For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] As Figures 1-4 shown, a steel bar bending device that is convenient to use proposed by the present utility model includes a workbench 1, a placement plate 2 for placing workpieces, a positioning rod 3, a rotating disk 4, a bending plate 6, and a positioning plate 7. The placement plate 2 is connected to the workbench 1. The rotating disk 4 is rotatably arranged on the workbench 1. The bending plate 6 is arranged at the upper end of the rotating disk 4. The upper end of the rotating disk 4 and the upper end of the placement plate 2 are on the same horizontal line. The positioning rod 3 is coaxially connected to the upper end of the rotating disk 4. The positioning plate 7 is arranged on the placement plate 2. There is a gap for the workpiece to pass through between the positioning plate 7 and the positioning rod 3. The bending plate 6 can be rotated to be arranged side by side with the positioning plate 7 and fit with it. A rotating assembly for driving the rotating disk 4 to rotate is provided on the workbench 1.

[0023] In the present utility model, when the device needs to be used, the workpiece is passed through the gap between the positioning plate 7 and the positioning rod 3, and the outer peripheral surface of the workpiece is made to fit with the positioning plate 7 and the positioning rod 3, so as to complete the preliminary positioning of the workpiece, which can effectively prevent the workpiece from shaking and make the workpiece fit with the bending plate 6. The rotating disk 4 is driven to rotate by the rotating assembly. The rotation of the rotating disk 4 drives the bending plate 6 arranged thereon to rotate. When the bending plate 6 rotates, it cooperates with the positioning rod 3 to push the workpiece that fits with the bending plate 6 to bend, so as to bend the workpiece. This device can effectively complete the bending operation of the workpiece, and under the action of the placement plate 2, the workpiece can also be kept horizontal, effectively preventing the workpiece from warping and affecting the bending accuracy. And this device will also position the workpiece before bending the workpiece, so that the accuracy of the workpiece during bending can be effectively improved, and this device is convenient for positioning and simple to operate.

[0024] In an alternative embodiment, it further includes a mounting plate 5, the mounting plate 5 is connected to the rotating disk 4, the bending plate 6 is slidably connected to the rotating disk 4, the first fixing block 8 is connected to the mounting plate 5 and is located at one end of the bending plate 6 away from the positioning rod 3. A first threaded through hole is provided on the first fixing block 8, and a first screw rod 9 is threadedly arranged in the first threaded through hole. One end of the first screw rod 9 is rotatably connected to the bending plate 6, and a first handle is provided at the other end thereof. The second fixing block 10 is connected to the upper end of the placing plate 2 and is located at one end of the positioning plate 7 away from the positioning rod 3. A second threaded through hole is provided on the second fixing block 10, and a second screw rod 11 is threadedly arranged in the second threaded through hole. One end of the second screw rod 11 is rotatably connected to the positioning plate 7, and a second handle is provided at the other end thereof. Since both the positioning plate 7 and the bending plate 6 can move, the distance between them and the positioning rod 3 can be effectively changed when the positioning plate 7 and the bending plate 6 move, so that the device can be applied to workpieces with different diameters for bending operations, effectively improving the usage range of the device. When it is necessary to move the bending plate 6, only the first screw rod 9 needs to be rotated. When the first screw rod 9 rotates, it drives the bending plate 6 connected to it in rotation to move. Moreover, the first screw rod 9 is threadedly connected to the first fixing block 8, so that when there is no external force to drive the first screw rod 9 to rotate, the first screw rod 9 will not move, thereby improving the stability of the bending plate 6 during operation. The movement of the positioning plate 7 is similar to the above, so it will not be elaborated here one by one.

[0025] In an alternative embodiment, the rotating assembly includes a rotating shaft 12 and a motor 13. A first groove is provided at the side end of the workbench 1, the motor 13 is arranged in the first groove, a first through hole communicating with the first groove is provided at the upper end of the workbench 1, one end of the rotating shaft 12 is coaxially connected to the output shaft of the motor 13, and the other end of the rotating shaft 12 passes through the first through hole and is coaxially connected to the rotating shaft 12. The motor 13 drives the rotating shaft 12 to rotate, and the rotating shaft 12 rotates to drive the rotating disk 4 connected to it in rotation.

[0026] In an alternative embodiment, it further includes a fixing plate 14, a slider 15, a mounting block 16 and a bolt 19. The fixing plate 14 is connected to the side end of the workbench 1 away from the first groove. The slider 15 is connected to the fixing plate 14. A second through hole for the slider 15 to pass through is provided on each of the plurality of mounting blocks 16. The mounting blocks 16 are slidably arranged on the slider 15 and are slidably arranged on the side end of the workbench 1. A positioning block 18 is slidably arranged on the mounting block 16. The positioning block 18 can be moved to be arranged side by side and at an interval with the rotating disk 4. A third threaded through hole communicating with the second through hole is provided on the mounting block 16. The bolt 19 is threadedly arranged in the third threaded through hole, and the other end thereof can be moved to abut against the slider 15. Before performing a bending operation on the workpiece, by determining the bending position of the workpiece, the mounting block 16 is moved to a specified position. By rotating the bolt 19, the bolt 19 abuts against the slider 15, thereby completing the limitation of the mounting block 16. Thus, when bending the workpiece, the positioning block 18 can be moved to be arranged side by side and at an interval with the rotating disk 4. Thus, after the workpiece is initially positioned, the workpiece can be moved to contact the positioning block 18, thereby further positioning the length of the workpiece to be bent. After the positioning is completed, the positioning block 18 is moved back to its original position, and the bending operation is performed. Moreover, a plurality of mounting blocks 16 can be installed on the slider 15. Thus, when multiple bending operations need to be performed on a workpiece, before processing, the plurality of mounting blocks 16 can be respectively moved to appropriate positions, and then the positioning block 18 is sequentially moved to complete the positioning during subsequent bending, without moving one mounting block 16 multiple times for positioning, thereby effectively improving the simplicity of the staff when positioning the workpiece.

[0027] In an alternative embodiment, it further includes a limiting block 17. A chute is provided at the bottom end of the positioning block 18. The limiting block 17 is connected to the upper end of the mounting block 16. The upper end of the limiting block 17 extends into the chute and is slidably connected to the positioning block 18. By sliding the limiting block 17 in the chute, it can effectively prevent the staff from pushing the positioning block 18 to move out of the mounting block 16 when pushing the positioning block 18, thereby improving the stability of the device during use.

[0028] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modification examples falling within the scope and boundary of the appended claims, or equivalent forms of such scope and boundary.
