Apparatus and method for producing at least partially closed hollow profiles with a short cycle time

摘要

The invention relates to a device and a method for producing at least partially closed hollow profiles from a sheet by a U-O-forming with a tool set having a U-punch in a first tool half for producing an at least partially U-shaped sheet and an upper die in a second tool half for forming an at least partially U-shaped sheet into an at least partially closed hollow profile. Parts of the tool set run parallel to one another in the axial direction of the at least partially closed hollow profile to be produced and are arranged above one another in the closing direction of the tool halves, wherein a common matrix receiver is provided between the tool halves of the tool set, which receiver comprises at least two identical, partially U-shaped dies for the tool set and can rotate about its axial axis.
