设计简介
中文摘要
本设计是落料、冲槽复合模的设计。设计说明书中简要概述了冲压模具目前的发展状况和发展趋势。然后对工件进行了详细工艺性分析以及冲压方案的确定。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、凸凹模、凸模固定板、垫板、凹模固定板、卸料板、挡料销、推件板、顶件块等。模架采用标准模架，选用了合适的冲压设备。
关键词：落料, 冲槽, 复合模, 冲压模具, 凸凹模
Abstract
This is a design of dropping and Notching composite die. The design overview the current development status and development trends of stamping die briefly. Then I conduct a detailed analysis of the work piece and determine the Stamping program. After finishing the Stamping die design in accordance with the general steps,I also design and calculations the main parts of this mold .For example, Punch, Die, Die punch, punch plate, plate, Die plate and dump plates, block information, marketing pieces of boards, blocks and other top pieces . At last I use standard mold and choice the suitable Stamping equipment.
Keywords : dropping; Notching ; compound die; stamping die; Die punch.
