Abstract (en)
[origin: EP0649689A1] In a method for the production of press fittings, especially those made of copper, a blank (11) is held in a die (2), supported on the inner wall in the pipe connection region by means of a supporting mandrel and is then upset axially, the material of the blank being made to flow into an annular groove (7, 8) provided in the die and surrounding the pipe connection region to form a bead running around the outside. After the supporting mandrel (19) has been removed, an all-round bead is formed in the blank from the inside in the region of the annular groove, whereupon the finished press fitting is removed from the die. <IMAGE>
