The invention relates to a device and a method for forming, in which at least one spindle is driven in a rotating manner by means of a rotary drive, a workpiece is received on the spindle by means of a clamping means and clamped on the spindle and at least one forming roller is fed axially and/or radially relative to the workpiece in order to carry out a spinning or flow-forming process. In accordance with the invention provision is made for the spindle and the clamping means to be combined to a changing unit which is adjustable transversely to the axis of rotation, wherein the changing unit is adjusted between a forming position and a set-up position.

A spinning forming device includes: a rotating shaft that rotates a plate to be formed; a processing tool that presses a transform target portion of the plate to transform the plate; and a heater that locally heats the transform target portion by induction heating. The heater includes an electric conducting pipe, and the electric conducting pipe includes a coil portion extending in a circumferential direction of the rotating shaft and having a doubled circular-arc shape facing the plate. A cooling liquid circulates through the electric conducting pipe by a circulating device.

The present invention relates to a method of manufacturing a pressure vessel.

Method of manufacturing of components used in the field of aviation aircraft and, specifically, an aircraft engine nacelle lipskin. Instead of spinning flat plates, this method uses spinning a cylinder, thus eliminating waste material. It also eliminates the need for rivet lines which results in better laminar flow. Further, there is a reduction of other costs in addition to reducing drag.

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.
