Description
Technical field
The present invention relates to a kind of production method of tandem wire.
Background technology
Along with Communication in China technology development, the demand of market to various data cable also increases year by year, wherein wire drawing insulator string alignment as a kind of high speed data lines more user widely use.The production technology of this tandem wire mainly comprises: copper bar is added hot wire drawing, and by the copper core after insulation extrusion to wire drawing.But in the existing tandem wire mode of production, each step operation is discontinuous, and production efficiency is lower, urgently improves.
Summary of the invention
For prior art Problems existing, the object of the invention is to the production method proposing a kind of tandem wire, by enforcement of the present invention, improve production efficiency.
For reaching this object, the present invention by the following technical solutions:
A production method for tandem wire, is applied in the equipment comprising the head rolling machine, wire drawing die, extruder, tank and the take-up reel that connect successively, said method comprising the steps of:
By copper cash through determine core, guiding module, die sleeve through tank wind draught line, through dry wheel, takeup tension take turns, enter take-up reel;
When machine to be extruded reaches preset temperature, blow-off valve is opened, the aging material in start discharge machine neck;
Emptying in material aging in extruder, Insulation Material plastifying state reaches plasticizing when requiring, opens inlet valve and adjusts extruder speed, making heart yearn external diameter reach technological requirement; After reaching line speed, normally run after setting metering length.
Preferably, also comprise before:
Wear wire drawing die;
Coiling; And
Extruder adjusts.
Preferably, enter take-up reel described in specifically to comprise: take-up brake is loosened, take-up reel is wound around 6-7 circle, after opening brake, start described take-up reel.
Preferably, also comprise afterwards: certainly move dish.
In the present invention, improve rate of finished products, improve production efficiency.
Invention accompanying drawing
Fig. 1 is the flow chart of the production method of a kind of tandem wire that the embodiment of the present invention 1 provides.
Embodiment
The embodiment of the present invention 1 provides a kind of production method of tandem wire, and be applied in the equipment comprising the head rolling machine, wire drawing die, extruder, tank and the take-up reel that connect successively, described method comprises the following steps as shown in Figure 1:
Step 101, wears wire drawing die: with head rolling machine, oxygen-free copper bar is rolled spy's head, put on wire drawing die from big to small successively, there is the hole of individual definite shape at the center of wire drawing die, circle, side, anise or other special shape, metal is hauled to diminish through size during nib, and even shape all changes.Because the size dimension of wheel hub is the same, according to the girth of wheel hub size, rationally by the length of wire drawing line between row's mould, what ensure when coiling is easy to operate, thus shortens and wear the mould time.
Step 102, opens wire drawing room protective door, crawl foot switch, and there are 17 road die holders wire drawing indoor, must vacate when using 15 road wire drawing die from 2 roads above.On each road wire drawing wheel hub, wire drawing die is put into die holder around 2 circles successively simultaneously.After copper cash is drawn from last one mould, check that emulsion all must arrive wire drawing die inlet wire die orifice position, close wire drawing room door, open emulsion water pump hand switch.Then, open annealing chamber's door, copper cash is taken turns around to constant speed, crawl foot switch, and draw annealing chamber by guide wheel, conductive casters, straining pulley, close annealing chamber's door, ensure that annealing chamber's door is in good sealing state.
Step 103, adjustment extruder.Observe extruder temperature and whether meet extruder running requirements (extruder can be started separately according to design temperature in ± 10 DEG C of situations), guiding module, die sleeve are carried out isothermal assembling after cleaning out, in core rod installation process, necessary discharge once, the silk brush remained in die gap in cleaning mold process is lost junk get rid of, the sizing material sticked on guiding module and vitta shunt is cleared up with air pressure gun, die sleeve is installed, die sleeve outwards must exit 1 after installing and 1/3rd circles, guarantees smooth discharging.
Step 104, after die assembly is good by copper cash through determine core, guiding module, die sleeve through U-shaped tank wind draught line, through dry wheel, air blowing, air-breathing, direct current spark instrument, takeup tension take turns, enter take-up reel.Take-up brake is loosened, dish tool is wound around 6-7 circle, presses this take-up switch after opening brake, when machine temperature to be extruded reaches requirement, blow-off valve is opened, the aging material in start discharge machine neck.
Step 105, opens the switch of the air valve at each position, water valve and caliper, Spark plug optical fiber sensor instrument (normal voltage 2.5KV), sets observing and controlling parameter and observing and controlling state by technological requirement; Laying tension generally sets 13 ± 1kg, and takeup tension generally sets 16 ± 1kg.
Step 106, waits aging material in extruder emptying, and Insulation Material plastifying state reaches plasticizing when requiring, opens inlet valve and adjusts extruder speed preset knob, making heart yearn external diameter reach technological requirement, finally adjusting always given, reach line speed and technique.
Step 107, setting metering length, take-up reel is changed in automatic control, (start line is because of in Mass adjust-ment, data performance can not be guaranteed, on-the-spotly must report process) first-class blank panel, prepare to change dish next time and use (the dish tool of tandem wire use is 500 types), last meter counter enters normal operation after arranging auto zero.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
