钣金件的放样设计和展开下料是产品开发和生产过程中重要的一环。针对以往下料前都是通过手工放样来绘制展开图,工作量大,效率低,研究应用三维软件SolidWorks钣金模块对90°三节渐缩弯头进行辅助放样设计,不仅能很方便地展开下料,而且提高了生产效率。实践证明,三维软件辅助放样展开法与传统钣金展开放样方法相比,具有设计精确、操作快捷和便于修改的优点。 Loft sheet metal design and unwinding is an important part of product development and production process. For the past before the material is drawn by hand to expand the plan, heavy workload, low efficiency, research and application of SolidWorks SolidWorks sheet metal module 90 ° three-section tapered elbow aids to staking out the design, not only can be easily developed Material, but also improve production efficiency. Practice has proved that the three-dimensional software-assisted staking out method has the advantages of accurate design, quick operation and easy modification as compared with the traditional method of setting out of sheet metal.
