Abstract
1,248,253. Stamping; working at specified temperatures. PRESSED STEEL FISHER Ltd. 14 March,. 1969 [21 March, 1968], No. 13678/68. Headings B3Q and B3V. A superplastic metal alloy is heated after it has been hot formed to a temperature above the range at which it exhibits superplasticity before it is stripped from the forming tool. In one embodiment, Fig. 1, electrical heaters 18 are positioned to heat a eutectoid Zn-Al superplastic alloy blank 15 to and maintain it at 275‹ C., whereupon it is vacuum formed against the die 12. After forming, the temperature of the blank 15 is raised by the heaters 18 to 310‹ C. and the formed blank stripped from the die 12 by a blast of compressed air. In another embodiment (Fig. 2, not shown), the blank (33) is clamped between sealing rings (26, 29) and heated to 250‹ C. by electrical heaters (32) mounted in a pressure box (28) and heaters (25) embedded in a porous refractory die (24). The blank is formed against the die (24) by passing compressed air through the pressure box (28), after which it is heated to 310‹ C. and finally, stripped by pin ejectors (not shown).
