Description

Einstellvorrichtung für Pilgerschrittwalzwerke Die Erfindung betrifft eine Einstellvorrichtung für die Arbeitswalzen von Pilgerschrittwalzwerken.Adjustment device for pilgrim step rolling mills The invention relates to an adjustment device for the work rolls of pilger step mills.

Es ist bereits eine Winkeleinstellung für die Walzsektoren bei Pilgerschrittwalzwerken bekannt, durch die eine geringfügige Verstellung von einer oder von beiden Arbeitswalzen möglich ist. Diese Verstellung erfolgt in AcJhsrichtung, womit eine nachteilige seitliche Verschiebung der- Walzen gegeneinander in Achsrichtung zwangläufig eintritt. Außerdem können durch diese bekannte Winkeleinstellung nur geringe, durch den Verschleiß bedingte Differenzen ausgeglichen werden.It is already an angle setting for the rolling sectors in pilger step rolling mills known by a slight adjustment of one or both work rolls is possible. This adjustment takes place in the axis direction, which is a disadvantage lateral displacement of the rollers against each other in the axial direction inevitably occurs. In addition, due to this known angle setting, only small amounts can be achieved due to wear conditional differences are compensated.

Bei der erfindungsgemäßen Winkeleinstellung für die Arbeitswalzen von Pilgerschrittwalzwerken, bei denen die hin und her schwingenden Walz-Sektoren auf dem während des Arbeitshubes feststehenden Walzgut abgewälzt werden, geschieht dies im Gegensatz zur vorbekannten Winkeleinstellung dadurch, daß beide Walzsektoren mit . den kämmenden Stirnrädern starr gekuppelt oder verkeilt sind, und dadurch, daß durch die Verdrehung eines Kammrades mittels einer verschiebbaren Zahnstange die Verdrehung beider Walzsektoren gleichzeitig erfolgt.With the angular adjustment according to the invention for the work rolls of pilgrim step rolling mills, in which the rolling sectors oscillate back and forth are rolled on the rolling stock that is stationary during the working stroke, happens this in contrast to the previously known angle setting in that both rolling sectors with . the meshing spur gears are rigidly coupled or keyed, and thereby, that by rotating a comb wheel by means of a sliding rack the rotation of both rolling sectors takes place at the same time.

Auf diese erfindungsgemäße Weise wird eine axiale Verstellung der Walzsektoren in axialer Richtung ausgeschlossen, und trotzdem können die Sektoren eine ganz erhebliche Winkelverstellung erfahren, so daß die Kaliberöffnung praktisch stufenweise in allen Zwischenstufen eingestellt und in der Endstufe Millimeter betragen - kann. Die erfindungsgemäße Winkelverstellung hat auch.noch den Vorteil, daß die Werkzeughaltung billiger wird.In this way according to the invention an axial adjustment of the Rolling sectors excluded in the axial direction, and still the sectors experience a very considerable angle adjustment, so that the caliber opening is practical gradually adjusted in all intermediate levels and in the final stage Be millimeters - can. The angular adjustment according to the invention also has the advantage that the tool maintenance is cheaper.

PATENTANSPRUCH: Einstellvorrichtung für die Arbeitswalzen von Pilgerschrittwalzwerken, bei denen die hin und her schwingenden Walzsektoren auf dem während des Arbeitshubes feststehenden Walzgut abgewälzt werden, dadurch gekennzeichnet, daß die beiden Walzsektoren mit den kämmenden Stirnrädern starr gekuppelt oder verkeilt sind und durch die Verdrehung eines Kammrades mittels einer verschiebbaren Zahnstange die Verdrehung beider Walzsektoren gleichzeitig bewirkt wird. Angezogene Druckschriften: Deutsche Patentschriften Nr. 58 762, 29o 02o. PATENT CLAIM: Adjustment device for the work rolls of pilgrim step rolling mills, in which the reciprocating rolling sectors are rolled on the rolling stock stationary during the working stroke, characterized in that the two rolling sectors are rigidly coupled or wedged with the meshing spur gears and by rotating a comb wheel a sliding rack, the rotation of both rolling sectors is effected at the same time.
