摘要： The basic invention relates, in particular, to a forging hammer, comprising an electric linear drive, having a linear rotor and a ram that is coupled to the latter for the purpose of executing forging motions, wherein the linear rotor and the ram are connected to each other through an interposed flexurally elastic decoupling structure that acts between the linear rotor and the ram, and the decoupling structure is realized and arranged to decouple the linear rotor, at least partly, from relative motions of the ram relative to the linear rotor that occur during a forging motion.

摘要： A ram assembly for an electromagnetic work tool which includes a ram shaft, conductive driving plate, and insulator plug, which elements are bonded together to form an integral ram assembly thereby reducing shear stress on the insulator plug since no counterbores or screws are utilized in the ram assembly. The insulator plug utilizes a composite of unidirectional glass fibers in an epoxy matrix, which glass fibers are oriented parallel to the axis of the ram shaft thereby providing superior load distribution of the insulator plug. A reduced number of interfaces in the ram assembly provides less interfaces for reflection of shock waves.

摘要： An opposed current flow magnetic pulse forming and joining system in electrical communication with a magnetic pulse power supply having a positive connection and a negative connection. The system may be used in forming individual workpieces or joining multiple workpieces, including joining by magnetic pulse welding. The system includes a first section, a second section, an insulator, and a first and a second pair of conductors. The first and second sections cooperate to enclose the workpiece(s) and function to create an electromagnetic force similar to that produced by a single closed coil. The system is configured to achieve desirable current flow by minimizing inductance, inductive reactance, and impedance in the conductors. The pairs of conductors may incorporate closely spaced individual conductors, braided conductors, and coaxial conductors. The current flow in the individual conductors of each pair of conductors is opposed, as is the current flow through the sections.

摘要： Method for forming or deforming a metal workpiece by passing a stress wave through the metal workpiece sufficient to render it momentarily plastic. The apparatus is basically comprised of a stress wave focusing device or amplifier. In operation, a workpiece is placed in a die or shaping means. The stress wave amplifier is then arranged to direct or focus the stress wave to the metal workpiece. Next, a stress wave is generated and passed through the stress wave focusing device, imparting a momentary state of plasticity to the metal workpiece.
