[0040] When the equipment is in use, the equipment is pushed to a designated position, the fixed platform 1 is adjusted to a horizontal plane using the leveling mechanism 7, the feeding mechanism 5 guides the steel bar into the equipment, the driving mechanism 10 is started, the driving mechanism 10 drives the bending mechanism 9 to bend the steel bar, the bending mechanism 9 drives the clamping mechanism 6 to push the adaptive clamp 13 to fix the steel bar at a designated position, the clamping mechanism 6 pushes the locking mechanism 12 to lock the adaptive clamp 13, after the steel bar is bent, the driving mechanism 10 drives the resetting mechanism 11 to move, the resetting mechanism 11 drives the clamping mechanism 6 to push the locking mechanism 12 to release the lock of the adaptive clamp 13, the clamping mechanism 6 pushes the adaptive clamp 13 to release the fixation of the steel bar, at this time the bent steel bar is taken out, and the bending of the next steel bar is continued.

[0041] When the leveling mechanism 7 is used to adjust the fixed platform 1 to a horizontal plane, the adjusting handle 701 is rotated, and the adjusting handle 701 drives the adjusting shaft 702 to rotate. The rotation of the adjusting shaft 702 drives the support block 703 to move downward. After the support block 703 contacts the ground, the adjusting handles 701 are rotated one by one to adjust the fixed platform 1 to a horizontal plane. When the equipment is moved, the adjusting handle 701 is rotated in the opposite direction. The adjusting handle 701 drives the adjusting shaft 702 to rotate. The rotation of the adjusting shaft 702 drives the support block 703 to move upward. After the support block 703 is out of contact with the ground, the equipment can be moved.

[0042] When the feeding mechanism 5 guides the steel bar into the equipment, the motor 501 starts, and the output shaft of the motor 501 drives the driving wheel 503 to rotate. When the driving wheel 503 rotates to guide the steel bar into the equipment, the other driving wheel 503 rotates following the introduction of the steel bar. When the diameter of the steel bar changes, the sliding plate 504 drives the upper driving wheel 503 to slide to one side, and the tension spring 505 contracts and stretches synchronously to clamp the steel bar.

[0043] When the driving mechanism 10 is started, the output end of the hydraulic telescopic rod 1001 moves to one side, the output end of the hydraulic telescopic rod 1001 pushes the pushing seat 1003 to move to one side, the pushing seat 1003 moves to one side and pushes the pushing rack 1004 to move to one side; when the hydraulic telescopic rod 1001 is reset, the output end of the hydraulic telescopic rod 1001 moves to the other side, the output end of the hydraulic telescopic rod 1001 pulls the pushing seat 1003 to move to the other side, the pushing seat 1003 moves to the other side and pulls the pushing rack 1004 to move to the other side.

[0044] When the driving mechanism 10 drives the bending mechanism 9 to bend the steel bar, the rack 1004 is pushed to one side to push the driving gear 905 to rotate clockwise. The clockwise rotation of the driving gear 905 drives the wheel axle 904 to rotate clockwise. The clockwise rotation of the wheel axle 904 drives the wheel disc 901 to rotate clockwise. At this time, the steel bar is stuck in the through groove in the middle of the positioning block 903, and the wheel disc 901 rotates clockwise. The bending shaft 902 bends the steel bar. After the steel bar is bent, the hydraulic telescopic rod 1001 contracts and drives the rack 1004 to move to the other side to pull the driving gear 905 to rotate counterclockwise. The counterclockwise rotation of the driving gear 905 drives the wheel axle 904 to rotate counterclockwise. The counterclockwise rotation of the wheel axle 904 drives the wheel disc 901 to rotate counterclockwise. The bending shaft 902 is out of contact with the steel bar. At this time, the bent steel bar is taken out and the next steel bar is bent.

[0045] When the bending mechanism 9 drives the clamping mechanism 6 to push the adaptive clamp 13 to fix the steel bar at the specified position, the driving gear 905 is meshed with the driven gear 908, and the driving gear 905 drives the driven gear 908 to rotate. Under the action of the pushing rod 909, the driven gear 908 drives the clamping gear 910 to rotate, and the clamping gear 910 drives the clamping rack 602 to move toward each other, and the clamping rack 602 moves toward each other to push the connecting plate 601 to move toward each other, and the connecting plate 601 moves toward each other to push the adaptive clamp 13 to move toward each other, and the adaptive clamp 13 clamps the steel bar. Afterwards, the connecting plate 601 on one side contacts the pressure contact seat 607, pushing the pressure contact seat 607 to move inward, and the inward movement of the pressure contact seat 607 pushes the connecting rod 606 to move outward, and the outward movement of the connecting rod 606 pushes the active shaft 605 to move outward, and the outward movement of the active shaft 605 pushes the sliding sleeve 603 to move outward, and the outward movement of the sliding sleeve 603 pushes the clamping racks 602 on both sides to move outward, and the clamping racks 602 are disengaged from the clamping gear 910. At this time, the clamping mechanism 6 pushes the adaptive clamp 13 to clamp the steel bar, and the steel bar bending continues.

[0046] When the adaptive clamp 13 locks the steel bar, the connecting plates 601 move toward each other and push the I-blocks 1301 to move toward each other, and the I-blocks 1301 move toward each other and push the adjusting blocks 1302 to move toward each other. At this time, the clamping plate 1305 contacts the outside of the steel bar, and the clamping plate 1305 slides on the arc surface of the clamping block 1304, thereby completing the locking of the steel bar.

[0047] When the locking mechanism 12 locks the adaptive clamp 13, the active shaft 605 moves outward to push the locking shaft 1202 to move outward, and the locking shaft 1202 moves outward to push the locking block 1201 to move outward. The side of the locking block 1201 is fixedly connected with a plurality of teeth. The locking block 1201 moves outward and contacts the side of the I-block 1301. At this time, the locking block 1201 locks the I-block 1301 and fixes the steel bar at the specified position.

[0048] When the steel bar is bent, the driving mechanism 10 drives the reset mechanism 11 to move, pushing the rack 1004 to move to the other side, pushing the reset plate 1101 to move to the other side, the reset plate 1101 moves to the other side and pushes the reset shaft 1102 to move to the other side, the reset shaft 1102 moves to the other side and drives the fixed column 1103 to move to the other side, the fixed column 1103 moves to the other side to compress the reset spring 1105, the reset shaft 1102 moves to the other side and pushes the clamping rack 602 to move inward, when the reset mechanism 11 is reset, it pushes the rack 1004 to move to one side, the reset spring 1105 releases the pressure and pushes the fixed column 1103 to move to one side, the fixed column 1103 moves to one side and pulls the reset shaft 1102 to move to one side, the reset shaft 1102 moves to one side and pulls the reset plate 1101 to move to one side, and at this time the reset mechanism 11 is reset.

[0049] When the clamping mechanism 6 pushes the adaptive clamp 13 to release the lock on the steel bar, the reset shaft 1102 moves to the other side and pushes the clamping rack 602 to move inward, the clamping rack 602 moves inward and pushes the sliding sleeve 603 to move inward, the sliding sleeve 603 moves inward and pushes the driving shaft 605 to move inward, the driving shaft 605 moves inward and pushes the connecting rod 606 to retract inward, the inward contraction of the connecting rod 606 pushes the two connecting plates 601 to move in the opposite direction, at this time the clamping rack 602 is meshed with the clamping gear 910, the clamping gear 910 pushes the two clamping racks 602 to move in the opposite direction, at this time the adaptive clamp 13 is out of contact with the steel bar.

[0050] When the locking mechanism 12 is released from the adaptive clamp 13, the active shaft 605 moves inward to push the locking shaft 1202 to move inward, the locking shaft 1202 moves inward to push the locking block 1201 to move inward, the locking block 1201 moves inward and loses contact with the side of the I-block 1301, and the locking block 1201 on the I-block 1301 is now released.

[0051] When the adaptive clamp 13 releases the lock on the steel bar, the connecting plate 601 moves in the opposite direction to push the I-block 1301 to move in the opposite direction, and the I-block 1301 moves in the opposite direction to push the adjusting block 1302 to move in the opposite direction. At this time, the clamping plate 1305 is out of contact with the outside of the steel bar, and the lock on the steel bar is released. The worker can take out the bent steel bar and continue the bending operation of the next steel bar. When the diameter of the steel bar changes, the tensioning spring 1303 pulls the clamping blocks 1304 on both sides to keep the clamping plate 1305 in contact with the outside of the steel bar to ensure that the steel bar is locked.
