基于参数化特征的冲压模具标准斜楔建模方法

Modeling Method of Standard Cam for Stamping Dies Based on Parametric feature

提出了一种基于特征和全参数化驱动的标准斜楔建模方法,并将其无缝集成到NX软件平台。通过工作角度参数的驱动,结合参数化草图、标准件的全约束关联装配和细节特征的关联修饰,采用自上而下的建模思路,创建了全参数化的斜楔模型,实现了将同一系列不同工作角度规格的模型集成到统一的模型中。只需修改工作角度,系统就可以自动实例化不同工作角度的斜楔模型并加载至NX中。实例表明,该建模方法可以显著提高标准斜楔的设计质量和效率,精简了斜楔的模型数据。

A new modeling method of standard cam based on feature and full parameter ＂driving was proposed, which is seamlessly integrated in NX software platform. The models of different work angles of the same series of cam are integrated into a unified model, which is fully parametric driven by work angle and modelled by top-dawn drawing, fully constrained assembly of standard parts and modification of detail features. Only by changing the work angle the system automatically instantiate the cam model of different work angles and load it into NX. The example shows that this modeling method and system can improve the design quality and efficiency of the standard cam significantly, and simplify the model data.
