After the driving motor 410 is started, the third gear 720 and the fourth gear 730 rotate synchronously, the fourth gear 730 drives the rack 440 to slide, and at this time, under the resistance of the resistance pin 620, the sliding block 420 slides towards the fifth contact sensor 490. When the sliding block 420 abuts the fifth contact sensor 490, the air pump 310 and the graphite pump 360 are activated, and at the same time, the sliding block 420 no longer slides due to the resistance of the fifth contact sensor 490, and the resistance pin 620 is disengaged from the resistance pin 620 groove. At this time, the first rotary disk 450 is rotated once by the driving of the rack 440, so that the upper air nozzle 330, the lower air nozzle 340, the upper ink nozzle 380, and the lower ink nozzle 390 are rotated once in the circumferential direction of the mold, and then the finish forging lower mold 141 is blown and ink is ejected.

When the resistance pin 620 enters the groove of the resistance pin 620 again, the resistance pin 620 abuts against the seventh contact sensor 510, the seventh contact sensor 510 sends out a pulse signal, the seventh contact sensor 510 controls the electromagnet 770 to be electrified, and the fixture block 790 is clamped in the third clamping groove 211. When the latch 790 is latched in the third latching groove 211, the rotating shaft 710 is fixed to the bracket 210, and the third gear 720 and the fourth gear 730 rotate in opposite directions. The driving motor 410 continues to rotate to slide the rack 440 toward the sixth sensor, and the sliding block 420 slides toward the sixth contact sensor 500 by the resistance pin 620 until the sliding block 420 abuts against the sixth contact sensor 500. Under the resistance of the sixth contact sensor 500, the resistance pin 620 is again released from the groove of the resistance pin 620, the first rotary disk 450 is rotated in the reverse direction one rotation and is restored, and the resistance pin 620 again falls into the groove of the resistance pin 620. The resistance pin 620 is abutted against the seventh contact sensor 510, the seventh contact sensor 510 sends out a pulse signal, the seventh contact sensor 510 controls the electromagnet 770 to lose power, and simultaneously, the driving motor 410 is stopped under the combined action of the sixth contact sensor 500 and the seventh contact sensor 510.

Referring to fig. 3 and 13, the second contact sensor 123 and the first laser sensor 124 are also electrically connected to a driving motor 410 of the first cooling device 170. When the preliminary forging and pressing is completed and the first robot 130 takes the blank out of the pre-forging lower die 122, the second contact sensor 123 is powered on, the first laser sensor 124 is powered off, and the driving motor 410 moves at the moment, so that the pre-forging upper die 121 and the pre-forging lower die 122 are cooled.

Referring to fig. 5 and 13, the third contact sensor and the third laser sensor 145 are also electrically connected to the driving motor 410 of the second cooling device. When the complete forging is completed and the second robot 150 removes the blank from the finish forging lower die 141, the third contact sensor 143 is powered on, the third laser sensor 145 is powered off, and the driving motor 410 is driven, so that the finish forging upper die 142 and the finish forging lower die 141 are cooled.

The forging technology and the forging production line in the embodiment of the application have the implementation principles that:

the first robot 130 takes the blank from the loading frame 110 and places the blank on the pre-forging machine 120, after the pre-forging machine 120 performs primary forging on the blank, the first robot 130 places the blank on the finish forging machine 140, and at the moment, the first cooling device 170 cools the pre-forging upper die 121 and the pre-forging lower die 122; after the finish forging machine 140 completely forges the blank, the second robot 150 places the blank on the edge carving machine, and the second cooling device cools the finish forging upper die 142 and the finish forging lower die 141 at the moment; after the edge carving machine removes burrs of the blank, the second robot 150 takes the blank off the edge carving machine.
