Description
Technical field
The present invention relates to a kind of cutter, a kind of ratchet structure Integral milling cutter for composite processing.
Background technology
Present stage composite is widely used in airplane design, in the course of processing to composite, typically adopts
With ripple milling cutter, herringbone milling cutter and drilling cutters, such cutter can be only done its edge when to composite processing
Cutting and drilling, it is impossible to realize the processing to composite material surface groove class shape.Present stage, as groove class shape added man-hour, adopts
With the flute profile cutter of processing steel class part, but such cutter is in the course of processing, easily occurs that tool wear is serious, processing dimension
Undesirable, the features such as the processing life-span is low, it is impossible to meet composite processing requirement.
Summary of the invention
The defect existed for above-mentioned technology, the present invention proposes and can improve edge strength, and the processing increasing cutter makes
With a kind of ratchet structure Integral milling cutter for composite processing in life-span.
A kind of ratchet structure Integral milling cutter for composite processing, by handle of a knife, cutter hub, cutting tooth and corundum four
Part composition, described handle of a knife is connected with cutter hub；Described cutter hub profile is annular, and described handle of a knife profile is cylindrical, described in cut
Cutting tooth is ratchet shape, and described cutting tooth is assemblied on cutter hub, and described corundum is plated on cutting tooth.
Described handle of a knife passes through round-corner transition with the junction of cutter hub.
In ratchet-like after described cutting tooth and cutter hub combination.
The ratchet structure Integral milling cutter of the composite processing of the present invention, this ratchet structure Integral milling cutter is by handle of a knife and cutter hub
Two parts form, and cutter hub is made up of 8 cutting edges, in cutting edge design process, use positive-angle anterior angle, it is ensured that cutting edge
Sharpness；Using wide-angle relief angle, with the frictional force of knife face after reducing with processing part, this kind of design also ensure that cutting edge
Sharpness；Additionally for ensureing the intensity of cutting edge, " blade operative part HRC (63-66), shank allows as HRC (50-in employing
55) heat treatment mode ", this kind of mode not only ensure that the intensity of cutting edge, and reduce the difficulty of heat treatment.Heat treatment
After, use the mode of sharpening, improve the sharpness of cutting edge further, thus ensure that the machinability of cutter.For increasing cutter
The antiwear property of tool, at knife edge part plated with gold emery, makes part, chip be changed into part and corundum with the friction of cutter
Friction, thus avoid zero, the friction of chip part and metallic matrix, it is ensured that the working durability of cutter.
Composite is typical difficult-to-machine material, during machining, it is necessary to assure tool strength is high, cutting edge is sharp and
Wearability is good.
For improving the intensity of cutter, special selection intensity is high, and red hardness is good, and wearability is high, and hardenability is good
W6Mo5Cr4V2Al, as tool matrix, selects the heating strength requirement of HRC (63-66) simultaneously, thus ensure that cutter
Requirement of strength, because of this strength of materials, needs to customize the higher cutter of intensity in the course of processing and completes the profile of this cutter and be correlated with
The processing of size.For ensureing that cutting edge has enough sharpness, intending using positive-angle anterior angle and wide-angle relief angle, this kind sets
Meter also ensure that the sharpness of cutting edge, thus ensure that the machinability of this cutter in anterior angle and the relief angle course of processing,
Because cutting edge is non-regular shape, the course of processing is wayward, need to customize relevant tool and complete the processing of tool orthogonal rake and relief angle.
For improving the abrasion resistance of cutter, cutting edge need to be carried out local strengthening, reduce and even avoid part, chip and tool matrix
Friction, improves the wearability of cutter, it is ensured that cutting-tool's used life.Improving cutter life, reducing tool wear, intend adopting
Chemically, completing the plating of coating, elite corundum is as the coating of plating.
The invention has the beneficial effects as follows:
The present invention can not only ensure that sharpness and the intensity of cutting edge；The wearability of cutter can also be improved, and then
Ensure that cutting-tool's used life.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the front view of the present invention；
Fig. 2 is the left view of the present invention.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below right
The present invention is expanded on further.
As depicted in figs. 1 and 2, a kind of ratchet structure Integral milling cutter for composite processing, by handle of a knife 2, cutter hub 1,
Cutting tooth 3 and corundum 4 four part composition, described handle of a knife 2 is connected with cutter hub 1；Described cutter hub 1 profile is annular, described
Handle of a knife 2 profile is cylindrical, and described cutting tooth 3 is ratchet shape, and described cutting tooth 3 is assemblied on cutter hub 1, and described corundum 4 plates
Overlay on cutting tooth 3.
Described handle of a knife 2 passes through round-corner transition with the junction of cutter hub 1.
In ratchet-like after described cutting tooth 3 and cutter hub 1 combination.
The occupation mode of all parts of the present invention is as follows:
1) cutter hub 1 profile is annular, connects handle of a knife 2, and supports cutting tooth 3, revolves with handle of a knife 2 in working angles
Turn, and completed cutwork by cutting tooth 3.
2) handle of a knife 2 profile is cylindrical, is connected with cutter hub 1, and is assemblied in lathe handle of a knife, rotates with machine tool chief axis,
Cutter hub 1 is driven to rotate, it is ensured that persistently carrying out of cutting.
3) cutting tooth 3 is ratchet shape, is assemblied on cutter hub 1, and cutter hub 1 rotates, and in working angles, directly connects in workpiece
Touch, complete the cutwork to workpiece.
4) corundum 4 plating is with on cutting tooth 3, rotates with cutting tooth 3, it is to avoid cutting tooth 3 directly in
Absorption surface, adds the abrasion resistance of cutting tooth 3.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technology of the industry
The personnel simply present invention it should be appreciated that the present invention is not restricted to the described embodiments, described in above-described embodiment and description
Principle, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these change and
Improvement both falls within claimed invention.Claimed scope is by appending claims and equivalent circle thereof
