Abstract
Description
Technical Field
[0001] The utility model relates to a steel bar processing device, in particular to a steel bar straightening and bending hoop integrated production device. Background Art
[0002] During the production and preparation process of reinforced concrete prefabricated parts, the steel bars need to be bent, and then tied into corresponding shapes to form a steel skeleton, and concrete is poured. After curing and hardening, the reinforced concrete prefabricated parts are obtained. At present, when bending long strips of steel bars, a steel bar bending machine is generally used. The operator places the steel bars on the bending machine, and then the bending machine bends the steel bars. After the bending is completed, the workers need to take them out, and the overall work efficiency is low. Moreover, since the long strips of steel bars are easily affected by the outside world and slightly bent, the straightness of the steel bars does not meet the requirements. In this way, workers need to straighten them before putting them into the bending machine for bending, resulting in low efficiency of steel bar bending. Therefore, the existing technology has the problem of low steel bar bending efficiency. Utility Model Content

DETAILED DESCRIPTION
[0011] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0012] Embodiment. A steel bar straightening and bending hoop integrated production device, comprising: Figure 1-2 As shown, it includes a frame 1, a straightening mechanism 2 and a bending hoop mechanism 3 are sequentially arranged above the frame 1, and a flipping and discharging mechanism 4 is arranged below the bending hoop mechanism 3; the flipping and discharging mechanism 4 includes a moving screw assembly 401, a moving base 402 is arranged above the moving screw assembly 401, a plurality of seat bearings 403 are arranged above the moving base 402, a flipping shaft 404 is arranged on the seat bearings 403, a flipping drive assembly 405 is arranged at one end of the flipping shaft 404, and a steel bar clamping device 406 is arranged on the flipping shaft 404.
[0013] The steel bar clamping device 406 includes a bracket 461 fixed to the flip axis 404, a long L-shaped fixed clamping plate 462 is provided on the bracket 461, a movable clamping plate 463 is provided on the side of the L-shaped fixed clamping plate 462, and a group of electric telescopic rods 464 are provided between the bottom of the L-shaped fixed clamping plate 462 and the movable clamping plate 463.
[0014] The straightening mechanism 2 includes a vertical straightening roller group 201 and a horizontal straightening roller group 202 arranged along the moving direction of the steel bars.
[0015] The flipping discharging mechanism is located between the two bending hoop modules.
[0016] A driving motor is arranged under each straightening roller of the straightening roller group.
[0017] A rotation drive motor is provided below the driven center roller.
[0018] The bending hoop mechanism 3 includes two bending hoop modules distributed on the left and right; the bending hoop module includes a driven center roller 301, a ring-shaped rotating disk 302 is provided on the side of the driven center roller 301, a bending hoop roller 303 is provided on the annular rotating disk 302, and a steel bar channel is provided between the bending hoop roller 303 and the driven center roller 301.
[0019] The lower side of the annular rotating disk is exposed from the frame, and the outer wall surface of the lower part is provided with a toothed surface, and a driving gear is meshed outside the toothed surface, and the driving gear is connected to a driving motor.
[0020] The flipping discharging mechanism uses a long L-shaped fixed splint, which can limit the steel bars and prevent the longer steel bars from bending during the bending process.
[0021] The working process of the utility model is as follows: the steel bar to be bent is placed at the straightening mechanism, and the steel bar to be bent is vertically and horizontally straightened under the traction of the straightening mechanism, and then enters the bending hoop mechanism until it reaches the set position, that is, the two ends are located at the left and right bending hoop modules of the bending hoop mechanism, the discharging mechanism is turned over to fix the steel bar, and the two bending hoop modules start to work to bend the ends of the steel bar. After bending 90 degrees, the steel bar is bent, and then the discharging mechanism is turned over to start working, turning the steel bar 180 degrees, and then the moving screw assembly starts to move outward. After reaching the set position, the steel bar clamping device releases the steel bar, and the steel bar falls to the set position.
[0022] The working process of the flipping discharging mechanism: when the steel bar reaches the set position, the electric telescopic rod starts to retract, moves the movable clamping plate inward, and clamps the steel bar; after the steel bar completes the bending operation, the flipping drive motor starts to work, driving the steel bar clamping device to rotate 180 degrees, and the moving screw assembly starts to work, driving the steel bar clamping device to move outward. After reaching the set position, the flipping drive motor continues to rotate downward by a certain angle, the steel bar clamping device is released (that is, the electric telescopic rod moves outward, driving the movable clamping plate to move outward), and the steel bar falls.
[0023] Working process of the straightening mechanism: The horizontal straightening roller group includes two straightening rollers distributed front and back. The gap between the two straightening rollers is the diameter of the steel bar. After the steel bar passes through the gap, the horizontal straightening is completed. The vertical straightening roller group also includes two straightening rollers distributed up and down. The straightening rollers are independently driven to rotate.
[0024] The working process of the hoop bending module: when in the state of conveying steel bars, the hoop bending roller is located in front of the driven center roller. The rotation of the driven center roller will drive the steel bars to move; when the steel bars reach the set bending position, the driving motor starts working, driving the driving teeth and the annular rotating disk engaged with it to rotate, so that the hoop bending roller acts on the steel bars and drives them to bend.
