| Abstract: | With the widely application of the forming technology,controlling of the drawing quality of the sheet metal has been becoming the focus of the stamping technology.Taking the cup part drawing as an example,by the aid of the finite element method software Dynaform,numerical simulations on different variable blank holder force load curves have been carried out with CAE.At last,find the appropriate optional load curve of a cup part drawing.Results are also validated by simulation tests.The drawing performance could be greatly improved. |
