Description

Technical Field

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

[0002] Silicon steel sheets are an essential soft magnetic alloy for the electronics, power, and military industries. They are commonly used as the cores of various motors, generators, and transformers. Among them, silicon steel sheets used to assemble transformer cores include edge-pillar type silicon steel sheets. This type of silicon steel sheet is trapezoidal with two through holes on its surface and is usually produced using a cross-shearing system.

[0003] In related technologies, a side-post type silicon steel sheet shearing production line is provided, which includes a cross-cutting line mounting frame, a 135° skewer, a 45° skewer, and a fixed punching machine mounted on the cross-cutting line mounting frame. The 135° skewer and 45° skewer are located downstream of the production line, while the fixed punching machine is located upstream. Two fixed punching machines are distributed along the feeding direction of the production line. During the silicon steel sheet shearing process, the silicon steel sheet roll is conveyed on the production line, first passing through the fixed punching machine for punching, and then moving to the 135° skewer and 45° skewer for edge trimming, ultimately obtaining the desired silicon steel sheet.

[0004] Regarding the aforementioned technologies, the inventors discovered that during the punching and cutting of silicon steel sheets, the silicon steel sheets are stopped from being transported on the production line for punching or cutting. However, in the aforementioned technologies, punching and cutting are not performed synchronously, which requires multiple stops of transport during the cutting of the same silicon steel sheet. This setup reduces cutting efficiency and therefore needs improvement. Summary of the Invention

[0005] To improve the cutting efficiency of silicon steel sheets, this application provides a cross-cutting system for cutting edge column type silicon steel sheets.

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

[0007] A cross-cutting system for cutting edge-column type silicon steel sheets includes a frame and a conveyor frame. The conveyor frame is used to transfer silicon steel sheets to the frame. A conveying track is provided on the surface of the frame along its length. The conveying track is connected to the conveyor frame. A guide wheel is provided at one end of the conveying track near the conveyor frame. The guide wheel is used to drive the silicon steel sheets to move on the conveying track. Two sets of oblique shearing devices are provided on the conveying track. Both sets of oblique shearing devices are located on the side of the guide wheel away from the conveyor frame. A punching device is provided between the two sets of oblique shearing devices. The punching device includes two punching stations distributed along the length of the conveying track.

[0008] By adopting the above technical solution, the silicon steel sheet strip will be conveyed to the frame by the conveyor frame and move along the length of the conveyor track under the action of the guide wheel. When the silicon steel sheet is in place, the oblique shearing device and the punching device are activated at the same time. This allows for the cutting of both sides of the silicon steel sheet while punching holes on the surface of the silicon steel sheet. This improves the problem in the existing technology that the cutting process of a single silicon steel sheet requires multiple stops of the silicon steel sheet transportation for punching and cutting, resulting in low efficiency and long time consumption. This application can form a complete silicon steel sheet in one cut in the same process, improving the efficiency of cutting and production, and has high convenience and economic benefits.

[0009] Preferably, the conveying track includes two parallel support rails, and the frame is provided with an adjustment component, which is used to adjust the distance between the two support rails according to the width of the silicon steel sheet.

[0010] By adopting the above technical solution, the conveying track is set as two parallel support rails, and an adjustment component is set to adjust the distance between the two support rails, so that the cross-cutting system of this application can be applied to the cutting of silicon steel sheets of different widths, thereby improving the applicability and practicality of the cross-cutting system of this application.

[0011] Preferably, the adjustment assembly includes an adjustment track, a drive component, an adjustment screw, and two adjustment blocks, with each adjustment block corresponding to a support guide rail. The adjustment track is disposed on the surface of the frame and is perpendicular to the support guide rail. Both adjustment blocks are slidably connected to the adjustment track, with the end of each adjustment block facing away from the adjustment track connected to the bottom wall of the corresponding support guide rail. The adjustment screw is disposed parallel to the adjustment track and has two threaded sections in opposite directions. The adjustment screw passes through the two adjustment blocks sequentially and is threadedly connected to them. Each adjustment block corresponds to one threaded section. The drive component is disposed on the surface of the frame, and its output end is connected to the adjustment screw. The adjustment screw drives the two adjustment blocks to move closer or further apart.

[0012] By adopting the above technical solution, the driving component is activated, which drives the adjusting screw to rotate. Then, by adjusting the two opposite threaded sections on the screw, the two adjusting blocks move towards or away from each other, thus adjusting the distance between the two support rails. The adjustment component of this application has a simple structure, is easy to implement, and has high automation performance. When the width of the silicon steel sheet is small, the two support rails move closer together; when the width of the silicon steel sheet is large, the two support rails move further apart, flexibly adjusting the distance to adapt to the cross-cutting work of silicon steel sheets of different sizes and models, thus improving the applicability of the cross-cutting system of this application.

[0013] Preferably, the frame surface is provided with a moving track, the length direction of the moving track is consistent with the length direction of the conveying track, two adjusting plates are slidably connected on the moving track, the adjusting plates correspond one-to-one with the punching station, the adjusting plates are provided with a feed track, the feed track is set perpendicular to the moving track, and the punching station is slidably connected to the feed track.

[0014] By adopting the above technical solution, the positions of the two punching stations can be adjusted by setting the moving track and the feed track to meet the requirements of punching holes at different positions on the silicon steel sheet. This allows the cross-cutting system of this application to cut silicon steel sheets of different specifications and types. It has a high degree of automation and can effectively improve cutting efficiency and economic benefits.

[0015] Preferably, the oblique shearing device includes a support platform, a lifting platform, a lifting component, and a cutting blade. The support platform is disposed on the surface of the frame and is used for the silicon steel sheet to abut against. The lifting platform is disposed above the support platform, and the lifting component is connected to the lifting platform. The lifting component drives the lifting platform to rise or fall relative to the support platform. A buffer groove is formed in the bottom wall of the lifting platform, and the cutting blade is connected to the bottom wall of the buffer groove. A blade insertion groove is formed on the surface of the support platform for the cutting blade to be inserted. A buffer block is slidably connected in the buffer groove, and a buffer component is provided in the bottom wall of the buffer groove. The buffer component drives the buffer block to slide towards the support platform. A cutting through groove is formed along the thickness direction of the buffer block for the cutting blade to pass through.

[0016] By adopting the above technical solution, when the silicon steel sheet moves to the surface of the support platform for cross-cutting, the lifting mechanism will drive the lifting platform to descend towards the support platform. The abutment block will pre-abut against the silicon steel sheet on the surface of the support platform, so that when the cutting blade cuts the silicon steel sheet, the abutment block can improve the stability of the silicon steel sheet and improve the cross-cutting quality. As the lifting platform continues to descend, the buffer will be compressed, and the buffer block will gradually enter the buffer groove. At this time, the cutting blade will also pass through the cutting groove and cross-cut the silicon steel sheet. The degree of automation is high, which can effectively improve the cross-cutting effect.

[0017] Preferably, a discharge port is provided on the surface of the support platform away from the transmission wheel, and a drop groove is provided on the surface of the frame corresponding to the discharge port. Two opening and closing plates are provided at the discharge port, and a rotating shaft is provided on the surface of the opening and closing plates. The opening and closing plates are rotatably connected to the support platform through the rotating shaft. A drive assembly is provided on the frame, and the drive assembly is used to drive the two opening and closing plates to rotate in a direction that moves closer to each other or further away from each other.

[0018] By adopting the above technical solution, after the silicon steel sheet coil has undergone multiple cross-cuttings, due to the trapezoidal shape of the side column type silicon steel sheet, a portion of the silicon steel sheet coil will be left as waste. If the waste continues to be conveyed on the frame, it needs to be removed manually, which affects work efficiency. By opening a discharge port, the waste can be removed. After the drive component drives the opening and closing plate to rotate and expose the discharge port, the waste passing through the discharge port will enter the dropping chute, thereby realizing automated waste cleaning, which has high convenience and practicality.

[0019] Preferably, the drive assembly includes a drive cylinder, a connecting plate, two drive racks, and two drive gears, with the drive racks, drive gears, and opening / closing plate corresponding one-to-one; the drive cylinder is disposed on the bottom wall of the support platform, the connecting plate is connected to the piston rod of the drive cylinder, both drive racks are connected to the side of the connecting plate near the opening / closing plate, the drive gears are sleeved on the corresponding rotating shaft peripheral wall, the two drive gears are located between the two drive racks on both sides, and the drive gears mesh with the corresponding drive racks.

[0020] By adopting the above technical solution, the drive cylinder is started, which drives the connecting plate to move. Through the meshing relationship between the drive rack and the corresponding drive gear, the rotating shaft and the corresponding opening and closing plate are driven to rotate together. When the opening and closing plates on both sides rotate in opposite directions, the discharge port will be exposed. When the residual material passes through the discharge port, it loses the resistance of the opening and closing plate and falls into the discharge port and further enters the discharge trough, realizing automatic material discharge and further improving the working efficiency and convenience of the cross-cutting system of this application.

[0021] Preferably, the bottom wall of the support platform is provided with two guide plates, and the guide plates and the opening and closing plates correspond one to one. The surface of the opening and closing plates is provided with guide posts, and the surface of the guide plates is provided with limiting grooves for the guide posts to be inserted and slid. The limiting grooves are opened along the rotation direction of the guide posts.

[0022] By adopting the above technical solution, a guide plate is set and a limiting groove is opened on the guide plate. When the opening and closing plate rotates, the guide column also rotates in the limiting groove, thereby limiting the rotation stroke of the opening and closing plate and making the rotation of the opening and closing plate more stable.

[0023] Preferably, the opening and closing plate has a countersunk groove on its surface, and an abutment plate is slidably connected in the countersunk groove. An elastic element is provided in the countersunk groove, and the elastic element abuts between the bottom wall of the countersunk groove and the abutment plate. The elastic element drives the abutment plate to slide in a direction away from the frame. The abutment plate has a guide surface on its inner wall facing the discharge port. After the opening and closing plate rotates, the guide surface abuts against the inner wall of the discharge port, and the support platform pushes the abutment plate into the countersunk groove.

[0024] By adopting the above technical solution, when the two opening and closing plates are not rotated, the two opening and closing plates close the discharge port. The abutment plate, which has lost the support platform, will extend out of the countersunk groove under the abutment action of the elastic element, thereby maintaining the same height as the support platform surface. This allows the silicon steel sheet to pass smoothly through the discharge port, reducing the obstruction of the discharge port to the silicon steel sheet conveying and improving the smoothness of silicon steel sheet conveying. When the opening and closing plates rotate, the guide surface of the abutment block will abut against the inner wall of the discharge port, thereby pushing the abutment plate into the countersunk groove, which has high convenience.

[0025] Preferably, baffles are provided on the side walls of the two opening and closing plates that are close to each other.

[0026] By adopting the above technical solution, the baffle can limit the discharge of waste material. The baffle rotates together with the opening and closing plate, so that the waste material can accurately enter the discharge chute after entering the discharge port, thereby improving the efficiency and accuracy of discharge.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The silicon steel sheet strip will be conveyed to the frame by the conveyor frame and move along the length of the conveyor track under the action of the guide wheel. When the silicon steel sheet is in place, the oblique shearing device and the punching device are activated at the same time. This allows the silicon steel sheet to be cut on both sides and punched on the surface at the same time. This improves the problem that in the existing technology, the cutting process of a silicon steel sheet requires multiple stops of the silicon steel sheet to be transported for punching and cutting, which is inefficient and time-consuming. This application can form a complete silicon steel sheet in one cut in the same process, which improves the efficiency of cutting and production and has high convenience and economic benefits.

[0029] 2. After the silicon steel sheet coil undergoes multiple cross-cuttings, due to the trapezoidal shape of the edge-column type silicon steel sheet, some waste material will remain on the coil. If the waste material continues to be conveyed on the frame, it needs to be removed manually, affecting work efficiency. By opening a discharge port, the waste material can be removed. After the drive component drives the opening and closing plate to rotate and expose the discharge port, the waste material passing through the discharge port will enter the dropping chute, thereby realizing automated waste material cleaning, which has high convenience and practicality.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] This application discloses a cross-cutting system for cutting edge-column type silicon steel sheets. (Refer to...) Figure 1 It includes a rack 1 and a conveyor 2 that are interconnected. The conveyor 2 is connected to the entrance end of the rack 1, so that the silicon steel sheet can be conveyed toward the rack 1.

[0039] Reference Figure 1 and Figure 2The frame 1 has a conveyor track 3 on its surface, and the length direction of the conveyor track 3 is consistent with the length direction of the frame 1. The conveyor frame 2 transmits the silicon steel sheet to the conveyor track 3, and the conveyor track 3 drives the silicon steel sheet to be conveyed along the length direction of the frame 1. The conveyor track 3 includes two parallel support rails 32, both of which are set in the same horizontal plane. The support rails 32 are used to support the silicon steel sheet so that the silicon steel sheet can be stably conveyed on the support rails 32. The frame 1 has several sets of adjustment components 6 on its surface to adjust the distance between the two support rails 32 so that the support rails 32 can adapt to the conveying of silicon steel sheets of different widths. The several sets of adjustment components 6 are distributed along the length direction of the frame 1.

[0040] Reference Figure 1 and Figure 2 The adjustment assembly 6 includes an adjustment rail 61, a drive component 62, an adjustment screw 63, and two adjustment blocks 64. The adjustment blocks 64 and the support guide rails 32 are arranged in a one-to-one correspondence. The adjustment rail 61 is bolted to the surface of the frame 1. The length direction of the adjustment rail 61 is perpendicular to the length direction of the support guide rail 32. The two adjustment blocks 64 are slidably connected to the adjustment rail 61. The adjustment rail 61 can restrict the adjustment blocks 64, allowing the adjustment blocks 64 to slide along the length direction of the adjustment rail 61. The end of the adjustment block 64 facing away from the adjustment rail 61 is bolted to the bottom wall of the corresponding support guide rail 32. When the adjustment block 64 slides, it will drive the support guide rail 32 to slide together, thereby adjusting the distance between the two support guide rails 32.

[0041] Reference Figure 1 and Figure 2 The adjusting screw 63 is set parallel to the adjusting rail 61. Both ends of the adjusting rail 61 are equipped with fixing plates. The adjusting screw 63 is positioned between the fixing plates on both sides and is rotatably connected to the fixing plates. The adjusting screw 63 includes two threaded sections with opposite directions. Each threaded section corresponds to an adjusting block 64. The adjusting screw 63 passes through the two adjusting blocks 64 in sequence, forming a threaded connection between the threaded sections and the corresponding adjusting blocks 64. When the adjusting screw 63 rotates, it can drive the two adjusting blocks 64 to move closer to or further away from each other. The movement allows for flexible adjustment of the distance between the two support guide rails 32, accommodating the conveying of silicon steel sheets of different widths. The drive component 62 is disposed on the surface of the frame 1 and is used to drive the adjusting screw 63 to rotate. In this embodiment, the drive component 62 is a motor. To save operating costs, adjacent adjustment components 6 can share one drive component 62. A bevel gear is provided at the end of the adjusting screw 63, and transmission is carried out through a transmission rod with a bevel gear, so that a single drive component 62 can drive the adjusting screws 63 of two sets of adjustment components 6 to rotate synchronously.

[0042] Reference Figure 1 and Figure 2 The conveying track 3 also includes a set of transmission wheels 31. The transmission wheels 31 are located at one end of the support guide rail 32 near the conveyor frame 2. The transmission wheels 31 are located between the support guide rails 32 on both sides. The transmission wheels 31 are divided into upper and lower parts to further transmit the silicon steel sheets conveyed by the conveyor frame 2. The two transmission wheels 31 abut against the upper and lower surfaces of the silicon steel sheets respectively, so that the silicon steel sheets can move along the length direction of the support guide rail 32.

[0043] Reference Figure 1 and Figure 3 Two sets of oblique shearing devices 4 are installed on the conveyor track 3. Both sets of oblique shearing devices 4 are located on the side of the guide wheel 31 away from the conveyor frame 2. The two sets of oblique shearing devices 4 are distributed along the length direction of the frame 1. In this embodiment, the support guide rail 32 has corresponding notches for the oblique shearing devices 4 to be installed. The oblique shearing device 4 on the side closer to the guide wheel 31 is 45°, and the other oblique shearing device 4 is 135°, so as to cut the silicon steel sheet into an isosceles trapezoidal shape. A punching device 5 is provided between the two sets of oblique shearing devices 4. The support guide rail 32 has notches for the punching device 5 to be installed. The punching device 5 includes two punching stations 51, which are distributed along the length direction of the conveyor track 3. When the silicon steel sheet is moved into place on the conveyor track 3, the two sets of oblique shearing devices 4 and punching devices 5 are activated at the same time, so that the oblique shearing and punching can be completed at the same time in one cut, and the silicon steel sheet of the target shape can be formed in one step, thereby improving the cutting efficiency.

[0044] Reference Figure 1 and Figure 3 The oblique shearing device 4 includes a support platform 41, a lifting platform 42, a lifting component 43, and a cutting blade 44. The bottom wall of the support platform 41 is provided with several support legs, which are welded to the surface of the frame 1. The conveying track 3 is connected to the support platform 41. After the silicon steel sheet is transported from the conveying track 3 to the support platform 41, it will abut against the surface of the support platform 41. The lifting platform 42 is set above the support platform 41, and the lifting component 43 is connected to the lifting platform 42 to drive the lifting platform 42 to rise or fall relative to the support platform 41. In this embodiment, the oblique shearing device 4 is also provided with a fixing frame located above the lifting platform 42 to fix the lifting component 43. The lifting component 43 is a cylinder, and its piston rod is connected to the lifting platform 42 to drive the lifting platform 42 to rise or fall.

[0045] Reference Figure 1 and Figure 4 The bottom wall of the lifting platform 42 is provided with a buffer groove 421. One end of the cutting blade 44 is connected to the bottom wall of the buffer groove 421. The cutting edge of the cutting blade 44 is set towards the support platform 41. The surface of the support platform 41 is provided with a drop groove 411 for the cutting blade 44 to be inserted. When the cutting edge of the cutting blade 44 enters the drop groove 411, it will complete the horizontal cutting of the silicon steel sheet.

[0046] Reference Figure 3 and Figure 4 A buffer block 422 is slidably connected within the buffer groove 421. The buffer block 422 has a through-cutting groove 4221 along its thickness direction for the cutting blade 44 to pass through. Several buffer elements 423 are provided on the bottom wall of the buffer groove 421. In this embodiment, the buffer element 423 is a combination of a guide rod and a spring. The guide rod is vertically arranged, with one end inserted into the buffer block 422, allowing the buffer block 422 to slide along the length of the guide rod. The spring is sleeved on the periphery of the guide rod, with one end glued to the bottom wall of the buffer groove 421 and the other end glued to the buffer block. Connected to 422, the buffer element 423 drives the buffer block 422 to slide towards the support platform 41. When the lifting platform 42 slides towards the support platform 41, the buffer block 422 will abut against the silicon steel sheet on the surface of the support platform 41. As the lifting platform 42 continues to move, the buffer element 423 is compressed, and the buffer block 422 will gradually enter the buffer groove 421. At this time, the cutting blade 44 will also pass through the cutting groove 4221 to cut the silicon steel sheet, thereby making the cutting process more stable, making the cut of the silicon steel sheet smoother, and improving the production quality.

[0047] Reference Figure 1 and Figure 3 A discharge port 412 is provided on the surface of the support platform 41 on the side away from the transmission wheel 31. The discharge port 412 is triangular in shape and is used to discharge the triangular excess material between two adjacent side column silicon steel sheets cut from the silicon steel sheet belt. For this purpose, a drop groove 11 is provided on the surface of the frame 1 corresponding to the discharge port 412 to allow the excess material to enter.

[0048] Reference Figure 3 and Figure 5 Two hinged plates 7 are provided at the discharge port 412. Both hinged plates 7 are located below the support platform 41. In this embodiment, the hinged plates 7 are triangular in shape, and the right-angled sides of the two hinged plates 7 are adjacent to each other. One end of the hinged plate 7 is integrally formed with a rotating shaft 71 at an acute angle. The hinged plates 7 are rotatably connected to the bottom wall of the support platform 41 through the rotating shaft 71. When the hinged plates 7 rotate, the discharge port 412 will be exposed, thereby discharging the residual material that has passed through the discharge port 412. The side walls of the two hinged plates 7 that are adjacent to each other are integrally formed with baffles 76 to limit the falling trajectory of the residual material, so that the residual material can be accurately discharged.

[0049] Reference Figure 3 and Figure 6The opening and closing plate 7 has a countersunk groove 73 on its surface, and an abutment plate 74 is slidably connected in the countersunk groove 73. After the abutment plate 74 extends out of the countersunk groove 73, it will be flush with the surface of the support platform 41, so that the side column type silicon steel sheet can pass through stably. Several elastic elements 75 are provided in the countersunk groove 73. In this embodiment, the elastic element 75 is a combination of spring and guide rod. The bottom wall of the abutment plate 74 has a hole for the guide rod to be inserted, so that the abutment plate can slide along the length direction of the guide rod. The spring is sleeved on the periphery of the guide rod, and one end is connected to the bottom wall of the abutment plate 74 by adhesive. The other end is connected to the bottom wall of the countersunk groove 73 by adhesive. Driven by the elastic element 75, the abutment plate 74 always maintains the tendency to move away from the countersunk groove 73. The abutment plate 74 has a guide surface 741 facing the inner wall of the discharge port 412. When the opening and closing plate 7 rotates, the guide surface 741 will abut against the inner wall of the discharge port 412, thereby pushing the abutment plate 74 into the countersunk groove 73. This allows the silicon steel sheet to pass through when the opening and closing plate 7 is not rotated, and the abutment plate 74 can be automatically stored after rotation, which has high practicality and convenience.

[0050] Reference Figure 5 The bottom wall of the support platform 41 is provided with two guide plates 85, and the guide plates 85 and the opening and closing plates 7 correspond one to one. The surface of the opening and closing plates 7 is integrally formed with guide posts 72. The surface of the guide plates 85 is provided with limiting grooves 851 for the guide posts 72 to be inserted and slide. The limiting grooves 851 are arc-shaped and are opened along the rotation direction of the guide posts 72 to limit the movement trajectory of the opening and closing plates 7.

[0051] Reference Figure 5 The frame 1 is provided with a drive assembly 8 for driving the two opening and closing plates 7 to rotate in a direction that moves closer to or further away from each other. The drive assembly 8 includes a drive cylinder 81, a connecting plate 82, two drive racks 83 and two drive gears 84, wherein the drive racks 83, drive gears 84 and opening and closing plates 7 are arranged in a one-to-one correspondence.

[0052] Reference Figure 3 and Figure 5 The base of the drive cylinder 81 is welded to the bottom wall of the support platform 41. The piston rod of the drive cylinder 81 is set towards the opening and closing plate 7. The connecting plate 82 is welded to the piston rod of the drive cylinder 81. The two drive racks 83 are welded to the side of the connecting plate 82 near the opening and closing plate 7. The sides of the two drive racks 83 with teeth are close to each other. The drive gear 84 is sleeved on the circumferential wall of the corresponding rotating shaft 71. The two drive gears 84 are located between the two drive racks 83 on both sides. The drive gear 84 meshes with the corresponding drive rack 83. When the piston rod of the drive cylinder 81 moves, it will drive the two opening and closing plates 7 to rotate in a direction that is close to or far away from each other through the meshing relationship between the drive gear 84 and the drive rack 83, thereby exposing or closing the discharge port 412.

[0053] Reference Figure 1 and Figure 3 The frame 1 is equipped with a moving track 52 located below the punching device 5. The length direction of the moving track 52 is consistent with the length direction of the conveying track 3. Two adjusting plates 53 are slidably connected to the moving track 52. Two cylinders are provided on the surface of the frame 1, and the cylinders are correspondingly set with the adjusting plates 53, so that the corresponding adjusting plates 53 can be adjusted along the length direction of the moving track 52. The adjusting plates 53 correspond to the punching stations 51. Each adjusting plate 53 is equipped with a feed track 54, and the length direction of the feed track 54 is perpendicular to the length direction of the moving track 52. The punching station 51 is slidably connected to the corresponding feed track 54. Each adjusting plate 53 is also equipped with a cylinder to move the punching station 51. By setting the moving track 52 and the feed track 54, the punching device 5 can be adjusted, so that the punching device 5 can flexibly adjust the punching position on the silicon steel sheet to produce more specifications of silicon steel sheets and improve applicability.

[0054] The implementation principle of the cross-cutting system for cutting edge-column type silicon steel sheets in this application embodiment is as follows: the silicon steel sheet strip is transported on the conveying track 3. When it is transported to the target position, the oblique cutting device 4 and the punching device 5 are activated at the same time. The oblique cutting and punching of the silicon steel sheet are completed in the same process, so that the production of edge-column type silicon steel sheet can be completed in one cut. This saves the time of punching and oblique cutting in the traditional preparation process and improves the cutting efficiency.

[0055] The excess material between two adjacent side column type silicon steel sheets will be discharged through the discharge port 412. When the excess material runs to the discharge port 412, the drive component 8 will drive the opening and closing plate 7 to rotate, exposing the discharge port 412, thereby discharging the excess material, saving the time of manual cleaning of excess material, and further improving work efficiency.
