[0015] The present invention has the following beneficial effects:

[0016] (1) The present invention simultaneously places a plurality of steel bars inside a C-shaped bag, starts a telescopic rod, drives a square shell to move, and drives a first tooth plate and a second tooth plate to move respectively. During the movement of the first tooth plate, the tooth sleeve rotates, and the tooth sleeve drives the first bending frame to rotate. During the movement of the second tooth plate, the second tooth sleeve rotates in the opposite direction, and the second tooth sleeve drives the second bending frame to rotate, so that the ends of the first bending frame and the second bending frame move toward the position limiting support frame. During the movement, the first bending frame and the second bending frame can bend the steel bars hung on the C-shaped bag, thereby bending a plurality of steel bars. The working efficiency of the device is improved, and when the steel bar is being bent, the force of the bending of the steel bar causes the C-shaped bag to drive the bearing block and the sliding rod to slide inside the slide groove, the sliding rod drives the arc rod to move, and the arc rod drives the round block to move. In the process of the two round blocks moving relative to each other, the airflow inside the arc shell enters the interior of the vertical shell through the air pipe, and the airflow pushes the vertical plate inside the vertical shell to move. When the vertical plate moves a certain distance, the airflow enters the interior of the C-shaped bag through the bent pipe, causing the C-shaped bag to expand, thereby clamping the steel bar through the C-shaped bag to prevent the steel bar from sliding when it is bent, thereby enhancing the stability of the steel bar bending.

[0017] (2) In the present invention, when air flow is injected into the bent pipe, the filling of air pressure will cause the lifting rod at the bent pipe to move upward, and the lifting rod drives the L-shaped frame to move upward, and the L-shaped frame drives the stabilizing plate to move upward, thereby locking the bottom end of the steel bar, further preventing the steel bar from sliding when it is bent, and further enhancing the stability of the steel bar bending. In the process of bending, the steel bar will squeeze the C-shaped bag. When the C-shaped bag is over-squeezed, the internal air pressure will be affected by the setting of the pressure relief valve, and the air pressure will be discharged into the interior of the special-shaped groove to prevent the C-shaped bag from exploding, thereby increasing the service life of the C-shaped bag. After the air pressure enters the interior of the special-shaped groove, the air pressure will push the polyethylene block inside the special-shaped groove to move. When the polyethylene block moves, it drives the pull rope to move. When it is limited by the sliding rod, the pull rope can drive the L-shaped frame to move upward, further enhancing the locking effect of the stabilizing plate and improving the stability of the steel bar bending.

[0018] (3) According to the present invention, when the steel bar is bent, the center of the steel bar will come into contact with the rubber ball rod, so that the steel bar pushes the rubber ball rod, and the rubber ball rod drives the traction rope to move, so that the traction rope is stretched, and the traction rope drives the two clamping frames to approach each other, and the two clamping frames drive the two clamping blocks to approach each other, so as to clamp the steel bar, further preventing the steel bar from sliding when being bent, and improving the stability of the steel bar bending. At the same time, when the two clamping frames approach each other, the airflow inside the circular hole is squeezed, so that the airflow inside the circular hole is sprayed toward the bending part of the steel bar through the exhaust pipe, thereby preventing the adhesion of iron filings at the bending part of the steel bar.

[0019] (4) In the present invention, when the vertical plate moves, the vertical plate drives the cylinder to move, and the cylinder drives the flexible ring to move, so that the flexible ring is docked with the circular groove. During the movement of the flexible ring, it can come into contact with the traction rope, thereby pushing the traction rope, thereby enhancing the pulling force of the traction rope, and enhancing the clamping effect of the two clamping blocks on the side, so that the stability of the steel bar bending is further improved. When the cylinder moves, the rubber ball rod will enter the interior of the cylinder, so that the rubber ball rod can push the air pressure inside the cylinder, and the air pressure enters the interior of the elastic tube through the cylinder, and the air pressure enters the interior of the C-type bag through the elastic tube, thereby expanding the C-type bag, improving the anti-slip effect of the C-type bag, and improving the stability of the steel bar bending.

[0040] A bearing assembly 56 is provided at one end of the air pipe 5510, and the bearing assembly 56 includes a vertical shell 561 connected to one end of the air pipe 5510, the bottom of the vertical shell 561 is fixedly connected to the top of the working shell 1, and first springs 562 are fixedly connected to both ends of one side of the inner wall of the vertical shell 561, and one end of the first spring 562 is fixedly connected to a vertical plate 563, and the outer wall of the vertical plate 563 is slidably connected to the inner wall of the vertical shell 561, and a plurality of curved pipes 564 are respectively connected to both sides of the vertical shell 561.

[0041] The outer wall of the sliding rod 555 is fixedly connected with a plurality of bearing blocks 565, and one side of the bearing block 565 is fixedly connected with a C-shaped bag 566.

The pressure relief valve 572 is arranged inside the special-shaped groove 571. A polyethylene block 574 is slidably connected to the inner wall of the special-shaped groove 571. The polyethylene material of the polyethylene block 574 can ensure flexible sliding when the special-shaped groove 571 is sealed. A rubber rope 573 is fixedly connected to one end of the polyethylene block 574. One end of the rubber rope 573 is fixedly connected to one side of the inner wall of the special-shaped groove 571. A pull rope 575 is fixedly connected to one end of the polyethylene block 574 away from the rubber rope 573. One end of the pull rope 575 passes through the sliding rod 555 and extends to the outside of the sliding rod 555. One end of the pull rope 575 away from the polyethylene block 574 is fixedly connected to the top of the L-shaped frame 568.

[0044] The inner wall of the working shell 1 is provided with an auxiliary component 58, which includes a vertical column 581 fixedly connected to the bottom of the inner wall of the working shell 1, and the outer wall of the vertical column 581 is fixedly connected with a plurality of bending blocks 582.

[0045] A traction rope 585 is fixedly connected to both sides of one end of the rubber ball rod 583, and circular holes 586 are respectively opened on both sides of the top of the bending block 582.

[0046] An exhaust pipe 587 is connected to one side of the inner wall of the circular hole 586, a clamping block 589 is fixedly connected to one side of the clamping frame 588, and cylinders 5810 are fixedly connected to both ends of one side of the vertical plate 563. One end of the cylinder 5810 passes through the vertical shell 561 and extends to the outside of the vertical shell 561. A flexible ring 5811 is fixedly connected to one end of the cylinder 5810. The purpose of this arrangement is to prevent the flexible ring 5811 from causing damage to the traction rope 585 when moving. Elastic tubes 5812 are connected to both sides of one end of the cylinder 5810. The purpose of this arrangement is to enable elastic stretching. One end of the elastic tube 5812 is connected to one side of the C-shaped bag 566.

[0047] During use, when the airflow is injected into the curved pipe 564, the filling of the air pressure will cause the lifting rod 567 at the curved pipe 564 to move upward, and the lifting rod 567 drives the L-shaped frame 568 to move upward, and the L-shaped frame 568 drives the stabilizing plate 5610 to move upward, so as to clamp the bottom end of the steel bar, further preventing the steel bar from sliding when it is bent, and further enhancing the stability of the steel bar bending. In the process of bending, the steel bar will squeeze the C-shaped bag 566. When the C-shaped bag 566 is over-squeezed, the internal air pressure will be affected by the pressure relief valve 561. The setting of 72 discharges the air pressure into the interior of the special-shaped groove 571 to prevent the C-shaped bag 566 from exploding, thereby increasing the service life of the C-shaped bag 566. After the air pressure enters the interior of the special-shaped groove 571, the air pressure will push the polyethylene block 574 inside the special-shaped groove 571 to move. When the polyethylene block 574 moves, it drives the pull rope 575 to move. Limited by the sliding rod 555, the pull rope 575 can drive the L-shaped frame 568 to move upward when it is stretched, further enhancing the clamping effect of the stabilizing plate 5610 and improving the stability of the steel bar bending.

[0048] When the steel bar is bent, the center of the steel bar will come into contact with the rubber ball rod 583, so that the steel bar pushes the rubber ball rod 583, and the rubber ball rod 583 drives the traction rope 585 to move, so that the traction rope 585 is stretched, and the traction rope 585 drives the two clamping frames 588 to approach each other, and the two clamping frames 588 drive the two clamping blocks 589 to approach each other, thereby clamping the steel bar, further preventing the steel bar from sliding when bending, and improving the stability of the steel bar bending. At the same time, the two clamping frames 588 squeeze the air flow inside the circular hole 586 during the process of approaching each other, so that the air flow inside the circular hole 586 is sprayed toward the bending part of the steel bar through the exhaust pipe 587, to prevent the adhesion of iron filings at the bending part of the steel bar.

[0049] When the vertical plate 563 moves, the vertical plate 563 drives the cylinder 5810 to move, and the cylinder 5810 drives the flexible ring 5811 to move, so that the flexible ring 5811 is docked with the circular groove 584. During the movement of the flexible ring 5811, it can come into contact with the traction rope 585, thereby pushing the traction rope 585, enhancing the pulling force of the traction rope 585, and enhancing the clamping effect of the two clamping blocks 589 on the side, so that the stability of the steel bar bending is further improved, and when the cylinder 5810 moves, the rubber ball rod 583 will enter the interior of the cylinder 5810, so that the rubber ball rod 583 can push the air pressure inside the cylinder 5810, and the air pressure enters the interior of the elastic tube 5812 through the cylinder 5810, and the air pressure enters the interior of the C-type bag 566 through the elastic tube 5812, so that the C-type bag 566 is expanded, thereby improving the anti-slip effect of the C-type bag 566 and improving the stability of the steel bar bending.
