[0002] In the finishing pass of the double rolling mill, before the rolled piece enters the last set of roll passes, in order to ensure that the rolled piece can enter the roll passes accurately and stably and avoid collision, scratch or deviation, a guide device is required to provide final guidance and support for the rolled piece.

[0003] In existing technology, the operator observes intently, and after the tube head flies out from the fixed guide, quickly moves forward and catches the falling tube head with a gloved hand or tool.

[0004] Currently, after the copper tubes are discharged from the rolling mill and rewound, the tube ends, after being bent, generally require manual support before being guided onto the cantilevered support rollers, resulting in high labor intensity. Therefore, this invention provides a rolling mill rewinding guide device to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides a rolling mill coiling guide device, such as... Figure 1-6As shown, the system includes a wall 1. A pair of rotating shafts 11 are installed on one side of the wall 1. A work roller 12 is sleeved at one end of each shaft 11, and a sleeve shaft 13 is sleeved at the other end. A sliding block 14 is sleeved at the middle of one end of each shaft 11. A cylinder 15 is fixedly connected to one side of the wall 1. A guide block 16 is fixedly connected to one end of the cylinder 15. A guide arc 17 is provided inside the guide block 16, and an arc-shaped tube groove 18 is formed within the guide arc 17. During operation, because the copper tube rolling line currently rewinds the tube after it exits, the tube end generally requires manual support after bending. The tube end is guided into the cantilevered support roller. The above method involves high manual labor intensity. By setting the guide arc 16 fixed to the bottom of the curved arc 15 and the cylinder 18 fixed to one end of the curved arc 15, the guide block 16 and the guide arc 17 together form a precise, arc-shaped guiding path. This path simulates the bending force applied to the tube head during manual operation, allowing it to smoothly transition to the winding direction. Before the rolled piece arrives, the cylinder pushes it aside, allowing the tube head to enter easily without precise alignment. After the tube head enters, the cylinder drives it to move backward, wrapping the tube head within the arc groove 18, thus achieving automatic capture.

[0032] like Figure 1 and Figure 2 As shown, a base 2 is provided outside the rotating shaft 11. A groove is provided inside the base 2. A connecting block 1 21 is fixedly connected inside the groove. A rotating rod 22 is rotatably connected inside the connecting block 1 21. Multiple connecting blocks 23 are fixedly connected outside the rotating rod 22. Both ends of the connecting blocks 23 are hinged with tension plates 24. The other end of the tension plates 24 is hinged with a connecting block 3. An expansion plate 25 is fixedly connected to the top of the connecting blocks 3. An auxiliary motor 26 is fixedly connected to the other end of the rotating rod 22. During operation, by setting the tension plates 24 to be connected to the connecting blocks 23 and 3 respectively through hinges, a multi-link mechanism is formed. When the auxiliary motor 26 drives the rotating rod 22 to rotate, the linkage mechanism composed of tension plates 24 can synchronously drive multiple expansion plates 25 to move inward or outward, thereby expanding and reducing the pressure on the steel rope.

[0033] like Figure 6 As shown, a first telescopic frame 3 is fixedly connected to one end of the wall 1, and a second telescopic frame 31 is sleeved inside the first telescopic frame 3. One end of the second telescopic frame 31 is fixedly connected to the guide block 16. During operation, by setting the second telescopic frame 31 to be sleeved inside the first telescopic frame 3, the sleeved structure of the first telescopic frame 3 and the second telescopic frame 31 provides a long-distance and stable cantilever support for the guide block 16, preventing it from shaking or sagging during cylinder driving and operation, and ensuring guiding accuracy.

[0034] like Figure 5As shown, a damping plate 4 is fixed to the inner wall of one end of the groove of the base 2. A spring 41 is fixed to one end of the damping plate 4, and a damping plate 42 is fixed to the other end of the spring 41. During operation, by setting the damping plate 4 and the damping plate 42 to be fixed to the inner wall and end of the groove of the base 2 respectively, and the spring 41 connecting the two, the impact force is transmitted to the base 2 when the high-speed rolling workpiece first hits the expansion plate 25 or the guide arc 17. At this time, the spring 41 will be compressed and deformed, absorbing most of the impact energy and avoiding damage to the precision parts of the equipment by hard collision.

[0035] like Figure 3 As shown, a steel wire rope 5 is provided on the top of the expansion plate 25, and a bearing 51 is fixed to the other end of the steel wire rope 5. The bearing 51 is rotatably connected to the rotating shaft 11. During operation, by setting one end of the steel wire rope 5 to be connected to the expansion plate 25 and the other end to be rotatably connected to the rotating shaft 11 through the bearing 51, the functional integrity of the entire adaptive clamping system during the opening and closing process of the guide unit is ensured.

[0036] like Figure 6 As shown, a base 6 is fixedly connected to one end of the base 2. A groove is provided at one end of the base 6, and a sliding block 61 is slidably connected in the groove. The sliding block 61 is rotatably connected to the rotating shaft 11. During operation, by setting the base 6 to be fixed to one end of the base 2, and the sliding block 61 inside it rotatably connected to the rotating shaft 11, the combination of the sliding block 61 and the base 6 allows for fine adjustment of the overall position of the rotating shaft 11. These two adjustment mechanisms enable the device to accurately align with the exit centerline of the rolling mill and the inlet centerline of the coiler, ensuring that the rolled piece can transition smoothly, which is a prerequisite for stable operation.

[0037] like Figure 6 As shown, a first telescopic frame 3 and a second telescopic frame 31 are respectively fixed to one end of a fixing block 7 and a fixing block 71. One end of the fixing block 7 and the fixing block 71 is respectively fixed to one end of the second telescopic rod 72. During operation, by setting the first telescopic frame 3 and the second telescopic frame 31 to be fixed to one end of a fixing block 7 and a fixing block 71 respectively, it is ensured that the guide block 16 maintains its posture (such as angle) unchanged when pushed or pulled by the first / second telescopic frame, and only performs translational movement, which further ensures the stability and predictability of the guidance.

[0038] As shown in the figure, a guide nozzle 8 is fixedly connected to the bottom of the guide arc 17. During operation, by setting the guide nozzle 8 to be fixedly connected to the bottom of the guide arc 17, a smooth transition curve from horizontal to upward is formed. This curve accurately guides the tube head to change direction, avoiding tube head deformation, scratches or jamming caused by sharp turns or collisions.

[0039] like Figure 2As shown, multiple through holes are provided on both sides of the base 2, and fixing pins 9 are inserted into the through holes. During operation, the fixing pins 9 are inserted into the through holes so that after adjustment, the working position is locked by the fixing pins 9 to prevent the working position from drifting.

[0040] like Figure 4 As shown, a nylon plate 10 is fixedly attached to the bottom of the guide nozzle 8. During operation, by setting the bottom of the guide nozzle 8 to be fixedly attached to the nylon plate 10, the nylon plate 10 serves as a liner that directly contacts the rolled workpiece. It has excellent wear resistance and self-lubricating properties, which greatly reduces the friction coefficient of the rolled workpiece when it runs in the guide groove, and effectively prevents the metal surface from being scratched or abraded.

[0041] Working Principle: Currently, after the copper tubes exit the rolling line, they are wound upwards. After bending, the tube ends generally require manual support before being guided onto the cantilevered support rollers. This process is labor-intensive. By setting up a guide arc 16 fixed to the bottom of the bending arc 15, and a cylinder 18 fixed to one end of the bending arc 15, the guide block 16 and the guide arc 17 together form a precise, arc-shaped guiding path. This path simulates the bending force applied to the tube end during manual operation, allowing it to smoothly transition to the winding direction. Before the rolled piece arrives, the cylinder pushes it aside, allowing the tube end to easily... The tube head enters easily without precise alignment. After the tube head enters, the cylinder drives it to move backward, wrapping the tube head within the arc-shaped tube groove 18, achieving automatic capture. A tension plate 24 is connected to connecting block 23 and connecting block 3 via hinges, forming a multi-link mechanism. This allows multiple expansion plates 25 to move inward or outward simultaneously when the auxiliary motor 26 drives the rotating rod 22, through the linkage mechanism of the tension plate 24, thus expanding and reducing the pressure on the steel rope. A second expansion frame 31 is fitted inside the first telescopic frame 3, providing long-distance, stable cantilever support for the guide block 16, preventing it from swaying during cylinder drive and operation. The system is designed to ensure guiding accuracy by sag. Shock-absorbing plates 4 and 42 are fixed to the inner wall and end of the groove in the base 2, respectively, with a spring 41 connecting them. This ensures that when the high-speed rolling stock first impacts the expansion plate 25 or the guide arc 17, the impact force is transmitted to the base 2. At this time, the spring 41 compresses and deforms, absorbing most of the impact energy and preventing damage to the precision components of the equipment from a hard collision. A steel wire rope 5 is connected at one end to the expansion plate 25 and at the other end to the rotating shaft 11 via a bearing 51, ensuring the functional integrity of the entire adaptive clamping system during the opening and closing of the guiding unit. A base 6 is fixed to one end of the base 2, and its internal sliding block 61 rotates with the rotating shaft 11. The combination of sliding block 61 and base 6 allows for fine-tuning of the overall position of the rotating shaft 11. These two adjustment mechanisms enable the device to precisely align with the exit centerline of the mill and the inlet centerline of the coiler, ensuring a smooth transition of the rolled piece. This is a prerequisite for stable operation. By fixing one block 7 and fixing two blocks 71 to one end of the first telescopic frame 3 and the second telescopic frame 31 respectively, the guide block 16 maintains its posture (such as angle) unchanged when pushed or pulled by the first / second telescopic frame, only performing translational movement. This further ensures the stability and predictability of the guidance. By fixing a guide nozzle 8 to the bottom of the guide arc 17, a smooth transition curve from horizontal to upward coiling is formed.This curve precisely guides the tube head to change direction, avoiding deformation, scratches, or jamming caused by sharp turns or collisions. A fixing pin 9 inserted into the through hole locks the tube head in place after adjustment, preventing position drift. A nylon plate 10 is fixed to the bottom of the guide nozzle 8, serving as a liner in direct contact with the workpiece. This nylon plate possesses excellent wear resistance and self-lubricating properties, significantly reducing the coefficient of friction as the workpiece runs within the guide groove, effectively preventing scratches and abrasions on the metal surface.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
