|20140352392||TRIANGULAR HEMMING AND STAMPING APPARATUS - A triangular hemming and stamping apparatus includes a stationary base that mounts a lower die set. Three guide posts are triangularly positioned on the base and extend generally vertically from the base. An upper fixed superstructure is supported by the three guide posts and fixedly spaced from the base. An upper slidable structural member that mounts an upper die set is slidably mounted on the guide posts between the base and the superstructure. An actuator is mounted on the superstructure and connected to the upper slidable structural member within an area within the guide posts. The actuator is not connected to nor associated with the guide posts, and the actuator is operable to move the upper slidable structural member toward and away from the base to perform hemming and stamping on a workpiece.||12-04-2014|
|20140196516||ROTARY WHEELHOUSE ROLLER HEMMING ASSEMBLY - A rotary wheelhouse roller hemming apparatus in accordance with the present invention includes a support and a rotary mechanism including a plurality of connected anvils driveably rotatable about an axis. The rotary mechanism is mounted on the support. Rotation of the rotary mechanism about the axis moves the anvils between use and standby, non-use positions.||07-17-2014|
|20110048094||HORIZONTALLY STACKED HEMMING PRESS - A horizontally stacked hemming press includes a horizontally disposed base. A first vertical support is mounted on the base and disposed generally perpendicular to the base. A linear track is mounted on the base. A horizontally disposed die stack including a plurality of cooperably operable die sets are horizontally arranged in series and moveable along the linear track. Each die set includes a pair of vertically disposed die shoes. A guided press platen is horizontally moveable along the linear track. A second vertical support is mounted on the base distal from the first vertical support and disposed generally perpendicular to the base. A drive mechanism is supported by one of the supports and connected to the press platen for opening and closing the die sets. Actuation of the drive mechanism horizontally moves the press platen and thereby horizontally opens one of the die sets.||03-03-2011|
|20090235713||MAGNETICALLY ACTUATED ROLLER HEAD - A magnetically actuated roller head includes a linear actuator mountable on an end of a multi-axis robotic arm. The linear actuator includes a slide, a magnet operably connected to the slide and operable to urge the slide in a linear direction, and a connector disposed on a distal end of the slide. A roller hemming head is mounted on the linear actuator by the connector. The roller hemming head includes at least one hem roller.||09-24-2009|
|20090235712||INTEGRATED PUSH PULL ROLLER HEAD - A roller hemming apparatus includes a linear actuator mountable on an end of a multi-axis robotic arm. The linear actuator includes a connector. A roller hemming head is mounted on the linear actuator by the connector. The roller hemming head includes at least one hem roller. The roller hemming head performs both push force and pull force roller hemming operations.||09-24-2009|
|20090235505||HEM FLANGE CONTROL ROLLER - A method of roller hemming an inner panel and an outer panel includes providing a hem roller having an angled roller hemming surface, and adjusting a hem flange line by moving the hem roller axially and generally parallel to an anvil support surface.||09-24-2009|
|20090178458||TWO DIE PROCESS - A closure panel forming and assembly process includes inputting partially stamped inner and outer panels into the assembly system and finished assemblies out. The invention is a manufacturing process for closure panel assemblies, doors, deck lids, hoods, liftgates and other similar panels. The process has a reduced stamping operation of only two die stages, with the first operation being a draw operation followed by a second operation of trim and pierce. These operations may be done at a satellite location which may be within the same facility or at an outside location. All additional metal forming operations are done at an assembly system.||07-16-2009|
|20090126452||PART IN DIE, DIE CHANGE PROCESS - A die change method includes providing a press apparatus having a base and a ram, and a first die set including an upper die member and a lower die member. The lower die member is supported on the base and the upper die member is mounted on the ram. The ram is lowered into a closed, home position to mate the upper and lower die members and to perform an operation on a workpiece disposed between the die members. The ram is released from the upper die member. The ram is raised a minimum distance to provide minimal clearance for removing the upper and lower die members from the press. The mated upper and lower die members are moved out of the press with the workpiece held between the upper and lower die members.||05-21-2009|
