摘要： Methods and devices provide for high velocity forming of medical device casings. The high velocity forming may be produced by creating a pressure wave within a liquid contained by an enclosure. A die and a workpiece adjacent to the die are in the path of the pressure wave within the enclosure and the pressure wave forces the workpiece to conform to the contours of the die. Objects may be adhered to the die to provide for customized contours. Trimming features may be included within the enclosure to trim excess material from a formed workpiece as an integral part of the forming process. Various other features may also be provided within the enclosure including a diffuser to disperse the pressure wave. The workpiece may be of various forms including flat sheet stock.

摘要： An electromagnetic forming device for a sheet of material is provided. The electromagnetic forming device includes a fixing base, a magnetic concentration block, an electromagnetic actuator, and a die. The fixing base has a groove. The magnetic concentration block is disposed in the groove of the fixing base, and has an accommodating space therein, which is in communication with a surface of the magnetic concentration block via a slit. The electromagnetic actuator, used to generate a magnetic field, is disposed in the accommodating space of the magnetic concentration block, but does not contact the magnetic concentration block. The die and the magnetic concentration block are separated by a gap, and a sheet of material can be disposed in the gap. As the magnetic concentration block is a block, eddy currents in the magnetic concentration block are distributed uniformly, so the generated magnetic field is also distributed uniformly, thus exerting a uniform forming force on the sheet of material.

摘要： A press (10) for operating a tooling unit in the performance of a manufacturing operation, such as crimping terminals onto a conductor. The press is adapted for attachment to the frame of a host machine (12), such as a lead maker, and for receiving a tooling unit, such as a terminal applicator (52). The press (10) includes a frame (13), a carriage (20) arranged for reciprocating motion with respect to the frame (13) and a ram (110) in sliding engagement with and carried by the carriage (20). A relatively low powered actuator (22) causes the ram (100) to move through a first incremental amount of movement during the first portion of the crimp cycle and a second, more powerful, actuator (80) causes the carriage (20) and ream (110) assembly to move through a second incremental amount of movement to complete the crimp cycle.
