[0040] With reference to Figure 2 and Figure 3 , each cutter 222 is below a corresponding receiving table 5, so as to support the cut silicon steel strip when the cutter 222 falls for cutting; the receiving tables 5 and the conveying pieces 3 are arranged at intervals, and at least one conveying piece 3 is arranged between adjacent receiving tables 5, so as to ensure that the silicon steel strip can be conveyed to the receiving table 5 below the cutter 222. The receiving tables 5 and the conveying pieces 3 are slidingly connected to the shearing table 21 along the length direction of the shearing table 21, and the sliding positions can be fixed by, for example, bolts, so that when the position of the cutter 222 changes, the corresponding receiving table 5 can always move to be directly below the cutter 222.

[0041] With reference to Figure 2 , Figure 3 and Figure 4 , since the first punching part 22, the first punching V part 23, the second punching part 24, the third punching part 26, the second punching V part 27 and the fourth punching part 28 will generate corner waste when punching or punching a V-shaped notch, the receiving tables 5 corresponding to the first punching part 22, the first punching V part 23, the second punching part 24, the third punching part 26, the second punching V part 27 and the fourth punching part 28 are all provided with a material discharging assembly 6 for discharging the corner waste.

[0042] With reference to Figure 2 , Figure 3 and Figure 4The discharging assembly 6 comprises a fixing frame 61, a punching rod 62 and a linkage 63. The fixing frame 61 is fixedly connected to the corresponding receiving table 5. The punching rod 62 is slidingly connected to the side wall of the fixing frame 61 in the vertical direction. The linkage 63 specifically comprises a linkage rod 631 and a return spring 632. One end of the return spring 632 is fixedly connected to the side wall of the punching rod 62, and the other end is fixedly connected to the side wall of the fixing frame 61. The extension direction of the return spring 632 is parallel to the sliding direction of the punching rod 62. The side wall of the punching rod 62 is provided with a sliding groove 621 along the sliding direction thereof. One end of the linkage rod 631 is inserted into the sliding groove 621, and the other end is fixedly connected to the lifting frame 4. When the cutter 222 and the linkage rod 631 slide with the lifting frame 4, the end of the linkage rod 631 slides in the sliding groove 621. When the cutter 222 moves downward to contact the upper surface of the receiving table 5, the end of the linkage rod 631 is just moved to the position of the groove bottom of the sliding groove 621.

[0043] Referring to Figure 3 , Figure 4 and Figure 5 , the upper surface of the receiving table 5 and located directly below the punching rod 62 is provided with a blanking port 58. The upper surface of the receiving table 5 and located directly below the cutter 222 is provided with a giving slot 51. A supporting plate 52 and a supporting spring 53 are inserted into the giving slot 51. The supporting spring 53 is connected between the lower surface of the supporting plate 52 and the groove bottom of the giving slot 51. When the supporting spring 53 is not deformed, the upper surface of the supporting plate 52 is flush with the upper surface of the receiving table 5. When the cutter 222 continues to move downward after contacting the receiving table 5, the cutter 222 will press the supporting plate 52 to complete the shearing of the silicon steel strip and insert into the giving slot 51. At this time, the punching rod 62 moves downward under the pressing of the linkage rod 631 and inserts into the blanking port 58 to push the corner waste after shearing into the blanking port 58 and discharge from the receiving table 5.

[0044] Referring to Figure 4 and Figure 5 , the upper surface of the receiving table 5 with the giving slot 51 is provided with air holes 54. The air holes 54 are distributed in the inner and outer circles of the giving slot 51 and evenly distributed along the circumference of the giving slot 51. The air holes 54 are connected with the giving slot 51. The receiving table 5 is provided with a gas injection member 55. The gas injection member 55 specifically comprises a sealing gasket fixedly bonded to the side wall of the supporting plate 52. The sealing gasket can be made of rubber. The side wall of the sealing gasket away from the supporting plate 52 is attached to the inner wall of the giving slot 51. When the supporting plate 52 moves downward and inserts into the giving slot 51 under the pressing of the cutter 222, the sealing gasket cooperates with the cutter 222 to make the air in the giving slot 51 be extruded and discharged from the air holes 54 to the silicon steel strip on the receiving table 5, so as to facilitate the stripping of the silicon steel strip and the corner waste and the silicon steel strip and the cutter 222.

[0045] Referring to Figure 3 and Figure 4Each air hole 54 has a pin 56 slidably connected to its inner wall along its length. Each pin 56 is provided with a reset member 57, which can be a spring. The reset member 57 is connected between the pin 56 and the inner wall of the air hole 54, and the extension and retraction direction of the reset member 57 is parallel to the sliding direction of the pin 56. When the reset member 57 is not deformed, one end of the pin 56 away from the relief groove 51 is fully inserted into the air hole 54, while the other end of the pin 56 is inserted into the relief groove 51. The end wall of the ejector pin 56 near the relief groove 51 and the lower surface of the support plate 52 near each ejector pin 56 are provided with relief arc surface 561. The relief arc surface 561 is used to allow the end of the ejector pin 56 away from the support plate 52 to pass through the air hole 54 when the support plate 52 moves down to contact the ejector pin 56. The ejector pin 56 passing through the air hole 54 can further push the silicon steel strip or scrap material, further promoting the peeling of the silicon steel strip and scrap material, and the silicon steel strip and cutter 222. At the same time, it cooperates with the stamping rod 62 so that the scrap material can be quickly pushed into the discharge port 58.

[0046] Reference Figure 2 , Figure 3 and Figure 4 The inner wall of the discharge port 58 is also provided with an embedding groove 581. A cleaning rod 59 is rotatably connected to the inner wall of the embedding groove 581. The discharge port 58 is also provided with a cleaning component 591 for driving the cleaning rod 59 to rotate. The cleaning component 591 includes a position detector 5911, a controller 5912 and a drive component 5913. The drive component 5913 can be a motor. The motor drive shaft is connected to the rotation connection point between the cleaning rod 59 and the inner wall of the embedding groove 581. The cleaning rod 59 can be embedded in the embedding groove 581 or pass through the discharge port 58 during rotation. The corner waste entering the discharge port 58 is located on the rotation path of the cleaning rod 59.

[0047] Reference Figure 2 , Figure 3 and Figure 4 The position detector 5911 and the drive unit 5913 are both electrically connected to the controller 5912. The position detector 5911 can be a through-beam photoelectric switch embedded in the inner wall of the material discharge port 58. When the stamping rod 62 is inserted into the material discharge port 58, the light emitted by the transmitter of the through-beam photoelectric switch is blocked by the receiver. At this time, the position detector 5911 sends a photoelectric signal to the controller 5912. The controller 5912 can be a PLC controller. The controller 5912 is used to receive the photoelectric signal and, after a specified time, controls the drive unit 5913 to drive the unblocking rod 59 to rotate through the material discharge port 58 and then rotate back to the embedded groove 581 to reset. During the process of the unblocking rod 59 rotating and passing through the material discharge port 58, the corner waste will be scraped out of the material discharge port 58 by the unblocking rod 59, realizing automatic material discharge. The aforementioned specified time refers to the time from when the stamping rod 62 is inserted into the material discharge port 58 to when the stamping rod 62 moves upward and leaves the material discharge port 58.
