Description

Verfahren zur Herstellung gebogener Profileisen Die Erfindung bezieht sich auf ein Verfahren zur Herstellung gebogener Profileisen, bei dem das Profileisen unmittelbar nach dem Verlassen der Walzenstraße in waagerechter Ebene fortlaufend gebogen und dabei nach einer Schraubenlinie aufgewickelt wird.Method for the production of bent profile iron The invention relates on a process for the production of bent profile iron, in which the profile iron immediately after leaving the roller train continuously in the horizontal plane is bent and wound up along a helical line.

Manche Profile, beispielsweise I-Eisen mit dünnem Steg, erfahren beim Aufwickeln eine unerwünschte Verformung, beispielsweise ein Einknicken des Steges; um dies zu verhindern, müssen an der oder hinter der BieZemaschine besondere Vorrichtungen, beispielsweise ein Rollenpaar, angebracht werden, die aber ein einwandfreies Aufwickeln des ganzen Profilstabes nicht gestatten.Some profiles, for example I-irons with a thin web, learn from Winding up an undesirable deformation, for example buckling of the web; To prevent this, special devices must be installed on or behind the BieZ machine, For example, a pair of rollers, can be attached, but they allow proper winding of the entire profile bar.

Gemäß der Erfindung wird diese Schwierigkeit dadurch behoben, daß nicht der ganze Profilstab aufgewickelt wird, sondern die gewünschten Bogenlängen schon abgeschnitten werden, bevor das vordere Ende des Profilstabes eine volle Windung beschrieben hat.According to the invention, this problem is overcome in that not the entire profile bar is wound up, but the desired arc lengths be cut off before the front end of the profile bar is a full turn described.

Das Abschneiden der Bogenstücke kann ,entweder mit einer fliegenden Schere oder mit einer ebensolchen Säge ausgeführt werden, ohne daß der Biegevorgang unterbrochen wird, oder @es kann der Biegevorgang jeweils nach dem Biegen einer bestimmten Kreisbogenlänge unterbrachen werden, um das Abschneiden der Bogenstücke zu ermöglichen.Cutting off the bow pieces can be done, either with a flying Scissors or a saw can be performed without the bending process is interrupted, or @ it can be the bending process after each bending of a certain circular arc length are interrupted in order to cut off the arc pieces to enable.

Das Verfahren der Erfindung gestattet auch, das Aufwickeln nach einer Schraubenlinie, das die Wiederbeseitigung der Verwindung des abgeschnittenen Bogenstückes erforde lich macht, überhaupt zu vermeiden und das Profileisen unmittelbar nach einer Kreislinie, also meiner Ebene, zu biegen.The method of the invention also allows winding after a Helical line that eliminates the twisting of the cut piece of arch It is necessary to avoid at all and the profile iron immediately after a circular line, i.e. my plane, to bend.
