Description

Preform descaling bath

Technical field

The utility model is related to a kind of optical fiber production device, and in particular to a kind of preform descaling bath.

Background technology

In fiber manufacturing industry prefabricated rods process, preform workpiece need to be removed certain thick by mix acid liquor The impure surface of degree（Including inner surface）, referred to as sour etching technique.In this procedure, in the optical fiber of long cylinder or cylindrical shape Prefabricated rods workpiece is lain in descaling bath with prone position.To improve production efficiency, generally more than one piece preform workpiece is concentrated on Acid corrosion processing is carried out together.Because the length of preform workpiece is variant, the prefabricated rods workpiece of different rod length can not be simultaneously Acid corrosion process is completed into descaling bath.Therefore, we simultaneously can enter the prefabricated rods workpiece of different rod length in the urgent need to a kind of The descaling bath of row pickling.

Utility model content

The purpose of this utility model is to provide the rest stand energy edge in a kind of preform descaling bath, the descaling bath Preform workpiece is moved axially, so that the preform workpiece of different rod length carries out pickling.

The technical scheme that the utility model is used is：

A kind of preform descaling bath, including descaling bath body and the intrinsic some rest stands of descaling bath are placed in, First groove of the rest stand top provided with multiple placement preform workpiece；On the one or both sides of descaling bath body, edge Preform workpiece axial direction is provided with guide rail；It is recessed that the one or both sides of the rest stand are provided with second be adapted with guide rail Groove, rest stand is realized by the second groove, guide rail and slided in descaling bath body.

First groove is V-arrangement or arc, in order to make and place preform workpiece.

The both sides of first groove are provided with cone, and the bottom of cone is connected with the cell wall of the first groove, the top of cone Contacted with preform workpiece point, in order to which preform workpiece can realize thorough pickling, do not stay dead angle.

Second groove is dovetail groove, and guide rail is the dovetail guide matched with dovetail groove, in order to make and install.

The dovetail guide of descaling bath body side has multiple, and rest stand side is provided with the multiple swallows corresponding with dovetail guide Tail groove（One rest stand of multiple dovetail guide correspondences）, so that structure is more stable.

The dovetail guide of descaling bath body one or both sides has multiple, and the dovetail of each descaling bath body one or both sides Guide rail one rest stand of correspondence, so that multilayer fibers prefabricated rods workpiece can carry out pickling simultaneously.

Rest stand bottom is provided with the 3rd groove, in order to the circulation and the placement of preform workpiece of pickle.

Breach, installing and taking out in order to rest stand are provided with the two ends or middle part of guide rail.

The beneficial effects of the utility model are：

By the setting of guide rail and the second groove, rest stand is set to be slided in descaling bath body, therefore can be applicable simultaneously In the pickling of the preform workpiece of different length；

Rest stand with dovetail groove is discharged in descaling bath body without consistency from top to bottom, disclosure satisfy that random length predispersed fiber Rod workpiece processed concentrates the requirement for placing and completing acid corrosion process in descaling bath, improves production efficiency；

It is simple in construction, it is easy to use, it is easy to utilize.

Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain this Utility model, is not used to limit the utility model.

Referring to Fig. 1-Fig. 4, a kind of preform descaling bath, including descaling bath body 1 and it is placed in descaling bath body 1 Multiple rest stands 10, V-shaped first grooves 3 of the top of rest stand 10 provided with multiple placement preform workpiece are putting The bottom for putting frame is provided with multiple the 3rd grooves 5 in circular arc, in order to place preform workpiece and be easy to pickle Circulation；On the both sides of descaling bath body 1,2 dovetail guides 2 are respectively equipped with along preform workpiece axial direction；Putting The both sides for putting frame 10 are provided with the dovetail groove 4 being adapted with dovetail guide 2, and rest stand 10 passes through dovetail groove 4, dovetail guide 2 Slide in the descaling bath body 1, so as to this preform with descaling bath can be applied to simultaneously full-length preform 7, Lengthen the pickling of the different rod length such as preform 8, short fiber prefabricated rods 9.Cone 11, cone are provided with the both sides of the first groove 3 The bottom of body 11 is connected with the cell wall of the first groove 3, and top and the preform workpiece of cone 11 carry out point and contacted, in order to Preform workpiece can realize thorough pickling, not stay dead angle, improve pickling rate.

In use, setting rest stand at the two ends of preform workpiece, make to keep certain between preform workpiece Gap so that the acid etching solution mobility required for ensureing technique, avoids mutually colliding between preform workpiece.

In the utility model, the groove of the first groove 3 or other shapes, such as arc or rectangle, as long as can be convenient Place preform workpiece just.The guide rail of dovetail guide 2 or other shapes, as long as conveniently making and being easy to groove to slide Move just.The groove of dovetail groove 4 or other shapes, it is convenient to make and slide just as long as matching with rail shapes. The shape of 3rd groove 5 is alternatively other shapes, as long as facilitating the placement of preform workpiece and being easy to the circulation of pickle Just.

In the utility model, installing and taking out for the ease of rest stand 10 can be set at the two ends or middle part of dovetail guide 2 Breach 6.

It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted, And all these modifications and variations should all belong to the protection domain of the utility model appended claims.
