072068000 | With metal deformation of different type | 10 |
20090249853 | Method and Device for Bending Electric Machine Conductors - A twisting device comprises at least one conductor coupler configured to engage a plurality of the conductors and at least one drive operably connected to the conductor coupler. The at least one drive is configured to rotate the conductor coupler in order to bend the plurality of the conductors and simultaneously move the conductor coupler in an axial direction relative to the electric machine component. An associated method of bending conductors positioned in a component of an electric machine comprises first engaging a plurality conductors with a conductor coupler. Thereafter, the plurality of conductors are bent by rotating the conductor coupler while simultaneously moving the conductor coupler in an axial direction relative to the component of the electric machine. | 10-08-2009 |

20100107713 | METHOD AND DEVICE FOR ROLLING A ROLLING STOCK IN A ROLLING MILL WITH A CROSS-ROLLING MILL - The invention relates to a rolling mill for rolling stock to be rolled ( | 05-06-2010 |
20120167651 | METHOD AND APPARATUS FOR MANUFACTURING A BENT MEMBER - A bending apparatus has (a) a first manipulator which feeds a hollow metal blank of closed cross section in its lengthwise direction, (b) a second manipulator which supports a first support means disposed at a first position and a metal blank while feeding it, a heating means disposed at a second position downstream of the first position in the blank feed direction for heating all or part of the circumference of the blank, and a cooling means disposed at a third position downstream of the second position for cooling a portion of the heated blank, and (c) a third manipulator which constitutes a second support means disposed at a fourth position downstream of the third position in the feed direction of the blank and which moves two-dimensionally or three-dimensionally while supporting at least one location of the metal blank to bend the metal blank into a desired shape. | 07-05-2012 |
20120304723 | METHOD OF MANUFACTURING A WHEEL RIM FOR A VEHICLE - A method of manufacturing a wheel rim for a vehicle includes an ironing step for ironing a tubular material to manufacture a tubular member having a non-constant thickness, using an ironing apparatus provided with a punch, a die whose side surface opposing the punch is a convex and concave surface, and a pressing member. At the ironing step, a flange portion of the tubular material is set at the die, then the pressing member is moved relative to the die thereby to squeeze the flange portion of the tubular material by the pressing member and the die, and then the punch is moved relative to the die to iron at least a portion of the tubular material except the flange portion of the tubular material to manufacture the tubular member having a non-constant thickness. | 12-06-2012 |
20150013416 | MANUFACTURING METHOD AND MANUFACTURING APPARATUS OF SCREW-THREADED BOTTLE-CAN - A manufacturing method for a screw-threaded bottle-can including the steps of: forming a shoulder part, a pipe part, a tapered part and an aperture-end part above a trunk part; and forming a screw-thread part by an inner mold and an outer mold in which the pipe part is sandwiched therebetween. An outer diameter of the pipe part is formed to an intermediate diameter between a ridge diameter and a bottom diameter of the screw-thread part. The screw-thread part is formed from the tapered part to the pipe part so as to form a screw-starting part at an intermediate position of the tapered part. A height of a first step of a right-hand screw-type protrusion of the inner mold is formed to be lower than a height of a second and subsequent steps in an angle range of 90° circumferentially continuing from the screw-starting part. | 01-15-2015 |
20150059426 | APPARATUS AND METHOD FOR MANUFACTURING A SEAMLESS PIPE - Provided is an apparatus of manufacturing a seamless pipe. The apparatus includes a container receiving a work therein, a stem pressing one end of the work within the container, a die installed in a direction opposite to the stem, and having an extrusion hole comprised of a plurality of ports, a rotation member installed on a front end of the die, having a stirring tip inserted into a joint surface formed by abutting a plurality of metal pieces to each other on one surface, and rotating to perform a friction stir bonding in a state in which the one surface contacts the joint surface, and a correction mold including a metal pipe discharging path receiving a metal pipe manufactured by the friction stir bonding and discharging the metal pipe to an outside. | 03-05-2015 |
20150075242 | FRICTION-STIR EXTRUDERS AND FRICTION-STIR EXTRUSION PROCESSES - A friction-stir mandrel includes a textured end portion integral with a body portion. The textured end portion is configured to friction-stir process a starting material forced across the textured end portion and through a die in a plasticized state to form a pipe. A pipe can be formed by forcing a starting material across a textured end of the mandrel and through a die in a plasticized state, so that the textured end of the mandrel breaks up existing grains of the starting material. The pipe is formed from material that is forced through the die. The friction-stir mandrel can be used with porthole die friction-stir extrusion, seamless tube friction-stir extrusion, and tube friction-stir drawing processes to provide tubing in which the grains are broken up by the textured portion of the friction-stir mandrel. The textured portion can include features, such as threads, ridges, studs, protrusions, and the like. | 03-19-2015 |
20150089986 | METHOD AND DEVICE FOR RESHAPING A WORKPIECE - The invention relates to a method for reshaping a workpiece comprising a central axis, a radial inner region, and a radial outer region, in which the radial inner region of said workpiece is reshaped by means of a punch and a die by a drawing operation in the axial direction with formation of an axial shaped section. Provision is made for the workpiece, the die, and the punch to be rotated about the central axis during the reshaping process by a drawing operation and for the radial outer region of said workpiece to be subjected, during reshaping by a drawing operation of the rotating workpiece, to the action of at least one shaping roller such that a flow of material in the direction of the radial inner region of said workpiece is caused or aided. The invention further relates to a device for reshaping a workpiece. | 04-02-2015 |
20160089708 | Method and device for producing rotationally symmetrical metal components - 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. | 03-31-2016 |
