Abstract
In the automotive industry is an increasing demand on closely-tolerated complex functional components with variants due to ecological and economic challenges. As current forming processes are often limited, a promising approach to fulfill these requirements is the combination of traditional sheet and bulk metal forming processes. In investigations on a combination of deep drawing and upsetting, this topic is researched fundamentally. In this forming sequence a base body is formed by deep drawing, whereas gear teeth are upset at the pre-formed cup. The paper discusses the influence of the blank thickness on forming forces and component properties. Furthermore, the approach of local adapted tribological conditions to reduce the press forces is investigated.
