Abstract:An advanced technology of drawing in gas-storage cylinder making is presented. The cylinder body is made of cogged bloom by process of reshaping, piercing, backward drawing in vertical and finish rolling with newly designed hydropresses. Using developed 2-way cartridge valves the presses are controlled electrically. The technology may be useful to ferrous and non-ferrous industrial metal forming.

 

Key words: forging gas-storage cylinder drawing hydropress 2-way cartridge valve
