[0024] The specific operation is as follows: the staff places the workpiece to be processed between the first roll forging die 1 and the second roll forging die 4, and uses the driving motor 601 in the driving assembly 6 to drive the rotating rod 603 to rotate. Because the two ends of the rotating rod 603 pass through the movable vertical plate 5 and are fixedly connected to the first gear 604, the first gear 604 rotates accordingly, so that the second gear 605 meshing and rotatingly connected below the first gear 604 also rotates synchronously. The middle section of the rotating rod 603 is fixedly connected to the second roll forging die 4, and the middle section outer wall of the rotating rod 2 fixedly connected to the center of the second gear 605 is fixedly connected to the first roll forging die 1.

Because the engaging movable bar 907 is welded on both sides of the movable vertical plate 5, as the engaging movable bar 907 moves up and down, the movable vertical plate 5 also moves up and down, thereby adjusting the distance between the first roll forging die 1 and the second roll forging die 4, which is convenient for the staff to process railway splints of different specifications and improve the application range of the roll forging composite die. The structure is simple, which is convenient for the staff to operate and convenient for the staff to use the roll forging composite die.
