Principle of the present utility model is such: pressure is that 0.7-0.76MPa compressed air or compressed nitrogen (hereinafter summary is Compressed Gas) are sent into pressure regulator valve 1 by air inlet pipe 11, pressure regulator valve 1 has pressure adjustment knob, outlet pressure is adjusted to 0.5-0.6MPa, owing to thering is the impurity such as oil, moisture content in Compressed Gas, therefore, if it contacts with fiber optic protection blank pipe inwall, can stop up fiber optic protection blank pipe, also can protect fiber optic protection blank pipe and in forming process, occur the phenomenons such as pore, bubble, for this reason, oil and moisture content must be removed, after compressed air first and second air accumulator by mutual serial connection, because air accumulator can not only stores compression gas, minimizing is due to the pressure fluctuation of the discontinuous generation of compressor air-discharging, reduce the frequent starting of compressor, extend the life-span of compressor, realize air feed and by the balance of gas, and can reduce the temperature of Compressed Gas, reduce the load of filter for molten and drier, adopt two air accumulators not only can function as described above, can also make the volume of whole device greatly dwindle, be convenient to transportation and preservation and installation and debugging, therefore two-stage air accumulator has greatly been stablized the pressure of Compressed Gas, and the pressure at the second place, air accumulator gas outlet is 0.5-0.6MPa, Compressed Gas is after voltage stabilizing, enter first and second accurate filter, oil in Compressed Gas and moisture content are removed, obtain purer Compressed Gas, pure Compressed Gas enters precise pressure regulating valve, pass through fine adjustment, the pressure that makes its outlet side is 0.3-0.4MPa, then enter accurate flowmeter, according to size and the speed of production of produced fiber optic protection blank pipe, suitably regulate the flow of Compressed Gas, the pressure that makes the gas outlet of accurate flowmeter is 0.01MPa, gas output is at 12-14L, range of flow regulates between 0-25L/min according to technological requirement.
Be connected to the inlet end 95 of core rod unit 9 in escape pipe 13 connection layouts 2 of gas outlet of accurate flowmeter, adopt the mode of squeezing pipe to produce fiber optic protection blank pipe, core rod 9 inside and the inside of holding path portion 93 be all hollow, the path portion 93 that holds of core rod is arranged in the die sleeve chamber 89 of die sleeve 8, that holds path portion has a perforate 94 foremost, the rear end face of core rod 9 has a through hole, in this through hole, be provided with and lead fine pipe 92, the both ends of leading fine pipe are hollow, and the inside of leading fine pipe is hollow leads fine chamber 921, the inwall of leading fine pipe and core rod is discontiguous and leads the front end of fine pipe and holding of core rod has gap between path portion, while producing fiber optic protection blank pipe, the blank pipe material of melting enters die sleeve chamber 89 from extrusion head along the large direction of arrow, because the relation of pressure flows to the front end in die sleeve chamber, and from hold the die sleeve chamber 89 forming between path portion 93 and die sleeve front end, extrude and form fiber optic protection blank pipe 10, pure from escape pipe 13, the Compressed Gas of pressure and stability of flow enters after inlet end 95, relation due to pressure, compressed air enters and holds path portion 93 and blow out from perforate 94, the compressed air blowing out makes fiber optic protection blank pipe rounding more, tube wall can mutually not bondd when cooling, make the cooling quicker of pipeline, while not adopting the method, when fiber optic protection blank pipe is cooling in tank, outside heat gathers rapidly toward interior, adopt after this method, internal heat is taken away fast, therefore faster crystalline forming.Certainly, compressed air is reflected back from holding the wall body of path portion on the other hand, enter and lead in the fine chamber 921 of leading of fine pin 92 and be discharged to core rod outside, because the inside of core rod has higher temperature, the gas being reflected back has been taken away heat, make the temperature in core rod more stable, the fiber optic protection blank pipe external diameter of producing is more even, wear fine more excellent performance, the geometric identity of blank pipe is better, production repeatedly and test through applicant, after adopting device of the present utility model and mould and method to produce, the product qualified rate of manufacturing fiber optic protection blank pipe has increased substantially 99.3%-99.8% by common 25%-35%, therefore, improved widely efficiency, made that product quality is more stable, reliable, cost is lower.
In Fig. 3, fiber optic protection blank pipe 10 consists of the hole 102 of pipe wall body 101 and hollow.
The former device using in the utility model can be purchased on market.
Therefore, the utlity model has following main beneficial effect: equipment is simple, easily make, easily use, cost is low, and the fiber optic protection blank pipe product qualified rate of production is high, steady quality is reliable, cost is low.
Device of the present utility model is by simple measure, mainly played make the purity of Compressed Gas higher, effect that pressure is more stable.
The utility model can be applied in other conceivable occasion, also belongs to the application's protection domain in the application of other occasion.
The utility model is not limited to above-mentioned preferred forms, should be appreciated that design of the present utility model can be by other various forms enforcement utilizations, and they drop in protection domain of the present utility model equally.
