发明名称 METHOD AND DEVICE FOR PRESSING METAL SHEET MATERIALS
摘要 <p>The device has base and outer (11) and inner (12) slides and including a basic die (15,16,17,18) mountable to the press and tooling (25,51) mountable to the basic die. The basic die includes an upper shoe (15) mountable to the outer slide (11), and hydraulic cylinder assemblies (17,18) mounted on the base and actuable by the inner slide for providing pressurised fluid to the tooling. The tooling includes upper and lower dies (51,25) connected to the upper shoe (15) and base. A blank (80) is positioned upon the lower die (25), and the upper die (51) is moved to a closed position by the outer slide (11). The blank (8) is clamped by gripepr steels (75) located in the upper die (51).</p>
