Accompanying drawing has accompanying drawing three width of cloth, wherein:
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is blade clearance adjusting device structural representations of the present utility model.
Accompanying drawing 3 is cutting edge locking device structure schematic diagrames of the present utility model.
In the accompanying drawing: 1. rotary drum, 6 crossbeams, 7 left frames, 8 left synchromesh gears, 9 planetary reducers, 10 hydraulic motors, 11 external thread sleeves, 12 inner screw sheaths, 14 times rotary drums of 13 locking devices, 15 locking cylinders, 16 butterfly springs, 17 piston rods, 18T type piece, 19 clamping blocks, 20 cutting edges, 21 cutting edges on base, 2 final drive shafts, 3 right synchromesh gears, the 4 right frames, 5.
The specific embodiment
The utility model is applicable on the hot-rolled strip production line crop flying shear before the finishing mill after the Coil Box.Flying shear frame 4,13 and base 1 are weldment, by upper and lower crossbeam 6 left and right frame are linked together, and frame is fixed on the base 1 by attachment bolt.Rotary drum 5,14 rolling bearings by its two ends are installed in the dead eye of frame 4,13 up and down, form an integral body with frame, are equipped with all on the every rotary drum that the relative phase angular difference is 90 degree between 19,21, two cutting edges 19,21 of two cutting edges.Crop flying shear is driven by dc main motor, and final drive shaft 2 drives rotary drum 14 down, drives by synchromesh gear 3,8 again and goes up rotary drum 5, makes up and down rotary drum have identical rotating speed and finishes shear action.The blade clearance adjustment of the crop flying shear of present embodiment is to drive a double thread by hydraulic motor 10 by planetary reducer 9 to pay 11,12 and rotate, and makes rotary drum 5 along the mobile realization of axis generation maximum ± 15mm.Screw thread is paid by being loaded on forming with the inner screw sheath 12 that is fixed on the frame with the close-connected external thread sleeve 11 of last rotary drum axle of rotary drum axial end, because frame is fixed, therefore pay when under planetary reducer 9 drives, rotating when screw thread, external thread sleeve 11 limit spinning side bands are moving go up rotary drum axially move (maximum is ± 15mm).Because up and down the synchromesh gear of rotary drum axle head dress is a helical teeth, the axially movable result of last rotary drum must make rotary drum up and down relatively rotate and reach the purpose of adjustment blade clearance.The driving of hydraulic motor realizes by movable Hydraulic Station lashup high-pressure hose, so the adjustment of blade clearance is online can carry out, and is very convenient quick.Fixedly realizing of each cutting edge of the crop flying shear of present embodiment by seven locking cylinders, the center line of locking cylinder 15 and cutting edge plane are the angle of 7 degree, the T type piece 18 of disk spring 16 tension piston rods 17 ends in the locking cylinder, tension directly is stuck in the clamping block 19 of cutting edge side again.Because the center line of locking cylinder and cutting edge plane are the angle of 7 degree, during the clamping block 19 of T type piece tension cutting edge side, fix cutting edge firmly as same wedge.The coupling mechanism force of the nearly 82kN of each locking cylinder groups of springs.When needs dismounting cutting edge, feeding pressure oil in the locking cylinder of locking device makes piston compress disk spring, with clamping block jack-up, owing to exist the front to mention 7 degree angles, locking can be removed in the gap that makes clamping block and cutting edge side produce about 1.5mm by piston rod.
