| 中文摘要: |
| 基于 NX 平台,开发了一种考虑铸件加工属性的汽车模具干涉检查功能。 在汽车车身模具结构设计中,对于凸模、压边圈等铸件实体,由于存在铸造偏差,铸造过程中需在设计的型面上增加一定厚度的加工余量,后续再对该部分型面上进行 NC 加工。 开发的功能在对整个模具结构进行间隙检查时,可以综合分析铸件与铸件,铸件与 NC 加工型面以及 NC 加工型面与 NC 加工型面等 3 种间隙类型。 最后以一结构设计实例,演示了间隙检查功能。 |
| 英文摘要: |
| An auto mold interference checking software in which cast processing properties were taken into consideration was developed based on the application development of Unigraphics NX 3D design platform. During auto mold structure design, casts, such as punch , blank holder and so on, need to add margin on specific surfaces during casting process because of cast deviation, then numerical control is used to process these surfaces. In checking the interference of all the mold assembly structures, this software can comprehensively considerate the clearance between cast and cast, cast and NC process surface, NC process surface and NC process surface. At last a mold example is used to show the interference checking. |
