摘要
目前钣金制造企业中钣金件展开图绘制的方法为人工绘制,效率较低,且易出错误。通过分析90°角钣金件展开长度的计算方法,对SolidWorks软件自带的折弯表进行二次开发,使90°角钣金件模型通过加载二次开发折弯表可以实现1∶1准确展开。90°角钣金件展开后工程图可以保存为DXF文件,直接输入到数控塔冲、数控激光切割机中进行编程加工。
For factory on sheet metal,the efficiency for expanded view drawing of sheet metal is very low and easy to error. The bend table for SolidWorks is secondary on development,combined with calculation methods of neutral layer size when the sheet metal is expanded. The 90°angle of sheet metal can be expanded accurately with equal proportion by loading secondary development bend table. The expanded drawing can be saved for DXF file,which can be imputed to NC tower punching and NC laser beam cutting machine and can be machined according to programming processing.
