[0002] A steel bar bender, one of the steel bar processing machines, has a working mechanism which is a horizontal working disc rotating on a vertical axis. Place the steel bar at the position of the dotted line in the figure. The supporting pin shaft is fixed on the machine tool, and the central pin shaft and the bending pin shaft are installed on the working disc. When the disc rotates, the steel bar will be bent.

[0003] The traditional steel bar bender has the following deficiencies: When the traditional steel bar bender bends, it usually needs to position and support the steel bar through the pin shaft. However, since the pin shaft is fixed on the machine tool, when bending steel bars of different calibers, due to the circular cross-section of the steel bar, the contact area between the steel bar and the pin shaft is small. When bending the steel bar, it may cause the steel bar to shift during the bending process, resulting in a deviation in the bending angle. Therefore, it needs to be improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] A workbench 1, with a convex plate 2 fixedly installed above the front end of the workbench 1. An adjustment groove 3 is provided on the surface of the convex plate 2, and a vertical groove 4 is provided above the rear end of the workbench 1;

[0031] A driving mechanism, which is arranged inside the vertical groove 4;

[0032] A positioning mechanism, which is arranged above the convex plate 2;

[0033] A bending mechanism, which is arranged above the workbench 1;

[0034] Among them, the bending mechanism includes a bending disc 9, the bending disc 9 is rotatably connected above the workbench 1. A fixed cylinder 10 is fixedly installed on the right side of the bending disc 9. A frame 20 is fixedly installed on the front side of the fixed cylinder 10. A screw shaft 21 is movably installed on the left side of the frame 20. A second turning knob 22 is fixedly installed above the screw shaft 21. Rectangular plates 24 are threadedly sleeved on the outer sides of both ends of the screw shaft 21. A connecting shaft 27 is movably installed inside the rectangular plates 24. The other end of the connecting shaft 27 is fixedly installed with an arc-shaped plate 28.

[0035] When the steel bar needs to be bent, first fix the steel bar through the positioning mechanism, then pass the steel bar through the fixed cylinder 10, rotate the second turning knob 22, so that the second turning knob 22 drives the screw shaft 21 to rotate. The screw shaft 21 drives the rectangular plates 24 to move inward, thereby driving the arc-shaped plate 28 to contact the steel bar, so that the connecting shaft 27 drives the movable block 26 to contract into the inside of the movable groove 25, causing the buffer spring 29 to deform and release elastic potential energy, thereby supporting and fixing the steel bar.

[0036] By passing the steel bar through the fixed cylinder 10 and rotating the second turning knob 22 to make the arc-shaped plate 28 contract inward under the action of the rectangular plates 24 to contact the steel bar, the arc-shaped plate 28 squeezes the buffer spring 29, causing the buffer spring 29 to deform and release elastic potential energy to complete the support and fixation of the steel bar. Compared with the steel bar positioning and supporting device of the traditional steel bar bender, the steel bar positioning and supporting device of this steel bar bender fixes the steel bar through the arc-shaped plate 28, effectively preventing the inconsistent diameter of the steel bar from affecting the bending result, avoiding the deviation of the bending angle caused by the sliding and offset of the steel bar, and improving the working efficiency of the steel bar bender.

[0037] Among them, the positioning mechanism includes a first pin shaft 15, the first pin shaft 15 is fixedly connected above the right end of the convex plate 2.

A second pin shaft 16 is threadedly sleeved on the outer side of the bolt 17. A first turning knob 19 is fixedly installed above the bolt 17.

[0038] Place the steel bar between the pin shaft 15 and the pin shaft 2 16, then move the pin shaft 2 16 so that the pin shaft 2 16 drives the bolt 17 to move inside the adjusting slot 3, fix the steel bar through the pin shaft 2 16 and the pin shaft 1 15, then rotate the knob 19 so that the knob 19 drives the bolt 17 to rotate, and the bolt 17 rotates inside the pin shaft 2 16 to drive the clamping block 18 to move upward, so that the clamping block 18 squeezes the upper part of the adjusting slot 3, thereby fixing the pin shaft 2 16.

[0039] When the steel bar needs to be fixed, it is only necessary to move the pin shaft 2 16, clamp the steel bar through the pin shaft 15 and the pin shaft 2 16, and then rotate the knob 19 to clamp the clamping block 18 on the upper part of the adjustment slot 3, thereby fixing the pin shaft 2 16. Compared with the steel bar positioning support device of the traditional steel bar bending machine, the steel bar positioning support device of the steel bar bending machine can fix the steel bars of different diameters by moving the pin shaft 2 16 so that the pin shaft 15 and the pin shaft 2 16 can fix the steel bars, thereby improving the working efficiency of the steel bar bending machine.

[0040] A movable groove 25 is formed inside the rectangular plate 24 , and a movable block 26 is movably installed inside the movable groove 25 . The movable block 26 is fixedly connected to the inner end of the connecting shaft 27 .

[0041] The arc plate 28 contacts the steel bar and drives the movable block 26 back to the inside of the movable groove 25 through the connecting shaft 27, thereby playing a buffering role for the arc plate 28.

[0042] Among them, the driving mechanism includes a rotating shaft 2 8, which is fixedly connected to the bottom of the bending disk 9 and located inside the vertical slot 4. A rotating shaft 1 6 is rotatably installed at the front end of the vertical slot 4. The rotating shaft 1 6 and the rotating shaft 2 8 are connected through a crawler 7. A motor 5 is fixedly installed above the rotating shaft 1 6.

[0043] The motor 5 rotates to drive the rotating shaft 1 6 to rotate, the rotating shaft 1 6 drives the rotating shaft 2 8 to rotate through the crawler 7, and the rotating shaft 2 8 drives the bending disk 9 to rotate to bend the steel bar.

[0045] The rotation of the second rotating shaft 8 drives the reset disc 11 to rotate, and the reset disc 11 drives the reset block 13 to rotate. When the work is completed, the reset spring 14 rebounds and drives the bending disc 9 back to the original position.

[0046] Among them, a limiting rod 23 is fixedly installed above the right side of the frame 20, and the limiting rod 23 penetrates through the rectangular plate 24 and extends to the bottom of the frame 20.
