A closed-shaped polygonal reinforcement cage bending process comprises the following steps:

the method comprises the following steps: when in use, the steel wire mesh 3 is flatly placed on the top surface of the support rod 11; marking bending points on the steel wire mesh 3 by using ink lines, rotating the screw 21 in situ in the adjusting plate 22, making the slider 25 linearly move along the screw 21 along with the movement of the screw 21 by using a worm gear screw principle, making the slider 25 drive the connecting plate 24 and the mounting plate 42 to move, changing the position of the mounting plate 42 in the box body 12, making the slider 25 drive the connecting block 83 to move in the chute 23, making the connecting block 83 drive the pointer 82 to move along the scale line 81, judging the distance between the two mounting plates 42 according to the scale marked by the pointer 82 on the scale line 81, and making the pointer 82 align with the bending points on the steel wire mesh 3;

step two: the first hydraulic rod 41 and the second hydraulic rod 51 are respectively externally connected with a power supply, the first hydraulic rod 41 is opened, the first hydraulic rod 41 extends to drive the fixing plate 45, the fastener 6 and the contact beam 54 to move upwards, when the height of the fastener 6 is proper, the first hydraulic rod 41 stops operating to fix the fixing plate 45 and the contact beam 54, and when the fixing tooth block 61 on the top surface of the fixing plate 45 is overlapped with a steel bar, the fixing tooth block 61 is slid on the side wall of the rotating shaft 62 to make the fixing tooth block 61 staggered with the steel bar; rotating one of the fixed gear blocks 61 upwards to make the fixed gear block 61 drive the rotating shaft 62 in the hexagonal prism shape to rotate, the rotating shaft 62 in the hexagonal prism shape drive the other fixed gear 61 to rotate synchronously, so that the fixed gear block 61 rotates to clamp the reinforcing steel bar (as shown in fig. 4), and the fixed gear block 61 drives the connecting rod 63 to enter the groove 64; as the connecting rod 63 rotates inside the groove 64 to contact the limiting plate 72 with the arc-shaped side wall, the connecting rod 63 obliquely presses the side wall of the limiting plate 72, so as to push the limiting plate 72 to move inside the supporting plate 74 to compress the first spring 73, so that the limiting plate 72 is slowly separated from the connecting rod 63, thereby facilitating the rotation of the connecting rod 63 inside the groove 64, and when the fixing tooth block 61 is engaged with the mesh reinforcement 3, the compressed first spring 73 pushes the limiting plate 72 to cling to the side wall of the connecting rod 63, thereby preliminarily fixing the connecting rod 63, the rotating shaft 62 and the fixing tooth block 61;

step three: the second hydraulic rod 51 is opened, the second hydraulic rod 51 extends to push the bending girder 53 to upwards rotate by taking the fixed shaft 55 as a circle center, the bending girder 53 drives the rotating shaft 62 to rotate, the rotating shaft 62 rotates to drive the extrusion plate 91 with the arc-shaped side wall to rotate, two ends of the extrusion plate 91 are in a quarter circle shape, the extrusion plate 91 upwards extrudes the lifting rod 92 when rotating, the lifting rod 92 pushes the reinforcing plate 94 to upwards move to elongate the second spring 93, so that the toothed plate 95 on the top surface of the reinforcing plate 94 is clamped with the toothed plate 95 on the bottom surface of the limiting plate 72, the limiting plate 72 is fixed, the connecting rod 63, the rotating shaft 62 and the fixed toothed block 61 are fixed by the limiting plate 72, the reinforcing mesh 3 is fixed by the fixed toothed block 61, and the reinforcing mesh 3 is prevented from upwards moving, after the tooth plates 95 on the top surface of the reinforcing plate 94 are engaged with the tooth plates 95 on the bottom surface of the limiting plate 72, the contact beams 54 are further contacted with the bottom surface of the mesh reinforcement 3, and the second hydraulic rods 51 move, so that the bending girders 53 and the contact beams 54 are pushed to rotate upwards to press the bottom end of the mesh reinforcement 3, and the mesh reinforcement 3 moves upwards to be bent;

step four: when the mesh reinforcement 3 is bent, the side wall of the extrusion plate 91 is half of a circle, and when the contact beam 54 extrudes the mesh reinforcement 3, the extrusion plate 91 is always in contact with the lifting rod 92, so that the toothed plate 95 on the top surface of the reinforcing plate 94 is always engaged with the toothed plate 95 on the bottom surface of the limiting plate 72, and thus the fixing toothed block 61 is pressed downwards to engage with the mesh reinforcement 3, and the mesh reinforcement 3 is prevented from moving upwards when being bent; when the two ends of the mesh reinforcement 3 are bent by 135 ° (as shown in fig. 2), the second hydraulic rod 51 is opened, the second hydraulic rod 51 is contracted to move and drive the contact beam 54 to rotate downwards to enter the inside of the box 12, the fixed shaft 55 rotates and drives the compression plate 91 to separate from the lifting rod 92, when the contact beam 54 returns to the initial position, the first hydraulic rod 51 stops operating, at this time, the compression plate 91 separates from the lifting rod 92, and one end of the compression plate 91 abuts against the side wall of the lifting rod 92 (as shown in fig. 5), when the compression plate 91 separates from the lifting rod 92 slowly, the second spring 93 contracts and drives the reinforcement plate 94 to enter the inside of the support plate 74, so that the tooth plate 95 on the top surface of the reinforcement plate 94 separates from the tooth plate 95 on the bottom surface of the limit plate 72, and the fastener 6 is rotated, the connecting bar 63 is rotated upward to slide out of the inside of the groove 64, so that the fastener 6 is separated from the mesh reinforcement 3; opening the first hydraulic rod 41 to lower the height of the fixed plate 45, moving the mesh reinforcement 3 and rotating the threaded rod 21 to align the fingers 82 with the bending points of the mesh reinforcement 3, and similarly, bending the bending points of the mesh reinforcement 3 by 90 ° using the contact beams 54 according to the above method (as shown in fig. 9), and bending the mesh reinforcement 3 three times to form the mesh reinforcement 3 into a rectangular cage of a closed shape (as shown in fig. 10);

step five: when a polygonal steel reinforcement cage with a closed shape needs to be produced, similarly, according to the above steps, the bending angle of the steel mesh 3 is controlled by controlling the rotation angle of the contact beam 54 according to the design requirement, and the steel mesh 3 is bent for multiple times, so that the steel mesh 3 forms the polygonal steel reinforcement cage with the closed shape.
