[0003] Currently, traditional disc-pull diameter reduction synchronous guide mechanisms have the following drawbacks: 1. The spacing between guide wheels is not easy to adjust, making it difficult to quickly adapt to metal pipes of different specifications, resulting in a limited range of applications; 2.

[0017] Please see Figure 1-6 A disc-pulling diameter reduction synchronous guide mechanism includes a mounting base 1, a mounting groove 2 on the top of the mounting base 1, a vertical plate 3 fixedly connected to the left side of the mounting base 1, a guide hole 4 penetrating the surface of the vertical plate 3, a guide tube 5 fixedly connected to the left side of the vertical plate 3, the guide tube 5 and the guide hole 4 are interconnected, providing an initial guide channel for the metal pipe, ensuring that the pipe has a stable direction of travel before entering the guide wheel assembly 7, and an adjustment mechanism 6 is provided inside the mounting groove 2, on which the guide wheel assembly 7 is provided.

[0018] Specifically, the adjustment mechanism 6 includes a first lead screw 601, a second lead screw 602, a threaded plate 603, and a guide rod 604. The first lead screw 601 is rotatably connected to the rear side of the inner wall of the mounting groove 2 via a bearing. The front end of the first lead screw 601 is fixedly connected to the second lead screw 602. The thread direction of the second lead screw 602 is opposite to that of the first lead screw 601. The front end of the second lead screw 602 passes through the mounting groove 2 and the mounting base 1 in sequence and extends to the outside of the mounting base 1 and is fixedly connected to a handle. The second lead screw 602 is movably connected to the mounting base 1. The surfaces of the first lead screw 601 and the second lead screw 602 are both threadedly connected to the threaded plate 603. The threaded plate 603 is movably connected to the mounting groove 2. The front and rear sides of the inner wall of the mounting groove 2 are fixedly connected by two symmetrically arranged guide rods 604, and the threaded plate 603 is slidably sleeved on the guide rod 604. The guide rod not only serves as a fixed support, but also provides precise guidance for the sliding of the threaded plate 603, ensuring the smoothness and accuracy of the movement of the threaded plate 603, thereby achieving precise adjustment of the guide wheel spacing.

[0019] In practical implementation, the guide wheel assembly 7 includes a support shaft 701, a connecting groove 702, a limiting groove 703, a connecting shaft 704, a limiting block 705, a guide wheel 706, a first port 707, a second port 708, a third port 709, a baffle 710, a bolt 711, and a nut 712. The top of the threaded plate 603 is rotatably connected to three support shafts 701 via bearings.

[0020] Specifically, a connecting groove 702 is provided at the top of the support shaft 701, and limiting grooves 703 that communicate with the connecting groove 702 are provided at the top of the support shaft 701 and on both the left and right sides of the connecting groove 702. A connecting shaft 704 is movably inserted into the connecting groove 702.

[0021] In specific implementation, the limiting groove 703 is movably engaged with the limiting block 705, the limiting block 705 is fixedly connected to the connecting shaft 704, the top of the connecting shaft 704 passes through the connecting groove 702 and extends to the outside of the connecting groove 702 and is fixedly connected with the guide wheel 706, and the front side of the support shaft 701 is provided with a first through-hole 707.

[0022] Specifically, the first port 707 is connected to the connecting groove 702, the rear side of the support shaft 701 is provided with a second port 708 that is connected to the connecting groove 702, the surface of the connecting shaft 704 is provided with a third port 709 corresponding to the position of the second port 708, and the front side of the support shaft 701 is movably connected with a baffle 710.

[0023] In specific implementation, a bolt 711 is fixedly connected to the rear side of the baffle 710. The rear end of the bolt 711 passes through the first port 707, the third port 709 and the second port 708 in sequence and extends to the outside of the second port 708. The bolt 711 is movably connected to the first port 707, the second port 708 and the third port 709. A nut 712 is threaded onto the surface of the bolt 711. The front side of the nut 712 abuts against the rear side of the support shaft 701.

[0024] In practical applications: When it is necessary to perform coiling and diameter reduction processing on metal pipes of different specifications, the operator rotates the handle in the forward or reverse direction according to the pipe diameter and wall thickness, driving the second lead screw 602 and the first lead screw 601 to rotate. Since the thread direction of the second lead screw 602 and the first lead screw 601 is opposite, the two threaded plates 603 move towards or away from each other on the guide rod 604, thereby adjusting the distance between the guide wheels 706 to accommodate pipes of different specifications. During the pipe processing, the pipe first enters the guide wheel assembly 7 through the guide tube 5 and the guide hole 4. The guide wheels 706 rotate flexibly under the drive of the pipe, providing precise guidance for the pipe and ensuring the stability and processing accuracy of the pipe during the coiling and diameter reduction process. When the guide wheel 706 needs to be replaced, turn the nut 712 counterclockwise to disengage it from the bolt 711. Then, pull the baffle 710 away from the support shaft 701, thereby disengaging the bolt 711 from the first port 707, the second port 708, and the third port 709. This allows you to remove the baffle 710 and the bolt 711. Then, pull the connecting shaft 704 out of the connecting groove 702, simultaneously disengaging the limiting block 705 from the limiting groove 703. This allows you to remove the guide wheel 706. Next, insert the connecting shaft 704 from the guide wheel 706 to be replaced into the connecting groove 702, and insert the limiting block 705 into the limiting groove 703. Finally, pass the bolt 711 through the first port 707, the third port 709, and the second port 708 in sequence, and lock it in place by engaging the nut 712 with the bolt 711.
