In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of shockproof knife bar one of the present utility model preferred embodiment;
Fig. 2 is shockproof knife bar one preferred embodiment front view of the present utility model.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of shockproof knife bar, comprise: cutter bar body 1, shock-proof block 2, edge bearing 3 and blade locating piece 4, described cutter bar body 1 comprises the first side 11 be connected successively, second side 12 and the 3rd side 13, described first side 11 is provided with the first groove 14, described shock-proof block 2 is connected in described first groove 14, described second side 12 is provided with a cell body, described cell body is arranged to the square of correspondence according to folded blade shapes, an acute angle is arranged in central axis and described first side 11 of described cell body, described edge bearing 3 is fixedly connected in described cell body, described blade locating piece 4 is fixedly connected on described second side 12, a space for fixturing blade is formed between described edge bearing 3 and described blade locating piece 4, described shock-proof block 2 is different from described cutter bar body 1 material.Described edge bearing 3 is fixedly connected in described cell body, an acute angle is arranged in central axis and described first side 11 of described cell body, certainly, according to the needs of actual production, an obtuse angle or right angle also can be arranged in central axis and described first side 11 of described cell body, in other words, the tool cutting edge angle of knife bar can be arranged to acute angle, right angle or obtuse angle, blade clamping is between described edge bearing 3 and described blade locating piece 4, the use side of such blade and knife bar have certain angle, and this angle is acute angle, the operation being convenient to blade uses.Described cutter bar body 1 is made by tool steel, shock-proof block 2 is the metal of block tin or other materials, because cutter bar body 1 is different with the material of shock-proof block 2, blade operationally, its vibration frequency is different, thus can not resonance be formed, effectively reduce Oscillation Amplitude during blade work, shockproof effect is good.
In addition, described cutter bar body 1 is divided into the first supporting surface and the second supporting surface 15 by described cell body, and described second supporting surface 15 is arranged to an acute angle with described 3rd side 13.Blade clamping is used for fixturing blade in the space that the first supporting surface, the second supporting surface 15, edge bearing 3 and blade locating piece 4 are formed, fixed blade.
In addition, described second side 12 is provided with second groove 16, and described second groove 16 parallels with described 3rd side 13, and one end of described second groove 16 is arranged on the second supporting surface 15.This is due to the existence of the second groove 16, and the second supporting surface 15 elastic deformation increases, thus during installation and removal blade, ensures the convenience that blade is installed.
In addition, described 3rd side 13 is provided with a housing pin 5, and described housing pin 5 is connected on described 3rd side 13 and the second groove 16.Can be finely tuned the distance of the 3rd side 13 and the second groove 16 by housing pin 5 like this, make the installation and removal of blade more convenient, fast.
In addition, the bottom of described first supporting surface and described second supporting surface 15 is all provided with a rounding 17.Rounding 17 leaves certain space between the bottom of blade and cell body under can ensureing that blade in working order, can not hurt blade in blade work process, particularly has protruding blade for end, can effectively protect blade not to be worn.
In addition, described shockproof knife bar also comprises cover plate 6, and described cover plate 6 is positioned at the top of described shock-proof block 2, and is connected on described first groove 14.Cover plate 6 covers above shock-proof block 2, is then fixedly connected on the first groove 14, and outward appearance is consistent on the whole can to ensure cutter bar body 1, makes it simply attractive in appearance.
In addition, described second side 12 is also provided with the 3rd groove 18, described 3rd groove 18 matches with the bottom of described blade locating piece 4.3rd groove 18 can effectively prevent blade locating piece 4 from shaking in the process of blade work, thus protection blade reduces the wearing and tearing of blade, extends the service life of blade.
In addition, described shockproof knife bar also comprises spring, and described second side 12 is provided with one for placing the blind hole of spring, and described spring is connected between described blade locating piece 4 and blind hole.Spring can ensure that blade locating piece 4 and the second side 12 have certain active force and distance, when mounting and dismounting blade, blade can give spring active force, make spring suitably elongated, to increase the distance of blade locating piece 4 and the second side 12, thus reach the distance increasing blade locating piece 4 and edge bearing 3, and blade in working order under, spring is under the effect of its own resilient, the distance of tension blade locating piece 4 and the second side 12, thus ensure that blade locating piece 4 is less with the distance of edge bearing 3, can not shake when ensureing blade work, reduce the wearing and tearing of blade, improve the stability of blade work state, extend the service life of blade and shockproof knife bar.
In addition, described shock-proof block 2 is 2-4:5 with the Thickness Ratio of described cutter bar body 1, namely ensures that whole shockproof knife bar has good shockproof function, the holistic cost of the shockproof knife bar of increase not too high again.
Be different from prior art, the shockproof lever structure of the utility model is simple, blade easy installation and removal quick, Oscillation Amplitude when effectively reducing blade work, the wearing and tearing of good, the effective reduction knife bar of shockproof effect, the service life extending knife bar, good stability, result of use be better.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
