Device and method for opening folded heat exchanger cores

A device is configured for opening a heat exchanger core from a U-shape to a V-shape. Such heat exchanger core has a plurality of parallel flat tubes, each having two ends; and two manifolds. Each of the flat tubes has two straight sections adjacent to the manifolds and an intermediate bent section. The device has two hinged frames, a respective clamp arrangement on each of the hinged frames for holding the two manifolds, and a trough shaped support for the intermediate portion. For opening the U-shaped heat exchanger core, the heat exchanger core is inserted into the device, and the two manifolds are secured with the clamp arrangements. The clamp arrangements are separated from one another by pivoting apart the two hinged frames, on which the clamps are mounted. Simultaneously, the intermediate bent section is pushed toward the trough adapted to provide a desired curvature to the intermediate section.

REWORK PRESS ASSEMBLY FOR COMPONENT REWORK SYSTEMS AND METHODS OF USING THE SAME

A rework press assembly for reworking a dimensionally non-conformant component is provided. The rework press assembly includes a frame, a die coupled to the frame and configured to contact a first portion of the component, and a ram. The ram is coupled to the frame opposite the die with respect to an axis of the rework press assembly and is configured to contact a second portion of the component. The ram and the die define a component cavity therebetween. At least one of the die and the ram has a first length, relative to the axis, in response to the rework press assembly being at a first thermal condition. The at least one of the die and the ram has a second length, relative to the axis, in response to the rework press assembly being at a second thermal condition, and the second length is greater than the first length.

Method for Straightening of Radial Run-Out Faults or Linearity Faults on Elongate Workpieces, and Measuring Device, Straightening Machine, and Straightening System Thereof
20190210082 · 2019-07-11 ·

In the straightening of radial run-out faults or linearity faults on elongate workpieces having at least one toothed region having peaks and troughs of the teeth of said toothed region, such as on toothed shafts or toothed racks, for ascertaining deviations from the ideally straight workpiece, the locations of the surfaces of the not yet straightened workpiece that form a reference plane are scanned at least at points or in portions on or in the region on the active reference circle or pitch circle, respectively, of the toothing that lies between the peaks and troughs of the teeth. The resulting measured items of data are utilized by the straightening machine such that a workpiece that is as ideally straight as possible at least in the toothed region is achieved by the straightening. The elevated locations of the tooth heads of the toothed region that form the peaks of the teeth and the elevated locations of neighboring tooth surfaces that lie in the reference plane are detected, and the height differentials of the elevated locations of the tooth heads in relation to the elevated locations of neighboring tooth surfaces that lie in the reference plane are ascertained. The height differentials are utilized by the straightening machine as corrective measured items of data such that said height differentials are considered when straightening the workpiece so as to form a workpiece that is as ideally straight as possible in the reference plane.
