Metal member manufacturing method

A metal member manufacturing method according to one form of this disclosure is a method of manufacturing a metal member that is thinner at some portions than at other portions. The method includes a formation step of pressing one surface of surfaces of a metal workpiece that are perpendicular to a thickness direction with a press-working die so as to form a raised portion in the other surface, and a cutting step of moving a cutting blade along the other surface to cut off the raised portion by shaving. In the formation step, the raised portion is formed such that the area of a cross-section of the raised portion that is parallel to a moving direction of the cutting blade and perpendicular to the other surface decreases toward an end of the raised portion on a rear side in the moving direction of the cutting blade.

METHOD FOR PRODUCING A SOLDER DEPOSIT, AND SOLDER DEPOSIT
20220402059 · 2022-12-22 · ·

in a method for producing a solder deposit in a metal sheet, a depression is made in a topside of the metal sheet through deep drawing, thereby causing material to protrude on a bottom side of the metal sheet. The metal sheet is then subjected to a material forming process to produce a collar such that the collar projects in relation to the topside. The collar is then at least partially pressed in a direction of the depression to reduce a cross-sectional area of a mouth of the depression, and the protruding material on the bottom side is completely pushed back so that the bottom side in a region of the depression is in one plane with neighboring regions of the bottom side.

Heavy-duty connections e.g. for axle/suspension systems

A vehicle component such as an axle spindle or suspension beam (3) is connected to a tubular vehicle axle (1) by fitting a connector sleeve (2) onto the axle and subjecting the assembly to a crimping operation in which plural depressions (206,2018) are formed by indentation in the connector sleeve and the axle wall at the connection region (11,12) to fix the connector sleeve on the tubular axle. In the described proposals a solid lubricant (4) such as molybdenum disulphide is applied at the connection region between the connector sleeve (2) and axle (1), before crimping. The further vehicle component (3) is then connected to the connector sleeve (2) by welding.

HEATSINK WITH PROTRUDING PINS AND METHOD OF MANUFACTURE

A heatsink, a light-emitting diode (LED) module and a corresponding method of manufacture are described. A heatsink includes an electrically conductive heatsink core and an electrically insulating layer covering at least the first surface of the electrically conductive heatsink core. The electrically conductive heatsink core has a first pin that is integral with the electrically conductive heatsink core and protrudes from a first surface of the heatsink core. At least the first surface of the heatsink core is covered by an electrically insulating layer, which leaves at least portions of a lateral surface of the first pin exposed from the electrically insulating layer.

Heat exchanger tube with flattened draining dimple

A heat exchanger includes a tube having a length and an outside boundary. The tube is configured to convey fluid therethrough to facilitate heat transfer, and the outside boundary of the tube having a bottom wall portion, a top wall portion opposing the bottom wall portion, and two side wall portions between the bottom wall portion and the top wall portion, in which a segment of the length of the tube has a plurality of dimples selectively placed outside of the bottom wall portion.
