Abstract
Gezeigt ist eine Anordnung und Ausbildung für die Rollen (1, 4; 2, 5; 3, 6) einer Schrägrollenrichtmaschine. Diese sind in Durchlaufrichtung (Pfeil 8) des Richtgutes (7) paarweise einander gegenüberliegend und hintereinander angeordnet. An arrangement and training for the is shown Rollers (1, 4; 2, 5; 3, 6) of an inclined roller straightener. These are in the direction of flow (arrow 8) of the target (7) in pairs opposite each other and one behind the other arranged.
Empfindliche runde, metallische Rohre mit dünner Wand werden, wegen der sonst bestehenden Gefahr blei bender unerwünschter Deformationen und erhöhter Eigen spannungen im Rohr, nur durch Biegen gerichtet. Die Flä chenpressungswerte auf das Richtgut werden durch Anpas sung der Rollenanordnung und -Ausbildung an die Biegeli nie des Richtgutes herabgesetzt. Der von den Auflagerrol len (1, 3) und den zugehörigen Führungsrollen (4, 6) gebil dete Führungskanal für das Richtgut (7) wird um einen Winkel (alpha) gegen den geraden Durchlauf (40) ge schwenkt und die wirksamen Längen (19, 20, 21) der Rollen (5, 1, 3) werden den Richtkräften angepaßt. Die Biegerolle (5) ist länger ausgebildet als die Auflagerollen (1 und 3). An einzelnen Richtrollen (3) sind Leitschrägen (22) vorgese hen, um das Richtgut (7) auf die stärker gekrümmte Bahn zu bringen. Einige Auflagerrollen sind axial verschieblich. Delicate round, metallic tubes with thin Wall, because of the otherwise existing danger lead unwanted deformations and increased self Tensions in the pipe, only straightened by bending. The Flä Pressure values on the target material are adjusted Solution of the roll arrangement and training to the Biegeli never discounted the token. The one of the support roller len (1, 3) and the associated guide rollers (4, 6) The guide channel for the leveling material (7) is increased by one Angle (alpha) against the straight pass (40) ge pivots and the effective lengths (19, 20, 21) of the rollers (5, 1, 3) are adjusted to the straightening forces. The bending roll (5) is longer than the support rollers (1 and 3). At individual straightening rollers (3) are provided with guide bevels (22) hen to align the target (7) on the more curved path bring to. Some support rollers can be moved axially.
