Description
Technical field
This utility model belongs to optical cable manufacture field, is related to cable jacket extrusion die, especially a kind of control ADSS light
Cable sheath and the mould of cable core tightness.
Background technology
ADSS optical cable is All Dielectric self-support, be one kind be all made up of dielectric material, itself comprise necessary
Support system, the non-metallic optical fiber cables that can directly hang on electric force pole tower, are mainly used in the communication lines of aerial high voltage power transmission system
Line is it can also be used to the built on stilts communication line laying under environment such as the multiple area of thunder and lightning, large span.
ADSS optical cable adopts different sheaths in different electric power routes, and modal ADSS sheath has two kinds:PE sheath
With AT sheath.Rope roundness good, knot size less than normal in the case of, compare conjunction so that plastic sheath is extruded using plsitive mold
Suitable, plsitive mold can make the sheath Rotating fields after molding closely knit, can fill up fluidised form plastics in the gap of hoist cable line periphery, make
Its rugged construction is stablized and surface rounding.When optical cable core outside diameter tolerance is big, when roundness is bad, extruded using tubular molding tool
Plastic sheath can overcome the uneven shortcoming of conductor assembly outer diameter, because tubular molding tool is to realize cladding through stretching after tubular moulding
, therefore mould highly versatile.
But tubular molding tool there is a problem of in use certain, such as squeeze pipe stretch out core rod length wayward,
Lead to ADSS cable jacket wayward with cable core tightness.The micro-judgment of operator is typically relied in existing production,
There is larger interference from human factor, need to take a substantial amount of time, do not only result in that product disqualification rate is higher, standard is poor；
Also fragile mould, blocks hole slot, increases maintenance maintenance cost, waste of resource, impact production efficiency and product quality.
Utility model content
In place of the purpose of this utility model is to overcome the deficiencies in the prior art, provide one kind using simple, simple operation,
Can be with the mould of effective control ADSS cable jacket and cable core tightness.
This utility model solves above-mentioned technical problem and takes technical scheme below to realize：
A kind of control ADSS cable jacket and the mould of cable core tightness, including die sleeve and core rod, described die sleeve and mould
Core is coaxially disposed, and this core rod coaxial spaced is inserted in described die sleeve, is provided with plastic cement extrusion logical between this die sleeve and core rod
Road, is coaxially fitted with a cavity threaded rod in core rod, and this cavity threaded rod passes through external screw thread and core rod inwall outside the body of rod
On female thread connect, the front port of core rod is stretched out, on the front end face of described cavity threaded rod in the front end of described cavity threaded rod
Offer the hole slot passing through for optical cable core.
And, described core rod is cavity taper structure, is made up of Cable entry, conical cavity and cable exit, described light
Cable entrance connects the major diameter mouth of described conical cavity, and the minor diameter mouth of this conical cavity connects described cable exit, described cavity
The external screw thread that threaded rod passes through outside the body of rod is threadeded with the female thread of described taper cavity wall.
And, the part that die core front end mouth is stretched out in the front end of described cavity threaded rod is shiny surface, does not have external screw thread to arrange,
The rear end of this cavity threaded rod is coaxially installed with dismountable regulation handle.
And, this cable exit diameter is less than described Cable entry diameter.
Advantage of the present utility model and having the beneficial effect that：
1st, this utility model is coaxially fitted with a cavity threaded rod in taper intracavity, and this cavity threaded rod passes through outside the body of rod
External screw thread be connected with the female thread on core rod inwall, can by screw this cavity threaded rod adjust cavity threaded rod front end
Stretch out the length of die core front end mouth, can be with effective control ADSS cable jacket and cable core tightness, it is to avoid artificial micro-judgment
The error causing is big, and degree of accuracy is low, the problem of impact product quality.
The 2nd, the hole slot passing through for optical cable core is offered on the front end face of cavity threaded rod, optical cable core can lead to
Cross；The movable dismounting of cavity threaded rod, can make a plurality of cavity threaded rod according to the diameter of different size cable core,
The front end of cavity threaded rod opens up the hole slot of different-diameter, need not repeat to make die sleeve and the core rod of sheath extrusion die, save
Material, it is to avoid the generation of eccentric phenomena, convenience and high-efficiency.In the rear end of cavity threaded rod, regulation handle is detachably installed, convenient
Operation.
3rd, this utility model structure is simple, easily manufactured, and operation is simple, with low cost, and innovative point is in core rod same
Axle thread is fitted with a cavity threaded rod, can adjust, according to needs of production, the length that this cavity threaded rod stretches out core rod
Degree, for controlling ADSS cable jacket and cable core tightness, and is applied to the optical cable of different size and uses, and economical and efficient is fitted
For vigorously promoting the use.
Brief description
Fig. 1 is part sectioned view of the present utility model (vertical view).
Specific embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, no
It is determinate it is impossible to protection domain of the present utility model is limited with this.
A kind of control ADSS cable jacket and the mould of cable core tightness, as shown in figure 1, including die sleeve 1 and core rod 3,
Described die sleeve and core rod are coaxially disposed, and this core rod coaxial spaced is inserted in described die sleeve, arrange between this die sleeve and core rod
There is plastic cement extrusion passage 2.Described core rod is cavity taper structure, is made up of Cable entry, conical cavity 5 and cable exit, institute
State the major diameter mouth that Cable entry connects described conical cavity, the minor diameter mouth of this conical cavity connects described cable exit, this optical cable
