The Effects of Press Ram Vibrations on the Production Quality

authored by: Bernd-Arno Behrens, Kai Brunotte, Richard Krimm, Oliver Commichau
Abstract: An indicator for the quality of products that are formed in an embossing process is the contour of the product. Highest contour quality is achieved, if the shape of the forming tool is perfectly imprinted into the material. However, elastic forces and tribological effects, which occur during the forming process, impair the shape-setting progress. In order to improve the embossing process, 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 function of the actuators are presented in this paper. Experimental studies on an embossing process in a production environment were performed, to demonstrate the features of the novel system.
