[0024] Embodiment 1: Please refer to Figures 1-2The utility model provides a reinforcing steel bar straightening cutting auxiliary equipment, including straightening machine 1, the left side of straightening machine 1 is equipped with support frame 2, and the upper end of support frame 2 is wound with the reinforcing steel bar 3 waiting for cutting, and straightening machine 1 can straighten the reinforcing steel bar 3 by tension, extrusion, traction and the like, so that the reinforcing steel bar 3 restores straight line, and it is not too much elaboration here to the specific working principle of mature technology, and the upper side right end of straightening machine 1 is fixedly installed with cutting box 4, and the inner side front end of cutting box 4 is fixedly installed with base 403, and the upper end of base 403 is provided with cutting device that can cut the reinforcing steel bar 3 neatly, and the front end of cutting box 4 is fixedly installed with the positioning plate 401 that can calibrate the reinforcing steel bar 3 towards, and the inner end of positioning plate 401 is provided with calibration groove 402, and the reinforcing steel bar 3 is arranged in calibration groove 402, is fixed in the screw hole of different height by bolt, can realize the height of positioning plate 401 is changed, to realize the flexible adjustment of more different use environment, specifically, the inner end of calibration groove 402 is rotatably installed with a plurality of support wheels, to realize the reinforcing steel bar 3 sliding in calibration groove 402 reduces friction;

[0025] Please refer to Figure 2 、 Figure 3 、 Figure 4 , cutting device includes stabilizing disc 5, and stabilizing disc 5 is fixedly installed on the upper end of base 403 by a plurality of stabilizing columns 503, and a plurality of stabilizing columns 503 are annularly distributed, to realize that stabilizing disc 5 can be provided with more stable support, and the upper end of stabilizing disc 5 is fixedly installed with stabilizing ring 515, and the upper end left side of stabilizing ring 515 is fixedly installed with two rectification clamps 514 that stabilize the end of reinforcing steel bar 3, two rectification clamps 514 correspond to each other, and the end of rectification clamp 514 close to each other is rotatably installed with a positioning wheel, to realize that reinforcing steel bar 3 is more smooth when passing, and the inner end of stabilizing ring 515 is rotatably installed with rotating disc 501, and the upper end of rotating disc 501 is provided with a plurality of rectangular holes 511, and the rectangular holes 511 are annularly distributed, and the cutting block 512 that can cut the reinforcing steel bar 3 is slidably connected in the rectangular hole 511;

[0026] The speed of rotating disc 501 rotation determines that cutting block 512 can cut reinforcing steel bar 3 of different lengths, since the speed of reinforcing steel bar 3 provided by straightening machine 1 is certain, then when rotating disc 501 rotates rapidly, continuous cutting of reinforcing steel bar 3 is realized, and the upper end of cutting block 512 is fixedly installed with limit protrusion 513, the height of limit protrusion 513 is higher than the height of rectification clamp 514, so that cutting block 512 is limited during cutting reinforcing steel bar 3;

[0027] As Figure 5As shown, the upper end of the stabilizing disc 5 is fixedly installed with a top block 510, which is isosceles triangular. Since the cutting block 512 can move up and down in the rectangular hole 511, when the rotating disc 501 rotates, the cutting block 512 moves upward under the extrusion of the triangular slope when passing through the top block 510, so that the cutting block 512 does not collide with the cutting block 512 on the right side of the rotating disc 501 during the cutting of the steel bar 3.

[0028] Embodiment 2: please refer to Figure 3 、 Figure 5 、 Figure 6 , a steel bar straightening and cutting auxiliary device, based on the basis of embodiment 1, the upper end of the base 403 is rotatably installed with a center column 502, the upper end of the center column 502 is fixedly connected with the bottom end of the rotating disc 501, the outer surface of the center column 502 is fixedly installed with a driven gear 509, the driven gear 509 is located below the stabilizing disc 5, the inner side of the cutting box 4 is fixedly installed with a support seat 504 through bolts;

[0029] The upper end of the support seat 504 is fixedly installed with an electric push rod 505, and the telescopic end of the electric push rod 505 is fixedly installed with a drive rack 506, the drive rack 506 is engaged with the driven gear 509, the upper end of the cutting box 4 is fixedly installed with a control terminal (not shown in the figure), the control terminal and the electric push rod 505 are connected through signal wires, the control terminal can control the extension speed of the electric push rod 505, and the control terminal can control the start and stop of the straightening machine 1;

[0030] The lower end of the support seat 504 is fixedly installed with a limit plate 507, one end of the limit plate 507 close to the electric push rod 505 is fixedly installed with a travel switch 508, the travel switch 508 and the control terminal are connected through signal wires, and the travel switch 508 corresponds to the telescopic end of the electric push rod 505. When the telescopic end of the electric push rod 505 extends and touches the travel switch 508, the control terminal immediately stops the advancing command of the electric push rod 505, and then the straightening machine 1 also stops supplying the steel bar 3. Specifically, when the drive rack 506 is completely pushed out, the rotating disc 501 just rotates one circle under the meshing action of the driven gear 509.

[0031] Working principle:

[0032] In use, the steel bars 3 above the support frame 2 are sequentially inserted into the straightening machine 1, and then the steel bars 3 are straightened by the straightening machine 1, and then the first end of the steel bar 3 is inserted into the calibration groove 402, and then the two correction clamps 514 are clamped.

[0033] At this time, the steel bar 3 is cut, with the starting of the straightening machine 1 and the electric push rod 505, the telescopic end of the electric push rod 505 drives the driving rack 506 to move, then the driving rack 506 drives the central column 502 to rotate the rotating disc 501 under the meshing of the passive gear 509, at this time, the cutting block 512 is cut under the rotation of the rotating disc 501, the cutting block 512 is lifted by the top block 510 before being parallel to the correction clamp 514, then the steel bar 3 is cut, then falls to the level of the rotating disc 501 under the action of gravity, avoiding the cut steel bar 3 from being stuck between two adjacent cutting blocks 512, since the speed of the straightening machine 1 pushing the steel bar 3 is certain, the faster the rotating disc 501 rotates, the shorter the length of the cut steel bar 3, on the contrary, the longer the length of the cut steel bar 3, under the continuous rotation of the rotating disc 501, the steel bar 3 can be continuously cut;

[0034] Then when the telescopic end of the electric push rod 505 touches the travel switch 508, the straightening machine 1 stops supplying the steel bar 3, and the electric push rod 505 returns to the initial state and performs the next cutting operation.

[0035] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
