| Abstract Scope |
An indicator for the quality of products that are formed in an embossing process is the product contour. Highest contour quality is achieved, if the shape of the forming tool is perfectly imprinted into the material. However, contact pressure and tribological effects, that occur during the forming process, produce tool wear and thus impair the shape setting progress.
To improve product quality, an electromagnetic actuation unit is presented in this paper, which applies horizontal vibrations into the press ram during the forming process. The actuation unit consists of two strong linear solenoids, which generate oscillating force with variable levels and frequencies. The vibrations improve the shape setting during the embossing process.
The concept, design and the functioning of the actuators are presented in this paper. Additionally, experimental studies on an embossing process in a production environment were performed to study the quality improvement by means of press ram vibrations. |
