Specific implementation mode
The muffle tube dismantling device is made of casing 1, pull rod 2, resetting spring 3 and clamping jaw 4：Casing 1 is in step type；Casing
Activity is equipped with pull rod 2 in 1；One end of pull rod 2 extends to 1 outer end of casing；2 end of pull rod for extending to 1 outer end of casing is fixed with
Limit screw cap 5；Activity is equipped with resetting spring 3 and spacing shim 6 successively on the pull rod 2 of 5 side of limit screw cap；Spacing shim 6 with
The end of casing 1 contradicts connection（Referring to Figure of description 1）.
The other end of pull rod 2 extends to 1 outer end of casing；It is convex that the end for the pull rod 2 for extending to 1 outer end of casing is fixed with expansion
Edge 7；7 side activity of flange is expanded equipped with driving gasket 8；It is fixedly mounted on the pull rod 2 of 8 side of driving gasket and contradicts flange 9；It contradicts convex
Edge 9 is located inside 1 butt end of casing.
It by bearing 10 and ships and resell on another market on the periphery of 1 butt end of casing and 11 is uniformly movably installed with multiple clamping jaws 4；Clamping jaw 4 is in
The middle part of " rectangle ", clamping jaw 4 is provided with turn hole 12；Clamping jaw 4 can be by turn hole 12 around 11 rotations of shipping and reselling on another market.
The side side of clamping jaw 4 is in plane；Clamping jaw will be hooked by plane inside muffle tube when work, be set to put down
The purpose in face is：It is led to the problem of when it being prevented to be in other shapes and scratches muffle tube.
4 upper surface of clamping jaw is provided with oblique transition face 13；When work, clamping jaw 4 is inserted into contraction state inside muffle tube；
The purpose that oblique transition face 13 is arranged is：The volume for reducing occupied space when clamping jaw 4 is shunk, prevents it from occurring with muffle tube
" bite " accident.
The lower face of clamping jaw 4 is provided with arc transiting surface 14, and arc transiting surface 14 extends to driving gasket 8 and expansion flange
Between 7.The purpose that arc transiting surface 14 is arranged is：In order to drive gasket 8 and expansion flange 7 and arc transiting surface 14 to slide
Connection prevents driving gasket 8 and expands the problem of flange 7 occurs that clamping jaw 4 is hindered to rotate.
When the muffle tube dismantling device works, pushing drawing rod 2 makes it overcome downlink after the elastic force of resetting spring 3 first；It draws
It is driven during 2 downlink of bar and contradicts flange 9 and driving 8 downlink of gasket；Push each clamping jaw 4 inside during driving 8 downlink of gasket
Rotation；When pull rod 2 is moved to designated position, it is in " contraction " state that each clamping jaw 4, which inwardly turns to extreme position,.
Then by the port of the tools for alignment muffle tube；And the mobile tool makes to be inserted into the clamping jaw 4 of " contraction " state
The inside of muffle tube；Then releasing lever 2, at this time under the action of resetting spring 3,2 uplink of pull rod resets；In this process
In, expansion flange 7 is with 2 uplink of pull rod；Pull rod 2 pushes each clamping jaw 4 to be turned out during moving up；When pull rod 2 is completely multiple
When position, it is in " strutting " state that each clamping jaw 4, which is turned out to extreme position, and the outer diameter of clamping jaw 4 " strutting " is more than Muffle pipe end at this time
The internal diameter of mouth.The tool is then pulled, each clamping jaw 4 hooks muffle tube from inside at this time, and then above carrying casing 1 can be by Muffle
Pipe takes out from fiber drawing furnace.Subsequent pushing drawing rod 2 makes each clamping jaw 4 be in " contraction " state, takes out the dismantling device at this time.
When assembling muffle tube using the dismantling device, above-mentioned action is repeated.
In above process, when above carrying casing 1, each clamping jaw 4 supports the total weight of muffle tube, and each clamping jaw 4 is interior at this time
It holds end to be contradicted with pull rod 2, the problem of " loosening " occurs with muffle tube is rotated down after thus avoiding 4 stress of clamping jaw.
The muffle tube dismantling device, it is simple in structure, easy to use；Clamping jaw enters in contraction state in muffle tube when work
Portion, in softened state by Muffle pipe clamp；It solves and what disassembly process had currently is carried out to muffle tube using tools such as iron hooks
Operating difficulties and easy the problem of smashing furnace interior part, meet people's needs.
