顶罩冲压模设计
本次毕业论文设计的题目为顶罩冲压模设计。
首先对冲压进行了工艺性的分析，确定冲压工艺方案，选择了冲压模结构；
然后进行了排样的设计，确定压力机，计算凹凸模间隙并确定刃口尺寸；
最后进行冲压模零件结构设计与计算。
此零件在结构、精度、粗糙度等指标上都满足要求，模具的类型为复合模，送料方式采用自动送料，卸料方式为弹性卸料方式，横向定位装置为导料板（不用侧压装置），纵向定位装置为固定挡料销，导向方式采用中间导柱，算的材料利用率为75.2%，根据零件尺寸，以及之前算的各个部分的基本数据，得出排样使用直排方式，总的冲裁力F=170KN，推件力Ft=9.4KN，拉深力F拉=98KN，翻边力F==48KN，模具总冲压力为模具各个工步的冲压力总和；
选取JA23-63压力机。
凹形模的外形尺寸D×
H=200×
40mm，凸模长度：
L=67mm，经校核合格。
上模板为200×
50mm，下模板为200×
60mm，导柱32×
210mm，导套32×
115×
45mm。
在设计的过程中，会遇到很多难以解决的问题，但到最后还是圆满的完成和解决。
例如很多本次冲压模设计以立足于实际，服务于企业制造为宗旨。
设计上科学合理，模具构造简介、易于维护，所选工件皆为最优，为从事类似方向的冲压模设计者提供了一个参考样本，而且对冲压模的不断向前发展有所裨益，最终使百姓受益。
