Abstract:
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.
Abstract:
An apparatus and method to cradle and hem panels at an assembly-line station. A cradle assembly is configured to conform to the shape of a first sheet material and prevents deformation of the class-a surfaces. A first robotic arm operatively associated with said cradle assembly and a slide-assist assembly cooperate to stabilize the cradle and secure a cradle anvil against the first sheet material. A roller head for hemming said first sheet material supported on a second robotic arm. The second robotic arm moves the roller head around the periphery of the first sheet material and against the cradle anvil to form a hem.

Abstract:
The present invention relates to an improved resistance weld-based gun assembly for use in an electric welding system without a need for plant-provided air and water-cooling circulation systems. In one aspect of the invention, a resistance-based force controller measures the resistance of a secondary circuit of the weld gun, the combined resistance of the secondary circuit in parallel with the circuit formed by the workpieces and opposing electrodes when sandwiched between the electrodes, and calculates the resistance of the workpieces. The measured resistance is compared to a predetermined resistance and the sandwiching force of the electrodes incrementally adjusted until the resistance of the workpieces is acceptable. The invention also relates to a closed loop coolant system having a coolant line, a coolant contained within the coolant line, a heat exchanger, and a mechanical coolant pump. One possible pump comprises an elastic bladder dependent upon the state change of the coolant. A second possible pump comprises a reciprocating extractor mechanically connected to the weld gun actuator. In yet another aspect of the invention, the welding system relies solely on electrode arm material for heat dissipation, the heat being conducted through the electrode arm material to an outer surface of the arm where the heat is dissipated through natural convection. To promote natural convection, a plurality of ribs with channels defined therebetween or openings extending through the arm itself increase the surface area and the rate of convection.
