Abstract
The utility model discloses an arc bending machine for steel bar which is characterized in that two parallel output axles rotating simultaneously and synchronously are driven by an electric motor through belt driving, gear reduced driving and gearwheel synchronous driving. The end of the arc bending machine for steel bar installed at the work table is provided with driving active wheels while a passive active wheel moving forth and back is arranged on the work table at the vertex of a del formed by the axle centers of the driving active wheels with the work table. A feeding point is provided with a drawing-in roller. The bending deflection of the steel bar occurs when the steel bar goes in by the drawing-in roller to contact with the driving active wheel and generate extruding. The arc bending machine for steel bar has the advantages of realizing mechanization work, reducing working intensity and increasing production efficiency and production quality.
Description
The utility model relates to a kind of machine that bar bending is in the arc-shaped, particularly is 8 to 32 millimeters bar bending reinforcing bar bender in the arc-shaped with diameter.
In building engineering construction, particularly in building civil engineerings such as concrete prefabricated pipe, tunnel, culvert, often needing diameter is that 8 to 32 millimeters bar bending becomes radius greater than 600 millimeters circular shape, all be to finish in the construction at present by workman's manual operations, this manual manipulation method is not only time-consuming but also require great effort, and product quality is not high yet.Though the angle-bender product is arranged on the market, all at crooked small curvature radius reinforcing bar design, structure is very complicated, also is not suitable for the requirement of crooked larger radius of curvature circular arc.
The purpose of this utility model provide a kind of be applicable to the moment reinforcement diameter be 8 to 32 millimeters, crooked arc radius greater than 600 millimeters, can realize the reinforcing bar bender of mechanization operation.
The utility model purpose is achieved in that the utility model is made up of motor, transmission speed reducer structure and operating mechanism, do the parallel output shafts of rotating in the same way synchronously for two that it is characterized in that driving by belt transmission, gear reduction transmission and gear Synchronous Transmission by motor, shaft end is positioned at two initiatively active wheels is installed on the work top, become the place, summit of del that the passive active wheel that can do to move forward and backward is installed in the axle center with two active active wheels, charging place is equipped with drawing-inroller with first active active wheel opposite position on work top simultaneously.When reinforcing bar by drawing-inroller enter first initiatively active wheel with passive active wheel porch and when contacting, lead, under the rubbing action of passive active wheel, reinforcing bar advances and contacts with second active active wheel, contact and push with reinforcing bar by three points on three active wheels, make reinforcing bar produce flexural deformation, reach the curved arc requirement.
The utility model advantage and good effect are that machine replaces workman's handwork, can alleviate labor strength, increase work efficiency and product quality.

The embodiment explanation:
Shown in Figure 1, motor 1 is by belt transmission 2, gear reduction transmission 3, power transmission shaft 11, driving the active active wheel 6 and 7 that is installed on output shaft 5 and 10 by gear Synchronous Transmission 4 again rotates, initiatively active wheel 6 and 7 circumferential surface are circular shapes, in order to increase the frictional force with reinforcing bar 19, be carved with many grooves 8 in its surface.As shown in Figure 2, initiatively active wheel 6 and 7 is installed on 9 of the workbench side by side, passive active wheel 12 is positioned at the place, summit with active active wheel 6 and 7 one-tenth dels, and be installed on " U " profile shaft bearing 13 that to do to move forward and backward, " U " profile shaft bearing 13 with can in railroad shoe 16, do the nut 14 that moves forward and backward and be connected as a single entity, the leading screw 15 that end is equipped with handwheel 17 matches with nut 14, rotate handwheel 17 and drive leading screw 15 rotations, can drive nut 14 moves in railroad shoe 16, regulate the position of passive active wheel 12 with this, can control the radius of curvature that is bent reinforcing bar 19.Charging for convenience is at reinforcing bar 19 chargings place and the active active wheel 6 corresponding drawing-inrollers 18 that are equipped with.When reinforcing bar 19 enters when contacting with passive active wheel porch, under the frictional force effect, reinforcing bar 19 is proceeded, and enters the crush-zone of three active wheels immediately, makes reinforcing bar 19 produce flexural deformations.
