Abstract
1,058,370. Stamping. R. J. REYNOLDS TOBACCO CO. Sept. 17, 1965 [Sept. 21, 1964], No. 39772/65. Heading B3Q. A method of drawing sheet aluminium &c. (11) into a die (12), Figs. 3, 4, 6 and 7 (not shown), comprises two stages, in the first (Fig. 3) a hold-down (38) allowing lateral movement of the clamped margin of the sheet, and in the second (Fig. 4) the margin being securely held. In a first embodiment the die (12) is raised hydraulically against a fixed punch until, at the end of the first stage, the hold-down (38) engages the punch-base (40b). The second stage is effected by compressed air, supplied through a passage (46), with the margin firmly clamped. The die-chamber, beneath the sheet, may be evacuated. In a second embodiment (Fig. 6), the sheet is lightly clamped in a press between the die (50) and a hold-down (56) while compressed-air is admitted for the first stage, during which the margin slips. Clamping pressure is increased for the second stage (Fig. 7), during which the drawing operation is completed by increasing the pressure of the compressed air.
