<p>A die stamping system includes opposed die members (10, 11) which clamp a metal workpiece (W) to be shaped, cut or pierced after which the die members are moved away from one another and a part is subsequently ejected, wherein the ejector is controlled for a selected delay time by a plurality of cylinder assemblies (16) mounted in a manifold (17) so that they are connected to a fluid source of high pressure (53) and to a source of hydraulic pressure (53). Each cylinder assembly (16) includes a piston (26) associated with, and exposed to the fluid pressure in the manifold. The cylinder assemblies (16) are connected to a single hydraulic valve (50) which has associated therewith an accumulator (53) and which is operated simultaneously to actuate the cylinders. The hydraulic lines to the cylinders (16) are provided in the manifold (17).</p> |
