Abstract (en)
[origin: EP2239132A1] The invention relates to plastic metal forming, in particular to pressing pipe-producing facilities. Said invention makes it possible to combine billet punching and pipe pressing operations into a single press operating cycle and to carry out operational punching and pressing strokes by means of a common drive, thereby reducing the number of the required processing facilities, simplifying the structural design, reducing the power, size and the mass of the press and decreasing investment costs.
