A die core hole 21 communicated with the feeding channel 3 is formed in the center of the die core 2. By laying out structures and the positions of the die core and the die sleeve of the extrusion die reasonably, a one-step machining forming method is adopted for machining, compared with the prior art, the insulation thickness can meet a designing requirement, products can fully meet the technical requirements of ultrathin-wall cables, product quality and production efficiency of the ultrathin-wall cables are improved, and the die has the advantages of being advanced in design and convenient to operate and has good economical and social benefit.

Description

Exempt from tuningout ultra-thin-wall cable extrusion mould and processing method thereof
Technical field
The present invention relates to the cable extrusion mould of cable manufacture field, particularly a kind of tuningout ultra-thin-wall cable extrusion mould and processing method thereof exempted from.
Background technology
The ultra-thin-wall cable is an emerging product of cable industry, because it has the characteristics such as size is little, quality is light, current-carrying capacity is large, anti-flammability is high, easy mounting and installation, economize on resources and equip the space, improve the operating efficiency of equipment, so extensively should be in high-end equipments such as bullet train, urban rail transit vehicles, aerospace flight vehicles.
The main difficulty of production ultra-thin-wall cable is extruding of cable insulation jacket.Because the main feature of ultra-thin-wall cable is exactly that the cable wall is ultra-thin, is generally 0.18mm, this thickness is extruded the limit near cable, so the phenomenon that core shift often occurs even wear wall in the production process.
Summary of the invention
One of purpose of the present invention is the above-mentioned deficiency that overcomes prior art, and provide a kind of product quality and production efficiency high, easy to operate exempt from tuningout ultra-thin-wall cable extrusion mould.
The technical scheme that realizes above-mentioned purpose of the present invention is: a kind of tuningout ultra-thin-wall cable extrusion mould of exempting from, comprise core rod and die sleeve, die sleeve is installed in the endoporus of core rod and welds together with core rod and becomes as a whole, be provided with the sizing material passage between core rod and the die sleeve, have some charging holes, core rod center with sizing material passage UNICOM that core rod hole and wire guide with sizing material passage UNICOM are arranged on the core rod, there is the die sleeve hole with sizing material passage UNICOM at the die sleeve center.
The further technical scheme of the present invention is: charging hole is distributed on the taper seat take the core rod center line as axis.
Two of purpose of the present invention is the above-mentioned deficiencies that overcome prior art, and a kind of product quality and high, the easy to operate processing method of exempting from tuningout ultra-thin-wall cable extrusion mould of production efficiency are provided.
Technical scheme of the present invention is: a kind of processing method of exempting from tuningout ultra-thin-wall cable extrusion mould comprises the steps:
The first step: the endoporus that is used for the insert die sleeve in core rod processing;
Second step: processing die sleeve;
The 3rd step: be installed in die sleeve in the core rod endoporus and reserve the sizing material passage,, polishing tight to its weldering at outer surface;
The 4th step: from a side of die sleeve, process core rod hole with sizing material passage UNICOM at the core rod center by die sleeve; Again centered by the core rod hole, processing mould trepanning on die sleeve;
The 5th step: at profile and the wire guide of core rod tail end processing core rod;
The 6th step: process charging hole at the taper seat take the core rod center line as axis.
The present invention is by carrying out rational deployment to the die sleeve of extrusion die and structure and the position of core rod, adopt the processing of time processing forming method, can directly extrude after being installed to extruder, not need manual adjustment core shift degree, compared with prior art, ensure that insulation thickness meets designing requirement, product can satisfy the specification requirement of ultra-thin-wall cable fully, improves product quality and the production efficiency of ultra-thin-wall cable, has advanced design, easy to operate characteristics have good economic benefit and social benefit.
Below in conjunction with figure and the specific embodiment detailed structure of the present invention is further described.
