The invention relates to a calibration device for calibrating extruded continuous profile, in particular tubes. The inventive device comprises a plurality of successively arranged segmented crowns consisting of individual segments (18, 18', 18'') whose internal surfaces jointly form a calibration opening. Said successively axially arranged segments (18, 18', 18'') are assembled in the form of a segmented block (16). The individual segments (18 , 18', 18'') of each segmented block (16) are arranged on a support structure (30, 30'), and the segmented blocks (16) are arranged, in an essentially circular form, in a body (12, 14) in such a way that the axially adjacent segments (18, 18', 18'') are partially superposed upon each other at each position thereof in a circumferential direction. Each support structure (30, 30') is connected to at least one fixing and actuating (20,20') device. The individual segmented blocks (16) which are associated to the support structures (30, 30') thereof are fixed to the body (12, 14) with the aid of said fixing and actuating (20, 20') device, the adjustment of each segmented block (16) being carried out in an axial direction. In order to facilitate t he integration and assembly, each fixing and actuating device (20, 20') is divided into two parts, i.e. the firstpart (42, 60) connected to the support structure (30, 30') and the second part (40, 62) arranged in the body (12, 14), said two parts are mutually assembled in a separable manner. |
