When the contact block 1103 presses the switch button 108, the output shaft 601 drives a rotating platform 2 to rotate ninety degrees counterclockwise, through the action of the transmission gear 8, the other rotating platform 2 is simultaneously rotated by ninety degrees clockwise, therefore, the reinforcing steel bar can be bent for the first time, then the output shaft 601 stops rotating, the hydraulic cylinder 3 enables the piston rod 301 to contract to drive the gear reversing component 4 and the driving motor 6 to move backwards in the inner cavity of the workbench 1, the two rotating platforms 2 also move backwards in the installation groove 101, after the piston rod 301 is completely contracted, the output shaft 601 is started again to drive one rotating platform 2 to rotate ninety degrees counterclockwise, the other rotating platform 2 also rotates ninety degrees clockwise, therefore, the reinforcing steel bars can be bent into a reinforcing steel bar frame, the sliding plate 9 and the fixing plate 104 clamp the reinforcing steel bars, dislocation of the plurality of reinforcing steel bars during bending can be avoided, and the bending quality is good.

After the reinforcing bar is bent into a reinforcing bar frame, upwards lift depression bar 11 and make sliding plate 9 keep away from fixed plate 104, contact block 1103 no longer presses shift knob 108 simultaneously for pneumatic cylinder 3 and sliding plate 9 reply initial condition according to the reverse function of the process of bending, can bend into reinforcing bar frame fast with many reinforcing bars, and to sum up, the device can be bent into reinforcing bar frame fast with many reinforcing bars, and can bend the in-process and avoid many reinforcing bars to take place the dislocation.

The spring 13 is sleeved on the sliding rod 901, two ends of the spring 13 respectively abut against the back of the lug 902 and the front of the connecting block 105, and the spring 13 is always in a compression state between the lug 902 and the connecting block 105, so that the sliding plate 9 always tends to be away from the fixed plate 104, after the reinforcing steel bar is bent, a user does not need to lift the pressing rod 11, only the pressing rod 11 needs not to be pressed downwards, the sliding plate 9 is automatically away from the fixed plate 104 through the elasticity of the spring 13, and the pressing rod 11 is automatically lifted upwards, so that the contact block 1103 does not press the switch button 108, further convenience is brought to the use of the device, and the device has the function of automatically keeping the sliding plate 9 away from the fixed plate 104 and automatically lifting the pressing rod 11 upwards after the reinforcing steel bar is bent.

There is locating plate 110 at the last fixed surface of workstation 1, locating plate 110 is close to the right side of workstation 1, and there is the intersection locating plate 110 and the positive plane at fixed plate 104, when the device is in initial condition, when putting many reinforcing bars between the upper surface of workstation 1 and mandrel 201 and the axle 202 of bending, make many reinforcing bars move to the right, make the one end of reinforcing bar all offset with locating plate 110, just can make the one end of a plurality of reinforcing bars align, can make the quality of reinforcing bar frame better after bending the reinforcing bar like this, the device has the function that can be convenient for make the one end of a plurality of reinforcing bars align in order to improve the reinforcing bar frame quality.

The device is through setting up locating plate 110, before bending the reinforcing bar and when the device is in initial condition, many reinforcing bars were put on workstation 1 and were in mandrel 201 and bend between the axle 202, made the one end of many reinforcing bars all offset with locating plate 110, just can align the one end of many reinforcing bars fast, improved the reinforcing bar and bent into the quality of reinforcing bar frame, the device has the one end that can be convenient for make a plurality of reinforcing bars and aligns the function in order to improve reinforcing bar frame quality.
