Abstract
The utility model discloses a device for a manufacturing large size optical fiber preformed rod, comprising a mandrill clamp, a quartz sleeve, an extension furnace and an extended rear handle clamp arranged successively. The mandrill rear handle is clamped in the mandrill clamp. A preformed rod extended rear handle is clamp in the extended rear handle clamp and the mandrill is clamped between the mandrill rear handle and the preformed rod extended rear handle. The mandrill is sleeved in the quartz sleeve. One end of the quartz sleeve is disposed in the extension furnace and the quartz sleeve is connected with a sleeve rear handle which is connected with a sealing device. An exhaust hood is arranged outside the sealing device and a sleeve clamp is clamped on the sleeve rear handle. The device is able to reduce the requirements of geometric accuracy and evenness of large size mandrill so that the large size mandrill manufactured by vacuum arc deposition process is suitable for a method for manufacturing a large size quartz optical fiber preformed rod.

Background technology
But the drawing optical fiber length of making large-sized prefabricated quartz fiber rod, the single prefabricated rods of increase is the effective way that improves optical fiber production efficient, reduces production costs.The existing method of making large-scale optical fiber prefabricating stick adopts axial vapor deposition process (VAD technology) to make the large size rock quartz core rod usually; Again plug is inserted and form molectron in the quartz socket tube; Then with the molectron thermoplastic and melt into large-sized prefabricated rods, the large size plug that adopts VAD technology to make then, geometric accuracy is wayward; Its Bao Xin is bigger than fluctuation, has limited the size of making prefabricated rods.
The utility model content
For overcoming the deficiency that exists in the prior art; The purpose of the utility model is to provide a kind of equipment that is used to make large-scale optical fiber prefabricating stick; This equipment can reduce the geometric accuracy of large size plug and inhomogeneity requirement, and the large size plug that axial vapor deposition process (VAD technology) is made can be applicable to the method that large size rock quartz optical fibre prefabricated bar is made.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is realized through following technical scheme:
A kind of equipment that is used to make large-scale optical fiber prefabricating stick comprises plug anchor clamps, quartz socket tube, extension stove and the stretching caudal peduncle anchor clamps arranged successively, and said plug anchor clamps folder is established the plug caudal peduncle; Said stretching caudal peduncle anchor clamps folder is established the preform bar stretching caudal peduncle; The said folder of establishing between plug caudal peduncle and the said preform bar stretching caudal peduncle is established plug, and said plug is inserted in the said quartz socket tube, and said quartz socket tube one end places in the said extension stove; Said quartz socket tube is connected with a sleeve pipe caudal peduncle; Said sleeve pipe caudal peduncle connects a tightness system, and said tightness system is outside equipped with exhaust hood, and is folded with never-slip on the said sleeve pipe caudal peduncle.
Further, said exhaust hood comprises a metal case, offers a nitrogen inlet on the said metal case end cap, offers a venting port on the cover wall.
Further, said tightness system comprises a quartzy pressure ring, and said quartzy pressure ring one end is through said sleeve pipe caudal peduncle sealing, and the other end is provided with graphite envelope ring, and offers venting hole on the sidewall of said quartzy pressure ring.
Compared with prior art, the utlity model has following beneficial effect:
The utility model can effectively overcome the problem that large size prefabricated rod is made in the not good restriction that causes of axial homogeneity that VAD process deposits large size plug exists.Plug is installed separately on different anchor clamps with quartz socket tube, can adopt the way control plug of plug and the asynchronous extension of quartz socket tube to advance to tie up speed, solves Bao Xin than the big plug that fluctuates to making the restricted problem of large size prefabricated rod.The utility model is employed in sleeve pipe caudal peduncle top and tightness system is set plug and quartz socket tube gap are vacuumized; Preventing that effectively plug and quartz socket tube from receiving secondary pollution problem in the process that rotation is extended, is a kind of high-level efficiency, the low-cost method of making large-scale optical fiber prefabricating stick.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technique means of understanding the utility model, and can implement according to the content of specification sheets, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
