Abstract

The current economic and ecological trend towards lightweight construction and functional integration is constantly increasing. In order to produce components with near-net-shape geometries in an eco-friendly process, forging is the ideal solution. The Sheet-Bulk metal forming (SBMF) process, which combines the benefits of both sheet metal and bulk metal forming, is an advantage in this context. To accurately replicate numerical simulation models as realistically as possible, it is essential to make adjustments to the parameters. Especially friction that occurs between the tool and the workpiece plays a critical role. It can affect the material flow as well as tool wear and product quality. Various methods can be employed to determine the friction factor, such as the ring compression test or the pin extrusion test. Both are suitable for investigating the tribological conditions in the SMBF. As the pin extrusion test is a full forward extrusion process that produces a pin, this process is suitable for the procedure to be used in the following studies. The objective of this research is to quantify the effects on friction by systematically varying modified parameters such as temperature, forming velocity and amount of lubricant, and integrate these findings into simulation models in the pin extrusion test. For this purpose, the pin extrusion test was first modeled numerically by using the simulation software Simufact.Forming. In order to validate the simulation model, experiments were conducted on a hydraulic deep-drawing press. The material DC04 was used for the drawing tests. It was possible to analyse the changes in the friction factor with additional influence on the manufactured geometry and its surface roughness.
