Description
Technical field
Fall wimble device and control method the present invention relates to a kind of preform sleeve pipe, and in particular to a kind of RIC rods set
Pipe falls wimble device and control method.
Background technology
Field is manufactured in preform, there are a variety of preform modes of production including RIC rods.In order to improve
The production length of single prefabricated rods, and then manufacture efficiency and reduction fiber manufacturing cost are improved, preform technology is through excessive
Year is explored with developing, and have finally chosen the process route of two-step method, i.e., plug and outsourcing is separately manufactured, then in production optical fiber
When be combined, so as to ensure that optical fiber quality and production efficiency.In recent years, directly by plug insertion and plug phase
The preform of composition is referred to as RIC rods in the unstretched large scale sleeve pipe matched somebody with somebody.In RIC rod production process, high-purity
Large scale quartz socket tube is not needing stretching, and such production technology not only reduces stretching process, improves yield rate, moreover it is possible to
Thus the preform of major diameter is prepared, efficient attenuation is substantially increased, so as to advantageously reduce fiber manufacturing cost.
At present, in sleeve pipe preparation process, one end of the sleeve pipe deposited need to be polished to form certain taper,
Because mechanically operated congenital limitation leads to not conehead being polished into normal production taper, so that being bored after sleeve pipe polishing
Head shapes and wall thickness degree can not meet the assembling of later stage plug and produce；Other casing inner diameter is more than diameter of mandrel, plug without
Method is placed in set pipe cone section, and the conehead of script mechanical grinding is excessive, and later stage sealing difficulty is larger；At the same time, casing hanger
Due to air pressure higher inside fiber drawing furnace during rod, often dag is easily polluting under the influence of draught head in sleeve pipe in stove
Inside pipe casing.It would therefore be highly desirable to which that develops a kind of RIC rods sleeve pipe falls wimble device, RIC rods sleeve pipe is inserted in fiber drawing furnace, to itself plus
Thermal energy melts can reduce the entrance RIC rod sleeve pipes of dag to a certain extent into normal conehead, and reduction later stage sleeve pipe is clear
Wash difficulty.
The content of the invention
The purpose of the present invention is achieved through the following technical solutions, and a kind of RIC rods sleeve pipe falls wimble device, including tail pipe
Sealing device and feeder, the stern tube sealing include a metal cap matched with tail pipe, and one equal with three
The chassis of the metal holder of even distribution and a rubber ring matched with tail pipe Top section size, in the groove that tail pipe is opened
The embedded chassis with metal holder, clamping metal cap by the metal holder on chassis will with the rubber ring on tail pipe Top section
The air supply channel communicated with the external world is provided with Stern tube seal, the metal cap, and air supply channel is communicated with tail pipe, the supply dress
Put including external world's access gas and gas mass flow controller, the feeder passes through the supply in tracheae and metal cap
Passage is communicated, and the gas mass flow size that control is passed through.
Further, the metal holder includes two clamping parts and fastening part (preferably nut), wherein, upper end clamping part
With moveable free end, lower end clamping part, which has, is fixedly connected end and and upper end with " L " type of tail pipe groove match
The end of thread of clamping part connection, by fastening part fasten upper end clamping part cause rubber ring between metal cap and tail pipe fasten and then
By Stern tube seal.
Further, after the Stern tube seal by the sole with three equally distributed metal holders on fiber drawing furnace
The hanging rod platform of side.
Further, access gas is argon gas outside the feeder.
Further aim of the present invention is achieved through the following technical solutions, and a kind of cone that falls of utilization RIC rod sleeve pipes is filled
That puts control sleeve pipe falls cone method, comprises the following steps：
(1) Stern tube seal：Will be upright to the tail pipe and sleeve pipe that connect, using stern tube sealing first in tail pipe Top section
Sizeable rubber ring is put, the internal metal cap for being provided with air supply channel is then covered, it is then embedded in tail pipe bottom groove
Enter the chassis with metal holder, then will with the rubber ring on tail pipe Top section by the metal holder clamping metal cap on chassis
Stern tube seal；
(2) gas mass flow is controlled：Air supply channel in metal cap is carried into gas mass flow by tracheae access
The feeder of controller, the gas for controlling to be passed through in tail pipe by gas mass flow controller according to sleeve pipe and fiber drawing furnace type
Weight uninterrupted；
(3 fall cone shaping：Tail pipe frame after sealing is made above fiber drawing furnace on hanging rod platform, injecting to heat up after fiber drawing furnace
Sleeve pipe conehead is melted and molded.
Handled the advantage of the invention is that falling cone by the sleeve pipe to mechanical grinding, result in normal production cone
Head, and the bore reduced can simplify later stage envelope cone operation and plug assembly difficulty, and lead to inside pipe casing certain gas
Body, can reduce the dag into fiber drawing furnace, can change cone by adjusting the gas size being passed through in sleeve pipe in addition
The thickness and shape of head wall obtain preferable conehead, reduction later stage sleeve pipe cleaning difficulty, so as to simplify rod flow processed, drop
Low probability of doing over again, improves production efficiency.
