Description
Technical field
The utility model relates to machining equipment, is specifically related to two pivoted arm hydraulic pressure stretch benders.
Background technology
Some heavy constructions often need to be processed certain radian with section bar, with globality and the aesthetic property of realizing building frame, the existing stretch benders in market mainly are divided into turntable stretch-bending machine and two pivoted arm stretch benders, and it adopts all-hydraulic control, easy and simple to handle, production efficiency is high; Its stretch bending excellent performance, the product of processing is met the need of market substantially, but the various steel pipes of the following section of clod wash 500mm, square tube, H shaped steel, I-steel, channel-section steel, angle bar, band iron and aluminium section bar, after stretch bending, camber is perfect, precision is high, good stability, non-modification.But also manifest gradually through its drawback of long-term practice, as process the big-length section bar, in the situation that main device can meet job requirements, limited by subtable, enterprise often needs the stretch benders of changing larger model to implement operation, and it has increased the unnecessary production cost spending of enterprise.
Summary of the invention
The utility model has solved the deficiencies in the prior art, provides a kind of simple in structure, can significantly improve two pivoted arm hydraulic pressure stretch benders of stretch bending operating efficiency.
For solving the problems of the technologies described above, the two pivoted arm hydraulic pressure stretch benders of the utility model, comprise the operation bench be connected with motor, described motor one side is provided with left and right chain extension bar, described left and right chain extension bar connects with corresponding left and right stretching oil cylinder one end, the other end of described left and right stretching oil cylinder is flexibly connected with corresponding left and right pivoted arm, is provided with corresponding left and right hydraulic piston on described left and right pivoted arm, and described left and right hydraulic piston seat is provided with corresponding left and right chuck; Also be provided with wing workbench on described left and right chain extension bar, on described wing workbench, be provided with some hollow holes.
Wing workbench of the present utility model can meet the stretch bending job requirements of big-length section bar, is provided with some hollow holes on wing workbench in order to fixed mould.The front staff of stretch bending operation enforcement need to be fixedly installed corresponding arc at hollow hole by mould according to the stretch bending radian, then clamps the section bar two ends by left and right chuck; Operating personnel control the hydraulic system operation by operation bench, left and right stretch bending oil cylinder in operation moves after driving left and right pivoted arm one end, move at the section bar two ends that simultaneously clamp by chuck, and moving process medium section stage casing is subject to arc the retardance of mould to be set, progressively to complete the stretch bending operation.
The utility model is simple in structure, easy to operate, is not increasing under enterprise's production cost prerequisite, only needs the improvement of workbench just can realize the stretch bending operation of big-length section bar.
The accompanying drawing explanation
Fig. 1 is the utility model inactive state top view;
Fig. 2 is the utility model duty top view.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Fig. 1, shown in Fig. 2, the two pivoted arm hydraulic pressure stretch benders of the utility model, comprise the operation bench 1 be connected with motor 2, described motor 2 one sides are provided with a left side, right chain extension bar 3, 3 ', a described left side, right chain extension bar 3, 3 ' with a corresponding left side, right stretching oil cylinder 7, 7 ' one end connects, a described left side, right stretching oil cylinder 7, 7 ' the other end and a corresponding left side, right-hand rotation arm 8, 8 ' is flexibly connected, it is characterized in that: a described left side, right-hand rotation arm 8, be provided with a corresponding left side on 8 ', right hydraulic piston 4, 4 ', a described left side, right hydraulic piston seat 4, 4 ' is provided with a corresponding left side, right chuck 5, 5 ', also be provided with wing workbench 6 on described left and right chain extension bar 3,3 ', on described wing workbench 6, be provided with some hollow hole 6a.
The left and right hydraulic piston seat of the utility model 4,4 ' is corresponding is provided with left and right chuck 5,5 ', and this left and right chuck 5, play to section bar the effect of being fixedly clamped during 5 ' operation; Be provided with some hollow hole 6a on workbench 6, operating personnel can arrange mould according to the radian of the required stretch bending of section bar; Left and right stretching oil cylinder 7, an end of 7 ' and corresponding left and right pivoted arm 8,8 ' is flexibly connected, by operation bench 1 primer fluid pressure device, drive left and right stretching oil cylinder 7 after motor 2 work, move after 7 ' one end, simultaneously by left and right chuck 5, move to motor 2 one sides simultaneously at 5 ' fixing section bar two ends, and moving process medium section middle part is subject to the mould that arranges early stage to block gradually stretch bending to required radian.
The utility model inactive state bottom left, right-hand rotation arm 8,8 ' arranges point-blank, one end of left and right stretching oil cylinder 7,7 ' is flexibly connected with corresponding left and right pivoted arm 8,8 ', left and right stretching oil cylinder 7,7 ' the other end connects with corresponding left and right chain extension bar 3,3 ', the left and right stretching oil cylinder 7 after fixing, 7 ' becomes gusseted with left and right pivoted arm 8,8 '.During enforcement, operating personnel are by the hollow hole 6a fixed mould of wing workbench 6, and the mould of maintenance projection cambered surface is consistent with the required stretch bending radian of section bar; The staff clamps the two ends of section bar again by left and right chuck 5,5 ', carry out the front preparation of stretch bending.By operation bench 1, motor 2 primer fluid pressing systems, left and right stretching oil cylinder 7 during hydraulic work system, 7 ' drives left and right pivoted arm 8 simultaneously, after 8 ' one end, move, move thereafter retardance that section bar stage casing simultaneously is subject to mould progressively stretch bending to required radian, powered-down after the stretch bending operation completes, loose left and right chuck 5,5 ', get section bar and fulfil assignment.
The utility model is simple in structure, easy to operate, and wing workbench 6 arranges and can make stretch bending be increased to 8M by 6M, has met the stretch bending job requirements of big-length section bar under the prerequisite that does not increase extra means, effectively reduces enterprise's production cost.
