Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, specifically to a device for removing insulating varnish from transformer cores. Background Technology

[0002] Removing the insulating varnish from the iron core is a crucial step in the transformer manufacturing process. With the continuous progress and development of the power industry, the quality and performance requirements for transformers are also gradually increasing. As the core component of a transformer, the quality of its insulating varnish treatment directly affects subsequent processing and the final performance of the transformer. Therefore, ensuring the complete removal of the insulating varnish from the iron core has become a critical and indispensable step in the transformer manufacturing process.

[0003] Traditional methods for removing insulating varnish from iron cores have several problems. Some manual grinding methods are extremely inefficient, requiring significant manpower and time. Furthermore, manual operation makes it difficult to ensure uniform varnish removal, easily leading to uneven core surfaces and affecting subsequent assembly and use. Moreover, during manual grinding, operators are exposed to varnish residue and dust for extended periods, posing potential health hazards. Additionally, the lack of effective collection and treatment mechanisms for the varnish residue and dust generated during the removal process means that accumulated residue and dust may re-adhere to the core surface, affecting the quality of varnish removal and potentially disrupting the normal operation of the internal mechanical structure, thus reducing the device's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a device for removing insulating varnish from transformer cores used in transformer manufacturing, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for removing insulating varnish from the core of a transformer, comprising a housing, a core clamping part, and an insulating varnish removal part. A support leg is fixedly installed on the bottom outer wall of the housing, and a door is provided on the housing. A support pad is fixedly installed at the bottom of the support leg. The core clamping part is located at the top of the housing, and the insulating varnish removal part is located in the housing.

[0006] Preferably, the core clamping part specifically includes: a fixing block one, fixedly installed on the top outer wall of the housing; a fixing block two, fixedly installed on the top outer wall of the housing; sliding holes, respectively opened on fixing block one and fixing block two; and a clamping sleeve, fixedly installed on the top of the housing. The clamping sleeve plays an important role in the entire transformer core insulation varnish removal device. When it cooperates with other components of the core clamping part, through the coordinated work of springs, clamping slide rods, etc., when the core is placed between the clamping frames, the springs can make the clamping slide rods slide in the sliding holes, so that the clamping frames can adaptively and firmly clamp the core, ensuring the stability of the core position during the insulation varnish removal process.

[0007] Preferably, a clamping slide rod is slidably connected inside the sliding hole. One end of the clamping slide rod is fixedly installed with a limit plate, and the other end of the clamping slide rod movably passes through the outer wall of the clamping sleeve and extends into the interior of the clamping sleeve. The other end of the clamping slide rod is respectively fixedly connected to a clamping frame one and a clamping frame two. A shaft is fixedly connected circumferentially at equal intervals between the inner walls of the clamping frame one and the clamping frame two. A rubber sleeve is fixedly fitted on the outer wall of the shaft. A spring is movably fitted on the outer wall of each clamping slide rod. One end of the spring is fixedly connected to a fixing block one and a fixing block two, and the other end of the spring is fixedly connected to the outer wall of the clamping sleeve. A rubber sleeve is provided, which cooperates with the shaft and is installed between the inner walls of the clamping frame one and the clamping frame two. When the iron core is placed in the clamping part, due to the elastic force of the spring, the clamping slide rod pushes the clamping frame one and the clamping frame two to move towards the iron core, and the rubber sleeve will contact the surface of the iron core. The rubber sleeve is soft and has a certain friction, which can firmly clamp the iron core without damaging the surface of the iron core, ensuring the stability of the iron core position during the removal of the insulating varnish.

[0008] Preferably, the insulating varnish removal section specifically includes: a motor mounting bracket, fixedly installed on the bottom outer wall of the housing; a feed hole, opened at the top of the housing; and a motor, located on the bottom wall of the housing.

[0009] Preferably, the motor is fixedly installed inside the motor mounting bracket. A rotating shaft is fixedly connected to the motor's output end. The other end of the rotating shaft movably penetrates the bottom outer wall of the housing and extends into the housing. A rotating disk is fixedly connected to the other end of the rotating shaft. The feed hole is connected to the clamping sleeve. The motor is stably mounted on the bottom outer wall of the housing via the motor mounting bracket, and its output end is connected to the rotating shaft, which effectively transmits power. The rotating shaft drives the rotating disk to rotate, providing a stable rotational power source for the entire insulating varnish removal process.

[0010] Preferably, a receiving box is fixedly installed on the top of the rotating disk, a receiving drawer is slidably connected inside the receiving box, a receiving opening is opened on the top of the receiving box, the receiving opening is connected to the receiving drawer, a paint scraper sleeve is fixedly installed on the top of the receiving box, through grooves are opened on both outer walls of the paint scraper sleeve, the paint scraper sleeve is connected to the receiving opening, and a support plate is fixedly connected to the top of the receiving box.

[0011] Preferably, a guide rod is fixedly connected between the support plate and the outer wall of the paint scraper sleeve. An opening is provided on the support plate. A fixing frame is fixedly installed on the outer wall of the support plate. A cylinder is fixedly installed inside the fixing frame. The telescopic end of the cylinder moves through one side of the support plate and extends to the other side of the support plate. A sliding plate is fixedly connected to the telescopic end of the cylinder.

[0012] Preferably, the sliding plate is movably fitted onto the outer wall of the guide rod. The sliding plate has a circular hole, and a support rod is slidably connected inside the circular hole. A scraper is fixedly connected to one end of the support rod, and a circular limiting plate is fixedly connected to the other end of the support rod. The circular limiting plate is adapted to the through-hole. A return spring is movably fitted onto the outer wall of the support rod. One end of the return spring is fixedly connected to the circular limiting plate, and the other end of the return spring is fixedly connected to the sliding plate. The scraper is adapted to the through-groove and is connected to the support rod, the circular limiting plate, and the return spring. Under the action of the cylinder, the sliding plate moves on the guide rod. The sliding motion drives the scraper. When the scraper removes the insulating varnish from the iron core, the return spring allows the scraper to adaptively adjust the pressure when encountering insulating varnish of different thicknesses or minor unevenness on the iron core surface, ensuring the stability and effectiveness of the scraping process. At the same time, the scraper is matched with the through groove on the scraping sleeve, allowing the scraped insulating varnish to fall into the receiving drawer of the receiving box through the through groove. This design facilitates the timely collection of insulating varnish debris, preventing debris from accumulating in the device and affecting subsequent operations and causing secondary pollution to the iron core. It also ensures a clean working environment and improves the efficiency and quality of the entire device in removing insulating varnish.

[0013] This utility model provides a device for removing insulating varnish from transformer cores used in transformer manufacturing. It has the following beneficial effects:

[0014] (1) This utility model uses a core clamping part that is fixed to the top of the box by fixing block one and fixing block two. The clamping slide rod in the sliding hole can slide therein. The limiting plate at one end prevents the clamping slide rod from sliding excessively. The other end passes through the clamping sleeve and connects clamping frame one and clamping frame two. Rubber sleeves are fitted on the circumferentially equidistant shafts between the inner walls of clamping frame one and clamping frame two. This design can effectively and stably clamp the core. On the one hand, the rubber sleeve can increase the friction with the core and prevent the core from loosening during the removal of insulating varnish. On the other hand, the circumferentially equidistant shafts can adapt to cores of different shapes and sizes, ensuring all-round fixation of the core. In addition, the spring fitted on the clamping slide rod is connected to the fixing block at one end and to the outer wall of the clamping sleeve at the other end. The elasticity of the spring can allow the clamping frame to automatically adjust within a certain range to adapt to cores of different thicknesses. It is also more convenient to place and remove the core without complicated adjustment operations, thus improving work efficiency and applicability of the device.

[0015] (2) This utility model uses a motor to drive the rotating shaft to rotate, which in turn makes the rotating disk rotate. This structural design makes the power transmission stable and reliable. A receiving box is set on the rotating disk. The receiving drawer in the receiving box can easily collect the removed insulating varnish and other debris. The receiving port at the top of the receiving box is connected to the receiving drawer, ensuring that the debris can smoothly enter the receiving drawer. The paint scraping sleeve is connected to the receiving port, which can effectively guide the insulating varnish and other debris into the receiving box during the paint scraping process. The through grooves on both sides of the paint scraping sleeve are adapted to the scraper. When the cylinder pushes the slide plate to move along the guide rod, the scraper can scrape off the insulating varnish on the iron core through the through groove. This design can control the paint scraping action of the scraper. The return spring on the outer wall of the support rod can reset the scraper after it completes one paint scraping action, preparing it for the next paint scraping. The whole process is efficient and can ensure a good paint scraping effect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1: A preferred embodiment of the transformer core insulation varnish removal device provided by this utility model is as follows: Figure 1-4 As shown: A transformer core insulation varnish removal device includes a housing 1, a core clamping part 3, and an insulation varnish removal part 4. A support leg 2 is fixedly installed on the bottom outer wall of the housing 1, and a door 5 is opened on the housing 1. A support pad is fixedly installed at the bottom of the support leg 2. The core clamping part 3 is located at the top of the housing 1. The insulation varnish removal part 4 is located in the housing 1.

[0024] The iron core clamping part 3 specifically includes: a first fixing block 311, which is fixedly installed on the top outer wall of the housing 1; a second fixing block 313, which is fixedly installed on the top outer wall of the housing 1; a sliding hole 312, which is respectively opened on the first fixing block 311 and the second fixing block 313; and a clamping sleeve 315, which is fixedly installed on the top of the housing 1.

[0025] A clamping slide rod 316 is slidably connected inside the sliding hole 312. A limit plate 314 is fixedly installed at one end of the clamping slide rod 316. The other end of the clamping slide rod 316 movably passes through the outer wall of the clamping sleeve 315 and extends into the interior of the clamping sleeve 315. A clamping frame 1 318 and a clamping frame 2 3112 are fixedly connected to the other end of the clamping slide rod 316 respectively. A shaft 319 is fixedly connected circumferentially between the inner walls of the clamping frame 1 318 and the clamping frame 2 3112. A rubber sleeve 3111 is fixedly fitted on the outer wall of the shaft 319. A spring 317 is movably fitted on the outer wall of the clamping slide rod 316. One end of the spring 317 is fixedly connected to the fixing block 1 311 and the fixing block 2 313 respectively. The other end of the spring 317 is fixedly connected to the outer wall of the clamping sleeve 315.

[0026] In this embodiment, when the iron core to be processed is placed above the clamping sleeve 315 through the feed hole 412, the weight of the iron core or the slight downward pressure from the operator causes the iron core to press down on the rubber sleeve 3111. Due to the downward pressure of the iron core, the clamping frame 1 318 and the clamping frame 2 3112 are subjected to an outward force, which drives the clamping slide rod 316 to slide in the sliding hole 312. At the same time, the spring 317 is compressed. The elastic force generated by the spring 317 reacts to the clamping slide rod 316, so that the rubber sleeve 3111 on the shaft 319 is tightly attached to the outer wall of the iron core, thereby stably clamping the iron core in the clamping sleeve 315. The elastic effect of the spring can automatically adjust the clamping frame within a certain range to adapt to iron cores of different thicknesses, and it is more convenient to place and remove the iron core without complicated adjustment operations, thus improving work efficiency and the applicability of the device.

[0027] Example 2: Based on Example 1, a preferred embodiment of the transformer core insulation varnish removal device provided by this utility model is as follows: Figure 1-4 As shown: The insulating varnish removal unit 4 specifically includes: a motor mounting bracket 4118, which is fixedly installed on the bottom outer wall of the housing 1; a feed hole 412, which is opened on the top of the housing 1; and a motor 411, which is set on the bottom wall of the housing 1.

[0028] The motor 411 is fixedly installed inside the motor mounting bracket 4118. The output end of the motor 411 is fixedly connected to the rotating shaft 413. The other end of the rotating shaft 413 movably passes through the bottom outer wall of the box 1 and extends into the interior of the box 1. The other end of the rotating shaft 413 is fixedly connected to the rotating disk 414. The feed hole 412 is connected to the clamping sleeve 315.

[0029] A receiving box 415 is fixedly installed on the top of the rotating disk 414. A receiving drawer 416 is slidably connected inside the receiving box 415. A receiving port 417 is opened on the top of the receiving box 415 and is connected to the receiving drawer 416. A paint scraper sleeve 4113 is fixedly installed on the top of the receiving box 415. A through groove 4117 is opened on both outer walls of the paint scraper sleeve 4113 and is connected to the receiving port 417. A support plate 419 is fixedly connected to the top of the receiving box 415.

[0030] A guide rod 4111 is fixedly connected between the support plate 419 and the outer wall of the paint scraper sleeve 4113. The support plate 419 has an opening. A fixing frame is fixedly installed on the outer wall of the support plate. A cylinder 418 is fixedly installed inside the fixing frame. The telescopic end of the cylinder 418 moves through one side of the support plate 419 and extends to the other side of the support plate 419. A sliding plate 4112 is fixedly connected to the telescopic end of the cylinder 418.

[0031] The slide plate 4112 is movably fitted onto the outer wall of the guide rod 4111. The slide plate 4112 has a circular hole, and a support rod 4115 is slidably connected inside the circular hole. One end of the support rod 4115 is fixedly connected to a scraper 4114, and the other end of the support rod 4115 is fixedly connected to a circular limiting plate. The circular limiting plate is adapted to the through opening. A return spring 4116 is movably fitted onto the outer wall of the support rod 4115. One end of the return spring 4116 is fixedly connected to the circular limiting plate, and the other end of the return spring 4116 is fixedly connected to the slide plate 4112. The scraper 4114 is adapted to the through groove 4117.

[0032] In this embodiment, the cylinder 418 operates, pushing the slide plate 4112 to move along the guide rod 4111. When the slide plate 4112 moves, the support rod 4115 drives the scraper 4114 to extend or retract along the through groove 4117 under the action of the return spring 4116. When the scraper 4114 extends, it can contact the surface of the iron core. As the rotating disk 414 rotates, the iron core remains fixed in the clamping part. With the cooperation of the cylinder 418 and the return spring 4116, the scraper 4114 continuously scrapes the insulating varnish on the surface of the iron core. The scraped insulating varnish falls into the receiving drawer 416 through the scraper sleeve 4113 and the receiving port 417, realizing the removal and collection of the insulating varnish. The return spring on the outer wall of the rod can reset the scraper after it completes one scraping action, preparing it for the next scraping action. The whole process is efficient and can ensure a good scraping effect.

[0033] Working principle: Spring 317 is in its naturally extended state. Clamping slide rod 316 is positioned within sliding hole 312. There is a certain gap between clamping frame one 318 and clamping frame two 3112. When the iron core to be processed is placed above clamping sleeve 315 through feed hole 412, the weight of the iron core or the slight downward pressure from the operator causes the iron core to press down on rubber sleeve 3111. Due to the downward pressure of the iron core, clamping frame one 318 and clamping frame two 3112 are subjected to outward force, causing clamping slide rod 316 to slide within sliding hole 312. At the same time, spring 317 is compressed. The elastic force generated by spring 317 reacts to clamping slide rod 316, causing rubber sleeve 3111 on shaft 319 to tightly adhere to the outer wall of iron core, thereby stably clamping the iron core within clamping sleeve 315. This design can accommodate iron cores of different sizes, automatically adjusting the clamping force through the elasticity of the spring. Motor 411 starts, driving the rotation... Rotating shaft 413 drives rotating disk 414 to rotate. Cylinder 418 operates, pushing slide plate 4112 to move along guide rod 4111. When slide plate 4112 moves, it drives scraper 4114 to extend or retract along through groove 4117 under the action of return spring 4116 via support rod 4115. When scraper 4114 extends, it can contact the surface of iron core. As rotating disk 414 rotates, iron core remains fixed in clamping part. With the cooperation of cylinder 418 and return spring 4116, scraper 4114 continuously scrapes the insulating varnish on the surface of iron core. The scraped insulating varnish falls into collection drawer 416 through scraper sleeve 4113 and collection port 417, realizing the removal and collection of insulating varnish. Throughout the process, motor 411 continuously provides rotational power to rotating disk 414, and cylinder 418 and return spring 4116 work together to control the scraping action of scraper 4114.
