Press for deep stamping metal can from blank

The deep stamping press produces flanged metal canisters (14) from flat blanks, using a sealed chamber (16) to isolate both the peripheral and central flange zones with the blank mounted on a matrix (3). Liquid under pressure is introduced into the chamber (16), and a varying pressure (q) is applied...

Zusammenfassung:The deep stamping press produces flanged metal canisters (14) from flat blanks, using a sealed chamber (16) to isolate both the peripheral and central flange zones with the blank mounted on a matrix (3). Liquid under pressure is introduced into the chamber (16), and a varying pressure (q) is applied to the flange rim during stamping. The pressure (q) is equated to a co-efficient which takes into account the average principle stress to which the blank is subj subjected. The matrix (3) and the clamp (7) may be contoured (13,15) to grip the blank and seal the compartment (16).
