基于Pro/E钣金件的四岔管分析设计

Four bifurcated pipe analysis and design based on Pro/E sheet metal part

为了实现高精度、流体阻力小的四岔管制造要求,采用了Pro/E软件基于特征参数化建模、Pro/E钣金设计的钣金特性及Pro/E的D raw ing模块等方法,分别完成了最佳三维实体的四岔管模型创建、组装,四岔管的分型平面展开及四岔管零件的2D工程图。分析结果表明,利用该方法可以为中小型企业提供精确的生产用图,该设计降低了生产过程中的废品率,使设计者能运用该方法对相关岔管进行设计,提高了相关的设计能力。

Aiming at realizing the requirement of manufacturing high precision and small fluid resistance,the model method was adopted based on characteristic parameterization,the sheet metal designs and the drawing modules in Pro/Engineer.Making use of the method,the foundation and assembling of the optimum three dimensional solid model of four-fork tubes were completed,in addition the parting plane＇s opening and the 2D engineering drawing were accomplished.The results show that the method may provide the accurate production plans for the small and medium enterprises,and the rejection rate in the production process is reduced,the designer can apply the method to design the related production and to improve the inventive skill.
