| 摘 要： | 研究了板料数控渐进成形变形力的2种计算方法:按照纯剪切变形的方式计算变形力;按照剪切和弯曲综合变形的方式计算变形力。同时,通过实验测量出渐进成形的实际变形力。通过比较,实验测定的变形力与假定剪切弯曲变形计算的变形力相近,可以认为渐进成形是一种剪切弯曲变形。

| Abstract: | NC incremental sheet metal forming force is an important process parameter. It is studied by shear deformation and shear-bending deformation. The true forming force is measured by experiment. By comparison, the result is very close. A conclusion is drawn that NC incremental sheet metal forming process is a shear-bending deformation. This is a convincing basis for equipment selection and forming mechanism. |
