Abstract
The present invention relates to the superhard cutting blade of a kind of band chip-breaker, cutter head is welded on matrix, is provided with the chip-breaker less than surface cutting edge on cutter head.Blade can be disposable type in iso standard, it is alternatively the special shape special type of customization, blade uses hilted broadsword head or multi-knife-head design, each bit interface all can processed broken chip groove, can be according to the different chip-breaker angle of different model insert design and chip-breaker shape with the use of applicable actual condition and processing request.The present invention efficiently solves continuous print chip in production process and makes workpiece scratch or be wound around the problem of cutter, reduces the probability that cutter heel and toe wear damages, and meets the requirement of high-speed and high-efficiency cutting.Present invention is mainly used for, space flight, automobile, machine-building, non-ferrous metal products, the processing of hardened steel goods in boats and ships and chemical industry.
Description
Technical field
The present invention relates to the superhard cutting blade of a kind of band chip-breaker, belong to machinery and field of tool.
Background technology
The density of fine aluminium is little (ρ=2.7g/cm3), about the 1/3 of ferrum, fusing point low (660 DEG C), therefore it is unfit to do structural wood
Material, but can be made into various aluminium alloy, such as duralumin, superduralumin, rustproof aluminum alloy, cast aluminium etc..The aluminium alloy adding the formation of certain element is being protected
Can also have higher intensity while holding the advantages such as fine aluminium light weight, σ b value is respectively up to 24～60kgf/mm2.So make it
" specific strength " (intensity and the ratio σ b/ ρ of proportion) surpasses a lot of steel alloy, becomes preferable structural material, is also should in industry
With a widest class non-ferrous metal structural material, in Aeronautics and Astronautics, automobile, machine-building, boats and ships and chemical industry
Widely apply.
But aluminium alloy is in the course of processing, produced aluminum bits into strips and are not easy to disconnect, and cause winding workpiece to make work
Part surface tear or winding cutter cause tipping.As aluminium alloy, hardened steel is relatively easy to produce in the course of processing and is similar to
Problem.
Solve these problems produced in the course of processing, not only to select suitable cutter material, also to select to close
Suitable cutting edge roundness, geometric parameter are with the chip breaking of improvement of cutter and chip removal performance.
Summary of the invention
In order to overcome the deficiency of prior art construction, according to the work in-process difficulty chip breaking such as aluminium alloy, hardened steel, it is very easy to
Producing continuous print chip and continuously chip easily makes surface of the work scratch or cutter tipping, and working (machining) efficiency is low etc. asks
Topic, the present invention provides the superhard cutting blade of a kind of band chip-breaker.
The technical solution adopted for the present invention to solve the technical problems is: cutter head is welded on matrix, and bit interface has sword
Mouthful, there is a chip-breaker at each cutting edge post-treatment.
Described chip-breaker (3) is the concave chip-breaker less than cutting edge (4).
The angular range of the chip-breaker angle [alpha] formed between described cutting edge and chip-breaker is at 15 °-25 °.
The curved shape of described chip-breaker.
Present invention is mainly used for, space flight, automobile, machine-building, non-ferrous metal products, quenching in boats and ships and chemical industry
The processing of steel part.
The benefit of the present invention is: uses chip-breaker design, efficiently solves continuous print chip in production process and make workpiece draw
Wound or the problem of winding cutter, reduce the probability that cutter heel and toe wear damages, meet the requirement of high-speed and high-efficiency cutting.Can
The chip-breaker angle different according to different model insert design and chip-breaker shape are wanted with using and processing of applicable actual condition
Ask.

Detailed description of the invention
When considered in conjunction with the accompanying drawings, and by referring to detailed description below, it is possible to be more completely more fully understood that the present invention
And easily learn the advantage that many of which is adjoint, but accompanying drawing described herein is used for providing the further reason to the present invention
Solving, constitute the part of the present invention, the schematic description and description of the present invention is used for explaining the present invention, is not intended that this
The improper restriction of invention.
With reference to Fig. 1-Fig. 4, structure is implemented in shown invention two kinds.The present invention is the superhard cutting blade of a kind of band chip-breaker, cutter
2 are welded on matrix 1, and there is cutting edge 4 on cutter head 2 surface, have a concave less than cutting edge 4 to break at each cutting edge 4 post-treatment
Bits groove 3, the described curved shape of chip-breaker 3, it is beneficial to chip breaking and chip removal.
Below two kinds of embodiments are illustrated respectively:
Embodiment 1: as it is shown in figure 1, blade shapes is rectangle, for D type blade in iso standard.Use Welding by cutter
2 are welded on matrix 1.On cutter head 2 surface, it is chip-breaker 3 that the angle of rectangle has cutting edge 4, the female after cutting edge 4.
Chip-breaker 3 is that the method using laser engraving forms in cutter head 2 Surface Machining.
As shown on the enlarged drawing of Fig. 2, the angular range of the chip-breaker angle [alpha] formed between cutting edge 4 and chip-breaker 3 exists
15 °-25 °.
Embodiment 2: as it is shown on figure 3, blade shapes is many prismatics, for H type blade in iso standard.Employing Welding will
Cutter head 2 is welded on matrix 1.On cutter head 2 surface, it is chip-breaker 3 that corner angle have cutting edge 4, the female after cutting edge 4.Chip breaking
Groove 3 is also that the method using laser engraving forms in cutter head 2 Surface Machining.
As shown in the enlarged drawing of Fig. 4, between cutting edge 4 and chip-breaker 3 formed chip-breaker angle [alpha] angular range 15 °-
25°。
The blade of the present invention can be disposable type in iso standard, it is possible to for the special shape special type of customization.
The tool tip material of superhard cutting blade can use PCD, PCBN bi-material.PCD is mainly used in processing aluminium alloy etc. to be had
Non-ferrous metal material, PCBN is mainly used in processing the material such as hardened steel or cast iron.
Blade uses hilted broadsword head or multi-knife-head design, each bit interface all can processed broken chip groove, and chip-breaker is by spy
Different geometry composition.Chip-breaker angle and chip-breaker shape can do different designs, processing according to different model blade.Each breaks
Bits groove both can be symmetrical, it is also possible to mal-distribution.
Principle and the embodiment of the present invention are set forth by specific embodiment used herein, above example
Method and the core concept thereof being only intended to help to understand the present invention is described；Simultaneously for one of ordinary skill in the art, depend on
According to the thought of the present invention, the most all will change.In sum, this specification content
Should not be construed as limitation of the present invention.
