Description
Technical field
The present invention relates to alloy bar knives, and in particular to a kind of removable alloy bar knife.
Background technology
Alloy bar cutter is mainly used for processing the essences such as turbine blade, impeller, auto parts and components and medical instrument, aviation
Close complex parts.Wherein, numerical control alloy bar knife is the bar tool of current more mainstream.It is shaped with one or more
In the forming machine of station, the first forming station is frequently used to shape the one section of bar cut from a bar.The shearing of bar
Usually one, individually shearing station is realized by means of a fixed bar knife and its opposite moveable scissors, is moved
Scissors by one shearing sliding block be allowed to move back and forth.In order to constitute bar knife and scissors, it has been known that there is various possibilities.In cold forming
Closed circular knife is for example used as bar knife and scissors in machine.Bar to be sheared is pushed into the opening of bar knife and scissors
In, then scissors rapid vertical is moved in bar, cuts one section of bar whereby.Existing alloy bar knife cutter head and blade one
Chemical conversion type, in tool bit abrasion can only Disposal together, cause serious waste.
Invention content
The technical problem to be solved by the present invention is to existing alloy bar knife cutter heads and blade integrated molding, in cutter head
When abrasion can only Disposal together, cause serious waste, and it is an object of the present invention to provide a kind of removable alloy bar knife, in solution
State problem.
The present invention is achieved through the following technical solutions：
A kind of removable alloy bar knife, including alloy bar knife, blade and the cutter head of the alloy bar knife are can
Disassembly and assembly structure, blade are connected through a screw thread with cutter head, and it is opposite with blade direction of rotation that the screw thread screws direction.Existing alloy
Bar knife is usually to meet global formation, it will usually use integrated setting, then when tool bit abrasion, integrated cutter head just needs
Setting, the secondary operation difficult forming of blade part are replaced, therefore causes the serious waste of blade.If blade turns clockwise,
Screw thread with cutter head cooperation is left-handed, because when blade turns clockwise, cutter head relative counterclockwise rotation, for left hand thread, knife
Head is counterclockwise, and precession is gone, therefore the more can revolve the more tight, reaches identical effect with integrally formed cutter.Blade is repeatable
It uses, achievees the purpose that reduce cost.
Further, the cutter head is additionally provided with dismounting seat.The dismounting sitting toilet provides impetus when replacing cutter head.
Further, the bit interface is coated with titanium nitride coating.Titanium nitride is high with fusing point, hardness is big, chemical stabilization
Property it is good, with the small structural material of wetting of metal and there is higher electric conductivity and superconductivity, can be applied to high-temperature structural material
And superconductor, enable to the increase of cutter grinding number not change cutter molded line.
Further, carbon nano tube/polymer composites reparation is used when the blade internal thread hole abrasion.After abrasion
When blade coordinates with cutter head, it is be easy to cause the quasi- heart offset of cutter head, influences the accuracy of manufacture, it is therefore desirable to the stripped thread of blade internal thread hole
It is repaired, repair materials need not only with the intensity and hardness required by metal, but also with the deformability not available for metal.
It is preferred that Soret carbon nano tube/polymer composites reparation.
Compared with prior art, the present invention having the following advantages and advantages：
1, a kind of removable alloy bar knife of the present invention is removable structure by the way that blade and cutter head is arranged, reduces
The cost of alloy bar knife；
2, a kind of removable alloy bar knife of the present invention screws setting by internal thread, and coating is arranged to cutter head
Improve the using effect of cutter and the abrasion recovery scenario of internal thread, achievees the effect that extension uses birthday noodle；
3, a kind of removable alloy bar knife of the present invention, have the characteristics that it is highly practical, effectively reduce cost.
Description of the drawings
Attached drawing described herein is used for providing further understanding the embodiment of the present invention, constitutes one of the application
Point, do not constitute the restriction to the embodiment of the present invention.In the accompanying drawings：
Fig. 1 is the structural schematic diagram of an embodiment of the present invention；
Fig. 2 is the structural schematic diagram of the cutter head of an embodiment of the present invention.
Label and corresponding component names in attached drawing：
1- alloy bar knives, 2- blades, 3- cutter heads, 4- dismantle seat, 5- screw threads.
Specific implementation mode
To make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiment and attached drawing, to this
Invention is described in further detail, and exemplary embodiment of the invention and its explanation are only used for explaining the present invention, do not make
For limitation of the invention.
Embodiment 1
As shown in Figs. 1-2, a kind of removable alloy bar knife 1 of the present invention, including alloy bar knife 1, the alloy bar
Expect that blade 2 and the cutter head 3 of knife 1 are removable assembling structure, blade 2 is connect with cutter head 3 by screw thread 5, the screw thread 5 screw direction and
2 direction of rotation of blade is opposite.Existing alloy bar knife 1 is usually to meet global formation, it will usually integrated setting is used,
When cutter head 3 is worn again, integrated cutter head 3 just needs to replace setting, the secondary operation difficult forming of 2 part of blade, therefore makes
At 2 serious waste of blade.It is left-handed with the screw thread 5 that cutter head 3 coordinates if blade 2 turns clockwise, because blade 2 turns clockwise
When, the rotation of 3 relative counterclockwise of cutter head, for left hand thread 5, cutter head 3 is that precession counterclockwise is gone, therefore the more can revolve the more tight,
Reach identical effect with integrally formed cutter.Blade 2 is reusable, achievees the purpose that reduce cost.
Embodiment 2
The present embodiment is made that restriction further below on the basis of embodiment 1：The cutter head 3 is additionally provided with dismounting seat
4.The dismounting seat 4 provides impetus convenient for replacing when cutter head 3.3 surface of the cutter head is coated with titanium nitride coating.Titanium nitride has
Fusing point height, the structural material that hardness is big, chemical stability is good, small with the wetting of metal simultaneously have higher electric conductivity and superconduction
Property, high-temperature structural material and superconductor are can be applied to, the increase of cutter grinding number is enabled to not change cutter molded line.
Carbon nano tube/polymer composites reparation is used when 2 internal thread of the blade, 5 hole is worn.Blade 2 after abrasion coordinates with cutter head 3
When, it is be easy to cause the offset of the 3 quasi- heart of cutter head, influences the accuracy of manufacture, it is therefore desirable to which the stripped thread in 2 internal thread of blade, 5 hole is repaired, and is repaiied
Multiple material needs not only with the intensity and hardness required by metal, but also with the deformability not available for metal.It is preferred that Soret carbon
Nano-polymer composite material reparation.
Above-described specific implementation mode has carried out further the purpose of the present invention, technical solution and advantageous effect
It is described in detail, it should be understood that the foregoing is merely the specific implementation mode of the present invention, is not intended to limit the present invention
Protection domain, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should all include
Within protection scope of the present invention.
