A kind of Rack hydraulic cylinder straightener as depicted in figs. 1 and 2, comprise frame 1 and be laid in the hydraulic cylinder 2 in frame 1 along frame 1 length direction, the outer end of described hydraulic cylinder 2 piston rod 2-1 is connected with frame 1, the other end of described hydraulic cylinder 2 is connected with frame 1 by fairlead 5, the upper surface of described hydraulic cylinder 2 cylinder barrel is provided with the upper rack 14 laid along hydraulic cylinder 2 length direction, the lower surface of described hydraulic cylinder 2 cylinder barrel is provided with the lower tooth bar 15 laid along hydraulic cylinder 2 length direction, multiple 4 and multiple lower gear 8 of cogging is provided with in described frame 1, cog described in multiple and 4 be all positioned at the top of hydraulic cylinder 2 and be all meshed with upper rack 14, multiple described lower gear 8 is all positioned at the below of hydraulic cylinder 2 and is all meshed with lower tooth bar 15, the arranged outside of described frame 1 has multiple eccentric smoothing roll 3 and multiple lower eccentric smoothing roll 9, multiple described eccentric smoothing roll 3 with multiple described in cog 4 central shaft connect one to one, multiple described lower eccentric smoothing roll 9 connects one to one with the central shaft of multiple described lower gear 8, multiple described eccentric smoothing rolls 3 lay respectively at the top of eccentric smoothing roll 9 center line line under adjacent two, the line of multiple described eccentric smoothing roll 3 center line parallels with the line of multiple described lower eccentric smoothing roll 9 center line.In the present embodiment, multiple described eccentric smoothing roll 3 is equidistantly laid, and multiple described lower eccentric smoothing roll 9 is equidistantly laid, and the axis of each eccentric smoothing roll 3 is on the perpendicular bisector of eccentric smoothing roll 9 axis line under adjacent two.
As shown in Figure 3, this Rack hydraulic cylinder straightener also comprises control system, described control system comprises the depress switch 10 for detecting upper eccentric smoothing roll 3 and lower eccentric smoothing roll 9 drafts, for detecting the trip switch 11 of upper eccentric smoothing roll 3 and lower eccentric smoothing roll 9 amount of unclamping and the controller 17 for receiving described drafts signal and the described amount of unclamping signal, the input of described controller 17 is connected with depress switch 10 and trip switch 11, the output of described controller 17 is connected to solenoid directional control valve 18, described solenoid directional control valve 18 is connected with hydraulic cylinder 2 rod chamber and rodless cavity, described hydraulic cylinder 2 cylinder barrel is provided with the sensing chip 12 matched with depress switch 10 and trip switch 11 away from one end of fairlead 5, described depress switch 10 and trip switch 11 are all arranged in frame 1.In the present embodiment, described depress switch 10 and trip switch 11 are Hall switch, and described sensing chip 12 is made of metal.
During use, when the rod chamber of hydraulic cylinder 2 and rodless cavity replace oil-feed and oil extraction, the cylinder barrel of hydraulic cylinder 2 replaces side-to-side movement, driven by upper rack 14 and cog 4, drive lower gear 8 by lower tooth bar 15, described in cog and 4 synchronously drive upper eccentric smoothing rolls 3 to rotate, described lower gear 8 synchronously drives lower eccentric smoothing roll 9 to rotate, the size of vertical range h between eccentric smoothing roll 3 lower edge and lower eccentric smoothing roll 9 upper limb in change, thus pressure aligning is carried out to goods 16 and unclamps.
In the present embodiment, the reference for installation of this Rack hydraulic cylinder straightener is extremely important, when hydraulic cylinder 2 is in the point midway of its stroke, by the equal level of eccentric direction of upper eccentric smoothing roll 3 and lower eccentric smoothing roll 9 towards a left side, the vertical range of the upper limb of upper eccentric smoothing roll 3 lower edge and lower eccentric smoothing roll 9 is h, the gear centre eccentric throw that each eccentric smoothing roll 3 is connected relative to self with the center of each lower eccentric smoothing roll 9 is a, its minimum drafts is (h-2a) like this, and the maximum amount of unclamping is (h+2a).The pass of the maximum gauge t of goods 16 and drafts and the amount of unclamping is: (h-2a) < t < (h+2a).Because trip switch 11 and the distance of depress switch 10 are S, directly control the amount of unclamping.The size of the amount of unclamping and the original curved degree of goods 16, elasticity, stress state are relevant, grasp flexibly in practice, are greater than original curved value for principle with the amount of unclamping.
In the present embodiment, the pressure of this Rack hydraulic cylinder straightener, aligning action are controlled by control system, when control system controls solenoid directional control valve 18, make the rodless cavity oil-feed of hydraulic cylinder 2, hydraulic cylinder 2 cylinder barrel moves right, and upper rack 14 is rotated counterclockwise by smoothing roll 3 eccentric in 4 drives that cog, and descends tooth bar 15 to drive lower eccentric smoothing roll 9 to rotate clockwise by lower gear 8 simultaneously, now h value reduces, and is depressed by goods 16.Goods 16 are pushed ahead under the effect of external force, upper eccentric smoothing roll 3 and the rotation simultaneously of lower eccentric smoothing roll 9, realize the pressure to goods 16 and aligning action, when depress switch 10 senses sensing chip 12, controller 17 obtains the drafts of upper eccentric smoothing roll 3 and lower eccentric smoothing roll 9, and control solenoid directional control valve 18 and switch, this Rack hydraulic cylinder straightener performs unclamps action, the i.e. rod chamber oil-feed of hydraulic cylinder 2, hydraulic cylinder 2 cylinder barrel is to left movement, upper rack 14 is rotated clockwise by smoothing roll 3 eccentric in 4 drives that cog, descend tooth bar 15 to drive lower eccentric smoothing roll 9 to rotate counterclockwise by lower gear 8 simultaneously, now h value increases, goods 16 are unclamped, when trip switch 11 senses sensing chip 12, controller 17 obtains the amount of unclamping of upper eccentric smoothing roll 3 and lower eccentric smoothing roll 9, controller 17 is performed again by switching solenoid directional control valve 18 and depresses next time, aligning action.In the present embodiment, this Rack hydraulic cylinder straightener overcome traditional five-roll machine aligning center not conllinear, aligning center line depart from, adjust the shortcomings such as complexity, flattening precision is high; Solution must not be nipped " gooseneck boom is curved " goods problem fast, is particularly useful on high-speed automated production line, and adjustment maintenance capacity decreases 80%, and productivity ratio improves 6% ~ 10%, and automatization level is high.
As shown in Figure 1, the gag lever post 6 that level is laid is provided with in described fairlead 5.Described gag lever post 6 is threaded with frame 1, and is fixed by nut 7.By the change in location of gag lever post 6, the spacing distance that can adjust hydraulic cylinder 2 is S1.For the goods 16 of each specification, first the position of gag lever post 6 is determined, then determine S1 according to the original curved degree of goods 16, now demarcate the position (switch sender is as the criterion) of trip switch 11, determine the position (switch sender is as the criterion) of depress switch 10 afterwards again.Now the pass of S and S1 is: S < S1.First slow down when ensureing that hydraulic cylinder 2 is depressed, finally reach pinpoint object.
As shown in Figure 1, described piston rod 2-1 is articulated and connected by bearing pin 13 and frame 1.The quantity of described eccentric smoothing roll 3 is two, and the quantity of described lower eccentric smoothing roll 9 is three.The structure of multiple described eccentric smoothing roll 3, multiple described lower eccentric smoothing roll 9 is all identical with size.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every above embodiment is done according to the technology of the present invention essence any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solution of the present invention.
