Abstract
The invention discloses a non-stop extrusion continuous production apparatus. The non-stop extrusion continuous production apparatus comprises a die core base, connectors and a three-layer co-extruder handpiece that perform continuous production. Cable cores are stabilized by the apparatus; when the production apparatus is used for producing crosslinking insulating cable cores of the similar specifications, the production apparatus is not stopped; the cable core replacement can be finished within one minute, so that the time and energy for changing the cable cores of different specifications are saved, the production efficiency is improved and the operation steps are reduced; and therefore, the non-stop extrusion continuous production apparatus is in particularly suitable for the extrusion modes of middle-voltage and high-voltage power cables.
Description
Technical field
The present invention relates to height, medium-pressure power cable production equipment, especially three-layer co-extruded specification of changing does not shut down continuous extruding production equipment.
Background technology
There is thousands of family in current cable enterprise of China, and the dog-eat-dog degree of cable market is well imagined.Present midium voltage cable is widely used in every profession and trade; and the mode of production mainly contains, and catenary suspension type continuous vulcanization is dry, crosslinked two kinds of wet method; each enterprise adopts the three-layer co-extruded production-line technique of catenary suspension type continuous vulcanization dry cross-linking now substantially; when the insulated cable of production plurality of specifications, multiple voltage grade; need to use corresponding mould; even the core of adjacent-specification, also need in extrusion process to shut down mold exchange.Change mold process and need at least 20-30 minute; during this, head keeps heated condition; easily cause shielding material, old glue problem appears in Insulation Material; about discharge at least 50 kilograms even old glue of more than 100 kilogram; each shutdown all can cause at least 40 meters of insulated wire cores in curing tube to scrap in addition, again starts shooting and causes at least 40 meters of cables of taking the lead to scrap.Cause the serious waste of material, the energy, manpower like this.
Summary of the invention
Technical problem to be solved by this invention is not enough for above-mentioned prior art; and provide and do not shut down extrusion continuous production device; can solve during three-layer co-extruded cross-linking insulated wire cores produces, changing specification needs shutdown operation and the problem that causes material, the energy, manpower serious waste.
The object of the present invention is achieved like this: do not shut down extrusion continuous production device; comprise three-layer co-extruding machine head; three-layer co-extruding machine head is made up of head connector (1), device bore (2), and a pair described half module is fixed on head by fixing pin (3) and fixed screw (4).
Described device bore is two halves separable type.
Described head connector, for being threaded, directly coordinates with the core rod seat screw thread hole shape of three-layer co-extruding machine head.
The size of described device bore amplifies about 0.3mm according to the actual size of conductor.
The present invention achieves following technique effect: aborning, in the process of high-tension cable adjacent-specification insulated wire, when needing to change adjacent small dimension, in the conductor tab of two kinds of specification insulated wires by after head, core fixture is carried out involutory fixing.The existence of fixture, can overcome because core rod more greatly and easily shakes the problem causing core shift difficulty tune, instability, can the Eccentricity control of insulation in critical field, and the follow-up outer shielding layer extruded also can not be affected.When namely ensure that insulated wire changes small dimension from large gauge, insulation core shift degree controls, being less than in 15% critical field, not needing again to shut down more mold exchange, thus effectively enhance productivity, and reduces material consumption.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation, and accompanying drawing 2 is sectional views.
In accompanying drawing 1,1-head connector 2-device bore 3-fixing pin 4-fixed screw.
Embodiment
One does not shut down extrusion continuous production device as shown in Figure 1, comprises two halves separable type mould, and two halves separable type mould is made up of head connector (1) and device bore (2); Two halves separable type mould is assembled fixing by fixing pin (3), fixed screw (4).Head connector (1), for being threaded, directly coordinates with three-layer co-extruding machine head screw thread hole shape.Fixture bore (2) is two halves separable type.The size of device bore (2) amplifies about 0.3mm according to the actual size of conductor.
In mould apolegamy, when produce many specification conductors core, select the size of core rod, lining, die sleeve and fixture bore according to maximum specification.In process of production, the large 0.5-0.7mm of boring ratio conductor actual outside diameter in core rod, lining hole size 0.3-0.5mm larger than core rod endoporus, insulating barrier die sleeve caliber size according to insulation thickness and inner shield thickness and twice select.Then cable insulation core outward appearance is better, and insulating exruded tightness is good, and adhesion is strong, and insulation outer shielding layer carries out shunting by head and reaches insulation and insulation external shield co-extrusion object, and insulation external shield outward appearance can reach closely smooth.But when changing a little specification, the core rod deviation of big mould core originally and small dimension is larger, the bores of multiple specification differs about 2-10mm substantially, if directly production easily causes serious core shift, core is shaken very large in crosslinked pipeline, cannot meet the requirement of national standard 15% core shift degree, finally cause cable easily to puncture, partial discharge quantity is large, and cable is had a greatly reduced quality useful life.So the most important thing is that fixed conductor core is not shaken in crosslinked pipeline in the converted kind of many specifications, conductor, through position, core rod middle, avoids the problem that core shift difficulty is adjusted.
When extrusion continuous production device is not shut down in employing, when needs many specifications continuous seepage is changed, when current specifications pay off rack conductor thread core remains about 30 meters, take off conductor thread core from pay off rack and coil small dimension with next and carry out sleeve pipe and crimp, be recovered on draw drum through sanding and polishing after coupling compression joint, when two specification joints during distracted position slow down speed of production on extrusion head; Far and near according to joint distance Handpiece Location, restringing fixture at once, fixture can directly be changed without the need to preheating.Open two halves separable type device, aim at fixing pin, tighten two screw threads, then, one holds fixture, and itself and core rod seat screw thread are connected and fixed by another hand, can produce by next specification after fixing, so just achieve many specifications core and carry out quick-replaceable production.Change small dimension from large gauge only to need 1 minutes to complete to change normal production, device is easy to use without the need to preheating, solves re-use after in the past needing preheating loaded down with trivial details.
