Abstract

Die Erfindung betrifft ein Kaltpilgerwerkzeug zur Herstellung von innenverrippten Rohren nach dem Kaltpilgerschrittverfahren in einem in Walzrichtung hin- und herbewegbaren Walzgerüst mit verjüngend kalibrierten Walzen, die mit wechselndem Drehsinn über dem Walzgut abrollen, in dem sich ein ebenfalls verjüngender Kaltpilgerdorn befindet. Dabei weist der Kaltpilgerdorn (1) an seinem freien Ende einen koaxial drehbar gelagerten Verlängerungsstopfen (4) auf, in den das Negativ der herzustellenden gewendelten Innenverrippung eingearbeitet ist.

Figure 00000001
The invention relates to a cold pilger tool for the production of internally ribbed tubes according to the cold pilger step method in a rolling stand which can be moved back and forth in the rolling direction and has tapered rollers which roll over the rolling stock with an alternating direction of rotation, in which a likewise tapering cold pilger mandrel is located. The cold pilgrim mandrel (1) has at its free end a coaxially rotatably mounted extension plug (4) into which the negative of the coiled internal ribbing to be produced is incorporated.
