Description

Technical Field

[0001] This invention relates to the field of core processing technology, specifically to a tensioning platform and method for processing transformer cores. Background Technology

[0002] The transformer core is the core component of a transformer that transmits magnetic flux and forms the main magnetic circuit. Its performance directly affects key indicators such as transformer efficiency, no-load loss, noise, and temperature rise. The assembly of laminated cores is the most basic and core assembly form of transformer cores. The core of this assembly is to achieve a closed magnetic circuit by stacking silicon steel sheets layer by layer, staggering the joints, and pressing them evenly.

[0003] In traditional lamination processes, silicon steel sheets rely on manual visual alignment or simple stop block positioning, which is prone to interlayer misalignment due to vibration and operational errors, affecting the continuity of the core magnetic circuit and no-load losses. Furthermore, existing positioning stops are mostly specialized tooling, requiring the replacement of the entire tooling set when changing product models, resulting in insufficient versatility.

The bottom block is inserted into the positioning holes and the square magnetic block. The bottom block is made of iron. The tensioning component includes a backing plate made of rubber. The backing plate slides with the guide rod.

[0005] Furthermore, the guide component also includes a rotating block one, which is rotatably connected to the top of the base block. A cross groove is formed on the top of the rotating block one, and a sliding sleeve is slidably connected within the cross groove. A pressure rod is slidably connected within the sliding sleeve, and a spring is fitted onto the pressure rod. The two ends of the spring are fixedly connected to the top of the sliding sleeve and the top of the pressure rod, respectively. A rotating block two is provided on the top of the rotating block one, and a cross groove two is formed on the rotating block two. A sliding sleeve is slidably connected to the cross groove two. Multiple limiting blocks are fixedly connected to the top of the rotating block two. The top surface of the second component is fixedly connected to a sleeve. The guide rod is rotatably connected to the top surface of the sleeve. A through groove is opened on the guide rod. A rotating plate is rotatably connected in the through groove. Two torsion springs are symmetrically fixedly connected on the rotating plate. The end of the torsion spring away from the rotating plate is fixedly connected to the groove wall of the through groove. A telescopic tube is fixedly connected to the bottom end of the guide rod. The telescopic end of the telescopic tube faces downward. A pressure plate is fixedly connected to the telescopic end of the telescopic tube. A second spring is installed inside the telescopic tube. The two ends of the second spring are fixedly connected to the guide rod and the pressure plate, respectively. A lifting plate is fixedly connected to the telescopic tube.

[0006] Furthermore, the tensioning component also includes multiple positioning slots arranged in a vertical straight array on the guide rod. A slide plate is slidably connected to the guide rod, and a slot is provided on the slide plate. An insert rod is slidably connected in the slot, and the insert rod is inserted into the positioning slot. A spring three is sleeved on the insert rod, and the two ends of the spring three are fixedly connected to the slide plate and the insert rod, respectively. Two slide rods are symmetrically slidably connected to the slide plate, and a stop plate is fixedly connected to the bottom ends of the two slide rods. A spring four is sleeved on each of the two slide rods, and the two ends of the spring four are fixedly connected to the bottom surface of the slide plate and the top surface of the stop plate, respectively.

[0007] Furthermore, the lower surface of the second rotating block abuts against the upper surface of the first rotating block, and the top and bottom surfaces of the pressure rod, the top surface of the limiting block, and the bottom surface of the pressure plate are all made of anti-slip surfaces with a frosted finish. The bottom surface of the pressure rod is pressed against the top surface of the bottom block.

[0008] Furthermore, the pressure plate and the top surface of the limiting block and the pressure rod are pressed together, and the rotating plate and the lifting plate are pressed together.

[0009] A tensioning method for processing transformer cores includes the following steps: Step 1: Place a single silicon steel sheet on the top surface of the base, select a guide component, insert the bottom block into the positioning hole at the edge of the silicon steel sheet, and at the same time, make the bottom block and the square magnetic block fit together. Use the magnetic attraction of the square magnetic block and the square limiting structure to fix the bottom block and prevent it from rotating.

[0010] Further, in step two: Press down on one end of the rotating plate extending through the slot, causing the rotating plate to move the lifting plate, telescopic tube, and pressure plate upward. Spring two is compressed, and spring one elastically extends to push the pressure rod upward, releasing the pressure rod from contact with the bottom block. Push and rotate the guide rod, and with the help of the movement of the sliding sleeve in cross groove one and cross groove two, adjust the guide rod to contact and fit with the silicon steel sheet. Rotate the rotating plate to the side away from the processing path and then release it. Utilize the restoring action of the torsion spring and spring two to make the pressure plate press the pressure rod and the limiting block. Lock the guide rod through the friction of the anti-slip surface. Install multiple guide components in the positioning holes around and in the gaps of the silicon steel sheet, so that multiple guide rods clamp the silicon steel sheet and provide guidance.

[0011] Further, in step three: through the area between multiple guide rods, slide the subsequent silicon steel sheets from top to bottom along the guide rods to complete the stacking and splicing of silicon steel sheets to form an iron core. Install tensioning components on each guide rod, pull the insert rod to disengage it from the slot, slide the slide plate and the abutment plate from the top of the guide rod and move it down until the rubber abutment plate touches the top surface of the iron core. Push the slide plate down to compress the spring four to the required elastic force, release the insert rod, and use the spring three to reset so that the insert rod is inserted into the positioning groove and slot, fix the deformation state of the slide plate and the spring four, and apply a uniform tension force around the iron core. Step 4: Pull the insert rod to disengage from the positioning groove and slot, remove the slide plate and the stop plate from the guide rod, release the tension, press the rotating plate to adjust the guide rod to be coaxial with the bottom block, release its contact with the iron core, pull the guide rod upward to make the bottom block disengage from the positioning hole and the square magnetic block, after disassembling all the guide components, remove the stacked iron core from the base.

[0012] Compared with the prior art, the beneficial effects of the present invention are: By operating the platform components, a uniform and adjustable tension force is applied to the silicon steel sheet stack, eliminating gaps between the silicon steel sheets and preventing loosening or deformation during subsequent assembly and operation. At the same time, it ensures consistent alignment of the silicon steel sheet stack, improves the overall magnetic permeability of the core, and reduces the no-load loss of the transformer.

[0013] Through the operation of the platform components, a guide rod was designed to precisely limit the inner and outer openings of the silicon steel sheet at multiple positions, providing guidance for subsequent lamination and avoiding interlayer misalignment. At the same time, through modular design, the guide rod can move and limit flexibly, thereby adapting to the processing requirements of transformer cores of different models and sizes.

[0016] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0017] Example 1: Reference Figures 1 to 9 As shown, a tensioning platform for processing transformer cores includes a platform assembly. The platform assembly is used to assist in the stacking and splicing of silicon steel sheets 11. The platform assembly includes a bottom component, multiple guide components, and multiple tensioning components.

[0018] The bottom component is used to support the silicon steel sheet 11.

[0019] The bottom component includes a base 21, a silicon steel sheet 11 is placed on top of the base 21, and a plurality of positioning holes 22 are evenly opened on the top surface of the base 21. A square magnetic block 23 is fixedly connected to the bottom of the hole wall of each positioning hole 22.

[0020] The guide component is used to provide guidance during the lamination and splicing process of silicon steel sheets 11.

[0021] The guide component includes a base block 24, which is inserted into a positioning hole 22 and a square magnetic block 23. A rotating block 25 is rotatably connected to the top of the base block 24. A cross groove 26 is formed on the top of the rotating block 25. A sliding sleeve 27 is slidably connected within the cross groove 26, and a pressure rod 28 is slidably connected within the sliding sleeve 27. A spring 29 is fitted onto the pressure rod 28, and both ends of the spring 29 are fixedly connected to the top of the sliding sleeve 27 and the top of the pressure rod 28, respectively. A rotating block 210 is provided on the top of the rotating block 25. A cross groove 211 is formed on the rotating block 210, and the sliding sleeve 27 is slidably connected to the cross groove 211. Multiple limiting blocks 212 are fixedly connected to the top of the rotating block 210. A sleeve 213 is fixedly connected to the top surface of 210.

A rotating plate 216 is rotatably connected in the through groove 215. Two torsion springs 217 are symmetrically fixedly connected to the rotating plate 216. The end of the torsion spring 217 away from the rotating plate 216 is fixedly connected to the groove wall of the through groove 215. A telescopic tube 218 is fixedly connected to the bottom end of the guide rod 214. The telescopic end of the telescopic tube 218 faces downward.

The two ends of the second spring 220 are fixedly connected to the guide rod 214 and the pressure plate 219 respectively. A lifting plate 221 is fixedly connected to the telescopic tube 218.

[0022] The base block 24 is made of iron and its function is to magnetically attract the square magnet 23, thereby enhancing the stability of the base block 24 when it is inserted into the positioning hole 22. The square shape of the square magnet 23 is to ensure that the base block 24 cannot rotate when it is inserted into the positioning hole 22.

[0023] Among them, the lower surface of rotating block 210 abuts against the upper surface of rotating block 25.

[0024] Among them, the top and bottom surfaces of the pressure rod 28, the top surface of the limiting block 212, and the bottom surface of the pressure plate 219 are all made of anti-slip surfaces with a frosted finish. The bottom surface of the pressure rod 28 is pressed and fitted with the top surface of the bottom block 24, and the pressure plate 219 is pressed and fitted with the top surface of the limiting block 212 and the pressure rod 28.

[0025] Among them, the rotating plate 216 and the lifting plate 221 are in a pressing fit.

[0026] It should be noted that when the bottom block 24 is inserted into the positioning hole 22, the top surface of the first rotating block 25 is flush with the top surface of the base 21. That is, the lower surface of the second rotating block 210 is in contact with the top surface of the base 21.

[0027] The tensioning component is used to apply a uniform and adjustable tension force to the silicon steel sheet 11-layer stack.

[0028] The tensioning component includes multiple positioning grooves 31 arranged in a vertical straight array on the guide rod 214. A slide plate 32 is slidably connected to the guide rod 214. A slot 33 is provided on the slide plate 32. An insert rod 34 is slidably connected in the slot 33. The insert rod 34 is inserted into the positioning groove 31. A spring 35 is sleeved on the insert rod 34. The two ends of the spring 35 are fixedly connected to the slide plate 32 and the insert rod 34, respectively. Two slide rods 36 are symmetrically slidably connected on the slide plate 32. The bottom ends of the two slide rods 36 are fixedly connected to a stop plate 37. A spring 48 is sleeved on each of the two slide rods 36. The two ends of the spring 48 are fixedly connected to the bottom surface of the slide plate 32 and the top surface of the stop plate 37, respectively.

[0029] Among them, the abutment plate 37 and the guide rod 214 are in sliding fit.

[0030] Among them, the abutment 37 is made of rubber.

[0031] In the initial state of the platform component, before the silicon steel sheets 11 have been stacked and spliced, the structural states within the platform component are as follows: The base block 24 is not inserted into the positioning hole 22. The sliding sleeve 27 is simultaneously located in the center of the cross groove 26 and the cross groove 211. The base block 24 and the guide rod 214 are vertically coaxial at this time. The bottom end of the spring 29 is in contact with the upper surface of the base block 24. The bottom surface of the pressure plate 219 is in contact with the limiting block 212 and the top end of the spring 29. The spring 29 is elastically compressed. The spring 220 does not produce elastic deformation. The telescopic shaft of the telescopic tube 218 is fully extended. The torsion spring 217 does not produce elastic deformation. The rotating plate 216 is in contact with the lifting plate 221. The end of the rotating plate 216 that extends into the sleeve 213 is tilted downwards. The sliding plate 32 does not slide on the guide rod 214. The insertion rod 34 is inserted into the slot 33. The spring 35 and the spring 4 do not produce elastic deformation.

[0032] When the platform components are running, specifically when the stacking and splicing of silicon steel sheets 11 is required, the specific details are as follows: The user places a single silicon steel sheet 11 on the top surface of the base 21. Then, the user selects a single guide component and inserts the bottom block 24 into a positioning hole 22 located near the edge of the silicon steel sheet 11. At the same time, the bottom block 24 is inserted into the square magnet 23. The bottom block 24 is magnetically attracted by the square magnet 23 and is limited by the square magnet 23, so that the bottom block 24 cannot be rotated in the positioning hole 22.

[0033] After completion, the user presses down continuously on one end of the rotating plate 216 located outside the through groove 215, causing the end of the rotating plate 216 located inside the sleeve 213 to rotate upward, while causing the torsion spring 217 to undergo elastic deformation. As the rotating plate 216 rotates, it pushes the lifting plate 221 upward, causing the lifting plate 221 to drive the telescopic end of the telescopic tube 218 to move upward. At this time, the telescopic end of the telescopic tube 218 drives the pressure plate 219 to move upward, while the second spring 220 is elastically compressed.

[0034] At this point, the pressure plate 219 no longer abuts against the pressing limit block 212 and the pressure rod 28. Under the elastic extension of the spring 29, the spring 29 pushes the pressure rod 28 upward, causing the pressure rod 28 to slide upward within the sliding sleeve 27. Consequently, the bottom end of the pressure rod 28 no longer abuts against the bottom block 24. At this time, the user can push the guide rod 214 towards the silicon steel sheet 11, causing the guide rod 214 to abut against and adhere to the silicon steel sheet 11. During this process, the sliding of the sliding sleeve 27 within the cross groove 26 and the cross groove 211 causes the relative positions of the rotating block 25 and the rotating block 210 to change. That is, the guide rod 214 is displaced from the top of the bottom block 24, thereby allowing the guide rod 214 to obtain a radial movement range of the straight length within the cross groove 211 and the cross groove 26. Simultaneously, by rotating the rotating block 25 and the sleeve 213, the guide rod 214 obtains a circumferential movement range around the sliding sleeve 27 as the axis of rotation. The position of the guide rod 214 can be adjusted so that the guide rod 214 can move within the surrounding positioning holes 22 at the current insertion position.

[0035] At this point, the user places the guide rod 214 against the silicon steel sheet 11 and rotates the guide rod 214, turning the end of the rotating plate 216 that protrudes from the through slot 215 to the side away from the silicon steel sheet 11, so that the end of the rotating plate 216 that protrudes from the through slot 215 is not located on the stacking and splicing processing path of the silicon steel sheet 11. After completion, the user no longer presses the end of the rotating plate 216 that protrudes from the sleeve 213, and then, under the elastic reset action of the torsion spring 217, the rotating plate 216 returns to its tilted state. At the same time, under the elastic extension action of the second spring 220, the second spring 220 pushes the telescopic end of the telescopic tube 218 downward to extend, and the telescopic end of the telescopic tube 218 drives the pressure plate 219 to move downward. At this time, the pressure plate 219 pushes the pressure rod 28 downward to move synchronously, so that the pressure rod 28 slides downward in the sliding sleeve 27 until the bottom end of the pressure rod 28 abuts against the pressing block 24. At the same time, the bottom surface of the pressure plate 219 abuts against the top of the pressing limit block 212. At this time, the pressure plate 219 is pressed against the limiting block 212 and the pressure rod 28, and the pressure rod 28 is pressed against the bottom block 24. Since the top and bottom surfaces of the pressure rod 28, the top surface of the limiting block 212 and the bottom surface of the pressure plate 219 are all made into anti-slip surfaces with a frosted finish, the guide rod 214 and the rotating block 210 are locked on the bottom block 24 by friction and cannot move or rotate. At this time, the installation of a single guide component is completed.

[0036] After completion, the user can select multiple guide components and insert them into the positioning holes 22 at the corresponding edges of the silicon steel sheet 11, ensuring that each guide rod 214 is in contact with and adheres to the silicon steel sheet 11, so that the silicon steel sheet 11 is surrounded by guide rods 214, with multiple guide rods 214 clamping the silicon steel sheet 11 inside. At this time, the user can perform stacking and splicing processing on the silicon steel sheet 11 on the base 21 through the area between the multiple guide rods 214. During this process, the multiple guide rods 214 located around the silicon steel sheet 11 provide guidance for the subsequent stacking of the silicon steel sheet 11. The user only needs to align the silicon steel sheet 11 with each guide rod 214 and slide the silicon steel sheet 11 from top to bottom to achieve the stacking and splicing processing.

[0037] After the stacking and splicing process is completed, multiple silicon steel sheets 11 are stacked and spliced ​​to form an iron core. The user installs a tensioning component on each guide rod 214, as follows: The user pulls the insertion rod 34 away from the slide plate 32, causing the insertion rod 34 to disengage from the slot 33. At the same time, the spring 35 is elastically stretched. After completion, the user keeps pulling the insertion rod 34 and inserts the abutment plate 37 and the slide plate 32 downward from the top of the guide rod 214. The abutment plate 37 and the positioning hole 22 move vertically downward along the guide rod 214 until the bottom surface of the abutment plate 37 touches the top surface of the stacked iron core. At this time, the abutment plate 37 cannot move further downward because it touches the silicon steel sheet 11. The user pushes the slide plate 32 downward to move. At this time, as the slide plate 32 moves. Spring 38 is correspondingly elastically compressed, and the elastic deformation of spring 38 increases as the slide plate 32 moves downward. When spring 38 deforms to the elastic force required by the user, the user stops pulling the insertion rod 34. At this time, under the elastic restoring action of spring 35, the insertion rod 34 is pulled and inserted into the positioning groove 31 at the current position, and simultaneously inserted into the slot 33. Thus, the insertion rod 34 limits the slide plate 32 on the guide rod 214 and fixes the elastic deformation state of spring 38 at this time. This allows pressure to be applied to multiple parts around the iron core.

[0038] When the iron core needs to be removed, the user pulls out the insertion rod 34 and slides the abutment plate 37 and the sliding plate 32 upward from the guide rod 214 until they are disengaged from the guide rod 214, thus disassembling the tensioning component. At the same time, the user presses the end of the rotating plate 216 located outside the sleeve 213 to move the guide rod 214 to a position coaxial with the bottom block 24. At this time, the guide rod 214 no longer contacts the silicon steel sheet 11. Then, the user pulls the guide rod 214 upward, causing the bottom block 24 to disengage from the positioning hole 22. The bottom block 24 is no longer magnetically attracted to the square magnet 23. At this time, the disassembly of the guide component is completed, and the user can remove the iron core from the base 21.

[0039] In summary, the following beneficial effects can be achieved through the operation of platform components: By operating the platform components, a uniform and adjustable tension force is applied to the silicon steel sheet 11 stack, eliminating the gaps between the silicon steel sheet 11 stacks and preventing loosening and deformation during subsequent assembly and operation; at the same time, it ensures that the silicon steel sheet 11 stacks are aligned in a consistent manner, improves the overall magnetic permeability of the core, and reduces the no-load loss of the transformer.

[0040] Through the operation of the platform components, the guide rod 214 was designed to precisely limit the inner and outer openings of the silicon steel sheet 11 at multiple positions, providing guidance for subsequent stacking and avoiding interlayer misalignment. At the same time, through modular design, the guide rod 214 can move and limit flexibly, thereby adapting to the processing requirements of transformer cores of different models and sizes.

[0041] Example 2: A tensioning method for processing transformer cores includes the following steps: Step 1: Place the single silicon steel sheet 11 on the top surface of the base 21, select a guide component, insert the bottom block 24 into the positioning hole 22 at the edge of the silicon steel sheet 11, and at the same time make the bottom block 24 and the square magnetic block 23 fit together. Utilize the magnetic attraction of the square magnetic block 23 and the square limiting structure to fix the bottom block 24 and prevent it from rotating.

[0042] Step 2: Press down on one end of the rotating plate 216 extending from the through slot 215, causing the rotating plate 216 to move the lifting plate 221, telescopic tube 218, and pressure plate 219 upwards. Spring 220 is compressed, and spring 29 extends elastically to push the pressure rod 28 upwards, releasing the pressure rod 28 from contact with the bottom block 24. Push and rotate the guide rod 214, and adjust the guide rod 214 to contact and fit with the silicon steel sheet 11 by the movement of the sliding sleeve 27 in the cross slot 1 26 and cross slot 2 211. Rotate the rotating plate 216 to the side away from the processing path and then release it. Utilize the restoring action of the torsion spring 217 and spring 220 to make the pressure plate 219 press the pressure rod 28 and the limiting block 212. Lock the guide rod 214 by the friction of the anti-slip surface. Install multiple guide components in the positioning holes 22 around and in the gaps of the silicon steel sheet 11, so that multiple guide rods 214 clamp the silicon steel sheet 11 and provide guidance.

[0043] Step 3: Through the area between multiple guide rods 214, slide the subsequent silicon steel sheet 11 from top to bottom along the guide rods 214 to complete the stacking and splicing of the silicon steel sheet 11 to form an iron core. Install tensioning components on each guide rod 214, pull the insert rod 34 to disengage it from the slot 33, slide the slide plate 32 and the abutment plate 37 from the top of the guide rod 214 and move them down until the rubber abutment plate 37 touches the top surface of the iron core. Push the slide plate 32 down to compress the spring 38 to the required elasticity, release the insert rod 34, and use the spring 35 to reset so that the insert rod 34 is inserted into the positioning groove 31 and the slot 33, fix the deformation state of the slide plate 32 and the spring 38, and apply a uniform tension force around the iron core.

[0044] Step 4: Pull the insertion rod 34 to disengage from the positioning groove 31 and slot 33, remove the slide plate 32 and the abutment plate 37 from the guide rod 214, release the tension, press the rotating plate 216 to adjust the guide rod 214 to be coaxial with the bottom block 24, release its contact with the iron core, pull the guide rod 214 upward to disengage the bottom block 24 from the positioning hole 22 and the square magnetic block 23, after disassembling all the guide components, remove the stacked iron core from the base 21.
