1、套环冲压工艺与模具设计摘要:冲压模具在实际工业生产中应用广泛。在传统的工业生产中,工人生产的劳动强度大、劳动量大,严重影响生产效率的提高。随着当今科技的发展, 工业生产中模具的使用已经越来越引起人们的重视,而被大量应用到工业生产中来。冲压模具的自动送料技术也投入到实际的生产中,冲压模具可以大大的提高劳动生产效率,减轻工人负担,具有重要的技术进步意义和经济价值。 冷冲压是一种先进的金属加工方法,它是建立在金属塑性变形的基础上,利用模具和冲压设备对板料金属进行加工,以获得所需要的零件形状和尺寸。冷冲压具有生产率高、产品尺寸精度稳定、操作简单、加工成本低、材料利用率高、容易实现机械化和自动化等一系列
2、优点,特别适合于大量生产。 本文主要是根据零件的生产技术要求,设计了落料拉深冲孔和翻边模复合再一起。因为板料、设备和模具是构成冲压加工的三个必要因素,此三要素是冲压所必要的硬件条件,再通过人们的对他们在有机地协调 ,包括进行合理的工艺性设计、计算以有效的组织管理。有在整个设计过程中,分性零件加工工艺和模具的设计是同样的重要,同时模具是为实际生产所服务,所以,设计出来的模具结构不但要可行,即达到预期目的,而且要让工人操作起来简单方便,另外还要尽量少花钱,即经济性。关键词:冷冲压, 落料, 拉深, 冲孔, 翻边 Pressing Technology and Die Design of Lante
