| titleOfInvention | Method for producing a peripherally closed hollow profiled element |
| abstract | The invention relates to a method for producing a peripherally closed hollow profiled element by means of internal high-pressure forming. According to said method, a hollow longitudinal blank (5) is inserted into an internal high-pressure form tool (1) and, during the closing process of the form tool (1), the blank (5) which is fully inserted thereinto is compressed in a region between the two ends (9,10) thereof, whereafter the compressed blank (5) is enlarged into the end shape of the hollow profiled element by means of fluidic internal high pressure. The aim of the invention is to enable a reliable production of the hollow profiled element even in the event of large deformation of the hollow profiled blank (5) resulting during the closing of the form tool (1). To this end, the ends (9,10) of the blank (5) are cut before the compression process, respectively forming a bevelled front surface (12,13), and the cut contour of the ends (9,10) and the bevelling angle (.alpha.) are selected in such a way that the ends (9,10) are deformed by means of the compression process such that the front surfaces (12,13) thereof have an essentially plane form and assume a position that is as perpendicular as possible to the longitudinal extension of the blank (5). |
