Description

Technical Field

[0001] This invention belongs to the field of cables, specifically a high-precision roundness correction device for armored cables. Background Technology

[0002] Armored cables are cables with an added armor layer in their structure. The armor layer is usually made of metallic materials (such as steel strip, steel wire, aluminum, etc.) or non-metallic materials (such as polymers) to enhance the mechanical and protective properties of the cable.

[0003] Cable roundness refers to the degree to which the shape of the cable cross-section is close to a circle. Good cable roundness results in more stable mechanical properties, and it is less likely to be twisted or deformed during laying. Good roundness can reduce stress concentration inside the cable and avoid uneven electric field distribution caused by irregular shape, thereby improving the electrical performance of the cable.

[0004] Traditional cable roundness correction structures are relatively simple, often using a ring of the same thickness as the cable to be fitted onto the outside of the main ring. As the cable passes through, it is squeezed and corrected. This structure not only cannot be adapted to the cable material, leading to damage to the cable during the correction process, but also the correction force is too direct, which can easily result in a lower roundness of the cable after correction.

[0005] Therefore, the present invention provides a high-precision roundness correction device for armored cables. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a high-precision roundness correction device for armored cables, comprising a rotatable movable ring, multiple connecting arms fixedly connected to the outer side of the movable ring, an electric telescopic rod fixedly connected to the end of each connecting arm, multiple spring telescopic rods fixedly connected to the end of each electric telescopic rod, the multiple spring telescopic rods being arranged in parallel, a connecting platform installed between the ends of the multiple spring telescopic rods, a correction roller rotatably connected to the middle of the connecting platform, a drive motor fixedly connected to one side of the connecting platform, an eccentric roller mounted biased to one side of the middle of the correction roller, the eccentric roller being fixedly connected to the output end of the drive motor, two detection arms provided at the front end of the movable ring, a circular detection hole formed between the two detection arms, and a detection pad for detecting the roundness of the cable surface installed on the outer side of the detection arm;

[0008] After the cable, wrapped with armor, is passed through the moving ring, and multiple electrically operated telescopic rods extend to place the straightening roller against the cable surface. The drive motor is then activated to rotate the straightening roller. Because the eccentric roller and the straightening roller are eccentrically connected, the straightening roller continuously impacts and squeezes the outer surface of the cable during rotation. As the rotation speed increases, the straightening roller achieves a high-frequency vibration smoothing function on the cable surface. Simultaneously, the spring telescopic rods ensure that the straightening roller has a certain degree of rebound during the impact smoothing process, thus preventing excessive inward squeezing of the cable surface. Furthermore, adjustments can be made as needed. The extension range of the electric telescopic rod is controlled. A greater extension range results in a stronger reaction force from the spring telescopic rod onto the straightening rollers, thus accommodating harder armor layers and cables, and vice versa. Simultaneously, as the moving ring rotates, it drives the straightening rollers to rotate on the outside of the cable. As the cable moves forward, multiple straightening rollers perform a spiral pressing and smoothing process on the cable surface. Increasing the rotation speed enhances the straightening and smoothing effect. Before passing through the moving ring, the cable passes through the detection arm, using two detectors... The arm wraps around the cable, and the wrapping force does not affect the normal movement of the cable. The detection arm can be replaced with one of the same arc diameter according to the cable diameter. As the cable passes through the detection hole formed by the detection arm, it will be squeezed against the detection pad. The inner ring of the detection arm is equipped with multiple press-type pressure sensors, which are wrapped by the detection pad. When the armor layer on the outer surface of the cable is uneven, it will squeeze the detection pad and pressure sensors. Based on the detected information, the extension length of the electric telescopic rod, the speed of the straightening roller, and the speed of the moving ring are increased, thereby increasing the effect of smoothing the cable surface. Conversely, the performance can be reduced to decrease the energy consumption of the equipment. Through this setting, it is ensured that after the cable passes through the moving ring, the cross-section of the cable is straightened to a near-perfect circle, so that the roundness of the cable meets the qualified standard. At the same time, the overall device operates stably, and the whole process is fully automated. It can perform straightening work for a long time during the cable production and armoring process. It can also adjust the straightening intensity according to the cable material to adapt to more types of cable straightening work. At the same time, it can increase the straightening force according to different surface conditions of the cable, so that the device can straighten the cable with the best roundness according to different surface conditions.

[0009] Preferably, a restraining ring is provided on the outer side of the moving ring, and an annular moving groove is opened on the outer side of the restraining ring. The moving ring is slidably engaged in the moving groove. Two symmetrically arranged electric wheels are installed on the outer side of the restraining ring near the front end. The electric wheels are movably fitted with the outer side of the moving ring. The moving ring is fixed by the restraining ring. Then, the rotation of the electric wheels drives the annular movement of the moving ring, thereby driving multiple electric telescopic rods and straightening rollers to straighten the cable.

[0010] Preferably, the rear end of the moving ring is provided with multiple rotatable friction discs. The multiple friction discs are arranged in a ring at equal intervals, and circular friction holes are formed between the multiple friction discs. After the cable is corrected by the straightening roller, it will finally pass through the friction holes formed by the multiple friction discs. Since the armor layer of the armored cable is basically spirally wound on the outside of the cable insulation layer, such as steel wire armor, aluminum tape armor, etc., the multiple friction discs are attached to the outside of the armor layer and rotate. This can make the armor layer, which was originally slightly loose after being impacted and corrected by the straightening roller, tightly wrap around the outside of the cable again. The friction discs continuously slide and rub against the outside of the armor layer. It is necessary to ensure that the rotation direction is the same as the direction of armor wrapping. In this way, under the friction and rotation of the friction discs, the cable can be guaranteed to have a sufficiently large roundness, and the armor layer can also be tightly wrapped.

[0011] Preferably, a rotating disk is installed at the end of the spring telescopic rod between the connecting platform and the connecting platform. The rotating disk consists of two discs that rotate and engage with each other. The two discs are fixedly connected to the electric telescopic rod and the connecting platform, respectively. By setting the rotating disk, the angle of the connecting platform can be adjusted, thereby adjusting the friction angle between the straightening roller and the cable. Different angles can be adapted to the spiral packaging curvature of the armor layer, thereby adapting to the armor layer of different types of packages.

[0012] Preferably, the front end of the restraint ring is equipped with two support arms, and the end of each support arm is vertically fixed to a horizontally arranged adjusting telescopic rod. The end of the adjusting telescopic rod is fixed to the outside of the probe arm. The adjusting telescopic rod is fixed by the support arms, and the adjusting telescopic rod can control the opening and closing of the two probe arms. Different models of probe arms can be replaced to adapt to cables of different diameters.

[0013] Preferably, a gear ring 1 is fixedly connected between the outer sides of the plurality of electric telescopic rods, and a gear ring 2 is arranged parallel to the rear end of the gear ring 1. The gear ring 1 and gear ring 2 are connected by a plurality of gear sets. A plurality of adjusting telescopic rods 2 are fixedly connected to the rear end of the gear ring 2, and the ends of the adjusting telescopic rods 2 are fixedly connected to the friction discs. When the moving ring rotates, it will drive the electric telescopic rods and gear ring 1 to rotate. Gear ring 1 drives gear ring 2 to rotate, which in turn drives the plurality of friction discs to rotate. In this way, it is not necessary to install additional drive parts for gear ring 2. At the same time, gear ring 1 can be detached from the electric telescopic rod and can be used independently when gear sets are not needed.

[0014] Preferably, the gear set consists of a large gear and a small gear meshing with each other. The large gear meshes with gear ring one, and the small gear meshes with gear ring two. Multiple gear sets are arranged in a ring at equal intervals. Through the meshing of the large gear and the small gear in the gear set, the rotational speed of gear ring two after transmission is greater than that of gear ring one, thereby achieving the high-speed rotation effect of multiple friction discs, which can ensure that the armor layer is tightly wrapped on the cable.

[0015] Preferably, a protective frame is fitted around the outer side of the first gear ring and the second gear ring, and a support platform is provided on the outer side of the gear set for protecting and fixing the position of the gear set. The bottom of the protective frame and the restraining ring are both fixed with a base. The protective frame reduces the influence of the outside on the first gear ring and the second gear ring, and the base is used to raise the restraining ring and the protective frame to ensure the normal operation of other parts.

[0016] Preferably, the inner ring of the restraining ring is equipped with multiple auxiliary wheels, which are movably fitted to the outer side of the moving ring. Both the front and rear ends of the moving ring are fixed with annular protrusions. The restraining ring is held in place by the auxiliary wheels and the electric wheel, ensuring the stability of the moving ring during rotation. The protrusions can increase the contact surface between the moving ring and the restraining ring, further increasing the connection stability.

[0017] Preferably, the straightening roller has a vibration groove inside, and the top of both the moving ring and the binding ring has a notch, the length of which is less than one-quarter of the length of the main ring. The notch allows the device to be installed on any normally operating cable production equipment. The cable is placed from above the moving ring to the center position. Note that in this state, the gear ring needs to be removed. Metal balls can be added to the vibration groove to increase the impact force and smoothing effect of the straightening roller.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The high-precision roundness correction device for armored cables described in this invention, through the arrangement of a moving ring, a correction roller, and a detection arm, ensures that after the cable passes through the moving ring, the cross-section of the cable is corrected to a near-perfect circle, allowing the cable's roundness to meet the qualified standard. Simultaneously, the entire device operates stably, and the entire process is fully automated. It can perform correction work continuously during cable production and armoring processes. Furthermore, the correction intensity can be adjusted according to the cable material to adapt to various cable correction tasks. Additionally, the correction force can be increased based on different cable surface conditions, enabling the device to correct cables with optimal roundness according to different surface conditions.

[0020] 2. The high-precision roundness correction device for armored cables described in this invention, after the cable passes through the correction roller, it will finally pass through the friction holes formed by multiple friction discs. Since the armor layer of the armored cable is basically spirally wound on the outside of the cable insulation layer, such as steel wire armor, aluminum tape armor, etc., the multiple friction discs are attached to the outside of the armor layer and rotate. This can make the armor layer, which was originally slightly loose after being impacted and corrected by the correction roller, tightly wrap around the outside of the cable again. The friction discs continuously slide and rub against the outside of the armor layer. It is necessary to ensure that the rotation direction is the same as the direction of armor wrapping. In this way, under the friction and rotation of the friction discs, the cable can be guaranteed to have a sufficiently large roundness, and the armor layer can also be tightly wrapped.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 8As shown in the embodiment of the present invention, a high-precision roundness correction device for armored cables includes a rotatable movable ring 2. Multiple connecting arms 11 are fixedly connected to the outer side of the movable ring 2. An electric telescopic rod 10 is fixedly connected to the end of each connecting arm 11. Multiple spring telescopic rods 15 are fixedly connected to the end of each electric telescopic rod 10. The multiple spring telescopic rods 15 are arranged in parallel. A connecting platform 13 is installed between the ends of the multiple spring telescopic rods 15. A correction roller 12 is rotatably connected to the middle of the connecting platform 13. A drive motor is fixedly connected to one side of the connecting platform 13. An eccentric roller 17 is installed biased to one side of the middle of the correction roller 12. The eccentric roller 17 is fixedly connected to the output end of the drive motor. Two detection arms 7 are provided at the front end of the movable ring 2, forming a circular detection hole between the two detection arms 7. A detection pad 19 for detecting the roundness of the cable surface is installed on the outer side of each detection arm 7.

[0033] After the cable with the armor layer is wrapped, it is passed through the moving ring 2. Multiple electric telescopic rods 10 are extended, pressing the straightening roller 12 against the cable surface. The drive motor is started to rotate the straightening roller 12. Because the eccentric roller 17 and the straightening roller 12 are eccentrically connected, the straightening roller 12 continuously impacts and squeezes the outer surface of the cable during rotation. As the rotation speed increases, the straightening roller 12 can achieve a high-frequency vibration smoothing function on the cable surface. Simultaneously, the spring telescopic rod 15 ensures that the straightening roller 12 has a certain rebound capability during the impact smoothing process, thus preventing excessive inward squeezing of the cable surface. Furthermore, the speed can be controlled as needed. The extension range of the electric telescopic rod 10 is controlled. The greater the extension range of the electric telescopic rod 10, the greater the reaction force of the spring telescopic rod 15 on the straightening roller 12, thus corresponding to armor layers and cables with greater hardness, and vice versa. Simultaneously, as the moving ring 2 rotates, it drives the straightening roller 12 to rotate on the outside of the cable. As the cable moves forward, multiple straightening rollers 12 can perform spiral compression and smoothing work on the surface of the cable. Increasing the rotation speed can enhance the straightening and smoothing effect. Before passing through the moving ring 2, the cable passes through the detection arm 7, and the two detection arms 7 wrap around the cable. The wrapping force does not affect the normal movement of the cable. The detection arm 7 can be replaced with a detection arm 7 of the same arc according to the cable diameter. As the cable passes through the detection hole formed by the detection arm 7, it will be squeezed against the detection pad 19. The inner ring of the detection arm 7 is equipped with multiple press-type pressure sensors, which are wrapped by the detection pad 19. The press-type pressure sensors have a large multiplier and will shorten when compressed, without applying pressure to the surface of the cable. When the armor layer on the outer surface of the cable is uneven, it will squeeze the detection pad 19 and the pressure sensor. Based on the detected information, the extension length of the electric telescopic rod 10, the rotation speed of the straightening roller 12, and the movement ring are increased. The rotation speed of the ring is increased to improve the smoothing effect on the cable surface, while a decrease in rotation speed can reduce the performance and energy consumption of the equipment. This setting ensures that after the cable passes through the moving ring 2, the cross-section of the cable is corrected to a near-perfect circle, achieving the required roundness. The entire device operates stably, and the entire process is fully automated. It can perform correction work for extended periods during cable production and armoring. The correction intensity can be adjusted according to the cable material to adapt to various cable correction tasks. Furthermore, the correction force can be increased based on different surface conditions of the cable, allowing the device to correct cables with optimal roundness according to different surface conditions.

[0034] A restraining ring 1 is provided on the outer side of the moving ring 2. An annular moving groove 14 is provided on the outer side of the restraining ring 1. The moving ring 2 is slidably engaged in the moving groove 14. Two symmetrically arranged electric wheels 8 are installed on the outer side of the restraining ring 1 near the front end. The electric wheels 8 are in movable contact with the outer side of the moving ring 2.

[0035] During operation, the moving ring 2 is fixed by the clamping ring 1, and then the rotation of the electric wheel 8 drives the moving ring 2 to move in a ring, thereby driving multiple electric telescopic rods 10 and straightening rollers 12 to straighten the cable.

[0036] The rear end of the moving ring 2 is provided with a plurality of rotatable friction discs 25, which are arranged in a ring at equal intervals, and circular friction holes are formed between the plurality of friction discs 25.

[0037] During operation, after the cable is straightened by the straightening roller 12, it will eventually pass through the friction holes formed by multiple friction discs 25. Since the armor layer of armored cables is basically spirally wound on the outside of the cable insulation layer, such as steel wire armor and aluminum tape armor, the multiple friction discs 25 are attached to the outside of the armor layer and rotate. This can make the armor layer, which was originally slightly loose after being impacted and straightened by the straightening roller 12, tightly wrap around the outside of the cable again. The friction discs 25 continuously slide and rub against the outside of the armor layer. It is necessary to ensure that the rotation direction is the same as the direction of armor wrapping. In this way, under the friction and rotation of the friction discs 25, the cable can have a sufficiently large roundness, and the armor layer can also be tightly wrapped.

[0038] A rotating disk 16 is installed at the end of the spring telescopic rod 15 between the connecting platform 13. The rotating disk 16 is composed of two disks that rotate and engage with each other. The two disks are respectively fixed to the electric telescopic rod 10 and the connecting platform 13.

[0039] During operation, the angle of the connecting table 13 can be adjusted by rotating the disk 16, thereby adjusting the friction angle between the straightening roller 12 and the cable. Different angles can adapt to the spiral packaging curvature of the armor layer, thus adapting to the armor layer of different types of packages.

[0040] The front end of the restraint ring 1 is equipped with two support arms 5. The ends of the support arms 5 are vertically fixed to a horizontally arranged adjusting telescopic rod 6. The ends of the adjusting telescopic rod 6 are fixed to the outside of the probe arm 7.

[0041] During operation, the telescopic rod 6 is fixed and adjusted by the support arm 5. Adjusting the telescopic rod 6 can control the opening and closing of the two probe arms 7. Different models of probe arms 7 can be replaced to adapt to cables of different diameters.

[0042] A gear ring 20 is fixedly connected between the outer sides of the plurality of electric telescopic rods 10. A gear ring 21 is arranged parallel to the rear end of the gear ring 20. The gear ring 20 and the gear ring 21 are connected by a plurality of gear sets 22. A plurality of adjusting telescopic rods 24 are fixedly connected to the rear end of the gear ring 21. The end of the adjusting telescopic rod 24 is fixedly connected to the friction disc 25.

[0043] During operation, the rotation of the moving ring 2 will drive the electric telescopic rod 10 and the gear ring 20 to rotate. The gear ring 20 drives the gear ring 21 to rotate, which in turn drives the multiple friction discs 25 to rotate. This eliminates the need to install additional drive parts on the gear ring 21. At the same time, the gear ring 20 can be detached from the electric telescopic rod 10 and can be used independently when the gear set 22 is not needed.

[0044] The gear set 22 is composed of a large gear 27 and a small gear 26 meshing with each other. The large gear 27 meshes with a gear ring 20, and the small gear 26 meshes with a gear ring 21. Multiple gear sets 22 are arranged in a ring at equal intervals.

[0045] During operation, the meshing of the large gear 27 and the small gear 26 in the gear set 22 allows the gear ring 21 after transmission to rotate at a speed greater than that of the gear ring 20, thereby achieving the high-speed rotation effect of multiple friction discs 25, which can ensure that the armor layer is tightly wrapped around the cable.

[0046] A protective frame 3 is sleeved on the outer side of the first gear ring 20 and the second gear ring 21. A support platform 23 for protecting and fixing the position of the gear set 22 is provided on the outer side of the gear set 22. A base 4 is fixedly connected to the bottom of the protective frame 3 and the binding ring 1.

[0047] During operation, the protective frame 3 reduces the impact of external factors on gear ring 1 20 and gear ring 2 21, while the base 4 is used to raise the restraint ring 1 and the protective frame 3 to ensure the normal operation of other parts.

[0048] The inner ring of the restraint ring 1 is equipped with a plurality of auxiliary wheels 9, the auxiliary wheels 9 are movably fitted with the outer side of the moving ring 2, and the front and rear ends of the moving ring 2 are fixed with annular protrusions.

[0049] During operation, the auxiliary wheel 9 and the electric wheel 8 hold the restraining ring 1 in place, ensuring the stability of the moving ring 2 during rotation. The convex strip increases the contact area between the moving ring 2 and the restraining ring 1, further enhancing the connection stability.

[0050] The correcting roller 12 has a vibration groove 18 inside, and the top of the moving ring 2 and the binding ring 1 both have notches, and the length of the notches is less than one-quarter of the length of the main ring.

[0051] During operation, the notch setting allows the device to be installed on any normally operating cable production equipment. The cable is placed from above the moving ring 2 to the center position. Note that in this state, the gear ring 20 needs to be removed. Metal balls can be added to the vibration groove 18 to increase the impact force and smoothing effect of the straightening roller 12.

[0052] During operation, the cable, after being wrapped with armor, is passed through the moving ring 2. Multiple electric telescopic rods 10 are extended, pressing the straightening roller 12 against the cable surface. The drive motor is then activated, causing the straightening roller 12 to rotate. Because the eccentric roller 17 and the straightening roller 12 are eccentrically connected, the straightening roller 12 continuously impacts and squeezes the outer surface of the cable during rotation. As the rotation speed increases, the straightening roller 12 achieves a high-frequency vibration smoothing function on the cable surface. Simultaneously, the spring telescopic rod 15 ensures that the straightening roller 12 has a certain rebound capability during the impact smoothing process, thus preventing the cable surface from being excessively squeezed inwards. The electric telescopic rod 10 can be extended as needed. A greater extension of the electric telescopic rod 10 results in a greater reaction force from the spring telescopic rod 15 on the straightening roller 12, thus accommodating armor layers and cables with higher hardness, and vice versa. Simultaneously, as the moving ring 2 rotates, it drives the straightening roller 12 to rotate on the outside of the cable. As the cable moves forward, multiple straightening rollers 12 perform spiral pressing and smoothing on the cable surface. Increasing the rotation speed enhances the straightening and smoothing effect. Before passing through the moving ring 2, the cable must first pass through... The detection arms 7, consisting of two arms, wrap around the cable. The wrapping force does not affect the normal movement of the cable. The detection arms 7 are replaceable, with arms of the same curvature as the cable diameter. As the cable passes through the detection holes formed by the detection arms 7, it is compressed against the detection pad 19. Multiple press-type pressure sensors are installed on the inner ring of the detection arms 7, and these sensors are wrapped by the detection pad 19. When the armor layer on the outer surface of the cable is uneven, it will compress the detection pad 19 and the pressure sensors. Based on the detected information, the extension length of the electric telescopic rod 10, the rotation speed of the straightening roller 12, and the rotation speed of the moving ring 2 are increased, thereby increasing... The effect of smoothing the cable surface can be improved, while the effect of reducing surface roughness can lower performance indicators and reduce equipment energy consumption. This design ensures that after the cable passes through the moving ring 2, the cross-section of the cable is corrected to a near-perfect circle, achieving the required roundness standard. The entire device operates stably, and the entire process is fully automated. It can perform correction work continuously during cable production and armoring. The correction intensity can be adjusted according to the cable material to adapt to various cable correction tasks. Furthermore, the correction force can be increased based on different cable surface conditions, allowing the device to correct cables with optimal roundness according to varying surface conditions.

[0053] The moving ring 2 is fixed by the clamping ring 1, and then the rotation of the electric wheel 8 drives the moving ring 2 to move in a ring, thereby driving the multiple electric telescopic rods 10 and the straightening rollers 12 to straighten the cable.

[0054] After the cable passes through the straightening roller 12, it will eventually pass through the friction holes formed by multiple friction discs 25. Since the armor layer of the armored cable is basically spirally wound on the outside of the cable insulation layer, such as steel wire armor, aluminum tape armor, etc., the multiple friction discs 25 are attached to the outside of the armor layer and rotate. This can make the armor layer, which was originally slightly loose after being impacted and straightened by the straightening roller 12, tightly wrap around the outside of the cable again. The friction discs 25 continuously slide and rub against the outside of the armor layer. It is necessary to ensure that the rotation direction is the same as the direction of armor wrapping. In this way, under the friction and rotation of the friction discs 25, the cable can have a sufficiently large roundness, and the armor layer can also be tightly wrapped.

[0055] The angle of the connecting table 13 can be adjusted by setting the rotating disk 16, thereby adjusting the friction angle between the straightening roller 12 and the cable. Different angles can adapt to the spiral packaging curvature of the armor layer, thus adapting to the armor layer of different types of packages.

[0056] The telescopic rod 6 is fixed and adjusted by the support arm 5. Adjusting the telescopic rod 6 can control the opening and closing of the two probe arms 7. Different models of probe arms 7 can be replaced to adapt to cables of different diameters.

[0057] When the moving ring 2 rotates, it will drive the electric telescopic rod 10 and the gear ring 20 to rotate. The gear ring 20 drives the gear ring 21 to rotate, which in turn drives the multiple friction discs 25 to rotate. This eliminates the need to install additional drive parts on the gear ring 21. At the same time, the gear ring 20 can be detached from the electric telescopic rod 10 and can be used independently when the gear set 22 is not needed.

[0058] Through the meshing of the large gear 27 and the small gear 26 in the gear set 22, the rotational speed of the gear ring 21 after transmission is greater than that of the gear ring 20, thereby achieving the high-speed rotation effect of multiple friction discs 25, which can ensure that the armor layer is tightly wrapped on the cable.

[0059] The protective frame 3 reduces the impact of external factors on gear ring 1 20 and gear ring 2 21, and the base 4 is used to raise the restraint ring 1 and the protective frame 3 to ensure the normal operation of other parts.

[0060] The auxiliary wheel 9 and the electric wheel 8 are used to hold the restraining ring 1 in place, ensuring the stability of the moving ring 2 during rotation. The convex strip can increase the contact surface between the moving ring 2 and the restraining ring 1, further increasing the connection stability.

[0061] The notch allows the device to be installed on any working cable production equipment. The cable is placed from above the moving ring 2 to the center position. Note that the gear ring 20 needs to be removed in this state. Metal balls can be added to the vibration groove 18 to increase the impact force and smoothing effect of the straightening roller 12.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
