Description

Technical Field

[0001] This application relates to the field of transformer core manufacturing technology, and in particular to a cross-cutting system for cutting silicon steel sheets of the central column type. Background Technology

[0002] The transformer core is the main magnetic circuit component of a transformer, and it is typically made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and an insulating varnish coating. The silicon steel sheet shearing system is used to cut the complete silicon steel strip into perforated core side laminations, center laminations, and yoke laminations to facilitate subsequent stacking of the transformer core.

[0003] In related technologies, refer to Figure 1 A cross-cutting system for cutting column-shaped silicon steel sheets includes an unwinding machine for unwinding silicon steel strip and a worktable located on one side of the unwinding machine. A conveyor belt for conveying the silicon steel strip is mounted on the worktable. Along the length of the conveyor belt on the worktable, a first V-shaped punch, two sets of punching knives, and a second V-shaped punch are sequentially mounted via supports and cylinders. The conveyor belt transports the unwound silicon steel strip to below the first V-shaped punch, the two sets of punching knives, and the second V-shaped punch. The cylinders drive the first V-shaped punch, the two sets of punching knives, and the second V-shaped punch to fall sequentially, cutting the silicon steel strip to obtain a column-shaped silicon steel sheet with holes.

[0004] Regarding the aforementioned technologies, the inventors discovered that during the cutting process of silicon steel strips in the cross-cutting system, the waste material after the silicon steel strips are cut tends to remain on the conveyor belt and leave the conveyor belt together with the finished silicon steel sheets. The finished silicon steel sheets and waste material are mixed together, making it difficult to quickly collect the finished silicon steel sheets, thus affecting the cutting efficiency of the silicon steel sheets. Summary of the Invention

[0005] To address the problem of finished silicon steel sheets and cutting waste being mixed together, making collection inconvenient and easily affecting the cutting efficiency of silicon steel sheets, this application provides a cross-cutting system for cutting central column type silicon steel sheets.

[0006] The present application provides a cross-cutting system for cutting central column-shaped silicon steel sheets, which adopts the following technical solution:

[0007] A cross-cutting system for cutting column-shaped silicon steel sheets includes an unwinding machine and a frame disposed on one side of the unwinding machine. The frame is equipped with a conveyor for conveying silicon steel strip. A first V-shaped punch, two sets of punching knives, and a second V-shaped punch are sequentially arranged on the frame along the conveying direction of the conveyor. Several sets of conveyor are arranged along the length of the frame, and gaps are reserved between adjacent conveyor for waste material to fall. The frame is equipped with a lifting assembly for driving the first V-shaped punch, the two sets of punching knives, and the second V-shaped punch toward or away from the silicon steel strip. A collection assembly for collecting finished silicon steel sheets is disposed at the end of the frame away from the unwinding machine.

[0008] By adopting the above technical solution, the lifting assembly drives the first V-shaped punch, two sets of punching blades, and the second V-shaped punch to simultaneously cut the silicon steel strip on the frame, thus obtaining a complete silicon steel sheet. This reduces the downtime of the unwinding machine and the conveyor, thereby improving the cutting efficiency of the silicon steel sheet. During the transportation of the cut waste material through the conveyor, the waste material falls through the gap between adjacent conveyors due to its own weight, separating the waste material from the finished silicon steel sheet. Finally, the collection assembly quickly collects the finished silicon steel sheet, thereby improving the overall cutting efficiency of the silicon steel sheet.

[0009] Preferably, the lifting assembly includes a mounting frame, a lifting component, a lifting rod, and a connecting rod; the mounting frame is disposed on the top of the frame, the lifting component is disposed on the mounting frame, the lifting rod is disposed at the output end of the lifting component, and the lifting component is used to drive the lifting rod closer to or away from the silicon steel strip; the connecting rod is disposed on the side wall of the first V-punch, the two sets of punching knives, and the second V-punch facing the lifting rod, and each of the connecting rods is connected to the lifting rod.

[0010] By adopting the above technical solution, the output end of the lifting component performs telescopic movement, so that the lifting rod drives the connecting rod to move up and down, thereby driving the first V-punch, the two sets of punching knives and the second V-punch to move closer to or away from the frame, thus realizing the synchronous cutting of silicon steel strip by driving the first V-punch, the two sets of punching knives and the second V-punch, and improving the cutting efficiency of silicon steel sheet.

[0011] Preferably, the length direction of the lifting rod is parallel to the conveying direction of the conveying component, and each of the connecting rods can slide along the length direction of the lifting rod.

[0012] By adopting the above technical solution, the distance between adjacent first V-punches, two sets of punching knives and second V-punches can be adjusted by sliding the connecting rod along the length of the lifting rod, so as to cut silicon steel sheets of different lengths and sizes, thereby improving the applicability of the cutting system.

[0013] Preferably, the collecting assembly includes a collecting platform, a positioning frame, a pushing component, a mounting plate, and a flexible block; the collecting platform is located at the end of the frame away from the unwinding machine, the positioning frame is located on the collecting platform, the pushing component is located on the positioning frame, and the mounting plate is located at the output end of the pushing component. The pushing component is used to drive the mounting plate closer to or away from the collecting platform; the flexible block is located on the side wall of the mounting plate facing the collecting platform to press the finished silicon steel sheet onto the collecting platform.

[0014] By adopting the above technical solution, when the conveyor transports the finished silicon steel sheet away from the frame, the extension of the output end of the pusher drives the mounting plate to move the flexible block closer to the collection platform, thereby pressing and fixing the finished silicon steel sheet output by the conveyor onto the collection platform, so as to achieve rapid collection of the finished silicon steel sheet.

[0015] Preferably, the material collection platform has a through-hole for the silicon steel sheet finished product to fall, and a material collection plate is provided below the through-hole on the material collection platform. The material collection plate is provided with a stacking rod for passing through the silicon steel sheet finished product. A bearing plate for supporting the silicon steel sheet finished product is rotatably provided inside the through-hole, and a support component for supporting the bearing plate is provided inside the material collection platform.

[0016] By adopting the above technical solution, the support component supports the carrier plate, so that the carrier plate and the collection component can cooperate with each other to realize the rapid collection of silicon steel sheet products. When the support component is removed from supporting the carrier plate, the carrier plate rotates under its own weight and is no longer supporting the silicon steel sheet products. The silicon steel sheet products fall due to gravity and are fitted onto the stacking rod. The stacking rod passes through the round hole on the silicon steel sheet product, realizing the rapid stacking and collection of silicon steel sheet products. This reduces the phenomenon of excessive accumulation of silicon steel sheet products on the collection platform, which makes it difficult for the flexible block to press new silicon steel sheet products.

[0017] Preferably, the support assembly includes a support plate, an elastic element, a traction rope, and a guide wheel; the inner wall of the passageway has an installation groove, the support plate is slidably disposed inside the installation groove, and the support plate can abut against the bottom of the bearing plate; the elastic element is disposed between the inner wall of the installation groove and the support plate to drive the support plate to slide towards the bearing plate; the side wall of the collection platform has a through-hole communicating with the inside of the installation groove, the traction rope passes through the through-hole, one end of the traction rope is connected to the support plate, and the other end of the traction rope is connected to the installation plate; and when the installation plate moves away from the collection platform, the traction rope pulls the support plate away from the bearing plate; the guide wheel is rotatably disposed inside the through-hole, and the traction rope abuts against the peripheral wall of the guide wheel.

[0018] By adopting the above technical solution, when the output end of the pusher drives the mounting plate and the flexible block closer to the carrier plate, the traction force of the mounting block on the support plate through the traction rope gradually decreases, causing the elastic element to drive the support plate to move closer to the carrier plate through its own elastic force, so as to support the carrier plate and facilitate the collection of silicon steel sheet products by the carrier plate and the flexible block. When the output end of the pusher drives the mounting plate away from the carrier plate, the mounting plate applies traction force to the support plate through the traction rope, so that the support plate gradually slides into the mounting groove and detaches from the support plate. The carrier plate rotates under its own weight, so that the silicon steel sheet products fall through the passage. This realizes the driving of the support component by the movement of the pusher, reduces the need for a separate power source for the support component, and realizes the mechanical linkage between the collection component and the support component.

[0019] Preferably, each of the punching cutters is provided with a punching platform below it, and the punching cutter is provided with a material removal component for driving the waste material away from the punching platform; a pressure platform is provided below the second V-punch, and the second V-punch is provided with a pressing component for pressing the end of the silicon steel strip away from the unwinding machine, and a material removal component for driving the waste material away from the pressure platform is also provided on the pressure platform.

[0020] By adopting the above technical solution, the punching table and punching knife work together, and the stripping component drives the round waste material to detach from the silicon steel strip; the pressure table and the second V-punch work together, and the pressing component assists in pressing the end of the silicon steel strip away from the unwinding machine, reducing the phenomenon of the silicon steel strip end curling up and affecting the cutting quality of silicon steel sheets; and the detachment component drives the waste material to detach from the pressure table, realizing the separation of waste material from finished silicon steel sheets and improving the collection efficiency of finished silicon steel sheets.

[0021] Preferably, the stripping assembly includes a fixed plate, a sliding rod, an anti-slip block, a reset component, and a stripping rod; the fixed plate is disposed between the punching cutter and the corresponding connecting rod; the sliding rod is disposed on the side wall of the fixed plate facing the punching cutter; the punching cutter has a sliding groove for the sliding rod to slide into; the anti-slip block is disposed at the end of the sliding rod facing the punching cutter; the inner side wall of the sliding groove has an anti-slip groove for the anti-slip block to slide in; the reset component is disposed between the fixed plate and the punching cutter to drive the punching cutter to reset; the stripping rod is disposed on the side wall of the fixed plate facing the punching cutter; a stripping port is provided through the punching platform for the stripping rod to slide into; the inner side wall of the stripping port has an expansion notch to facilitate the stripping of waste material.

[0022] By adopting the above technical solution, when the lifting component drives the punching cutter to abut the punching table, the punching cutter, in conjunction with the punching table, cuts the silicon steel strip. During this process, the resetting component deforms and contracts under pressure. The elastic force of the resetting component on the punching cutter ensures the cutting action of the punching cutter on the silicon steel strip and causes the sliding rod to slide relative to the punching cutter, thereby shortening the overall length of the punching cutter and the sliding rod. The output end of the lifting component continues to extend, causing the stripping rod to gradually approach the punching table and push the round waste material cut on the punching table into the expansion notch for discharge. When the lifting component drives the punching cutter away from the punching table, the resetting component deforms and recovers, and in conjunction with the weight of the punching cutter, drives the punching cutter to slide relative to the sliding rod, thereby achieving the resetting of the punching cutter.

[0023] Preferably, the pressing assembly includes a connecting plate, a guide rod, a pressing block, and a telescopic member; the connecting plate is disposed on the connecting rod corresponding to the second V-shaped punch, the guide rod passes through the connecting plate, the pressing block is disposed at the end of the guide rod facing the pressure table, and the distance between the pressing block and the pressure table is less than the distance between the second V-shaped punch and the pressure table; the telescopic member is disposed between the connecting plate and the pressing block to drive the pressing block closer to the pressure table.

[0024] By adopting the above technical solution, during the process of the lifting component driving the second V-shaped punch to approach the silicon steel strip on the pressure platform, the connecting plate drives the pressing block to first abut against the pressure platform to press the silicon steel strip on the pressure platform, thereby facilitating the subsequent cutting work; after the pressing block abuts against the pressure platform, the telescopic component deforms and contracts under pressure, ensuring the stable pressing work of the pressing block on the silicon steel strip on the pressure platform, and allowing the second V-shaped punch to continue to descend.

[0025] Preferably, the detachment assembly includes two sets of support wing plates, a drive component, a dividing cutter, two sets of sliding blocks, two sets of first connecting rods, and two sets of second connecting rods; the top wall of the pressure platform has an installation notch, and both support wing plates are rotatably mounted on the top of the installation notch to bear waste material, and both sets of support wing plates are symmetrically distributed along the central axis of the second V-shaped punch; the drive component is disposed inside the installation notch, the dividing cutter is disposed at the output end of the drive component, and a gap is left between the two support wing plates for the dividing cutter to pass through, and the drive component is used to drive the dividing cutter to move closer to or away from the pressing assembly;

[0026] The supporting wing plate, sliding block, first connecting rod and second connecting rod are respectively arranged accordingly. Both sliding blocks are slidably arranged inside the mounting notch, and both sliding blocks are symmetrical about each other in the extension and retraction direction of the output end of the driving component. One end of each first connecting rod is rotatably connected to the corresponding supporting wing plate, and the other end of the first connecting rod is rotatably connected to the corresponding sliding block. One end of each second connecting rod is rotatably connected to the corresponding sliding block, and the other end of each second connecting rod is rotatably connected to the dividing tool.

[0027] By adopting the above technical solution, when the output end of the driving component drives the dividing cutter away from the pressing assembly, the dividing cutter drives the two sets of sliding blocks to move away from the driving component through the second connecting rod. The sliding blocks drive the first connecting rod to support the supporting wing plate, so that the supporting wing plate supports the silicon steel strip on the upper surface of the pressure plate, so as to cooperate with the pressing assembly to press the end of the silicon steel strip.

[0028] When the output end of the drive unit drives the dividing cutter to approach the pressing assembly, the dividing cutter can cut and divide the waste material. In addition, the dividing cutter pulls two sets of sliding blocks closer to each other through the second link. The sliding blocks pull the support wing plate to rotate toward the inside of the mounting notch through the first link, so that the support wing plate tilts, so that the waste material can be quickly detached from the pressure block through the support wing plate, thereby realizing the linkage of cutting and unloading the waste material.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. By setting up a lifting assembly to drive the first V-shaped punch, two sets of punching blades, and the second V-shaped punch to simultaneously cut the silicon steel strip on the frame, a complete silicon steel sheet can be obtained, reducing the downtime of the unwinding machine and conveyor, thereby improving the cutting efficiency of silicon steel sheets; the cut waste material, under its own weight, falls through the gap between adjacent conveyor components, separating the waste material from the finished silicon steel sheet; finally, the collection assembly quickly collects the finished silicon steel sheet, thereby improving the overall cutting efficiency of silicon steel sheets;

[0031] 2. By setting up a pressing component to assist in pressing the end of the silicon steel strip away from the unwinding machine, the phenomenon of the silicon steel strip end curling up and affecting the cutting quality of silicon steel sheets is reduced; a material removal component is set up to drive the round waste material away from the silicon steel strip; and the material removal component is used to drive the waste material away from the pressure table, thereby realizing the separation of waste material from finished silicon steel sheets and improving the collection efficiency of finished silicon steel sheets.

[0040] The following is in conjunction with the appendix Figure 2-6 This application will be described in further detail.

[0041] This application discloses a cross-cutting system for cutting central column-shaped silicon steel sheets, which is used to classify and collect finished silicon steel sheets and cutting waste.

[0042] Reference Figure 2 and Figure 3A cross-cutting system for cutting silicon steel sheets of the central column type includes an unwinding machine 1 placed on the ground. A frame 3 is installed on the ground on one side of the unwinding machine 1. Several sets of conveyor components 31 are installed on the frame 3. All conveyor components 31 are spaced apart along the length of the frame 3, and gaps are left between adjacent conveyor components 31 for waste material to fall. In this embodiment, the conveyor component 31 can be a belt conveyor for conveying the silicon steel strip unwound by the unwinding machine 1.

[0043] Reference Figure 2 and Figure 3 The frame 3 is equipped with a first V-shaped punch 21, two sets of punching knives 22 and a second V-shaped punch 23. In this embodiment, the opening directions of the first V-shaped punch 21 and the second V-shaped punch 23 are opposite; and the first V-shaped punch 21, the two sets of punching knives 22 and the second V-shaped punch 23 are all arranged sequentially along the conveying direction of the conveyor 31.

[0044] Reference Figure 2 and Figure 3 A lifting assembly 4 is installed on the frame 3 to drive the first V-brush 21, two sets of punching blades 22, and the second V-brush 23 to move up and down, thereby cutting the silicon steel strip. The lifting assembly 4 includes a mounting frame 41, a lifting component 42, a lifting rod 43, and a connecting rod 44. In this embodiment, the lifting component 42 can be a lifting cylinder. The mounting frame 41 is welded and fixed to the top of the frame 3, and the lifting component 42 is fixedly connected to the side wall of the mounting frame 41 facing the frame 3, with the extension and retraction direction of the output end of the lifting component 42 parallel to the vertical direction.

[0045] Reference Figure 2 and Figure 3 The lifting rod 43 is welded and fixed to the output end of the lifting component 42, and the length direction of the lifting rod 43 is parallel to the conveying direction of the conveying component 31. Connecting rods 44 are installed on the sidewalls of the first V-shaped punch 21, the two sets of punching knives 22, and the second V-shaped punch 23 facing the lifting rod 43. Each set of connecting rods 44 is slidably connected to the lifting rod 43, and each set of connecting rods 44 slides along the length direction of the lifting rod 43. Each set of connecting rods 44 and the lifting rod 43 are connected by a fixing bolt, and the lifting rod 43 has several sets of threaded holes along its length for the fixing bolts to be inserted, so as to adjust the distance between adjacent first V-shaped punches 21, punching knives 22, and second V-shaped punches 23.

[0046] Reference Figure 2 and Figure 3 By extending and retracting the output end of the lifting component 42, the lifting rod 43 can drive the first V-punch 21, the two sets of punching knives 22 and the second V-punch 23 to move up and down synchronously, thereby cutting the silicon steel strip synchronously and cutting it into a finished silicon steel sheet in one go.

[0047] Reference Figure 2 and Figure 3 A punching table 32 is installed on the frame 3 directly below each set of punching blades 22 to cut the silicon steel strip in conjunction with the punching blades 22; a receiving table 30 is installed on the frame 3 directly below the first V-shaped punch 21 to cut in conjunction with the first V-shaped punch 21; and a pressure table 33 is installed on the frame 3 directly below the second V-shaped punch 23 to cut the silicon steel strip in conjunction with the second V-shaped punch 23. In this embodiment, the punching table 32, the receiving table 30, and the pressure table 33 are all spaced apart from each other, and at least one set of conveying components 31 is installed between any two adjacent sets.

[0048] Reference Figure 2 and Figure 3 In this embodiment, mounting wing plates are welded and fixed to the side walls of the punching platform 32, receiving platform 30, and pressure platform 33 facing the frame 3. The inner wall of the frame 3 has a sliding groove for the mounting wing plates to abut against, and mounting bolts are inserted into both the frame 3 and each set of mounting wing plates. The frame 3 has several sets of bolt holes along its length for the mounting bolts to pass through, and all bolt holes correspond one-to-one with the threaded holes on the lifting rod 43, facilitating synchronous position adjustment of the first V-brush 21, punching blade 22, second V-brush 23 with the corresponding receiving platform 30, punching platform 32, and pressure platform 33.

[0049] Reference Figure 3 and Figure 4 Each set of punching cutters 22 is equipped with a stripping assembly 7 to drive the cut circular waste material out of the punching table 32. The stripping assembly 7 includes a fixing plate 71, a sliding rod 72, an anti-slip block 73, a reset member 74, and a stripping rod 75. In this embodiment, the reset member 74 can be a reset spring. The fixing plate 71 is located between each set of punching cutters 22 and the corresponding connecting rod 44, and the side wall of the fixing plate 71 facing away from the punching cutter 22 is welded and fixed to the corresponding connecting rod 44.

[0050] Reference Figure 3 and Figure 4 The sliding rod 72 is welded and fixed to the side wall of the fixing plate 71 facing the punching cutter 22. The side wall of the punching cutter 22 facing the fixed rod has a sliding groove 221, allowing the sliding rod 72 to slide into the sliding groove 221 along its length. The length of the sliding groove 221 is parallel to the extension / retraction direction of the output end of the lifting component 42. The anti-detachment block 73 is welded and fixed to the end of the sliding rod 72 located inside the sliding groove 221. The inner side wall of the sliding groove 221 has an anti-detachment groove 222, allowing the anti-detachment block 73 to slide along its length. The side wall of the anti-detachment block 73 facing the fixing plate 71 can abut against the inner side wall of the anti-detachment groove 222, thereby preventing the sliding rod 72 from disengaging from the sliding groove 221.

[0051] Reference Figure 3 and Figure 4 The reset component 74 is sleeved on each set of sliding rods 72, and one end of each set of reset components 74 is glued to the fixing plate 71, and the other end of each set of reset components 74 is glued to the punching knife 22. The stripping rod 75 is welded and fixed to the side wall of the fixing plate 71 facing the punching knife 22, and the stripping rod 75 passes through the punching knife 22; and when the punching knife 22 is not in contact with the punching table 32, the distance between the punching table 32 and the punching table 32 is greater than the distance between the stripping rod 75 and the punching table 32. The punching table 32 has a stripping port 321 through which the stripping rod 75 abuts. The inner side wall of the stripping port 321 has an expansion notch 322, which is connected to the end of the punching table 32 away from the punching knife 22, and the inner diameter of the expansion notch 322 is larger than the diameter of the circular waste, so that the waste can pass through the expansion notch 322 and get off the punching table 32.

[0052] Reference Figure 3 and Figure 4 When the lifting member 42 drives the punching cutter 22 to abut against the punching table 32, the punching cutter 22 works with the punching table 32 to cut the silicon steel strip. Simultaneously, the resetting member 74 deforms and contracts under pressure, and the sliding rod 72 slides relative to the punching cutter 22, shortening the overall length of the punching cutter 22 and the sliding rod 72. This causes the stripping rod 75 to gradually approach the punching table 32, pushing the circular waste material on the punching table 32 into the expansion notch 322 for discharge. When the lifting member 42 drives the punching cutter 22 away from the punching table 32, the resetting member 74 deforms and recovers, and with the weight of the punching cutter 22, drives the punching cutter 22 to slide relative to the sliding rod 72, thereby resetting the punching cutter 22.

[0053] Reference Figure 3 and Figure 5 A pressing assembly 8 is installed on the second V-punch 23 to press the end of the silicon steel strip away from the unwinding machine 1 onto the pressure table 33. The pressing assembly 8 includes a connecting plate 81, a guide rod 82, a pressing block 83, and a telescopic member 84. In this embodiment, the telescopic member 84 can be a telescopic spring. The connecting plate 81 is welded and fixed to the connecting rod 44 corresponding to the second V-punch 23, and the connecting plate 81 is located on the side of the second V-punch 23 away from the punching knife 22. The guide rod 82 passes through the connecting plate 81, and the pressing block 83 is fixedly connected to the end of the guide rod 82 facing the pressure table 33. The distance between the pressing block 83 and the upper surface of the pressure table 33 is smaller than the distance between the second V-punch 23 and the upper surface of the pressure table 33. This allows the pressing block 83 to abut against the silicon steel strip on the pressure table 33 before the second V-punch 23 moves towards the pressure table 33 when the lifting member 42 drives the second V-punch 23 and the pressing block 83.

[0054] Reference Figure 3 and Figure 5The telescopic components 84 are all sleeved on each set of guide rods 82, and one end of the telescopic component 84 along its length is glued to the side wall of the connecting rod 44 facing the pressing block 83, and the other end of the telescopic component 84 is glued to the side wall of the pressing block 83 facing the connecting plate 81, so that the pressing block 83 abuts against the pressure table 33. The telescopic component 84 can deform and shrink, so that the telescopic component 84 drives the pressing block 83 to stably press the silicon steel strip against the pressure table 33 through its own elasticity.

[0055] Reference Figure 3 and Figure 5 A release assembly 9 is installed on the pressure platform 33 to drive the waste material on the pressure platform 33 to detach from the pressure platform 33. The release assembly 9 includes two sets of support wing plates 91, a drive component 92, a dividing cutter 93, two sets of sliding blocks 94, two sets of first connecting rods 95 and two sets of second connecting rods 96; in this embodiment, the drive component 92 may be a drive cylinder.

[0056] Reference Figure 3 and Figure 5 The top wall of the pressure platform 33 has an installation notch 331. The drive component 92 is fixedly installed on the bottom wall of the installation notch 331, and the drive component 92 is located in the middle of the installation notch 331. The dividing cutter 93 is fixedly installed on the output end of the drive component 92, so that it can extend and retract through the output end of the drive component 92, thereby making the dividing cutter 93 approach or move away from the pressing block 83, so as to cut and divide the waste material pressed by the pressing block 83.

[0057] Reference Figure 3 and Figure 5 Both sets of support wing plates 91 are rotatably connected to the top of the mounting notch 331 via a pivot, and both sets of support wing plates 91 are symmetrically distributed along the central axis of the second V-shaped punch 23, with a gap between the two sets of support wing plates 91 for the cutting tool 93 to pass through. The sidewalls of the two sets of support wing plates 91 facing the pressing block 83 are coplanar with the top wall of the pressure table 33 to support the silicon steel strip on the top of the pressure block, thereby cooperating with the pressing block 83 to press the silicon steel strip.

[0058] Reference Figure 3 and Figure 5The supporting wing plate 91, sliding block 94, first connecting rod 95, and second connecting rod 96 are respectively and correspondingly arranged, and are symmetrically distributed on both sides of the driving member 92. Both sets of sliding blocks 94 are slidably connected to the inner sidewalls of the mounting notches 331 on both sides of the driving member 92. In this embodiment, the sliding block 94 can be a wedge-shaped block. One end of each set of first connecting rods 95 is rotatably connected to the bottom wall of the corresponding supporting wing plate 91, and the other end of each set of first connecting rods 95 is rotatably connected to the corresponding sliding block 94. One end of each set of second connecting rods 96 is rotatably connected to the corresponding sliding block 94, and the other end of each set of second connecting rods 96 is rotatably connected to the corresponding dividing cutter 93.

[0059] Reference Figure 3 and Figure 5 When the output end of the drive unit 92 drives the dividing cutter 93 away from the pressing block 83, the dividing cutter 93 drives the two sets of sliding blocks 94 to move away from the drive unit 92 through the second connecting rod 96. The sliding blocks 94 drive the first connecting rod 95 to support the support wing plate 91, so that the support wing plate 91 supports the silicon steel strip on the upper surface of the pressure table 33.

[0060] Reference Figure 3 and Figure 5 When the output end of the drive unit 92 drives the dividing cutter 93 to approach the pressing block 83 and cut the waste material, the dividing cutter 93 pulls the two sets of sliding blocks 94 closer to each other through the second link 96. The sliding block 94 pulls the support wing plate 91 toward the inside of the mounting notch 331 through the first link 95 so that the inclined support wing plate 91 can guide the waste material away from the pressure block.

[0061] Reference Figure 2 and Figure 6 A collection assembly 5 is installed at the end of the frame 3 furthest from the unwinder 1 to quickly collect finished silicon steel sheets. The collection assembly 5 includes a collection platform 51, a positioning frame 52, a pusher 53, a mounting plate 54, and a flexible block 55. In this embodiment, the pusher 53 can be a push cylinder, and the flexible block 55 can be made of soft rubber. The collection platform 51 is placed on the ground at the end of the frame 3 furthest from the unwinder 1. The positioning frame 52 is welded and fixed to the top wall of the collection platform 51, and the pusher 53 is welded and fixed to the positioning frame 52. The extension and retraction direction of the output end of the pusher 53 is parallel to the vertical direction.

[0062] Reference Figure 2 and Figure 6The mounting plate 54 is fixedly connected to the output end of the pusher 53, and the flexible block 55 is glued to the side wall of the mounting plate 54 facing the collection platform 51. By extending and retracting the output end of the pusher 53, the mounting plate 54 drives the flexible block 55 to move closer to or away from the collection platform 51, thereby pressing and fixing the finished silicon steel sheet output by the conveyor 31 onto the collection platform 51.

[0063] Reference Figure 2 and Figure 6 The top wall of the collecting platform 51 has a passage opening 511 for finished silicon steel sheets to pass through. A collecting plate 512 is placed on the ground below the passage opening 511. Two sets of stacking rods 513 are welded and fixed on the collecting plate 512 to pass through the fallen finished silicon steel sheets, thereby realizing the stacking of finished silicon steel sheets.

[0064] Reference Figure 2 and Figure 6 Inside the passageway 511, two sets of bearing plates 514 are rotatably installed. The side wall of each bearing plate 514 is coplanar with the top wall of the collecting platform 51 to support the finished silicon steel sheets. Inside the collecting platform 51, two sets of support components 6 are installed. The support components 6 are arranged one-to-one with the bearing plates 514 to support the bearing plates 514.

[0065] Reference Figure 2 and Figure 6 The support assembly 6 includes a support plate 61, an elastic element 62, a traction rope 63, and a guide wheel 64; an installation groove 515 is provided on the inner side wall of the passage 511 and below the bearing plate 514. The support plate 61 is slidably connected to the inside of the installation groove 515 along the length direction of the installation groove 515, and the support plate 61 can abut against the bottom wall of the bearing plate 514, thereby supporting the bearing plate 514.

[0066] Reference Figure 2 and Figure 6 Specifically, the elastic element 62 can be a spring. The elastic element 62 is glued between the support plate 61 and the bottom wall of the mounting groove 515, and the extension and contraction direction of the elastic element 62 is parallel to the length direction of the mounting groove 515, so that the support plate 61 can slide towards the bearing plate 514 by the elastic force of the elastic element 62 itself.

[0067] Reference Figure 2 and Figure 6The top wall of the collecting platform 51 has a connecting opening 516 for connecting to the interior of the mounting groove 515, and the connecting opening 516 is located on the side of the support plate 61 facing the elastic member 62. A traction rope 63 is inserted inside the connecting opening 516, with one end of the traction rope 63 glued to the side wall of the support plate 61 facing the elastic member 62, and the other end glued to the mounting plate 54. A guide wheel 64 is rotatably connected to the interior of the connecting opening 516 via a rotating shaft. The guide wheel 64 is located between the traction rope 63 and the support plate 61, and the traction rope 63 abuts against the peripheral wall of the guide wheel 64, thereby reducing the friction between the traction rope 63 and the inner side wall of the connecting opening 516.

[0068] Reference Figure 2 and Figure 6 When the output end of the pusher 53 drives the mounting plate 54 and the flexible block 55 closer to the bearing plate 514, the traction force of the mounting plate 54 and the traction rope 63 on the support plate 61 gradually decreases, so that the elastic member 62 pushes the support plate 61 to slide, gradually approaching the bearing plate 514 and supporting the bearing plate 514, thereby realizing the pressing and fixing of the silicon steel sheet product by the flexible block 55 and the bearing plate 514. When the output end of the pusher 53 drives the mounting plate 54 away from the bearing plate 514, the mounting plate 54 applies traction force to the traction rope 63 and the support plate 61, so that the support plate 61 gradually slides into the mounting groove 515 and causes the support plate 61 to detach from the support of the bearing plate 514. The bearing plate 514 rotates under its own weight, so that the silicon steel sheet product falls through the passage 511.

[0069] The implementation principle of a cross-cutting system for cutting central column-shaped silicon steel sheets according to an embodiment of this application is as follows:

[0070] The unwinding machine 1 unwinds the silicon steel strip, and the conveyor 31 conveys the silicon steel strip. During this process, the output end of the lifting component 42 drives the lifting rod 43 and the connecting rod 44 to approach the frame 3, so that the first V-punch 21, the two sets of punching knives 22 and the second V-punch 23 can simultaneously cut the silicon steel strip, thereby cutting and forming a complete silicon steel sheet.

[0071] During the cutting process of the punching knife 22, the stripping component 7 drives the circular waste material through the stripping port 321 of the punching table 32, thus achieving the separation of the circular waste material. During the cutting process of the second V-punch 23, the pressing component 8 presses the end of the silicon steel strip away from the unwinding machine 1, and the separation component 9 drives the waste material to detach from the pressure table 33, thereby achieving the rapid separation of the cut waste material from the silicon steel strip.

[0072] Finally, the pusher 53 drives the mounting plate 54 and the flexible block 55 to press the finished silicon steel sheet against the bearing plate 514. Then, the bearing plate 514 removes its support for the finished silicon steel sheet, allowing it to fall onto the collecting plate 512. This achieves rapid collection of the finished silicon steel sheet and improves the cutting efficiency of the silicon steel sheet.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
