Description

Technical Field

[0001] This utility model relates to the field of coil bending technology, and more specifically, to an automatic angle bending device for hollow coils. Background Technology

[0002] An air-core coil is an electronic component, typically composed of wire wound around a hollow cylinder or other hollow shape. Its main function is to generate inductance in circuits for applications such as filtering, tuning, and coupling. Compared to traditional iron-core coils, air-core coils have the following advantages: 1. Low loss: Due to the absence of an iron core, air-core coils have lower core losses, resulting in superior performance in high-frequency circuits. 2. High Q value: Q value is a parameter measuring inductance quality; air-core coils typically have a higher Q value, providing better filtering effects. 3. Wide bandwidth: Air-core coils have a wider frequency response range, making them suitable for broadband circuit applications. 4. No magnetic saturation: Iron-core coils are prone to magnetic saturation under high current, while air-core coils do not have this problem and can withstand larger currents. Air-core coils are widely used in electronic devices such as radio communication, television, audio equipment, and power supplies, and are an indispensable component in electronic circuits.

[0003] Chinese Patent Publication No. CN210817159U discloses a bending device for the outer wire connector of a hollow coil, including a device body. The device body includes a support leg, a mounting plate fixedly mounted on the top of the support leg, a fixing plate fixedly mounted on the back of the upper surface of the mounting plate, and a first fixing post fixedly mounted on the upper surface of the fixing plate. A first outer cylinder is fixedly sleeved on the outside of the first fixing post. This utility model drives a push rod to move forward through a drive mechanism, which in turn pushes the first clamping plate and the second clamping plate forward to bend the hollow coil. At the same time, the push rod moves upward, causing the limiting post to move into the housing. The limiting post pushes the locking block. When the locking block is engaged in the limiting groove, positioning is achieved. Positioning also has a shock absorption effect. The push rod stops moving, and the first clamping plate and the second clamping plate stop moving, completing the bending work and making the bending process more accurate.

[0004] However, the existing technical solutions mentioned above have the following drawbacks: when workers use the bending device to bend the hollow coils, the hollow coils may not be securely fixed due to their different sizes, causing them to shift and affecting the bending effect.

[0005] Therefore, it is necessary to provide an automatic bending device for hollow coils to solve the above problems. Utility Model Content

[0006] This invention provides an automatic bending device for hollow coils, which can improve the problem in related technologies that cannot bend hollow coils of different sizes.

[0007] This application provides an automatic bending device for hollow coils, including a frame, a support column, an adjustment mechanism, and a pressing component. The support column is disposed on the top surface of the frame, and the pressing component is disposed on the frame. The adjustment mechanism includes an adjustment component and a drive component. The adjustment component includes an adjustment plate, a first slider, an adjustment disk, a connecting column, and a fixing column. The fixing column is fixedly connected to the frame. The adjustment disk is disposed on the end of the fixing column away from the frame. A first sliding groove is formed on the adjustment disk, and the first slider is slidably connected on the first sliding groove. The adjustment plate is disposed on one end of the first slider, and the connecting column is disposed on the other end of the first slider. Multiple adjustment plates and first sliders are provided. The drive component is disposed on the adjustment disk and is used to drive the first slider to slide. The pressing component is used to press down the wire end of the hollow coil.

[0008] The technical solutions described above in this application embodiment have at least the following technical effects: When a worker needs to use an automatic hollow coil bending device to bend hollow coils of different sizes, the worker can use the drive component to make the first slider slide in the first slide groove. Then the first slider will drive the adjustment plate to expand outward, adjust the distance between the adjustment plate and the adjustment plate, and then increase the diameter distance. The worker can then put the hollow coil on the adjustment plate to complete the bending operation of hollow coils of different sizes.

[0009] This application provides an automatic bending device for hollow coils. Through the arrangement of an adjusting plate, adjusting disk, first slider, first slide groove, and driving components, it eliminates the need to change the bending device for different sizes of hollow coils. The device automatically adjusts the distance between the adjusting plate and the adjusting disk according to the size of the hollow coil, fixing it firmly on the adjusting plate. This prevents displacement of the hollow coil during bending operations, which would otherwise result in poor bending quality and potential metal fatigue fracture at the bend point during subsequent bending, rendering the hollow coil unusable and causing losses. This improves the convenience and efficiency of the device.

[0022] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application. The terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0024] The existing technical solutions mentioned above have the following drawbacks: When workers use the bending device to bend the hollow coils, the hollow coils may not be securely fixed due to different sizes, causing displacement of the hollow coils, affecting the bending effect, and leading to bending failure. When bending again, the bent part may break due to metal fatigue, rendering the hollow coil unusable, causing losses and reducing the working efficiency of the device.

[0025] In order to improve the problem in the related technology that it is impossible to bend hollow coils of different sizes.

[0026] Please see Figure 1 and Figure 4 An automatic bending device for hollow coils includes a frame 1, a support column 2, an adjustment mechanism 3, and a pressing component 6. The support column 2 is disposed on the top surface of the frame 1, the pressing component 6 is disposed on the frame 1, and the adjustment mechanism 3 includes an adjustment component 31 and a drive component 32.

[0027] Please see Figure 2 and Figure 4The adjustment assembly 31 includes an adjustment plate 311, a first slider 312, an adjustment disk 313, a connecting post 314, and a fixing post 315. The fixing post 315 is fixedly connected to the frame 1. The adjustment disk 313 is disposed on the end of the fixing post 315 away from the frame 1. The adjustment disk 313 has a first sliding groove 4. The first slider 312 is slidably connected in the first sliding groove 4. The adjustment plate 311 is disposed on one end of the first slider 312. The connecting post 314 is disposed on the other end of the first slider 312. Multiple adjustment plates 311 and first sliders 312 are provided. The drive assembly... The component 32 is disposed on the adjusting disk 313. The driving component 32 is used to drive the first slider 312 to slide. The pressing component 6 is used to press down the wire end of the hollow coil. The adjusting plate 311 is circular and surrounds the adjusting disk 313. The driving component 32 includes a first servo motor 321 and a rotating disk 322. The rotating disk 322 is disposed on the adjusting disk 313. The output shaft of the first servo motor 321 passes through the adjusting disk 313 and is connected to the rotating disk 322. A second sliding groove 5 is provided on the rotating disk 322, and the connecting post 314 is slidably connected on the second sliding groove 5.

[0028] With this setup, when using the automatic hollow coil bending device, the operator needs to bend hollow coils of the same size. First, the operator starts the first servo motor 321, which drives the rotating disk 322 to rotate. After the rotating disk 322 rotates, it passes through the connecting post 314 of the rotating disk 322 via the second sliding groove 5. Under the force of the rotating disk 322, it slides on the second sliding groove 5 as the rotating disk 322 rotates. The sliding of the connecting post 314 pushes the first slider 312 to slide outward. The adjusting plate 311 connected to the first slider 312 expands outward, increasing the distance between the adjusting plate 311 and the adjusting disk 313. The connecting post 314 slides to the second... When the chute 5 reaches the other end, the adjusting plate 311 reaches its maximum expansion diameter, and the distance between the adjusting plate 311 and the adjusting disk 313 reaches its maximum. After reaching the distance desired by the operator, the operator places the required hollow coil on the adjusting plate 311 and performs a bending operation on the hollow coil. In this way, the distance between the adjusting plate 311 and the adjusting disk 313 can be automatically adjusted according to different sizes of hollow coils, so that the hollow coil is fixed on the adjusting plate 311, so that the hollow coil will not be displaced during the bending operation, resulting in poor bending effect. When bending again, the bending point may break due to metal fatigue, causing the hollow coil to be scrapped and resulting in loss. This improves the convenience and working efficiency of the device.

[0029] Optionally, in some embodiments, please refer to Figure 2 and Figure 3 The frame 1 is equipped with a first cylinder 7. The pressing assembly 6 includes a pressure plate 61, a bidirectional lead screw 62, a slider 63, a pressing bar 64, and a second servo motor 65. The output shaft of the first cylinder 7 is connected to the pressure plate 61. The pressure plate 61 has a placement groove 11 and a third sliding groove 12, which communicate with each other. The second servo motor 65 is located on one side of the pressure plate 61. The bidirectional lead screw 62 is mounted on the placement groove 11. One end of the bidirectional lead screw 62 is rotatably connected to the pressure plate 61, and the other end of the bidirectional lead screw 62 is connected to the output shaft of the second servo motor 65. A slider 63 is movably sleeved on the outer surface of the bidirectional lead screw 62, and the slider 63 slides on the third slide groove 12. The slider 63 is provided with a lower pressure bar 64, and multiple lower pressure bars 64 are provided. A mounting block 9 is provided on the frame 1, and a second cylinder 8 is provided on the side of the mounting block 9. A bending block 10 is provided on the output shaft of the second cylinder 8.

[0030] With this setup, after the operator completes the adjustment of the adjustment plate 311, the hollow coil is placed on the adjustment plate 311. Then, the operator starts the second servo motor 65, causing the bidirectional lead screw 62 located in the placement slot 11 to rotate. The slider 63, threadedly connected to the bidirectional lead screw 62, slides on the bidirectional lead screw 62 as it rotates, thus adjusting the position of the slider 63 on the bidirectional lead screw 62. The pressure strip 64 on the slider 63 also slides on the sliding groove as the slider 63 slides. Because the lead screw used is a bidirectional lead screw 62, both sliders 63 slide simultaneously. The distance between the slider 63 and the wire end on the hollow coil... Similarly, when slider 63 is pressed down, it simultaneously presses down on both ends of the hollow coil. After adjusting slider 63 to the distance required by the operator, the operator starts the first cylinder 7. The first cylinder 7 drives the pressure plate 61 to press down and move towards the adjustment plate 311. The pressing bar 64 presses down on the two ends of the hollow coil, bending the ends to 90 degrees. Then, the second cylinder 8 pushes the bending block 10 to further bend the hollow coil. The operator then removes the hollow coil, completing its bending operation. This increases the bending efficiency of the hollow coil, eliminates the need for manual bending by the operator, allows control of the bending angle of the ends, improves the working efficiency of the device, and reduces the possibility of operator error.

[0031] Working Principle: When using the automatic hollow coil bending device, the operator needs to bend hollow coils of the same size. First, the operator starts the first servo motor 321, which drives the rotating disk 322 to rotate. After the rotating disk 322 rotates, it passes through the connecting post 314 of the rotating disk 322 via the second slide groove 5. Under the force of the rotating disk 322, it slides on the second slide groove 5 as the rotating disk 322 rotates. The sliding of the connecting post 314 pushes the first slider 312 to slide outward. The adjusting plate 311 connected to the first slider 312 expands outward, increasing the distance between the adjusting plate 311 and the adjusting disk 313. When the connecting post 314 slides to the other end of the second slide groove 5, the adjusting plate 311 reaches its maximum expansion diameter, and the distance between the adjusting plate 311 and the adjusting disk 313 reaches its maximum. After reaching the distance desired by the operator, the operator adjusts the adjusting plate 311 and puts the hollow coil on the adjusting plate 311. Then, the operator starts the second servo motor 65... The bidirectional lead screw 62 in the placement slot 11 rotates under the rotation of the second servo motor 65. The slider 63, threadedly connected to the bidirectional lead screw 62, slides on the bidirectional lead screw 62 as it rotates, thus adjusting the position of the slider 63 on the bidirectional lead screw 62. The pressure strip 64 on the slider 63 also slides on the sliding groove as the slider 63 slides. Because the lead screw used is a bidirectional lead screw 62, both sliders 63 slide simultaneously. The slider 63 interacts with the wire end on the hollow coil. With the distance being the same, when slider 63 is pressed down, it will simultaneously press down on both ends of the hollow coil. After adjusting slider 63 to the distance required by the operator, the operator starts the first cylinder 7. The first cylinder 7 drives the pressure plate 61 to press down and move towards the adjustment plate 311. The pressing bar 64 presses down on the two ends of the hollow coil, bending the ends to 90 degrees. Then, the second cylinder 8 pushes the bending block 10 to further bend the hollow coil. Then the operator removes the hollow coil, completing its bending operation.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
