Description

Technical Field

[0001] This invention relates to the field of shaping device technology, and in particular to a bending and shaping device for power cables. Background Technology

[0002] In power engineering construction, power equipment assembly, and low-voltage system wiring, bending and shaping of thin-walled insulated power cables is a critical process. Because of their thin sheath and low rigidity, these cables are prone to shape deviation, internal wrinkle buildup, and insufficient bending angle accuracy during bending, severely impacting the neatness of subsequent wiring and the stability of electrical connections.

[0003] In traditional processes, cable bending, heating and softening, and shaping and cooling are independent steps, requiring multiple cable transfers. This not only increases work time but also easily leads to springback of the bent shape during transfer. Furthermore, shaping often relies on natural cooling, which makes it difficult for thermoplastic sheath materials to solidify quickly and maintain the preset bending shape for a long time. Traditional devices lack effective limiting mechanisms, making it easy for cables to slip axially or deviate radially during bending, failing to meet the requirements of high-precision wiring. When bending thin-walled cables, the inner sheath is easily compressed and wrinkled, while the outer sheath is stretched and prone to loosening and deformation. In existing technologies, wrinkle removal is mostly done manually or by adding a separate wrinkle removal process, which is not only inefficient but also prone to sheath damage due to uneven manual operation. Some devices use simple pressure to remove wrinkles, which cannot solve the problem of material accumulation at the root, resulting in a high wrinkle residue rate. Therefore, this application proposes a power cable bending and shaping device. Summary of the Invention

[0004] The purpose of this invention is to address the problems of low automation in cable bending, low wrinkle removal efficiency, and easy springback after bending in the prior art, and to propose a power cable bending and shaping device.

[0005] The technical solution of the present invention: A power cable bending and shaping device includes a base plate and a worktable. The worktable is fixedly installed on the base plate. A sliding plate is symmetrically slidably installed on the worktable. A fixed platform is fixedly installed on one side of the sliding plate. A first forming roller is fixedly installed on the fixed platform. A sliding table is slidably installed on the sliding plate. A support plate is slidably installed on the worktable. A second forming roller is rotatably installed on the support plate. The second forming roller is half solid and half hollow. A negative pressure cavity is opened on the second forming roller. A plurality of through holes are opened on the negative pressure cavity. A limiting mechanism for limiting cables of different radii is provided on the worktable. A wrinkle-removing mechanism for removing wrinkles from the bent cable is provided on one side of the worktable.

[0006] Optionally, the limiting mechanism includes a first threaded rod rotatably mounted on the worktable, the first threaded rod being threadedly connected to the inner side of the support plate, a connecting plate slidably mounted on the bottom of the worktable, the connecting plate being fixedly connected to the slide plate, a second threaded rod rotatably mounted on the bottom of the worktable, the second threaded rod being threadedly connected to the connecting plate, a third threaded rod rotatably mounted on the slide plate, the third threaded rod being threadedly connected to the bottom of the slide table, a guide rod fixedly mounted on one side of the slide plate, and an mounting plate fixedly mounted on the guide rod.

[0007] Optionally, the wrinkle removal mechanism includes a support block slidably mounted on one side of the worktable. The support block is rotatably connected to one end of the second forming roller. A first gear is rotatably mounted on the support block and fixedly connected to the second forming roller. A negative pressure chamber is rotatably mounted on the first gear and communicates with the second forming roller. A second gear is rotatably mounted on the support block and meshes with the first gear. A main pipe is fixedly mounted on the guide cavity. A first pump body is fixedly mounted on one side of the base plate. A first side pipe is fixedly mounted on one side of the first pump body. A heating block is fixedly mounted on the first side pipe and one end of the first side pipe communicates with the main pipe. A second pump body is fixedly mounted on the other side of the base plate. A second side pipe is fixedly mounted on one end of the second pump body and fixedly mounted on the second side pipe. A micro compressor is fixedly mounted on the second side pipe and one end of the second side pipe communicates with the main pipe. A vacuum generator is fixedly mounted on one side of the base plate, and one end of the main pipe is fixedly connected to the vacuum generator.

[0008] Optionally, a first electronic valve is fixedly installed on the first side pipe, a second electronic valve is fixedly installed on the second side pipe, and a third electronic valve is fixedly installed on the main pipe.

[0009] Optionally, a first motor is fixedly mounted on the workbench, and the output shaft of the first motor is fixedly connected to the first threaded rod.

[0010] Optionally, a side plate is fixedly installed at the bottom of the workbench, and a second motor is fixedly installed on one side of the side plate. The output shaft of the second motor is fixedly connected to the second threaded rod.

[0011] Optionally, a third motor is fixedly mounted on the mounting plate, and the output shaft of the third motor is fixedly connected to the third threaded rod.

[0014] Optionally, a guide groove is provided on one side of the workbench, and the guide rod is slidably connected to the guide groove.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention utilizes a second motor to rotate a second threaded rod, thereby changing the distance between two sliding plates to accommodate cables of different radii. Simultaneously, a third motor rotates a third threaded rod, causing the sliding table to contact and limit the cable surface. Rotating the first threaded rod moves the first forming roller downwards, compressing and bending the cable. This achieves high-precision bending of cables of different sizes and improves the bending effect.

[0016] Furthermore, by activating the first pump and heating block, hot air is introduced into the negative pressure chamber to heat and stretch the sheath and cable at the bending point, reducing the material stiffness and shaping the bent cable, creating conditions for subsequent adsorption and wrinkle removal. After heating, the vacuum generator is switched to pump air, and the uniform adsorption force is generated by the through hole of the negative pressure chamber to stretch and flatten the sheath material that is pressed and accumulated on the inside.

[0017] Furthermore, by introducing cold air into the negative pressure chamber through the second pump and the micro compressor, the bending part is rapidly cooled, and the sheath material is quickly solidified from a softened and relaxed state to a shaped state, thereby improving the wrinkle removal effect.

[0018] This invention enables high-precision bending of cables of different sizes, improves bending effect, shapes and removes wrinkles from the bent cables, prevents cable springback, and improves processing efficiency. Attached Figure Description

[0027] Example 1, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention proposes a power cable bending and shaping device, including a base plate 1 and a worktable 2. The worktable 2 is fixedly installed on the base plate 1. A sliding plate 3 is symmetrically slidably installed on the worktable 2. A fixed platform 7 is fixedly installed on one side of the sliding plate 3. A first forming roller 6 is fixedly installed on the fixed platform 7. A sliding table 5 is slidably installed on the sliding plate 3. A support plate 20 is slidably installed on the worktable 2. A second forming roller 8 is rotatably installed on the support plate 20. The second forming roller 8 is half solid and half hollow. A negative pressure cavity 21 is opened on the second forming roller 8. A plurality of through holes are opened in the negative pressure cavity 21. The thin-walled cable to be bent is placed between the second forming roller 8 and the first forming roller 6. The sliding table 5 is moved to contact the surface of the thin-walled cable. At this time, the thin-walled cable is limited to avoid displacement of the cable during the bending process, which would affect the bending effect. A limiting mechanism for limiting cables of different radii is provided on the worktable 2. A wrinkle-removing mechanism for removing wrinkles from the bent cable is provided on one side of the worktable 2.

[0028] Example 2, as Figure 1 , Figure 4 and Figure 7As shown, the limiting mechanism includes a first threaded rod 19 rotatably mounted on the worktable 2, which is threadedly connected to the inner side of the support plate 20. A connecting plate 13 is slidably mounted on the bottom of the worktable 2, and the connecting plate 13 is fixedly connected to the slide plate 3. A second threaded rod 12 is rotatably mounted on the bottom of the worktable 2, and the second threaded rod 12 is threadedly connected to the connecting plate 13. A third threaded rod 18 is rotatably mounted on the slide plate 3, and the third threaded rod 18 is threadedly connected to the bottom of the slide table 5. A guide rod 17 is fixedly mounted on one side of the slide plate 3, and an mounting plate 15 is fixedly mounted on the guide rod 17. The thin-walled cable to be bent is placed on the first forming roller 6 and the second threaded rod 18. Between the two forming rollers 8, rotate the second threaded rod 12 to adjust the distance between the two forming rollers 8 to prevent the cable from being too thick to bend. After adjustment, rotate the third threaded rod 18, which drives the slide table 5 to move. One side of the slide table 5 contacts the surface of the cable to limit it and prevent the cable from shifting during bending, which would affect the bending effect. After limiting, rotate the solid part of the first forming roller 6 downward and rotate the first threaded rod 19. The first threaded rod 19 drives the first forming roller 6 to descend and bend the cable after limiting it. The bending angle increases with the displacement of the first forming roller 6.

[0029] Example 3, as Figure 1-8As shown, the wrinkle removal mechanism includes a support block 22 slidably mounted on one side of the worktable 2. The support block 22 is rotatably connected to one end of the second forming roller 8. A first gear 23 is rotatably mounted on the support block 22 and is fixedly connected to the second forming roller 8. A negative pressure chamber 21 is rotatably mounted on the first gear 23 and communicates with the second forming roller 8. A second gear 25 is rotatably mounted on the support block 22 and meshes with the first gear 23. A main pipe 27 is fixedly mounted on the guide cavity 24. A first pump body 28 is fixedly mounted on one side of the base plate 1. A first side pipe 31 is fixedly mounted on one side of the first pump body 28. A heating block 29 is fixedly mounted on the first side pipe 31. One end of the first side pipe 31 communicates with the main pipe 27. A heating block 29 is fixedly mounted on the other side of the base plate 1. A second pump body 34 is installed, with a second side pipe 37 fixedly mounted at one end. A micro compressor 35 is fixedly mounted on the second side pipe 37, and one end of the second side pipe 37 is connected to the main pipe 27. A vacuum generator 32 is fixedly mounted on one side of the base plate 1, and one end of the main pipe 27 is fixedly connected to the vacuum generator 32. A first electronic valve 30 is fixedly mounted on the first side pipe 31, a second electronic valve 36 is fixedly mounted on the second side pipe 37, and a third electronic valve 33 is fixedly mounted on the main pipe 27. After bending, the first threaded rod 19 is reversed, causing the first forming roller 6 to move upward until it slightly separates from the cable surface. The second gear 25 is then rotated, causing the first gear 23 to rotate, thus increasing the negative pressure chamber 2 of the first forming roller 6. With the cable facing downwards, the through-hole in the negative pressure chamber 21 can contact the cable. The first pump body 28 and heating block 29 are activated. The first pump body 28 delivers gas into the first side pipe 31, and the heating block 29 heats the gas in the first side pipe 31. The heated gas is then delivered into the negative pressure chamber 21 and finally ejected through the through-hole to heat the bent portion of the cable. This heats the bent cable to help it retain its shape and prevent springback after bending. Simultaneously, it heats the thin wall of the cable, making it easier to stretch and facilitating subsequent wrinkle removal. After heating, the first electronic valve 30 and the second electronic valve 36 are closed, and the third electronic valve 33 is opened. The vacuum generator 32 is activated, extracting air from the negative pressure chamber 21. At this time, the thin wall of the cable is heated by the pressure on the negative pressure chamber 21. The through-holes facilitate adsorption. Since the negative pressure chamber 21 is arc-shaped and fits snugly against the cable bend, when the cable bends and adheres to the surface of the negative pressure chamber 21, the vacuum generator 32 activates. The through-holes of the negative pressure chamber 21 generate a uniform negative pressure, which exerts an all-around adsorption force on the cable sheath. This forcefully stretches the pressure-accumulated sheath material on the inner side evenly outwards, forcing the material at the wrinkles to extend and flatten. The adsorption force ensures complete contact between the cable sheath and the arc-shaped surface of the negative pressure chamber, making the stress distribution of the sheath more uniform and eliminating the conditions for wrinkle formation at the root. After wrinkle removal, the second electronic valve 36 is opened, the third electronic valve 33 is closed, and the second pump 34 is activated. The second pump 34 delivers gas into the second side pipe 37, and the micro compressor 35 is activated to cool the gas.The bent sections are cooled to further improve the shaping of the cable and cable sheath.

[0030] like Figure 6 , Figure 7 and Figure 8 As shown, a first motor 10 is fixedly installed on the workbench 2. The output shaft of the first motor 10 is fixedly connected to the first threaded rod 19. The output shaft of the first motor 10 drives the first threaded rod 19 to rotate. A side plate 9 is fixedly installed at the bottom of the workbench 2. A second motor 11 is fixedly installed on one side of the side plate 9. The output shaft of the second motor 11 is fixedly connected to the second threaded rod 12. The output shaft of the second motor 11 drives the second threaded rod 12 to rotate. A third motor 16 is fixedly installed on the mounting plate 15. The output shaft of the third motor 16 is fixedly connected to the third threaded rod 18. The output shaft of the third motor 16 drives the third threaded rod 18 to rotate. A fourth motor 26 is fixedly installed on the support block 22. The output shaft of the fourth motor 26 is fixedly connected to the second gear 25. The output shaft of the fourth motor 26 drives the second gear 25 to rotate. A slide groove 4 is provided on the workbench 2. The slide plate 3 is slidably connected to the slide groove 4. A guide groove 14 is provided on one side of the workbench 2. The guide rod 17 is slidably connected to the guide groove 14.

[0031] Working principle: The thin-walled cable to be bent is placed between the first forming roller 6 and the second forming roller 8. The second threaded rod 12 is rotated to adjust the distance between the two second forming rollers 8 to prevent the cable from being too thick to complete the bending. After adjustment, the third threaded rod 18 is rotated, which drives the slide table 5 to move. One side of the slide table 5 contacts the surface of the cable to limit its movement and prevent the cable from shifting during bending, which would affect the bending effect. After limiting the movement, the solid part of the first forming roller 6 is rotated downwards. The first threaded rod 19 is rotated, which drives the first forming roller 6 to descend, bending the cable after it has been limited. The bending angle increases with the displacement of the first forming roller 6. After bending, the first threaded rod 19 is reversed, causing the first forming roller 6 to move upward until it slightly separates from the cable surface. The second gear 25 is then rotated, causing the first gear 23 to rotate, making the negative pressure chamber 21 of the first forming roller 6 face downward, allowing the through hole on the negative pressure chamber 21 to contact the cable. The first pump body 28 and the heating block 29 are then activated. The first pump body 28 delivers gas into the first side pipe 31, and the heating block 29 heats the gas in the first side pipe 31. The heated gas is then delivered back into the negative pressure chamber 21 and finally ejected from the through hole. The cable at the bend is heated to shape it and prevent springback. Simultaneously, the thin wall of the cable is heated to facilitate stretching and subsequent wrinkle removal. After heating, the first electronic valve 30 and the second electronic valve 36 are closed, and the third electronic valve 33 is opened, activating the vacuum generator 32. The vacuum generator 32 extracts air from the negative pressure chamber 21. At this time, the thin wall of the cable is attracted by the through holes on the negative pressure chamber 21. Because the negative pressure chamber 21 is arc-shaped and fits snugly against the cable bend, when the cable bends and adheres to the surface of the negative pressure chamber 21, the vacuum generator 32 activates, and the through holes in the negative pressure chamber 21 generate uniform pressure. The uniform negative pressure exerts an all-around adsorption and pulling force on the cable sheath, stretching the pressure-accumulated sheath material on the inside evenly to the surrounding areas. This forces the material at the folds to extend and flatten. The adsorption force makes the cable sheath completely fit the arc-shaped surface of the negative pressure chamber, making the stress distribution of the sheath more uniform and eliminating the conditions for wrinkle formation from the root. After wrinkle removal, the second electronic valve 36 is opened, the third electronic valve 33 is closed, and the second pump body 34 is started. The second pump body 34 delivers gas into the second side pipe 37, and the micro compressor 35 is started. The micro compressor 35 cools the gas and cools the bent part, further improving the shaping of the cable and cable sheath.

[0032] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
