摘要
随着全球经济一体化的深入,模具工业在国民经济中所发挥的作用越来越明显。模具设计水平的高低直接影响产品的质量及生产效率。
设计本模具是为了制造普通 U 形弯件。设计中分析了零件的结构及工艺性,拟订该零件的冲压工艺为“切边—弯曲”,讨论了弯曲零件毛坯展开形状和尺寸的确定方法,设计了落料模和弯曲模,对关键零件的结构设计作了详细阐述,并指出了模具设计时的注意事项。其中,弯曲成形模是本设计的重点,将切边弯曲集中于一套模具中,使得冲件的质量和生产效率较高,满足了生产
需要。
由于模具设计是一种经验性较强的设计,经过长期发展积累了大量丰富的冲压工艺技术资料, 在设计这两套模具时必然要借鉴这些经验数据,含括了落料模、弯曲模、拉深模中常用的工艺数据以及模具材料的选取和压力机基本参数等等.

Abstract
Along with global economic integration thorough, the mold industry the function which displays in the national economy is more and more design level height direct influence product quality and production efficiency. Designs this mold is in order to make ordinary U shape the design has analyzed ponents structure and the technology capab ility, drafts ponents the ramming craft is “the cutting edge - - curving”, discussed the ponents semifinished materials to launch the shape and the size definite method, has designed the cut die and the bending die, has made the detailed elaboration to the ponents structural design, and had pointed out the mold designed when matters needing them, the curving molding machine is this design key point, concentrates curving the cutting edge in set of molds, caused to flush a quality and the production efficiency is high, has met the production needs. Because the mold design is one kind of empirical strong design, passed through the long -term development to accumulate the massive rich ramming processing technology material, when designed these two sets of molds had to profit from these empirical data inevitably, including has included the cut die, the bending die, in the drawing mold monly used craft data as well as mold material selection and press basic para meter and so on.
