    摘要: Systems and methods are presented for an improved high power density power adapter. On one potential embodiment, an improved power adapter includes an AC input; a rectifier coupled to the AC input; a power factor correction circuit coupled to the rectifier; and a burst switch circuit coupled to the power factor correction circuit. The burst switch circuit provides power to a DC output via a set of FET drivers, a set of FETs, and a transformer and may provides power exclusively in a burst mode using a feedback input from the DC output. The transformer may be composed of windings coupled to the set of FETs, and additional windings embedded in the PCB and coupled to the first winding. Certain windings may comprise a conductive ribbon that loops around a transformer core. Additional embodiments may include monitoring circuits and multiple outputs.

    摘要: A hemming machine for sheet metal is disclosed having a base adapted to be supported on a ground support surface. A cradle is vertically slidably mounted to the base while a nest is mounted to the cradle and adapted to support the part to be hemmed. Hemming tooling is mounted to the base and movable between an extended position in which the hemming tooling overlies the nest, and a retracted position in which the hemming tooling is spaced laterally outwardly from the nest. A pair of spaced ball screws are rotatably mounted to the base and threadably connected to the cradle on opposite sides of the nest so that rotation of the ball screws vertically displaces the cradle relative to the base. A single drive motor is drivingly connected through a two speed gear box to both ball screws to rotatably drive the ball screws in synchronism with each other.

    摘要: An inside perimeter hemming machine is disclosed having a base adapted to be supported by a ground surface. A nest adapted to support the part to be hemmed is vertically movably mounted relative to the base between predetermined vertical positions while at least one actuator vertically moves the nest relative to the base. A die assembly housing is mounted to the base, and this die assembly housing extends through the-opening on the part to be hemmed. At least two die sets are horizontally slidably mounted to the housing so that the die sets are movable between an extended and a retracted position. In their extended position, the die sets overlay the part to be hemmed so that, upon vertical displacement of the nest, a prehem or hem is performed. Conversely, when the die sets are in their retracted position, the nest together with the part to be hemmed is freely vertically movable. A wedge drive member is utilized to simultaneously move the die sets between their extended and retracted positions.

    摘要: A hemming machine having a stationary base and defining a work station. A lifting beam is vertically movably mounted to the base at the work station while a motor assembly moves the lifting beam between a raised and a lowered position. Two die cartridges, each having hemming tooling and a nest vertically movably mounted to the die cartridge, are horizontally movable relative to the base by a conveyor assembly. A conveyor motor selectively moves the die cartridges between a position laterally spaced from the work station and the work station. With the die cartridge positioned at the work station, a first clamp releasably secures the nest to the lifting beam while a second clamp assembly releasably secures the die cartridge to the base. With the nest secured to the lifting beam and the die cartridge secured to the base, hemming operations are performed at the work station in the conventional fashion.
