During the decoration construction process, it is difficult to bend the steel bars (with a diameter of 6-10 mm) in the ground project construction and the outdoor step construction. It is difficult for the small-diameter steel bars to be processed and returned to the site for the second time. It is difficult to arrange the steel bar processing site in the decoration stage, and the bending processing efficiency of the small-diameter steel bars is low. Content of the Utility Model

[0003] The purpose of the utility model is to provide a bending device for small-diameter steel bars, with a reasonable structure, time-saving and labor-saving, capable of bending steel bars at multiple angles, improving the bending processing efficiency of steel bars, effectively solving the sporadic steel bar bending during the outdoor construction process, and avoiding the great difficulty in the secondary layout of the steel bar processing site and the difficulty in the return of the steel bar processing machinery to the site.

[0004] The purpose of the utility model is realized as follows: A bending device for small-diameter steel bars is composed of a channel steel forming a trough-shaped support with the opening facing downwards. On the center line of the web plate at one end of the trough-shaped support, a first support shaft and a second support shaft are fixedly connected. On the end face of one end of the long strip-shaped pressing rod, a hinge hole and a third support shaft are successively arranged. The hinge hole of the pressing rod is matched with the second support shaft. Two sets of bearings are installed in a matching manner on the second support shaft passing through the pressing rod. Two sets of bearings are respectively installed in a matching manner on the first support shaft and the second support shaft. The trough-shaped support with the opening facing downwards is fixedly connected to the operation table.

[0005] The utility model is made by combining steel plates, 5# channel steels, bolts and bearings. First, fix the channel steel to the workbench, drill two holes with an electric drill. Fix two bearings with bolts in one hole; then install an additional steel plate in the other hole, also drill holes in the steel plate with a machine, and fix two bearings in the same way. In this way, a steel bar bending machine is made, which is not only time-saving and labor-saving in use, but also can bend steel bars at multiple angles.

[0006] The installation process of the utility model is simple. Drill holes in the steel plates and channel steels according to the illustrated content with an electric drill, then place bearings with an inner diameter equal to the hole diameter at the hole positions, and reliably connect the steel plates, channel steels and bearings with bolts.

[0007] Usage Process:

[0008] Place the steel bar in the middle of the bearings, hold the steel plate by hand, and apply force clockwise to bend the steel bar to the required angle. Beneficial Effects

[0009] It is convenient to install, easy to disassemble, light to move, material-saving, and simple to operate. It can be made with steel plates and channel steel cuttings, and can be widely used in the sporadic steel bar processing (bending) during the engineering decoration stage and outdoor engineering construction.

[0010] (1) Convenient to install and easy to disassemble

[0011] Adopting bolt connection, it can be assembled quickly, is convenient to install, easy to disassemble, and has a flexible usage method.

[0012] (2) Material-saving and reusable

[0013] It avoids the drawback that subsequent materials can only be processed by cutting due to welding. It can be made with steel plates and channel steel cuttings, saving materials. Moreover, using bolt connection enables multiple uses and avoids waste caused by single-use.

[0014] (3) Light to move and wide application scenarios

[0015] The structure is light, convenient to hold and move, and can be adapted to steel bars of different diameters by replacing bearings. Brief Description of the Drawings
