  • Patent number: 10882098
    Abstract: A method of processing a material by use of high kinetic energy comprises a piston driven from a start position by a hydraulic system pressure by a drive chamber, by only one stroke, to transfer high kinetic energy to a blank/tool to be processed, whereafter there is a risk that a rebound of the piston will occur, so a step is taken in connection with said stroke performed, to prevent said piston from making a rebound with an essential content of kinetic energy to avoid negative effects as a result, whereafter the piston is returned to said start position by means of a second chamber, wherein a valve means closes the driving connection between the system pressure and the piston, the valve means is controlled by a pilot valve controlling the entire striking progress, and the second chamber is pressurized with the system pressure during the entire striking progress.

    Abstract: A manufacturing method forms components having a desired shape. A contoured surface is defined for a forming tool for forming a metal blank into the desired shape, wherein respective portions of the metal blank flow over the contoured surface during forming. An intrinsic material flow pattern resulting from the contoured surface is compared to a desired flow in order to identify regions of the contoured surface having an insufficient flow that creates areas in the formed metal blank receiving less than a desired amount of metal. A surface microtexture is applied onto the contoured surface in a pattern selected to increase metal flow along the identified regions by providing a friction in the identified regions that is reduced relative to adjacent regions of the contoured surface.

  • Patent number: 8423191
    Abstract: A cast iron brake caliper with improved fatigue life, and a process and process equipment for pre-stressing a cast iron brake caliper to provide improved fatigue life, is provided. In the process, a load is applied to a cast iron caliper, where the load is high enough to locally yield and plastically deform the cast iron material, but not high enough to cause material failure, such as cracking. Upon load removal, residual compressive stresses in the cast iron caliper lower the mid-point of the stress range the plastically-deformed region of the caliper sees during in-service use, and thereby lowers the peak stress seen in this region, increasing fatigue life. The process permits a cast iron brake caliper to be designed to use less material and thus fit within constrained wheel rim envelopes, without the need to resort to high cost materials or other alternative design strategies.

  • Patent number: 8352064
    Abstract: A revert alloy is used in the manufacture of a target alloy having a different composition. The weight percent of the elemental constituents of this first alloy and a second or target alloy are obtained, and the ratio of the percentage by weight of each elemental constituent in the first alloy to the second alloy is determined. The lowest ratio is used to determine the amount of the first alloy that is melted and the necessary elemental constituents that are added to the melt to produce the desired composition of the target alloy. The melt is solidified to produce the target alloy.

  • Patent number: 8280531
    Abstract: A method and computer program for the control of the heat treatment of batches of metal workpieces for increasing the degree of automation of industrial furnace plants presumes an identical batch layout, an identical treatment program, and an identical article geometry of metal workpieces and relates it to a model batch, which has been run using batch thermoelements. The model batch becomes the foundation for a new batch. Through the assumption of program parameters of the actually run process of the model batch into the program of the new batch to be run, new batch thermoelements are not required for the new batch to be run.

  • Patent number: 8214182
    Abstract: Computational systems, methods, and articles of manufacture to predict at least one of residual stresses and distortion in quenched aluminum castings. Residual stresses and distortion may be predicted through incorporating thermal strains induced during quenching with the nonlinear constitutive behavior of quenched microstructures of a quenched aluminum casting, wherein thermal strains arise generally from non-uniform transient temperature distribution of the casting during quenching. The transient temperature distribution of the aluminum casting during quenching may be calculated based on heat transfer coefficients specific to one or more nodes, elements and/or zones on the surfaces of the aluminum casting. The nonlinear constitutive behavior of the quenched aluminum casting may be modeled as functions of temperatures, strain rates, and microstructure variations. A material constitutive model accounts for not only strain hardening and creep, but also precipitate hardening.
