Correlation of die clearance value computed and experimentally determined during drawing of tinned sheet

Abstract

The aim of this study is calculation of die clearance from literature data followed by experimental verification on steel sheets. Steel sheet, thickness 0.24 mm. electroplated on both sides by tin with surface density 5.6/5.6 gm^-2 was selected. For experiments the drawing die was developed on TU of Brno. The uniformity of wall thickness of cylindrical shells without flange was measured on lines oriented 0°, 45°, and 90° with respect to the drawing direction. The results could be utilized in press shops.
