Abstract
The utility model discloses a kind of special-shaped wire-drawing die tool, comprise cylindricality die sleeve, in cylindricality die sleeve, there is core rod, there is in core rod wire drawing passage, one end of wire drawing passage has incoming line, and the other end has line outlet, and the cross section of described wire drawing passage is in watt shape, its bore gradually diminishes from incoming line to line outlet, and described cylindrical die puts the backstay being fixedly equipped with and overlapping axes normal with this cylindrical die.Adopt the special-shaped wire-drawing die tool of said structure, the special-shaped monofilament of watt shape can be drawn out, with common wire drawing machine with the use of time only need on wire drawing machine die holder, offer the bar-shaped trough matched with backstay, the backstay that cylindrical die puts matches with the bar-shaped trough on wire drawing machine die holder can prevent rotation of the present utility model in drawing process, there will not be the conductor monofilament distortion drawn out, improve the qualification rate of product, ensure that the quality of product.The utility model need not draw by special special drawing machine, and structure is simple, greatly can reduce the production profile conductor monofilament cost of enterprise.
Description
Technical field
The utility model relates to a kind of wire-drawing die, specifically relates to a kind of special-shaped wire-drawing die tool for the preparation of profile conductor core in cable.
Background technology
Along with the develop rapidly of cable industry, in order to reduce cable cost, ensureing cable presentation quality, ensureing cable performance parameter, cable conductor has entered variation and has produced.Current most enterprise be by twisted wire after conductor become fan-shaped or watt shape from circle, reduce the space between cable conductor, thus reduce cable finished product external diameter, both cost had been saved, also be convenient to install, but the method creates work hardening when twisted wire to conductor, have a strong impact on the performance of cable, greatly reduced its electric conductivity.A kind of way is also had to be, in wire-drawing process process, conductor is directly made circular monofilaments, again through a die mould process, then twisted wire, or be directly processed into special-shaped monofilament by pressing mold at wire stranding, the method reduces production efficiency on the one hand, the easy fracture of wire or stand up when wire stranding in addition, and work hardening is created to monofilament, have impact on monofilament resistivity, cause stranded after conductor resistance performance be deteriorated.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of special-shaped wire-drawing die tool that directly can draw out profile conductor monofilament.
For solving the problems of the technologies described above, a kind of special-shaped wire-drawing die tool of the utility model, comprise cylindricality die sleeve, in cylindricality die sleeve, there is core rod, have wire drawing passage in core rod, one end of wire drawing passage has incoming line, and the other end has line outlet, the cross section of described wire drawing passage is in watt shape, and its bore gradually diminishes from incoming line to line outlet.
Adopt the special-shaped wire-drawing die tool of said structure, because the cross section of described wire drawing passage is in watt shape, its bore gradually diminishes from incoming line to line outlet, when conductor draws drawing conductor monofilament through wire drawing passage of the present utility model by wire drawing machine, the shape of conductor monofilament is consistent with the shape of wire drawing channel cross-section, is also the special-shaped monofilament of watt shape.
As further improvement of the utility model, described cylindrical die puts the backstay being fixedly equipped with and overlapping axes normal with this cylindrical die.
Adopt the special-shaped wire-drawing die tool of said structure, because described cylindrical die puts the backstay being fixedly equipped with and overlapping axes normal with this cylindrical die, with common wire drawing machine with the use of time only need on wire drawing machine die holder, offer the bar-shaped trough matched with backstay, the backstay that cylindrical die puts matches with the bar-shaped trough on wire drawing machine die holder can prevent rotation of the present utility model in drawing process, there will not be the conductor monofilament distortion drawn out, improve the qualification rate of product, ensure that the quality of product.The utility model need not draw by special special drawing machine, and structure is simple, easy for installation, greatly can reduce the production profile conductor monofilament cost of enterprise.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the main cross-sectional schematic of a kind of special-shaped wire-drawing die tool according to the technical solution of the utility model proposition.
Fig. 2 is the schematic side view of Fig. 1.
Fig. 3 is the main cross-sectional schematic of the another kind of special-shaped wire-drawing die tool according to the technical solution of the utility model proposition.
Fig. 4 is the schematic side view of Fig. 3.
Fig. 5 is view when special-shaped wire-drawing die tool of the present utility model is contained on wire drawing machine die holder.
Detailed description of the invention
See Fig. 1, Fig. 2, special-shaped wire-drawing die tool of the present utility model, comprise cylindricality die sleeve 1, there is in cylindricality die sleeve 1 core rod 2, have wire drawing passage 3 in core rod 2, one end of wire drawing passage 3 has incoming line 4, and the other end has line outlet 5, the cross section of described wire drawing passage 3 is in watt shape, and its bore diminishes from incoming line 4 gradually to line outlet 5.
Again see Fig. 3, Fig. 4, described cylindricality die sleeve 1 can be fixed with the backstay 6 overlapping axes normal with this cylindrical die.
See Fig. 5, Fig. 5 shows state when special-shaped wire-drawing die tool of the present utility model is contained on wire drawing machine die holder, after the cylindricality die sleeve 1 of the utility model special-shaped wire-drawing die tool is fixedly mounted with the backstay 6 overlapping axes normal with this cylindrical die, wire drawing machine die holder needs offer the bar-shaped trough matched with backstay 6, now with the conductor thread core of common wire drawing machine by special-shaped wire-drawing die tool processing cable of the present utility model time, the utility model can not produce rotation, can ensure the quality of the special-shaped conductor core produced.
