[0036] In some embodiments, a rotating assembly 11 is installed in the middle of the inner side of the base 1. The rotating assembly 11 includes a driving motor 1101.

[0039] Working principle:

[0040] First of all, during use, the hydraulic rod 5 drives the stamping block 6 to move downward for stamping the metal plate. After stamping, the metal plate will retract into the stamping block 6, causing the squeezing plate 901 inside the blanking component 9 to slide inward. The squeezing plate 901 cooperates with the use of the first support rod 903, the second support rod 904 and the spring 905 above, so that the metal plate stamped into the stamping block 6 will bounce down under the reset action of the spring 905 for blanking of the metal plate.

[0041] After the metal plate is blanked, it will fall onto the electromagnet 1102 and the rubber block 14 above the rotating assembly 11. By turning on the electromagnet 1102 to adsorb the metal plate, and then by turning on the second servo motor 1201 on the grinding assembly 12, the second servo motor 1201 drives the bidirectional lead screw 1202 to rotate, so that the bidirectional lead screw 1202 drives two groups of movable blocks 1203 to move in a threaded manner, making the grinding blocks 1205 on the mounting plates 1204 at the ends of the movable blocks 1203 contact the two ends of the metal plate. Then, by using the electric telescopic rod 1206, it is convenient to drive the mounting plate 1204 to move up and down relative to the grinding blocks 1205, facilitating the grinding work on both sides of the metal plate. After the two ends of the metal plate are ground, by using the drive motor 1101 on the rotating assembly 11, the electromagnet 1102 can be rotated, facilitating the adjustment of the metal plate and the grinding work on the other two sides of the metal plate, improving the processing effect of the metal plate;

[0042] After the metal plate is processed, by turning on the first servo motor 1001 on the discharging assembly 10, the first servo motor 1001 drives the unidirectional lead screw 1002 to rotate, so that the unidirectional lead screw 1002 drives the discharging plate 1003 to slide on the positioning rod 1004, and the discharging plate 1003 discharges the metal plate.

[0043] The auxiliary device for blanking of the stamping die of the metal plate of the present utility model can, through the cooperation of the blanking assembly and the discharging assembly, facilitate the automatic auxiliary discharging and discharging of the stamped metal plate, facilitating the discharging work of the metal plate and improving the use effect of the device.

[0044] The auxiliary device for blanking of the stamping die of the metal plate of the present utility model, through the use of the grinding assembly inside the base, can drive the grinding material on the surface of the mounting plate to fit against both sides of the metal plate by means of the movable block. In cooperation with the use of the electric telescopic rod, it is convenient to grind both sides of the metal plate.
