Abstract
Description
Technical Field
[0001] This invention belongs to the field of transformer manufacturing and processing technology, specifically referring to an automatic transformer core cutting machine. Background Technology
[0002] The transformer core is a core component of a transformer. Its function is to conduct magnetic flux and form a magnetic circuit, thereby enabling the efficient conversion of electrical energy between different voltage levels.
[0003] The core is not a single piece of iron, but rather a stack of many silicon steel sheets, each 0.23-0.35mm thick. The core is precisely cut according to the electrical design drawings. If the size or shape is incorrect, it can lead to a non-closed magnetic circuit, or even cause excessive temperature rise, resulting in unstable transformer operation.
[0004] Traditional iron core cutting machines have many limitations and problems in practical applications. First, most traditional equipment relies on manual assistance for feeding, alignment and operation. Second, when switching to iron sheets of different sizes, the positioning device needs to be further adjusted. Furthermore, the iron sheets are prone to sliding or shifting during the cutting process, resulting in finished product errors. Summary of the Invention
[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides an automatic transformer core cutting machine, which at least partially solves the above problems.
[0006] The technical solution adopted by the present invention is as follows: The present invention proposes an automatic transformer core cutting machine, including a cutting component and a positioning clamping component, wherein the upper part of the cutting component is provided with multiple sets of positioning clamping components.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0026] like Figures 1 to 6 As shown, the present invention proposes an automatic transformer core cutting machine, including a cutting component 1 and a positioning clamping component 2, wherein the upper part of the cutting component 1 is provided with multiple sets of positioning clamping components 2; The positioning and clamping assembly 2 is adapted to iron sheets of different sizes. The positioning and clamping assembly 2 includes a sliding platform 203, a lower pressure plate 208 and an upper pressure plate 214. The lower pressure plate 208 is located on the upper part of the sliding platform 203 and the upper pressure plate 214 is located on the upper part of the lower pressure plate 208.
[0027] Furthermore, the cutting assembly 1 includes a bottom frame 101, a platform 102, and a rotating frame 103; The platform 102 is fixed to the upper part of the bottom frame 101, and the rotating frame 103 consists of two sets of vertical plates, with the two sets of vertical plates of the rotating frame 103 fixed to the upper part of the platform 102, one in front of the other.
[0028] Furthermore, the cutting assembly 1 also includes a rotating motor 104, a gear set 105, a lower roller 106, and an upper roller 107; The rotating motor 104 is fixed to any side of the rotating frame 103, the gear set 105 is fixed to the front of the rotating motor 104, the lower roller 106 is located at the front of the gear set 105, the upper roller 107 is located at the front of the gear set 105, and the upper roller 107 is located above the lower roller 106.
[0029] Furthermore, the cutting assembly 1 also includes a roller group 108. One or more roller groups 108 are provided on the upper part of the lower roller 106 and the upper roller 107. Both sides of the roller group 108 are provided with slits for cutting iron sheets.
[0030] In this embodiment, the platform 102 is first fixed to the upper part of the bottom frame 101, and the rotating frame 103 consists of two sets of vertical plates. The two sets of vertical plates of the rotating frame 103 are fixed to the upper part of the platform 102, one in front and one behind. The rotating motor 104 is fixed to either side of the rotating frame 103, so the rotating motor 104 can work on the platform 102 and drive the parts inside the rotating frame 103 to rotate.
[0031] Since the rotating motor 104 is fixed to either side of the rotating frame 103, and the gear set 105 is fixed to the front of the rotating motor 104, when the rotating motor 104 starts to rotate, it will drive the gear set 105 at its front to rotate. Subsequently, since the lower roller 106 and the upper roller 107 are located at the front of the gear set 105, when the rotating motor 104 drives the gear set 105 to rotate, the gear set 105 will drive the lower roller 106 and the upper roller 107 at its front to rotate.
[0032] The lower roller 106 and the upper roller 107 are provided with one or more sets of roller groups 108, and both sides of the roller group 108 are provided with slits for cutting the iron sheet. The slits of the roller group 108 on the lower roller 106 and the upper roller 107 are set in opposite directions. Therefore, when the iron sheet passes through the roller group 108 on the lower roller 106 and the upper roller 107, it will be subjected to a rolling pressure by the roller group 108. This pressure acts on the iron sheet, forming a cut on the iron sheet.
[0033] The positioning and clamping assembly 2 includes a sliding platform 203, a lower pressure plate 208, and an upper pressure plate 214. At this time, iron sheets of different sizes are placed into the positioning and clamping assembly 2, and are firmly clamped by the lower pressure plate 208 and the upper pressure plate 214. Then, the gear set 105 drives the lower roller 106 and the upper roller 107 to rotate synchronously, clamping and pushing the iron sheets forward. Finally, the iron sheets are subjected to rolling pressure at the cut of the roller set 108, achieving continuous shearing.
[0034] In summary, the multiple positioning and clamping components 2 can be adapted to iron sheets of different sizes to ensure stable feeding. The upper and lower roller groups 108 adopt a reverse cutting setting and apply pressure in both directions to cut, ensuring a neat and smooth cut surface. Key parts such as the roller group 108 and the positioning and clamping components 2 are easy to replace and maintain.
[0035] Furthermore, the positioning and clamping assembly 2 also includes a fixing assembly 201 and a slide rail 202; In this configuration, two sets of fixing components 201 are fixedly connected to the middle of the two sets of vertical plates of the rotating frame 103, and the two sets of fixing components 201 are fixedly connected to the middle of the two sets of vertical plates of the rotating frame 103 one in front of the other. The slide rail 202 is fixed between the two sets of vertical plates of the rotating frame 103, and the slide rail 202 is fixed to the front of the fixing component 201.
[0036] Furthermore, the positioning and clamping assembly 2 also includes an upper connecting rod 204, a mounting platform 205, a first support rod 206, and a first spring 207; The sliding platform 203 is movably connected to the upper part of the slide rail 202. The upper connecting rod 204 is located in the middle of the sliding platform 203. The mounting surface 205 is fixed to the top of the upper connecting rod 204. The first support rod 206 is movably connected to the front of the mounting surface 205. The lower pressure plate 208 is fixed to the top of the first support rod 206. The first spring 207 is connected to the lower pressure plate 208 and the mounting surface 205, and the first spring 207 is also fixed to the first support rod 206.
[0037] Furthermore, the positioning and clamping assembly 2 also includes an upper connecting rod 210, an outer hanging plate 211, a second support rod 212, and a second spring 213; The upper connecting rod 210 is located at the rear of the mounting platform 205, the outer hanging plate 211 is fixedly connected to the top of the upper connecting rod 210, the second support rod 212 is movably connected to the front of the outer hanging plate 211, the upper pressure plate 214 is fixedly connected to the bottom of the second support rod 212, the second spring 213 is connected between the outer hanging plate 211 and the upper pressure plate 214, and the second spring 213 is fixedly connected to the second support rod 212.
[0038] Furthermore, a set of second rollers 215 are rolledly connected in the middle of the upper platen 214, and a set of first rollers 209 are rolledly connected in the middle of the lower platen 208.
[0039] In this embodiment, since two sets of fixing components 201 are fixedly connected to the middle of the two sets of vertical plates of the rotating frame 103, and the two sets of fixing components 201 are fixedly connected to the middle of the two sets of vertical plates of the rotating frame 103 one in front and one behind, the slide rail 202 is fixed between the two sets of vertical plates of the rotating frame 103, and the slide rail 202 is fixed to the front of the fixing component 201, and the sliding platform 203 is movably connected to the upper part of the slide rail 202, so that the sliding platform 203 can slide back and forth in the middle of the rotating frame 103.
[0040] The upper connecting rod 204 is located in the middle of the sliding platform 203. When the sliding platform 203 slides back and forth in the middle of the rotating frame 103, the upper connecting rod 204 will also slide back and forth in the middle of the rotating frame 103 along with the sliding platform 203. The mounting surface 205 is fixed to the top of the upper connecting rod 204. When the upper connecting rod 204 moves, the mounting surface 205 will move along with the upper connecting rod 204.
[0041] The first support rod 206 is movably connected to the front of the mounting platform 205, and the lower platen 208 is fixed to the top of the first support rod 206. When the mounting platform 205 moves, the above-mentioned components will start to move accordingly. Then, since the first spring 207 is connected to the lower platen 208 and the mounting platform 205, and the first spring 207 is also fixed to the first support rod 206, when there is no iron plate on the upper part of the lower platen 208, the first spring 207 between the lower platen 208 and the mounting platform 205 will push the lower platen 208 to move upward.
[0042] The upper connecting rod 210 is located at the rear of the mounting platform 205. The outer hanging plate 211 is fixed to the top of the upper connecting rod 210. The two support rods 212 are movably connected to the front of the outer hanging plate 211. When the mounting platform 205 moves back and forth on the upper part of the slide rail 202, the above-mentioned parts will also move back and forth. Furthermore, the upper pressure plate 214 is fixed to the bottom of the second support rod 212. The second spring 213 is connected between the outer hanging plate 211 and the upper pressure plate 214. When there is no iron sheet between the upper pressure plates 214, the elastic force of the second spring 213 will act on the upper pressure plate 214, causing the upper pressure plate 214 to move downward.
[0043] At this time, an iron sheet is placed between the upper pressure plate 214 and the lower pressure plate 208. The iron sheet will be clamped between the upper pressure plate 214 and the lower pressure plate 208 due to the elastic force of the first spring 207 and the second spring 213.
[0044] In summary, the fixed component 201 is fixed to the middle of the rotating frame 103, arranged in a front-to-back configuration to provide a stable fulcrum. The slide rail 202 is connected to the fixed component 201, supports the sliding platform 203 to slide back and forth, and provides a guiding function. The sliding platform 203 is movably connected to the slide rail 202 and is the basic moving platform of the entire positioning and clamping component 2.
[0045] The upper connecting rod 204 and the mounting platform 205 are used to support the lower pressure plate 208. The first support rod 206 and the lower pressure plate 208 are connected to the mounting platform 205 by the first spring 207 to achieve elastic upward lifting. The first roller 209 is installed in the middle of the lower pressure plate 208 to assist in conveying iron sheets or reduce friction.
[0046] The upper connecting rod 210 and the outer hanging plate 211 are structural platforms used to support the upper pressure plate 214. The second support rod 212 and the upper pressure plate 214 are elastically pressed down by the second spring 213. The second roller 215 is installed in the middle of the upper pressure plate 214 and cooperates with the first roller 209 to achieve smooth pressing.
[0047] With two sets of spring systems (upper pressure + lower support), iron sheets of different thicknesses and sizes can be automatically clamped without frequent adjustments. The sliding platform 203 slides back and forth on the slide rail 202, and can flexibly position the pressure plate area according to the feeding position of the iron sheet to adapt to different working conditions. Rollers (209, 215) are provided between the upper and lower pressure plates, which can assist the iron sheet to move forward in the pressing state, reduce friction and scratches, and improve the quality of finished products.
