A method for producing rotationally symmetric structural components of metal, in particular steel, is provided. A blank is arranged in a torsion-proof manner on a first receptacle, the receptacle is rotated about a rotation axis so that the blank is caused to rotate about this rotation axis, at least one linear shaping element with a contour having at least partially an unrolled external contour of the rotationally symmetric structural component or a preform of the structural component is moved tangentially to the surface of the synchronously rotating blank, and the linear shaping element is at the same time pressed against the blank so that during the tangential movement the contour of the linear shaping element is formed at least partially into the blank. A kingpin or link pin of a connection link with a connection shaft and a link outer part is produced.

The present invention relates to a tubular element for a gas pressure container of an airbag system of a motor vehicle, wherein the tubular element (10) has at least one first length section (100, 101) and at least one recess (11) extending in the circumferential direction, characterized in that the tubular element (10) has at least one second length section (102), formed by the recess (11) extending over at least a part of the circumference of the tubular element (10), that the second length section (102) lies between two first length sections (100, 101), that in at least one first length section (100, 101) the outer radius (A1) of the tubular element (10) is greater than the smallest outer radius (A2) of the at least one second length section (102), that the tubular element (10) has a tensile strength of >920 MPa, that the wall thickness (W2) of the tubular element (10) in the at least one second length section (102) is thicker than or equal to the wall thickness (W1) in at least one first length section (100, 101) of the tubular element (10), that the degree of reduction of the outer radius (A2) in the recess (11) lies in the range of 5 to 35% relative to the outer radius (A1) of at least one first length section (100, 101), and that the tubular element (10) consists of a material which, in addition to iron and impurities due to melting, comprises the following alloying elements in the ranges indicated in percent by weight: C 0.05-0.2% Si0.9% Mn 0.2-2.0% Cr 0.05-2% Mo<0.5% Ni<1.0% Nb 0.005-0.10% Al<0.07% Ti<0.035% and B<0.004%.

A pipe/fitting having an end having a modified crimp for securing both flexible ducts and pipes. Specifically, the pipe/fitting includes an end having a series of annularly disposed pipes. The modified crimp includes an outwardly facing channel in the base of the series of crimps configured to secure a flexible duct between the channel and a fastener received in the channel. The end also includes a pipe coupling system at the base of the series of crimps configured to couple a pipe to the conduit.

A process to plastically deform a metallic tubular member includes heating a portion of the tubular member to at least 350 degrees Celsius, performing a feeding operation on the tubular member by applying axial force to one end of the tubular member to plastically deform a primary deformed portion of the tubular member, and subsequently creating one of a bent portion in the tubular member and a secondary deformed portion in the tubular member between the one end of the tubular member and the primary deformed portion.

A power tool includes an outer housing having a drive unit support portion and a handle portion, an inner housing positioned at least partially within the outer housing, and a drive unit positioned in the drive unit support portion, the drive unit including an output member. The power tool also includes a power screw mechanism with a nut fixed relative to the outer housing and a screw coupled for co-rotation with the output member and axially movable relative to the output member. The screw is in threaded engagement with the nut such that the screw moves axially in response to rotation of the screw relative to the nut. The power tool also includes a working assembly coupled to the inner housing for movement in response to axial movement of the screw.
