Among the figure: 1 is frame, and 2 is fixed rotating shaft, and 3 is lower gear, 4 for cogging, and 5 for adjusting rotating shaft, and 6 is eccentric bushing, 7 is end cap, and 8 is adjusting lever, and 9 is guiding mechanism, 10 is gear, and 11 is tooth bar, and 12 are the compression spring, 13 is manual nut, and 14 is oil cylinder or driving mechanisms such as cylinder or electric cylinder, and 15 is groove, 16 is fork, and 17 is slide bar.
The specific embodiment
The present invention is mainly by frame 1, place on the frame 1 cog 4 the adjustment rotating shaft 5 of the fixed rotating shaft 2 of band lower gear 3 and band, be sheathed on the eccentric bushing of adjusting in the rotating shaft 56, place on the frame 1 adjusting lever 8 with eccentric bushing 6 mutually related guiding mechanisms 9, place end cap 7 formations such as grade at eccentric bushing 6 axial two ends; The bearing saddle bore concentric at eccentric bushing 6 two ends and have the eccentric throw of 1～10mm with the cylindrical of eccentric bushing.
Concrete enforcement of the present invention is as follows:
Shown in attached Fig. 1 and 2, when the sheet material thickness of slab increases, need to increase the gap between two rotating shafts up and down, during adjustment, adjusting lever 8 moves up, and eccentric bushing 6 is rotated counterclockwise, because the existence of eccentric distance e, adjust rotating shaft 5 and move up, the distance A that fixed rotating shaft 2 and adjustment rotating shaft are 5 increases, thereby the gap of realizing roll shop building increases.
When the sheet material thickness of slab reduces, need reduce the gap between two rotating shafts up and down, promptly reduce the A size, during adjustment, adjust screw rod 7 and move down, eccentric bushing 6 is turned clockwise, because the existence of eccentric distance e, adjust rotating shaft 5 and move down, the distance A that following fixed rotating shaft 2 and adjustment rotating shaft are 5 reduces, thereby the gap of realizing roll shop building reduces.
After adjusting as stated above, owing to have self-locking property between adjusting lever 8 and the eccentric bushing 6, so the radial load of roll in forming process can not cause the variation of distance between axles size A.
Although can make things convenient for, finish reliably eccentric throw by preceding described application the technology of the present invention regulates and is applied in the actual production, but the invention is not restricted to this, accompanying drawing 3～Fig. 7 has listed the replaceable structure of a series of guiding mechanisms of the present invention, adjusting lever 8, eccentric bushing 6.
In the accompanying drawing 3, distance between axles eccentric wheel guiding mechanism is positioned at the bottom of fixed rotating shaft 2, can cross the adjustment rotating shaft 5 below adjusting, and realizes adjusting the spacing A that goes up between lower rotary shaft.
In the accompanying drawing 4, adjust part and change the rack-and-pinion transmission into, be arranged with compression spring 12 on the corresponding adjusting lever 8, adjustment nut 13 can spur tooth bar 11 and move up and down, the gear 10 that tooth bar 11 drives on the eccentric bushing, make the eccentric bushing rotation, thereby adjust moving up and down of rotating shaft 5, realize adjusting the spacing A that goes up between lower rotary shaft
In the accompanying drawing 5, adjusting part still is the rack-and-pinion transmission, and the same Fig. 4 of the operation principle of adjustment carries out the parts input but guiding mechanism is changed into by the manual adjustments nut, and it carries out parts is driving mechanisms 14 such as oil cylinder, cylinder or electric cylinder;
In the accompanying drawing 6, fork 16 is installed in the slide bar 17, is embedded in again in the groove of eccentric bushing 15, when slide bar 17 being slided up and down by adjusting nut 13, fork 16 is stirred eccentric bushing 15 rotations, adjusts moving up and down of rotating shaft 5 from face, realizes adjusting the spacing A that goes up between lower rotary shaft;
In the accompanying drawing 7, the same Fig. 6 of the operation principle of adjustment carries out the parts input but guiding mechanism is changed into by the manual adjustments nut, and it carries out parts is driving mechanisms such as oil cylinder, cylinder or electric cylinder.
