Zusammenfassung:	The invention discloses a machining die for a vehicle roof board bent beam in a railway truck hood. The machining die comprises an upper die seat, an upper plate, an edge-pressing ring cushion plate, an edge-pressing ring, a male die, a female die, a lower plate, a lower die seat, a suspender bolt, a first spring, a second spring and a pressing bolt. The upper plate is fixedly connected to the upper die seat. The edge-pressing ring cushion plate is fixedly connected with the upper plate. The edge-pressing ring is fixedly connected with the edge-pressing ring cushion plate. The upper end of the male die sequentially penetrates the edge-pressing ring and the edge-pressing ring cushion plate. The female die is fixedly connected with the lower plate. The lower plate is fixedly connected with the lower die seat. The suspender bolt penetrates the edge-pressing ring cushion plate and is fixedly connected with the upper die seat. The first spring is arranged on the suspender bolt in a sleeving manner. The upper end and the lower end of the first spring abut against the upper die seat and the edge-pressing ring cushion plate respectively. By means of the machining die, the edge width error of workpieces produced through the machining die is small.
