The specific embodiment
Existing extruder shear adopts piston oil-cylinder to drive the structure of a rimmer knife bar, because shear will be subjected to the effect of eccentric force when shearing, can form a bigger moment of flexure on knife bar.Knife bar has enough rigidity and stability in order to guarantee to shear, knife bar also must be provided with guiding mechanism, and along with the growth of scissors stroke, guiding length can be at double increase, this makes that the overall dimensions phase strain of shear device of extruder is big, the installation of extruder, uses and keeps in repair all and produced a lot of problems because of such height.
The embodiment of the invention provides a solution, and its basic thought is: piston and piston rod are fixed, and cylinder body moves reciprocatingly.
Understand technical scheme of the present invention for those skilled in the art can be known, technical scheme of the present invention is described in detail below in conjunction with drawings and Examples.
See also Fig. 1, a kind of shear device of extruder installation diagram that Fig. 1 provides for the embodiment of the invention, wherein 1 is piston rod, and 2 is disk, and 3 is column, and 4 is cylinder body, 5 is the scissors seat.
Piston rod 1 is fixed on the frame by disk 2 and column 3, and its central post 3 is a studs, and scissors seat 5 links to each other with frame, works to support whole shear device.Cylinder body and piston are formed a hydraulic means, are the major parts of control shear motion.
See also Fig. 2, a kind of shear device of extruder cut-away view that Fig. 2 provides for the embodiment of the invention, wherein 1 is piston rod, 2 is disk, 3 is column, and 4 is cylinder body, and 5 is the scissors seat, and 6 is fairlead, 7 is piston, and 8 is frame, and 9 is blade, and 10 and 11 is two hydraulic fluid ports.Wherein the piston rod 1 among piston rod 1, disk 2, column 3, cylinder body 4, scissors seat 5 and Fig. 1, disk 2, column 3, cylinder body 4 and scissors seat 5 are same parts, and function is all identical with annexation, repeats no more.
See also Fig. 3 A and Fig. 3 B, Fig. 3 A and Fig. 3 B are embodiment of the invention hydraulic cylinder principle of optimality figure, and wherein 1 is piston rod, and 2 is cylinder body, and 3 is blade, and 4 is piston.Among A figure and the B figure, left side hydraulic cylinder schematic diagram is the shear device of extruder that generally uses in the prior art, and right side schematic diagram is the shear device of extruder after the embodiment of the invention is improved.Piston rod position schematic diagram when A figure is shear work, shear need rise to (bump shear when avoiding recipient to draw close die frame) more than the recipient shell peak, piston rod position figure when B figure is the shear inoperative when inoperative.Contrast AB two figure when shear duty and off working state, because the embodiment of the invention adopts fixed piston rod, adopt cylinder body to serve as knife bar, make the height of whole shear device reduce the distance of a stroke.
See also Fig. 4, the another kind of shear device of extruder cut-away view that Fig. 4 provides for the embodiment of the invention.Wherein 1 is piston rod, 2 is disk, 3 is column, 4 is cylinder body, 5 is the scissors seat, 6 is fairlead, 7 is piston, 8 is frame, and 9 is blade, and 10 and 11 is two hydraulic fluid ports, 12 is cutter head, wherein piston rod 1, disk 2, column 3, cylinder body 4, scissors seat 5, fairlead 6, piston 7, frame 8, blade 9, piston rod 1 among hydraulic fluid port 10 and hydraulic fluid port 11 and Fig. 2, disk 2, column 3, cylinder body 4, piston rod 1 among scissors seat 8 and Fig. 1, disk 2, column 3, cylinder body 4, frame 5, fairlead 6, piston 7, scissors seat 8, blade 9, hydraulic fluid port 10 and hydraulic fluid port 11 are same parts, and function is all identical with annexation, repeats no more.
Since cylinder body 4 complex structures, the processing cost height, and in order effectively to protect cylinder body 4, improved shear device has added a cutter head 12 at the cylinder body front end, allows the blade 9 of easy damage separate with cylinder body 4, prolongs the service life of cylinder body.Described cutter head 12 is for being installed on the cylinder body 4, and blade 9 is installed on the cutter head 12.
See also Fig. 5, a kind of shear device of extruder partial sectional view that Fig. 5 provides for the embodiment of the invention, wherein 13 are the guiding feather key.
Circular cylinder body is processed easily, but circular cylinder body rotation phenomenon can occur again in pumping.Because the effect that cylinder body 4 has served as the scissors bar simultaneously has correct position in order to guarantee blade 9 when shearing, such rotation must be avoided.Therefore, improved scissors apparatus has been done guiding feather key 13 devices on cylinder body 4 and fairlead 6, avoid cylinder body to rotate by the positioning action of guiding feather key 13.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
