The output end of the hydraulic rod three 706 is shortened, so that the push plate 705 connected to the hydraulic rod three 706 is inserted into the side groove 704, and after contacting the bottom sheet, the sheet is pushed out from the side opening of the interlocking frame 701 close to the operating table 1. Repeat the above operation to push a sufficient number of sheets out of the storage frame 702 and arrange them in sequence between the mold core 10 and the molding lower mold 13.

[0038] In specific application scenarios, the continuous feeding module 7 is mainly suitable for the continuous feeding link in the continuous feeding process, that is, the continuous feeding module 7 uses the hydraulic rod three 706 and the push plate 705 to continuously provide the plate in the storage frame 702 to the equipment for punching, thereby improving the continuity of the equipment operation, reducing the intermittent downtime of the equipment during the punching process, and increasing the output of the equipment's die core.

[0039] An electromagnet core die punching method, using the electromagnet core die punching device as described above, comprises the following steps:

[0040] Step 1: After adding the sheet to be punched to the storage frame 702 on the flat plate 11, the continuous feeding module 7 is used to push the sheet into the device, and the hydraulic rod 1 5 is started. The output end of the hydraulic rod 1 5 is extended, so that the mold core 10 installed on the upper mold base 12 of the device and the forming lower mold 13 on the operating table 1 punch the sheet (before the device starts punching, the sheet is placed in the storage frame 702 through the guide plate 703, so that the lower sheet falls into the embedded frame 701, and the hydraulic rod 3 706 is started. The output end of the hydraulic rod 3 706 is extended. The push plate 705 connected to the hydraulic rod 3 706 is shortened, so that the push plate 705 connected to the hydraulic rod 3 706 is inserted into the side groove 704, and after contacting the lowest plate, the plate is pushed out from the side opening of the fitting frame 701 close to the operating table 1. The above operation is repeated to push a sufficient number of plates out of the storage frame 702 and arrange them in sequence between the mold core 10 and the forming lower mold 13. The hydraulic rod 15 is started, and the output end of the hydraulic rod 15 is extended, so that the mold core 10 installed on the upper mold base 12 of the device and the forming lower mold 13 on the operating table 1 punch the plate);

[0041] Step 2: Use the collecting module 9 to collect the iron cores obtained by the die. After replacing the die core 10, use the leveling calibration module 8 to level the die core 10 so that the die core 10 can be perfectly matched with the forming lower die 13 during the die punching process (in the process of die punching, the iron core formed by the die punching enters the transfer slot 901 through the drop hole 902 below the forming lower die 13. After the iron core falls onto the buffer plate 910, the spring 2 904 below the buffer plate 910 absorbs the impact force, so that the iron core stops steadily on the buffer plate 910, and the hydraulic rod 2 906 is started. The output end of the hydraulic rod 2 906 extends to push the push plate 907 pushes the iron core on the buffer plate 910 onto the inclined surface of the inclined guide groove 908, so that the iron core can slide through the inclined surface into the collection box 909. When it is necessary to disassemble and replace the mold core 10, hold the crank 807 and rotate it to rotate the crank 807 connected to the crank 807 by 180 degrees, so that the inclined surface semi-ring 2 809 and the inclined surface on the inclined surface semi-ring 2 809 match each other. Under the pull of the spring 1 806, the inclined surface semi-ring 1 808 moves toward the upper mold base 12 and fits with the inclined surface of the inclined surface semi-ring 2 809, so that the long rod 804 can move in the round-mouth groove 803 in the direction of the spring 1 806. The short plate 811 connected to the long rod 804 drives the insertion bolt 812 to slide in the rectangular groove 810, thereby pulling out the insertion bolt 812 engaged in the engaging groove 813, so that the upper mold base 12 releases the lock on the stabilizing plate 802, and the stabilizing plate 802 connected to the mold core 10 is pulled out. According to the above operation, the replaced mold core 10 is reinserted and locked on the upper mold base 12, and the thrust of the spring 4 824 is overcome to push the translation ring 821 to slide on the limit piece 822 toward the center position of the mold core 10, so that the rack 823 on the translation ring 821 releases the gear ring 823 from the gear ring 823. 20 is locked, and knob 825 is turned. Knob 825 drives gear ring 820 to rotate, so that screw rod 819 is extended or shortened from stabilizing plate 802, and ball seat 818 on the extended or shortened screw rod 819 is slightly rotated in ball hole seat 817, so that the horizontal angle of one corner of mold core 10 connected to ball hole seat 817 is changed, and the remaining three screw rods 819 are adjusted according to the above steps until mold core 10 is in a horizontal state, and translation ring 821 is loosened. Under the push of spring four 824, translation ring 821 is reset, so that rack 823 is re-engaged with gear ring 820, and screw rod 819 no longer rotates).
