Technical field
The utility model belongs to flexible conductor production and processing technical field, more particularly, relates to a kind of flexible conductor and presses mould.
Background technology
In medium and high voltage cable or conductor production, in order to increase its withstand voltage properties, conductor is all done circular, and in the production process of cable conductor, do multilayer according to cross-sectional sizes presses, can under same outer diameter as, allow like this stranded conductor cross section to greatest extent near the cross section of solid conductor, strengthen the electric conductivity of conductor, make cable outward appearance rounding.But in the prior art, the existing external diameter that presses the conductor after the Mould Machining is more open, and quality can not guarantee.
The utility model content
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, provide under a kind of prerequisite not affecting flexible conductor resistance, can dwindle to greatest extent the flexible conductor external diameter, make the conductive surface rounding, the ganoid flexible conductor of insulated electric conductor presses mould.
Solve above-described technical problem, the technical scheme that the utility model is taked is:
The utility model is that a kind of flexible conductor presses mould, comprise the synnema sizing die that flexible conductor is carried out shaping, flexible conductor is carried out the strand adpressing mould of twice stranding, the dual-side of described synnema sizing die arranges respectively bell-mouth structure of air I and bell-mouth structure of air II, described bell-mouth structure of air I and bell-mouth structure of air II are communicated with the shaping hole at synnema sizing die center respectively, and described strand adpressing mould adopts the wolfram steel material to make.
The hole is pressed in the upper setting of described strand adpressing mould, strand adpressing mould both sides arrange respectively bell-mouth structure of air III and bell-mouth structure of air IV, pressing the hole is communicated with bell-mouth structure of air III and bell-mouth structure of air IV respectively, the angle of described bell-mouth structure of air III is 60-90 °, and the angle of bell-mouth structure of air IV is 55-65 °.
The angle of described bell-mouth structure of air I is 55-65 °, and the angle of bell-mouth structure of air II is 60-90 °.
When described synnema sizing die carries out the flexible conductor shaping, the internal diameter in the shaping hole of synnema sizing die is set to diameter dimension less than the structure of flexible conductor, described strand adpressing mould carries out flexible conductor when pressing, and the internal diameter that presses the hole is set to diameter dimension less than the structure of flexible conductor.
Adopt the technical solution of the utility model, can obtain following beneficial effect:
Flexible conductor of the present utility model presses mould, under the prerequisite that does not affect flexible conductor resistance, can dwindle to greatest extent the flexible conductor external diameter, makes flexible conductor surface rounding, the insulated electric conductor smooth surface.
Through the flexible conductor that twisted wire tungsten steel die of the present utility model presses, the finished product external diameter of flexible conductor is rounding more, and distortion is little behind the one-tenth dish.
