THE WALL DEFORMATION AND THE DIAMETER REDUCTION IN THE PROCESS OF TUBE DRAWING WITH A FLOATING PLUG

摘要

The existing methods of analysis of drawing with a floating plug stated the most favourable angle differences between the drawing die and the plug. In the paper the theoretical analysis is made enabling achieving the possibly minimal diameter reduction at the stated wall thickness reduction. There is discussed tool geometry and a state of stress, which enable stable guidance of the process. The experimental studies with drawing of OF-Cu copper and CuZn37 brass tubes confirmed the results of theoretical consideration.
