[0017] The beneficial effects of the present application are: the present application is an automatic bending equipment with simple structure and effective control of the bending angle of reinforcing steel bars of different thickness, and the specific implementation method is as follows:

[0018] After the operator adjusts the position by using the mobile platform, the operator places the steel bar against the support sliding rod on the side of the support flat plate away from the mobile guide rail by using the mechanical gripper, and then starts the driving motor to rotate the meshing gear to drive the pinching gear rotating disc to rotate. In the rotating process of the gear rotating disc, the clamping bent plate clamps the bending rod to move close to the convex wheel. Since the bending rod is guided by the guide sliding rod and the inclined guide groove, the bending rod touches the steel bar in advance while moving close to the support sliding rod, so that the bending rod cannot move. Therefore, the clamping bent plate continues to drive the convex wheel to abut against the bending rod, thereby clamping the bending rod. Then, the bending rod can be twisted to rotate the rotating disc by continuously rotating the gear rotating disc, so as to realize the bending of the steel bar.

[0019] Through the above process, since the rebound effect is different when the steel bars of different thicknesses are bent, in order to realize the angle control during bending, the bending rod drives the adjusting arc-shaped rod below the connecting rod to pass between the two groups of rotating rollers in the adjusting groove while moving along the inclined guide groove. The curved adjusting arc-shaped rod drives the rotating rod to rotate while continuing to drive the rotating cylinder to rotate around the support sliding rod, so that the light transmission through hole moves in the reverse direction along the bending direction. When the angle is fixed, the rotating disc irradiates the surface of the rotating cylinder. When the predetermined bending angle is reached, the rotating cylinder rotates the light transmission through hole in the reverse direction, so that the laser detector cannot pass through the light transmission through hole to irradiate the support sliding rod. Therefore, the bending needs to be continued until the laser detector passes through the light transmission through hole to irradiate the support sliding rod, and then the reverse rotation gear rotating disc is stopped to release the clamping of the steel bar by the bending rod and the support sliding rod. The bent steel bar rebounds to the required angle after rebounding due to the multiple bending angles, thereby realizing the angle control. Meanwhile, the adjusting arc-shaped rod can be replaced to realize the bending of steel bars of different materials by adjusting the rotation angle of the rotating cylinder, or to adapt to different bending angles.

[0020] Meanwhile, the reverse rotation gear rotating disc drives the support sliding rod to rotate in the reverse direction, further drives the disengaging rod to rotate through the rotating adjusting block, so that the support sliding rod extrudes the thrust spring below the support bowl to move in the direction of the supporting plate. The part of the support sliding rod at the top of the rotating disc falls down. If continuous bending is required, the support sliding rod and the bending rod are released from clamping the steel bar after the reverse rotation gear rotating disc is rotated. Then, the position of the steel bar is moved by using the mechanical gripper, and the above bending process is repeated. If the unloading of the steel bar is required, the support sliding rod is lowered, and then the lifting rod is started to extend to drive the support flat plate to flip along the connection direction of the hinged connecting piece, thereby generating an inclined slope with a certain angle. The steel bar can flow out through the inclined support flat plate, thereby realizing the unloading of the steel bar.

[0021] The device has the advantages of simple structure, good practicability and economy, and good control effect on bending angles of different thicknesses of steel bars by using the movable clamping structure and the close distance of the rotation angle, and is beneficial to the promotion and use of the device.

[0046] Firstly, the operator adjusts the position by using the moving platform 12, and then places the steel bar on the side of the supporting flat plate 21 away from the moving guide rail 11 by using the mechanical gripper 13, and then starts the driving motor 29 to rotate the meshing gear 291 to drive the pinching gear rotating disc 27 to rotate, in the rotating process of the gear rotating disc 27, the clamping bending plate 26 drives the bending rod 23 to approach the convex wheel, and the bending rod 23 is guided by the guide sliding rod 222 and the oblique guide groove 221, so that the bending rod 23 cannot move when approaching the supporting sliding rod 24, and the clamping bending plate 26 continues to drive the convex wheel to abut against the bending rod 23, so as to clamp the bending rod 23, and then the gear rotating disc 27 is continuously rotated to drive the bending rod 23 to twist the steel bar around the supporting sliding rod 24, and the rotating disc 22 is rotated to realize the bending of the steel bar;

[0047] Through the above process, due to the different steel bending resilience effect of different thickness, in order to realize the angle of the bending, the bending rod 23 drives the adjustment arc-shaped rod 2311 below the connecting rod 231 to pass between the two groups of rotating rollers 285 in the adjusting groove 282, the bending adjustment arc-shaped rod 2311 drives the rotating rod 283 to rotate while continuing to drive the rotating cylinder 28 to rotate around the support sliding rod 24, causing the light transmission through hole 286 to move in the reverse direction along the bending direction, when the angle is fixed, the rotating disc 22 irradiates the surface of the rotating cylinder 28, and when the predetermined bending angle is reached, the rotating cylinder 28 causes the light transmission through hole 286 to rotate in the reverse direction, so that the laser detector 52 cannot pass through the light transmission through hole 286 to shoot the support sliding rod 24, so the bending needs to continue until the laser detector 52 passes through the light transmission through hole 286 to shoot the support sliding rod 24, then the reverse rotation gear rotating disc 27 can stop the bending, the bending rod 23 and the support sliding rod 24 can be separated from the clamping of the steel, the rebounded steel is fixed to the required angle after the rebound, the angle is controlled, the adjustment arc-shaped rod 2311 can be replaced, the rotating angle of the rotating cylinder 28 is changed by adjusting the arc of the adjustment arc-shaped rod 2311, the steel of different materials is bent, or different bending angles are adapted.

[0048] At the same time, the reverse rotation gear rotating disc 27 drives the support sliding rod 24 to rotate in the reverse direction, further drives the disengagement rod 241 to pass through the rotating adjusting block 35, so that the support sliding rod 24 extrudes the thrust spring 243 below the support bowl 242 to move in the direction of the bottom supporting plate 31, part of the support sliding rod 24 at the top of the rotating disc 22 falls down, if continuous bending is needed, the support sliding rod 24 and the bending rod 23 can be separated from the clamping of the steel after the reverse rotation gear rotating disc 27 is rotated, the position of the steel is moved by the mechanical gripper 13, and the above bending process is repeated, if the unloading of the steel is needed, the support flat plate 21 is flipped along the connection direction of the hinged connecting piece 43 after the support sliding rod 24 falls down, a certain angle of inclined slope is generated, and the steel can flow out through the inclined support flat plate 21, so that the unloading of the steel is realized.
