The utility model adopts following technical scheme: the hinge means of bender comprises the connecting plate, front rod, back link, middle connecting rod, " Off " shape part and the bending oil cylinder that are connected in bender bending crossbeam bottom; The widthwise edge of this connecting plate, middle connecting rod and " Off " shape part is parallel to each other and from top to bottom be arranged in order, and this front rod, back link are parallel to each other; The rearward end of the rearward end of connecting rod and " Off " shape part widthwise edge is articulated on the frame of bender in being somebody's turn to do, the upper, middle and lower portion of this front rod is articulated in the leading section of connecting plate, middle connecting rod, " Off " shape part widthwise edge respectively, and the upper, middle and lower portion of this back link is articulated in the middle part of the rearward end of connecting plate, middle connecting rod, the middle part of " Off " shape part widthwise edge respectively; Be somebody's turn to do the bottom on the oblique limit of " Off " shape part and the piston rod of bending oil cylinder and articulate, the cylinder body of this bending oil cylinder is hubbed on the frame of bender.
The hinge means of aforementioned bender, wherein all bendings downwards of the middle part of the widthwise edge of connecting rod, " Off " shape part, the middle part of described back link, bottom are articulated in the knuckle place, middle part of middle connecting rod, " Off " shape part widthwise edge respectively.
The hinge means of aforementioned bender, its each articulated section adopts bearing pin to be connected with pin-and-hole, is provided with polytetrafluoroethylene bushing between bearing pin and the pin-and-hole.
By above-mentioned description to the utility model structure as can be known, compare, the utlity model has following advantage with prior art: one, the bending angular range is big, can go out arbitrarily angled 0 ° of-132 ° of scope invagination; Two, in change bending angle process, need not more mold exchange, very easy to use; Three, because this hinge means has nine transmissions, i.e. nine transmission forces, each transmission force is stressed less, is difficult for deforming, so Stability Analysis of Structures, and the bending precision height; Four, the polytetrafluoroethylene bushing of bearing pin has guaranteed the transmission accuracy and the wearability of hinge; Five, whole hinge means is installed on the side of frame, and assembling and debugging are convenient.

The specific embodiment
Below with reference to Fig. 1 to Fig. 3 the specific embodiment of the present utility model is described.
With reference to Fig. 1, be the side-looking structure of the bender that adopts this hinge means.This bender primary structure comprises frame 10, double wall 20, entablature 301, sill 302, bending crossbeam 40 and hinge means 1.Double wall 20 postmedians are hubbed on the frame 10, leading section is fixedlyed connected with entablature 301, rearward end is hubbed on the piston rod of clamping cylinder 201, can make entablature 301 and the sill 302 that is fixed on the frame 10 will treat that together the sheet material of bending clamps during oil cylinder 201 actions.And hinge means 1 can make bending crossbeam 40 upset, so that be clamped to sheet material between entablature 301, the sill 302 by bending.
Referring to figs. 1 through Fig. 3, this hinge means 1 comprises connecting plate 11, front rod 14, back link 15, middle connecting rod 12, " Off " shape part 13 and the bending oil cylinder 16 that is connected in bender bending crossbeam 40 bottoms simultaneously.The widthwise edge 131 of this connecting plate 11, middle connecting rod 12 and " Off " shape part 13 is parallel to each other and from top to bottom be arranged in order, and this front rod 14, back link 15 are parallel to each other.The rearward end of the rearward end of connecting rod 12 and " Off " shape part 13 widthwise edges 131 is articulated on the frame 10 of bender in being somebody's turn to do, the upper, middle and lower portion of this front rod 14 is articulated in the leading section of connecting plate 11, middle connecting rod 12, " Off " shape part 13 widthwise edges 131 respectively, and the upper, middle and lower portion of this back link 15 is articulated in the rearward end of connecting plate 11, the middle part of middle connecting rod 12, the middle part of " Off " shape part widthwise edge 13 respectively.Be somebody's turn to do the bottom on " Off " shape part 13 oblique limits 132 and the piston rod of bending oil cylinder 16 and articulate, the cylinder body of this bending oil cylinder 16 is hubbed on the frame 10 of bender.The middle part of the widthwise edge 131 of middle connecting rod 12, " Off " shape part 13 is bending slightly downwards all, and the middle part of described back link 15, bottom are articulated in the knuckle place, middle part of middle connecting rod 12, " Off " shape part 13 widthwise edges 131 respectively.
