Description

Technical Field

[0001] The present invention relates to the technical field of transformer casting, and particularly relates to a pouring material pipe positioning and distributing device for manufacturing transformers. Background Art

[0002] A transformer is a special type of transformer mainly used for measuring high voltages and large currents, converting high voltages and large currents into low voltages and small currents for the use of equipment such as measuring instruments and protection devices, while ensuring the safety of operators. Transformers are divided into current transformers and voltage transformers. Current transformers are used to measure large currents and convert large currents into small currents; voltage transformers are used to measure high voltages and convert high voltages into low voltages. Transformers have the advantages of high precision, strong reliability, small size, and light weight, and are widely used in fields such as power systems and industrial automation.

[0003] When manufacturing a transformer, it is necessary to insulate the coil and the iron core. Usually, the iron core and the coil are placed in a mold, and then an insulating material is injected into the mold to wrap the iron core and the coil, so as to improve the insulation performance and mechanical strength of the transformer. Commonly used pouring materials include epoxy resin, polyurethane, etc. After pouring, curing and post-treatment processes are also required to ensure the performance and reliability of the transformer. During pouring, it is necessary to position the mold and distribute the pouring material, so we have proposed a pouring material pipe positioning and distributing device for manufacturing transformers. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a pouring material pipe positioning and distributing device for manufacturing transformers, including:

[0005] A connecting pipe for connecting a pouring device, and a sleeve disposed outside the connecting pipe;

[0006] A distributing mechanism having a sealing structure for sealing and distributing the pouring material for molds of different diameters;

[0007] The outer side surface of the connecting pipe is slidably limited to the inner side surface of the sleeve, the inner side surface of the distributing mechanism is fixedly connected to the outer side surface of the sleeve, and the side of the distributing mechanism away from the sleeve is fixedly connected to the outer side surface of the connecting pipe;

[0008] Wherein, the distributing mechanism includes:

[0009] A sealing plate, which is arranged in a waveform for sealing molds of different diameters;

[0010] A driving component having an umbrella-shaped structure for driving the expansion of the sealing plate;

[0011] A fabric component, which has a spreading structure for driving raw materials to converge from the outermost side of the mold to the center;

[0012] The inner side of the sealing plate is fixedly connected to the outer side of the sleeve. The inner side of the driving component is fixedly connected to the outer side of the connecting pipe located outside the sleeve. The side of the driving component away from the connecting pipe is slidably connected to the outermost ring surface of the sealing plate. The fabric component is arranged on the side of the sealing plate away from the driving component, and the side of the fabric component close to the sealing plate extends into the connecting pipe. The surface of the fabric component located inside the connecting pipe is rotatably connected to the inner side of the connecting pipe. The pouring equipment is connected through the end of the connecting pipe away from the sealing plate. Press the connecting pipe, and the connecting pipe slides inside the sleeve, while driving the umbrella-shaped structure of the driving component to open, unfolding the sealing plate and covering it outside the circular mold to complete the sealing of the mold. The air inside the mold is pumped to vacuum from other positions of the mold. Under the vacuum negative pressure, the sealing plate is subjected to suction force and adheres better to the top of the mold to achieve better sealing. Subsequently, the pouring material is injected into the connecting pipe. The pouring material is spread to the inner side of the mold through the fabric component and gradually converges to the center during the filling process. Finally, it covers the iron core, leaving a certain pouring allowance to compensate for the shrinkage of the material after curing. During sealing, the sealing plate is flattened on the top of the mold, and the outermost side is covered on the outer side of the top of the mold, thereby positioning the pouring position. The sealing plate with a corrugated structure can change its circular area and can seal molds with different diameters, providing a sealing condition for pouring. The umbrella-shaped structure of the driving component can drive the sealing plate to unfold evenly, ensuring the uniform flattening of the sealing plate and ensuring that the sealing plate can be evenly covered on the outer side of the top of the mold to avoid gaps and affect the vacuum effect. The fabric component makes the raw materials converge from the inner side of the mold to the center and is pressed into the gap between the iron core and the coil from the outermost side under the vacuum pressure. Secondly, it covers the iron core and retains the processing allowance. As the pouring material is filled, the negative pressure inside the mold will gradually disappear. Filling the gap first can ensure the complete filling of the gap before the negative pressure disappears, avoiding gaps or bubbles in the product.

[0013] Further, a limiting groove is provided on the outer side of the connecting pipe. The limiting groove is trapezoidal, and several limiting grooves are evenly distributed along the circumferential direction of the connecting pipe. The inner sides of several limiting grooves are slidably connected with limiting plates, and the side of the limiting plate away from the axis of the connecting pipe is threadedly connected to the inner side of the sleeve. The end of the limiting plate away from the driving component is fixedly connected to the side of the fabric component close to the sealing plate. The connecting pipe slides inside the sleeve, driving the driving component to flatten the sealing plate. By providing the slidably adapted limiting groove and limiting plate, the sliding of the connecting pipe and the sleeve can be limited, avoiding the distortion of the sealing plate and affecting the sealing effect. The connecting pipe can be slid out of the sleeve, which is convenient for taking out and cleaning the connecting pipe. And under the tension of the elastic force of the sealing plate, the random sliding out of the connecting pipe can be avoided.

[0014] Furthermore, a protrusion is fixedly connected to the inner side surface of the sleeve, and the protrusion is arranged inside a plurality of limit grooves. There are a plurality of protrusions, and the plurality of protrusions are spirally distributed. A screw groove is provided on the side of the limit plate away from the axis of the connecting pipe, and the screw groove is arranged as a part of the thread. The limit plate and the sleeve are threadedly connected with the protrusion through the screw groove. The threadedly connected limit plate and sleeve can disassemble the limit plate, and then remove the fabric component fixed to the limit plate, which is convenient for cleaning.

[0015] Furthermore, the driving assembly comprises a fixing ring, the inner side surface of the fixing ring is fixedly connected to the outer side surface of the connecting tube, the outer side surface of the fixing ring is hingedly connected with a rod body, and a plurality of the rod bodies are evenly distributed along the circumference of the fixing ring, and the plurality of the rod bodies are distributed in an umbrella shape, and the ends of the plurality of the rod bodies away from the fixing ring are fixedly connected with a ring body, and the ring body penetrates the outermost circle of the sealing plate, and the surface of the ring body is slidably connected to the inner side surface of the sealing plate, the connecting tube moves downward, driving the fixing ring to descend, thereby driving the rod body hinged thereto to gradually become horizontal, driving the ring body to move, and finally driving the sealing plate to be flattened, and after flattening, the rod body presses against the sealing plate through the sealing plate Leaning against the top of the mold, the connecting tube continues to move, driving the rod body to deform at the abutting position, and then the sealing plate covers the outer side of the mold, and under the elastic force of the contraction of the sealing plate, the top of the mold can be sealed to ensure the vacuum effect, and under the vacuum suction, the top of the mold can be better sealed. As the castable is filled, the vacuum negative pressure disappears, and the removal of the sealing plate will not be affected by the negative pressure. While cooperating with the vacuum environment for better sealing, it is convenient to remove the product after curing, and it is convenient to realize continuous processing. The umbrella-shaped distribution of the rod body can evenly unfold the sealing plate to avoid wrinkles when the sealing plate is unfolded, and avoid affecting the sealing effect of the sealing plate.

[0016] Furthermore, the outer side surface of the sleeve is fixedly connected to a sliding rod, and there are several sliding rods distributed along the circumference of the sleeve. The surface of the sliding rod is slidably connected to a slider, and there are several sliders arranged along the axial direction of the sliding rod. The outer side surface of the slider is fixedly connected to a side of the sealing plate close to the rod body. The sealing plate is unfolded, driving the slider to slide on the surface of the sliding rod and produce a small axial deflection. The deflection of the slider drives the sliding rod to deform slightly. The slider is arranged to slide on the surface of the sliding rod, which can ensure the horizontal unfolding of the sleeve.

[0017] Further, the fabric component includes a fabric plate which is arranged in a conical shape. The fabric plate is disposed on the side of the sealing plate away from the feed end of the connecting pipe. The side of the limiting plate away from the feed end of the connecting pipe is fixedly connected to the surface of the fabric plate. The casting material enters from the feed end of the connecting pipe, passes through the connecting pipe, reaches the conical surface of the fabric plate, flows along the conical surface of the fabric plate, and finally enters the interior of the mold. The conical fabric plate can spread the raw material to a position away from the center of the mold, so that the raw material converges from the inner side of the mold to the center. Under the vacuum pressure, it is pressed into the gap between the iron core and the coil from the outside, and first fills the gap. It can complete the filling of the gap before the negative pressure inside the mold disappears, thereby ensuring the complete filling of the gap between the coil and the iron core and ensuring the insulation effect after curing.

[0018] Further, a rotating shaft is arranged inside the connecting pipe. One end of the rotating shaft close to the fabric plate penetrates the fabric plate, and the surface of the rotating shaft is rotatably connected to the inner side surface of the fabric plate. A stirring blade is fixedly connected to the surface of the rotating shaft inside the connecting pipe. The stirring blade is arranged in a spiral shape, and the outer side surface of the stirring blade is slidably connected to the inner side surface of the connecting pipe. Driving the rotation of the rotating shaft drives the rotation of the stirring blade to stir the injected casting material, causing the raw materials to be mixed, preventing some raw materials from continuously contacting the pipe wall, and preventing the heat of the casting material contacting the pipe wall from being transferred to the pipe wall to cause solidification. Moreover, when the spiral stirring blade rotates, it can prevent the viscous casting material from being blocked.

[0019] Further, a circular plate is fixedly connected to the side of the fabric plate away from the stirring blade. The surface of the circular plate is fixedly connected to the inner side surface of the fabric plate. A motor is arranged at the interval between the circular plate and the fabric plate. The motor is fixedly connected to the side of the circular plate close to the fabric plate. The side of the motor away from the circular plate is fixedly connected to one end of the rotating shaft inside the fabric plate, and the output end of the motor is fixedly connected to the rotating shaft. Starting the motor, the output end of the motor drives the rotation of the rotating shaft. By setting the circular plate and placing the motor at the interval between the circular plate and the fabric plate, the motor can be separated from the casting material to prevent the casting material from entering the motor and affecting its operation. At the same time, for the motor arranged at the interval, the heat generated during its operation is transferred to the fabric plate, and the heat is transferred to the raw material flowing on the surface of the fabric plate, which can play a certain heat preservation effect on the raw material.

[0020] Further, a connecting plate is arranged at the interval between the circular plate and the fabric plate. A plurality of connecting plates are arranged along the circumference of the circular plate. The connecting plate is fixedly connected to the side of the circular plate close to the motor, and the end of the connecting plate away from the circular plate is fixedly connected to the surface of the motor. The connecting plate is set to further fix the motor, preventing large vibrations generated during the operation of the motor and avoiding noise.

[0021] Furthermore, an isolation sleeve is rotatably connected to the surface of the rotating shaft. The end surface of the isolation sleeve is fixedly connected to the side of the cloth plate away from the circular plate. The inner side surface of the isolation sleeve is stepped, and the inner side surface of the isolation sleeve is rotationally limited to the surface of the rotating shaft. The isolation sleeve is provided to block the position where the rotating shaft penetrates the cloth plate, preventing the casting material from entering the gap, ensuring that the rotation of the rotating shaft is not affected. The inner side surface of the isolation sleeve is stepped, and the stepped inner side surface can form multiple seals, maximizing the prevention of the casting material from entering the gap between the isolation sleeve and the rotating shaft, and further maintaining the rotation of the rotating shaft.

[0022] The beneficial effects of the present invention are as follows:

[0023] By providing a cloth mechanism, the sealing plate is flattened on the top of the mold, and the outermost side is wrapped around the outer side surface of the top of the mold, thereby positioning the pouring position. The sealing plate with a corrugated structure can change its circular area and can seal molds with different diameters, providing a sealing condition for pouring. The umbrella-shaped structure of the driving component can drive the sealing plate to unfold evenly, ensuring the uniform flattening of the sealing plate, ensuring that the sealing plate can be evenly wrapped around the outer side surface of the top of the mold, avoiding the generation of gaps and affecting the vacuum effect. The cloth component makes the raw materials converge from the inner side surface of the mold to the center and is pressed into the gap between the iron core and the coil from the outermost side under the vacuum pressure. Secondly, the iron core is covered with a machining allowance. As the casting material is filled, the negative pressure inside the mold will gradually disappear. Filling the gap first can ensure the complete filling of the gap before the negative pressure is eliminated, avoiding the generation of gaps or bubbles in the product.

[0024] By providing a limiting groove, the limiting groove and the limiting plate that are slidably adapted can limit the sliding of the connecting pipe and the sleeve, preventing the sealing plate from being distorted and affecting the sealing effect. The connecting pipe can slide out of the sleeve, which is convenient for taking out the connecting pipe for cleaning. And under the tension of the elastic force of the sealing plate, it can prevent the connecting pipe from sliding out randomly. The limiting plate and the sleeve that are threadedly connected can disassemble the limiting plate, and then remove the cloth component fixed to the limiting plate, facilitating its cleaning.

[0025] By providing a driving component, it drives the sealing plate to wrap around the outer side surface of the mold, and under the elastic force of the contraction of the sealing plate, it can seal the top of the mold, ensuring the vacuum effect. And under the vacuum suction force, it can better seal the top of the mold. As the casting material is filled, the vacuum negative pressure disappears, and the removal of the sealing plate will not be affected by the negative pressure. While cooperating with the vacuum environment for better sealing, it is convenient for the removal of the product after curing, facilitating continuous processing. The umbrella-shaped distributed rod bodies can evenly unfold the sealing plate, avoiding the generation of wrinkles when the sealing plate unfolds and affecting the sealing effect of the sealing plate.

[0026] Through the provision of a fabric component and a conical fabric plate, the present invention can spread raw materials to positions away from the center of the mold, causing the raw materials to converge from the inner side of the mold towards the center. Under vacuum pressure, the raw materials are pressed into the gap between the iron core and the coil from the outside, and the gap is filled first. It is possible to complete the filling of the gap before the negative pressure inside the mold disappears, thereby ensuring the complete filling of the gap between the coil and the iron core and ensuring the insulation effect after curing.

[0027] Through the provision of stirring blades, the present invention stirs the injected casting material to mix the raw materials, avoiding continuous contact of some raw materials with the pipe wall, preventing the heat transfer of the casting material in contact with the pipe wall to the pipe wall and causing solidification. At the same time, when the spiral stirring blades rotate, they can prevent the viscous casting material from getting blocked. Additionally, the heat generated by the operation of the motor is transferred to the fabric plate and then to the raw materials flowing on the surface of the fabric plate, which can provide a certain heat preservation effect on the raw materials.

[0028] Through the provision of an isolation sleeve, the present invention shields the position where the rotating shaft penetrates the fabric plate, preventing the casting material from entering the gap, ensuring that the rotation of the rotating shaft is not affected. The inner side of the isolation sleeve is stepped, and the stepped inner side can form multiple seals, which can maximize the prevention of the casting material from entering the gap between the isolation sleeve and the rotating shaft, further maintaining the rotation of the rotating shaft.

[0056] The surface of the rotating shaft 332 is rotatably connected with an isolation sleeve 337, the end surface of the isolation sleeve 337 is fixedly connected to the side of the cloth plate 331 away from the circular plate 334, and the inner side surface of the isolation sleeve 337 is arranged in a stepped shape, the inner side surface of the isolation sleeve 337 and the surface of the rotating shaft 332 are rotationally limited, and the isolation sleeve 337 is arranged to block the position where the rotating shaft 332 passes through the cloth plate 331 to prevent the casting material from entering its gap, thereby ensuring that the rotation of the rotating shaft 332 is not affected, and the inner side surface of the isolation sleeve 337 is stepped, and the stepped inner side surface can form multiple seals, which can prevent the casting material from entering the gap between the isolation sleeve 337 and the rotating shaft 332 to the greatest extent, thereby further maintaining the rotation of the rotating shaft 332.

[0057] When in use, the connecting tube 2 is pressed, and the connecting tube 2 slides inside the sleeve 1, driving the fixing ring 321 to descend, thereby driving the rod body 322 hinged therewith to gradually become horizontal, driving the ring body 323 to move, and finally driving the sealing plate 31 to flatten, and the sealing plate 31 to unfold, driving the slider 325 to slide on the surface of the sliding rod 324, and causing a small axial deflection, the slider 325 deflects, driving the sliding rod 324 to deform slightly, and after flattening, the rod body 322 abuts against the top of the mold through the sealing plate 31, and the connecting tube 2 continues to move, driving the rod body 322 to deform at the abutting position, and then the sealing plate 31 covers the outer side surface of the mold, and Under the elastic force of the contraction of the sealing plate 31, the top of the mold can be sealed, and the mold can be evacuated from other positions of the mold. Under the vacuum negative pressure, the sealing plate 31 is sucked and better adheres to the top of the mold to achieve better sealing. Then, the casting material is injected from the inside of the connecting pipe 2. The casting material passes through the connecting pipe 2 and reaches the conical surface of the distribution plate 331, flows along the conical surface of the distribution plate 331, and finally enters the mold. While pouring, the motor 335 is started, and the output end of the motor 335 drives the rotating shaft 332 to rotate, drives the stirring blade 333 to rotate, stirs the injected casting material, and finally completes the pouring.
