Description

Technical Field

[0001] This invention relates to the field of iron core production technology, and in particular to a transformer iron core production equipment. Background Technology

[0002] The transformer core is an indispensable magnetic circuit component in a transformer. It is typically made of laminated soft magnetic materials such as silicon steel sheets, and its processing quality directly affects the transformer's performance and service life. Currently, the conventional production process for transformer cores usually includes the following steps: First, the coiled raw steel plates are uncoiled, leveled, and then transported to the cutting station; then, the steel plates are cut into sheet-like semi-finished products of specific shapes using laser cutting or punching methods; next, the semi-finished products are transferred to the stamping station for stamping to obtain iron core sheets of the required shape; finally, multiple iron core sheets are stacked and fixed to a certain thickness to form a complete transformer core.

[0003] In existing transformer core production equipment, laser cutting and stamping are typically performed at two separate workstations or on two separate machines. The semi-finished products after cutting need to be transferred to the stamping station via conveyor belts, robotic arms, or other transfer devices. This process not only increases the equipment footprint and production cycle time, but also makes the semi-finished products prone to positional shifts or damage during transfer, affecting subsequent stamping accuracy and core quality. Furthermore, although some existing equipment integrates laser cutting and stamping into the same machine, the motion trajectory control of the laser cutting head largely relies on the CNC system driving XY axis linkage. For contour cutting, the control system is complex and costly. Especially when frequent switching between different core sizes is required, the processing program needs to be rewritten or adjusted, resulting in lengthy changeover times and constraining production efficiency.

[0004] On the other hand, during laser cutting, to ensure the accuracy of the cutting contour, the movement trajectory of the laser cutting head needs to strictly conform to the preset shape path. Some existing contour cutting devices use a mechanical template method, that is, using template rollers to walk along the edge of the contour template, thereby guiding the cutting head to move synchronously. However, such devices have the following shortcomings in practical applications: First, the transmission chain between the template roller and the cutting head is usually long, and the multi-stage transmission links are prone to introducing cumulative errors, resulting in a deviation between the actual trajectory of the cutting head and the contour of the template, affecting the dimensional accuracy of the semi-finished product; Second, when processing iron cores with different side lengths, it is necessary to replace the template and adjust the initial relative position of the template roller and the cutting head accordingly. Existing devices often require manual operation of multiple components during adjustment, making the adjustment steps cumbersome and difficult to ensure the consistency of the synchronous movement of the two after adjustment; Third, the tightness of the fit between the template roller and the template depends on the pre-pressure provided by elastic elements such as springs. After changing to different sized templates, the initial compression of the springs needs to be reset. Existing devices lack convenient and precise adjustment methods for this, which can easily lead to distortion of the contour due to insufficient fit.

[0005] Furthermore, in existing equipment, waste material from the stamping station typically needs to be collected and cleaned separately. If not cleaned in a timely manner, waste material can easily accumulate, affecting the normal operation of the equipment and operational safety. Although some equipment uses conveyor belts to carry the waste material out along with the raw steel plates, the removal and stacking of the stamped iron chips still requires manual labor or independent robotic arms, indicating that there is still room for improvement in the overall level of automation. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention discloses a transformer core production equipment that integrates laser contour cutting and stamping, features precise and easily adjustable contour transmission, and can quickly adapt to the production of different sizes and specifications. The technical solution adopted by this invention is as follows: a transformer core production equipment, comprising an equipment shell and a main body mechanism. The main body mechanism includes an internal frame fixedly installed inside the equipment shell. The main body mechanism is equipped with a laser mechanism for shaping the incoming raw material steel plate and a forming mechanism for stamping the laser-cut semi-finished product to form a transformer core. The main structure includes a lifting frame fixedly installed on an internal frame, and an upper connecting frame is fixedly installed on the lifting frame.

[0007] Furthermore, the main structure also includes a lifting motor fixedly installed on the lifting frame, a lifting screw fixedly installed on the output end of the lifting motor, the lifting screw being rotatably installed with the internal frame, a lifting support plate being slidably installed on the internal frame, and the lifting support plate and the lifting screw forming a threaded transmission.

[0008] The lifting motor drives the lifting screw to rotate, which can move the lifting pallet up and down along the internal frame. The raw steel plate to be processed is transported to the lifting pallet through the external conveying mechanism. Then, the raw steel plate is cut into semi-finished products of the required size by the laser mechanism. After that, the lifting pallet is lowered, and the semi-finished products are placed on the bottom support by the external robotic arm.

[0009] Furthermore, the laser mechanism includes an upper motor frame fixedly mounted on an upper connecting frame, a contour motor fixedly mounted on the upper motor frame, an upper transmission wheel fixedly mounted on the motor shaft of the contour motor, an inner rotating column fixedly mounted on the upper transmission wheel, an upper rotating frame fixedly mounted on the inner rotating column, a side transmission column rotatably mounted on the upper connecting frame, and an upper transmission belt wrapped around the side transmission column and the upper transmission wheel.

[0010] Furthermore, the laser mechanism also includes a lower connecting frame fixedly installed below the lifting frame, a lower transmission wheel rotatably mounted on the lower connecting frame, a lower transmission belt wrapped around the lower transmission wheel and the side transmission column, and a lower rotating column fixedly installed below the lower transmission wheel.

[0011] Furthermore, the laser mechanism also includes a dynamic bracket slidably mounted on the upper rotating frame, an upper rack fixedly mounted on the dynamic bracket, a fitting roller rotatably mounted below the dynamic bracket via a rolling bearing, a central transmission wheel rotatably mounted on the inner rotating column, an upper adjusting gear fixedly mounted on the central transmission wheel, the upper adjusting gear meshing with the upper rack, an upper placement frame fixedly mounted on the lifting frame, a contoured iron core fixedly mounted on the upper placement frame, and the fitting roller fitting against the outer edge of the contoured iron core.

[0012] Furthermore, the laser mechanism also includes an adjusting motor fixedly mounted on the upper rotating frame, an inner sliding strip slidably mounted inside the upper rotating frame, an adjusting screw fixedly mounted on the motor shaft of the adjusting motor, an internal thread provided inside the inner sliding strip, the inner sliding strip and the adjusting screw forming a threaded transmission, an end block fixedly mounted at the end of the inner sliding strip, and a tight-fitting spring provided between the end block and the dynamic support.

[0013] Furthermore, the laser mechanism also includes a side column rotatably mounted on the upper connecting frame, a side drive belt wrapped around the central drive wheel and the side column, a central drive wheel rotatably mounted on the lower rotating column, a lower adjusting gear fixedly mounted on the central drive wheel, and a lower side belt wrapped around the central drive wheel and the side column.

[0014] Furthermore, the laser mechanism also includes a lower rotating frame fixedly installed below the lower rotating column, a sliding block slidably installed below the lower connecting frame, a lower rack fixedly installed on the sliding block, the lower rack meshing with the lower adjusting gear, a laser bracket slidably installed on the lower rotating frame, a laser head fixedly installed below the laser bracket, an adjusting electric cylinder fixedly installed on the laser bracket, and the output end of the adjusting electric cylinder fixedly installed with the sliding block.

[0015] Before use, first fix the conforming core, which matches the transformer core to be processed, on the upper placement frame. The spring ensures the contact roller remains in contact with the outer contour of the conforming core. The raw steel plate is then transported to the bottom of the lifting frame via an external conveying mechanism. Initially, the laser head is directly below the contact roller. At this point, the laser head starts, and the conforming motor drives the upper drive wheel and inner rotating column to rotate. The upper drive wheel drives the side drive column via the upper drive belt, and the side drive column drives the lower drive wheel, lower rotating column, and lower rotating frame via the lower drive belt, thus rotating the laser head. At this time, the contact roller and laser head rotate synchronously. Simultaneously, as the contact roller moves along... As the outer contour of the conforming iron core moves, the dynamic support slides along the upper rotating frame, further compressing the spring. At this time, the dynamic support drives the upper adjusting gear and the central transmission wheel to rotate via the upper rack. The central transmission wheel drives the side column to rotate via the side transmission belt. The side column drives the middle transmission wheel and the lower adjusting gear to rotate via the lower belt. The lower adjusting gear drives the lower rack, sliding block, adjusting electric cylinder, laser support, and laser head to move, so that the laser head always stays below the contact roller. Thus, when the contact roller moves a full circle along the outer contour of the conforming iron core, the laser head cuts a semi-finished product with the same size as the outer contour of the conforming iron core onto the raw material steel plate.

[0016] Since the stacked transformer cores need to be of different sizes, transformer cores of different side lengths need to be cut. At this time, the extension and retraction of the electric cylinder can be adjusted to drive the laser bracket and laser head to slide along the lower rotating frame, thereby adjusting the initial horizontal distance between the laser head and the bonding roller. As the laser head moves together with the bonding roller, the horizontal distance between the bonding roller and the laser head remains constant, so as to process transformer cores of different side lengths.

[0017] When machining large or small transformer cores, it is necessary to replace them with different sized conforming cores. At the same time, it is necessary to adjust the initial compression of the contact spring to ensure that the contact roller can always be in close contact with the edge of the conforming core. First, fix the sliding block, and then adjust the motor to drive the adjusting screw to rotate, which will cause the inner sliding strip and the end block to slide relative to the upper rotating frame, thereby adjusting the initial compression of the contact spring.

[0018] Furthermore, the forming mechanism includes a stamping frame fixedly installed on the internal frame, a plurality of stamping electric cylinders fixedly installed on the stamping frame, a lower stamping head fixedly installed on the output end of the stamping electric cylinders, a bottom support fixedly installed on the internal frame, a placement seat fixedly installed on the internal frame, and two placement columns fixedly installed on the placement seat.

[0019] After the semi-finished product is placed on the bottom support, the stamping cylinder extends, driving the lower stamping head to descend. The lower stamping head stamps the semi-finished product, forming a transformer core. The stamped waste falls onto the internal frame. As the raw steel plate is continuously conveyed, the waste is carried out along with it. Then, the external robotic arm places the transformer core on the placement column to complete the stacking.

[0020] The beneficial effects of this invention compared with the prior art are: (1) This invention integrates the laser mechanism and the forming mechanism on the same equipment shell and internal frame. The raw material steel plate transported from the outside is received by the lifting pallet. The laser contour cutting and stamping forming processes are completed in the same equipment in sequence. This eliminates the transfer link of semi-finished products between different work stations or different equipment, shortens the production cycle, reduces the equipment floor space, and avoids the positional deviation or collision damage that may occur during the transfer of semi-finished products. This ensures that the semi-finished products after cutting accurately enter the stamping work station, effectively improving the dimensional accuracy and appearance quality of the final iron core product; (2) This invention uses multi-stage synchronous belt transmission such as upper transmission belt, lower transmission belt, side transmission belt and lower side belt. With the meshing of the upper rack and the upper adjusting gear, and the meshing of the lower rack and the lower adjusting gear, the movement of the fitting roller along the outer contour of the contour iron core is accurately transmitted to the laser head, so that the laser head is always kept directly below the fitting roller synchronously. The movement achieves strict consistency between the cutting trajectory and the contour, and can accurately replicate the outline of the contour iron core. It is especially suitable for the stringent requirements of cutting consistency and repeatability in mass production; (3) By adjusting the extension and retraction of the electric cylinder, the laser support and laser head can be driven to slide along the lower rotating frame, changing the initial horizontal distance between the laser head and the contact roller. Thus, without changing the contour iron core, the cutting and processing of iron cores with different side lengths can be achieved. The adjustment is convenient and quick. When it is necessary to change the contour iron core of different sizes, the initial compression of the close-fitting spring can be accurately adjusted by adjusting the motor to drive the adjustment screw to rotate, which drives the inner sliding strip and the end block to move. This ensures that the contact roller is always closely attached to the edge of the contour iron core, avoiding the distortion of the contour caused by the loose contact. The above two adjustment mechanisms work together to enable the equipment to quickly adapt to the production needs of iron cores of various specifications. The changeover time is short and the adjustment accuracy is high, which improves the versatility and production efficiency of the equipment. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0032] Example: Reference Figures 1-9A transformer core production equipment includes an equipment shell 6 and a main structure. The main structure includes an internal frame 101 fixedly installed inside the equipment shell 6. The main structure is equipped with a laser mechanism for shaping the raw material steel plate 4 that is transported in and a forming mechanism for stamping the semi-finished product after laser cutting to form the transformer core 5. The main structure includes a lifting frame 102 fixedly installed on the internal frame 101, and an upper connecting frame 106 fixedly installed on the lifting frame 102.

[0033] like Figure 3 As shown, the main structure also includes a lifting motor 103 fixedly installed on the lifting frame 102. A lifting screw 104 is fixedly installed on the output end of the lifting motor 103. The lifting screw 104 is rotatably installed with the internal frame 101. A lifting support plate 105 is slidably installed on the internal frame 101. The lifting support plate 105 and the lifting screw 104 form a threaded transmission.

[0034] The lifting motor 103 drives the lifting screw 104 to rotate, which can drive the lifting pallet 105 to rise and fall along the internal frame 101. The raw material steel plate 4 to be processed is transported to the lifting pallet 105 through the external conveying mechanism. Then, the raw material steel plate 4 is cut into semi-finished products of the required size by the laser mechanism. After that, the lifting pallet 105 is lowered, and the semi-finished products are placed on the bottom support 304 by the external robot arm.

[0035] like Figures 4-8 As shown, the laser mechanism includes an upper motor frame 201 fixedly mounted on an upper connecting frame 106. A contour motor 202 is fixedly mounted on the upper motor frame 201. An upper transmission wheel 203 is fixedly mounted on the motor shaft of the contour motor 202. An inner rotating column 208 is fixedly mounted on the upper transmission wheel 203. An upper rotating frame 209 is fixedly mounted on the inner rotating column 208. A side transmission column 205 is rotatably mounted on the upper connecting frame 106. An upper transmission belt 204 is wound around the side transmission column 205 and the upper transmission wheel 203.

[0036] like Figures 4-8 As shown, the laser mechanism also includes a lower connecting frame 223 fixedly installed below the lifting frame 102. A lower transmission wheel 207 is rotatably installed on the lower connecting frame 223. A lower transmission belt 206 is wound around the lower transmission wheel 207 and the side transmission column 205. A lower rotating column 217 is fixedly installed below the lower transmission wheel 207.

[0037] like Figures 4-8As shown, the laser mechanism also includes a dynamic bracket 226 slidably mounted on the upper rotating frame 209. An upper rack 227 is fixedly mounted on the dynamic bracket 226. A contact roller 228 is rotatably mounted below the dynamic bracket 226 via a rolling bearing. A central transmission wheel 210 is rotatably mounted on the inner rotating column 208. An upper adjusting gear 211 is fixedly mounted on the central transmission wheel 210. The upper adjusting gear 211 meshes with the upper rack 227. An upper placement frame 234 is fixedly mounted on the lifting frame 102. A contoured iron core 233 is fixedly mounted on the upper placement frame 234. The contact roller 228 is in contact with the outer edge of the contoured iron core 233.

[0038] like Figures 4-8 As shown, the laser mechanism also includes an adjusting motor 229 fixedly mounted on the upper rotating frame 209. An inner sliding strip 231 is slidably mounted inside the upper rotating frame 209. An adjusting screw 230 is fixedly mounted on the motor shaft of the adjusting motor 229. An internal thread is provided inside the inner sliding strip 231, and the inner sliding strip 231 and the adjusting screw 230 form a threaded transmission. An end block 232 is fixedly mounted at the end of the inner sliding strip 231, and a pressing spring 225 is provided between the end block 232 and the dynamic support 226.

[0039] like Figures 4-8 As shown, the laser mechanism also includes a side column 213 rotatably mounted on the upper connecting frame 106, a side transmission belt 212 wrapped around the center transmission wheel 210 and the side column 213, a middle transmission wheel 215 rotatably mounted on the lower rotating column 217, a lower adjusting gear 216 fixedly mounted on the middle transmission wheel 215, and a lower side belt 214 wrapped around the middle transmission wheel 215 and the side column 213.

[0040] like Figures 4-8 As shown, the laser mechanism also includes a lower rotating frame 218 fixedly installed below the lower rotating column 217. A sliding block 222 is slidably installed below the lower connecting frame 223. A lower rack 224 is fixedly installed on the sliding block 222. The lower rack 224 meshes with the lower adjusting gear 216. A laser bracket 219 is slidably installed on the lower rotating frame 218. A laser head 220 is fixedly installed below the laser bracket 219. An adjusting electric cylinder 221 is fixedly installed on the laser bracket 219. The output end of the adjusting electric cylinder 221 is fixedly installed with the sliding block 222.

[0041] Before use, the conforming core 233, which matches the transformer core 5 to be processed, is first fixed on the upper placement frame 234. The spring 225 is pressed tightly so that the contact roller 228 is always in contact with the outer contour of the conforming core 233. The raw material steel plate 4 is transported to the lower part of the lifting frame 102 through the external conveying mechanism. The laser head 220 is initially located directly below the contact roller 228. At this time, the laser head 220 is started, and the conforming motor 202 drives the upper transmission wheel 203 and the inner rotating column 208 to rotate. The upper transmission wheel 203 drives the side transmission column 205 to rotate through the upper transmission belt 204. The side transmission column 205 drives the lower transmission wheel 207, the lower rotating column 217 and the lower rotating frame 218 to rotate through the lower transmission belt 206, thereby driving the laser head 220 to rotate. At this time, the contact roller 228 and the laser head 220 rotate synchronously. At the same time, as the contact roller 228 moves along the conforming core... As the outer contour of 233 moves, the dynamic support 226 slides along the upper rotating frame 209, and the spring 225 is further compressed. At this time, the dynamic support 226 drives the upper adjusting gear 211 and the central transmission wheel 210 to rotate through the upper rack 227. The central transmission wheel 210 drives the side column 213 to rotate through the side transmission belt 212. The side column 213 drives the middle transmission wheel 215 and the lower adjusting gear 216 to rotate through the lower belt 214. The lower adjusting gear 216 drives the lower rack 224, the sliding block 222, the adjusting electric cylinder 221, the laser support 219, and the laser head 220 to move, so that the laser head 220 always stays below the contact roller 228. Thus, when the contact roller 228 moves a full circle along the outer contour of the conforming iron core 233, the laser head 220 cuts a semi-finished product with the same size as the outer contour of the conforming iron core 233 on the raw material steel plate 4.

[0042] Since the stacked transformer cores 5 require different sizes, transformer cores 5 with different side lengths need to be cut. At this time, the extension and retraction of the electric cylinder 221 can be adjusted to drive the laser bracket 219 and the laser head 220 to slide along the lower rotating frame 218, thereby adjusting the initial horizontal distance between the laser head 220 and the bonding roller 228. As the laser head 220 moves together with the bonding roller 228, the horizontal distance between the bonding roller 228 and the laser head 220 remains constant, so as to process transformer cores 5 with different side lengths.

[0043] When processing large or small transformer cores 5, it is necessary to replace them with different sized conforming cores 233. At the same time, it is necessary to adjust the initial compression of the pressing spring 225 to ensure that the contact roller 228 can always be in close contact with the edge of the conforming core 233. First, fix the sliding block 222, and then adjust the motor 229 to drive the adjusting screw 230 to rotate, which will drive the inner sliding strip 231 and the end block 232 to slide relative to the upper rotating frame 209, thereby adjusting the initial compression of the pressing spring 225.

[0044] like Figure 9 As shown, the forming mechanism includes a stamping frame 301 fixedly installed on the internal frame 101, a plurality of stamping electric cylinders 302 fixedly installed on the stamping frame 301, a lower stamping head 303 fixedly installed on the output end of the stamping electric cylinders 302, a bottom support 304 fixedly installed on the internal frame 101, a placement seat 305 fixedly installed on the internal frame 101, and two placement columns 306 fixedly installed on the placement seat 305.

[0045] After the semi-finished product is placed on the bottom support 304, the stamping cylinder 302 extends, driving the lower stamping head 303 to descend. The lower stamping head 303 stamps the semi-finished product, forming the transformer core 5. The stamped waste falls onto the internal frame 101. As the raw material steel plate 4 is continuously conveyed, the waste is carried out together. Then, the external robot arm places the transformer core 5 on the placement column 306 to complete the stacking.

[0046] Working principle: The lifting motor 103 drives the lifting screw 104 to rotate, which can drive the lifting pallet 105 to rise and fall along the internal frame 101. The raw material steel plate 4 to be processed is transported to the lifting pallet 105 through the external conveying mechanism. Before use, the conforming iron core 233 that matches the transformer iron core 5 to be processed is first fixed on the upper placement frame 234. The close-fitting spring 225 ensures that the contact roller 228 is always in contact with the outer contour of the conforming iron core 233. The raw material steel plate 4 is transported to the upper frame 105 through the external conveying mechanism. The laser head 220 is initially positioned directly below the contact roller 228, below the lifting frame 102. At this point, the laser head 220 starts, and the contouring motor 202 drives the upper drive wheel 203 and the inner rotating column 208 to rotate. The upper drive wheel 203 drives the side drive column 205 to rotate via the upper drive belt 204. The side drive column 205 drives the lower drive wheel 207, the lower rotating column 217, and the lower rotating frame 218 to rotate via the lower drive belt 206, thereby causing the laser head 220 to rotate. The contact roller 228 and the laser head 220 rotate synchronously. Simultaneously, as the contact roller 228 moves along the outer contour of the contoured iron core 233, the dynamic support 226 slides along the upper rotating frame 209, further compressing the contact spring 225. At this time, the dynamic support 226 drives the upper adjusting gear 211 and the central transmission wheel 210 to rotate via the upper rack 227. The central transmission wheel 210 drives the side column 213 to rotate via the side transmission belt 212. The side column 213 rotates via the lower belt 214. The drive wheel 215 and the lower adjusting gear 216 rotate, which in turn drives the lower rack 224, sliding block 222, adjusting cylinder 221, laser bracket 219, and laser head 220 to move. This ensures that the laser head 220 remains below the contact roller 228, so that when the contact roller 228 completes a full circle along the outer contour of the conforming iron core 233, the laser head 220 cuts a semi-finished product with the same dimensions as the outer contour of the conforming iron core 233 from the raw material steel plate 4. Then, the lifting pallet 105 descends, and an external robotic arm places the semi-finished product onto the bottom support 304.

[0047] After the semi-finished product is placed on the bottom support 304, the stamping cylinder 302 extends, driving the lower stamping head 303 to descend. The lower stamping head 303 stamps the semi-finished product, forming the transformer core 5. The stamped waste falls onto the internal frame 101. As the raw material steel plate 4 is continuously conveyed, the waste is carried out together. Then, the external robot arm places the transformer core 5 on the placement column 306 to complete the stacking.

[0048] Since the stacked transformer cores 5 require different sizes, transformer cores 5 with different side lengths need to be cut. At this time, the extension and retraction of the electric cylinder 221 can be adjusted to drive the laser bracket 219 and the laser head 220 to slide along the lower rotating frame 218, thereby adjusting the initial horizontal distance between the laser head 220 and the bonding roller 228. As the laser head 220 moves together with the bonding roller 228, the horizontal distance between the bonding roller 228 and the laser head 220 remains constant, so as to process transformer cores 5 with different side lengths.

[0049] When processing large or small transformer cores 5, it is necessary to replace them with different sized conforming cores 233. At the same time, it is necessary to adjust the initial compression of the pressing spring 225 to ensure that the contact roller 228 can always be in close contact with the edge of the conforming core 233. First, fix the sliding block 222, and then adjust the motor 229 to drive the adjusting screw 230 to rotate, which will drive the inner sliding strip 231 and the end block 232 to slide relative to the upper rotating frame 209, thereby adjusting the initial compression of the pressing spring 225.
