Abstract

The invention discloses a multi-drawing-wire conductor wire-stranding method. The method includes the working procedure of wire drawing and the working procedure of wire stranding. According to the wire drawing working procedure, a plurality of metal wires are formed by drawing on a multi-wire drawing machine in a one-time mode, and the formed metal wires are combined into a strand of metal wires which is wound on a bobbin; according to the wire stranding working procedure, a plurality of strands of metal wires are stranded on a wire stranding machine in a one-time mode, and the strands of metal wires after the stranding are combined into a metal conductor which is wound on a bobbin. The product produced with the method is round and normal in appearance, good in flexibility and reduced in outer diameter, and the method saves raw material and labor, reduces production field area and energy consumption and promotes production efficiency.

Description

Many-headed wire conductor twisted wire method

(1) technical field:

The present invention relates to the processing technology of metallic conductor wire rod, be specially a kind of many-headed wire conductor twisted wire method.

(2) background technology:

The traditional production method of many one metal wires twisted wire is that a wire-drawing equipment draws an one metal wire, a Wire winding shaft is received an one metal wire, tens even hundreds of root and above wire will be twisted into a metallic conductor, just must restraint first strand to the wire of single wire drawing take-up once, even bundle strand twice, three times, and then the wire strand that will restraint in advance strand is made the metal flexible conductor at stranding machine.

The problem that tradition twisted wire method exists:

1, operation is many, and personnel are many, and production efficiency is low.

2, the external diameter of conductor is large, and flexibility is poor.

3, insulating material and sheath material consumption are many.

4, because wire drawing, the take-up of many one metal wires carried out respectively, and the tension force of generation is inconsistent, cause the problem such as follow-up bundle twisted wire is jumped strand, back of the body thigh, burr, fracture of wire and can't normally produce.

(3) summary of the invention:

For the deficiency of conventional art, a kind of high productivity, performance is good, cost is low many-headed wire conductor twisted wire method have been the objective of the invention is to propose.

Can realize the many-headed wire conductor twisted wire method of above-mentioned purpose, comprise wire drawing and twisted wire two large process, difference is that described wire-drawing process is that many one metal wires once draw respectively moulding on wire drawing machine, and the many one metal wires after the moulding synthesize one metal wire and use the bobbin rolling; Described wire stranding is that the multiply metal wire is disposable stranded on stranding machine, and the multiply metal wire after stranded synthesizes a strip metal conductor and uses the bobbin rolling.

For making in the stranded process each strand metal wire stressed evenly, in wire-drawing process, wire radical and wire diameter in the described per share metal wire are identical.

For realizing many-headed wire, described wire drawing machine adopts multistation wire drawing machine.

Advantage of the present invention:

1, many-headed wire conductor twisted wire method of the present invention has solved the fracture of wire that occurs without the direct twisted wire of bundle strand wire, burr and rounding problem not, satisfies normal production requirement.

2, product appearance rounding, the pliability that adopts the present invention to produce is good, external diameter reduces more than 5%, saves raw material.

3, adopt production technology of the present invention, lack 2 procedures than traditional handicraft, save production site, the energy resource consumption more than 3 times, the manpower more than 3 times more than 4 times, improve the production efficiency more than 3 times.

4, production technology of the present invention can be widely used in the production of metallic conductor, mainly applies to the production of electric wire flexible conductor.

(5) embodiment:

Below in conjunction with accompanying drawing technical scheme of the present invention is described further.

Many-headed wire conductor twisted wire method of the present invention comprises wire-drawing process and wire stranding.

1, described wire-drawing process is that many one metal wires 1 once draw respectively moulding on multiple drawing machine 2, and the many one metal wires 1 after the moulding synthesize one metal wire 3 and use bobbin 6 rollings.

As shown in Figure 1, after four volume wires 1 unreeled, guide wheel 7 guiding by separately corresponding setting entered wire-drawing die corresponding on the multiple drawing machine 2 and draw moulding (wire diameter is identical), four one metal wires 1 after the drawing moulding are unified through a guide wheel 7 guiding, at last by bobbin 6 rollings.

2, described wire stranding is that multiply metal wire 3 is disposable stranded on stranding machine 4, and the multiply metal wire 3 after stranded synthesizes a strip metal conductor 5 and with bobbin 6 rollings.

As shown in Figure 2, after four volume metal wires 3 unreel, by the corresponding guide wheel that arranges 7 guiding separately, enter the stranded mould strand system on the stranding machine 4, four wires 3 after the strand system synthesize a metallic conductor 5, after guide wheel 7 guiding by bobbin 6 rollings.

The metallic conductor 5 that adopts the technology of the present invention to produce, space between wherein the wire 1 and wire 1, between metal wire 3 and the metal wire 3 is tight, so reduced diameter of metallic conductor 5, flexibility increases, the outward appearance rounding, save insulating material and sheath material, shown in Fig. 3 (a), Fig. 3 (b).
