本科毕业设计题目：医疗器盒冲压工艺与模具设计学 院:材料与冶金学院专 业:材料成型及控制工程学 号:学生姓名:指导教师:日 期:2015.03.01-2015.06.01摘 要在日常生活中医疗器盒等盒形零件的使用非常频繁，因此盒形件的冲压模具设计显得比较重要。在冲压成型过程中，由于盒形件坯料受力沿周边是不均匀的，这无疑大大增加了盒形件的冲压模具设计的难度。医疗器盒是中心对称的矩形盒，底部设计有加强筋。矩形盒部分通过拉深完成，底部加强筋通过胀形完成。医疗器盒的材料选择 10 钢。由于医疗器盒的高度比较小，经核算可一次拉深成型。考虑到零件尺寸和生产需求，采用正装落料拉深胀形复合模，正装模具可提高模具使用寿命并有效保证零件质量。在确定模具形式后，进行了坯料尺寸计算，排样设计，冲裁力、推件力顶件力、拉深力、胀形力计算。通过工艺力的计算选择合适的压力机。根据医疗器盒的尺寸以及之前的工艺力计算，确定落料、拉深和胀形工作零件的刃口尺寸。之后完成工作零件（如拉深凸模、落料凹模、凸凹模和胀形凸、凹模）、定位零件、卸料版、固定板等部件的合理结构设计并绘制零件图。最后完成各个部件组合的整体装配图。关键词：医疗器盒；冲压工艺； 拉深； 模具设计AbstractMedical device box -shaped parts is very frequent in the daily life, so the stamping die design of box-shaped parts is more important. In the stamping process, the box-shaped blank force along the periphery is not uniform, which leads to the stamping die design of box shaped parts increases the difficulty of many.The medical device box is the center of the rectangular box, and the rib reinforcement is designed in bottom. The rectangular box is finished by drawing and the bottom is strengthened by bulging. 10 steel is selected of medical materials device box -shaped parts. Because the medical box height is relatively small, it can be completed by a deep drawing. Considering the size of parts and production requirements, adopting blanking-drawing compound die, which can enhance the service life of the die and effectively ensure the qua...
