Abstract

See full text

The method resides in profiling a part of a cylindrical pipe by drawing it through a moulding device, and reducing the pipe over its entire length for the diameter of the cylindrical part of the pipe to be substantially equal to the diameter of the circumscribed circle of its profiled part. The apparatus for performing the method comprises a drawing bench supporting a drawing die (2) accommodated in a housing (1) and a drawing carriage. Cams (6) are situated in front of the drawing die (2) at both sides of the path of the travel of a pipe (5) being manufactured, their one ends carrying deforming rollers (7) and their other ends carrying forked levers (8) cooperating with the drawing carriage through a tie (11) with slots (10) receiving therein lock pins (9) adapted to engage the forked levers (8). The apparatus further includes a pivoted lever (29) with a bearing roller (31), mounted on the housing (1). One arm of the pivoted lever (29) is adapted to engage the pipe (5) being profiled through the bearing roller (31), and the other arm thereof carries pivotally mounted stops (26) adapted for periodical cooperation with the cams (6).
