Abstract:
A roof assembly for a vehicle that includes a center roof panel made from a lightweight material like aluminum, a surrounding attachment flange made from a more formable and stronger material like steel, and a junction that connects the roof panel and the attachment flange together. The aluminum-based roof panel may reduce the overall weight of the assembly, while the steel-based attachment flange may improve its metal forming and attachment capabilities.

Abstract:
A system is provided. The system comprises a first computer located in a first plant, a first memory, and a first object based process management application stored in the first memory. The system further comprises a second computer located in a location separate from the first plant, a second memory, and a second object based process management application stored in the second memory. When executed on the first computer, the first application invokes scripts in response to events and the scripts launch tasks. When executed on the second computer, the second computer invokes scripts in response to events and the scripts launch tasks, one of the events acted on by the second application is a message received from the first application.

A system is provided. The system comprises a computer system, an at least one memory; and a first application stored in the at least one memory. When executed by the computer system, the first application automatically executes a workflow that receives a first input from a human machine interface (HMI) in a first plant, in response to the first input generates a first event that assigns a first task associated to a first functional role performed at the first plant, receives a second input associated with the first task, in response to the second input generates a second event that assigns a second task associated to a second functional role, receives a third input associated with the second task, in response to the third input transmits information to the human machine interface that changes the process mediated by the human machine interface in the first plant.
Abstract:
A clamp assembly for a hydroforming die includes a stationary lower bed to support a lower die half of the hydroforming die, a stationary upper bed spaced above the lower bed, at least one guide post extending between the lower bed and the upper bed, a movable slide disposed between the upper bed and the lower bed and movable along the at least one guide post to support an upper die half of the hydroforming die, a lifting cylinder operatively connected to the movable slide to move the movable slide and upper die half toward and away relative to the lower die half, at least one link mechanism connected to the upper bed and the movable slide to equalize a force on the hydroforming die, and at least one linkage cylinder operatively connected to the at least one link mechanism to activate the at least one link mechanism to prevent the movable slide and upper die half from moving away from the lower die half to keep the hydroforming die closed during a hydroforming process.
Abstract:
An apparatus for in-die piercing of a tube as it is hydroformed creates a sharp edged, non countersunk hole, while sealing against pressurized fluid loss and ejecting the slug cleanly from the apparatus. A sharp edged die button inset into one of a pair of die blocks includes a hole shaped cutting edge surrounded by a compliant face seal flush with the cavity between the die blocks. A plunger is slidable within a central bore in the die button from a closed position flush with the cutting edge to a partially retracted pierce position, and finally to a further retracted ejection position. An ejection chute in the same die block opens into the bore at one end, at a point between the pierce and ejection positions of the plunger, and also opens at the other end out of the die block. The plunger is sealed relative to the die button bore. The plunger is retained in closed position until the tube is fully hydroformed to final shape, and the outer surface of the tube engages the face seal. Then, the plunger is retracted to pierce position, allowing a slug to be blown out through the cutting edge. The face seal and plunger seal prevent the loss of fluid. Then, the tube is de pressurized, and the plunger retracts farther, allowing the slug to be ejected.
Abstract:
A seal device for a hydroforming press includes a housing having a bore and a seal carrier slidable within the housing bore. The seal carrier has a bore which fits closely outside of the end of tube to be hydroformed. A V-shaped locator rigidly mounted relative to the housing aligns the end of the tube placed thereon with the carrier bore. A carrier actuator is operable to move the seal carrier between a retracted position away from the end of the tube to an extended position over the end of the tube. A resilient elastomeric annular seal carried by the seal carrier encircles the outer surface of the tube. A seal actuator carried on the seal carrier compresses the seal upon relative movement between the seal actuator and the seal carrier. A stop is engaged by the seal actuator as the seal carrier approaches the extended position so that subsequent further movement of the seal carrier compresses the seal against the tube. The locator and a tube backup fixed to an upper bed of the press encircle the tube when the press is closed, reacting against the tube when it is pressurized. A travel limit block provides a reaction member against which the locator reacts to prevent relative movement between the seal device and the press during forming.
Abstract:
A joining operation for a stack of three metal sheets performed using only a single welding step, with access to only one sheet side being required. An inner sheet of the stack has formed therein a pair of bifurcated projections, wherein at least one first apex faces in one direction and at least one second apex faces in the opposite direction. First and second outer metal sheets are assembled with the inner sheet, wherein the first outer sheet abuts the at least one first apex, and the second outer sheet abuts the at least one second apex. A projection welding apparatus welds the sheets, using only access to the first outer sheet superposed the bifurcated projections, wherein a majority of the current flows through the second outer sheet.

Abstract:
An apparatus and method for locally expanding tubular member includes a pre-form die having a cavity with an expansion chamber therein to receive a portion of a tubular blank between ends thereof. The apparatus also includes a bladder apparatus for insertion in the tubular blank and cooperating with the pre-form die to locally expand the portion of the tubular blank in the expansion chamber to form a locally expanded tubular member.
