1、计算机软件在模具设计中的应用 摘要摘要 模具在汽车、拖拉机、飞机、家用电器、工程机械、动力机械、冶金、机床、 兵器、仪器仪表、轻工、日用五金等制造业中,起着极为重要的作用。采用模具 生产毛坯获成品零件,是材料成形的重要方法之一,与切削加工相比,具有材料 利用率高、能耗低、产品性能好、生产效率高和成本低等显著特点。冲压模具是 一种少、无切屑加工方法,在模具总产值中约占 59%,其中在汽车制造业中,有 60%70 的零件时采用冲压工艺制成的, 冲压生产所占的劳动量为整个汽车工 业劳动量的 25%35%,在电子产品中冲压件的数量占零件总数 85%以上。在许 多先进的工业国家,冲压生产和模具工业得到了
2、高度重视,例如美国和日本,模 具工业的年产值已超过机床工业年产值1 3。因此,模具工业已成为重要的产业, 而冲压生产则成为生产优质先进机电产品的重要手段之一。 模具 CAD/CAE/CAM 是改造传统模具生产方式的关键技术, 是一项高科 技、 高效益的系统工程。它以计算机软件的形式,为企业提供一种有效的辅助 工具,使工程技术人员借助于计算机对产品性能、模具结构、成形工艺、数控加 工及生产管理进行设计和优化。模具 CAD/CAE/CAM 技术能显著缩短模具设计 与制造周期,降低生产成本和提高产品质量已成为模具界的共识。 关键词:模具设计;模具 CAD/CAE/CAM; AbstractDie I
