TOOL AND METHOD FOR CUTTING A HOLLOW PROFILE |
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). |
