Description
Technical field
It the utility model is related to and prick yarn processing unit (plant) technical field, more particularly to a kind of compound bundle yarn mould.
Background technology
Optical cable is mainly what is be made up of optical fiber and plastic protective sleeve pipe and plastic peel, and optical fiber forms cable according to certain way
Core, it is then outer to be surrounded by sheath, some also cladding outer jackets, cable is formed by certain technique.In the production process of optical cable
There is one of cabling procedure, multifiber beam tube, gasket for packing and center reinforcemen are twisted together, in order to improve stranding production
Efficiency, generally centered on center reinforcemen, optical fiber bundle tubes and gasket for packing are spirally wound together into, optical fiber bundle tubes and filling
Rope with certain toughness and intensity, it is necessary to by pricking yarn process by their banding fixeds, in order to avoid optical fiber bundle tubes and gasket for packing are because of bullet
Property effect return to original linear state.Existing technique is to allow the mode for pricking yarn winding cable core to be tied using bundling machine
Firmly, to ensure to bundle the uniform tension stability for pricking yarn, need to be wrapped in by a mould by yarn is pricked above cable core, existing mould
Have for all-metal part, prick when yarn passes through at a high speed mould that abrasion is big, caloric value is big, mould integral replacing cost is high, and temperature is high easily
Cause to prick yarn deformation retract, influence cable core quality.
Utility model content
Technical problem to be solved in the utility model and the technical assignment proposed are that prior art is improved, there is provided
A kind of compound bundle yarn mould, solves that bundle yarn die wear traditional in current technology is big, caloric value is big, mould integral replacing cost
The problem of high.
To solve above technical problem, the technical solution of the utility model is：
A kind of compound bundle yarn mould, it is characterised in that including external mold and internal model, opened up in described internal model and led to for pricking yarn
The via crossed, the periphery cladding that via circumferencial direction is located in internal model are connected to external mold.Compound bundle yarn described in the utility model
Mould pricks yarn from internal model by the way that pricking yarn and internal model generation friction causes internal model abrasion, hair using external mold and the combining structure of internal model
Heat, internal model conveniently can be only changed when internal model excessive wear, without changing external mold, reduce the quantity of material of replacing, effectively reduce
Mold use replacement cost.
Further, described internal model is stainless steel cylinder, and anti-wear performance is good, and thermal diffusivity is good, avoids high temperature from causing to prick yarn change
Shape is shunk, and ensures cable core quality.
Further, described external mold is bakelite sleeve, and use cost is low, and bakelite does not absorb water, be non-conductive, high temperature resistant, intensity
Height, die size precision, service life length are ensured.
Further, the lock screw hole for being through to internal model outer wall has been opened up on the barrel of described external mold, in lock screw
Screw is installed in hole to hold out against internal model, it is easy to loading and unloading, ensure mould normal use.
Further, the aperture of described via is the narrow transition structure in the wide centre in both ends, increase via and the contact for pricking yarn
Area, avoid via from causing to prick yarn fracture, ensure and prick the continual and steady progress of yarn process.
Further, the seam step coordinated with internal model is provided with the inwall of described external mold, improves property easy for installation, with
Seam step ensures external mold and the fit precision of internal model as positioning datum.
Compared with prior art, the utility model advantage is：
Compound bundle yarn mould structure described in the utility model is simple, low manufacture cost, reduces replacement cost when using,
Installation replacing is convenient and swift, and mould wearability is good, and caloric value is small, avoids high temperature from causing to prick yarn deformation retract, ensures cable core quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Compound bundle yarn mould, conveniently replaced after abrasion disclosed in the utility model embodiment, reduces use cost, heating
Measure it is small, avoid high temperature cause prick yarn deformation retract, ensure cable quality.
As shown in figure 1, one kind is compound to prick yarn mould, including external mold 1 and internal model 2, open up what is passed through for pricking yarn in internal model 2
Via 3, the wide centre in aperture both ends of via 3 is narrow, and the both ends of via 3 are transition structure, and yarn contact with via 3 is pricked in increase
Area, avoid the edge corner angle of via 3 from being blocked yarn is pricked, ensure and prick the continual and steady progress of yarn process, be located at via 3 in internal model 2
The periphery cladding of circumferencial direction is connected to external mold 1, the seam step 5 coordinated with internal model 2 is provided with the inwall of external mold 1, with only
Mouth step is as positioning datum, and in place, internal model 2 is stainless steel cylinder, and external mold 1 is bakelite set for the cooperation of guarantee external mold and internal model
Cylinder, stainless steel anti-wear performance is good, and bakelite high temperature resistant, intensity are high, cost is low, including being caused using the structure of the overcoat external mold 1 of internal model 2
Internal model 2 can be only changed after the serious wear of mould 2, and external mold 1 can be continuing with, and reduce replacement cost, and caloric value is effectively reduced,
Avoid pricking yarn deformation retract, ensure cable quality.
The connected mode of external mold 1 and internal model 2 may be designed as being threaded in the periphery of internal model 2, and internal model 2 and external mold 1 are direct
Threaded connection；Can also be by the way of external mold 1 and internal model 2 be interference fitted；In the present embodiment, opened up on the barrel of external mold 1
The lock screw hole 4 of the outer wall of internal model 2 is through to, screw is assembled on lock screw hole 4 and holds out against internal model 2, simple in construction, handling
It is convenient.
It the above is only preferred embodiment of the present utility model, it is noted that above-mentioned preferred embodiment should not regard
