Abstract: An apparatus for drawing-in a pipe end by plastic cold forming includes a clamping body. An annular body disposed on the clamping body has an inner surface and a center. An internal tool in the form of a stop ring is centrally supported on the clamping body for defining a desired inside pipe profile. A plurality of jaws is disposed on the clamping body for extending over the outside of a region of a pipe to be drawn-in. The annular body has blind bores serving as cylinders formed therein in radial directions with openings facing toward the inner surface of the annular body. Pistons connected to the jaws are inserted in the cylinders and movable radially toward the center of the annular body by a pressure medium. The stop ring has individual stops in the form of stop heads with threaded shafts being radially adjustably screwed into radial threaded bores formed in the stop ring. The threaded shafts may be rotated.
