Technical field
The utility model relates to the steel bar girder welding fabrication equipment, particularly be steel bar girder lower margin bending forming mechanism.
Background technology
At present, in the construction of industries such as building,, usually reinforcement bar truss mould plate is embedded in the concrete for strengthening concrete strength.The structure of described reinforcement bar truss mould plate is: be welded into triangle reinforcing bar truss with reinforcing bar, the lower margin of steel bar girder is bent into set angle, lower margin is welded on the end template again.
The bending of described prior art diabolo steel bar girder lower margin is normally with manually finishing by means of anchor clamps.Above-mentioned prior art exists that labour intensity is big, efficient is low, ropy defective.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, a kind of bending operation of finishing continuously on the steel bar girder fabric welding moulding machine the reinforcing bar lower margin is provided, realization has the automaticity height, and quality is good, laborsaving steel bar girder lower margin bending forming mechanism.
The technical scheme that addresses the above problem is: a kind of steel bar girder lower margin bending forming mechanism, described steel bar girder lower margin bending forming mechanism is arranged on the steel bar girder both sides symmetrically, identical the including of steel bar girder lower margin bending forming mechanism structure of described steel bar girder both sides: quiet mould, moving mold, driver element and workbench; Described quiet mould is fixedly installed on moving mold top and is pressed on the backspin muscle; Described moving mold one end is arranged on the sweep of steel bar girder inboard, this sweep inboard has the angle after the moulding of bending steel bar girder lower margin, the moving mold other end connects the driver element that moves back and forth, described driver element is arranged on the steel bar girder outside and is fixed on the workbench, the angle of the Mobility Center of driver element after the centroclinal angle of steel bar girder is same as described lower margin bending.
The utility model beneficial effect is: after the utility model is arranged on the reinforcing bar welding sequence, by means of pulling equipment, make the reinforcing bar that is affected finish automatic bending lower margin operation in the stepping process.This practical new construction is simple, can adjust steel bar girder lower margin angle bending at any time.The utility model automaticity height, the steel bar girder lower margin quality height after the bending, speed is fast, reduces labor intensity, and increases work efficiency.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a triangle reinforcing bar truss cross-sectional view; Fig. 2 is the utility model structural front view; Fig. 3 is the vertical view of Fig. 2; Fig. 4 is the local enlarged front view of Fig. 2 intermediate cam shape steel bar girder one side steel bar girder lower margin bending forming mechanism; Fig. 5 is a B-B cutaway view among Fig. 2.
Need to prove that the steel bar girder in the utility model is that example describes with bending triangle reinforcing bar truss.
As shown in the figure, the utility model provides a kind of steel bar girder lower margin bending forming mechanism, described steel bar girder lower margin bending forming mechanism is arranged on steel bar girder 20 both sides symmetrically, identical the including of steel bar girder lower margin bending forming mechanism structure of described steel bar girder 20 both sides: quiet mould 2, moving mold 1, driver element 5 and workbench 8.
Described quiet mould 2 is fixedly installed on moving mold 1 top and is pressed on the backspin muscle 22.
Described moving mold 1 one ends are arranged on the sweep of steel bar girder 20 inboards, and this sweep inboard has the angle after 24 moulding of bending steel bar girder 20 lower margins; Moving mold 1 other end connects the driver element 5 that moves back and forth, and described driver element 5 is arranged on steel bar girder 20 outsides and is fixed on the workbench 8, the angle of the Mobility Center of driver element 5 after steel bar girder 20 centroclinal angles are same as described lower margin 24 bendings.Workbench 8 is supported by base 9.
Described driver element 5 has angle regulator, described angle regulator comprises: support the also movable supporting plate 6 of fixed drive unit 5, back shaft 11 before movable supporting plate 6 one side bottoms are fixed with, preceding back shaft 11 two ends are hinged on respectively on two supporting seats 12, and two supporting seats 12 all are fixed on the workbench 8; Movable supporting plate 6 opposite side two bottom sides symmetry place is fixed with back supporting seat 14 respectively, and back supporting seat 14 supports and hinged back back shaft 13, and back back shaft 13 middle parts are provided with screw, are fitted with an end of adjusting screw(rod) 7 in this screw; Two ends are that the opposite adjusting screw(rod) of rotation direction 7 other ends are fitted in the screw at lower support axle 15 middle parts, and lower support axle 15 two ends are hinged on respectively on the lower support seat of fixing with workbench 8 16; Last locking female 17 and down locking female 18 run through on the screw end face that adjusting screw(rod) 7 is fastened on back back shaft 13 and lower support axle 15 respectively.
Described driver element 5 one ends are provided with and move back and forth bar 4, and the described bar 4 that moves back and forth connects moving mold 1; The described bar 4 drive moving molds 1 that move back and forth move in guide rail 3; Described guide rail 3 is fixed on the movable supporting plate 6.
Described guide rail 3 is casings that penetrating inside, both sides is provided with slideway; Move back and forth and 4 sliding joining of bar connect guide rail 3; Fixedly install quiet mould 2 at the top of guide rail 3.
The structure that the top of guide rail 3 fixedly installs quiet mould 2 is: quiet mould 2 comprises quiet mould base 2b and is fixed on the quiet mould 2a of quiet mould base 2b one end, the groove that coincide with backspin muscle 22 is arranged on the quiet mould 2a end face, when quiet mould 2a is pressed on the backspin muscle 22, be convenient to backspin muscle 22 bendings that the lower margin 24 of 1 pair of web member 23 bottom of moving mold compresses from quiet mould 2a.
The utility model steel bar girder lower margin bending forming mechanism is the paired left and right sides that is arranged on steel bar girder 20.For increasing work efficiency, as shown in Figure 3, two pairs of steel bar girder lower margin bending forming mechanisms are set respectively in the left and right sides of steel bar girder 20, the distance between the two pairs of steel bar girder lower margin bending forming mechanisms is set according to the distance between the adjacent lower margin of steel bar girder.
