Description

Technical Field

[0001] This invention relates to the field of power equipment manufacturing technology, specifically to a quick-release insulated tube conductor bending machine. Background Technology

[0002] The insulated conductor is a critical conductive component in power transmission systems, widely used in high-voltage transmission scenarios such as substations and converter stations. It typically consists of a metal conductor encased in an insulating layer and needs to be processed into a specific curvature using a bending machine to meet installation layout requirements. Existing bending machines mainly consist of core components such as a bending seat, bending rollers, bending sleeves, and a drive mechanism. However, these traditional bending machines encounter the following problems in practical applications: Difficulty in removing the conductor: After bending, the conductor is tightly clamped between the bending wheel, bending rail and bending sleeve, and the deformation caused by the bending part will increase the friction between it and the components. Workers usually have to forcibly pull the conductor from the bent end, which not only requires a lot of external force, but also easily scratches the surface of the conductor. Insufficient bending precision control: Traditional models lack angle indicator devices and rely on operators' experience to judge the bending angle, which can easily lead to angle deviations during batch processing. Inconvenient conductor positioning and adjustment: The initial position of the conductor (such as the length of a straight segment or the starting point of a bend) needs to be measured and adjusted manually, which is inefficient and has poor repeatability. Poor equipment adaptability: The frame height and position are fixed, making it difficult to match different workshop floor conditions or conductor placement heights; multiple people are required to move it, resulting in insufficient flexibility. Summary of the Invention

[0003] The first technical problem to be solved by the present invention is to provide a quick-release insulated tube conductor bending machine. By optimizing the bending wheel disassembly structure, the problem of difficult conductor removal in existing bending machines is solved, thereby achieving efficient conductor bending processing.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A quick-release insulated tube conductor bending machine includes a vertically arranged frame, a bending seat mounted on the top of the frame, a bending rail fixed inside the bending seat and a rotating bending wheel, a bending sleeve for conductor insertion mounted on the bending wheel, and a drive mechanism for rotating the bending wheel mounted below the frame. The core improvement lies in the following: a quick-release assembly with a rotating shaft coaxially arranged with the bending wheel is mounted on the outside of the bending seat, and the bending wheel rotates around the quick-release assembly. The quick-release assembly is completely pulled out of the bending wheel by a pull-out method, at which point the bending wheel and the conductor inserted into the bending sleeve can be removed together.

[0005] By adopting the above solution, the bending wheel can be quickly separated through the quick-release assembly of the rotating shaft, solving the problem of conductor removal, avoiding friction between the conductor and the bending rail, greatly reducing removal resistance, and reducing the risk of the conductor surface being scratched; and during maintenance, the bending wheel can be directly removed for cleaning without disassembling the whole machine, greatly shortening the operation time.

[0006] In a preferred embodiment of a quick-release insulated tube conductor bending machine, the drive mechanism includes a swing arm that rotates on the left side of the bending seat via a rotating sleeve and is coaxially arranged with the bending seat. The end of the swing arm away from the rotating sleeve is movably connected to a hydraulic cylinder that is inclinedly installed below the frame. The lever-type drive structure of the swing arm and the hydraulic cylinder converts the horizontal thrust of the hydraulic cylinder into the rotational torque of the bending wheel, which is more labor-saving than direct drive and can stably output a large torque.

[0007] In a preferred embodiment of a quick-release insulated tube conductor bending machine, the quick-release shaft assembly includes a main pin that passes through the rotating sleeve and is inserted into a central hole on the bending wheel. A side pin, parallel to the main pin, is connected to the main pin via a connecting plate. The locking mechanism between the main pin and the side pin ensures the stability of the bending wheel during rotation. A pull ring is connected to the outside of the connecting plate for easy pulling of the main pin and the side pin. The pull ring design allows the operator to pull the pins with one hand, achieving bending wheel disassembly within seconds, far exceeding the efficiency of traditional bolt disassembly. The side pin can pass through the swing arm and be inserted into a side insertion hole on the bending wheel. When the side pin is inserted into the side insertion hole, the bending wheel rotates synchronously with the swing arm. The cooperation between the side pin and the swing arm achieves linkage locking between the drive mechanism and the bending wheel, ensuring effective transmission of driving force.

[0008] As a preferred embodiment of a quick-release insulated tube conductor bending machine, the quick-release shaft assembly also includes a positioning pin connected to the outside of the bending seat. A sliding plate slidably mounted on the positioning pin and movably connected to the main pin is mounted on the positioning pin. A push spring is fitted on the positioning pin to push the sliding plate to insert the main pin into the center hole. The push spring automatically pushes the main pin into the center hole through the sliding plate, ensuring that the bending wheel is always inserted into the center hole without the need for continuous manual force, thus avoiding accidental loosening during processing. When disassembly is required, only the spring force of the push spring needs to be overcome to pull the pull ring, making the operation simple and highly reliable.

[0009] In a preferred embodiment of a quick-release insulated tube conductor bending machine, a horizontally arranged slide rail is connected to the right side of the bending seat. A slide block is slidably mounted on the slide rail, and the initial position of the conductor can be precisely adjusted by sliding the slide block to meet the requirements of high-precision processing. A chuck is clamped and mounted inside the slide block, and a positioning plate for conductor positioning is coaxially connected to the chuck. The chuck is tightened by a set screw that passes through the bending seat. The cooperation between the positioning plate and the chuck ensures that the conductor axis is aligned with the center of the bending rail, avoiding deviation during bending.

[0010] In a preferred embodiment of a quick-release insulated tube conductor bending machine, two slide rails are provided, which are parallel to each other and spaced apart. The two slide rails are square slide rails, and two square grooves are opened at the bottom of the slide block. The cooperation between the square slide rails and the guide wheels restricts the rotational freedom of the slide block, allowing it to slide only in a straight line, thus ensuring the straightness of conductor positioning. Guide wheels also rotate and slide in contact with the surface of the square slide rails within the square grooves. The guide wheels reduce the sliding friction resistance, making the operation easier.

[0011] The second technical problem to be solved by the present invention is to provide a quick-release insulating tube conductor bending machine. By adding an angle and length display device, the problem of insufficient bending accuracy control and inconvenient conductor positioning and adjustment in existing bending machines is solved, thereby achieving precise conductor bending processing.

[0012] To achieve the above objectives, the present invention provides the following technical solution: Based on the above scheme, a bending disc that displays the rotation angle of the bending seat is fixed on the outside of the bending seat, and a pointer pointing to the bending angle value in the bending disc is coaxially installed on the bending seat. A ruler that displays the total length of the conductor is also fixed on the surface of the slide rail.

[0013] By adopting the above solution, the combination of bending disc and pointer can display the current bending angle in real time. Operators can accurately control the degree of bending according to process requirements, avoiding errors in manual estimation. The ruler can directly read the length of the straight section of the conductor without the need for additional measuring tools, thus improving operational efficiency.

[0014] The third technical problem to be solved by the present invention is to provide a quick-release insulating tube conductor bending machine, which solves the problem of poor equipment adaptability in existing bending machines by improving the adjustability of the frame, and realizes safe conductor bending processing.

[0015] To achieve the above objectives, the present invention provides the following technical solution: Based on the above scheme, a horizontally arranged horizontal support is connected to the bottom of the frame, and a telescopic support is housed inside the horizontal support. A set screw for positioning the telescopic support is installed on the horizontal support. Casters are connected to the ends of both the horizontal support and the telescopic support. A lifting support is connected to the bottom of the slide rail, and the lifting support is housed inside a vertically arranged vertical support. A set screw for positioning the lifting support is installed on the vertical support.

[0016] By adopting the above solution, the stability of the machine frame can be adjusted by the telescopic support column, improving processing safety, and quick movement can be achieved by the casters, eliminating the need for multiple people to carry it. The telescopic support column is stored inside the horizontal support column, and the size of the equipment is reduced after folding, saving storage space. The height of the slide rail can be adjusted by the lifting support column to match different workshop floor heights or conductor placement positions, making it highly versatile.

[0017] The beneficial effects of this invention are: 1. Enhanced core functions: The quick-release assembly of the pivot shaft enables rapid separation of the bending wheel, solving the problem of conductor removal, avoiding friction between the conductor and the bending rail, significantly reducing removal resistance, and reducing the risk of scratching the conductor surface; in addition, the bending wheel can be directly removed for cleaning during maintenance without disassembling the entire machine, greatly shortening the operation time. 2. Ensures processing accuracy: The combination of bending disc and pointer can display the current bending angle in real time, allowing operators to accurately control the degree of bending according to process requirements and avoid errors from manual estimation; while the ruler can directly read the length of the conductor straight segment without the need for additional measuring tools, improving operational efficiency; 3. Ease of operation: When in use, the quick-release assembly of the swivel shaft automatically pushes the main pin into the center hole through the slide plate, ensuring that the bending wheel is always inserted into the center hole without the need for continuous manual force, thus avoiding accidental loosening during processing; when disassembly is required, simply overcome the spring force of the push spring to pull the pull ring, making the operation simple and highly reliable. 4. Enhanced adaptability: The stability of the machine frame can be adjusted by the telescopic support column, improving processing safety, and the casters enable quick movement without the need for multiple people to carry it. The telescopic support column is stored inside the horizontal support column, and the size of the equipment is reduced when folded, saving storage space. The height of the slide rail can be adjusted by the lifting support column to match different workshop floor heights or conductor placement positions, making it highly versatile.

Detailed Implementation

[0021] 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 embodiments of the present invention, and not all embodiments. Based on the 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.

[0022] like Figures 1 to 6As shown, a quick-release insulated tube conductor bending machine is provided for processing the insulated tube conductor 24 into a specific arc. It includes a vertically arranged frame 1, a bending seat 2 installed above the frame 1, a bending rail 3 fixed inside the bending seat 2, and a rotating bending wheel 4. A bending sleeve 5 for the conductor 24 to extend into is installed on the bending wheel 4, and a drive mechanism 6 for driving the bending wheel 4 to rotate is installed below the frame 1. The core improvement is that a quick-release assembly 7 with a rotating shaft is installed on the outside of the bending seat 2 and is coaxially arranged with the bending wheel 4. The bending wheel 4 rotates around the quick-release assembly 7, and the quick-release assembly 7 is completely pulled out from the bending wheel 4 by a pull-out method. At this time, the bending wheel 4 and the conductor 24 extending into the bending sleeve 5 can be taken out together. The quick-release assembly 7 of the rotating shaft enables the rapid separation of the bending wheel 4, solving the problem of removing the conductor 24, avoiding friction between the conductor 24 and the bending rail 3, greatly reducing the removal resistance, and also reducing the risk of the conductor 24 surface being scratched; in addition, the bending wheel 4 can be directly removed for cleaning during maintenance without disassembling the whole machine, greatly shortening the operation time.

[0023] like Figures 2 to 4 As shown, the drive mechanism 6 includes a swing arm 62 that rotates on the left side of the bending seat 2 via a rotating sleeve 8 and is coaxially arranged with the bending seat 2. The end of the swing arm 62 away from the rotating sleeve 8 is movably connected to a hydraulic cylinder 61 that is inclinedly installed below the frame 1. The lever-type drive structure of the swing arm 62 and the hydraulic cylinder 61 converts the horizontal thrust of the hydraulic cylinder 61 into the rotational torque of the bending wheel 4. Compared with direct drive, it is more labor-saving and can stably output a large torque.

[0024] like Figures 3 to 4 , Figure 7 As shown, the quick-release assembly 7 includes a main pin 71 that passes through the rotating sleeve 8 and is inserted into the central hole 25 on the bending wheel 4. A side pin 72, parallel to the main pin 71, is connected to the main pin 71 via a connecting plate 74. The locking mechanism of the main pin 71 and the side pin 72 ensures the stability of the bending wheel 4 during rotation. A pull ring 73 is connected to the outside of the connecting plate 74 to facilitate pulling out the main pin 71 and the side pin 72. The pull ring 73 is designed so that the operator can pull out the pins with one hand, and the bending wheel 4 can be disassembled in a few seconds, which is far more efficient than traditional bolt disassembly. The side pin 72 can pass through the swing arm 62 and be inserted into the side insertion hole 26 on the bending wheel 4. When the side pin 72 is inserted into the side insertion hole 26, the bending wheel 4 can rotate synchronously with the swing arm 62. The cooperation between the side pin 72 and the swing arm 62 realizes the linkage locking between the drive mechanism 6 and the bending wheel 4, ensuring the effective transmission of driving force.

[0025] Continue as Figures 3 to 4 , Figure 7As shown, the quick-release assembly 7 of the rotating shaft also includes a positioning pin 75 connected to the outside of the bending seat 2. A sliding plate 76 slidably mounted on the positioning pin 75 and movably connected to the main pin 71 is mounted on the positioning pin 75. A push spring 77 is fitted on the positioning pin 75 to push the sliding plate 76 to cause the main pin 71 to insert into the center hole 25. The push spring 77 automatically pushes the main pin 71 into the center hole 25 through the sliding plate 76, ensuring that the bending wheel 4 is always inserted into the center hole 25 without the need for continuous manual force, thus avoiding accidental loosening during processing. When disassembly is required, it is only necessary to overcome the elastic force of the push spring 77 to pull the pull ring 73, which is simple to operate and highly reliable.

[0026] like Figures 8 to 10 As shown, a horizontally arranged slide rail is connected to the right side of the bending seat 2. A slide block 12 is slidably installed on the slide rail. The initial position of the conductor 24 can be precisely adjusted by sliding the slide block 12 to meet the requirements of high-precision processing. A chuck 13 is clamped and installed inside the slide block 12. A positioning plate 14 for positioning the conductor 24 is coaxially connected to the chuck 13. The chuck 13 is fastened by a set screw 15 that passes through the bending seat 2. The cooperation between the positioning plate 14 and the chuck 13 can ensure that the axis of the conductor 24 is aligned with the center of the bending rail 3 to avoid deviation during bending.

[0027] like Figure 5 As shown, a bending disk 9 that displays the rotation angle of the bending disk 2 is fixed on the outside of the bending seat 2, and a pointer 10 that points to the bending angle value in the bending disk 9 is coaxially installed on the bending seat 2. The combination of the bending disk 9 and the pointer 10 can display the current bending angle in real time. The operator can accurately control the degree of bending according to the process requirements and avoid errors in manual estimation.

[0028] like Figures 8 to 9 As shown, there are two slide rails, which are parallel to each other and spaced apart. The two slide rails are square slide rails 11. The bottom of the slide block 12 has two square grooves 17. The cooperation between the square slide rail 11 and the guide wheel 18 restricts the rotational freedom of the slide block 12, allowing it to slide only in a straight line, thus ensuring the straightness of the conductor 24 positioning. The guide wheel 18 also rotates and slides in contact with the surface of the square slide rail 11 within the square groove 17. The guide wheel 18 reduces the sliding friction resistance, making it easier to operate.

[0029] like Figure 10 As shown, a ruler 16 is also fixed on the surface of the slide rail to display the total length of the conductor 24. The ruler 16 can directly read the length of the straight segment of the conductor 24 without the need for additional measuring tools, thus improving operational efficiency.

[0030] like Figure 8As shown, a lifting support column 19 is connected below the slide rail. The lifting support column 19 is housed in a vertically arranged vertical support column 20. A set screw 15 is installed on the vertical support column 20 to position the lifting support column 19. The height of the slide rail can be adjusted by the lifting support column 19 to match different workshop floor heights or conductor 24 placement positions, making it highly versatile.

[0031] like Figure 1 As shown, a horizontally arranged horizontal support column 21 is connected below the frame 1. A telescopic support column 22 is housed inside the horizontal support column 21, and a set screw 15 is installed on the horizontal support column 21 to position the telescopic support column 22. Casters 23 are connected to the ends of both the horizontal support column 21 and the telescopic support column 22. The stability of the frame 1 can be adjusted by the telescopic support column 22, improving processing safety, and the casters 23 enable quick movement without the need for multiple people to carry it. The telescopic support column 22 is housed inside the horizontal support column 21, and the size of the equipment is reduced when folded, saving storage space.

[0032] Working principle of this quick-release insulating tube conductor bending machine: Initial positioning: Insert one end of conductor 24 into bending sleeve 5, and clamp the other end through positioning plate 14 on slide 12. Adjust the position of slide 12 (measure the length with ruler 16) and the height of slide rail (through lifting support 19) to ensure that the axis of conductor 24 is aligned with the center of bending rail 3. Bending process: Start hydraulic cylinder 61 to push swing arm 62 to rotate around rotating sleeve 8, drive bending wheel 4 to rotate, conductor 24 bends along bending rail 3, and its complete angle is monitored in real time by bending disc 9 and pointer 10; Quick demolding: After processing, pull the pull ring 73 to remove the main pin 71 and side pin 72, release the installation of the bending wheel 4, and remove the bending wheel 4 and conductor 24 as a whole from the bending seat 2. Figure 6 As shown, the friction between conductor 24 and bending rail 3 can be detected at this time, which greatly reduces the removal resistance and at the same time reduces the risk of the surface of conductor 24 being scratched.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
