| 20090049881 | Method of forming a tubular ring - A method of forming a tubular ring comprising spinning a flat blank having a bore, expanding the bore using a tubular shaft shaped spinning roller by initially engaging the tubular shaft shaped spinning roller with the flat blank bore at an angle (α) to the spinning axis, forming the flat blank into a tubular ring by rotating the tubular shaft shaped spinning roller about a center of rotation (B) such that the tubular shaft shaped spinning roller becomes substantially parallel to the spinning axis, and forming a contour on an outer surface of the tubular ring. | 02-26-2009 |
| 20090301153 | METHOD AND APPARATUS FOR PROCESSING A PREFORM FOR A RIM, AND RIM - A method for processing a preform for a rim wherein a ring-shaped rudimentary metal rim edge ( | 12-10-2009 |
| 20100011828 | Deformation of Thin Walled Bodies - A thin walled body is deformed in a process in which the body is gripped securely in a holding station and, whilst gripped in the holding station, tooling engages to deform the peripheral wall of the body at a predetermined wall zone. The tooling is provided at a tooling station which is adjacent the holding station during deformation. The predetermined wall zone is co-aligned with the tooling by rotation of the body about an axis prior to securing at the holding station. | 01-21-2010 |
| 20130133390 | METHOD AND APPARATUS FOR MAKING A COLLAR TO THE END OF A PIPE - A method and apparatus for making a collar to the end of a pipe. The apparatus comprises an attachment clamp surrounding the pipe and a body part, connected by hinging to a pivoting cradle having a forming cone, which can enter the end of the pipe. In the method, the forming cone is moved axially and obliquely to the central axis of the pipe, inside the pipe until it contacts the inner surface of the pipe, the forming cone being loaded with the desired load pressure against the inner surface. The forming cone is then pivoted using a pivoting cradle outwards from the central axis of the pipe, around the inner edge of the attachment clamp, and the forming cone and pipe are simultaneously rotated with respect to each other around the central axis of the pipe until the desired collar has formed. | 05-30-2013 |
| 20150328673 | SPINNING FORMING DEVICE - An object of the present invention is to reduce heat transferred from a plate through a receiving jig to a rotating shaft in a spinning forming device. A spinning forming device includes: a receiving jig supporting a central portion of a plate to be formed; a rotating shaft to which the receiving jig is attached; a heater configured to heat a transform target portion of the plate by induction heating; and a processing tool configured to press the transform target portion to transform the plate. The receiving jig is configured to suppress heat transfer from the plate to rotating shaft. | 11-19-2015 |
| 20160052036 | SPINNING METHOD AND SPINNING APPARATUS - A spinning method includes supporting a supported portion of a cylindrical work by a work supporting portion; pressing a first roller of a spinning head against a processed portion of the work while revolving the first roller; and performing a forming process that points a tube axis of the processed portion of the work in a given direction by pressing the first roller and a second roller in which a plane of revolution thereof is provided in a different position, in a rotational axis direction of a spindle of the spinning head, than a plane of revolution of the first roller, while revolving the first roller and the second roller, and moving the work supporting portion relative to the spinning head or moving the spinning head relative to the work supporting portion, while the first roller and the second roller work in cooperation with each other to retain the work. | 02-25-2016 |
| 072083000 | With means causing cooperating presser member to traverse form surface | 5 |
| 20080236232 | Method of spinning multiple parts - A method of spinning multiple parts comprising attaching two blanks to an intermediate mandrel, loading the intermediate mandrel and blanks into the spinning machine by clamping the intermediate mandrel and the blanks between the spinning machine tailstock and the headstock, moving rollers simultaneously radially inward and outward to execute metal forming on each blank to form a part from each blank, ejecting the intermediate mandrel, and ejecting each part substantially simultaneously from the intermediate mandrel. | 10-02-2008 |
| 20090205386 | Method for forming an end portion of a cylindrical workpiece - A method for forming a part of deformed cross section with non-rotation symmetry on an end portion of a cylindrical workpiece. The method includes steps of performing a first relative motion of a roller against the workpiece toward its one open end, and performing a second relative motion of the roller against at least a part of outer peripheral surface of the end portion of the workpiece toward the inside thereof, while the roller is rotated relative to the workpiece by one rotation, in such a state as being held to be in contact with the end portion, in a plane which is perpendicular to the moving direction of the first relative motion, and which includes a position where the roller contacts the outer peripheral surface of the end portion, and performing a rotational motion of the roller relatively rotating around the workpiece, while performing the second relative motion, with the roller being held to be in contact with the outer peripheral surface of the end portion. The first relative motion is performed up to a position exceeding the one open end, while repeating the second relative motion and the rotational motion. | 08-20-2009 |
| 20090211323 | Method of Forming a Circular Sheet-Metal Blank - A method of forming a circular sheet-metal blank which rests on a tool rotating about an axis. The sheet-metal blank has a thickness and has a diameter which is small than a diameter of the tool. | 08-27-2009 |
| 20120011911 | FLOW FORMED GEAR - A method of forming a ring gear from a ring blank includes providing a mandrel having a central axis and an outer annular forming surface. The outer annular forming surface defines a plurality of forming elements having a forming element axis offset from the central axis of the mandrel. The ring blank has a ring axis and is placed over the mandrel generally aligning the central axis of the mandrel with the ring axis of the ring blank. A roll is provided having a roll axis that is generally parallel with the element axis. The roll is forced radially inwardly while circumscribing the central axis. The roll pivots around the roll axis deforming the ring blank radially inwardly forming teeth on an inner surface of the ring blank that coaxial with the element axis and offset from the mandrel axis. | 01-19-2012 |
| 20150343511 | APPARATUS FOR MANUFACTURING LONG-NECK FLANGE BY APPLYING ROLLER SPINNING AND METHOD THEREFOR - Disclosed is an apparatus for manufacturing a long-neck flange comprising: a pipe support bar for supporting the inside of a pipe, the pipe support bar being rotatable; a rotatable pressurizing device connected to the pipe support bar for simultaneously rotating, pressurizing, and conveying the pipe with one end fixed thereto; a face roller for contacting a cross section of the pipe support bar to form a flange surface; a curvature roller positioned at the outside of the pipe for giving a curvature to the flange part; and a circumferential roller positioned at the outside of the pipe in the circumferential direction so as to form the width of the flange part. | 12-03-2015 |
