Description
Technical field
The utility model relates to a kind of right angle angle-bender that can crooked square reinforcing bar.
Background technology
China at present just energetically development foundation construction is set, in the infrastructure project operation, need to use a large amount of frameworks of steel reinforcement to build the reinforced concrete foundation structure.Framework of steel reinforcement at different structure need for speeding up the work, improve engineering efficient with difform reinforcing bar product, and bending of existing reinforcing bar product all adopts angle-bender to make.
The patent No. is that 200520015176.0 Chinese utility model patent specification discloses a kind of angle-bender, this angle-bender comprises body, body is provided with workbench, be provided with motor in the body, motor is connected with mandrel by gearbox and one-way clutch, workbench is passed in the upper end of mandrel, upper end at mandrel is set with core sleeve, coaxially on mandrel be equipped with crooked swing arm, crooked swing arm upper end is connected with the adjustment slide block, is provided with roller at an end of adjusting the close mandrel of slide block.Because this angle-bender is when work, crooked swing arm is to be bent to form needed angle by the end that the roller on the adjustable skid promotes reinforcing bar around core sleeve, therefore form the bigger arc-shaped structure of a kind of radian in the reinforcing bar bending place, make that its scope of application is less, be not suitable for bending the reinforcing bar product that some have right-angle structure, hindered the promotion and application of this angle-bender.
The utility model content
The purpose of this utility model is: a kind of right angle angle-bender is provided, can not crooked has the problem of the reinforcing bar product of right-angle structure to solve above-mentioned angle-bender.
The technical solution of the utility model is: a kind of right angle angle-bender, comprise cabinet, the end face of cabinet is provided with workbench, power transmission shaft by vertical rotation assembling between cabinet and workbench is equipped with swing arm, the end of swing arm is equipped with the adjustable installing plate that extends in the same way by the mount pad of vertical setting, adjustable installing plate is equipped with roller near an end of power transmission shaft, the lower end of described power transmission shaft is connected with driving mechanism, the table top of workbench is stretched out in its upper end, upper end at power transmission shaft is arranged with axle sleeve, a side of workbench be fixed with and axle sleeve and roller between the reinforcing bar baffle plate of gap corresponding matching, described axle sleeve comprises the trepanning that axially runs through its two ends end face, corresponding described reinforcing bar baffle plate is provided with plane of orientation in parallel on the outer peripheral face of axle sleeve, be provided with the shaping plane that described plane of orientation intersects vertically at axle sleeve away from a side of reinforcing bar baffle plate, the circumcircle on described plane of orientation and shaping plane is coaxial with trepanning.
Intersection on described plane of orientation and shaping plane is provided with chamfering.
Owing to be provided with two plane of orientations that intersect vertically mutually and shaping plane on the outer peripheral face of axle sleeve, reinforcing bar is being promoted when axle sleeve is crooked by swing arm, the rigidity of utilizing reinforcing bar self to have, make its with axle sleeve between formation face contact, thereby make reinforcing bar be bent to form the right angle along two planes that intersect vertically, make the product of the reinforcing bar that existing angle-bender can crooked rectangular configuration, enlarged the scope of application of existing angle-bender, and it only is to improve on the crowded basis of the axle sleeve that has angle-bender now, it has saved a large amount of scrap build expenses, has reduced the manufacturing cost of equipment accordingly.

Fig. 2 is the structural representation of Fig. 1 bottom bracket axle.
The specific embodiment
The specific embodiment of right angle of the present utility model angle-bender as shown in Figure 1 and Figure 2, it comprises cabinet 1, the top of cabinet 1 is provided with workbench 2, side at workbench 2 is provided with the reinforcing bar baffle plate 10 that is used for spacer bar, and this reinforcing bar baffle plate 10 is connected on the positioning seat 8 that is fixedly mounted on the workbench 2 by adjustable bolt 9.Power transmission shaft 4 by vertical transmission assembling between the end face of workbench 2 and cabinet 1 is rotatably equipped with swing arm 5, and this power transmission shaft 4 is in transmission connection by reduction box and drive motors, realizes the reciprocally swinging of this swing arm 5 by the rotating of drive motors.End in swing arm 5 vertically is provided with mount pad, is equipped with and swing arm 5 adjustable installing plates 6 parallel and that extend in the same way by bolting on the mount pad, is provided with the adjustment bolt 7 that is used to adjust adjustable installing plate 6 positions between mount pad and adjustable installing plate 6.Swing arm 5, adjustable installing plate 6, reinforcing bar baffle plate 10 and the power transmission shaft 4 common angle-bender structures of forming.Be rotatably equipped with roller 11 in the adjustable end bottom that version 6 close power transmission shafts 4 are installed, the mount pad of corresponding swing arm 5 is provided with the guide rail 3 of circular arc on workbench 2.Upper end at power transmission shaft 4 outstanding workbench 2 is set with the movable axle sleeve 12 that cooperates with roller 11.At the central shaft of this axle sleeve 12 to being provided with the center trepanning 12-3 that runs through its two ends end face, corresponding reinforcing bar baffle plate 10 is provided with the plane of orientation 12-1 parallel with the stopping surface of this reinforcing bar baffle plate 10 on the outer peripheral face of axle sleeve, axle sleeve 12 is provided with the shaping plane 12-2 that intersects vertically with plane of orientation 12-1 away from a lateral circle surface of reinforcing bar baffle plate 10, and the circumcircle between these two plane of orientation 12-1 that intersect vertically and the shaping plane 12-2 is coaxial with trepanning 12-3.
During use, reinforcing bar in requisition for bending is adjusted the position of adjustable installing plate 6 by adjusting bolt 7, make the diameter of spacing between roller 11 and the axle sleeve 12 and reinforcing bar adaptive, the stopping surface that then reinforcing bar is being pasted reinforcing bar baffle plate 10 is inserted in the spacing between roller 11 and the axle sleeve 12, one end of reinforcing bar and the plane of orientation 12-1 on the axle sleeve 12 fit, a part that is reinforcing bar is cooperated block by reinforcing bar baffle plate 10 and axle sleeve 12 simultaneously, start angle-bender, drive motors drives power transmission shaft 4 rotations by reduction box, power transmission shaft 4 drives adjustable installing plate 6 rotations by swing arm 5, roller 11 promotes axle sleeve 12 rotations of an end of reinforcing bar around power transmission shaft 4, because reinforcing bar self has certain rigid, thereby reinforcing bar is that fulcrum is bent to form right-angle structure with two intersections of intersecting planes under the promotion of roller 11.For preventing that intersection between plane of orientation 12-1 and the shaping plane 12-2 at bending time damage rebar surface, is provided with chamfering structure in the intersection of two plane 12-1 and 12-2 in the utility model.
