The present disclosure relates to a method for producing a shaped sheet metal component from a billet by means of U O forming, wherein firstly a preform is created by the U-forming and then a final shaping is performed by the O forming to give a final form.

A vehicle door beam and related methods of making door beams include a flat-rolled aluminum alloy sheet, where two edges of the sheet that are transverse to the roll direction of the sheet are brought together to form a tube. The two edges are friction stir welded together to form a butt joint along a length of the tube. The tube is arranged, along with other optional components, as a side-impact door beam in a vehicle door, such that the butt joint is facing away from an expected impact direction of the vehicle door.

A method of producing a drum including providing at least one source of at least one material, producing a preform from the at least one material, bending edges of the preform into a rolled preform and joining the edges to form a tubular member, performing an expansion operation and/or a contraction operation on the tubular member to achieve at least one desired diameter of the drum, heat-treating of the tubular member, forming a plurality of engagement elements in the tubular member, machining the tubular member, heat-treating the drum to achieve a desired hardness, assembling at least one secondary component with the tubular member, and balancing the drum.

A die set capable of suppressing breakage or wrinkling of the workpiece during bending and a processing method using the die set. A die set used for bending a plate-like workpiece includes a lower die on which the workpiece is placed, and an upper die having a pressing surface formed to press the workpiece against the lower die. The lower die includes a lower movable part slidable in the same direction as a moving direction of the upper die, a reaction force generating member configured to elastically support the lower movable part from beneath, and receiving members located on both sides of the lower movable part. The pressing surface has an arc-shaped cross-section protruding toward the lower die and extends in a longitudinal direction of the workpiece. The maximum push-in position of the lower end portion of the pressing surface is deeper than a position lowered by a finished inner diameter dimension of the workpiece from an upper surface of the lower die.

A method is executed to make a reel assembly of a tie-down. The method includes the steps of providing a ratchet with teeth and slots, providing a spool with protuberances, connecting the ratchet to the spool by inserting the protuberances of the ratchets in the slots of the spool, and enhancing the connection of the ratchet to the spool.

A shielding electrical terminal is presented herein. The shielding electrical terminal includes a securing portion that is configured to attach to an outer shield conductor of a shielded cable and a cylindrical mating portion having an inner surface configured to make electrical contact with a corresponding cylindrical shield terminal inserted within the mating portion. The inner surface of the mating portion defines a plurality of protrusions that extend from the inner surface.

Provided is a method of manufacturing a pipe including a large-diameter portion, a small-diameter portion, and a reduced diameter portion connecting the large-diameter portion and the small-diameter portion, the method comprising: forming a metal plate member into a U-shaped member having a U-shaped cross section; and forming the U-shaped member into a shape of the pipe. The U-shaped member includes: a curved portion facing an opening between both edges of the U-shaped cross section; and two facing side walls continued from the curved portion. An opening degree of the two facing side walls in a portion to form the small-diameter portion is larger than an opening degree of the two facing side walls in a portion to form the large-diameter portion.
