Description

Technical Field

[0001] This invention relates to the field of transformer manufacturing technology, specifically to an automated transformer core lamination pressing machine. Background Technology

[0002] Transformer cores are typically made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and coated with insulating varnish. The core laminations are an important part of the transformer structure, and their main function is to form the transformer's magnetic circuit and reduce eddy current losses. The quality of the laminations directly affects the transformer's permeability, losses, and operational stability. Therefore, the core lamination process plays a crucial role in transformer production.

[0003] In the Chinese patent with publication number CN111081467B, entitled "An automatic feeding device for the production of silicon steel sheets for transformer core lamination", the patent achieves automated and orderly feeding operation through the cooperation of vertical feeding device, horizontal feeding device and magnetic feeding device, without the need for manual operation, thus effectively achieving high-intensity and high-precision automated operation. During the production of silicon steel sheets, dust and moisture often adsorb onto their surface. This patent directly stacks the silicon steel sheets during lamination, which can easily damage the insulating protective layer on the surface of the silicon steel sheets due to dust. Furthermore, moisture trapped between the stacked sheets can reduce the insulation resistance and lower the production quality of the iron core. In addition, in existing technologies, after the silicon steel sheets are stacked, a fixing clamp and fastening bolts are used to press and fix the stacked silicon steel sheets. When tightening with the fastening bolts, the silicon steel sheets are subjected to uneven force, which reduces the tightness between the silicon steel sheets and affects the forming quality of the iron core.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Equipped with a stacking and pressing assembly, after the silicon steel sheets are stacked, the lower pressure plate is connected and fixed to the extension rod. The horizontal motor drives the horizontal screw to rotate, realizing the lateral movement of two adjusting plates along the support slide rod. The vertical motor drives the vertical screw to rotate, realizing the longitudinal movement of the assembly frame along the vertical slide rod. Under the connection of the connecting rod, and with the help of the telescopic electric push rod, the lower pressure plate is moved, so that the lower pressure plate is evenly distributed on the top of the stacked silicon steel sheets. The lower pressure plate is lowered by the lifting cylinder to ensure the uniformity of the downward pressure, ensure the tightness between the silicon steel sheets, eliminate interlayer gaps, improve the continuity of the magnetic circuit, and improve the production quality of the transformer core. Moreover, before the pressing process, by increasing or decreasing the number of extension rods, and with the flexible adjustment of the position of the assembly plate by the horizontal and vertical motors, the lower pressure plate can press the cores of different sizes, making the equipment widely applicable. During the stacking of silicon steel sheets, as the thickness of the silicon steel sheets increases, the lifting cylinder synchronously drives the assembly plate to rise. The lifting cylinder is multi-functional; under the connection and conveying action of the air supply pipe and the connecting box, the dry air generator delivers dry air into the dehumidification box. The dry air is ejected from the jet hole and diffuses in all directions, carrying away the residual moisture on the surface of the silicon steel sheets, ensuring the dryness of the stacked sheets, avoiding the reduction of insulation resistance due to condensation on the surface of the silicon steel sheets, and improving the quality of the iron core. At the same time, the dry air blows away the dust adsorbed on the surface of the silicon steel sheets, preventing dust from damaging the insulating coating on the surface of the silicon steel sheets during stacking, further improving the quality of the iron core.

[0016] 2. A fixed correction assembly is provided. After the bottom fixing clamp is fixed, the correction plate is connected to the extension rod. At this time, the correction plate connected to the extension rod is located inside the iron core, and the correction plate connected to the correction electric push rod is located outside the iron core. When the silicon steel sheets are stacked, the correction electric push rod and the telescopic electric push rod drive the correction plates inside and outside the iron core to move closer to each other, and periodically clamp the stacked silicon steel sheets. The compression of the correction plate is used to correct the misaligned silicon steel sheets, thereby improving the stacking quality of the iron core. The extension rods can be flexibly disassembled and installed, and the straightening plate can also be directly connected to the extension rods. By increasing or decreasing the number of extension rods, the effective range of the straightening plate can be increased or decreased. The equipment can change the effective range of the straightening plate according to the size of the processed iron core, and has a wide range of applications. When the bottom fixing fixture is fixed, the clamping screw is rotated. Under the connecting drive of the I-shaped slider, the two fixing frames move closer to each other. The fixing fixture is centered and fixed by the clamping of the two fixing frames. During the stacking process, the bottom fixing fixture is prevented from moving due to mechanical vibration, thus ensuring the accuracy of subsequent stacking.

[0017] In summary, in the fixed correction assembly, the moving motor drives the moving screw to rotate, changing the relative position of the two I-beams, enabling the I-beams to support transformer cores of different sizes. In the lamination pressing assembly, by increasing or decreasing the number of extension rods, and in conjunction with the horizontal and vertical motors to flexibly adjust the position of the assembly plate, the lower pressure plate presses the cores of different sizes. The two assemblies work together to improve the overall applicability of the equipment and enhance its practicality. Attached Figure Description

The input terminal of the controller is electrically connected to the output terminal of the external power supply. The controller can control various electrical components, which facilitates the automated control of the equipment.

[0022] The working principle and usage process of this invention are as follows: During processing, the positions of the two I-beams 301 are first adjusted according to the dimensions of the fixed fixture 303. During adjustment, the moving motor 306 is started, which drives the moving screw 305 to rotate. The support rail 1 guides the moving slider 304 to move on the support rail 1. The moving motor 306 changes the relative positions of the two I-beams 301, so that a fixed fixture 303 located at the bottom of the silicon steel laminate 302 is placed on top of the I-beams 301. The movement of the I-beams 301 changes the relative positions of the two I-beams 301. The slider 310 is positioned within the adjustment port 308. Then, the handle 313 is held and the clamping screw 312 is rotated. The clamping screw 312 drives the slider 311 to move closer to each other. Under the connecting drive of the slider 310, the two fixing brackets 307 move closer to each other until the two fixing brackets 307 tightly clamp the bottom fixing fixture 303, thus completing the centering and fixing of the fixing fixture 303. During the stacking process, the bottom fixing fixture 303 is prevented from moving due to mechanical vibration, ensuring the accuracy of subsequent stacking. After the bottom fixing fixture 303 is fixed, the position of the first adjustment bracket 314 on the fixing bracket 307 is changed according to the size of the iron core to be processed, and the position of the second adjustment bracket 320 on the sliding plate 318 is changed. The position change of the first adjustment bracket 314 and the second adjustment bracket 320 is completed by changing the corresponding position of the positioning pin 321 and the positioning hole 319. Then, the straightening plate 317 is connected to the extension rod 216. At this time, the straightening plate 317 connected to the extension rod 216 is located inside the iron core, and the straightening plate 317 connected to the straightening electric push rod 315 is located outside the iron core. When silicon steel sheets are stacked, the position of the stacked silicon steel sheets is easily shifted due to mechanical vibration, which reduces the stacking accuracy. During the stacking of silicon steel sheets, the straightening electric push rod 315 and the telescopic electric push rod 223 drive the straightening plates 317 on the inner and outer sides of the iron core to move closer to each other, periodically clamping the stacked silicon steel sheets. The extrusion of the straightening plates 317 corrects the misaligned silicon steel sheets, improving the stacking quality of the iron core. The extension rod 216 can be flexibly disassembled and installed, and the straightening plate 317 can also be directly connected to the telescopic rod 215. By increasing or decreasing the number of extension rods 216, the effective range of the straightening plate 317 can be increased or decreased. The equipment can change the effective range of the straightening plate 317 according to the size of the iron core being processed, so that the straightening plate 317 on the inner side of the iron core can contact the stacked silicon steel sheets, making it widely applicable. During the stacking of silicon steel sheets, the dry air generator 228 operates. As the thickness of the silicon steel sheets increases, the lifting cylinder 212 synchronously drives the assembly plate 213 to rise, making the dehumidification box 224 slightly higher than the top silicon steel sheet. Under the connection and conveying action of the air supply pipe 227 and the connecting box 226, the dry air generator 228 delivers dry air into the dehumidification box 224. The dry air is sprayed out from the jet hole 225 and diffuses in all directions, carrying away the residual moisture on the surface of the silicon steel sheets, ensuring the dryness of the stacking, avoiding the reduction of insulation resistance due to condensation on the surface of the silicon steel sheets, and improving the quality of the iron core. At the same time, the dry air blows away the dust adsorbed on the surface of the silicon steel sheets, preventing dust from damaging the insulating coating on the surface of the silicon steel sheets during stacking, further improving the quality of the iron core. After all the silicon steel sheets are stacked, the straightening plate 317 connected to the extension rod 216 is removed, the lower pressure plate 217 is connected and fixed to the extension rod 216, and the top fixing clamp 303 is placed on top of the silicon steel stack 302. Then, the horizontal motor 206 and the vertical motor 211 are started. The horizontal motor 206 drives the horizontal screw 205 to rotate. Under the support and guidance of the support slide rod 201 on the support sleeve 203, the two adjusting plates 202 move laterally along the support slide rod 201. At the same time, the vertical motor 211 drives the vertical screw 210 to rotate. Under the support and guidance of the vertical slide rod 207, the assembly frame 208 moves longitudinally along the vertical slide rod 207. Then, in conjunction with the telescopic electric push rod 223, the lower pressure plate 217 is moved to the top of the top fixing clamp 303. Figure 1 As shown, the lifting cylinder 212 then drives the lower pressure plate 217 to descend. The lower pressure plate 217 contacts the top fixing clamp 303 and applies downward pressure to the stacked silicon steel sheets. The lower pressure plate 217 is evenly distributed on the top of the stacked silicon steel sheets to ensure the uniformity of the downward pressure. By applying uniform pressure, the tightness between the silicon steel sheets is ensured, the interlayer gap is eliminated, the magnetic circuit continuity is improved, and the production quality of the transformer core is improved. Moreover, before the pressing process, by increasing or decreasing the number of extension rods 216, and with the flexible adjustment of the position of the assembly plate 213 by the horizontal motor 206 and the vertical motor 211, the lower pressure plate 217 can press-fit cores of different sizes. The equipment has a wide range of applications. In the fixed correction assembly 3, the moving motor 306 drives the moving screw 305 to rotate, changing the relative position of the two I-beams 301, so that the I-beams 301 can bear transformer cores of different sizes. In the lamination pressing assembly 2, by increasing and decreasing the number of extension rods 216, and cooperating with the horizontal motor 206 and the vertical motor 211 to flexibly adjust the position of the assembly plate 213, the lower pressing plate 217 presses the cores of different sizes. The two assemblies cooperate with each other to improve the applicability of the overall equipment and make it highly practical.
