Method and apparatus for producing metal profiles with small dimensions chamber tolerance

摘要

The present invention is directed to a method and apparatus for producing metal profiles having a flange inner surface are spaced apart from each other only the last chamber size fraction tolerances and small, have profiles of the two flanges which are disposed to face each other . In order to vary the chamber dimension in the final chamber dimension K ₁ of the desired starting chamber dimensions K _0, it is passed through the apparatus for forming a machining gap between the outer support rolls inside and work roll the metal profile. To support each other molding force applied to the processing roll pair from the flange inner surface processing roles that form the inner processing roll pair, rolling each other mutually.
