摘要： A method for producing a sintered part, having at least the following steps: a) providing a sintered part, said sintered part having a first end face, a second end face arranged at a distance from the first end face in an axial direction, and a circumferential surface between the end faces; b) arranging the sintered part in a tool; c) applying a first pressure force, which acts on the end faces at least in the axial direction, to the sintered part by the tool; and d) applying a second pressure force, which acts on the circumferential surface at least in a radial direction, to the sintered part, wherein the sintered part is reshaped at least by the second pressure force, or mechanically processing the sintered part. Steps c) and d) are carried out at least partly simultaneously.

摘要： A forging apparatus includes an ironing mechanism and a phase alignment mechanism. The ironing mechanism includes: a punch set, which is fitted into a cylindrical portion of a pre-processing material to be formed into the outer joint member, and is radially expandable and contractible, the cylindrical portion having grooves formed in an inner peripheral surface thereof; and a die having a hole into which the cylindrical portion is press-fitted. The phase alignment mechanism is configured to align phases of the grooves in the inner peripheral surface of the pre-processing material and phases of track groove portion forming surfaces of the punch set with each other before the pre-processing material is fitted to the punch set.

摘要： In a pressing step, a first forged product is pressed by a first die, and thereby, a second forged product including a rough flange having a thickness-changing portion is produced. The thickness-changing portion includes a front part protruding frontward from a side of a rough web part and a rear part protruding rearward from the side of the rough web part. Each of the front part and the rear part includes a first part, and a second part that is thicker than the first part and is located farther from the rough web part than the first part. In the pressing step, at least a part of the rough flange that is above or below the web part (thick part) is pressed by the first die, whereby the material of the first forged product in the part is caused to flow frontward and rearward, and the thickness-changing portion is formed.

摘要： A gas sensor (1) has a sensor element (21) extending in an axis direction and having, at a top end side thereof, a detecting portion (22) that detects gas; a stainless steel-made tubular metal shell (11) enclosing a radial direction periphery of the sensor element (21) and holding the sensor element (21) and having (a) a brim portion (14) protruding outwards in a radial direction and (b) a crimp portion (16) formed at a rear end side of the metal shell (11); and a sealing member (41) placed between the sensor element (21) and the metal shell (11). The crimp portion (16) is bent inwards in the radial direction and pressing down a rear end of the sealing member (41) toward the top end side. A Micro Vickers hardness of a cross section along the axis direction of the crimp portion (16) is 140 to 210 Hv.

摘要： The invention relates to the production of profiled hose nipples. The invention was based on the object of providing a method and an apparatus which allow hose nipples of the type outlined in the introduction to be produced in a simple manner such that the formation of burrs is avoided and there is no reduction in diameter. This object is achieved in that during the forming of pipe portions (1) in the apparatus (2, 7, 9) according to the invention in the region of the subsequent ring-shaped webs (4) of the nipple profile (3), the material of the pipe portion (1), at its outwardly pointing end (4), does not come into contact with the tool in the region of the parting joints (6) of the apparatus (2, 7). This can be realized by additional cavities (14) in the tool (2, 7).

摘要： A device for lightening the weight of vehicle components includes a tooling provided with a seat wherein the component is formed and a plurality of moveable bodies, which are moveable between an initial position and a final position, such that in the final position one end of each moveable body penetrates the seat of the tooling to form a cavity to lighten the weight of a component of the vehicle, wherein at least one of the moveable bodies can move laterally. Such device allows lightening the weight in a more simple and productive way than in currently known systems. This is achieved because the moveable bodies do not interfere with each other during the movement thereof, such that the lightening process can be done in a single blow during a forging procedure.

摘要： A method for forming a QCr0.8 alloy tapered cylindrical ring, including: heating a standard QCr0.8 alloy cylindrical part followed by upsetting and stretching at least twice to obtain a primary blank; heating the primary blank followed by upsetting and chamfering to obtain a secondary blank, where a diameter of a top end is greater than that of a bottom end; subjecting the secondary blank to backward extrusion to form a preform; machining the preform to remove a flash and a bottom residue; subjecting a bottom end of the preform to local bulging to enable a shape and a size thereof to match that of a drive roller in a forming tooling, so as to form a profiled ring blank; and rolling the profiled ring blank by a radial-axial ring rolling machine with the forming tooling to form the tapered cylindrical ring.
