Specially-shaped single-wire positioning device for producing flexible aluminum stranded wire

Abstract

The invention discloses a specially-shaped single-wire positioning device for producing a flexible aluminum stranded wire, which is characterized in that: a positioning mechanism is arranged in front of a guide mechanism to guide and position a specially-shaped single wire in advance and then guide and transmit the specially-shaped single wire. The positioning device can supply large tensile force, so the specially-shaped single wire is unable to overturn or to jump in a gap between a wire-passing guide wheel body on the premise that the single wire is not thinned and the surface of the single wire is not damaged, the specially-shaped single wire with the cross section being in a trapezoid shape which is easy to overturn and jump during the transmission process can be well guided and positioned, the overturning or jumping situation of the specially-shaped single wire can be avoided during the transmission process, the flexible aluminum stranded wire can reach the effects such as roundness, compactness and smoothness after being stranded, and the production quality of the flexible aluminum stranded wire is improved. The positioning device has a simple structure, is convenient to operate, has good practicability, and can also avoid the increment of the production cost caused by adding production equipment of novel products.

Description

technical field [0001] The invention relates to a special-shaped monofilament positioning device for producing annealed aluminum stranded wire. Background technique [0002] With the sustained and rapid development of the national economy, my country's demand for electricity has also increased sharply, and the power transmission line is required to develop in the direction of high current and ultra-high voltage, which requires the continuous increase of the transmission capacity of the transmission line. Under the circumstances of the continuous extension of the Three Gorges transmission line, west-to-east power transmission, north-south mutual supply, and the urgent need for renovation of old lines that have been in operation for decades, my country urgently needs to build a safe and reliable power grid that can meet the needs of industrial and agricultural development. Conservation grid. In the capacity expansion and reconstruction project, if the entire line is rebuilt...

Problems solved by technology

However, the key technology for the production of annealed aluminum stranded wires lies in the stranding of annealed aluminum single wires. In this process, it is necessary to avoid abnormalities such as thinning, scratches, turning over, and jumping wires during the stranding process of annealed aluminum wires, especially The problem of turning over and jumping wires. The annealed aluminum single wire of this product is more prone to turning over and jumping during the transmission process than ordinary special-shaped single wires, which affects the overall quality of the annealed aluminum stranded wire to a certain extent. , it is particularly necessary to develop a heterosexual monofilament positioning device that can prevent the trapezoidal soft aluminum single wire from turning over and jumping during its transmission process
