Description
Technical field：
The present invention relates to a kind of broaching tool, which is used in the mechanical processing of the Gear Production of lathe etc., and new machinery adds
Work theory thinks that segmentation i.e. stepped cutting edge stock-removing efficiency is high, however after the gradual extension of stepped cutting edge it finds that its
It is with obvious effects to decline until disappearing, therefore the theory is not still truly correct theory.
Background technology：
At present, the broaching tool used in mechanical processing is being fed by the compositions such as cutting blade and the shank of tool, the cutting edge of broaching tool
On direction, there is unicity stress, i.e., be single curve-like or linear on a cutting edge, by single cutting edge
It forming, the cutting way resistance of this kind of cutting edge is big, causes whole destructiveness big, thus tipping easily occurs, beats accident living, and
Waste product is easily caused, brings very big loss, the more serious or even universal understanding of accident people that causes casualties is that surface is got over
Flat strength is higher, and new theory is then the surface intensity higher for having minim gap, all the inherent structural characteristics without exposure substance,
Therefore, existing aperture knife tool efficiency is low, and fragile, stability is poor, and borehole accuracy is poor.
Invention content：
The present invention be exactly in view of the above-mentioned problems and propose, by provide one kind divide diameter displacement broaching tool for the purpose of, this kind of knife
Have the function of to block conductance, radiating efficiency is high, and intensity is big, long lifespan, and easily positions when drilling is processed, drilling essence
Degree is high, and the universal understanding of people is that surface more flat strength is higher, and the new theory of recent years is then the face for having minim gap
Intensity higher, all inherent structural characteristics without exposure substance, in the case where two solid volumes are identical, wherein be dispersed into
The surface area of the solid of small size is more than the surface area of whole solid, when the overall structure of solid reaches the certain volume limit i.e.
Make be diamond also can fragmentation, by volume stress in the case of small size the sum of solid stressed intensity much larger than whole solid
Stress intensity, by experimental verification on the cutting element under usual physical state, millimeter magnitude has most apparent high intensity
Characteristic, that is, millimeter intensity, the present invention are that diameter displacement broaching tool is being divided to carry out the application with millimeter intensity.
The present invention is exactly to propose in view of the above-mentioned problems, for the purpose of a kind of novel broaching tool to be provided, this kind of cutter
Stock-removing efficiency is high, and intensity is big, long lifespan, and safe in cutting workpiece, smaller to lathe destructiveness.
In order to achieve the above object, the present invention uses following technical proposals：
A kind of broaching tool, has the shank of tool and cutterhead, and the shank of tool and cutterhead couple or be formed as one, cutterhead one
Be provided with to body multiple cutting blades, on each cutting blade, have one towards the face of cutting direction be cutting face, cutting face
Side or back side are rear cutting face or lateral incision bevel below, cutting face and rear cutting face or lateral incision bevel, be crossed to form to
A few cutting edge or at least one side cutting edge；
There is no infinitely great solid in cosmic space, when any huge solid reaches the volume limit, i.e., some is fixed
Under the conditions of atom vibratory forces summation and solid structure insist on should be usually this kind of solid under this condition maximum volume, be more than
This volume structure solid will be unable to maintain complete solid structure, when the overall structure of solid reaches the certain volume limit i.e.
Make be diamond also can fragmentation, even if neutron star or black hole are no exception, in the environment of people's everyday exposure, the volume of solid
The limit is influenced by temperature and terrestrial gravitation, and limiting volume is relatively much smaller, and when solid volume, it is strong in the case of reduction
Degree but in appropriate enhancing, wherein millimeter intensity be than more prominent example, according to two solid volumes it is identical in the case of,
In be dispersed into surface area of the sum of the surface area of solid of small size more than the solid of equivalent entirety, the overall structure of solid reaches
Even during the certain volume limit diamond also can fragmentation, by volume stress in the case of small size the sum of solid stressed intensity
Much larger than the stress intensity of whole solid, under usual physical state, millimeter magnitude is the most apparent high intensity of solid of the same race

Cutting edge is divided with micro- cutting blade 7 with millimeter intensity that rear cutting face is crossed to form in micro- enhancement stress extension platform 6 and micro- section 5
It opens, and conductance is broken up, reduce whole cutting force, maximally reduced outside cutting face and rear cutting face
The stress effect of intersecting cutting edge and cutting edge, reduces cutterhead temperature, decomposes the cutting edge of the most flimsy outer end of cutter
Stress, extend cutter life, and be always maintained at high intensity in process.
Although above to be illustrated for the broaching tool of shank of tool positioning or location hole positioning, the cutter of the present invention
It can also be used for setting stair-stepping combined cut face or stair-stepping compound rear cutting face or rank on the cutting face of all broaching tools
The compound lateral incision bevel of scalariform forms at least combined cutting edges of step shape or compound side cutting edge, cutting edge or lateral incision
Cut and recess sword be provided on sword, extended to form in opening to cutting face or lateral incision bevel or rear cutting face as groove, cutting edge or
Be provided on side cutting edge or combined cutting edges or compound side cutting edge recess sword in opening to cutting face or lateral incision bevel or
Cutting face extends to form the broaching tool of the multiple combinations of the mode for groove afterwards.
Above-described preferred embodiment is illustrative rather than restrictive, in the master for not departing from the present invention
