[0030] The reciprocating mechanism 4 also includes a second fixed column 404 and a connecting rod 405. The second fixed column 404 is installed on the top of the fixed block 403 by bolts. A first circular groove is opened on the left side of the connecting rod 405. The connecting rod 405 is sleeved on the second fixed column 404 through the first circular groove; the rotation of the third fixed column 406 drives the connecting rod 405 to swing, and the swing of the connecting rod 405 drives the second fixed column 404 to make a left and right linear reciprocating motion, the movement of the second fixed column 404 drives the fixed block 403 to make a linear reciprocating motion, and the movement of the fixed block 403 drives the movable plate 401 to make a linear reciprocating motion in the middle of the two limit plates 402;

[0031] The reciprocating mechanism 4 further includes a third fixed column 406 and a rotating disk 407. The rotating disk 407 is mounted on the right side of the top of the fixed plate 2 through a bearing.

A plurality of steel bars 504 are movably installed inside the storage groove 502, and a steel bar 504 is movably installed inside the first movable groove 503; when the steel bar 504 moves to the left, it hits the limit tongue 507. At this time, the steel bar 504 will give a force to the limit tongue 507, so that the limit tongue 507 moves downward until the limit tongue 507 completely drops into the limit groove 505. At this time, the limit tongue 507 no longer blocks the steel bar 504, so that the steel bar 504 can continue to move to the left until the steel bar 504 moves between the pressure head 303 and the first fixed column 304. At this time, the steel bar 504 will fall into the pressure head 303. The movable rod 302 is between the pressure head 303 and the first fixed column 304. At this time, the hydraulic tank 301 is started, and the hydraulic tank 301 will give a rightward force to the movable rod 302, so that the movable rod 302 will move to the right. The rightward movement of the movable rod 302 will drive the pressure head 303 to move to the right together. At this time, the steel bar 504 is located between the pressure head 303 and the first fixed column 304. Under the rightward movement of the pressure head 303 and the restriction of the first fixed column 304, the steel bar 504 will be bent. During the bending process, the steel bar 504 will enter the inside of the second movable groove 9. Under the limitation of the second movable groove 9, the steel bar 504 will not be lifted up during the bending process, thereby preventing the steel bar 504 from lifting up.

[0034] The discharge mechanism 5 further includes a limiting groove 505, which is provided on the left side of the top of the fixed plate 2 and has a rectangular structure; the limiting tongue 507 is no longer squeezed by the movable plate 401, so that the limiting tongue 507 returns to the upper part of the limiting groove 505 under the push of the spring 506;

[0035] The discharge mechanism 5 also includes springs 506, and there are three springs 506, which are respectively installed on the front side, the middle part and the rear side of the bottom end of the limiting groove 505 by bolts; the springs 506 provide an upward supporting force to the limiting tongue 507, so that the limiting tongue 507 can be kept above the limiting groove 505;

[0036] The discharge mechanism 5 also includes a limiting tongue 507, which is installed on the upper end of the spring 506 by bolts; the steel bar 504 inside the first movable groove 503 will not swing left and right under the common limitation of the limiting tongue 507 and the movable plate 401, so that the steel bar 504 inside the storage groove 502 will not fall into the first movable groove 503.

[0037] Working principle: When the present invention is used, the steel bar 504 is first placed inside the storage slot 502. At this time, there is also a steel bar 504 inside the first movable slot 503. When the steel bar 504 needs to be bent, the motor 408 is turned on. At this time, the output shaft of the motor 408 drives the turntable 407 to rotate. The rotation of the turntable 407 drives the third fixed column 406 to rotate together with the turntable 407. The rotation of the third fixed column 406 drives the connecting rod 405 to swing, and the swing of the connecting rod 405 drives the second fixed column 40 4 makes a linear reciprocating motion to the left and right, the movement of the second fixed column 404 will drive the fixed block 403 to make a linear reciprocating motion together, the movement of the fixed block 403 will drive the movable plate 401 to make a linear reciprocating motion between the two limit plates 402, when the movable plate 401 moves to the left, the movable plate 401 will pass through the first movable groove 503, thereby pushing the steel bar 504 inside the first movable groove 503 to move to the left, and the steel bar 504 will hit the limit tongue 507 during the leftward movement, at this time the steel bar 504 will give a force to the limit tongue 507, so that the limit tongue 507 moves downward until the limit tongue 507 completely drops into the limit groove 505. At this time, the limit tongue 507 no longer blocks the steel bar 504, so that the steel bar 504 can continue to move to the left until the steel bar 504 moves between the pressure head 303 and the first fixed column 304. At this time, the steel bar 504 will fall between the pressure head 303 and the first fixed column 304. At this time, the hydraulic tank 301 is started, and the hydraulic tank 301 will give the movable rod 302 a rightward force. The movable rod 302 moves to the right, and the rightward movement of the movable rod 302 drives the pressure head 303 to move to the right together. At this time, the steel bar 504 is located between the pressure head 303 and the first fixed column 304. Under the rightward movement of the pressure head 303 and the restriction of the first fixed column 304, the steel bar 504 will be bent. During the bending process, the steel bar 504 will enter the second movable groove 9. Under the restriction of the second movable groove 9, the steel bar 504 will not be tilted during the bending process, thereby preventing the steel bar 504 from tilting.

[0038] When the steel bar 504 is bent to a suitable angle, the hydraulic tank 301 gives the movable rod 302 a leftward force, causing the movable rod 302 to move to the left. At this time, the leftward movement of the movable rod 302 will drive the pressure head 303 to move to the left together. At this time, the steel bar 504 is no longer squeezed, and the staff can take out the bent steel bar 504. At the same time, the movable plate 401 begins to move to the right, and the movable plate 401 slowly moves to the right back to the right side of the storage box 501. At this time, the lower end of the steel bar 504 inside the storage slot 502 is no longer supported by the movable plate 401, causing the steel bar 504 to move downward under the influence of gravity, and the steel bar 504 at the bottom will fall into the first The reinforcing bar 504 in the storage slot 502 will not fall into the first movable slot 503. This cycle can be continued, and the reinforcing bar 504 can be quickly bent, and the workload of the staff can be reduced, which greatly saves the staff's energy. When the motor 408 needs to be repaired, the maintenance door 8 can be opened to repair the motor 408.
