The utility model discloses an install the blade on the knife rest to the elastic deformation gap of blade is utilized, when knife rest and blade machining precision are general, assembly requirements convenient, accurate, reliable fast can be satisfied, can be when the shearing force be bigger, the reliable and stable preimpregnation silk bundle of cutting still, simple structure uses reliably, and low cost has the significance to the first structural design of fiber placement.
Description
Technical field
This utility model relates to a kind of cutting mechanism, is specifically related to a kind of carbon fibre initial rinse tow cutting mechanism.
Background technology
Owing to the high specific strength of composite, corrosion resistance etc. are better than the performance of traditional material, it is in field application such as Aero-Space
More and more extensive.One important automatic forming equipment of carbon fibre initial rinse tow is automatic fibers layer, and placement head is piddler
Critical component in machine, in laid course, needs to cut preimpregnation tow in placement head according to different laying tracks
Disconnected.
It is not specifically designed to the ready-made cutter shearing carbon fibre initial rinse tow at present, typically uses the combination assembling of blade, knife rest,
Operation is cut off utilizing Telescopic-cylinder to complete.
Owing to the shearing force that carbon fibre initial rinse tow modulus is big, hardness is high, need is big, unless machining accuracy is high, the most commonly
Cutter is low due to the assembly precision of blade and knife rest, there is gap, and the degree of freedom of blade is not by Complete Bind, when shearing,
Blade easily loosens, and after the most repeatedly shearing, the reliability cut off is substantially reduced.
Utility model content
For overcoming the problems of the prior art, the purpose of this utility model is providing a kind of carbon fibre initial rinse tow cutting mechanism, should
Cutting mechanism is capable of the quick assembling of cutter, and reliable and stable cuts off carbon fibre initial rinse tow.
For achieving the above object, this utility model adopts the following technical scheme that:
A kind of carbon fibre initial rinse tow cutting mechanism, including knife rest, knife rest end offers locating slot, installs cutter in locating slot
Sheet, and blade is fixed by screws on knife rest, and between screw and blade, it is provided with spring shim；Described locating slot sets
Knuckle, blade end is had to be provided with the fillet matched with knuckle.
The thickness of described blade is 0.5mm to 2mm.
Described blade and knife rest use interference fit.
Described blade end offers gap along blade lengths direction.
Screwed hole is offered on described knife rest.
It is reserved with via on described blade.
Compared with prior art, this utility model have the advantages that this utility model by blade is arranged on knife rest,
And can move up and down with knife rest, when knife rest and blade machining accuracy are general, rapid and convenient, precision, reliable can be met
Matching requirements, can be when shearing force be bigger, the most reliable and the most stable cuts off preimpregnation tow, simple in construction, and use can
Lean on, with low cost, piddler header structure is designed with significance, overcomes and prior art utilizes Telescopic-cylinder complete to cut off behaviour
When making, the complicated insecure problem of mechanism.This utility model simple in construction, is that the carbon fibre initial rinse tow that reliability is the highest is sheared
Mechanism, and can be easy to use with rapid and convenient, critically assemble.
Further, in this utility model, blade end offers gap, and knife rest has the locating slot with blades fit, to cutter
When inserting blade in frame, blade can produce the deformation of trace, convenient for assembly, inserts after entering, and blade both sides and knife rest are tight
Coordinate, then be screwed, simple and reliable for structure, easy for installation.
Further, by arranging spring shim between screw and blade, locking effect is played.
Accompanying drawing explanation
Fig. 1 is blast installation diagram of the present utility model.
Fig. 2 is the profile of cutting mechanism.
In figure, 1 is knife rest, and 2 is spring shim, and 3 is screw, and 4 is blade.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
Seeing Fig. 1, this utility model includes that knife rest 1, knife rest 1 end offer locating slot, and being provided with in locating slot can be upper and lower
The blade 4 of movement, and blade 4 is arranged on knife rest 1 by screw 3, and it is provided with spring shim between screw 3 and blade 4
2。
Described locating slot is provided with knuckle, and blade 4 end is provided with the fillet matched with knuckle.
The thickness of described blade 4 is 0.5mm to 2mm, and blade 4 and knife rest 4 use interference fit, and blade 4 end is along blade lengths
Direction offers and is reserved with via on gap, and blade 4.
Screwed hole is offered on described knife rest 1.
When the machining accuracy of blade and knife rest is general, in order to eliminate the assemblage gap of cutter, it is to avoid be likely to occur during use
Loosen, improve assembling convenience, this utility model provide a kind of high reliability, high accuracy assembling carbon fibre initial rinse tow
Cutting mechanism, this cutting mechanism makes cutter and knife rest to closely cooperate, and eliminates and is subject to during using during bigger shearing force to hold
Be easily generated loosens, and improves service life and the reliability of cutting mechanism.
Blade uses the pole ultra micron diamond tungsten steel blade of highly abrasion-resistant, and its rigidity is high, is unlikely to deform, in the blade other end
Between crack；Having the locating slot with blades fit on knife rest, when inserting blade in knife rest, blade can produce the change of trace
Shape, convenient for assembly, insert after entering, blade both sides and knife rest closely cooperate, then are screwed, simple and reliable for structure, peace
Dress is convenient.
According to an embodiment of the present utility model, the cutting edge angle of inclination of blade can change between 45 ° and 90 °.
Knife rest 1 and blade 4 utilize screw 3, spring shim 2 to be attached fixing.When assembling, blade 4 is inserted into knife rest 1
In locating slot, in order to ensure that knife rest 1 and blade 4 fit tightly, very close to each other, both assemble employing interference fit, ordinary circumstance
Under, using interference fit, blade inserts locating slot can be relatively difficult, and on blade 4, one end has gap, when assembling, by
In the existence in gap, 4 liang of lateral centres of blade are easier deformation, and this small deflection makes blade 4 can be readily intercalated into cutter
After locating slot on frame 1, and insertion, both coordinate closely, and locating slot limits the left and right translation of blade.
Seeing Fig. 2, after blade 4 inserts knife rest 1, utilize screw 3, spring shim 2 to fix blade 4, blade 4 is in all directions
Degree of freedom played locking effect by Complete Bind, spring shim 2.
This utility model offer is a kind of can Fast Installation, precision-fit, reliable and stable carbon fibre initial rinse tow cutting mechanism.
Its tool holder designs has locating slot, and in the middle of handle of a knife one end of blade, elastic deformation gap during reserved assembling, utilizes the small change of blade
Shape so that blade and knife rest reach Fine Boring, recycling screw and spring shim connect fixing, afterwards long-time use or
Will not produce the problem that blade loosens during the bigger shearing force of person, reliable and stable cuts off carbon fibre initial rinse tow.
