摘　　要：介绍了一种铝合金圆管双头冲孔与翻孔模具,描述了该模具的结构组成,介绍了凸模、凸凹模、凸凹模保护结构及限位结构等工作原理。实践表明,该模具可适用于生产不同管径和长度的圆管系列零件,模具结构简单紧凑,提高了生产效率,降低了模具制造成本。The design of piercing die and plunging die for both ends of round tube was introduced, and the structure of the die was described in detail. The working principle of the punch, punch-matrix, the protection structure and limit structure of the punch-matrix were described. The practice showed that the structure was suitable for the series of tubes with different diameters and lengths. Practice proved that different diameter and length of the tube could be produced by the die and the structure of the die was simple and compact.
