1、 垫圈冲孔落料级进模设计 I 摘 要 本设计进行了冲孔落料级进模的设计。文中简要概述了冲压模具目前的发展状况和 趋势。对产品进行了详细工艺分析和工艺方案的确定。按照冲压模具设计的一般步骤， 计算并设计了本套模具上的主要零部件，如：凸模、凹模、凸模固定板、卸料板、挡料 销、导正销等。模架采用标准模架，选用了合适的冲压设备。设计中对工作零件和压力 机规格均进行了必要的校核计算。此外，本模具采用始用挡料销和固定挡料销。落料凸 模内装有导正销，保证了工件上孔和外形的相对位置准确，提高加工精度。如此设计出 的结构可确保模具工作运行可靠和冲压产品大批量生产的要求。 关键词关键词: : 级进模；校核；冲孔；
2、落料 II Abstract The design of the banking and punching progressive modulus design.This paper briefly outlined the Stamping Die current development status and trends.The product of a detailed analysis and the identification process.Stamping die design in accordance with the general steps to calculate
3、and design the sets on the main mold parts,such as:punch and die.Punch plate,feet behind the sales,marketking and other derivative is.Die-standard model planes,to choose a suitable stamping equipment.Dsign work on the parts and specifications will press for the necessary checking caculation.In addit
4、ion,the die block used only with marketing materials and immovable the marketing materials.Blanking punch contents is a derivative sales,and guarantee the workpiece and the shape of the holes in the relative position,imprve processing accuracy.So the structure is designed to ensure reliable operation of die stamping products and mass production requirements.
