. cutter hubs, 21. cutter heads, 22. tool aprons, 221. mounting grooves, 3.
Positioning pin, 4. screws.
Specific embodiment
It is practical new to this with reference to the accompanying drawings and examples in order to be more clearly understood that the technical solution of the utility model
Type specific embodiment is described in further detail.The following examples illustrate the utility model, but is not limited to practical
Novel range.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of superhard cutter, including cutter hub 2 and matrix 1, described matrix 1 are equilateral triangle
Shape is equipped with a cutter hub 2 at each angle of described matrix 1, and 1 center of described matrix is equipped with mounting hole 11, and the cutter hub 2 includes knife
First 21 and tool apron 22,21 shape of cutter head is triangle, and one end of the tool apron 22 is connect with cutter head 21, the tool apron 22
The other end is detachably connected with matrix 1, and the cutter head 21 is connect with tool apron 22 by HFI welding, and the tool apron 22 is separate
21 one end of cutter head offers mounting groove 221, and described matrix 1 is equipped with installation rib 12, the mounting groove 221 and the installation rib 12
Corresponding position is equipped with the identical screw hole of size, and the screw hole is configured with screw 4 and nut, the mounting groove 221 and the installation
On rib 12, corresponding position is opened up there are two location hole, and described two location holes are configured with positioning pin 3；
Preferably, the cutter head 21 is PCD cutter head or PCBN cutter head, and the tool apron 22 is hard alloy；
Preferably, for the cutter head 21 with before 22 HFI welding of tool apron, 21 electroplating surface of cutter head has one layer 0.5
~ 1 μm of nickel adhesion layer improves the adhesion strength and wearability of cutter head 21 Yu tool apron 22, also improves heat-sinking capability, extend knife
First 21 service life.
When in use, 21 wear-out failure of cutter head, unscrews the screw at 1 mounting hole 11 of matrix, rotation matrix 1 makes not wear
Cutter head 21 is in operating position, then screws screw at 1 mounting hole 11 of matrix；It, can be more when three 21 equal wear-out failures of cutter head
Positioning pin 3 is first knocked out when replacing cutter hub 2 and unscrews screw 4 and nut again by tool changing body 2, and abrasion cutter hub 2 is removed, is loaded onto intact
Cutter hub 2, install cutter hub 2 when, first by 4 nut of screw connect, do not need reinforcing screw, then positioning pin 3 is knocked in, finally plus
Power tightening screw 4 and nut.
The utility model is set on same matrix there are three cutter head, and tool bit abrasion can be continued to use with rotary substrate, and three
Cutter head can replace the cutter hub on matrix after all wearing, reduce the waste of material, the downtime after shortening tool bit abrasion,
Improve production efficiency.
The above is the better embodiment of the utility model, therefore all according to described in the utility model patent application range
The equivalent change or modification that structure, feature and principle is done, is included in the scope of the utility model patent application.
