Apparatus and method for hydroforming sheet metal

摘要: Apparatus for forming sheet metal blanks (80) within a press (10) having base and outer (11) inner (12) slides including basic die (15, 16, 17, 18) mountable to the tooling (25, 51) die. The includes an upper shoe (15) slide (11), hydraulic cylinder assemblies (17, mounted on actuatable by providing pressurized fluid tooling. lower dies (51, 25) connected base. A blank is positioned upon (25) (51) moved closed position (8) clamped gripper steels (75) located in (51). dwells while moves down, actuating 18), causing be forced between 100 % stretch form into
