An adjusting ring A42 is rotatably arranged at the head end of the swivel 41. The head end of the adjusting ring A42 is fixedly connected to the output end of the rotating mechanism 6. The tail end of the adjusting ring A42 is an annular structure with equal spacing and is provided with a plurality of V-shaped guide grooves 421. The plurality of V-shaped guide grooves 421 are connected head to tail. A plurality of reverse limiting grooves 422 are provided on the outer edge surface of the adjusting ring A42. The reverse limiting grooves 422 are movably connected to the swivel 41 through a limiting column assembly A43. An adjusting ring B44 is fixedly arranged at the tail end of the swivel 41. The head end of the adjusting ring B44 is an annular structure with equal spacing and is provided with a plurality of centripetal grooves 441. The surface of the adjusting ring B44 is an annular structure with equal spacing. The distance structure is provided with a plurality of forward limit grooves A442, which are movably connected to the hole groove 3 through the limit column assembly B45, and a plurality of mounting assemblies A46 are provided in a ring-shaped equidistant structure in the gap between the adjusting ring A42 and the adjusting ring B44. The number of the plurality of V-shaped guide grooves 421, the plurality of centripetal grooves 441 and the plurality of mounting assemblies A46 are equal, and the two ends of the mounting assembly A46 are respectively connected to the V-shaped guide groove 421 and the centripetal groove 441, and a straightening wheel assembly 47 is arranged on the mounting assembly A46. A planetary assembly 48 is provided on the adjusting ring B44, and the planetary assembly 48 has a plurality of meshing ends, which are respectively meshed with the input ends of the plurality of straightening wheel assemblies 47.

[0022] In an embodiment of the present invention, the reverse limit groove 422 is in a triangular structure, the groove depth of the reverse limit groove 422 gradually increases in the counterclockwise direction, and the gap between the reverse limit groove 422 and the swivel 41 constitutes a reverse limit cavity; the forward limit groove A442 is in a triangular structure, the groove depth of the forward limit groove A442 gradually increases in the clockwise direction, and the gap between the forward limit groove A442 and the hole groove 3 constitutes a forward limit cavity; the limit column assembly A43 includes a limit column A431, which is movably arranged in the reverse limit cavity, and the limit column A431 and the reverse limit cavity are elastically connected by a spring A432; the limit column assembly B45 includes a limit column B451, which is movably arranged in the forward limit cavity, and the limit column A431 and the forward limit cavity are elastically connected by a spring B452. Through the above arrangement, in the static state, under the elastic force of the spring A432, the limit column A431 is in the middle of the reverse limit cavity, and under the elastic force of the spring B452, the limit column B451 is located in the forward limit cavity, so that when the adjustment ring A42 rotates in the forward direction, the limit column A431 has a force in the deep direction of the reverse limit groove 422 under the friction factor of the rotating ring 41, which has little effect on the forward rotation of the adjustment ring A42. When the adjustment ring A42 rotates in the forward direction, the limit column A431 Under the friction factor of the swivel 41, the positioning column A431 has a force toward the shallow part of the reverse limit groove 422, causing the reverse limit groove 422 to drive the swivel 41 as a whole to rotate in the opposite direction through the limiting column A431. Similarly, it can be known that the adjustment ring B44 can rotate in the opposite direction relative to the hole groove 3, but cannot rotate in the forward direction relative to the hole groove 3. Therefore, when the adjustment ring A42 rotates forward, the adjustment ring B44 does not rotate. When the adjustment ring A42 rotates reversely, the adjustment ring B44 is driven to rotate in the opposite direction as a whole through the swivel 41.

[0023] In an embodiment of the present invention, the mounting assembly A46 includes a mounting block 461, a movable column 462 is fixedly provided at the head end of the mounting block 461, a movable ring 463 is rotatably connected to the movable column 462, the movable ring 463 is movably matched with the V-shaped guide groove 421, a slider 464 is fixedly provided at the tail end of the mounting block 461, the slider 464 is slidably connected to the centripetal groove 441, and a mounting groove 465 is opened at the bottom end of the mounting block 461. Through the above-mentioned arrangement, the present invention enables the relative gap between the V-shaped guide groove 421 and the centripetal groove 441 to change when the adjusting ring A42 rotates in the forward direction relative to the adjusting ring B44, so that the movable ring 463 moves from the eccentric end of the V-shaped guide groove 421 to the centripetal end of the V-shaped guide groove 421, so that the movable column 462 drives the mounting block 461 to move, and the slider 464 slides to the centripetal end of the centripetal groove 441, and the straightening wheel assembly 47 located on the mounting block 461 moves synchronously and centripetally, so that the gap surrounded by several straightening wheels A473 becomes smaller, which is used for axial positioning and preliminary straightening of the end of the steel bar. When the adjusting ring A42 continues to rotate in the forward direction relative to the adjusting ring B44, the movable ring 463 moves from the centripetal end of the V-shaped guide groove 421 to the eccentric end of the V-shaped guide groove 421, so that the straightening wheel assembly 47 returns to its original position.

[0024] In an embodiment of the present invention, the straightening wheel assembly 47 includes a bevel gear A471 and a plurality of straightening wheels A473. The bevel gear A471 is arranged on one side of the top of the mounting block 461. A first connecting rod A472 is fixedly provided at one end of the bevel gear A471 close to the mounting block 461.

The second connecting rod A474 close to one end of the first pulley 470 passes through the mounting groove 465, extends to the outside of the mounting block 461 and is fixedly provided with a second pulley 475. The first pulley 470 and the plurality of second pulleys 475 are connected by a transmission belt 476. Through the above-mentioned arrangement, the present invention causes the bevel gear A471 to rotate, so that the first connecting rod A472 drives the first pulley 470 to rotate, and drives the second pulley 475 to rotate through the transmission belt 476, causing several straightening wheels A473 to rotate together, pushing the end of the steel bar in a rotating state into the straightening cavity surrounded by several groups of straightening wheels B52 for secondary straightening.

[0025] In an embodiment of the present invention, the planetary assembly 48 includes a plurality of connecting shafts 481, and the plurality of connecting shafts 481 are respectively arranged on one side of a plurality of centripetal grooves 441.

When the movable ring 463 moves from the centripetal end of the V-shaped guide groove 421 to the eccentric end of the V-shaped guide groove 421, the bevel gear B482 is meshed and disengaged from the bevel gear A471, and the adjusting ring A42 rotates in the reverse direction, and the rotating ring 41 and the adjusting ring B44 rotate in the reverse direction as a whole. Rotate, drive the connecting shaft 481, bevel gear B482 and planetary gear 483 to rotate synchronously, cause the planetary gear 483 to rotate relative to the inner gear ring 484, drive the connecting shaft 481 and bevel gear B482 to do planetary revolution motion, and the size of the gap surrounded by several straightening wheels A473 remains unchanged, and the mounting assembly A46 and the straightening wheel assembly 47 rotate in the opposite direction as a whole, so that the meshing state of bevel gear B482 and bevel gear A471 remains unchanged, and the rotation of bevel gear B482 drives bevel gear A471 to rotate.

[0026] In the embodiment of the present invention, the bevel gear B482 and the bevel gear A471 are both integrally connected with a guide arc bar 400 on their gear teeth.

[0028] In the embodiment of the present invention, the rotating mechanism 6 includes a servo motor 61 and a connecting ring block 62. The servo motor 61 is fixedly mounted on the top of the base 1. The connecting ring block 62 is fixedly mounted on the head end of the adjusting ring A42. A worm ring 63 is fixedly mounted on the head end of the connecting ring block 62. A worm 64 is meshedly connected to the bottom end of the worm ring 63. Both ends of the worm 64 are rotatably connected to a rotating seat 65.
