Computer controlled experimental device for investigations of tribological influences in sheet metal forming

1. Srbislav Aleksandrovic, Fakultet inženjerskih nauka Univerziteta u Kragujevcu, Serbia

Sheet metal forming, especially deep drawing process, is influenced by many factors. Blank holding force and drawbead displacement are two of them that can be controlled during the forming process.
For this purpose, electro-hydraulic computerized sheet-metal strip sliding device has been constructed. Basic characteristic of this device is realization of variable contact pressure and drawbead height as functions of time or stripe displacement. There are both, pressure and drawbead, ten linear and nonlinear functions. Additional features consist of the ability to measure drawing force, contact pressure, drawbead displacement etc.
Presented in the paper are the device overview and the first results of steel sheet stripe sliding tribological physical model.
