Abstract
A kind of multiple tooth diplocardia diameter milling cutter, including cutter tooth, cutter hub, knife handle and the deep trouth and shallow slot being arranged on cutter hub, tool bit part is provided with deep trouth on the cutter hub, shank portion is provided with shallow slot, the deep trouth and shallow slot are longitudinally disposed each along cutter hub and be correspondingly connected with, deep trouth slot bottom is made of arc surface of two concave surfaces into slot, and the central angle constituted between the cutter tooth two cutters tooth adjacent thereto is unequal.Space is big and slot bottom is round and smooth since appearance is cut for the invention cutter, iron filings can be discharged glibly very much, quickly cutting heat is taken away, reduce the damage of the time of contact and cutting heat of iron filings and cutter to cutter, significantly reduce the abrasion of cutter, it is, so as to improve due to cutting edge roundness abrasion condition caused by resonating, to reduce the roughness of piece surface to reduce this cutter by the resonance between part to be processed during actual cut there are also being exactly using the design of unequal blade spacing.
Description
Technical field
The present invention is a kind of milling cutter, and in particular to a kind of multiple tooth diplocardia diameter milling cutter.
Background technique
Milling cutter is to be mainly used for adding on milling machine for Milling Process, the rotary cutter with one or more cutters tooth
Work plane, step, groove, forming surface and cutting workpiece etc..Currently, to cut space small for the generally existing appearance of common milling cutter in the market
And the problem of causing iron filings exclusion to have some setbacks, it is exactly also that cutting edge roundness serious wear causes work piece surface roughness big,
Furthermore it is exactly that milling efficiency is low, the short disadvantage of service life.These disadvantages keep milling cutter tool very inconvenient at work, to processing
Work causes to hinder, and reduces working efficiency and part processing quality is made to have a greatly reduced quality.Therefore it provides a kind of easy to use, longevity
Life is long, it is small to wear, while can improve processing efficiency but also improve the milling cutter of part processing quality and be particularly important.
Summary of the invention
To solve the above problems, being worked the object of the present invention is to provide a kind of multiple tooth diplocardia diameter milling cutter with solving cutter
In the process it is existing it is inconvenient to use, abrasion is big, the service life is short, the low problem low with processing quality of working efficiency.
Technical solution provided by the invention is a kind of multiple tooth diplocardia diameter milling cutter, including cutter tooth, cutter hub, knife handle and setting
Deep trouth and shallow slot on cutter hub are provided with deep trouth close to tool bit part on the cutter hub, and shank portion is provided with shallow slot,
The deep trouth and shallow slot are longitudinally disposed each along cutter hub and be correspondingly connected with, circular arc of the deep trouth slot bottom from two concave surfaces into slot
Face forms, and the difference of the central angle constituted between cutter tooth two cutters tooth adjacent thereto is 3o ~ 9o.
The groove depth of the deep trouth is the 21% ~ 30% of sword diameter D, the 20% ~ 50% of a length of total long L of sword of sword.
Radius of circle value range corresponding to two arc surfaces of the deep trouth slot bottom is 0.3mm ~ 6mm.
The groove depth of the shallow slot is the 10% ~ 20% of sword diameter.
The beneficial effects of the present invention are the preceding part deep trouth of, the invention cutter have sufficiently large appearance cut space and by
The round and smooth degree of the slot bottom of arc surface composition can also improve, and the intensity of cutter can be effectively ensured in rear part shallow slot, and this cutter is in reality
Can be cut greatly in the cutting process of border wide, big cutting-in, fast feed highly-efficient processing, milling efficiency be other ordinary cutting tools
3~5 times；Further, since appearance is cut, space is big and slot bottom is round and smooth, and iron filings can be discharged glibly very much, quickly by cutting heat band
It walks, reduces the damage of the time of contact and cutting heat of iron filings and cutter to cutter, significantly reduce the abrasion of cutter, make
It is 2~3 times longer than other ordinary cutting tools to obtain this cutter life；It is to make there are also being exactly using the design of unequal blade spacing
This cutter reduces the resonance between part to be processed during actual cut, so as to improve due to tool blade caused by resonating
Mouth abrasion condition, reduces the roughness of piece surface.
Detailed description of the invention
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing.
Fig. 1 is the main view of multiple tooth diplocardia diameter milling cutter；
Fig. 2 is the left view of multiple tooth diplocardia diameter milling cutter；
Fig. 3 is the cross-sectional view in Fig. 1 along A-A cutting；
As shown, 1- cutter tooth, 2- deep trouth, 3- shallow slot, 4- cutter hub, 5- knife handle.
Specific embodiment
As described below is only the preferable embodiment of the present invention, thus construction described in all present patent application ranges, feature and
The equivalent change or modification that principle is done is both contained in the range of the invention patent.
As shown in attached drawing 1,2 and 3, a specific embodiment of the invention be a kind of multiple tooth diplocardia diameter milling cutter, including cutter tooth 1,
Cutter hub 4, knife handle 5 and the deep trouth 2 and shallow slot 3 being arranged on cutter hub 4 are provided with deep trouth 2 close to tool bit part on cutter hub 4,
5 part of knife handle is provided with shallow slot 3；Deep trouth 2 and shallow slot 3 are longitudinally disposed each along cutter hub 4 and be correspondingly connected with；2 slot bottom of deep trouth
It is made of arc surface of two concave surfaces into slot；The difference of the central angle constituted between 1 adjacent thereto two cutter tooth 1 of the cutter tooth is
3o ~ 9o, such as α fillet and ε fillet, ε fillet and δ fillet, δ fillet and γ fillet, γ fillet β fillet and β fillet and α fillet
Differential seat angle between is 3o ~ 9o.
The groove depth of the deep trouth 2 is the 21% ~ 30% of sword diameter D, the 20% ~ 50% of a length of total long L of sword of sword.
Radius of circle value range corresponding to two arc surfaces of 2 slot bottom of deep trouth is 0.3mm ~ 6mm, such as radius
The value range of the U-type groove bottom for the arc surface composition that arc surface and radius for R1 are R2, R1 and R2 are 0.3mm ~ 6mm.
The groove depth of the shallow slot 3 is the 10% ~ 20% of sword diameter D, and sword diameter of the present invention refers to cutter tooth outermost edge around knife
The rotation of body center is formed by circular diameter.
In use, facing cutter is by key and axis connection, when power passes to band by V band by milling cutter on facing cutter
Wheel, passes to axis through key, and facing cutter can be driven to turn, and carries out Milling Process to part.
