Abstract
20,943. Eckstein, H. A. Oct. 19. Metal pipes and tubes are produced from flat plates by a forging and swaging process. Dies a, b, in two or more parts, and formed as shown, are used in a forging-press, to convert a flat plate g into a tubular form. The plate is held concentrically by mandrels l, m, and is successively converted by the conical portion c, d of the dies into the forms h, i, k, Fig. 1. The gradually-diminishing portions e,f of the die then swage the dished blank into a tubular form, as shown in Fig. 3.
