Technical Field

[0001] The invention relates to the technical field of mutual inductor manufacturing equipment, in particular to a casting material conveying and pouring equipment for mutual inductor processing. Background Art

[0002] A transformer is an electrical device mainly used in power systems. It can convert high voltage or large current into low voltage or small current for measurement and protection.

[0003] In the field of transformer manufacturing, the casting process is one of the key steps in producing high-quality transformers. Traditional casting equipment may have some limitations in the casting process, such as the singleness of the casting pressure, which may cause uneven flow of the casting material in the mold, thus affecting the final quality and performance of the transformer. In addition, traditional equipment may not be able to effectively eliminate the bubbles generated during the casting process. These bubbles may form defects during the curing process, affecting the insulation performance and mechanical strength of the transformer. At the same time, there is also the problem that the existing casting equipment cannot match a variety of molds for casting. Summary of the invention

Three plug-in tubes are arranged at fixed intervals around the central axis of the outer tube, and the outer surface of the plug-in tube on the side away from the inner tube is fixedly connected to the bottom inner surface of the outer tube. The inner surface of the plug-in tube is elastically slidably plugged with a plug-in rod, and the plug-in rod is initially set to a fully extended state.

[0006] The inner surface of the plug rod is provided with a first spacer in close contact with the inner surface, and the outer surface of the plug rod is provided with a second spacer in close contact with the outer surface, the inner surface of the first spacer is fixedly connected to the bottom outer surface of the inner tube, and the outer surface of the second spacer is fixedly connected to the bottom inner surface of the outer tube, wherein the first spacer and the second spacer are mainly used to fill the gap between the inner and outer sides of the plug rod and the inner and outer tubes. When the mutual inductor needs to be cast, the device can be connected to the conveying pipeline through the top of the top cover, and the device is fixed by the connecting ring, and then the casting material is conveyed into the top cover. When the casting material enters the top cover, it enters the interior of the inner tube, and enters the cavity between the inner tube and the outer tube through the conveying trough on the inner tube, and is finally conveyed downward through the gap between the plug rod and the adjacent plug tube.

[0007] Preferably, a slide groove is provided at the bottom of the outer tube, and the slide groove is arranged in a ring shape. A driving ring is slidably connected to the inside of the slide groove, and a connecting block is fixedly connected to the inner surface of the driving ring. A connecting groove is penetrated through the inner surface of the bottom of the outer tube, and the connecting groove is closed by the driving ring. Three connecting grooves are provided at fixed intervals around the central axis of the outer tube, and the connecting groove also penetrates the second spacer. The connecting block is slidably arranged in the connecting groove, and the inner surface of the connecting block is fixedly connected to the end of the plug-in rod.

[0008] Preferably, a transmission rod is fixedly connected to the outer surface of the driving ring, and the transmission rod is arranged on a side of the connecting groove close to the outer surface of the outer tube. An end of the transmission rod away from the driving ring is fixedly connected to an adapter ring, and a connecting rod is fixedly connected to the bottom outer surface of the adapter ring. The connecting rod is arranged as a special-shaped rod, and the bottom of the connecting rod is arranged in a vertical shape.

[0009] Preferably, a matching strip is provided below the outer tube, and three matching strips are provided at fixed intervals around the central axis of the outer tube. Limiting grooves are provided through the upper and lower surfaces of the matching strip, and the bottom of the connecting rod is slidably inserted in the limiting groove. The bottom of the connecting rod and the matching strip are arranged perpendicular to each other, and the inner end of the matching strip is fixedly connected to an expansion plate.

[0010] Preferably, the expansion plate is arranged in an arc shape, and a rubber tube is fixedly connected to the inner surface of the expansion plate, and the rubber tube is made of flexible rubber material, and the rubber tube is arranged in a trumpet shape, and the top diameter of the rubber tube is larger than the bottom diameter, and a matching ring is fixedly connected to the top of the rubber tube, and the upper surface of the matching ring is rotatably connected to the bottom of the outer tube. When the pressure of the castable input into the inner tube through the top cover is different, the pressure of the castable between the inner tube and the outer tube is also different. When the input pressure gradually increases, the pressure of the castable through the plug rod and the plug tube will increase, thereby generating an extrusion force on the plug rod, so that the plug rod moves into the plug tube. As the plug rod moves, the drive ring will be driven to slide in the slide groove through the connecting block, thereby driving the transmission rod on the outer surface of the drive ring to rotate, and when the transmission rod starts to rotate with the drive ring, it will drive the linkage rod to start rotating through the adapter ring.

[0011] Preferably, the auxiliary mechanism comprises hinged plates, which are arranged in pairs as a group, and the hinged plates in the same group are symmetrically rotatably connected to the upper and lower surfaces of the matching strip away from the end of the expansion plate, and the inner surfaces of the hinged plates in the same group are fixedly connected with sliders.

[0012] Preferably, a guide rod is slidably connected to the interior of the slider, the guide rod is configured as a special-shaped rod, the bottom of the guide rod is horizontally arranged, and the bottom of the guide rod is also inclined relative to the expansion plate, and the top of the guide rod is fixedly connected to the bottom outer surface of the outer tube.

[0013] Preferably, the bottom surface of the mating ring is fixedly connected with a synchronous frame, the synchronous frame is arranged in a bent shape, the inner surface of the synchronous frame is fixedly connected to the top outer surface of the rubber tube, the bottom of the synchronous frame is fixedly sleeved on the middle outer surface of the connecting rod, the bottom lower surface of the synchronous frame is slidably connected with a limiting plate, the end of the limiting plate away from the synchronous frame is fixedly connected to the top outer surface of the expansion plate, the side surface of the expansion plate is symmetrically provided with a first stretching plate, the two ends of the first stretching plate are slidably inserted with a second stretching plate, the second stretching plate is fixedly connected through the wall of the expansion plate, when the mating strip drives the expansion plate to rotate, since the outer end of the mating strip is slidably connected to the guide rod through the slider, and the bottom of the guide rod is horizontally and obliquely arranged, when the connecting rod drives the mating strip to rotate, the mating strip will slide along the guide rod, and then the mating strip will also move outward during the rotation.

[0014] The present invention provides a casting material conveying and pouring device for mutual inductor processing, which has the following beneficial effects: 1. The castable conveying and pouring equipment for processing the transformer realizes the effect of pressurized shunting of the castable by setting a plug-in tube and a plug-in rod and cooperating with the inner tube. Pressurized shunting helps to reduce bubbles and gaps in the castable, thereby improving the insulation performance of the casted transformer and reducing the possibility of partial discharge. In addition, through pressurized shunting, the castable can better penetrate into the tiny gap between the winding and the core, thereby enhancing the mechanical strength of the overall structure and improving the durability and reliability of the transformer.

[0015] 2. The casting material conveying and pouring equipment processed by this mutual inductor, when the connecting rod rotates, the expansion plate will be driven to rotate through the matching strip at its bottom, and the inner surface of the expansion plate is connected to the bottom outer surface of the rubber tube, and the top of the rubber tube is connected with a matching ring, and the top of the matching ring is rotatably connected to the bottom of the outer tube. Therefore, when the expansion plate rotates with the rotation of the matching strip, the rubber tube and the matching strip will be driven to rotate with it, so that the rubber tube can be rotated according to the change of the pouring pressure during the pouring process, thereby ensuring the unblocking ability of the rubber tube and avoiding the problem of clogging and bonding of the rubber tube during the pouring process, thereby reducing the pouring quality.

[0016] 3. The casting material conveying and pouring equipment processed by the mutual inductor generates a tensile force on the rubber tube through the expansion plate, so that the diameter of the bottom of the rubber tube is automatically changed by increasing the pouring pressure, so as to achieve the effect of increasing the pouring tube diameter, and realize the automatic adaptation of the pouring tube diameter size according to the pouring pressure, so as to avoid the mismatch between the rubber tube and the mold size of different types of mutual inductors during the pouring process, resulting in the inability to effectively align the pouring port of the rubber tube and the mold, causing the pouring material to overflow onto the tray and the outer wall of the mold, which not only leads to the waste of casting material, but also increases the difficulty of cleaning. At the same time, when the expansion plate moves outward, it will also cause the second stretching plate to move outward synchronously, so that the diameter of the round tube composed of the second stretching plate and the first stretching plate is synchronously increased, and the contact surface between the first stretching plate and the bottom of the rubber tube assists in stretching the rubber tube, thereby greatly improving the working stability of the equipment, and at the same time, through the connection between the limit plate and the synchronous frame, there is a relatively rigid connection force between the expansion plate and the matching ring, so as to ensure that the rubber tube always follows the expansion plate to rotate in the same direction during the stretching process, and avoid the problem of torsion of the rubber tube.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] First embodiment: Figures 1 to 8 As shown, the present invention provides a technical solution: a casting material conveying and pouring equipment for mutual inductor processing, comprising an outer tube 1, a connecting ring 2 is fixedly installed on the middle outer surface of the outer tube 1, an inner tube 3 is arranged inside the outer tube 1, the bottom of the inner tube 3 is in a closed state, a feeding trough 4 is opened through the outer surface of the inner tube 3, and three feeding troughs 4 are opened at fixed intervals around the central axis of the inner tube 3, a top cover 5 is fixedly connected to the top of the inner tube 3, a fixing ring 6 is fixedly connected to the top outer surface of the inner tube 3, and the outer surface of the fixing ring 6 is fixedly connected to the top inner surface of the outer tube 1, and the fixing ring 6 is used to connect the outer tube 1 and the inner tube 3, and also includes: A pouring mechanism 7, which is fixedly mounted at the bottom of the outer tube 1 and is also disposed at the bottom of the inner tube 3, and is used to pour the mutual inductor; Auxiliary mechanism 8, the auxiliary mechanism 8 is fixedly mounted on the pouring mechanism 7, and the auxiliary mechanism 8 is used to cooperate with the pouring mechanism 7 to work; The pouring mechanism 7 includes a plug-in tube 71, which is arranged in an arc shape. The curvature of the plug-in tube 71 is arranged to be consistent with the curvature of the outer tube 1. Three plug-in tubes 71 are arranged at fixed intervals around the central axis of the outer tube 1. The outer surface of the plug-in tube 71 on the side away from the inner tube 3 is fixedly connected to the bottom inner surface of the outer tube 1. The inner surface of the plug-in tube 71 is elastically slidably plugged with a plug rod 72, and the plug rod 72 is initially set to a fully extended state.

[0021] The inner surface of the plug-in rod 72 is fitted with a first spacer 73, and the outer surface of the plug-in rod 72 is fitted with a second spacer 74. The inner surface of the first spacer 73 is fixedly fitted and connected to the bottom outer surface of the inner tube 3, and the outer surface of the second spacer 74 is fixedly fitted and connected to the bottom inner surface of the outer tube 1. The first spacer 73 and the second spacer 74 are mainly used to fill the gap between the inner and outer sides of the plug-in rod 72 and the inner tube 3 and the outer tube 1.

[0022] During operation, when the mutual inductor needs to be cast, the device can be connected to the conveying pipeline through the top of the top cover 5, and the device can be fixed by the connecting ring 2, and then the casting material is conveyed into the top cover 5. When the casting material enters the top cover 5, it enters the interior of the inner tube 3, and enters the cavity between the inner tube 3 and the outer tube 1 through the conveying trough 4 on the inner tube 3, and is finally conveyed downward through the gap between the plug-in rod 72 and the adjacent plug-in tube 71. By setting the plug-in tube 71 and the plug-in rod 72 and cooperating with the inner tube 3, the casting material can be pressurized and shunted. Pressurized shunting helps to reduce bubbles and gaps in the casting material, thereby improving the insulation performance of the casted mutual inductor and reducing the possibility of local discharge. In addition, through the pressurized shunting method, the casting material can better penetrate into the tiny gap between the winding and the core, thereby enhancing the mechanical strength of the overall structure and improving the durability and reliability of the mutual inductor.

[0023] Second embodiment: Figures 1 to 8 As shown, a slide groove 75 is provided at the bottom of the outer tube 1, and the slide groove 75 is arranged in an annular shape. A driving ring 76 is slidably connected inside the slide groove 75, and a connecting block 77 is fixedly connected to the inner surface of the driving ring 76. A connecting groove 78 is penetrated through the inner surface of the bottom of the outer tube 1, and the connecting groove 78 is closed by the driving ring 76. Three connecting grooves 78 are provided around the central axis of the outer tube 1 at fixed intervals. The connecting groove 78 is also penetrated through the second spacer 74. The connecting block 77 is slidably set in the connecting groove 78, and the inner surface of the connecting block 77 is fixedly connected to the end of the plug-in rod 72.

[0024] A transmission rod 79 is fixedly connected to the outer surface of the driving ring 76. The transmission rod 79 is arranged on the side of the connecting groove 78 close to the outer surface of the outer tube 1. An end of the transmission rod 79 away from the driving ring 76 is fixedly connected to an adapter ring 710. A connecting rod 711 is fixedly connected to the bottom outer surface of the connecting ring 710. The connecting rod 711 is arranged as a special-shaped rod, and the bottom of the connecting rod 711 is arranged in a vertical shape.

[0025] A matching strip 712 is provided below the outer tube 1. Three matching strips 712 are provided at fixed intervals around the central axis of the outer tube 1. Limiting grooves 713 are provided through the upper and lower surfaces of the matching strip 712. The bottom of the connecting rod 711 is slidably inserted into the limiting groove 713. The bottom of the connecting rod 711 and the matching strip 712 are arranged perpendicular to each other. The inner end of the matching strip 712 is fixedly connected to an expansion plate 714.

[0026] The expansion plate 714 is arranged in an arc shape, and a rubber tube 715 is fixedly connected to the inner surface of the expansion plate 714. The rubber tube 715 is made of a flexible rubber material. The rubber tube 715 is arranged in a trumpet shape. The top diameter of the rubber tube 715 is larger than the bottom diameter. A matching ring 716 is fixedly connected to the top of the rubber tube 715, and the upper surface of the matching ring 716 is rotatably connected to the bottom of the outer tube 1.

[0027] During operation, when the pressure of the castable input into the inner tube 3 through the top cover 5 is different, the pressure of the castable between the inner tube 3 and the outer tube 1 is also different. When the input pressure gradually increases, the pressure of the castable between the plug rod 72 and the plug tube 71 will increase, thereby generating an extrusion force on the plug rod 72, causing the plug rod 72 to move into the plug tube 71. As the plug rod 72 moves, the drive ring 76 will be driven to slide in the slide groove 75 through the connecting block 77, thereby driving the transmission rod 79 on the outer surface of the drive ring 76 to rotate. When the transmission rod 79 starts to rotate with the drive ring 76, it will drive the connecting rod 711 to start rotating through the adapter ring 710, and when the connecting rod 711 rotates When the expansion plate 714 moves, the mating strip 712 at the bottom thereof will drive the expansion plate 714 to rotate, and the inner surface of the expansion plate 714 is connected to the outer surface of the bottom of the rubber tube 715, and the top of the rubber tube 715 is connected to the mating ring 716, and the top of the mating ring 716 is rotatably connected to the bottom of the outer tube 1. Therefore, when the expansion plate 714 rotates with the rotation of the mating strip 712, the rubber tube 715 and the mating strip 712 will be driven to rotate with it, so that the rubber tube 715 can be rotated according to the change of the pouring pressure during the pouring process, thereby ensuring the unblocking ability of the rubber tube 715 and avoiding the problem of blockage and adhesion of the rubber tube 715 during the pouring process, thereby reducing the pouring quality.

[0028] The third embodiment: Figures 1 to 8As shown, the auxiliary mechanism 8 includes hinged plates 81, which are arranged in pairs as a group. The hinged plates 81 in the same group are symmetrically rotatably connected to the upper and lower surfaces of the matching strip 712 away from the end of the expansion plate 714, and the inner surface of the same group of hinged plates 81 is fixedly connected with a slider 82.

[0029] A guide rod 83 is slidably connected to the interior of the slider 82. The guide rod 83 is set as a special-shaped rod. The bottom of the guide rod 83 is set horizontally. The bottom of the guide rod 83 is also inclined relative to the expansion plate 714. The top of the guide rod 83 is fixedly connected to the bottom outer surface of the outer tube 1.

[0030] The bottom surface of the matching ring 716 is fixedly connected with the synchronization frame 84, and the synchronization frame 84 is set to a bent shape. The inner surface of the synchronization frame 84 is fixedly connected to the top outer surface of the rubber tube 715, and the bottom of the synchronization frame 84 is fixedly sleeved on the middle outer surface of the connecting rod 711. The bottom lower surface of the synchronization frame 84 is slidably connected with the limit plate 85, and the end of the limit plate 85 away from the synchronization frame 84 is fixedly connected to the top outer surface of the expansion plate 714. The side surface of the expansion plate 714 is symmetrically provided with a first stretching plate 86, and the second stretching plates 87 are slidably inserted inside the two ends of the first stretching plate 86, and the second stretching plate 87 is fixedly connected through the wall of the expansion plate 714.

[0031] During operation, when the matching strip 712 drives the expansion plate 714 to rotate, since the outer end of the matching strip 712 is slidably connected to the guide rod 83 through the slider 82, and the bottom of the guide rod 83 is horizontally inclined, the linkage rod 711 drives the matching strip 712 to rotate, which will cause the matching strip 712 to slide along the guide rod 83, and then the matching strip 712 will also move outward during the rotation process, and then a tensile force will be generated on the rubber tube 715 through the expansion plate 714, so that the diameter of the bottom of the rubber tube 715 is automatically changed by increasing the pouring pressure, so as to achieve the effect of increasing the pouring diameter, and realize automatic adaptation of the pouring diameter according to the pouring pressure, thereby avoiding the mismatch between the rubber tube 715 and the mold size of different types of mutual inductors during the pouring process, causing the rubber tube 715 and the mold to be inconsistent. The pouring port cannot be effectively aligned, causing the pouring material to overflow onto the tray and the outer wall of the mold, which not only leads to a waste of pouring material, but also increases the difficulty of cleaning. At the same time, when the expansion plate 714 moves outward, the second stretching plate 87 will also move synchronously outward, thereby causing the diameter of the circular tube formed by the second stretching plate 87 and the first stretching plate 86 to increase synchronously, and the contact surface between the first stretching plate 86 and the bottom of the rubber tube 715 assists in stretching the rubber tube 715, thereby greatly improving the working stability of the equipment. At the same time, through the connection between the limit plate 85 and the synchronous frame 84, a relatively rigid connection force exists between the expansion plate 714 and the matching ring 716, thereby ensuring that the rubber tube 715 always follows the expansion plate 714 to rotate in the same direction during the stretching process, thereby avoiding the problem of twisting of the rubber tube 715.
