    摘要： The invention relates to a tool (1) for cutting a hollow profile (2). According to the invention, the tool (1) is designed both for cutting a flange (3) on the hollow profile (2) as well as for deforming the hollow profile (2) according to the internal high-pressure deformation process. The tool (1) comprises at least one cutting device, which runs parallel to the longitudinal extension and which has a cutting edge (5) that can be displaced in a transverse direction of the hollow profile (2). A side (6) of the cutting device (4) facing the hollow profile (2) is provided in the form of a shaping matrix wall (17) against which the hollow profile (2) rests during the internal high-pressure deformation process. In addition, the tool (1) can have an stamping die (11) and a punching die (13), which is formed coaxially thereto whereby, in addition to the cutting and internal high-pressure deformation process, enabling an optional stamping and/or punching of the hollow profile (2).

    摘要： The invention relates to a tool (1) for the internal high pressure forming of a hollow section (2). According to the invention, said tool (1) is embodied in such a way that it can form the hollow section (2), emboss the outside of the hollow section (2), and also make a hole in the hollow section (2). To this end, the inventive tool (1) comprises an embossing die (11) that can be displaced transversally to the longitudinal extension of the hollow section (2), and a punching die (13) that is coaxially arranged in the embossing die (11).

    摘要： The invention relates to an internal high pressure forming installation (1) comprising a form tool (2) consisting of an upper die (3) and a lower die (4), the cavities (5) thereof forming a form chamber (6) for a peripherally closed hollow profiled element (7) to be inserted therein. Said installation (1) comprises at least one axial punch (8) which is used to seal the hollow profiled element (7) at one end (9) and comprises an axial through channel (10), by which means an internal high pressure can be produced by a pressurised fluid in the hollow profiled element (7) in order to enlarge the same. The inventive installation (1) also comprises a rapid filling device (11) provided with a filling attachment (12) with a filling borehole (13),(29) which has a diameter that is larger than that of the through channel (10) of the axial punch (8), and which is used to fill the hollow profiled element (7) with pressurised fluid when the axial punch (8) is set back from the respective hollow profiled end (9). The filling attachment (12) has a through borehole (14) that is penetrated by the axial punch (8) during the forming of the hollow profiled element (7). The aim of the invention is to be able to easily produce hollow profiled elements (7) formed by internal high pressure, on a large scale, by means of a rapid filling device (11) that is integrated into the installation (1) and is used to fill the hollow profiled element (7). To this end, the filling attachment is connected to a transport device that places the filling attachment (12) in a contact position on the form tool (2), and then in a position at a distance from the form tool after the filling process.
