When the hammer rod 301 breaks, the falling speed of the forging hammer 305 increases. At this time, the signal strength of the pressure sensor 803 changes exponentially. When the controller receives the pressure After the signal from the sensor 803, the switch of the electromagnet 614 is first turned on, so that the electromagnet 614 generates magnetism and absorbs the iron block 612. Under the action of the second connecting rod 611, the two limiting blocks 610 are driven to shrink into the inside of the rectangular hole, At this time, under the action of the second spring 609, the buffer plate 605 is pushed away from the support 103 by the connecting frame 607, the limiting column 608 and the support rod 606. Since the buffer plate 605 moves, it contacts the buffer plate 605 during the rotation of the connecting plate 604. , the second spring 609 realizes the buffering of the connecting plate 604, and then realizes the buffering of the forging hammer 305 through the transmission rod 603, the sleeve 601, the sleeve rod 602 and the connecting seat 306, and the controller closes the solenoid valve 403 at the same time, and the solenoid valve 403 After closing, the space formed by the negative pressure box 401 and the piston plate 404 forms a seal, so that the force required for the piston plate 404 to descend is greater. Therefore, under the action of the transmission plate 405, the hammer rod 301 is buffered to avoid breakage. The hammer rod 301 smashes against the forging and collapses, which further improves the safety degree.
