Abstract
The utility model relates to a combination of a precision metal material applied to a cable and an extrusion device thereof. The combination is composed of the precision metal material applied to the cable and the extrusion device. The precision metal material applied to the cable is formed by stranding strands of wires, and the cross section is circular. The combination of the precision metal material applied to the cable and the extrusion device thereof is formed by stranding seven main wires, six edge gap wires and three intermediate gap wires. The extrusion device is composed of an active extrusion wheel and a passive extrusion wheel. The active extrusion wheel and the passive extrusion wheel of the extrusion device jointly extrude the precision metal material applied to the cable. The combination provided by the utility model has the advantages that the compactness of the metal material is effectively improved; the conductivity of the metal material applied to the cable is improved; and the edge smoothness of a metal wire stranded structure is effectively improved.
Description
Technical field
The utility model relates to cable technology field, relates to or rather a kind of precision metallic material for cable and pressurizing unit combination thereof.
Background technology
Cable metal material is to be that circular metal wire rod spiral winding is made by many sliver transvers sections, and by extrusion die, multiply metal wire rod is extruded distortion, twists cross section processed and be the strand structure processed of the shapes such as fan-shaped, watt shape, circle.Circular metal wire rod strand is built in together, in the middle of adjacent wire rod, can there is space, because space can cause metal wire rod chap, the outer jacket that outside needs and the material usage of armour also increase thereupon, cause cable to become heavy and chap, improve cable cost, improved logistics cost, increased difficulty of construction.On the other hand, in the middle of adjacent wire rod, can there is space, also can hinder electric current flowing between adjacent wire, weaken the electric conductivity of metal material.
Edge at cable with metal material, the cross section of metal wire rod is rounded, and edge just there will be the irregularly shaped of fluctuating, and in high-tension environment for use, the projection at edge easily causes point discharge, causes accident.
As can be seen here, above-mentioned existing cable still has many defects with metal material, and is urgently improved.
Because the defect that above-mentioned existing cable exists with metal material, the design people is based on being engaged in this type of product design manufacture for many years, amass and have abundant practical experience and professional knowledge, positive research and innovation in addition, to founding a kind of precision metallic material for cable and pressurizing unit combination thereof, make it have more competitiveness.Through constantly research, design, and after repeatedly studying sample and improving, finally create the utility model having practical value.
Summary of the invention
Technical problem underlying to be solved in the utility model is, overcome the defect that existing cable exists with metal material, and provide a kind of precision metallic material for cable and pressurizing unit thereof to combine, overcome existing cable and had the up-and-down defect in space and edge with metal material, improved tightness degree, electric conductivity and the smooth of the edge degree of metal material for cable.
The utility model solves its technical problem underlying and realizes by the following technical solutions.According to the precision metallic material for cable the utility model proposes and pressurizing unit combination thereof, by precision metallic material and pressurizing unit for cable, formed, precision metallic material for cable is comprised of strand wire strand system, cross section is rounded, precision metallic material and pressurizing unit thereof for cable combine by seven electric mains, six roots of sensation edge voids electric wire and three intermediate gaps electric wire strand systems form, electric main cross section is rounded, intermediate gaps wire cross-section is triangular in shape, adjacent three electric mains six existence surround the position, space forming, in the middle of the position, three spaces of continuous adjacent, be filled with respectively three intermediate gaps electric wires, edge voids electric wire ovalize, edge voids electric wire is positioned at the position, space of the electric main of adjacent two edges edge, pressurizing unit is comprised of active squeegee roller and passive squeegee roller, initiatively between squeegee roller and passive squeegee roller, there is space, passive squeegee roller is close to middle four electric mains that are filled with respectively three intermediate gaps electric wires in position, space, initiatively squeegee roller is close to middle two electric mains of not filling intermediate gaps electric wire in position, space, the common extruding of the active squeegee roller of pressurizing unit and passive squeegee roller is for the precision metallic material of cable.
Precision metallic material for cable described in the utility model and pressurizing unit combination thereof, the beneficial effect of its generation is: adopt the position, space of the electric main of edge voids wire pair adjacent two edges edge to fill, effectively improved the smooth of the edge degree of metal wire rod strand structure processed, because cross section is rounded, in strand extrusion process processed, the position deformation that half girth of circular cross section is corresponding is less, and the main deformation effect power of extruding is from the direction of circular second half girth of cross section, the malleation direction of squeegee roller initiatively namely, in the middle of the position, three spaces of continuous adjacent, be filled with respectively three intermediate gaps electric wires, this is with regard to a semi-perimeter of corresponding circular cross section, this semi-perimeter is close to passive squeegee roller, the deformation that this semi-perimeter is subject to is less, in the middle of the position, three spaces of the continuous adjacent of vacating in addition, be not filled with intermediate gaps electric wire, this is with regard to second half girth of corresponding circular cross section, this semi-perimeter is subject to the initiatively squeezing action of squeegee roller, deformation is larger, therefore, the position, space of vacating just provides the space of distortion for compressional deformation, be conducive to the become inner tight of each wire in extrusion process.
