Description
Technical field
This utility model relates to the wire-changing device that a kind of extruder producing power cable uses, and belongs to power cable and produces technical field of auxiliary equipment.
Background technology
Extruder, as thermoplastic plastic process equipment, is widely used in producing sheath and the insulating barrier of cable. In power cable produces, extruder is mainly used in being coated on insulant plain conductor periphery. Head is one of core position of extruder, head generally comprises handpiece body, mould and diverter etc., handpiece body has one to squeeze, for melted insulant, the inner chamber runner giving as security circulation, mould includes core rod, core rod and die holder, core rod and core rod mainly guide plain conductor and move, being made the insulant melted closely be coated on plain conductor by core rod and diverter, cable is made in extruded and traction stretching.
Demand along with market, a lot of according to customer requirement, it is generally the specific indent formula that quantity is few, specification is many to produce, the head core rod of different-diameter need to be changed at the different cable of production, and while changing core rod, also must change core rod and the die holder of matched use, increase the complexity of mould processing, increase production cost. Current cross-head needs when more mold exchange to dismantle most of parts of head to reinstall; disassembly and assembly time is long; plastic insulation and sheath adopt continuously extruded mode to carry out; easily caused by extruder insulant incipient scorch or precrosslink; cause waste of material; affecting product quality, therefore typically require and shut down more mold exchange, this just have impact on manufacturing schedule.
Utility model content
The purpose of this utility model is in that the drawback for prior art; there is provided a kind of and do not shut down wire-changing device for power cable extruder; more mold exchange need not be shut down when producing the cable of different model, changing plain conductor; realize producing continuously; improve production efficiency, reduce production cost.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of do not shut down wire-changing device for power cable extruder, including mounting head, connecting rod, inner sleeve and Nei Zui, described mounting head is arranged on the side of the handpiece body of extruder plain conductor input, mounting head is the cylindrical structure of the flanged dish with plain conductor coaxial line, cylinder center axially penetrates through and arranges centre bore, mounting head arranges the fixing seat of fixed connecting rod away from the outboard end of handpiece body, described connecting rod is coaxially installed in the centre bore of mounting head, the connecting rod being set in described is positioned at the outfan of handpiece body, described interior mouth is coaxially inlaid in inner sleeve, interior mouth includes docking symmetrically and forms two pieces of semicircular cylinder sheets of hollow cylinder.
Above-mentioned not shutting down wire-changing device for power cable extruder, the longitudinal cross-section of described semicircular cylinder sheet stretches out along the outfan of connecting rod and includes the first oblique section that diameter is gradually reduced successively, faces directly and the second oblique section.
Above-mentioned not shutting down wire-changing device for power cable extruder, described fixing seat includes three pieces of fixture blocks of circumference uniform distribution, described fixture block radially offers through hole, installs the fastening bolt for apical grafting fixed connecting rod in described through hole.
The beneficial effects of the utility model are:
This utility model simple in construction, easy to use. When changing the cable that plain conductor produces different model; need not shut down; only connecting rod need to be complied with wire to take off from mounting head; turn on inner sleeve; owing to interior mouth is two pieces of semicircular cylinder sheets, equally possible when center is coated with plain conductor take off, change corresponding plain conductor diameter different model interior mouth after refill and be fitted on cross-head; improve production efficiency, reduce production cost.
Interior mouth is set to the inclined-plane hierarchic structure that diameter is gradually reduced, is beneficial for disassembly and assembly, saves the time of changing the outfit, reduce labor intensity, improve work efficiency. Fixing seat is by the fixture block of three pieces of circumference uniform distributions and fastening bolt apical grafting fixed connecting rod, easy accessibility, it is ensured that the axiality of connecting rod and plain conductor.
