High-pressure tube hydroforming device for metallic pipes, has mechanism that has free projecting adapter stopper, and precisely fitting adaptation area that is formed between outer and inner extent surface

摘要

The device has an upper die (11) and a lower die (12) with dedicated outline in every case, a mechanism for the adaptation (13) of a pipe (14) which is deformed and a hydraulic pumping device. The mechanism has a receiving range for adaptation. The mechanism has a free projecting adapter stopper for adaptation in the receiving range. A precisely fitting adaptation area is formed, for receiving the pipe final range, between an outer extent surface and an inner extent surface. An independent claim is also included for a method for high-pressure tube hydroforming of metallic pipes, which involves inserting a deforming pipe into the device.
