Abstract

Automation lines used widely in sheet stamping industry, which can stamp the part with higher stroke rates. Die temperature may rise for the deformation and frictional induced heat, which can trigger the crack or wrinkle of part, thus make the automation line unstable. Simulation techniques of multi-strokes stamping with high stroke rates is studied. Strain rate and temperature-dependent material properties, thermal properties of the blank and die components, sliding velocity, pressure and temperature-dependent friction coefficient etc. is incorporated in the simulation model. A secondary development software is developed to trigger the commercial software running and reading the calculate results. It can run multi-strokes simulation and save the required results. Simulation of a tube deep drawing with 100 strokes is carried out. The die temperature rise curve is obtained. And the thickness change in different strokes is compared. It showed the crack or wrinkle risk is changed for the die temperature rise. Method to decrease the failure risk is studied based on the simulation result, adjust the blank holding force or control the die temperature by cooling method can make the automation line more stable.
