[0048] Working principle:

[0049] According to the need, a certain number of steel bars 6 are selected and each of the steel bars 6 is sequentially horizontally arranged on the plurality of supporting rollers 521 in the feeding rack 520, but the number of the steel bars 6 cannot be greater than the number of the positioning grooves 5181 on the positioning block 518; then, the rocker arm 529 in the loosening prevention assembly is manually rotated to drive the rotating disc 528 to rotate, and then the two arc-shaped inclined surfaces 5282 and the heads of the two jacking screws 530 are cooperated with each other to upwardly jack up the movable beam 524, so as to drive the two second guide columns 512 to move upwardly by means of the two second springs 526 and the second nuts 527 on the two second supporting columns 525, and then the two side blocks 511 are moved upwardly by means of the two second guide columns 512, so as to drive the upper straightening roller 59 to move upwardly to expand the spacing between the two straightening rollers 59, and simultaneously make the two gears 519 separate from each other; then each of the steel bars 6 is moved leftward to sequentially pass through a corresponding annular straightening groove 591 on the lower straightening roller 59, a corresponding positioning groove 5181 and a corresponding cutting groove 561 on the cutting block 56 located on the top of the table plate 52, and then continuously move leftward from the top of the transition plate 523.

[0050] In the initial state, the bending pin 26 in each of the bending assemblies is located above a reference pin 25 on the same side, and when each of the steel bars 6 continuously moves leftward, it first passes between the bending pin 26 and the reference pin 25 in the bending assembly on the right side, then slides over the top of the supporting plate 213, and finally passes between the bending pin 26 and the reference pin 25 in the bending assembly on the left side.

[0051] Then, the rocker arm 529 is reversed by hand to drive the rotating disc 528 to reverse, and then the upper straightening roller 59 is driven to move downward to reduce the distance between the two straightening rollers 59 and make the two gears 519 mesh with each other, and each ring-shaped straightening groove 591 on the upper straightening roller 59 is fitted on the corresponding reinforcing steel bar 6 to press the reinforcing steel bar 6; then the telescopic end of the lifting cylinder 57 in the cutting mechanism 5 is driven to retract inward to drive the dynamic pressing block 513 and the upper cutting block 56 in the pressing assembly to move downward by the second lifting plate 54, the four lifting columns 55 and the first lifting plate 53, and the bottom of the dynamic pressing block 513 is lower than the bottom of the cutting block 56, so the dynamic pressing block 513 first presses each reinforcing steel bar 6 located on the top of the fixed pressing block 518, and when the upper cutting block 56 and the lower cutting block 56 are staggered with each other, each reinforcing steel bar 6 is cut by shearing force.

[0052] Then, the telescopic ends of the bending cylinders 28 in the two bending assemblies are simultaneously driven to extend outward to drive the two swinging shafts 23 to rotate in opposite directions by the two traction arms 27, and then the two bending pins 26 are driven to eccentrically rotate around the same reference pin 25 in opposite directions by the two limiting seats 24, so that the two ends of each cut reinforcing steel bar 6 are bent downward by 90 degrees.

[0053] Then, the telescopic ends of the two pushing cylinders 212 in the pushing assembly are driven to extend outward to drive the cross beam 29 and the two pushing columns 210 to move forward by the two transmission rods 211, and then the reinforcing steel bars 6 that are bent and stay between the two reference pins 25 are pushed to move forward, until each bent reinforcing steel bar 6 moves between the two supporting rods 42 in the storage mechanism 4, and then the cutting and bending of the next batch of reinforcing steel bars 6 can be repeated.

[0054] When the reinforcing steel bars 6 between the two supporting rods 42 reach a certain number, the telescopic end of the moving cylinder 43 is driven to extend outward to drive the two supporting rods 42 to move forward by the bracket 41, and then the bent reinforcing steel bars 6 are driven to move forward; at the same time, the moving end of the rodless cylinder 32 in the moving-out mechanism 3 is driven to move backward to drive the anti-falling unit to move backward by the U-shaped bracket 33, until the rear ends of the two traction arms 34 in the anti-falling unit extend below each bent reinforcing steel bar 6, and then the telescopic end of the traction cylinder 36 is driven to extend outward to drive the shaft rod 35 to move downward, and then the rear ends of the two traction arms 34 are driven to rise upward by the sliding connection between the shaft rod 35 and the rear ends of the two traction arms 34 to tilt and lift each bent reinforcing steel bar 6, and then each bent reinforcing steel bar 6 is slid onto the two traction arms 34, and then the moving end of the rodless cylinder 32 is driven to move forward, and then each bent reinforcing steel bar 6 is driven to move forward in the same way, and finally the operator can take out all the reinforcing steel bars 6 by hand.

[0055] The utility model discloses can integrate the cutting and bending process of steel bar together, and the steel bar after cutting can directly carry out bending processing without blanking and shifting, which greatly simplifies the operation process to reach the effect of time saving and labor saving, and the steel bar is automatically stored after bending, and when the stored steel bar reaches a certain number, it is automatically pushed out to save the manual operation link, thereby significantly reducing the labor intensity, in addition, the single cutting and bending operation can be carried out on multiple steel bars at the same time, thereby effectively improving the processing efficiency.

[0056] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
