Description

Technical Field

[0001] This invention relates to the field of permanent magnet component manufacturing technology, specifically to a production apparatus for permanent magnet components of switching equipment and its usage method. Background Technology

[0002] In the production process of ferrite permanent magnet components, a press is required to extrude and form them. However, when existing presses extrude ferrite permanent magnet components, the ferrite easily generates high heat after being pressed, making it inconvenient for workers to handle and causing them to burn their hands. In a high-performance permanent magnet component production equipment and method of use with application number CN202110113765.6, a flip-up pressure seat is provided, which allows the component to automatically detach from the pressure seat and fall into a cooling box for cooling. This can prevent the component from burning workers and greatly improve its practicality.

[0003] While this device possesses the aforementioned advantages, it still suffers from the following drawbacks in practical use:

[0004] 1) Although the device causes the ferrite permanent magnet to fall off and cool down automatically by rotating the pressure seat, the pressure seat needs to be rotated repeatedly during continuous processing, which affects the overall processing efficiency.

[0005] 2) After the device cools down the ferrite permanent magnet components by cooling water, it is necessary to dry and transfer them, which makes the overall processing time-consuming and labor-intensive and further reduces the processing efficiency.

[0006] Therefore, it is necessary to address the shortcomings of existing permanent magnet component production equipment. Summary of the Invention

[0014] Preferably, a ratchet is fixedly connected through the outer surface of the transmission rod, and the outer surface of the ratchet is fixedly connected through the body of the drive gear. A torsion spring is sleeved on the outside of the transmission rod, and the two ends of the torsion spring are fixedly connected to the outer surfaces of the bracket and the drive gear, respectively.

[0015] Preferably, a limiting groove is formed on the outer surface of the rack, a limiting strip is slidably connected inside the limiting groove, and the outer surface of the limiting strip is fixedly connected to the outer surface of the bracket.

[0016] Preferably, the vibrating conveyor is provided with a spraying unit on its exterior. The spraying unit includes a water storage tank. The outer surface of the water storage tank is fixedly connected to the outer surface of the vibrating conveyor. The interior of the water storage tank is connected to the interior of the drain outlet. A water supply pipe runs through the interior of the water storage tank. A water distribution pipe runs through one end of the water supply pipe. A spraying pipe runs through the interior of the water distribution pipe. A spraying head runs through the interior of the spraying pipe. The spraying head is positioned directly above the rotating roller.

[0017] Preferably, the water supply pipe is rotatably connected to a blade, and the shaft end of the blade is fixedly connected to a drive rod. The outer surface of the drive rod is rotatably connected to the inside of the water storage tank. One end of the drive rod is rotatably connected to the body of the water storage tank and extends to the outside of the water storage tank. A transmission belt is provided on the outside of the drive rod. Two transmission wheels are rotatably connected to the outer surface of the transmission belt. The bodies of the two transmission wheels are respectively fixedly connected to the outer surface of the transmission rod and the input end of the vibration mechanism of the vibrating conveyor.

[0018] This invention also discloses a method for using a production apparatus for permanent magnet components of switching devices, specifically including the following steps:

[0019] Step 1: Place the ferrite permanent magnet component to be processed on the pressure seat of the processing table, and then extrude it through the cylinder and pressure plate. The rotating cylinder drives the arc plate and electromagnet to rotate through the rotating rod and the circular plate. When the electromagnet is directly above the pressure seat, it is energized to generate magnetism. The processed ferrite permanent magnet component is attracted and picked up by the magnetic force, and is automatically unloaded along with the rotation.

[0020] Step 2: When the ferrite permanent magnet element is transferred to the top of the vibrating conveyor, the electromagnet is de-energized and demagnetized, causing the ferrite permanent magnet element to fall onto the rotating roller. As the rotating rod rotates, the rack slides through the lever and vertical bar. The rack drives the drive gear to rotate and compresses the torsion spring. After the lever and vertical bar are disengaged, the torsion spring drives the drive gear to reverse and drives the transmission rod to rotate through the ratchet. Through the transmission of the transmission gear and the rotating gear, the vibrating conveyor works to transport the ferrite permanent magnet element. During the transport process, the element is cooled and dehydrated by spraying.

[0021] Step 3: When the vibrating conveyor is conveying the ferrite permanent magnet components, the drive rod drives the blades to rotate through the transmission wheel and transmission belt. This pumps the liquid water inside the water tank into the spray pipe through the water supply pipe and the water distribution pipe. The spray head then sprays the ferrite permanent magnet components to cool them down. The sprayed liquid water is then dislodged by vibration and flows back into the water tank through the baffle plate and the drain outlet.

[0022] Beneficial effects

[0023] This invention provides a production apparatus for permanent magnet components in switching devices and a method for using them. Compared with the prior art, it has the following advantages:

[0024] (1) By setting up a material picking mechanism, the circular plate drives the arc plate and electromagnet to rotate. After the ferrite permanent magnet element is processed, it can be automatically picked up and transferred by magnetic force, thereby avoiding the problem of repeated rotation of the pressure seat reducing the continuous processing efficiency. At the same time, by covering the pressure seat with the spacing of two adjacent arc plates, it is also convenient to continuously process the ferrite permanent magnet element, thereby further improving the overall processing efficiency.

[0025] (2) By setting up a material conveying assembly, the lever follows the rotation of the circular plate, thereby causing the rack to slide. Through the action of the ratchet and the rebound of the torsion spring, the vibrating conveyor automatically conveys the ferrite permanent magnet element by vibration after it is placed on the rotating roller. During the conveying process, liquid water is used to cool it down. The rotating roller can reduce sliding wear and facilitate the removal and recycling of liquid water through its own gap, thereby reducing the waste of liquid water and reducing the number of operation steps, thus further improving the processing efficiency.

[0026] (3) By setting up a spray unit, liquid water can be stored in a water storage tank, which facilitates the recycling of liquid water, thereby reducing the waste of liquid water and achieving energy saving and environmental protection. Furthermore, by utilizing the transmission effect of the transmission belt, the vibrating conveyor can spray the ferrite permanent magnet components simultaneously while conveying them. Moreover, by utilizing the function of the water distribution pipe, the spray pipes are distributed on the conveying channel, thereby increasing the spraying time to improve the cooling efficiency and effect.

[0033] 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.

[0034] Please see Figure 1-5 This invention provides a technical solution: a production apparatus for permanent magnet components of switching devices.

[0035] Example 1: The system includes a processing table 1, which comprises a housing, a pressure base, and a pressure plate driven by a cylinder and positioned directly above the pressure base. A material handling mechanism is provided on the outside of the processing table 1. This mechanism includes a rotary cylinder 2, which is electrically connected to an external control circuit and has a fixed rotation angle. The outer surface of the rotary cylinder 2 is fixedly connected to the outer surface of the processing table 1. A rotating rod 3 is fixedly connected to the output end of the rotary cylinder 2, and a circular plate 4 is fixedly connected to one end of the rotating rod 3. Preferably, a rotary contact is coaxially arranged on the top of the circular plate 4. The component, used for electrical connection with external control circuit, has an arc plate 5 on its outer surface. Multiple arc plates 5 are arranged at equal angles around the axis of the circular plate 4. The distance between two adjacent arc plates 5 is greater than the width of the pressure seat of the processing table 1, so as to avoid affecting the continuous processing of the ferrite permanent magnet component by the processing table 1 when the arc plate 5 stops. An electromagnet 7 is embedded and fixedly connected to the body of the arc plate 5. The electromagnet 7 is electrically connected to the external control circuit and automatically picks up the ferrite permanent magnet component after extrusion processing by magnetic force, thereby avoiding the risk of burns from manual handling. The problem is that the electromagnet 7 rotates with the circular plate 4 via the arc plate 5, and when it rotates to directly above the pressure seat, it magnetically attracts the processed ferrite permanent magnet element, achieving continuous feeding without flipping. The outer arc surface of the circular plate 4 has a groove 8, and a slider 9 is slidably connected inside the groove 8. The body of the slider 9 is slidably connected to a slide rod 10, which can limit and guide the slider 9. The slider 9 can monitor whether the ferrite permanent magnet element is picked up by sliding up and down with the arc plate 5. The end of the slide rod 10 is fixed inside the groove 8. The slider 10 is connected to a spring 11, which is sleeved on the outside of the slider 9. The spring 11 facilitates the reset of the slider 9 after sliding. The two ends of the spring 11 are fixedly connected to the outer surface of the slider 9 and the inside of the groove 8, respectively. A spotlight 12 is fixedly connected to the inside of the groove 8 and is electrically connected to the external control circuit. A photosensitive plate 13 is fixedly connected to the outer surface of the slider 9 and is electrically connected to the external control circuit. The photosensitive plate 13 is made of photosensitive material and its resistance value will change after being exposed to light. The outer surface of the photosensitive plate 13 is slidably connected to the inside of the groove 8.

[0036] In this embodiment, the ferrite permanent magnet element to be processed is placed on the pressure seat of the processing table 1. Then, the cylinder drives the pressure plate to move, and through the gap between two adjacent arc plates 5, it cooperates with the pressure seat to extrude the ferrite permanent magnet element. After processing, the rotary cylinder 2 drives the arc plate 5 to rotate at a preset angle through the rotating rod 3 and the circular plate 4. When the arc plate 5 drives the electromagnet 7 to move directly above the pressure seat, the electromagnet 7 is energized and magnetized, thereby picking up the processed ferrite permanent magnet element through magnetic attraction. Then, with the rotation, the ferrite permanent magnet element is detached from the pressure seat, allowing for continuous processing. During the movement, under the influence of the gravity of the ferrite permanent magnet element itself, the arc plate 5 drives the slider 9 to move downward. The slider 9 drives the photosensitive plate 13 to descend along the slide rod 10 inside the groove 8, and compresses the spring. During the compression process, the processed ferrite permanent magnet element is transferred from the pressure base to the unloading station. It undergoes multiple rotations and pauses, allowing for heat dissipation using air. Simultaneously, if the photosensitive plate 13 is lowered by gravity, it will receive rays from the spotlight 12. By analyzing changes in its own resistance and circuit current, a monitoring signal is generated to determine whether the processed ferrite permanent magnet element has been picked up and whether it has fallen off during transport. If it is not picked up, the arc plate 5 is rotated again to pick it up, and the current of the electromagnet 7 is increased simultaneously to increase the magnetic force and ensure the ferrite permanent magnet element is picked up. If a problem occurs with the ferrite permanent magnet element during multiple rotations and pauses, a corresponding alarm signal is generated, and the operator manually picks it up.

[0037] Example 2: A material conveying assembly 6 is provided on the outside of the arc plate 5. The material conveying assembly 6 includes a vibrating conveyor 61, which is made of GZG series vibrating feeder and installed on an external support (not shown in the figure). The vibrating conveyor 61 is located below the arc plate 5. The frame of the vibrating conveyor 61 is rotatably connected to a support rod 62. A rotating roller 63 is fixedly connected to the outer surface of the support rod 62. A certain gap is set between two adjacent rotating rollers 63, and the distance between their support points is smaller than the size of the ferrite permanent magnet element. The body of the vibrating conveyor 61 has a drain outlet 65, which facilitates the discharge of liquid water after spraying and avoids waste caused by liquid water contamination on the vibrating conveyor 61. A baffle plate 66 is fixedly connected to the outer surface of the vibrating conveyor 61. The baffle plate 66 can block the liquid water after spraying so that it can be discharged through the drain port 65. A rotating gear 67 is fixedly connected to the input end of the vibration mechanism of the vibrating conveyor 61. A transmission gear 68 meshes with the outer surface of the rotating gear 67. Both the transmission gear 68 and the rotating gear 67 are made of bevel gears. A transmission rod 69 is fixedly connected to the outer surface of the transmission gear 68. A bracket 610 is rotatably connected through the outer surface of the transmission rod 69. The outer surface of the bracket 610 is fixedly connected to the outer surface of the processing table 1. A drive gear 611 is fixedly connected through the outer surface of the transmission rod 69. A rack 612 meshes with the outer surface of the drive gear 611. A vertical bar 613 is fixedly connected to the outer surface of the rack 612. A lever 614 is movably connected to the outer surface of the vertical bar 613. During rotation, the lever 614 can push the vertical bar 613 to slide the rack 612 by changing the position of one end. It can also disengage from the vertical bar 613 during rotation, thus achieving continuous drive and cyclical use of power for the rotary cylinder 2. One end of the lever 614 is fixedly connected to the outer surface of the rotating rod 3. A ratchet 615 is fixedly connected through the outer surface of the transmission rod 69. The ratchet 615 allows the rack 612 to drive the drive gear 611 to rotate independently when pushed. The outer surface of the ratchet 615 is fixedly connected through the body of the drive gear 611. The outer surface of the transmission rod 69... A torsion spring 616 is fitted, and the torsion spring 616, after being compressed, causes the drive gear 611 to drive the transmission rod 69 to rotate through the ratchet 615, thereby realizing the power transmission. The two ends of the torsion spring 616 are fixedly connected to the bracket 610 and the outer surface of the drive gear 611, respectively. A limit groove 617 is opened on the outer surface of the rack 612, and a limit strip 618 is slidably connected inside the limit groove 617. The cross-section of the limit strip 618 is T-shaped, which improves the stability and force bearing of the rack 612 through the action of the bracket 610. At the same time, the movement of the rack 612 can be guided by the cooperation of the limit strip 618 and the limit groove 617. The outer surface of the limit strip 618 is fixedly connected to the outer surface of the bracket 610.

[0038] In this embodiment, the rotating rod 3 drives the arc plate 5 to rotate, which in turn drives the lever 614 to rotate synchronously. Before the electromagnet 7 drives the ferrite permanent magnet element to move above the vibrating conveyor 61, the lever 614 first contacts the vertical bar 613, thereby causing the rack 612 to slide during rotation. The rack 612, through meshing with the drive gear 611 and through the action of the ratchet 615, drives the drive gear 611 to rotate independently and compresses the torsion spring 616. When the electromagnet 7 drives the ferrite permanent magnet element to move above the vibrating conveyor 61, the lever 614 disengages from the vertical bar 613, and the electromagnet 7 is de-energized and retracts. The magnet causes the ferrite permanent magnet element to fall onto the rotating roller 63. At the same time, the torsion spring 616 rebounds, driving the drive gear 611 to rotate. This causes the transmission rod 69 to rotate through the ratchet pawl of the ratchet 615. Then, through the meshing of the rotating gear 67 and the transmission gear 68, the vibration mechanism of the vibrating conveyor 61 is activated, thus conveying the ferrite permanent magnet element. During the conveying process, the element is sprayed with water to cool it down. The sprayed liquid water is discharged through the drain outlet 65 through the baffle plate 66. Meanwhile, the sprayed ferrite permanent magnet element is dehydrated by vibration, achieving its own drying for subsequent transfer, storage, or reprocessing.

[0039] Example 3: A spray unit 64 is provided on the outside of the vibrating conveyor 61. The spray unit 64 includes a water storage tank 641, which can store and recycle the sprayed liquid water, realizing the recycling of liquid water, thereby reducing loss and waste. At the same time, the spray range is smaller than the distance between the landing point of the ferrite permanent magnet element and the drain outlet 65, so as to provide space for the dehydration of the ferrite permanent magnet element, and facilitate the collection and discharge of the liquid water falling off the vibrator by the drain outlet 65. The outer surface of the water storage tank 641 is in contact with the vibrating... The outer surface of the conveyor 61 is fixedly connected to the interior of the water tank 641, which is connected to the interior of the drain outlet 65. A water supply pipe 642 runs through the interior of the water tank 641. One end of the water supply pipe 642 is connected to a water distribution pipe 643. The axis of the water distribution pipe 643 is parallel to the conveying direction of the vibrating conveyor 61, allowing for the diversion of liquid water and thus increasing the spraying range. A spray pipe 644 runs through the interior of the water distribution pipe 643, and a spray head 645 runs through the interior of the spray pipe 644. The spraying range of the spray head 645 covers the axial length of the rotating roller 63, thereby avoiding leakage and waste of liquid water during spraying. The spray head 645 is positioned directly above the rotating roller 63. A paddle 646 is rotatably connected inside the water supply pipe 642. The paddle 646 can pump liquid water for spraying by rotating. A drive rod 647 is fixedly connected to the shaft end of the paddle 646. The outer surface of the drive rod 647 is rotatably connected to the inside of the water storage tank 641. One end of the drive rod 647 is rotatably connected to the body of the water storage tank 641 and extends through it. Outside the water storage tank 641, a transmission belt 648 is provided on the outside of the drive rod 647. Two transmission wheels 649 are connected to the outer surface of the transmission belt 648. The transmission of the transmission wheels 649 and the transmission belt 648 enables the conveying of ferrite permanent magnet elements and spray cooling to be carried out simultaneously, which not only realizes the recycling of power, but also avoids the waste of liquid water and power. The bodies of the two transmission wheels 649 are respectively fixedly connected to the outer surface of the transmission rod 69 and the input end of the vibration mechanism of the vibrating conveyor 61.

[0040] In this embodiment, when the vibration mechanism of the vibrating conveyor 61 is working to convey the ferrite permanent magnet element, the drive rod 647 drives the blade 646 to rotate through the transmission action of the transmission belt 648 and the transmission wheel 649. This causes the blade 646 to pump the liquid water inside the water storage tank 641 into the spray pipe 644 through the water supply pipe 642 and the water distribution pipe 643. The water is then sprayed onto the ferrite permanent magnet element through the spray head 645, thereby achieving simultaneous conveying and spray cooling. After the ferrite permanent magnet element is sprayed and cooled, it can be automatically dehydrated by the vibration conveying, which also reduces the waste of liquid water.

[0041] This invention also discloses a method for using a production apparatus for permanent magnet components of switching devices, specifically including the following steps:

[0042] Step 1: Place the ferrite permanent magnet component to be processed on the pressure seat of the processing table 1, and then extrude it through the cylinder and pressure plate. Subsequently, the rotating cylinder 2 drives the arc plate 5 and electromagnet 7 to rotate through the rotating rod 3 and the circular plate 4. When the electromagnet 7 is directly above the pressure seat, it is energized to generate magnetism. The processed ferrite permanent magnet component is attracted and picked up by the magnetic force, and the component is automatically unloaded along with the rotation.

[0043] Step 2: When the ferrite permanent magnet element is transferred to the top of the vibrating conveyor 61, the electromagnet 7 is de-energized and demagnetized, causing the ferrite permanent magnet element to fall onto the rotating roller 63. When the rotating rod 3 rotates, the rack 612 is moved to slide by the lever 614 and the vertical bar 613. The rack 612 drives the drive gear 611 to rotate and compresses the torsion spring 616. After the lever 614 and the vertical bar 613 are disengaged, the torsion spring 616 drives the drive gear 611 to reverse and drives the transmission rod 69 to rotate through the ratchet 615. Through the transmission of the transmission gear 68 and the rotating gear 67, the vibrating conveyor 61 works to transport the ferrite permanent magnet element. During the transport process, the element is cooled and dehydrated by spraying.

[0044] Step 3: When the vibrating conveyor 61 conveys the ferrite permanent magnet element, the drive rod 647 drives the blade 646 to rotate through the transmission wheel 649 and the transmission belt 648, so as to pump the liquid water inside the water storage tank 641 into the spray pipe 644 through the water supply pipe 642 and the water distribution pipe 643, and spray the ferrite permanent magnet element to cool it down through the spray head 645. The sprayed liquid water is dislodged by vibration and flows back into the water storage tank 641 through the action of the baffle plate 66 and the drain outlet 65.
