Abstract

1310549 Making valve bodies; forging TSENTRALNY NAUCHNO - ISSLEDOVATELSKY INSTITUT TEKHNOLOGII MASHINOSTROENIA 23 June 1970 30390/70 Headings B3A and B3H [Also in Division F2] A valve body or pipe coupling having a duct diameter greater than 250 mm. is made by forming two domed blanks by swaging so that at least one of them has a thicker central zone portion forming an inlet or outlet in the central zone portion and welding the two blanks together. In one embodiment, a drawn domed blank 29 having a central hole 30 is positioned on a swaging male punch 26 and a female die 24 lowered to swage the blank. Metal is displaced towards the hole 30 so as to form a reserve of metal for the subsequent shaping of the inlet or outlet in the blank. A punch 25 is then lowered to shape the inlet or outlet in the blank, the shaping operation causing a counter punch 28 to be depressed a short distance. The swaged blank is ejected by the counter punch 28. The valve body or coupling is finally formed by welding two swaged halves together. The domed halves may alternatively be swaged from tubular blanks (Figs.-11-13, not shown).
