The fixed wheel 4 is installed on the operation platform 3, and the axis of the fixed wheel 4 is arranged vertically, and the position of the fixed wheel 4 on the operation platform 3 is relatively fixed, that is, the wheel center of the fixed wheel 4 cannot displace relative to the operation platform 3. The movable wheel 5 is coplanar with the fixed wheel 4 and is arranged beside the fixed wheel 4, and a clamping joint through which the flat steel passes is arranged between the movable wheel 5 and the fixed wheel 4, one end of the clamping joint is an outlet end, and the other end is an inlet end, and in use, as shown in Figure 4 , one end of the flat steel is inserted into the inlet end of the clamping joint and is passed out of the outlet end, so that the flat steel is clamped in the clamping joint. The movable wheel 5 is movably connected to the fixed wheel 4 with the central shaft of the fixed wheel 4 as the pivot, so that, as shown in Figure 5 , when the flat steel is clamped in the clamping joint, the flat steel is bent towards one side of the fixed wheel 4 by rotating the movable wheel 5 around the fixed wheel 4. A driving mechanism for driving the movable wheel 5 to rotate around the fixed shaft 403 is arranged. In order to control the angle of the bent flat steel, a position limiter 6 is arranged on the bending rotation path of the movable wheel 5, and the position limiter 6 is installed on the operation platform 3.
[0023] In order to fix the flat steel during the bending operation and avoid displacement of the flat steel caused by movement of the movable wheel 5, a clamping seat 7 is arranged on the operation platform 3, and the clamping seat 7 is located at the outlet end of the clamping joint. The clamping seat 7 is used for clamping the flat steel, and can adopt a suction disc structure to firmly suck the flat steel.
[0024] In the embodiment, the clamping seat 7 comprises a support platform 704, a clamping nut 703, a clamping bolt 702 threaded with the clamping nut 703, and an inverted L-shaped support seat 701; the support platform 704 is fixed to the operation platform 3, and the flat steel passing through the joint is supported on the top surface of the support platform 704; the support seat 701 is fixed to the support platform 704, and the clamping nut 703 is fixed on the top of the support seat 701, which supports the top surface of the support platform 704. After the flat steel passes out of the outlet end of the joint, it is supported on the support platform 704, so the top surface of the support platform 704 cannot be higher than the flat steel support surface formed by the movable wheel 5 and the fixed wheel 4, and preferably is flush with the flat steel support surface formed by the movable wheel 5 and the fixed wheel 4. The support seat 701 is used to connect the clamping bolt 702 and the support platform 704, so that the clamping nut 703 is arranged above the support platform 704 in space, so that when the flat steel is placed on the top surface of the support platform 704, the clamping bolt 702 is screwed into the clamping nut 703, the clamping bolt 702 is tightened, the bottom end of the clamping bolt 702 can abut against the flat steel 10, thereby achieving the purpose of fixing the flat steel 10.
[0025] In order to ensure the rigidity of the support platform 704, the cross section of the support platform 704 is inverted L-shaped.
[0026] The position limiter 6 can adopt a hydraulic cylinder, etc. In the embodiment, the position limiter 6 comprises a position limiting nut 601 and a position limiting bolt 602; the position limiting nut 601 is fixed to the operation platform 3, and the position limiting bolt 602 is threaded with the position limiting nut 601; when the flat steel is bent to the required angle, the end of the position limiting bolt 602 abuts against the side surface of the flat steel. The position limiter 6 adjusts the position of the position limiting bolt 602 through threaded cooperation, so that the flat steel can obtain the required bending effect, and the structure is simple and convenient to use.
[0027] The fixed wheel 4 is in the shape of an I-beam, comprising an upper fixed wheel disc 401, a lower fixed wheel disc 402 and a middle cylindrical fixed shaft 403, the upper fixed wheel disc 401 and the lower fixed wheel disc 402 being installed on the fixed shaft 403; the movable wheel 5 is in the shape of an I-beam, comprising an upper movable wheel disc 501, a lower movable wheel disc 502 and a middle cylindrical movable shaft 503, the upper movable wheel disc 501 and the lower movable wheel disc 502 being rotatably installed on the movable shaft 503; the bottom surface of the upper fixed wheel disc 401, the top surface of the lower fixed wheel disc 402, the outer lateral surface of the fixed shaft 403, the bottom surface of the upper movable wheel disc 501, the top surface of the lower movable wheel disc 502 and the outer lateral surface of the movable shaft 503 form the gap. The I-beam shape of the fixed wheel 4 and the movable wheel 5 makes the upper fixed wheel disc 401 and the upper movable wheel disc 501 limit the bottom surface of the flat steel 10 after the flat steel 10 is inserted into the gap, and the lower fixed wheel disc 402 and the lower movable wheel disc 502 limit the bottom surface of the flat steel 10, so as to avoid the flat steel 10 from slipping off the fixed wheel 4 during the bending process. During the bending process, the upper movable wheel disc 501 and the lower movable wheel disc 502 are rotatably installed on the movable shaft 503, and the movable shaft 503 rotates around the fixed shaft 403, so as to bend the flat steel by using the rolling friction between the movable shaft 503 and the flat steel 10 and the corresponding resistance provided by the fixed wheel 4 to the flat steel.
[0028] In order to connect the fixed wheel 4 and the movable wheel 5 together and ensure the integrity of the flat steel bending device, the fixed wheel 4 and the movable wheel 5 are connected by two connection plates 8 which are separately arranged on the upper side and the lower side. Specifically, one end of the connection plate 8 is fixed to the movable wheel 5, and the other end is rotatably connected to the fixed shaft 403 of the fixed wheel 4. During use, the fixed wheel 4 is stationary and provides resistance, and the movable wheel 5 rotates around the fixed wheel 4 to bend the flat steel. At the same time, the upper movable wheel disc 501 and the lower movable wheel disc 502 of the movable wheel 5 rotate, so that rolling friction is generated between them and the flat steel, which can effectively reduce the friction and reduce the risk of damaging the galvanized layer on the surface of the flat steel.
[0029] The driving mechanism is a rotating handle 9 which is fixed between the two connection plates 8.
[0030] Embodiment: adopt Φ300mm seamless steel pipe as the vertical rod 2, weld a 350mm*350mm square flat steel at the top of the vertical rod 2 as the operation platform 3, weld a 400mm*400mm square flat steel at the bottom of the vertical rod 2 as the fixed base 1, and nail the fixed base 1 to the ground with 4 screws. Weld a 60mm long solid seamless steel pipe on the operation platform 3 as the fixed shaft 403, and install two R150 circular flat steels as the upper and lower fixed wheel plates 401 and 402 of the fixed wheel 4. Weld an angle steel on the operation platform 3 as the support platform 704, weld a section of angle steel at the edge of the support platform 704 as the support seat 701, weld a clamping nut 703 at the top end of the support seat 701, and the clamping bolt 702 cooperates with the clamping nut 703 as the top wire. A 100mm long seamless threaded steel pipe is used as the rotating handle 9, two R150mm circular flat steels are used as the upper and lower movable wheel plates 501 and 502 of the movable wheel 5, and a 60mm long solid seamless steel pipe is used as the movable shaft 503. The fixed wheel, the movable wheel and the rotating handle are connected together by using two rectangular flat steels as the connecting plates 8.
[0031] In use, first, the flat steel 10 to be bent is inserted through the gap formed by the fixed wheel 4 and the movable wheel 5, and the clamping bolt 702 on the clamping seat 7 is tightened to clamp the flat steel 10, ensuring that the clamping force is appropriate and the flat steel 10 is stable. Then, according to the required bending angle and the width of the flat steel 10, adjust the limiting bolt 602 to the appropriate position. By adjusting the position of the limiting bolt 602, the desired bending effect can be achieved. Then, use the rotating handle 9 to apply appropriate force to bend the flat steel 10. During the bending process, some force may be needed to complete the bending operation. Pay attention to the smooth and uniform application of force to avoid deformation or damage to the flat steel. After the bending is completed, check whether the bending angle and shape of the flat steel meet the requirements. If further adjustment is needed, the force can be applied again for fine tuning.
