摘要： The invention relates to a method and a forming machine for deforming a workpiece, such as a metal cylinder or plate (3), by means of a tool, in particular one or more forming rollers (5), wherein the workpiece and/or the tool are rotated about an axis (4) relative to each other, the tool move; through one or more deforming curves and at least part of the workpiece is deformed. During the deforming process, values of one or more coordinates of the position of the extreme: edge of the workpiece are measured, and one or more parameters of the deforming process is/are changed on the basis of the measured values.

摘要： Method and apparatus for spinning a product, wherein a metal plate (3) which may be preshaped or not, is deformed on a rotating chuck (2) by a forming roller (4) into a hollow product with a wall thickness. The shape of the chuck is determined and is stored in a memory of a control unit (6) as a series of successive points. The control unit moves the forming roller according to a path corresponding with the shape of the chuck. This path is determined by the stored shape of the chuck with a desired wall thickness (S1) of the product added thereto. The metal plate is deformed by moving the forming roller according to the thus determined path. In each point of the stored shape of the chuck, the control unit determines a tangent line (20) of the chuck shape at the location of this point and adds the desired wall thickness to the wall thickness at the location of this point according to a line perpendicular to the tangent line to calculate the path of the forming roller.

摘要： The invention relates to a forming machine (1) comprising a rotatably drivable gripping device (2) for gripping a workpiece, such as a plate of stock material, for example, which gripping device comprises a first forming tool (3) and a press-on tool (4) for pressing the workpiece in the direction of said first forming tool. The forming machine furthermore comprises a second forming tool (18), which is mounted at least substantially coaxially round the press-on tool, which second forming tool can be moved along the press-on tool. With the forming machine according to the invention the workpiece can be worked in two opposite directions without there being a need to remove the workpiece.
