Abstract
The utility model relates to a preforming device for processing electric wire cables, particularly a new strand pre-twisting device, which comprises a twisting cage, a set of pre-twisting discs arranged on a twisting cage axle and pre-twisting guide wheels evenly distributed on the pre-twisting discs. The utility model is characterized in that the number of the pre-twisting guide wheels is the whole number time of six and the pre-twisting guide wheels are movably arranged on the circumferential edge of the pre-twisting discs by a radial moving device. A coaxial wire dividing disc is arranged in front of a first pre-twisting disc and the wire dividing disc is provided with wire dividing holes. The utility model has the advantages of simple structure, and convenient and uniform pre-twisting adjustment. The utility model solves a single wire rebounding problem and a strand loosening problem. Meanwhile, the utility model overcomes the problems that conducting wires are easy to be abraded and aluminum powder is relatively large. The quality and the qualified rate of products are increased.
Description
Technical field
The utility model relates to a kind of pre-shaping device of electric wire processing, specifically a kind of novel twisted wire pre twist.
Background technology
Along with the develop rapidly of Chinese national economy, energy demand is increasing.The deficiency of electric power resource and distribution imbalance have seriously hindered development and national economy.China's water conservancy and coal resources focus mostly in the west area, and corresponding electric power resource concentrates on also that population is few, the west area of economics of underdevelopment.And densely populated, economically developed middle part and eastern region electric power resource wretched insufficiency.Therefore realize that " transferring electricity from the west to the east " is the grand strategy of Chinese national economy development.The country that China is again rivers and lakes, high mountain gorge is numerous will realize this grand strategy, must use high standard, high-quality cable.In realizing big capacity, long distance power transmission process, must select the heavy in section, cross over lead greatly.Heavy in section (400mm
2More than), the big cable conductor of crossing over (more than 2000 meters) generally adopts steel core aluminium and aluminium alloy conductors steel.Particularly aluminium alloy conductors steel has remarkable advantages in aerial condutor, and it mainly shows because intensity is big, in light weight, can strengthen the stringing span, reduces the column foot number; Or reduce tower bar height, reduce whole project cost.Therefore this cable conductor is subjected to the welcome of power industry deeply.But the cable of producing this high-quality, high standard is had higher requirement to production technology and equipment.Production heavy in section, the big steel core aluminium alloy cable twisted wire of crossing over, because its line diameter is thick, length is big, the general employing has back twist and two kinds of stranding machines of no back twist.The product that has the back twist stranding machine to produce is tight, docile, but speed of production is slow, production efficiency is low; No back twist stranding machine speed of production is fast, production efficiency is high, but the twisted wire of producing has the phenomenon that rebounds with loose strand.So the twisted wire that how to solve the production of no back twist stranding machine has a rebound and the phenomenon of pine thigh, is the technical problem that those skilled in the art needs to be resolved hurrily.In order to address the above problem, the technical staff of the industry had increased twisted wire pre twist (as shown in Figure 1) before no back twist stranding machine, its twisted pair wire has a rebound and the phenomenon of pine thigh is alleviated to some extent, but effect is unsatisfactory, still has a rebound easily during especially for stranded high-strength aluminum alloy single line and the phenomenon of pine strand.Therefore inventing a kind of novel twisted wire pre twist, is very useful for wires and cables industry.
The utility model content
Technical problem to be solved in the utility model is: the defective at existing product exists, a kind of novel twisted wire pre twist is provided, and the product that it has solved the production of existing no back twist stranding machine has a rebound and the phenomenon of pine strand easily.
The technical solution of the utility model is achieved in that it comprises the strand cage, is contained in one group of pretwist dish on the strand cage axle and is evenly distributed on pre-twisted guide wheel on the pretwist dish, it is characterized in that: the number of pre-twisted guide wheel is 6 integral multiple, it is by moving radially the circumferential edge that the device activity is contained in pretwist dish 2, coaxial noseplate is equipped with in the front of first pretwist dish, has the separated time hole on the noseplate.Coaxial branch wire carrier also is equipped with in the front of described noseplate; The number of described pre-twisted guide wheel is 6,12,18,24,30,36, preferred 24; The described device that moves radially comprises the wheel frame groove that is fixed on the pretwist dish, be with adjustable wheel frame on the wheel frame groove, the upper end of adjustable wheel frame is provided with draw-in groove, and draw-in groove is connected with adjusting bolt on the wheel frame groove, by rotation axis guide wheel is housed in the perforate in the middle of the adjustable wheel frame.
The utlity model has simple and reasonablely, the adjusting of pretwist is more convenient, advantage of uniform more, and it has solved the problem of single line bounce-back, pine strand, has overcome the lead relative more problem with aluminium powder of scratch easily simultaneously, has improved the quality and the qualification rate of product.
