Description

Verfahren zur Herstellung drallarmer Drahtseile aus Drahtlitzen Bei der Verseilung von Drähten zu Drahtlitzen oder Drahtseilen werden die Drähte schraubenförmig um die Seele der Litzen herumgewunden. Dadurch entsteht im Draht eine Spannung und das Bestreben, in seine ursprüngliche gestreckte Lage zurückzufedern. Es ist bereits vorgeschlagen worden, die Drähte bei der Herstellung der Litzen vor dem Verseilen derart in die Schraubenform vorzubiegen, daß die Rückfederkraft der einzelnen Drähte aufgehoben ist. Würde man bei der Herstellung von Litzenseilen aus derart behandelten Litzen auch jede einzelne Litze einer gleichen Behandlung unterziehen, so würden die Einzelelemente durch die zweimalige Vorformung Beanspruchungen ausgesetzt, die für das fertige Litzenseil nachteilig wären.Process for the production of low-twist wire ropes from wire strands Bei the stranding of wires to wire strands or wire ropes, the wires become helical wound around the soul of the strands. This creates tension in the wire and the effort to spring back into its original stretched position. It is already It has been proposed to use the wires in the manufacture of the strands prior to stranding bend into the helical shape in such a way that the resilience of the individual wires is canceled. Would one be treated in this way in the manufacture of stranded ropes If strands would also subject each individual strand to the same treatment the individual elements are exposed to the stresses caused by the two-time preforming would be disadvantageous for the finished stranded rope.

Erfindungsgemäß sollen die Litzenseile, die vor dem Verseilen vorgebogen werden, aus unvorgeformten Drähten bestehen. Es werden also bei der Herstellung der Litzen die einzelnen Drähte der Litze selbst nicht vorgebogen. sondern zunächst in der üblichen Weise miteinander verseilt. Erst die aus den Einzeldrähten zusammengeschlagenen Litzen sollen, bevor sie zum Seil zusammengeschlagen «-erden, in diejenige Schraubenform vorgebogen werden, welche sie im fertigen Seile einnehmen sollen. Derart hergestellte Litzenseile sind, obwohl die Einzeldrähte der Litze nicht vorgebogen sind, äußerst drallarm, und nach dem Aufschneiden springen weder die Litzen aus den Seilen noch die Einzeldrähte aus den etwa abgewickelten Litzen. Die nach dem erfindungsgemäßen Verfahren hergestellten Litzenseile haben gegenüber solchen, bei deren Herstellung auch die Einzeldrähte durch Vorbiegevorrichtungen behandelt worden sind, den Vorteil, daß einerseits die einzelnen Drähte infolge der einmaligen Vorformung nur einmal beansprucht werden, daß ferner infolge der Verringerung der Vorbiegevorrichtungen das Verfahren vereinfacht wird. Durch die Verringerung der Formmittel wird auch die Oberfläche der Einzeldrähte geschont, was namentlich bei der Verseilung verzinkter Drähte beachtlich ist. Infolge des Fortfalls der Vorbiegung der Einzeldrähte weisen derartig gefertigte Litzenseile eine geringere Federungsmöglichkeit auf, die sich bei der Benutzung von Litzenseilen für bestimmte Anwendungszwecke als vorteilhaft erwiesen hat.According to the invention, the stranded ropes that are pre-bent before stranding consist of unformed wires. So there will be in manufacturing of the strands, the individual wires of the strand itself are not pre-bent. but first stranded together in the usual way. First the ones that were tied together from the individual wires Before they are tied together to form a rope, strands should be screwed into the shape of a screw be pre-bent, which they should take in the finished rope. Manufactured in this way Stranded ropes, although the strands of the strand are not pre-bent, are extreme There is little twist and after cutting the strands neither jump out of the ropes nor the individual wires from the roughly unwound strands. According to the invention Method manufactured stranded ropes have compared to those in their manufacture the individual wires have also been treated by pre-bending devices, the advantage that on the one hand the individual wires only once as a result of the one-time preforming claimed that further as a result of the reduction in prebending devices the procedure is simplified. By reducing the mold means will also the surface of the individual wires is spared, which is particularly the case when stranding is galvanized Wires is considerable. As a result of the discontinuation of the pre-bending of the individual wires stranded ropes manufactured in this way have a lower possibility of suspension, which when using stranded ropes for certain purposes as advantageous has proven.

PATENTANSPRUCH: Verfahren zur Herstellung drallarmer Drahtseile aus Drahtlitzen, dadurch gekennzeichnet, daß aus unvorgebogenen Drähten zusammengeschlagene Litzen vor der Verseilung zum Litzenseil in diejenige Schraubenform vorgebogen werden, die sie im fertigen Litzenseil einnehmen. PATENT CLAIM: A process for the production of low-twist wire ropes from wire strands, characterized in that strands folded together from non-pre-bent wires are pre-bent into the helical shape that they assume in the finished stranded rope before being stranded to form the stranded rope.
