[0004] By reviewing the above comparative documents, it can be seen that the prior art still has the following deficiencies. In the process of bending steel bars of the same batch specifications, if there is a lack of measures to quickly locate the bending length of the steel bars, each time the steel bars are bent, it is often necessary to repeatedly measure the bending length of the steel bars, which will not only increase the measurement trouble, but also affect the bending efficiency of the steel bars. In addition, the angle of the steel bars when bending is difficult to determine accurately, which can easily cause a large deviation in the angle of the steel bars, affecting the quality of the steel bars after bending.

DETAILED DESCRIPTION

[0024] A steel bar bending device for construction:

[0025] like Figure 1 As shown, in this embodiment, it includes a frame 1 and a bending table 2, the bending table 2 is fixed to the bottom end of the frame 1, an electric hydraulic cylinder 6 is fixed to the top end of the frame 1, and a bending roller 7 is rotatably connected to the power end of the electric hydraulic cylinder 6. A length positioning component is provided on the left side of the bending table 2, and the length positioning component includes a positioning plate 8, a positioning ruler 9 and a threaded adjustment rod 10. The positioning plate 8 is provided on the left side of the bending table 2, and the positioning ruler 9 is fixed between the left side of the bending table 2 and the left wall of the frame 1. The positioning plate 8 is slidably sleeved with the positioning ruler 9, and the threaded adjustment rod 10 is rotatably connected to the lower left end of the bending table 2. The threaded adjustment rod 10 rotates to the left and passes through the frame 1, and the positioning plate 8 is threadedly sleeved with the threaded adjustment rod 10;

[0026] When the device is used to bend the steel bars, the steel bars are placed on the bending table 2, and then the use position of the positioning plate 8 is adjusted according to the bending length of the steel bars. Therefore, the threaded adjustment rod 10 is turned to drive the positioning plate 8 to slide left and right along the positioning ruler 9 until the positioning plate 8 moves to the corresponding position. At this time, the distance between the positioning plate 8 and the bending table 2 is determined, and the distance is the bending length of the steel bars. Therefore, the left end of the steel bar is pressed against the right side of the positioning plate 8, which is conducive to conveniently and quickly determining the bending length of the steel bars, thereby reducing the trouble of repeatedly measuring the length of the steel bars and effectively improving the work efficiency when bending the steel bars.

[0027] like Figure 1 , 5 As shown, in this embodiment, a pressing plate 4 is provided above the bending table 2, and telescopic rods 5 are connected between the upper ends of the pressing plate 4 and the top of the frame 1 on both sides, and an electric telescopic shaft 3 is connected between the middle of the upper end of the pressing plate 4 and the top of the frame 1;

[0028] After the steel bar is placed on the bending table 2, the electric telescopic shaft 3 drives the pressing plate 4 to move downward until the pressing plate 4 presses the steel bar tightly on the bending table 2. When the pressing plate 4 moves downward, the telescopic rod 5 is driven to stretch downward. Therefore, combined with the extension and retraction of the telescopic rod 5, it is beneficial to ensure the stability of the pressing plate 4 pressing down on the steel bar, thereby preventing the steel bar from accidentally tilting up during the bending process, which is beneficial to ensuring the stability of the steel bar bending process.

[0029] like Figure 1-6 As shown, in this embodiment, a support plate 11 hinged to the upper left end of the bending table 2 is provided below the bending roller 7, an arc angle ruler 12 is fixed to the lower end of the support plate 11, an arc groove 13 is provided on the left side of the bending table 2, a return spring 14 is installed in the arc groove 13, the arc angle ruler 12 slides and extends into the arc groove 13, the end of the arc angle ruler 12 is connected to the end of the return spring 14, a positioning sleeve 17 is slidably sleeved on the outer periphery of the arc angle ruler 12, an anti-slip pad 16 is connected to the upper end of the arc angle ruler 12, a threaded anti-slip rod 18 is threadedly connected to the right end of the positioning sleeve 17, a touch switch 15 close to the notch of the arc groove 13 is connected to the left side of the bending table 2, and the positioning sleeve 17 corresponds to the touch switch 15;

[0030] After the steel bar is compressed and limited, in order to accurately determine the bending length of the steel bar, the positioning sleeve 17 is pulled to slide along the arc angle ruler 12, and the bending angle of the steel bar is predetermined by checking the position of the positioning sleeve 17 pointing to the scale on the arc angle ruler 12, and then the threaded anti-skid rod 18 is tightened and pressed on the anti-skid pad 16 to prevent the positioning sleeve 17 from accidentally sliding around the outer periphery of the arc angle ruler 12, thereby facilitating the accurate predetermination of the bending length of the steel bar, and then the touch switch 15 is set to be connected in series with the electric hydraulic cylinder 6, and the bending roller 7 is driven to move downward through the work of the electric hydraulic cylinder 6, and the bending roller 7 will press the steel bar downward. The steel bar will bend counterclockwise, and the steel bar will drive the support plate 11 to rotate counterclockwise, so the support plate 11 will drive the arc angle ruler 12 to slide into the arc groove 13, and the arc angle ruler 12 will compress the return spring 14, until the arc angle ruler 12 drives the positioning sleeve 17 to press the touch switch 15, and the touch switch 15 controls the electric hydraulic cylinder 6 to stop working. In summary, through the above operation method, after the steel bar is bent to the corresponding angle, the moving position of the arc angle ruler 12 is limited by the positioning sleeve 17, so that the bending angle of the steel bar can be determined quickly and accurately, and the occurrence of excessive deviation of the bending angle can be effectively avoided, thereby ensuring the quality of the steel bar after bending.

[0031] like Figure 1 , 5 As shown, in this embodiment, a support plate 11 hinged to the upper left end of the bending table 2 is provided below the bending roller 7, an arc angle ruler 12 is fixed to the lower end of the support plate 11, an arc groove 13 is opened on the left side of the bending table 2, a return spring 14 is installed in the arc groove 13, the arc angle ruler 12 slides and extends into the arc groove 13, and the end of the arc angle ruler 12 is connected to the end of the return spring 14;

[0032] When the steel bar is bent, the electric hydraulic cylinder 6 contracts and drives the bending roller 7 to move up and reset. Then, the rebound force of the return spring 14 drives the arc angle ruler 12 to move out of the arc groove 13. At the same time, the arc angle ruler 12 drives the support plate 11 to rotate clockwise and reset until the support plate 11 is reset to be flush with the upper end surface of the bending table 2. This facilitates the subsequent bending of the steel bars through the bending device.
