1、哈尔滨理工大学学士学位论文冲孔落料连续模设计及三维CAD实体动画仿真摘要连续模,又称为多工位连续模、级进模、跳步模,它是在一副模具内,按所加工的工件分为若干等距离的工位,在每个工位上设置一个或几个基本冲压工序,来完成冲压工件某部分的加工。被加工材料,事先加工成一定宽度的条料,采用某种送进方法,每次送进一个步距。经逐个工位冲制后,便得到一个完整的冲压工件。在一副级进模中,可以连续完成冲裁、弯曲、拉深、成形等工序。一般来说,无论冲压零件形状怎样复杂,冲压工序怎样多,均可用一副级进模冲制完成。本设计为冲孔、落料两工位级进冲裁模。首先,分析工件的尺寸及精度要求等个方面的信息和要求,确定排样图和模具
2、型式及总体结构方案。然后根据工件分别计算和设计各2D零件草图及修改、检验、校核。接着,设计挡料装置及定位装置,由于本设计工件的精度要求不高且生产为中、大批量故采用自动挡料装置和定位销装置即可满足要求。最后,检验无误后,用Pro/E软件生成3D实体进行动画仿真,以校验该设计的合理性及正确性。关键词 连续模具;冲裁模;模具设计;仿真动画;Pro/E-II-哈尔滨理工大学学士学位论文PunchingcutMulti-positionprogressivemoldDesignAnd3D-CADAnimationSimulationAbstractConsecutivemodules,alsokno
