Description

Technical Field

[0001] This utility model relates to the field of inductor coil processing technology, and more specifically, to an inductor coil lead bending machine. Background Technology

[0002] An inductor is made by winding a wire one turn after another around an insulating tube. The wires are insulated from each other, and the insulating tube can be hollow or contain an iron core or a magnetic powder core. It is an electronic component that works by utilizing the principle of electromagnetic induction.

[0003] Chinese patent application number CN201921696400.5 discloses an inductor coil lead bending machine, belonging to the field of inductor coil technology. It includes a device body, a base installed at the lower end of the device body, a housing installed through the side of the top of the base, a hydraulic cylinder installed at the upper end of the device body, a groove embedded at the lower end of the hydraulic cylinder, a rotating disk rotating at the upper end of the base, a bracket installed at the upper end of the rotating disk, and docking rings installed on both sides at the lower end of the bracket.

[0004] In the above technical solution, a support is provided, and the inductor coil is placed on the base and the upper end of the support. This allows the rotating disk to be rotated manually, with the rotation angle precisely measured by referring to the angle marked on the outer side of the scale. The rotating disk drives the support to rotate. After rotating to the required angle, the sliding rod slides inside the track, allowing the rotating disk to be locked and limited by the sliding rod. Traditional inductor coil lead bending machines typically use a bending column to bend the circular inductor coil leads. First, after the circular inductor coil is wound, the two lead wires are scattered, requiring manual arrangement of the lead wires before bending. This not only increases the number of operation steps but also reduces production efficiency. Second, when the lead wires are placed on the bending machine's workbench for bending, the dispersion of the lead wires can easily lead to inaccurate or inconsistent bending, affecting the bending quality of the lead wires. After bending, the entire inductor coil will be wrapped on the guide block, making it difficult to remove. This further increases the difficulty of handling and time costs. Utility Model Content

[0005] The purpose of this invention is to provide an inductor coil lead bending machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An inductor coil lead bending machine includes a bending machine body. A fixed frame is fixedly mounted on the surface of the bending machine body. A fixed plate is fixedly mounted on the middle of the end surface of the fixed frame. A through-type guide post is fixedly connected to the surface of the fixed plate. Multiple sliding rods are slidably connected to the surface of the fixed plate. An arc-shaped support plate is fixedly connected to the top surface of any one of the sliding rods. An inductor coil body is placed on the surface of the arc-shaped support plate. Two lead wires are provided on the surface of the inductor coil body. A support frame is fixedly mounted on the side surface of the fixed frame. A fixed seat is fixedly connected to the surface of the support frame. Two arc-shaped groove plates for bending the lead wires are fixedly connected to the surface of the fixed seat. A straightening plate for straightening the lead wires is fixedly mounted on the surface of each arc-shaped groove plate. The straightening plate is connected to and matches the arc-shaped groove plate. A pressure cylinder that can move vertically up and down is provided above the guide post.

[0008] Preferably, there are four slide rods, and the four slide rods are arranged in a circular array around the guide post, and a first spring is sleeved on the surface of each slide rod.

[0009] Preferably, a mounting bracket is fixedly installed on the side surface of the bending machine body, and an electric telescopic rod is fixedly installed on the bottom surface of the mounting bracket. The telescopic end of the electric telescopic rod is fixedly connected to the end surface of the pressure cylinder.

[0010] Preferably, one end of the first spring is fixedly connected to the bottom surface of the arc-shaped support plate, and the other end of the first spring is fixedly connected to the surface of the fixed plate. The arc-shaped support plate is elastically connected to the fixed plate through the first spring.

[0011] Preferably, the surface of the guide post has the same number of grooves as the sliding rods, and a matching slider is slidably connected inside each groove. The inner side of the slider has an inclined groove, and the inner top surface of the guide post has a fixed plate with the same number of grooves. A guide rod is slidably connected to the surface of each fixed plate, and one end of the guide rod is fixedly connected to the inner side of the top of the slider. A second spring for the slider's reset movement is sleeved on the surface of each guide rod.

[0012] Preferably, the guide post is slidably connected to an insert post, and the surface of the insert post is fixedly fitted with an inclined block that matches the inclined groove.

[0013] Preferably, one end of the second spring is fixedly connected to the inner side of the slider, and the other end of the second spring is fixedly connected to the surface of the fixing plate.

[0014] Preferably, the bottom surface of the guide post is threaded with a threaded rod, the bottom surface of the insertion post is rotatably connected with a rotating ring, one end of the threaded rod is rotatably connected to the insertion post through the rotating ring, and the other end of the threaded rod is fixedly connected with a knob.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1) When using this inductor coil lead bending machine, the pressure cylinder moves downwards on the surface of the inductor coil body. At this time, the inductor coil body moves downwards, squeezing the arc-shaped support plate downwards and compressing the first spring. During the downward movement of the two lead wires, they are brought together by the action of two straightening plates. When the lead wires move along the straightening plates into the arc-shaped groove plate, as the electric telescopic rod continues to extend, the lead wires are bent during the relative movement of the arc-shaped groove plate and the pressure cylinder. Compared with traditional bending devices, this bending machine body is equipped with two straightening plates to bring together the scattered lead wires, eliminating the need for manual pre-arrangement of the lead wires. This not only improves the bending efficiency of the inductor coil leads but also improves the bending quality of the lead wires. After bending is completed, the arc-shaped support plate and the slide rod are reset under the action of the first spring. During the reset process of the arc-shaped support plate, the inductor coil body is lifted up, reducing the difficulty of handling and time cost.

[0017] 2) When this inductor coil lead bending machine is in use, the insert moves upward inside the guide post, which in turn causes the inclined block to move and squeeze the inclined groove. At this time, the slider moves outward from the guide post. When the surface of the slider contacts the inner diameter of the inductor coil body, the surface of the slider is used to guide the inductor coil body during its downward movement, preventing the lead wire from shaking during the bending process, further improving the bending quality. It is also suitable for inductor coil bodies with different inner diameter specifications, increasing the functionality of the bending machine body. Attached Figure Description

Detailed Implementation

[0025] Example 1: Please refer to Figure 1 - Figure 6 An inductor coil lead bending machine includes a bending machine body 1, which is a mechanical device for bending lead wires 9. A fixing frame 2 is fixedly mounted on the surface of the bending machine body 1. A fixing plate 3 is fixedly mounted on the middle of the end surface of the fixing frame 2. A through-type guide post 4 is fixedly connected to the surface of the fixing plate 3. The guide post 4 is used to guide the movement of the inductor coil body 8. A plurality of sliding rods 5 are slidably connected to the surface of the fixing plate 3. An arc-shaped support plate 6 is fixedly connected to the top surface of any one of the sliding rods 5. The inductor coil body 8 is placed on the surface of the arc-shaped support plate 6. In its natural state, the support plate 6 supports the inductor coil body 8. In its reset state, the arc-shaped support plate 6 lifts the inductor coil body 8. The inductor coil body 8 is a conventional circular electromagnetic induction coil. Two lead wires 9 are provided on the surface of the inductor coil body 8. A support frame 10 is fixedly installed on the side surface of the fixing frame 2. A fixing seat 11 is fixedly connected to the surface of the support frame 10. Two arc-shaped groove plates 13 for bending the lead wires 9 are fixedly connected to the surface of the fixing seat 11. The surfaces of the arc-shaped groove plates 13 are all fixedly installed with tools for straightening the lead wires. The straightening plate 12 of the lead wire 9 is used for guiding and gathering the lead wire 9. The straightening plate 12 is connected and matched with the arc-shaped groove plate 13. A pressure cylinder 14 that can move vertically up and down is set above the guide post 4. The pressure cylinder 14 acts on the surface of the inductor coil body 8 and moves downward. At this time, the inductor coil body 8 moves downward and squeezes the arc-shaped support plate 6 to move downward and compress the first spring 7. During the downward movement of the two lead wires 9, they are gathered under the action of the two straightening plates 12. When the lead wire 9 moves along the straightening plate 12 into the arc-shaped groove plate 13, it is moved downward with the electric current. As the telescopic rod 16 continues to extend, the lead wire 9 is bent during the relative movement of the arc-shaped groove plate 13 and the pressure cylinder 14. Compared with traditional bending devices, the bending machine body 1 is equipped with two straightening plates 12 to bring together the dispersed lead wires 9, eliminating the need for manual pre-arrangement of the lead wires 9. This not only improves the bending efficiency of the inductor coil leads but also enhances the bending quality of the lead wires 9. After bending, the arc-shaped support plate 6 and the slide bar 5 are reset under the action of the first spring 7. During the reset process, the arc-shaped support plate 6 lifts up the inductor coil body 8, reducing the difficulty of handling and time costs.

[0026] There are four sliders 5, and the four sliders 5 are arranged in a circular array around the guide post 4. A first spring 7 is sleeved on the surface of any slider 5. The circular array of the four sliders 5 around the guide post 4 ensures the stability of the inductor coil body 8 during movement.

[0027] A mounting bracket 15 is fixedly installed on the side surface of the bending machine body 1, and an electric telescopic rod 16 is fixedly installed on the bottom surface of the mounting bracket 15. The electric telescopic rod 16 is a conventional electric control push rod in the prior art. The telescopic end of the electric telescopic rod 16 is fixedly connected to the end surface of the pressure cylinder 14, and the electric telescopic rod 16 provides a power source for the movement of the pressure cylinder 14.

[0028] One end of the first spring 7 is fixedly connected to the bottom surface of the arc-shaped support plate 6, and the other end of the first spring 7 is fixedly connected to the surface of the fixed plate 3. The arc-shaped support plate 6 is elastically connected to the fixed plate 3 through the first spring 7. After bending, the arc-shaped support plate 6 and the slide bar 5 are reset under the action of the first spring 7. During the reset process of the arc-shaped support plate 6, the inductor coil body 8 is lifted up, which reduces the difficulty of picking up and the time cost.

[0029] The steps of using this utility model are as follows: When using this inductor coil lead bending machine, firstly, the inductor coil body 8 is placed on the outer surface of the guide post 4 and slid downwards onto the surface of the arc-shaped support plate 6. At this time, the two lead wires 9 face the straightening plate 12. The electric telescopic rod 16 extends and moves with the pressure cylinder 14, causing the pressure cylinder 14 to act on the surface of the inductor coil body 8 and move downwards. At this time, the inductor coil body 8 and the two lead wires 9 move downwards and squeeze the arc-shaped support plate 6, causing the arc-shaped support plate 6 to move downwards with the sliding rod 5 and compress the first spring 7. During the downward movement of the two lead wires 9, under the action of the two straightening plates 12, the two lead wires 9 move in a converging direction along the surface of the straightening plate 12. When the lead wires 9 move along the straightening plate 12 into the arc-shaped groove plate 13, as the electric telescopic rod 16 continues to extend, the lead wires 9 are bent during the relative movement of the arc-shaped groove plate 13 and the pressure cylinder 14. After bending is completed, the electric telescopic rod 16 retracts, and at this time, the arc-shaped support plate 6 and the sliding rod 5 are reset under the action of the first spring 7. During the resetting process of the arc-shaped support plate 6, the inductor coil body 8 is lifted up for easy handling. This solution uses the pressure cylinder 14 to act on the surface of the inductor coil body 8 and move downwards. At this time, the inductor coil body 8 moves downwards, pressing the arc-shaped support plate 6 downwards and compressing the first spring 7. During the downward movement of the two lead wires 9, they are brought together by the two straightening plates 12. When the lead wires 9 move along the straightening plates 12 into the arc-shaped groove plate 13, as the electric telescopic rod 16 continues to extend, the lead wires 9 are bent during the relative movement of the arc-shaped groove plate 13 and the pressure cylinder 14. Compared with the traditional bending device, the bending machine body 1 is equipped with two straightening plates 12 to bring together the scattered lead wires 9, eliminating the need for manual pre-arrangement of the lead wires 9. This not only improves the bending efficiency of the inductor coil leads but also improves the bending quality of the lead wires 9. After bending, the arc-shaped support plate 6 and the slide rod 5 are reset by the action of the first spring 7. During the resetting process of the arc-shaped support plate 6, the inductor coil body 8 is lifted up, reducing the difficulty of handling and time cost.

[0030] Example 2: Please refer to Figure 1 - Figure 6The difference from embodiment 1 is that the surface of the guide post 4 has the same number of grooves 17 as the slide rod 5. Each groove 17 has a matching slider 18 slidably connected inside it. The sliders 18 and slide rods 5 are staggered, and their movements do not interfere with each other. The inner surface of the slider 18 has an inclined groove 19. The top surface of the guide post 4 has a fixed plate 20 with the same number of grooves 17. Each fixed plate 20 has a guide rod 21 slidably connected to its surface. The guide rod 21 guides the movement of the slider 18, and one end of the guide rod 21 is connected to the inner surface of the top of the slider 18. The fixed connection is achieved by attaching a second spring 22 to the surface of any guide rod 21 for the reset movement of the slider 18. The spring 22 moves upward within the guide post 4 via the insert post 23, thereby causing the inclined block 24 to move and press the inclined groove 19. At this time, the slider 18 moves outward from the guide post 4. When the surface of the slider 18 contacts the inner diameter of the inductor coil body 8, the surface of the slider 18 is used to guide the inductor coil body 8 during its downward movement, preventing the lead wire 9 from shaking during the bending process, further improving the bending quality. It is also suitable for inductor coil bodies 8 with different inner diameter specifications, increasing the functionality of the bending machine body 1.

[0031] The guide post 4 has an insert post 23 that is slidably connected inside, and the surface of the insert post 23 is fixedly mounted with an inclined block 24 that matches the inclined groove 19.

[0032] One end of the second spring 22 is fixedly connected to the inner side of the slider 18, and the other end of the second spring 22 is fixedly connected to the surface of the fixing plate 20.

[0033] The bottom surface of the guide post 4 is threaded with a threaded rod 25, and the bottom surface of the insertion post 23 is rotatably connected with a rotating ring 27. One end of the threaded rod 25 is rotatably connected to the insertion post 23 through the rotating ring 27, and the other end of the threaded rod 25 is fixedly connected with a knob 26. The design of the threaded rod 25 makes the movement of the insertion post 23 more stable.

[0034] The steps of using this utility model are as follows: When using this inductor coil lead bending machine, there are many types of inductor coil bodies 8 in daily life, and the inner diameter specifications of the inductor coil body 8 are also different. By rotating the knob 26, the threaded rod 25 is rotated inside the guide post 4. At this time, the insert 23 moves upward inside the guide post 4, which causes the inclined block 24 to move and squeeze the inclined groove 19. The slider 18 moves outward from the guide post 4. At this time, the second spring 22 is stretched. When the surface of the slider 18 contacts the inner diameter of the inductor coil body 8, the rotation of the threaded rod 25 stops. This scheme uses the insert 23 to move upward inside the guide post 4, which causes the inclined block 24 to move and squeeze the inclined groove 19. At this time, the slider 18 moves outward from the guide post 4. When the surface of the slider 18 contacts the inner diameter of the inductor coil body 8, the surface of the slider 18 is used to guide the inductor coil body 8 during the downward movement process, preventing the lead wire 9 from shaking during the bending process, further improving the bending quality. It is also applicable to inductor coil bodies 8 with different inner diameter specifications, increasing the functionality of the bending machine body 1.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
