when the sliding block 622 slides to a lower end close to the sliding rail 82, when the lower surfaces of the discharging plate 421 and the pressing plate 422 are in contact with a silicon steel sheet placed on the lower die holder 2, the pressure sensor detects pressure and transmits a signal to the electromagnet 4211, the electromagnet 4211 is automatically electrified to adsorb the silicon steel sheet, the hydraulic cylinder 31 drives the blanking die 41 to continuously descend, so that the blanking knife penetrates through the silicon steel sheet and extends into a lower die groove, the stator punching sheet 71 and the rotor punching sheet 72 are cut on the lower die holder 2, waste materials cut by the blanking knife are ejected out through the force of the second elastic element 416 and fall into a waste box, and in the process, the discharging plate 421 and the pressing plate 422 are pressed on the surfaces of the punched stator punching sheet 71, the rotor punching sheet 72 and the unmapped part of the silicon steel sheet;
after blanking of a group of stator punching sheets 71 and rotor punching sheets 72 is completed, the hydraulic cylinder 31 drives the bearing platform 32 to ascend, and drives the connecting seat 33, the blanking die 41, the discharging assembly 42 and the stator punching sheets 71 and the rotor punching sheets 72 adsorbed by the electromagnets 4211 to ascend; during the ascending process of the bearing platform 32, the first connecting rod 53 drives the reversing seat 51 to turn over in the counterclockwise direction, the driving rod 52 is driven to rotate in the counterclockwise direction through the second connecting rod 54 and the first fixing rod 55, the driving rod 52 drives the third connecting rod 57 to move in the direction close to the feeding end through the second fixing rod 56, and then the mounting seat 62 is pushed to move obliquely upwards along the material guiding support 8 through the assembling shaft 621;
when the sliding block 622 slides to the higher end of the sliding rail 82, the lower die holder 2 and the upper die holder 4 are in a complete die opening state, the feed end of the material receiving plate 61 is positioned under the blanking die 41, at this time, the electromagnet 4211 is automatically powered off, so that the stator punching sheet 71 and the rotor punching sheet 72 adsorbed by the electromagnet automatically fall off and fall onto the material receiving plate 61, wherein the stator punching sheet 71 is conveyed from the upper end of the inner guide rail 612 and continuously slides into the stator receiving box along the extension guide rail 83, and the rotor punching sheet 72 is conveyed between the inner guide rails 612 and falls into the rotor receiving box from the discharge port at the front side of the cross bar 84, so that automatic material distribution is realized;
along with the hydraulic cylinder 31 driving the bearing table 32 to do reciprocating lifting motion, the blanking die 41, the discharging assembly 42 and the material receiving plate 61 are driven to run in a mutually matched mode, and continuous blanking and full-automatic material receiving of the stator punching sheet 71 and the rotor punching sheet 72 are achieved.
