  • Patent number: 9003857
    Abstract: A current density changing portion is formed in a heating process on an upper base side with respect to a center portion of a flat metal plate in a direction of current flow, by passing current from a lower base side to the upper base side of the flat metal plate which is rectangular when viewed from above. As a result, a quenchable portion is formed on the upper base side with respect to the center portion of the flat metal plate in the direction of current flow, and a non-quenchable portion is formed on the lower base side with respect to the center portion of the flat metal plate in the direction of current flow. The flat metal plate is press-formed after the heating process, so a complex die cooling structure is not necessary during press-forming, which enables the die cost to be reduced.

  • Publication number: 20150069772
    Abstract: A bumper reinforcement is formed of a 7000 series aluminum alloy hollow extrusion and has crushed end portions. A portion of the end portions is heated to a temperature of 400° C. or more for reversion treatment, the heated portion is subjected to cold crushing, and then the whole bumper reinforcement is subjected to age hardening. Because of the age hardening, the heated portion has higher Vickers hardness than non-heated portions by Hv 10 or more. This compensates for a decrease in reaction force in a collision of an end portion resulting from a decrease in the section modulus of the crushed portion and thereby suppresses a decrease in energy absorption.

    Abstract: A method for locking a nut with an inner thread, in which the ultimate tensile strength (Rm) and yield strength (Re) of the material constituting the nut are determined according to temperature. An optimal heating temperature is determined, at which a maximum of a relative plastic interval of the material is reached, said relative plastic interval being defined by the formula (Rm?Re)/Rm, and a maximum heating time is determined, above which the nut presents the risk of deterioration of its microstructure and/or of its initial mechanical strength. The nut is heated to a temperature substantially equal to said optimal temperature and for a heating time of less than said maximum time so that the initial microstructure and mechanical strength of the material constituting the nut are preserved, and a body of the nut is deformed locally by bending.

    Abstract: The invention relates to a method that is used to produce a press-hardened molded part (3) having at least two regions that differ regarding the strength of the regions by means of a press-hardening tool. A blank heated to a forming temperature is formed in the press-hardening tool and held in the press-hardening tool during the cooling for the purpose of heat-treating. In order to set the regions of lower strength, said regions are cooled more slowly than the other regions. During the forming step, the entire blank and thus also the regions of the blank intended to be set to a lower strength are in contact with a molding surface of the tool (1). After the conclusion of the forming step, the tool surface (2) in contact with the molded part is changed in such a way that the one or more regions to be set with lower strength have no tool contact during the cooling step that follows the forming step.

    Abstract: A robotic bending apparatus for bending archwires and other types of elongate, bendable medical devices into a desired configuration includes a first gripping tool and a moveable gripping tool. The first gripping tool can be either fixed with respect to a base or table for the robot or positioned at the end of robot am. The moveable gripping tool is mounted to the end of a moveable robot arm having a proximal portion also mounted to the base. The robot preferably comprises a six axis bending robot, in which the distal end of the moveable arm can move relative to the fixed gripping tool about three translational axes and three rotational axes. The gripping tools preferably incorporate force sensors which are used to determine overbends needed to get the desired final shape of the archwire. The robot may also include a resistive heating system in which current flows through the wire while the wire is held in a bent condition to heat the wire and thereby retain the bent shape of the wire.

The metallic reflector device includes a planar base and a plurality of the reflector elements. The planar base has one or a plurality of apertures, each aperture having an edge that defines a proximal rim of the reflector element. Each reflector element includes an annular sidewall having an inner surface that extends from the proximal annular rim to a distal annular rim. The proximal annular rim defines a first opening through which direct and reflected light from a light source is emitted. The distal annular rim defines a second opening through which the light source is disposed. The inner surface of the annular sidewall is formed from the material of the planar sheet by mechanically deforming the planar sheet, such as by stamping or drawing.

  • Publication number: 20110240304
    Abstract: A method for making a riser component includes: positioning a coupler adjacent and end of a tube such that a region of the coupler forms an interface with the tube's end, wherein the region includes a material (in some embodiments an aluminum alloy), and the tube's end includes a groove and another material (in some embodiments a steel alloy) that is different than the region's material; heating the region of the coupler to increase the region's malleability; and exerting pressure on the region of the coupler to plastically deform the region to insert some of the region's material into the groove in the tube's end. By fixing the coupler to the tube in this manner, the coupler may be strongly secured to the tube, and thus able to withstand high, dynamic loads frequently experienced in service. Also, the material of the coupler may be different than the material of the tube, and thus the material of the coupler may be lighter than the material of the tube.

  • Publication number: 20110239721
    Abstract: Metal sheets and thin-wall metal tubes may be heated to a hot working temperature and transformed by a hot-blow-forming step to achieve shapes, difficult to attain, without excessive thinning or strain causing damage to the workpiece based on the inherent formability of the metal alloy. The stages of forming of the intended shape in the metal workpiece are analyzed and workpiece regions of potential damage during forming are identified. Then, during actual forming, these regions of the hot workpiece are selectively cooled with air (or other cooling fluid) to reduce thinning or strain in the critical region(s) and to redistribute this strain to adjacent lower strain areas of the workpiece. This hot-blow-forming practice is particularly useful in attaining complex shapes in workpieces of aluminum-based alloys and magnesium-based alloys.

    Abstract: Pipe to be upset is conveyed via walking beam though a series of induction heating coils and one end is heated to a maximum temperature of 2350 degrees F. Thereafter, a robot transports the pipe into a forging machine where the pipe end is upset in one or more die pockets. For those types of pipes where the pipe end temperature falls below an acceptable temperature during upsetting, the robot delivers the pipe end to an auxiliary induction heating coil and is re-heated to an acceptable forging temperature. The robot then transports the pipe back into the forging machine where the pipe end is forged to its final upset dimensions.
