  • Patent number: 8959971
    Abstract: A corner cam assembly for use with a forming die and including a generally cylindrical inner cam component, an outer cam component, a base, and a retainer unit. Contoured contact surfaces on the inner and outer cam components enable the components to slide past one another during transitions between retracted and extended positions. Some features of the corner cam assembly include helical contact surfaces, guide features that control movement of the cam components, removable work steels, standardized cam components, and being able to form negative and other tight angles, multiple corners and edges, to name but a few.

  • Patent number: 8104443
    Abstract: A helical cam device for use with a wide variety of applications generally includes a first cam component, a second cam component and an axial guide. The cam components each have a helical cam track located on an axial end, so that coaxial alignment of the two cam components allows opposing cam tracks to contact and rotate against each other. The helical cam tracks, which are preferably divided into quadrant sections, are designed such that relative rotational movement between the cam components causes a corresponding relative axial movement. According to one embodiment, the axial guide is a cylindrical rod passing through the center of the cam components; in another embodiment, it is a cylindrical sleeve surrounding the cam components. Moreover, barrel slots, detents and/or truncated peaks can be used to control the travel of the cam components.

  • Patent number: 7757533
    Abstract: A filler cam assembly for use with a forming die generally including a center cam component, end cam components and a base assembly and being designed to transition between unloading and forming positions. The various cam components preferably have axial ends with helical surfaces such that rotation of one of the cam components causes a corresponding axial movement of an adjacent cam component. Some features of the filler cam assembly include removable work steels, standardized cam components, drive and lock out mechanisms, and being able to form negative angles, multiple corners and edges, and an entire formable periphery of a metal work piece in a single forming operation, to name but a few.

  • Publication number: 20040078931
    Abstract: A door jig assembly for a vehicle, the vehicle having a door and an inner door jamb forming a part of a vehicle door frame. An arcuate bracket portion is fixedly secured to the inner door jamb. A coil spring member surrounds an intermediate extending location of the bracket portion, a first tab end of the coil spring biasingly engaging a location along the bracket portion and a second extending stem and passing through an aperture defined in the vehicle door. A collar secures to a further location of the bracket portion and exhibits a cam surface in abutting contact with an arcuate extending surface of the coil spring member. The coil spring member influences the door to remain in a first closed position, subsequent rotation of the door causing the spring to rotate about the cam surface to influence the door in an opposite and door open position.

  • Publication number: 20040060150
    Abstract: A door jig assembly for use with a vehicle, the vehicle including a door having an inner facing edge and which is hingedly connected to a vehicle pillar forming a part of a vehicle door frame. The door is further capable of being pivoted about the hinges and between opened and closed positions relative to the pillar. The jig assembly has an elongated body with a first end pivotally secured to the vehicle pillar. A pin pivotally secures to the inner facing edge of the vehicle door and translates in guided fashion in one of first and second directions along the elongated body and upon opening and closing the door. A spring biasing cage portion is disposed at an intermediate location along the elongated body and which, upon rotating the vehicle door to the closed position, establishes a specified holding force of the door against the vehicle frame.
