A steel bar push block 303 is provided on the top of the cylinder movable block 302, and the steel bar push block 303 cooperates with multiple clips 108.

[0041] The mounting platform 104 is driven by the servo motor 106, and is moved horizontally by the transmission of the gear 107 and the rack 105 and the positioning of the moving block 103 of the guide rail 102, so that the clip 108 can be transported to the feeding position in turn, and then the tie bars in the clip 108 are sent to the right end steel bar tie machine 2 by the conveying cylinder 301; during the process, the clip 108 is moved to the conveying cylinder 301 by the servo motor 106, the gear 107 and the rack 105, and the conveying cylinder 301 is started. The conveying cylinder 301 uses a magnetically coupled rodless cylinder. When the cylinder is started, the cylinder movable block 302 drives the steel bar push block 303 to move and push the steel bar into the right side steel bar pulling machine, thereby achieving the purpose of automatic feeding. The operation of the mechanical structure replaces manual feeding, which reduces labor costs and improves efficiency, thereby improving production efficiency and output.

Finally, two bending hoop mechanisms 8 bend the steel bars at the same time. During the process, no manual operation is required, which reduces labor costs and improves efficiency, thereby improving overall production efficiency and output.

[0044] The lifting mechanism 5 includes a bracket 501 installed on the top of the base frame 4, the bracket 501 is composed of three vertical rods 502 connected, and the three vertical rods 502 are arranged horizontally in sequence, and the left and right vertical rods 502 of the bracket 501 are evenly distributed with slide rails 503, each of the slide rails 503 is provided with a plurality of sliders 504, and the plurality of sliders 504 are commonly connected to a lifting platform 505, a rack 2 506 is provided on the middle vertical rod 502 of the bracket 501, a lifting motor 507 is provided on the lifting platform 505, and a gear 2 508 meshing with the rack 2 506 is provided on the output shaft of the lifting motor 507.

[0045] The height of the tie-rebar feeding mechanism 1 is at the lower end of the steel bar pulling machine 2, so it is necessary to connect the guiding and telescopic mechanism 7 with the tie-rebar feeding mechanism 1 through the lifting mechanism 5 to complete the transfer of the steel bars; the lifting motor 507 drives the gear 2 508 to rotate, and the gear 2 508 is engaged with the rack 2 506, and with the cooperation of multiple sliders 504 and slide rails 503, the lifting platform 505 can move up and down, and can be raised or lowered to the specified position according to needs to facilitate the subsequent mechanism operation.

[0047] After the steel bar passes through the steel bar feeding mechanism 1 and enters the receiving and telescopic mechanism 7, the telescopic motor 603 starts to drive the servo electric cylinder 602 to move. Due to the limited length of the steel bar, the servo electric cylinder 602 drives the movable table 606 to move toward another steel bar pulling machine 2. A proximity switch is provided at the connection point, and the proximity switch can be used for better docking. The steel bar is moved to the receiving and telescopic mechanism 7 of the other steel bar pulling machine 2, and the two bending hoop mechanisms 8 are started synchronously to bend the steel bars.

[0049] When the tie bar enters the right-side steel bar tie machine 2 from the tie bar feeding mechanism 1, the telescopic cylinder 704 of the receiving groove 701 is started, and the receiving groove 701 is pushed to the tie bar feeding entrance through the cooperation of the receiving rail 702 and the receiving block 703, and then the conveying cylinder 301 sends the tie bar into the steel bar receiving guide groove 803 to complete the loading of the steel bar, and then cooperates with the electric telescopic mechanism to transport the steel bar to the left-side steel bar tie machine 2, and then the bending hoop mechanisms 8 on the two steel bar tie machines 2 perform the bending operation at the same time to complete the processing of the tie bar.

[0050] The bending hoop mechanism 8 includes a bending hoop cylinder 801 hingedly mounted on a movable table 606, a connecting rod 802 hingedly mounted on the output end of the bending hoop cylinder 801, the other end of the connecting rod 802 is hinged on the movable table 606, a guide groove 803 is opened on the movable table 606, and the guide groove 803 is arc-shaped, a bending hoop head 804 is provided on the connecting rod 802, and the bending hoop head 804 is located in the guide groove 803, a shifting block cylinder 805 is provided at the front end of the movable table 606, an L-shaped plate 806 is provided at the output end of the shifting block cylinder 805, and a steel bar shifting block 807 is provided on the L-shaped plate 806.

[0051] After the tie bar is transported to the designated position, the bending hoop cylinder 801 is opened, and the bending hoop cylinder 801 drives the connecting rod 802 to move, and at the same time drives the bending hoop head 804 to move in the guide groove 803. The bending hoop head 804 moves along the guide groove 803 to bend the steel bar, and then the steel bar pusher block 807 cylinder 805 is started to push the tie bar out of the bending hoop steel bar slot.

[0052] A plurality of spring clips 705 are arranged in the receiving groove 701; the shift block in the spring clip 705 has the characteristic of unidirectional movement, and the steel bar will encounter less resistance when moving to the left through the shift block, but will encounter great resistance and cannot move when moving to the right; therefore, in the process of repeated opening and closing of the telescopic cylinder 704 of the steel bar receiving groove 701, the tie bar is continuously transported to the left until it is transported to the steel bar tie machine 2 on the left.

[0053] Each of the magazines 108 is provided with two ammunition chambers 9, and the lengths of the two ammunition chambers 9 are different; the two ammunition chambers 9 on each magazine 108 have different lengths, allowing steel bars of different sizes to be stored respectively. This design can flexibly meet the specific requirements of different engineering projects, and can also compactly arrange the steel bars, effectively utilize the storage space, and meet the production requirements.
