Description

Technical Field

[0001] The invention relates to the technical field of transformer manufacturing equipment, in particular to a transformer manufacturing casting material casting equipment which is convenient for eliminating bubbles. Background Art

[0002] A transformer is an electrical device used primarily for measuring, protecting, and controlling voltage and current in power systems. It uses the principle of electromagnetic induction to convert high voltage or high current into low voltage or low current, facilitating measurement and protecting the safe operation of equipment.

[0003] In the manufacturing process of the transformer, casting is a key step, which directly affects the quality and performance of the transformer. Traditional casting equipment has some problems in the casting process. For example, it is difficult to completely eliminate bubbles in the casting material, resulting in pores inside the transformer, affecting its insulation performance and mechanical strength. In addition, the uneven density of the casting material will also lead to the performance degradation of the transformer. During the casting process, if the flow of the casting material is unstable, it may also cause incomplete local casting, affecting the overall structural integrity of the transformer. Summary of the Invention

[0004] The present invention provides a casting material pouring device for mutual inductor manufacturing that is convenient for eliminating bubbles, and solves the problems mentioned in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A casting material pouring device for mutual inductor manufacturing that facilitates bubble elimination, comprising a buffer tube, a connecting ring fixedly mounted on the outer surface of the buffer tube, a top cover fixedly connected to the top inner surface of the buffer tube, a bottom cover fixedly connected to the bottom inner surface of the buffer tube, the bottom cover and the top cover being arranged horizontally with each other, and further comprising: A pouring mechanism, the pouring mechanism is fixedly mounted on the buffer tube, the bottom of the pouring mechanism is arranged directly below the buffer tube, and the pouring mechanism is used to pour the mutual inductor; An auxiliary mechanism, the auxiliary mechanism being fixedly mounted on the pouring mechanism and being used to cooperate with the pouring mechanism to work; The pouring mechanism includes a feed pipe, the bottom of which is fixedly connected to the middle upper surface of the bottom cover, the top of which is passed through and fixedly connected to the middle upper surface of the top cover, a feed trough is passed through the outer surface of the bottom of the feed pipe, and six feed troughs are arranged at fixed intervals around the central axis of the feed pipe, a limiting flow ring is provided on the outer side of the bottom of the feed pipe, the inner bottom surface of the limiting flow ring is fixedly connected to the middle upper surface of the bottom cover, the diameter of the limiting flow ring is smaller than the diameter of the bottom cover, a discharge trough is provided below the limiting flow ring, the discharge trough is passed through and opened on the upper surface of the bottom cover, and three discharge troughs are arranged at fixed intervals around the central axis of the bottom cover.

[0006] The upper surface of the current limiting ring is fixedly connected with a sliding rod, the top of the sliding rod is fixedly connected to the inner surface of the top cover, and three sliding rods are arranged at fixed intervals around the central axis of the current limiting ring, and the sliding rod is arranged in a cavity between the feed pipe and the inner wall of the cache tube, and a pressure plate is connected to the sliding rod by sliding up and down through a spring. The pressure plate is initially located on the side of the sliding rod close to the bottom cover. When the mutual inductor needs to be cast, the device can be installed above the mold through the connecting ring, and the casting material is continuously injected into the feed pipe after the installation is completed. When the casting material continuously fills the feed pipe, as the pressure is continuously injected, the casting material will enter the cache through the feed trough at the bottom of the feed pipe. In the tube, when the castable enters the cache tube, it will be filled between the flow limiting ring and the pressure plate through the feed trough, and with the continuous injection, the pressure of the castable between the flow limiting ring and the pressure plate will increase, thereby generating an extrusion force on the pressure plate, causing the pressure plate to move upward along the slide rod under the action of elastic force, thereby increasing the cavity between the flow limiting ring and the pressure plate and increasing the capacity for the castable.

In addition, the castable entering the cache tube can only be output to the bottom cover through the gap between the flow limiting ring and the cache tube.

[0010] Preferably, a blocking ring is fixedly connected to the top outer surface of the guide tube, and the blocking ring is arranged above the micropore. An air outlet is arranged above the blocking ring, and the air outlet is opened through the top outer surface of the filter tube. Six air outlets are arranged at fixed intervals around the central axis of the filter tube, and a breathable plug is arranged in the air outlet. When the castable passes through the discharge trough, it will enter the guide tube and be spirally output outward through the spiral plate installed in the guide tube. Pressurized spiral conveying is realized in conjunction with the pressure plate and the current limiting ring, which can not only further improve the stable conveying effect of the castable, but also further ensure that there will be no castable vacancies in the mold, thereby greatly improving the casting effect of the mutual inductor.

[0011] Preferably, the auxiliary mechanism includes a mounting cover, the top outer surface of the mounting cover is fixedly connected to the bottom surface of the filter tube, the bottom of the mounting cover is fixedly connected to a pouring bucket, a connecting groove is opened through the upper surface of the mounting cover, the diameter of the connecting groove is the same as the inner diameter of the filter tube, the bottom of the filter tube is buckled above the connecting groove, and three connecting grooves are opened at fixed intervals around the central axis of the mounting cover.

[0012] Preferably, the bottom inner surface of the mounting cover is fixedly connected with a support rod, the outer surface of the support rod is slidably connected with a guide plate, the guide plate is evenly provided with guide holes, the side of the guide plate is fitted on the inner surface of the mounting cover, the upper surface edge of the guide plate is fixedly connected with a telescopic rod, three telescopic rods are arranged at fixed intervals around the central axis of the guide plate, and the top of the telescopic rod is fixedly connected to the bottom surface of the pressure plate.

[0013] Preferably, the support rod is configured as a threaded rod, the outer surface of the support rod is connected to a rotating ring through a thread, the bottom of the rotating ring is rotatably connected to the upper surface of the guide plate, the outer surface of the rotating ring is fixedly connected to a fluctuating plate, the fluctuating plate is configured as an arc, the middle bottom surface of the guide plate is fixedly connected to an inner ring, the bottom of the inner ring is elastically plugged with an outer ring, the bottom of the outer ring is fixedly connected to the bottom of the support rod, when the castable passes through the guide pipe, it will enter the mounting cover, and exist in the gap between the mounting cover and the guide plate, and finally enter the pouring bucket through the guide hole on the guide plate, and be transported to the mold through the pouring bucket to complete the pouring.

[0014] The present invention provides a casting material pouring device for mutual inductor manufacturing that facilitates bubble elimination and has the following beneficial effects: 1. This transformer manufacturing casting material pouring equipment, which is easy to eliminate bubbles, can automatically pressurize the casting material after it enters the equipment through the cooperation of the pressure plate and the current limiting ring, thereby greatly increasing the density of the casting material and squeezing out the bubbles inside it, that is, greatly improving the product quality of the transformer after pouring. At the same time, by automatically pressurizing the casting material, the continuous pouring stability of the casting material can be guaranteed, ensuring that the casting material will not have a local flow interruption that leads to incomplete pouring.

[0015] 2. The mutual inductor manufacturing casting material pouring equipment that is easy to eliminate bubbles can further help eliminate bubbles in the casting material through the spiral conveying method, reduce the air gap generated during the pouring process, and the spiral conveying and pouring method can also make the equipment suitable for molds of complex shapes, ensuring that the casting material can be fully filled in the mold, greatly improving the applicability of the equipment, and the spiral pressurized conveying can also greatly reduce the pouring time, greatly improving the production efficiency. At the same time, when the casting material is conveyed in the guide tube, the squeezed bubbles will be discharged into the filter tube through the micropores and discharged to the outside through the air outlet on the filter tube, realizing automatic elimination of bubbles during pouring, greatly improving the working integration effect of the equipment and further improving production efficiency.

[0016] 3. This transformer manufacturing casting material pouring equipment that is easy to eliminate bubbles can ensure that the casting material passing through the pouring bucket is in a straight line conveying state by setting a guide plate and a guide hole before pouring. The straight line pouring can more directly introduce the casting material into the mold, reduce the flow distance and flow resistance, thereby further improving the filling efficiency. At the same time, the straight line pouring in the last stage of conveying can make it easier for bubbles to escape, which helps to further reduce the generation of bubbles during the pouring process, reduce the air holes of the transformer after pouring, and improve the overall quality of the product. At the same time, when local pouring occurs in the installation cover When the material accumulates, the amount of castable passing through the drainage holes on the drainage plate will be greatly reduced. At this time, the output speed of the castable is further restricted, thereby further increasing the pressure of the castable in the installation cover. Under the action of pressure, the drainage plate will be pushed downward for buffering. As the drainage plate moves downward, the rotating ring will start to rotate under the action of the thread, thereby driving the fluctuation plate to rotate. That is, when the drainage plate moves downward, the fluctuation plate starts to rotate to stir and dredge the castable above the drainage plate, which greatly improves the working stability of the equipment and avoids internal blockage and reduces the casting quality.

[0017] 4. The mutual inductor manufacturing casting material pouring equipment which is convenient for eliminating bubbles, will cause the telescopic rod to be stretched when the pressure plate rises and expands, and the displacement amplitude of the pressure plate is limited by the telescopic rod to ensure the internal pressure of the equipment during pouring. When the pressure plate drives the telescopic rod to be pulled to the maximum extension amount, if the drainage plate is blocked, it can further prevent the pressure plate from moving up to reduce the casting material pressure in the installation cover, and ensure that the drainage plate can be accurately and effectively cleared when the casting material accumulates, thereby further improving the working stability of the equipment.

Auxiliary mechanism 6, the auxiliary mechanism 6 is fixedly mounted on the pouring mechanism 5, and the auxiliary mechanism 6 is used to cooperate with the pouring mechanism 5 to work; The pouring mechanism 5 includes a feed pipe 51, the bottom of which is fixedly connected to the middle upper surface of the bottom cover 4, the top of which is fixedly connected to the middle upper surface of the top cover 3, a feed trough 52 is provided on the outer surface of the bottom of the feed pipe 51, and six feed troughs 52 are arranged at fixed intervals around the central axis of the feed pipe 51, a limiting flow ring 53 is provided on the outer side of the bottom of the feed pipe 51, and the inner bottom surface of the limiting flow ring 53 is fixedly connected to the middle upper surface of the bottom cover 4, the diameter of the limiting flow ring 53 is smaller than that of the bottom cover 4, and a discharge trough 54 is provided below the limiting flow ring 53, the discharge trough 54 is provided on the upper surface of the bottom cover 4, and three discharge troughs 54 are arranged at fixed intervals around the central axis of the bottom cover 4.

[0022] The upper surface of the current limiting ring 53 is fixedly connected to a slide rod 55, the top of the slide rod 55 is fixedly connected to the inner surface of the top cover 3, three slide rods 55 are arranged at fixed intervals around the central axis of the current limiting ring 53, the slide rod 55 is arranged in the cavity between the feed pipe 51 and the inner wall of the cache tube 1, and the slide rod 55 is connected to a pressure plate 56 by a spring to slide up and down. The pressure plate 56 is initially located on the slide rod 55 on the side close to the bottom cover 4.

[0023] During operation, when the mutual inductor needs to be cast, the device can be installed above the mold through the connecting ring 2, and after the installation is completed, the casting material is continuously injected into the feed pipe 51. When the casting material continuously fills the feed pipe 51, as the pressure is continuously injected, the casting material will enter the buffer tube 1 through the feed groove 52 at the bottom of the feed pipe 51. When the casting material enters the buffer tube 1, it will pass through the feed groove 52 to fill the space between the flow limiting ring 53 and the pressure plate 56, and as the injection is continued, the pressure of the casting material between the flow limiting ring 53 and the pressure plate 56 will increase, thereby generating an extrusion force on the pressure plate 56, causing the pressure plate 56 to move upward along the slide rod 55 under the action of the elastic force, thereby increasing the cavity between the flow limiting ring 53 and the pressure plate 56 to improve the capacity of the casting material. amount, and the castable in the cache tube 1 is in a high-pressure state at this time. In addition, the castable can only be output to the bottom cover 4 through the gap between the flow-limiting ring 53 and the cache tube 1 after entering the cache tube 1.

At the same time, by automatically pressurizing the castable, the continuous casting stability of the castable can be guaranteed, ensuring that the castable will not have local flow interruption and cause incomplete casting.

[0024] Second embodiment: Figures 1 to 8 As shown, a filter tube 57 is fixedly connected to the bottom surface of the bottom cover 4. Three filter tubes 57 are arranged at fixed intervals around the central axis of the bottom cover 4. The top surface of the filter tube 57 is buckled into the bottom of the discharge trough 54. The diameter of the filter tube 57 is larger than the diameter of the discharge trough 54.

[0025] A guide tube 58 is provided inside the filter tube 57. The guide tube 58 and the filter tube 57 are set to the same central axis. The diameter of the guide tube 58 is the same as the diameter of the discharge trough 54. The guide tube 58 is connected to the discharge trough 54. The guide tube 58 and the filter tube 57 are set to be of equal length. The top of the guide tube 58 is fixedly connected to the lower surface of the bottom cover 4.

[0026] The interior of the guide tube 58 is fixedly connected to a spiral plate 59 , and the outer surface of the guide tube 58 is penetrated by micropores 510 . A plurality of micropores 510 are arranged at fixed intervals around the outer surface of the guide tube 58 , and the inner sides of the micropores 510 are arranged between the spiral plates 59 .

[0027] A blocking ring 511 is fixedly connected to the top outer surface of the guide tube 58. The blocking ring 511 is arranged above the micropore 510. An air outlet hole 512 is arranged above the blocking ring 511. The air outlet hole 512 is opened through the top outer surface of the filter tube 57. There are six air outlet holes 512 arranged at fixed intervals around the central axis of the filter tube 57, and a ventilation plug is provided in the air outlet hole 512.

[0028] During operation, after the castable passes through the discharge chute 54, it enters the guide tube 58 and is spirally output outward through the spiral plate 59 installed in the guide tube 58. The pressure plate 56 and the flow-limiting ring 53 are used to realize pressurized spiral conveying, which can not only further improve the stable conveying effect of the castable, but also further ensure that there will be no castable gaps in the mold, greatly improving the casting effect of the mutual inductor. At the same time, the spiral conveying method can further help eliminate bubbles in the castable and reduce the air gap generated during the casting process. The spiral conveying and pouring method can also make the present device suitable for molds of complex shapes, ensuring that the castable can be fully filled in the mold, greatly improving the applicability of the present device, and the spiral pressurized conveying can also greatly shorten the casting time and greatly improve the production efficiency. At the same time, when the castable is conveyed in the guide tube 58, the squeezed bubbles will be discharged into the filter tube 57 through the micropores 510 and discharged outward through the air outlet 512 on the filter tube 57, realizing automatic elimination of bubbles during casting, greatly improving the working integration effect of the present device and further improving production efficiency.

[0029] The third embodiment: Figures 1 to 8 As shown, the auxiliary mechanism 6 includes a mounting cover 61, the top outer surface of the mounting cover 61 is fixedly connected to the bottom surface of the filter tube 57, the bottom of the mounting cover 61 is fixedly connected to a pouring bucket 62, and a connecting groove 63 is opened through the upper surface of the mounting cover 61. The diameter of the connecting groove 63 is the same as the inner diameter of the filter tube 57, and the bottom of the filter tube 57 is buckled on the top of the connecting groove 63. There are three connecting grooves 63 at fixed intervals around the central axis of the mounting cover 61.

[0030] The bottom inner surface of the mounting cover 61 is fixedly connected to a support rod 64, and the outer surface of the support rod 64 is slidably connected to a guide plate 65, on which guide holes 66 are evenly opened. The side of the guide plate 65 is attached to the inner surface of the mounting cover 61, and the upper surface edge of the guide plate 65 is fixedly connected to a telescopic rod 67. Three telescopic rods 67 are arranged at fixed intervals around the central axis of the guide plate 65, and the top of the telescopic rod 67 is fixedly connected to the bottom surface of the pressure plate 56.

[0031] The support rod 64 is configured as a threaded rod, and the outer surface of the support rod 64 is connected to a rotating ring 68 through a thread. The bottom of the rotating ring 68 is rotatably connected to the upper surface of the guide plate 65. The outer surface of the rotating ring 68 is fixedly connected to a fluctuating plate 69, and the fluctuating plate 69 is configured to be arc-shaped. The middle bottom surface of the guide plate 65 is fixedly connected to an inner ring 610, and the bottom of the inner ring 610 is elastically inserted with an outer ring 611, and the bottom of the outer ring 611 is fixedly connected to the bottom of the support rod 64.

[0032] During operation, after the castable passes through the guide tube 58, it will enter the installation cover 61 and exist in the gap between the installation cover 61 and the guide plate 65, and finally enter the pouring bucket 62 through the guide hole 66 on the guide plate 65, and be transported to the mold through the pouring bucket 62 to complete the pouring. By arranging the guide plate 65 and the guide hole 66 before pouring, it can be ensured that the castable passing through the pouring bucket 62 is in a straight line conveying state. Straight line pouring can more directly introduce the castable into the mold, reduce the flow distance and flow resistance, thereby further improving the filling efficiency. At the same time, in the final stage of conveying, straight line pouring can make it easier for bubbles to escape, which helps to further reduce the generation of bubbles during the pouring process, reduce the air holes in the mutual inductor after the pouring is completed, and improve the overall quality of the product. At the same time, when local castable accumulation occurs in the installation cover 61, the castable passing through the guide hole 66 on the guide plate 65 will be greatly reduced. At this time, the output speed of the castable is further restricted, thereby further improving The pressure of the castable in the installation cover 61 will push the guide plate 65 downward to provide buffering under the action of pressure. As the guide plate 65 moves downward, the rotating ring 68 will start to rotate under the action of the thread, thereby driving the fluctuating plate 69 to rotate. That is, when the guide plate 65 moves downward, the fluctuating plate 69 starts to rotate to stir and dredge the castable above the guide plate 65, greatly improving the working stability of the equipment and avoiding internal blockage and reducing the casting quality. When the pressure plate 56 rises and expands, the telescopic rod 67 will be stretched, and the displacement amplitude of the pressure plate 56 is limited by the telescopic rod 67 to ensure the internal pressure of the equipment during casting. When the pressure plate 56 drives the telescopic rod 67 to be pulled to the maximum extension amount, if the guide plate 65 is blocked, it can further prevent the pressure plate 56 from moving upward to reduce the castable pressure in the installation cover 61, ensuring that the guide plate 65 can be accurately and effectively dredged when castable accumulation occurs, further improving the working stability of the equipment.
