Abstract

1,121,627. Cupping at specified temperatures. DORTMUND HORDER HUTTENUNION A.G. 30 March, 1967 [5 April, 1966], No. 14498/67. Headings B3Q and B3V. [Also in Division B5] In deep-drawing a laminated sheet 1, Fig. 1 (not shown), formed of two outer layers (2, 3) of metal, e.g. steel, and a central plastics layer (4) of polyvinyl acetate plasticized with tricresyl phosphate and containing a maleic acid ester as an adhesive, the operation is performed at 120-160‹ C. Passages 12, 14, 15 for circulating a liquid, vapour or gaseous heating medium may be provided in the drawing tools 5, 7, 8 or only in the die 5. The die surfaces are heated to 130-150‹ C., and the laminated sheet is heated in a furnace to 150‹ C. If the metal layers (2, 3) are of different thickness, the blank is so positioned that the thinner layer is on the outside of the drawn article. The holddown 8 may exert a pressure of 40-80 atmospheres. The gap b between the punch and die is greater than the sum of the thicknesses of the metal layers but less than the total thickness of the laminate.
