Abstract Scope |
In deep drawing processes, drawbeads are frequently used to control material flow while forming. It is well-known, that material parameters are changed significantly after a drawbead passage. Also, there are many references that the tribological system after a drawbead is changed and that this has influences on the ongoing forming process.
In this study, the connection between work hardening and the tribological system after a drawbead is analyzed with respect to the initial state. Therefore, sheets are drawn through a gap controlled drawbead passage while parameters like the gap between blank holder and die or the materials are varied. Afterwards, hardness measurements will be carried out as well as 3D surface measurements to correlate them. For these investigations, three different sheet metals are used: a conventional deep drawing steel, an advanced high strength steel AHSS and an aluminum alloy, as they represent the variety of industrial used sheet metal. |
