METHOD AND DEVICE FOR FORMING A WORKPIECE

摘要

A device (1) for forming a hollow and at least essentially rotation-symmetric workpiece (4), having an inner forming tool (3) for supporting an inner contour of the workpiece (4) and an outer forming tool (2) for introducing a forming force into an outer contour (10) of the workpiece (4). The workpiece (4) can be rotated relative to the outer forming tool (2) around an axis of rotation (X). The device (1) has a machining tool (15) and is designed such that the machining tool (15) can act upon the outer contour (10) of the workpiece (4) at the same time as the forming tool (2) in order to insure that the diameter of the workpiece (4) is uniform before the workpiece (4) is acted upon by the forming tool (2) to prevent whip arm or curvature in the workpiece (4).

1. A device (1) for forming a hollow and at least essentially rotation-symmetric workpiece (4), the device (1) having an inner forming tool (3) for supporting an inner contour of the workpiece (4) and an outer forming tool (2) for introducing a forming force into an outer contour (10) of the workpiece (4), wherein the workpiece (4) can be rotated relative to the outer forming tool (2) around an axis of rotation (X), characterized in that the device (1) has a machining tool (15) located proximate the workpiece (4) and proximate the outer forming tool (2) and wherein the machining tool (15) is configured such that the machining tool (15) acts upon a predetermined portion of the outer contour (10) of the workpiece (4) prior to said predetermined portion of the outer contour (10) being acted upon by said forming tool (2) and at the same time as the forming tool (2) is acting upon a prior predetermined portion of the outer contour (10) previously acted upon by said machining tool (15).
