摘要： A stock lifter for metal forming dies includes a self-contained assembly. The assembly includes a guide pin that reciprocates within a base. A hardened end cap, which contacts the stock, is attached to the guide pin. A spring is located on the exterior surface of a portion of the base and surrounds the guide pin body. One end of the spring contacts a surface on the cap, while the other end of the spring contacts a surface on the base or an optional mounting flange that is attached above the base. Thus, the stock lifter assembly has a hardened cap for the stock to slide on and a larger, externally mounted spring that provides longer life for the stock lifter. The stock lifter assembly can be made of several different lengths and sizes by using longer or wider guide pins and springs.

摘要： A forming tool for hot forming and partially press hardening a workpiece made of sheet steel comprising a die, a punch, and a cooling device. The die is formed of a first die part and at least one second die part which is movable relative to the first die part, while the punch is formed of a first punch part and at least one second punch part which is movable relative to the first punch part, the at least one movable second die part and the at least one movable second punch part interacting with an opening device which causes the at least one second die part and the at least one second punch part to contact the workpiece with a shorter closing time than the first die part and the first punch part.

摘要： A tool arrangement is disclosed for integration in a production line for producing a hot formed component from a blank which is produced from a hot forming steel strip. The tool arrangement includes a housing, which delimits an interior of the tool arrangement relative to a surroundings of the tool arrangement, a tempering station for tempering the blank and a hot forming station for hot forming the blank. The tempering station and the hot forming station are jointly arranged in the interior.

摘要： A bipolar plate having a surface structure for a flow field, inner forms such as holes and slots in the plate, and a reference geometry on the outer form thereof is produced by means of a hydraulic fine-blanking press having an at least three-stage progressive die, in the first stage of which a blank is cut partially free from a metal-foil strip, subsequently in a second stage the surface structure is formed in the connected blank via compression-forming using a forming force of at least 2500 to 3500 kN, the inner form, the slots and the reference geometry are formed by way of cutting in, and on, the blank and then, in a third stage, cutting of the outer contour and removal of the finished blank in the form of the bipolar plate are carried out successively in the stroke cycle.

摘要： A stock ejector assembly and method for metal forming dies includes a stock ejector with a large spring and a ring-style stripper. The ring-style stripper provides a larger surface area for contacting the stock. The large compression spring is preloaded and when a load is applied, the stripper retracts and the spring pressure increases. When the dies separate, the stock ejector pushes the part off flat surfaces, separating surfaces sealed by adhesion, including, but not limited to, oil or lubricant adhesion.

摘要： A pilot assembly and method has a cylindrical pilot sleeve with an apertured outer end in which a separate pilot pin is received, a grooved inner end, and a central portion with at least one inwardly curved sidewall relief, as well as internally mounted reciprocating ejector pins with outer ends that protrude through holes in the outer body end to strip stock from the pilot pin. A spring has its outer end mounted in the sleeve groove, and an inner end captured in a die pocket in a pretensed condition. A mounting screw has an enlarged head that has at least a portion thereof fit into the pilot sidewall relief, and a threaded shank that anchors the pilot sleeve in the die.
