when the upper die 1 moves downwards, the bottom surface of the upper die 1 pushes the second material supporting rod 27 and the top surface of the first material supporting rod 24, so that the first material supporting rod 24 moves downwards, meanwhile, due to the fixed connection between the first material supporting rod 24 and the sliding plate 21, the sliding plate 21 also moves downwards, meanwhile, due to the design of the first one-way bearing, the first transmission gear 14 can not drive the second transmission gear 23 to rotate, and errors between the first transmission rack 12 and the second transmission gear 23 are prevented, so that the top surfaces of the second material supporting rod 27 and the first material supporting rod 24 are not in the same horizontal plane with the bottom surface of an inner cavity of a forming cavity of the lower die 11, and the forming of a workpiece is affected;
when the sliding plate 21 moves downwards, due to the arrangement of the second unidirectional bearing 295, the fourth transmission gear 296 does not drive the rotating rod 293 to rotate, so that the third transmission rack 28 cannot be subjected to external force when the sliding plate 21 moves downwards, due to the design of the return spring 298, the third transmission rack 28 can move downwards relative to the mounting tube 25, and then the second material supporting rod 27 is reset, so that the top surface of the second material supporting rod 27 and the top surface of the first material supporting rod 24 are in the same horizontal plane, and forging forming of a workpiece by the device is facilitated.
