Twisted wire die cavity is divided into three sections, and centre is straightway, and two sections connect with incoming line, line outlet are all internal conical surface, middle straight line
Section be diameter it is smaller press twisted section, towards the part of incoming line be twisted wire section, the part towards line outlet is line segment；It twists
The internal conical surface of line segment is arc internal conical surface, and the internal conical surface for going out line segment is straight line internal conical surface；The cylindrical die master
Body is made of upper die and lower die split, and upper die and lower die are semi-cylindrical module, and upper die and lower die are symmetrically arranged in three sections of recess
Chamber, three sections of concave internal cavities are respectively semicircular arc internal conical surface, semicircle groove face, semicircle straight line inner conical surface, semicircular arc inner circle
The conical surface, semicircle groove face, semicircle straight line inner conical surface respectively split be arc internal conical surface into line segment, straightway press it is twisted
Section, straight line inner circle inner conical surface go out line segment；
It is described go out line segment and press twisted section junction have step；
Each section of junction is uniformly that arc transition connects；
The position that the inlet wire section is located at incoming line is provided with the protection groove being relatively large in diameter；
Groove is provided in the upper mold mating surface in an axial direction, is provided with protrusion in lower die mating surface in an axial direction and can be with
The adaptable limit ribs of upper mold axial notch；
The groove, limit ribs cross sectional shape are triangle；
The upper die and lower die material is W6Mo5Cr4V2 steel.
The alloy cable conductor strand mold of the present invention, die main body close 1+5 into line segment by arc internal conical surface
Golden cable core squeeze and tentatively twisted, and the cable core with rectangular section, which is extruded, to be twisted as after arc-shaped core,
By stage casing press twisted section 1+5 alloy cables core press be twisted for intermediate round, outer ring sector 1+5 cores at
Cable, by protecting groove that die main body outer ring matrix is prevented to be worn, the inlet wire of arc internal conical surface is helped and middle straight line section
Press twisted section to connect by arc transition, not easy to wear into line segment working face, maintenance load is small, and straightway can also be made
For into the repair surplus of line segment, so as to being repaired into line segment, easy to maintenance, service life is long.

Specific implementation mode
As shown, a kind of alloy cable conductor strand mold includes cylindrical die main body, have inside die main body
Central through hole constitutes twisted wire die cavity, and die main body one end is incoming line, and the other end is for line outlet；Die main body inner strands mould
Chamber is divided into three sections, and centre is straightway, and two sections connect with incoming line, line outlet are all internal conical surface, middle straight line Duan Weizhi
Diameter it is smaller press twisted section 4, towards the part of incoming line be twisted wire section 5, the part towards line outlet is line segment 3；Twisted wire
35 internal conical surfaces of section are arc internal conical surface, and it is straight line internal conical surface to go out 3 internal conical surface of line segment；The cylindrical die main body by
1 lower die 2 of upper mold, which is closed, to be constituted, and 1 lower die of upper mold is semi-cylindrical module, and upper die and lower die are symmetrically arranged with three sections of concave internal cavities, three sections
Concave internal cavity is respectively semicircular arc internal conical surface, semicircle groove face, semicircle straight line inner conical surface, semicircular arc internal conical surface, half
Split is that arc internal conical surface into line segment 5, straightway presses twisted section 4, straight respectively for round recessed face, semicircle straight line inner conical surface
Line inner circle inner conical surface goes out line segment 3.
Going out line segment 5 and pressing 4 junction of twisted section has step, press it is twisted after the completion of alloy cable core will not be by
The rough surface for going out line segment 5 includes flower, and die main body basis material decreases abrasion.
