Description

Technical Field

[0001] This invention relates to the field of transformer processing equipment technology, specifically a vacuum degassing and casting equipment for transformer processing. Background Technology

[0002] In the production and processing of dry-type transformers, epoxy resin vacuum casting is a core process to ensure the insulation performance of the coils. Vacuum degassing casting equipment for transformer processing is the key equipment for this process. It typically includes a vacuum tank, raw material storage tank, casting tank, and mold support platform. By completing the degassing treatment of the casting materials and the coil casting operation in a sealed vacuum environment, it effectively eliminates air bubble defects inside the insulation layer, ensuring the electrical insulation performance and operational stability of the finished transformer. With the continuous enrichment of transformer product models and insulation formulas, the same casting production line often needs to accommodate various specifications of transformer coil molds and different types of casting materials, placing higher demands on the equipment's material switching efficiency, mold positioning accuracy, and operational reliability.

[0003] In existing vacuum degassing casting equipment for transformer processing, the mold positioning and clamping process and the raw material silo conveying process operate independently. The clamping and positioning actions of the mold support structure cannot simultaneously achieve precise material discharge triggering and sealing verification of the corresponding silos. This not only results in cumbersome material changing operations and low overall production efficiency, but also easily leads to quality risks such as incorrect material casting and failure to promptly identify and address sealing failures. Furthermore, the mechanical locking reliability after mold clamping is insufficient, making it prone to positional shifts during vacuum evacuation and casting processes, directly affecting the casting quality of the transformer coils. Therefore, to address these shortcomings, there is an urgent need to develop a vacuum degassing casting equipment for transformer processing to overcome these deficiencies in current practical applications. Summary of the Invention

[0027] Both the telescopic channel 2 and the pulling slider 2 are also provided with staggered elastic plates, so that vibration is generated by the collision between the elastic plates during the mutual movement of the two.

[0028] As a further aspect of the present invention: the convex component includes an adjustable drive head, which is slidably mounted on one end of the support platform;

[0029] During the feeding process of the part to be cast, the adjustable drive head abuts against the corresponding pull slider and gradually pushes the pull slider to slide within the telescopic channel.

[0030] As a further aspect of the present invention: the convex component further includes:

[0031] A boss is fixedly installed on the other end of the support platform, and an adjustable slide is slidably installed on the boss.

[0032] A telescopic cylinder, which is fixedly mounted on the adjustable slide;

[0033] And two drive push blocks, which are fixedly installed on the two output ends of the telescopic cylinder respectively;

[0034] After the material to be cast is fed, the drive push block abuts against the corresponding pull slider two and gradually pushes the pull slider two to slide in the telescopic channel two.

[0035] As a further aspect of the present invention: the compartmentalized material discharge detection component includes:

[0036] A drive U-shaped frame is provided, one end of which is connected to the second transmission control component, and the other end of which is connected to the vacuum tank body via a torque rotating part.

[0037] A movable push head, which is located at the other end of the drive U-shaped frame;

[0038] The system includes a discharge detection unit, which is slidably connected to the vacuum tank and movably connected to the movable push head. The discharge detection unit is also connected to the first transmission control component and the raw material storage tank.

[0048] Compared with the prior art, the beneficial effects of the present invention are:

[0049] The system achieves linkage control between mold clamping and compartment material discharge. The first and second transmission control components are triggered synchronously during the positioning process of the support platform, which drives the compartment material discharge detection component to complete the directional material discharge and sealing verification of the corresponding raw material storage tank. This forms a double-layer error prevention mechanism, which effectively avoids the problem of incorrect material pouring. At the same time, it reduces the tank cleaning process when switching between different casting materials, and significantly improves production efficiency.

[0050] To improve the positioning accuracy and clamping stability of transformer coil molds, the positioning guide slot and clamping protrusion are used to guide the precise positioning of the support platform. Combined with the mechanical locking limit formed simultaneously during the clamping process, the displacement of the mold during vacuum pumping and casting is avoided, thus ensuring the positional accuracy of coil casting and the forming quality of the insulation layer.

[0051] The design integrates material discharge control and vacuum monitoring using a purely mechanical transmission structure, eliminating the need for numerous electronically controlled drive components inside the vacuum tank. This simplifies the design of the vacuum tank's sealing structure and reduces wiring complexity. Simultaneously, the vacuum level inside the raw material storage tank can be monitored in real time through the compartmentalized material discharge detection components, allowing for timely identification of sealing leakage risks and ensuring the vacuum degassing effect of the casting raw materials.

[0052] With excellent specification adaptability, the adjustable drive head, adjustable slide and telescopic cylinder on the support platform can be adjusted to flexibly change the trigger point, adapt to transformer coil molds of different sizes and specifications and compartment structures of different layouts, effectively expanding the scope of application of the equipment.

Detailed Implementation

[0064] 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.

[0065] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0066] Please see Figures 1-10 The present invention provides a vacuum degassing casting device for transformer processing, comprising a vacuum tank body, a vacuum tank base 1 at the bottom of the vacuum tank body, and further comprising:

[0067] A transformer coil mold casting platform 2 is fixedly installed on the vacuum tank base 1, and a support platform 28 is detachably provided on the transformer coil mold casting platform 2, on which the casting part is placed;

[0068] The transformer coil mold casting platform 2 is provided with a first transmission control component 4 and a second transmission control component 5 at both ends along the feeding direction, and each of the first transmission control component 4 and the second transmission control component 5 is provided with multiple branch drive control components.

[0069] According to the type of the part to be cast, the position of the corresponding protruding part on the support platform 28 is manually adjusted, and during the process of the support platform 28 contacting the transformer coil mold casting platform 2, the corresponding branch drive control component is driven synchronously, and a locking limit is formed between the transformer coil mold casting platform 2 and the support platform 28.

[0070] And a compartmentalized material discharge detection component, which is located inside the vacuum tank, with multiple compartmentalized material discharge detection components connected to multiple branch drive control components respectively;

[0071] The corresponding branch drive control unit drives the corresponding compartment material discharge detection component to operate. On the one hand, while the part to be cast enters the vacuum tank, the casting raw material is directionally discharged into the corresponding raw material storage tank 7. On the other hand, after a locking limit is formed between the transformer coil mold casting platform 2 and the support platform 28, the vacuum degree in the raw material storage tank 7 is monitored.

[0072] Please see Figures 1-10 It also includes: a casting placement plane 3, which is located in the middle of the transformer coil mold casting platform 2;

[0073] The casting placement plane 3 is provided with a plurality of positioning guide slots 10, which are parallel to the feeding direction of the part to be cast.

[0074] The mounting protrusions 30 are evenly distributed at the bottom end of the support platform 28 and engage with the positioning guide groove 10 when the casting part is fed.

[0075] And a casting tank 6, which is fixedly installed inside the vacuum tank and connected to multiple raw material storage tanks 7, for casting the transformer coil mold through a casting head provided at its bottom.

[0076] In this embodiment, the transformer coil mold to be cast is first fixed on the support platform 28. According to the mold specifications and the corresponding casting material type, the position of the protruding part on the support platform 28 is pre-adjusted. Then, the support platform 28 is pushed along the feeding direction to the casting placement plane 3 of the transformer coil mold casting platform 2. During the pushing process, the locking protrusion 30 at the bottom of the support platform 28 is embedded in the positioning guide groove 10 on the casting placement plane 3. The guiding constraint of the positioning guide groove 10 ensures that the movement path of the support platform 28 is accurate and without deviation, providing a basis for subsequent accurate triggering and positioning locking.

[0077] As the support platform 28 gradually comes into contact with the transformer coil mold casting platform 2, the protruding parts at the end of the support platform 28 sequentially trigger the corresponding branch drive control components on the first transmission control component 4 and the second transmission control component 5. After the support platform 28 is fully in place, the branch drive control components simultaneously complete the limiting action, so that a mechanical locking limit is formed between the transformer coil mold casting platform 2 and the support platform 28, to prevent the mold from shifting or deviating during subsequent vacuum pumping, raw material flow and casting process, and to ensure the positional accuracy of the coil casting and the forming quality of the insulation layer.

[0078] At the same time, the branch drive control component corresponding to the first transmission control component 4 synchronously drives the connected compartment discharge detection component to move, and directionally transports the corresponding type of casting material to the material storage tank 7 that matches the current mold. Through the compartmentalized multi-material storage tank 7, the independent storage and transportation of different types of casting materials can be realized, avoiding cross-contamination of different formula casting materials, greatly reducing the tank cleaning process during material changeover, and improving production efficiency.

[0079] After the raw material is conveyed, the branch drive control unit corresponding to the second transmission control unit 5 triggers the compartment discharge detection component to complete the sealing of the corresponding discharge channel, forming a feeding-sealing timing control. If the sealed raw material storage tank 7 does not match the feeding raw material storage tank 7, the corresponding silo cannot form an effective seal. When the vacuum tank is vacuumed later, the vacuum degree in the silo will not reach the set threshold. The vacuum detection unit can quickly determine the discharge error, forming a dual error prevention mechanism to avoid product scrap caused by incorrect material pouring.

[0080] After the discharge channel is sealed, the raw materials in the raw material storage tank 7 are stirred, vacuumed, and then poured. The detection units on the compartment discharge detection component can monitor the vacuum level in the corresponding raw material storage tank 7 in real time, identify sealing leakage problems in a timely manner, and ensure the vacuum degassing effect of the poured raw materials. After the raw materials are degassed, they are transported to the pouring tank 6 through pipelines. The pouring head at the bottom of the pouring tank 6 is used to pour the raw materials into the fixed transformer coil mold to complete the pouring operation, thereby realizing the vacuum degassing pouring process of the transformer coil.

[0081] In one embodiment of the present invention, please refer to Figures 1-10 The branch drive control unit on the first transmission control unit 4 includes:

[0082] Telescopic channel 11 is provided at the end of the transformer coil mold casting platform 2, and a pull slider 19 is slidably installed in the telescopic channel 11.

[0083] A return spring is also provided between the pull slider 19 and the telescopic channel 11;

[0084] The conductor tube 12 is fixedly installed on the transformer coil mold casting platform 2.

[0085] And steel wire 13, one end of which passes through the top of the conductor cylinder 12 and the transformer coil mold casting platform 2 and is fixedly connected to the pull slider 19, and the other end of the steel wire 13 is connected to the compartment discharge detection component;

[0086] A guide roller 9 is provided between the steel wire 13 and the compartment discharge detection component, and the guide roller 9 is rotatably connected to the vacuum tank.

[0087] The branch drive control unit on the second transmission control unit 5 includes:

[0088] Telescopic channel 2 14 is provided at the other end of the transformer coil mold casting platform 2, and a pull slider 20 is slidably installed in the telescopic channel 2 14.

[0089] A return spring is also provided between the second pull slider 20 and the second telescopic channel 14;

[0090] And steel wire 15, one end of which also passes through the top of the conductor cylinder 12 and the transformer coil mold casting platform 2 and is fixedly connected to the pull slider 20, and the other end of steel wire 15 is connected to the compartment discharge detection component.

[0091] Both the telescopic channel 11 and the pulling slider 19 are provided with staggered elastic sheets, so that vibration is generated by the collision between the elastic sheets during their mutual movement; thereby assisting in material discharge (increasing the discharge speed and avoiding adhesion).

[0092] Both the telescopic channel 214 and the pulling slider 20 are also provided with staggered elastic plates, so that vibration is generated by the collision between the elastic plates during their mutual movement.

[0093] In this embodiment, when the support platform 28 is pushed in along the feeding direction (the raw materials are added simultaneously during this process), the protruding part at the end of the support platform 28 first abuts against the end face of the pull slider 19 corresponding to the first transmission control component 4. As the support platform 28 continues to advance, the pull slider 19 slides inward along the inner cavity of the telescopic channel 11, while compressing the return spring inside the telescopic channel 11 to store energy. When the pull slider 19 moves, it simultaneously pulls the steel wire 13 to move along the inner cavity of the guide tube 12. After the guide roller 9 reverses the direction of the steel wire 13, it vertically transmits the pulling force to the compartment discharge detection component, thereby opening the discharge channel. The guide tube 12 constrains the movement path of the steel wire 13, preventing the steel wire 13 from bending, jamming, or coming out during the transmission process, ensuring the stability of the transmission process. The guide roller 9 converts the sliding friction of the steel wire 13 into rolling friction, greatly reducing transmission loss and extending the service life of the steel wire component.

[0094] Once the support platform 28 is fully in place (after the synchronous addition of raw materials), the convex part corresponding to the second transmission control component 5 abuts against the second pull slider 20, pushing the second pull slider 20 to slide inward along the second telescopic channel 14, simultaneously compressing the corresponding reset spring and pulling the second steel wire 15 to move along the guide tube 12, thereby driving the compartment discharge detection component to complete the sealing of the discharge channel; when the support platform 28 is removed after pouring, the elastic force of the reset spring pushes the first pull slider 19 and the second pull slider 20 to automatically reset along the channel, simultaneously releasing the tension of the first steel wire 13 and the second steel wire 15, so that the compartment discharge detection component returns to the initial standby state, without the need for additional reset drive components, simplifying the internal structural layout of the vacuum tank and reducing the difficulty of vacuum sealing design.

[0095] During the relative sliding of slider 19 along telescopic channel 11 and slider 20 along telescopic channel 24, the elastic plates on the channels and sliders are interleaved and collide and scrape each other, generating high-frequency micro-amplitude vibration. The vibration energy is transmitted to the inner wall of the discharge channel of the compartment discharge detection component through steel wire 13 and steel wire 25, which can help accelerate the flow rate of high-viscosity epoxy resin casting material, while avoiding the casting material from adhering to the inner wall of the channel and causing residue.

[0096] In one embodiment of the present invention, please refer to Figures 1-10 The convex component includes an adjustable drive head 29, which is slidably mounted on one end of the support platform 28.

[0097] During the feeding process of the part to be cast, the adjustable drive head 29 abuts against the corresponding pull slider 19 and gradually pushes the pull slider 19 to slide in the telescopic channel 11.

[0098] The convex component further includes:

[0099] A boss 31 is fixedly installed on the other end of the support platform 28, and an adjustable slide block 32 is slidably installed on the boss 31.

[0100] Telescopic cylinder 33, which is fixedly mounted on the adjustable slide block 32;

[0101] And drive push block 34, there are two drive push blocks 34, and the two drive push blocks 34 are respectively fixedly installed on the two output ends of the telescopic cylinder 33;

[0102] After the material to be cast is fed, the drive push block 34 abuts against the corresponding pull slider 20 and gradually pushes the pull slider 20 to slide in the telescopic channel 2 14.

[0103] In this embodiment, the adjustable drive head 29 can be slidably adjusted along the side wall of the feeding end of the support platform 28. According to the casting hopper number corresponding to the transformer coil mold to be cast, the adjustable drive head 29 is pre-adjusted to the position directly in front of the pull slider 19 of the corresponding first transmission control component 4. The adjustable drive head 29 can be fixed by bolt locking to ensure that when the support platform 28 is feeding and advancing, the adjustable drive head 29 can accurately abut and push the pull slider 19 at the corresponding position, opening only the discharge channel of the target hopper and avoiding the problem of mis-materials caused by accidentally triggering other branch drive control components.

[0104] An adjustable slide block 32 is provided on the boss 31 at the other end of the support platform 28. The adjustable slide block 32 can slide and lock along the length direction of the boss 31. The telescopic cylinder 33 is fixedly installed on the adjustable slide block 32. The bidirectional output ends of the cylinder 33 are respectively equipped with drive push blocks 34. The lateral distance between the two drive push blocks 34 can be adjusted by the telescopic movement of the telescopic cylinder 33. When the support platform 28 is in place, the telescopic cylinder 33 starts to drive the two drive push blocks 34 to extend outward and abut against the corresponding position of the pull slider 20, pushing the pull slider 20 to slide along the telescopic channel 2 14, triggering the blocking action of the discharge channel.

[0105] By coordinating the position adjustment of the adjustable slide block 32 with the spacing adjustment of the telescopic cylinder 33, the trigger position of the drive push block 34 can be flexibly adjusted to adapt to the branch structure of the second transmission control component 5 with different layout specifications, greatly improving the adaptability of the equipment to different types of transformer coil molds; at the same time, the timing design of the feeding mechanical triggering the first transmission control component 4 and the telescopic drive triggering the second transmission control component 5 after reaching the position ensures that there is a sufficient time difference between the opening and blocking action of the discharge channel, ensuring that the casting material can be completely discharged into the material storage tank 7, avoiding the problems of insufficient discharge and material residue caused by premature blocking.

[0106] In one embodiment of the present invention, please refer to Figures 1-10 The compartmentalized material discharge detection component includes:

[0107] A drive U-shaped frame 16 is provided, one end of which is connected to the second transmission control component 5, and the other end of which is connected to the vacuum tank body via a torque rotating part 17.

[0108] A movable push head 22 is located at the other end of the drive U-shaped frame 16;

[0109] The system includes a discharge detection unit, which is slidably connected to the vacuum tank and movably connected to the movable push head 22. The discharge detection unit is also connected to the first transmission control component 4 and the raw material storage tank 7.

[0110] The discharge detection unit includes:

[0111] A movable control cylinder 8 is slidably connected to the vacuum tank, and a feed pipe 23 is fixedly installed on the movable control cylinder 8, and a detection sensor is provided on the feed pipe 23.

[0112] A connecting hose 18 is provided, with its two ends connected to the movable control cylinder 8 and the raw material storage tank 7, respectively.

[0113] The movable push plate 21 is fixedly installed on the movable control cylinder 8, and the movable push plate 21 is also movably connected to the movable push head 22.

[0114] And a clutch component, which is located inside the movable control cylinder 8 and connected to the first transmission control component 4.

[0115] The clutch includes a sealing part 24, a reset sliding sleeve 25, a lifting rod 26, and a sealing ball 27;

[0116] The reset sleeve 25 is fixedly installed inside the movable control cylinder 8. The lifting rod 26 passes through the reset sleeve 25 and is slidably connected to the reset sleeve 25. The top end of the lifting rod 26 is also fixedly connected to the first transmission control component 4.

[0117] A sealing ball 27 is fixedly installed at the bottom end of the lifting rod 26, and the sealing part 24 is fixedly installed inside the movable control cylinder 8 and located between the connecting hose 18 and the feed pipe 23.

[0118] Under the pulling action of the first transmission control component 4, the lifting rod 26 pulls the sealing ball 27 upward and separates it from the sealing part 24, thereby realizing the conveying of raw materials; under the action of the movable push head 22 pushing the movable control cylinder 8 upward via the movable push plate 21, the sealing part 24 abuts against the sealing ball 27 again to form a seal.

[0119] In this embodiment, the second transmission control component 5 has a steel wire 15 fixedly connected to one end of the drive U-shaped frame 16. When the steel wire 15 is pulled downward, the drive U-shaped frame 16 swings downward around the rotation axis of the torque rotation part 17, causing the movable push head 22 at the other end of the drive U-shaped frame 16 to move upward synchronously. The spherical end of the movable push head 22 abuts against the lower surface of the movable push plate 21 and pushes the movable push plate 21 upward, thereby causing the movable control cylinder 8 to slide upward along the vertical guide structure inside the vacuum tank. The torque rotation part 17 has a built-in torque elastic element. When the tension of the steel wire 15 disappears, the torque elastic element causes the drive U-shaped frame 16 to swing in the opposite direction. The position releases the thrust on the movable control cylinder 8. The movable push head 22 is movably connected to the movable push plate 21. This can be done by having the movable push head 22 abut against the movable push plate 21 and being connected to the movable push plate 21 by a traction rope, or by setting two movable push plates 21 on the movable control cylinder 8 and having the movable push head 22 located between the two movable push plates 21. No specific limitation is made here. In addition, the sliding fit between the movable control cylinder 8 and the vacuum tank and the rotational fit between the torque rotating part 17 and the vacuum tank in this invention both use conventional motion fitting parts, such as slide rails and bearings, which will not be described in detail here.

[0120] The side wall of the movable control cylinder 8 is connected to the corresponding raw material storage tank 7 via a connecting hose 18. The feed pipe 23 at the top of the movable control cylinder 8 is sealed to the external casting raw material supply pipeline. The detection sensor integrated on the feed pipe 23 can monitor the feed flow rate and on / off status of the casting raw material, and can also detect the air pressure value inside the movable control cylinder 8 in real time. There is no need to separately lay vacuum sensors and can-penetrating lines in each raw material storage tank 7, which greatly simplifies the sealing structure and wiring difficulty of the vacuum tank.

[0121] The top of the lifting rod 26 is fixedly connected to the steel wire 13 of the first transmission control component 4. When the steel wire 13 is pulled downward, the lifting rod 26 slides upward along the inner hole of the reset sleeve 25, causing the sealing ball 27 fixed at its bottom end to move upward synchronously, so that the sealing ball 27 separates from the sealing end face of the sealing part 24, and the conveying channel between the feed pipe 23 and the connecting hose 18 is opened. The casting raw material can be stably conveyed to the raw material storage tank 7 through the feed pipe 23, the inner cavity of the movable control cylinder 8, and the connecting hose 18. The reset sleeve 25 (with a built-in reset spring that stores energy when the lifting rod 26 moves upward) forms a radial constraint on the lifting stroke of the lifting rod 26, ensuring that the movement path of the sealing ball 27 always coincides with the sealing center of the sealing part 24, avoiding sealing failure caused by offset.

[0122] After the raw material is conveyed, the movable control cylinder 8 moves upward as a whole under the push of the movable push head 22, so that the sealing part 24 inside the cylinder moves upward synchronously until the sealing end face of the sealing part 24 is tightly abutted against the fixed sealing ball 27, forming a reliable line seal. This structure achieves sealing by moving the cylinder and cooperating with the ball, without the need for additional independent valve drive components, and relies entirely on mechanical linkage to achieve channel opening and closing control.

[0123] After sealing is completed, the raw material storage tank 7, the connecting hose 18 and the movable control cylinder 8 form a closed cavity. The detection sensor on the feed pipe 23 can monitor the vacuum degree in the closed cavity in real time, identify abnormal problems such as sealing failure and leakage in a timely manner, and ensure the stability of the vacuum degassing process of the casting raw material. The connecting hose 18 is made of a flexible material that is resistant to vacuum and corrosion of casting materials. It can adapt to the lifting and lowering displacement of the movable control cylinder 8 to avoid stress cracking at the pipe connection and ensure the sealing performance of the vacuum cavity.
