A flexible cable straightening and shaping device

Abstract

This invention provides a flexible cable straightening and shaping device, relating to the technical field of cable straightening and shaping equipment. It includes a straightening module comprising an installation mechanism, a gradual positioning mechanism, a pressure mechanism, and a control mechanism. The straightening module employs a gradual pressure straightening method, applying straightening and shaping forces to the cable sequentially through pressure modules with progressively increasing pressure. This avoids the problem of surface extrusion damage and internal core wire deformation caused by sudden pressure application during the initial straightening and shaping process. Furthermore, the gradual pressure curves between the pressure modules can be freely adjusted, and the pressure of a single pressure module can be independently controlled during straightening. This solves the problem that cable straightening and shaping devices lack the function of gradual pressure straightening, which makes the cable prone to surface extrusion damage and internal core wire deformation due to sudden application of constant pressure during the initial straightening and shaping process.

Description

Technical Field

[0001] This invention relates to the field of cable straightening and shaping equipment technology, and in particular to a flexible cable straightening and shaping device. Background Technology

[0002] During production, transportation, and storage, flexible cables are prone to bending, twisting, and irregular shapes due to their flexibility and external forces. To ensure the smooth progress of subsequent cutting, connection, and assembly processes, guarantee installation accuracy, maintain signal transmission stability or power transmission reliability, meet the requirements of applications such as precision equipment and automated production lines, and ensure the safety and stability of overall equipment operation, it is necessary to straighten and shape the flexible cables. For example, patent application number CN201810849861.5 discloses a straightening device for large-diameter cables, including a frame. The frame is sequentially equipped with a first straightening mechanism, a second straightening mechanism, a third straightening mechanism, and a fourth straightening mechanism for straightening the cable. The first straightening mechanism is a straightening box with a conical through hole. A bending detection mechanism is provided at the cable outlet of the straightening box. The second straightening mechanism includes a motor and two sets of airflow straightening devices driven by the motor and symmetrically arranged on the frame. Through the four-stage straightening process involving the first, second, third, and fourth straightening mechanisms, straightening is completed during the cable's journey, avoiding the damage caused to the cable by forced straightening in existing technologies.

[0003] In actual use, the clamping force of the existing cable straightening and shaping devices is usually set to a constant value, and they do not have the function of gradual pressure straightening. This makes the cable prone to damage from sudden constant pressure in the early stage of straightening and shaping, resulting in problems such as exfoliation and internal core wire deformation and damage. The stability is poor and the practicality is not high. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please refer to Figures 1 to 10 Example 1: This invention proposes a flexible cable straightening and shaping device, comprising: a straightening body 1, wherein the straightening body 1 is sequentially arranged with a straightening module, a constant temperature shaping module 6, a monitoring module 7, and a cooling module 8 along the cable conveying direction; the straightening module includes an installation mechanism 2, at least three sets of gradual positioning mechanisms 3 evenly distributed along the circumference of the cable, and multiple sets of pressure modules arranged sequentially along the cable conveying direction, each pressure module including a pressure mechanism 4 and a control mechanism 5; the installation mechanism 2 includes an input seat 201 and a control motor 202, the input seat 201 being fixedly installed on the top of the straightening body 1, and the control motor 202 being fixedly installed on the side of the input seat 201; the gradual positioning mechanism 3 includes a positioning rod 301, a positioning seat 302, and a pressure inclined rod 30. 3. The positioning rod 301 is rotatably connected to the inside of the input seat 201. The positioning seat 302 is slidably inserted into the inside of the input seat 201 along the radial direction of the cable. The positioning rod 301 and the positioning seat 302 are in a transmission cooperation to drive the positioning seat 302 to slide. One end of the pressure inclined rod 303 is rotatably connected to the inside of the input seat 201. The side of the positioning seat 302 is provided with a control rod 3021. The inside of the pressure inclined rod 303 is provided with a control groove 3031 extending along its length. The control rod 3021 is inserted into the end of the control groove 3031 away from the rotating shaft of the pressure inclined rod 303. The pressure inclined rod 303 is inclined towards the cable conveying direction. Multiple pressure mechanisms 4 are all connected to the control groove 3031 of the corresponding gradual positioning mechanism 3 through the linkage rod 4021. The pressure mechanism 4 includes a pressure column 401, a positioning plate 402, a pressure plate 403, and a pressure spring 4031. The pressure column 401 is slidably inserted into the input seat 201 along the radial direction of the cable. A straightening wheel 4011 is rotatably connected to the end of the pressure column 401 facing the cable. The positioning plate 402 and the pressure plate 403 are both sleeved on the outside of the pressure column 401, and the pressure plate 403 is located on the side of the positioning plate 402 facing the cable. The linkage rod 4021 is fixedly connected to the side of the positioning plate 402 and inserted into the control slot 3031. The two ends of the pressure spring 4031 abut against the pressure plate 403 and the pressure column 401, respectively. The control mechanism 5 is used for independent adjustment of the straightening and shaping pressure of a single pressure module. The control mechanism 5 includes a retainer 501, a single-control coupling 502, an electromagnet 503, and a linkage gear 504. The retainer 501 is slidably inserted into the inside of the input seat 201 along the radial direction of the cable. The single-control coupling 502 is rotatably connected to the top of the retainer 501. The electromagnet 503 is fixedly installed inside the input seat 201. The linkage gear 504 is rotatably connected to the inside of the input seat 201. The top of the retainer 501 is provided with a magnetic block 5011 that cooperates with the electromagnet 503. After the electromagnet 503 is energized, it drives the retainer 501 to move by attracting the magnetic block 5011, so as to drive the single-control coupling 502 to connect or disconnect from the linkage gear 504.

[0031] The gradual positioning mechanism 3 is provided in three sets, with an included angle of 120 degrees between adjacent sets. During use, when the cable passes through the alignment module, it will be subjected to the pressure straightening and shaping action of the pressure module. The control groove 3031 of the pressure inclined rod 303 can position the positioning plate 402 through the linkage rod 4021, thereby fixing the position of the positioning plate 402. The integral screw 404 integrates the positioning plate 402 and the pressure plate 403 into a whole, so that the pressure plate 403 can provide stable support for the pressure top spring 4031 and transmit the elastic force of the pressure top spring 4031 to the pressure column 401 and the straightening wheel 4011 at its bottom. Thus, when the cable passes through the alignment module, the straightening wheel 4011 can apply the force. The cable is straightened and shaped using this method, which is convenient and flexible. Since the pressure bar 303 is inclined inside the input seat 201, the positioning plates 402 of the multiple pressure modules arranged along its long side are also arranged in an inclined manner. The change in the position of the positioning plates 402 changes the force exerted by the pressure spring 4031 on the pressure column 401 and the straightening wheel 4011, i.e., the pressure during straightening and shaping. Thus, the sequentially inclined positioning plates 402 can achieve a gradual increase in the straightening and shaping pressure of the multiple pressure modules in the cable conveying direction, thereby realizing a gradual pressure straightening method for the cable. This can effectively avoid the phenomenon of damage caused by the large straightening pressure when the cable first enters the input seat 201.

[0032] The mounting mechanism 2 also includes a synchronous gear ring 203. A drive gear 2021 is fixed externally to the shaft of the control motor 202, and a synchronous gear 3011 is fixed to the bottom of the positioning rod 301. Both the synchronous gear 3011 and the drive gear 2021 mesh with the gear teeth on the side of the synchronous gear ring 203 for transmission. In use, the gradual pressure curve between the pressure modules can be freely adjusted. The function of adjusting the gradual pressure curve can be realized by controlling the motor 202. When the control motor 202 rotates, the drive gear 2021 can drive the synchronous gear ring 203 to rotate. When the synchronous gear ring 203 rotates, it can drive the positioning rod 301 to rotate via the synchronous gear 3011. The positioning rod 301 has an external thread on its outer surface, and the positioning seat 302 has a threaded hole inside. The positioning rod 301 is screwed into the positioning seat 302 through the engagement of the external thread and the threaded hole. When the positioning rod 301 rotates, it can drive the positioning seat 302 to move up and down inside the input seat 201 via the thread on its body. When the positioning seat 302 moves, the control rod 3021 can drive the pressure inclined rod 303 to rotate via the control groove 3031, thereby changing the position of the positioning rod 301. The inclination of the pressure bar 303 is adjusted, which changes the position of the multiple pressure module positioning discs 402 arranged along its long side, thus altering the gradual pressure curve. This allows for the adaptation to straightening and shaping operations on cables of different types and specifications, demonstrating strong adaptability. A separation spring 5012 is located at the bottom of the retainer 501. During this process, the two ends of the separation spring 5012 are fixedly connected to the bottom of the retainer 501 and the interior of the input seat 201, respectively. A clutch gear 5022 is fixed to the top of the single-control coupling 502, enabling linkage. The bottom of gear 504 is provided with a clutch tooth groove 5041 that is adapted to the clutch gear 5022. When the electromagnet 503 is energized, the clutch gear 5022 is inserted into the clutch tooth groove 5041, realizing the transmission connection between the single control coupling 502 and the linkage gear 504. Since the electromagnet 503 is not energized, the clutch gear 5022 is disengaged from the clutch tooth groove 5041 under the action of the separation spring 5012. Thus, the pressure mechanism 4 will not change the use state of the control mechanism 5 during adjustment, nor will it jam the device, thereby improving the adaptability of the device.

[0033] The gradual positioning mechanism 3 also includes a single-control motor 304 and a linkage shaft 305. The single-control motor 304 is fixedly installed on the side of the input seat 201, and the linkage shaft 305 is rotatably connected to the inside of the input seat 201. The rotating shaft of the single-control motor 304 is connected to one end of the linkage shaft 305. A linkage gear 3051 is fixed to the outside of the linkage shaft 305, and the linkage gear 3051 meshes with the gear teeth of the linkage gear 504 for transmission. The pressure mechanism 4 also includes an integral screw 404 and a connecting rod 405. The integral screw 404 is rotatably connected to the inside of the positioning disk 402, and the rod body of the integral screw 404 is screwed to the inside of the pressure disk 403 through an external thread. The connecting rod 405 is rotatably connected to the inside of the input seat 201. The two ends of the connecting rod 405 are respectively engaged with the integral screw 404 and the single-control coupling 502 for circumferential limiting transmission. In use, the pressure of a single pressure module during straightening can be independently adjusted. When it is necessary to adjust the straightening pressure of a certain pressure module individually, simply turn on the power supply of the electromagnet 503 of that pressure module, and the adjustment can be made through the single-control motor 304. After the electromagnet 503 is energized, it can magnetically attract the magnetic block 5011, which drives the retainer 501 to move upward and stretches the separation spring 5012. When the retainer 501 moves upward, it can drive the single-control coupling 502 to move synchronously. After the single-control coupling 502 moves upward, the clutch gear 5022 is inserted into the clutch tooth groove 5041. Therefore, when the single-control motor 304 rotates, the clutch gear 5022 can be engaged. When in motion, it can drive the control shaft 305 to rotate. When the control shaft 305 rotates, the control gear 3051 can drive the linkage gear 504 to rotate. When the linkage gear 504 rotates, the clutch groove 5041 can drive the single-control coupling 502 to rotate through the clutch gear 5022. When the single-control coupling 502 rotates, the transmission groove 5021 can drive the connecting rod 405 to rotate. The cross-sections of both ends of the connecting rod 405 are regular polygons. The interior of the integral screw 404 is provided with a synchronization groove 4041 that fits the bottom of the connecting rod 405. The interior of the single-control coupling 502 is provided with a transmission groove 5021 that fits the top of the connecting rod 405. The bottom of the connecting rod 405 is inserted into the interior of the synchronization groove 4041, and the top of the connecting rod 405... The connecting rod 405 is inserted into the transmission groove 5021. When the connecting rod 405 rotates, it can drive the integral screw 404 to rotate through the synchronous groove 4041. When the integral screw 404 rotates, it can drive the pressure plate 403 to independently rise and fall at the bottom of the positioning plate 402 through the rod thread, changing its usage position. The change of the usage position of the pressure plate 403 changes the compression degree of the pressure top spring 4031, that is, the straightening and shaping pressure of the straightening wheel 4011 at the bottom of the pressure module. The adjustment is convenient and quick. Since the electromagnets 503 of the other pressure modules are not energized, the usage state of the other pressure modules will not change. It can realize the diversified adjustment needs of straightening and shaping pressure, further improving the adaptability of the device.

[0034] Among them, the straightening wheel 4011 has an arc-shaped groove on its wheel surface that matches the outer circle of the cable. During use, the arc-shaped groove can fit against the surface of the cable during the cable straightening process, ensuring that the outer surface of the cable will not be dented or other phenomena during the straightening process, and ensuring stable use.

[0035] The specific usage and function of this embodiment: In this invention, the straightening module can realize the straightening and shaping operation of flexible cables. The cable is input into the interior of the straightening machine 1 through the input seat 201. After being straightened and shaped by the straightening module, it enters the constant temperature shaping module 6. The constant temperature heating of the constant temperature shaping module 6 softens and shapes the cable insulation layer, reducing the rebound after straightening. After that, the cable passes through the monitoring module 7, which monitors the straightening parameters of the cable. Finally, after being cooled and shaped by the cooling module 8, it is output into the interior of the straightening machine 1, completing a complete straightening operation. When the cable passes through the straightening module, it is subjected to the pressure straightening and shaping action of the pressure module. The control groove 3031 of the pressure bar 303 can control the positioning plate 402 through the linkage rod 4021. Positioning is achieved by using a fixed position for the positioning plate 402. The integral screw 404 integrates the positioning plate 402 and the pressure plate 403 into a single unit. The pressure plate 403 provides stable support for the pressure spring 4031 and transmits the spring force of the pressure spring 4031 to the pressure column 401 and its bottom straightening wheel 4011. When the cable passes through the straightening module, the straightening wheel 4011 applies this force to the cable, achieving straightening and shaping. Because the pressure bar 303 is inclined inside the input seat 201, the positioning plates 402 of the multiple pressure modules arranged along its long side are also sequentially inclined. The change in the position of the positioning plate 402 alters the pressure spring... The force exerted by the spring 4031 on the pressure column 401 and the straightening wheel 4011, i.e., the pressure during straightening and shaping, allows the positioning disks 402, arranged in a sequentially inclined manner, to gradually increase the straightening and shaping pressure of multiple pressure modules in the cable conveying direction. This achieves a gradual pressure straightening method for the cable, effectively preventing damage caused by excessive straightening pressure when the cable initially enters the input seat 201. The gradual pressure curve between the pressure modules can be freely adjusted. The function of adjusting the gradual pressure curve can be achieved by controlling the motor 202. When the motor 202 rotates, the drive gear 2021 drives the synchronous gear ring 203 to rotate. When the synchronous gear ring 203 rotates, it drives the synchronous gear 3011 to rotate. When the positioning rod 301 rotates, it drives the positioning seat 302 to move up and down inside the input seat 201 via the rod thread. As the positioning seat 302 moves, the control rod 3021 drives the pressure inclined rod 303 to rotate via the control groove 3031, thus changing the inclination of the pressure inclined rod 303. This change in inclination alters the position of the multiple pressure module positioning discs 402 arranged along its long side, thus changing the gradual pressure curve. This allows for the straightening and shaping of cables of different types and specifications, demonstrating strong adaptability. Furthermore, during this process, since the electromagnet 503 is not energized, the clutch gear 5022 disengages from the clutch tooth groove 5041 under the action of the release spring 5012.Therefore, the pressure mechanism 4 will not change the operating state of the control mechanism 5 during adjustment, nor will it jam the device. The pressure of a single pressure module during calibration can be independently adjusted, further improving the adaptability of the device. When it is necessary to adjust the calibration pressure of a certain pressure module individually, simply turn on the power supply of the electromagnet 503 of that pressure module, and adjust it through the single-control motor 304. After the electromagnet 503 is energized, it can magnetically attract the magnetic block 5011, causing the retainer 501 to move upward and lengthen the separation spring 5012. When the retainer 501 moves upward, it can drive the single-control coupling 502 to move synchronously. After the single-control coupling 502 moves upward, the clutch gear 5022 inserts into the clutch tooth groove 5041. Thus, when the single-control motor 304 rotates, it can drive the control shaft 305 to rotate. When the control shaft 305 rotates, the control gear 3051 can drive the linkage gear 5. When the linkage gear 504 rotates, the clutch tooth groove 5041 drives the single-control coupling 502 to rotate via the clutch gear 5022. When the single-control coupling 502 rotates, the transmission groove 5021 drives the connecting rod 405 to rotate. When the connecting rod 405 rotates, it drives the integral screw 404 to rotate via the synchronization groove 4041. When the integral screw 404 rotates, it drives the pressure plate 403 to independently rise and fall at the bottom of the positioning plate 402, changing its position. Changing the position of the pressure plate 403 changes the compression degree of the pressure top spring 4031, thus affecting the straightening and shaping pressure of the straightening wheel 4011 at the bottom of this pressure module. This adjustment is convenient and quick. Furthermore, since the electromagnets 503 of the other pressure modules are not energized, the operating state of the other pressure modules remains unchanged, enabling diversified adjustment of straightening and shaping pressure.

[0036] Example 2: Based on Example 1, the number of gradual positioning mechanisms 3 is not limited to three sets. The number can be increased or decreased according to cable specifications, straightening accuracy and shaping requirements. Different numbers of gradual positioning mechanisms 3 can adapt to cable straightening scenarios with different diameters and different degrees of flexibility. Increasing the number of circumferential straightening points can improve the roundness and straightness accuracy of the cable. Reducing the number of mechanisms can simplify the structure, reduce costs and improve the smoothness of conveying. This allows the device to flexibly switch between general and specialized applications for multi-specification cables, further expanding its applicability.

[0037] Example 3: Based on Examples 1 and 2, the wheel surface of the straightening wheel 4011 is not limited to setting an arc-shaped groove. It can be set with a corresponding groove shape according to the shape of the cable to adapt to the straightening and shaping needs of cables with different cross-sectional shapes such as round, flat, and multi-core irregular shapes. By matching the special groove shape with the shape of the cable, the pressure can be evenly distributed during the straightening process, avoiding local stress concentration that causes damage and deformation to the cable sheath. At the same time, it improves the positioning accuracy and shaping effect, and enhances the versatility and applicability of the device for cables of different shapes and specifications.
