    摘要: Die vorliegende Erfindung betrifft eine Umformvorrichtung (90) sowie ein Verfahren zum Umformen eines Ausgangsteils (38) in einen Hohlkörper (50), die einen Halsteil (46) sowie einen sich daran anschließenden und sich ausgehend vom Halsteil erweiternden Schulterabschnitt (70) aufweist. Der Hohlkörper (50)dient beispielsweise zur Herstellung von Aerosolflaschen oder Getränkeflaschen aus einem metallischen Material, bspw. Aluminium oder Weißblech. Zunächst wird in einem ersten Umformschritt U1 ein topfförmiges Ausgangsteil (38) umgeformt, um an einem axialen Ende den einseitig geschlossenen, hohlzylindrischen Halsteil sowie eine den Halsteil koaxial umschließende Zwischenwand (47) zu formen, die koaxial von einer hohlzylindrischen Wand (39) umschlossen sind. In einem zweiten Umformschritt wird der Halsteil (46) gegenüber der hohlzylindrischen Wand (39) verschoben, so dass sich die Zwischenwand zu einem Schulterabschnitt (70) umformt.

    摘要: A can end blank (S) is initially cupped and a central portion of the cup is rolled up with an annular portion of the cup being free formed with limited contact with any tooling except to prevent wrinkling, to prevent overextension of the free formed material and to define a final geometry of the free formed material as the forming press reaches a bottom of its forming stroke. The free forming is performed by controlling the motion of a pre-panel punch (118) using a double action piston (123) so that the pre-panel punch (118) is selectively moved between an extended position for formation of a cup of a cupped can end blank (114) and a retracted position for free forming material between a central portion of the cup (106C) and a clamped portion of the cupped can end blank (124).

    摘要: An apparatus and method for forming a narrow, tightly radiused annular anti-peaking bead in a can end in a multi-station conversion press. In a first forming station, a metal blank is first drawn into a cup shaped blank having a side panel and then reformed by reversing the action of the drawing tooling so as to fold the side panel into an initial, relatively broad annular bead. The initially beaded can end is then transferred to a second forming station where its periphery is pre-curled and the annular bead is reworked so as to reduce its width and radii of curvature. The reworking of the bead is performed by free drawing a tool over the inner wall of the bead without drawing or bending the interior surface of the bead around a tool so as to avoid cracking or excessive thinning of the metal. The seaming panel of the can end is firmly clamped during the reworking to maintain control over the location of the bead. The can end having the reworked bead is then transferred to a third forming station for final curling of the seaming panel.

    摘要: The present invention relates to a stud and a method of fabricating the same, in which a female screw portion of the stud is formed in a cup shape by means of a reverse drawing process, thereby preventing damage of the female screw portion due to vibration and torque and solving a problem of quality degradation of various electronic products due to generation of burrs. The present invention comprises the steps of performing a deep drawing on a metal plate at a round shaped blank into a cup-shaped blank to thereby form a flange portion; performing a plurality of drawing processes again for reducing a diameter of the cup-shaped blank to thereby complete a body portion; performing a reverse drawing to form a female screw portion at the body portion; forming a press-fit fastening groove at a contact surface of the body portion and the flange portion by means of a slitting process, and performing a trimming process to fabricate the stud.

    摘要: The invention relates to a method for operating a forming press, in which a workpiece (2) in a rigid press frame (1) is pretensioned against a tool (3), using a clamping force Fnh. At least one piston tool (4) applies an impact force Fst parallel to the clamping force Fnh. Closing cylinder forces Fsz are applied in opposition to the impact force Fst and the clamping force Fnh and a water reservoir (5) is configured in the tool (3) which allows corresponding forces p*A to be exerted on the workpiece (2). The method is characterised in that the interfering force which results from the application of the impact force Fst is determined and compensated by a modification of the closing cylinder forces Fsz.

    摘要: The invention relates to a method for deep-drawing cavities (2) in thin metal foils (3), preferably in aluminium composite foils coated on both sides with a plastic material and used for blister packs (1). According to said method a drawing punch (6) pushes the metal foil (3), which lies flat between the blank holder (10) and the lower die (12), into a die opening (13). To optimise both production and the shape of the cavity the invention provides for a subsequent deformation step, according to which the casing wall (19) extending from the floor to the level metal foil area is encircled in a circular manner by a second die opening (18) with a resulting reduction in the diameter of the cavity opening (D to D') and displaced inwards towards the drawing punch axis (x-x), i.e. at a steeper incline to the level metal foil plane (E-E).
