The invention relates to an adjustable sizing device for sizing extruded endless profiled pieces, particularly tubes, comprising a sizing opening that is formed by a multitude of peripherally arranged, radially adjustable segments (24) each having a segment body whose inner surface jointly forms the sizing opening. Each segment body has at least one actuating device (12), with which the individual segments (24) are held inside a housing, and an adjustment of one of each segment bodies can be effected in a radial direction. In order to ensure a simple and cost-effective installation of the sizing cage, the invention provides that at least one installation ring (11) is provided that, arranged in a peripheral direction, has a number of radially extending boreholes that corresponds to the number of segment bodies. The actuating devices (12) are precisely accommodated and oriented inside of said boreholes. |
