Review of research on sheet forming within the framework of realized projects of the Lukasiewicz Research Network - Metal Forming Institute

摘要

This article presents the scope of works performed at the Press Forming Department of the Lukasiewicz Research Network - Metal Forming Institute in recent years. It includes the results of tests, including statutory works, associated with spinning of axially asymmetrical products on the MWS-200 spinning lathe designed especially for this purpose by the Press Forming Department. Over the course of statutory works, numerical simulation software was used to assist and enable the performance of spinning tests. The results of works performed for industry, including: lighting, ventilation, automotive, aviation and food, are presented. Examples of products made using the spinning method are shown, including products made of perforated sheet, stainless steel and aluminum. Moreover, a machine intended for joining of ventilation elements was designed, made and implemented. During the period under discussion, the Press Forming Department participated in the realization of 8 EU and domestic projects, three of which are still underway. The scope of performed works concerned, among other things: rolling of flat bars with variable cross-section; hot-rolling of rings along with analysis of temperature distribution over the duration of the process; bending of extruded aluminum profiles with length up to 13 meters, made from 5xxx and 6xxx series alloys; cold rolling with the application of a heating and cooling system between cages of the rolling line; modernization of a special press for bonding of glass fiber belts with a width up to 2.5 m; bending of thin-walled profiles of variable cross-section with the application of local heating using a diode laser.
