Background technology
At present, the aluminium stranded conductor cable that superhigh pressure and UHV transmission cable adopt the carbon fiber reinforce plastic core to replace steel core to manufacture, save 30% steel core than steel reinforced aluminium conductor, and there are the combination properties such as high strength, high anti-corrosion, anti-creep, its cost is low, lightweight, is energy-conservation, material-saving, the product of save land (saving the transmission of electricity corridor).
Carbon fiber reinforce plastic core aluminum stranded wire cable, need to be wrapped in core with anti-aging by carbon fiber closely by outer field metal material wire, and there is space in the circular cross-section wire after the strand system, can not meet the specification requirement of carbon fiber reinforce plastic core aging-resistant.Particularly, the circular cross-section wire is formed effective conductive section area minimum in the twisted pair cable outer ring, according to kelvin effect, and its conductive capability minimum.
After the plain conductor cross sectional shape is changed into to fan-shaped, prismatic, S shape and other various odd-shaped cross sections, between wire, arrange closely, through the strand system with after pressing, form the conductor layer of tight parcel in carbon fiber reinforce plastic core outside, tight almost, not only conductive capability promotes, and has met the specification requirement of carbon fiber reinforce plastic core aging-resistant.
Yet the difficulty of manufacturing the odd-shaped cross section wire is very large, can not adopt conventional drawing equipment, even circular stretching die is replaced by special-shaped stretching die, after drawing, the wire angle is not full, and cross sectional shape is also defective, can not reach the technical standard of wire.All adopt at present extrusion process to manufacture the odd-shaped cross section wire both at home and abroad; with metal extrusion press, suppress; its shortcoming is; metal extrusion press is not the electric wire production equipment special; but a kind of alternate device; it is very low that it goes out linear velocity; can not be equipped with automatic wire-collecting machine; can only adopt the take-up of single-deck take-up mode, take-up efficiency is low, while manually changing dish after take-up, must shut down; production process is intermittently; i.e. compacting, take-up is cyclic variation, can not form continuous flow production line, can't be supporting with existing electric wire cable flow production line.Particularly extruder is uncontrollable to upset and the torsional deformation of wire, unstable product quality.
Summary of the invention
The purpose of this utility model is in order to overcome the above-mentioned defect in odd-shaped cross section wire manufacture processing, a kind of process equipment of odd-shaped cross section wire is provided, to guarantee product quality, increase substantially production efficiency, meet the manufacture of the required carbon fiber reinforce plastic aluminium stranded conductor of superhigh pressure and UHV transmission cable.
Realize that the technical solution of the utility model is: the process equipment of a kind of cross section wire, it comprises tensile part, rolled parts and orthopaedic component, and described tensile part is circular stretched film, and described rolled parts is roll-box; The roll-box mounting structure of described rolled parts is identical with the mounting structure of the circular stretched film of tensile part, and roll-box and circular stretched film capable of interchanging positions are installed.
The roll-box of described rolled parts is transverse rolling roll-box or the perpendicular roll-box that rolls.
Described rolled parts is by two similar transverse rolling roll-boxes of series connection or perpendicularly roll roll-box and form.
The circular stretched film of described tensile part is many combinations.
The circular stretched film of described tensile part is preferably 8 combinations.
Described orthopaedic component is special-shaped sizing die or circular sizing die.
The front end of described tensile part, rolled parts is equipped with actinobacillus device, and the rear end of described orthopaedic component is equipped with take-up.
Described actinobacillus device is the double actinobacillus device.
Described take-up is the Full-automatic double-deck take-up.
Described Full-automatic double-deck take-up adopts guide wheel track following wire arranging and collecting device.
The utility model adopts the drawing of interchangeable combination and rolling to combine and manufactures the odd-shaped cross section wire, in the wire production line, and available following several concrete compound modes:
1. first with the multistage stretching mould, the wire pole stock is drawn into to the circular cross-section wire, makes the sectional area of its sectional area and shaped conductor close, and then roll into odd-shaped cross section with the special-shaped slot roll, finally use special-shaped stretching die shaping.
2. first with the special-shaped slot roll, the wire pole stock is rolled into to odd-shaped cross section, then use multistage special-shaped stretching die drawing, its sectional area is met the requirements.
3. with multistage special-shaped slot roll rolling wire pole stock, until sectional area meets the requirements, finally use special-shaped stretching die shaping.
4. use the multi-stage circular grooved roller by wire pole stock rolling circular cross-section wire, make the sectional area of its sectional area and shaped conductor close, and then roll into odd-shaped cross section with the special-shaped slot roll, finally use special-shaped stretching die shaping.
The beneficial effects of the utility model are:
1, after the circular cross-section pole stock rolls by the stretching of multiple tracks circular die or multiple tracks circular recess roll, the sectional area of wire has approached the sectional area of odd-shaped cross section wire, compression ratio while entering the roll-box rolling is little, the angle that can guarantee wire after the twice rolling is full, cross sectional shape meets specification requirement, after the shaping of odd-shaped cross section drawing mould, the surface smoothness of wire improves again, and cross sectional shape meets specification requirement fully.
2, because the operation of rolling is continuous, the miscellaneous equipment of roll-box and production line is supporting, meets the requirement of wire Production line, goes out linear velocity fast, and production efficiency is high.
3, roll-box is independently parts, with stretching die, can exchange, while manufacturing the odd-shaped cross section wire, roll-box is arranged on the die holder of circular stretching die, remove roll-box and set up the bracing wire mould, can manufacture the circular cross-section wire, realized a tractor serves several purposes, user's production cost reduces, and has great economic benefit.
4, adopt guide wheel track following winding displacement technology in the Full-automatic double-deck take-up, guaranteed the equidirectional dense arrangement of shaped conductor fully, and controlled upset and torsional deformation.
Below in conjunction with example in detail the utility model.
