摘要： A method for forming a conduit with a radial flange for forming part of a beaded coupling by: positioning a conduit blank in a forming die, wherein the forming die defines a radially extending recess; inserting a forming post in the conduit blank to define an annular space therebetween; inserting a flexible material in the annular space between the post and the conduit; placing a sleeve in a bearing relationship with the flexible material; compressing the flexible material between the post and the sleeve to force the flexible material against the conduit to expand the conduit outward into engagement with the radially extending recess in the forming die to form an annular flange; and releasing compression on the flexible material.

摘要： A system for electro-hydraulically forming a sheet metal part in an electro-hydraulic forming (EHF) machine. The part in a first shape is placed in the EHF machine between a one-sided forming die and a chamber that is filled with a liquid. An electrode is discharged in the chamber to form the part toward the forming die. The electrode is advanced within the chamber toward the part and a subsequent discharge is provided in the chamber to form the part. A gap discharge EHF machine and a wire discharge EHF machine may be used in the system.

摘要： This aims to provide a press-apparatus mold capable of improving the yield of a blank while preventing wrinkles and cracks in a finished product, and an open-drawing method according to the press-apparatus mold. Within a range corresponding to the excess thickness portion (6) of a blank (4), the width of a punch (3) is gradually enlarged toward the end of the punch (3), thereby to curve boundaries (or the punch ridgelines (3d and 3e)) formed by the upper face (3a) and the side faces (3b and 3c) of the punch (3), toward the end of the punch (3) and to the widthwise outer sides of the punch (3). At the same time, the width of the recess (1a) of a die (1) is gradually enlarged toward the end of the recess (1a), thereby to curve a drawing profile (8) set by the punch (3) and the die (1), toward the ends of the punch (3) and the recess (1a) and to the widthwise outer sides of the punch (3) and the recess (1a).

摘要： A method of quick-plastic-forming a component from a sheet metal blank in multiple forming stages of single-action tooling along a transfer line. The blank is transferred from a prebending station to a preforming station along the transfer line, wherein the blank is preformed by a single-action forming tool into a preform blank. The preform blank is then transferred from the preforming station to a finish-forming station along the transfer line, wherein the blank is finish-formed by a single-action forming tool into the component. The component is transferred from the finish-forming station to a cooling station along the transfer line. The transfer steps are carried out by a reciprocating transfer mechanism that simultaneously transfers the blanks and component from station to station along the transfer line.

摘要： An apparatus and method for removing a part from a forming tool and supporting the part. The apparatus includes a support member having a surface contoured to conform to a formed shape of the part and an aperture disposed in the surface. A manipulator moves the support member near the part while the part contacts the forming tool. Pressurized gas is directed toward the part to cause the release of the part from the forming tool and to cool the part. The surface supports the part to inhibit distortion as the part cools.
