During specific works, regulate metal wire frame length during bending:
First, oppositely turn all retaining mechanisms, unclamp the locking to rotating mechanism and 4 foldable components, then the handwheel A86 of the rotating mechanism corresponding with length adjustment bar 6 is rotated, thus drive length adjustment bar 6 to rotate, 4 foldable components are made all to move to the center of length adjustment bar 6 or move away from center, the rule between the first foldable component 1 and the second foldable component 2 is observed in rotation process, when meeting the requirements of length dimension, stop operating handwheel A86, tighten the handwheel B94 be connected with rotating mechanism, locking length adjustment bar 6, then the retaining mechanism 9a of the first foldable component 1 is tightened, tighten the retaining mechanism 9b of the second foldable component 2 simultaneously, lock the first foldable component 1 and the second foldable component 2, complete the adjustment to metal wire frame length,
The width of metal wire frame during adjustment bending:
First, rotate the handwheel A86 of the rotating mechanism corresponding with width adjusting bar 5, thus drive width adjusting bar 5 to rotate, the spur gear D32 of the 3rd foldable component 3 and the 4th foldable component 4 is driven to rotate, spur gear D32 drives spur gear E35 to rotate, feed screw nut 30 follows spur gear E35 and rotates, thus realize the 3rd foldable component 3 and the 4th foldable component 4 moves along width adjusting bar 5, in the process of rotating handwheel A86, observe the rule between the 3rd foldable component 3 and the first foldable component 1, and second rule between foldable component 2 and the 4th foldable component 4, when meeting the requirements of width dimensions, stop operating handwheel A86, tighten the handwheel B94 be connected with rotating mechanism, locking rotating mechanism and width adjusting bar 6, tighten the handwheel B94 of the locking device 9c be connected with backstay B11b again, tighten the handwheel B94 of the locking device 9d be connected with backstay C11c, lock the 3rd foldable component 3 and the 4th foldable component 4, complete the adjustment to metal wire width of frame,
In addition, during the metal frame of if desired bending different in width, the spur gear D32 of the 3rd foldable component 3 or the 4th foldable component 4 can be rotated separately, realize the independent adjustment of width;
The length of metal frame is regulated if only need, when not needing the width regulating metal frame, only need to unclamp locking device 9a, locking device 9b and locking device 9f to carry out regulating, because locking device 9c is still locking state to the 3rd foldable component, locking device 9d is still the state of locking to the 4th foldable component 4, so the distance between the first foldable component 1 and the 3rd foldable component 3 keeps fixing, distance between second foldable component 2 and the 4th foldable component 4 keeps fixing, namely in the process of adjustment bending frame length, keeps the width of bending frame constant.3rd foldable component, the 4th foldable component and the first foldable component, the second foldable component are fixed by different backstays by the utility model respectively, simplify regulating step, save regulating time.
Regulate bending angle:
First, rotate handwheel C71, bevel gear A21 is driven to rotate, thus drive bevel gear B22 successively, splined shaft A24, spur gear A25, spur gear B26 and splined nut B28 rotates, because the axle 101 of splined nut B28 and its inside is threaded connection, therefore handwheel C71 is rotated, the link position of splined nut B28 and axle 101 is finally made to move up and down, moving up and down of the telescopic band carry-over bar 29 of hydraulic jack A, the link position of splined nut B28 and axle 101 moves up and down, it is in fact the stroke changing tooth bar 29, thus change spur gear C104, the rotational angle of cam 106 and folded block 108.Due to angular adjustment bar 7 having installed diameter dial gauge 72 additional, only need to rotate handwheel C71, made the pointer of diameter dial gauge 72 point to corresponding diameters;
After having carried out the adjustment of above-mentioned bending width, length and angle, carry out bending, first metal wire is put in the plane of the bed die 107 of 4 bending main bodys 10, the axle 103 of hydraulic jack 10c stretches out, compress metal wire, the axle 101 of the hydraulic jack A of the 3rd foldable component 3 and the 4th foldable component 4 shrinks, and drives folded block 108 to rotate, completes the bending at two angles; Then the axle 102 of the hydraulic jack 10b of the 3rd foldable component 3 and the 4th foldable component 4 shrinks, the bed die 107 corresponding with the 3rd foldable component 3 and the bed die 107 corresponding with the 4th foldable component 4 are drawn back to cam 106 plane or cam 106 internal plane, for next step bending provides space; Finally, the axle 101 of the hydraulic jack A of the first foldable component 1 and the second foldable component 2 shrinks, and drives folded block 108 to rotate, completes the bending at two other angle; After 4 whole bendings in angle, the bed die 107 corresponding with the first foldable component 1 and being driven by hydraulic jack 10b with bed die 107 corresponding to the second foldable component 2 is regained, in the retracting device that the metal frame of bending and forming drops below bender.
The present embodiment is bent into rectangular metal frame to be described for example, is if desired bent into other polygon metal frames, only need increase the number of bending main body and foldable component, and the angle of corresponding adjustment bending can realize.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
