订书机支架自动出件级进冲压模具设计

根据订书机支架的材料、结构特点和尺寸精度要求,分析其冲压成形工艺性能,完成冲压工艺方案和模具结构的设计。确定订书机支架采用多工位级进模来成形。详细介绍了模具的主要结构特点及工作过程。根据零件结构特点,选择纵向排样进行设计,该排样方案包括冲孔、空工位、端部弯曲、空工位和切断、侧边弯曲5个工位。为了配合自动送料装置,模具设计了自动出件装置,采用楔形滑块结构,利用开合模动作,实现对成形件的自动推出;另外,为了保证条料的顺利送进,模具设计了浮顶装置。结果表明:采用多工位级进模成形订书机支架,可满足该零件所有特征的成形要求,实现高质量、高效率的冲压生产。

Design of stamping progressive die with automatic ejecting device for stapler stand

The stamping process performance was analyzed according to materials,structure characteristics and dimension precision of stapler stand,and the stamping process scheme and die structure were designed. The multi-station progressive die was adopted to produce stapler stand. The main structure characteristics and working process of die were introduced in detail. According to the characteristics of part structure,the longitudinal layout was chosen to design,and the layout scheme includes five stations of punching,idle station,end bending,idle station,cutting and side bending. In order to cooperate with automatic feeding device,the automatic ejecting device with wedge slider structure was designed to realize automatic pushing-out of formed parts by the opening and closing actions of die. And floating roof device was designed to ensure the smooth delivery of strip. The results show that the forming requirements for all characteristics of stapler stand formed by the multi-station progressive die can be realized,and the stamping production of high quality and high efficiency is achieved.
