摘要： A hydraulic press comprises a lower cross-piece with a die and actuating cylinders mounted on the cross-piece. The piston rods of the cylinders are connected with an upper removable crosspiece by means of nuts of damping devices mounted in the upper cross-piece and the piston rods are articulated in the actuating cylinders serving at the same time as columns of the press. The surfaces of the rods are provided with screw threads and adjustable nuts are threaded therein to elevate the upper crosspiece and to ensure parallel arrangement of the cross-pieces at the end of the working operation of stamping. The lower crosspiece is mounted on bogies for lateral movement relative to the upper cross-piece.

摘要： A method and die set for stamping metal blanks into convex articles including positioning a blank between a punch and a ring-shaped die while clamping the edge of the blank, partially deforming the blank with the punch, and then forcing pressurized fluid between the punch and the partially deformed blank to form a convex article, while concurrently effecting controlled inward movement of the edge of the blank so as to control the thickness and quality thereof.
