Method for the production of a hollow profile provided with a terminal lid, and jack console

Abstract

The invention relates to a process for producing a hollow profiled section (7) with bulges (37) which is provided with an end-side closure cover (7), and to a jack bracket (32) produced by means of this process. To allow simple production of an expanded hollow profiled section (6) provided with a closure cover (7) and to demonstrate a jack bracket (32) produced by this process which entails only a low level of manufacturing outlay yet nevertheless ensures a high ability to withstand mechanical stresses, it is proposed that a cup-like cover (7) be pushed into the hollow profiled section (6), with the hollow profiled section (6) being placed into a hydroforming die (1). After the latter has then been closed, an axial ram (8) is introduced into the cover (7) and into the end of the hollow profiled section, in such a manner that the rim side of the cover (7) is radially pressed to the surrounding hollow profiled section (6). The hollow profiled section (6) is then widened by means of hydroforming pressure.
