Description
Technical field
A kind of cutting tool is the utility model is related to, especially a kind of cable metal sheath cutting tool.
Background technology
At present, 110kV and above electrical cable aluminium sheath cut no specific purpose tool, are cut always using saw bow
Cut, because cable aluminum metal jacket surface is in wavy, during with saw bow ring cutting, stripping mouth is difficult straight, is all often
It is skewed, the positioning of next step annex installation dimension can be influenceed, operating personnel's operation difficulty is larger in addition, is to compare consumption first
Muscle power, secondly also compare and lose time, especially under special circumstances（Such as some fault in-situs, in cable bridge case etc.）Narrow and small
The difficulty that operation is carried out in space can be very huge；Saw bow is during metal aluminium sheath is cut, it is easy to damages cable body
Semi-conductive layer, insulating barrier etc., once occurring, if do not gone through, such case is very likely ignored, and consequence will very
Seriously.If it can search in time, then also to scrap damage section cable, the risk that cost waste be present；Saw bow is in cutting gold
During belonging to aluminium sheath, the semi-conductive layer that substantial amounts of metal fragment is attached to memory layers and cable body can be also produced, especially
The metal fragment being attached on the semi-conductive layer of cable body, this part metals chip can change the electrical resistance of cable semi-conductive layer
Can, after cable longtime running, comparatively electrical breakdown easily occurs for these positions.
The content of the invention

Hole, it is arranged on after other end bending downwards in mounting seat；Slot is provided with mounting seat；Folder is promoted to be inserted on slot, and
Insertion end is provided with screwed hole, and jaw is provided with outer end；Circular shear blade is rotatably mounted on jaw；One end of augering screw is passed through
Wear mounting seat and stretch into slot and screw on screwed hole, the other end is provided with handlebar stem；Set on augering screw and in slot
Limited location flange collar；Positioning hole is interval with one end of moving knife bar, the other end is bent downwards, and is provided with and circle on bending end
The relative roller of shape blade；In the jack of one end insertion stationary knife bar one end of moving knife bar, and after passing through Socket walls by alignment pin
It is inserted on positioning hole.
Arch knife rest is formed using stationary knife bar and moving knife bar so that circular shear blade and roller are clamped in cable both sides relatively,
In rotary course to circuit sheath carry out ring cutting, not only efficiency high, and otch is straight, will not to cable semi-conductive layer and absolutely
Edge layer causes to damage；The pressure of circular shear blade is conveniently adjusted using augering screw, realizes the fine setting of depth of cut；Using positioning hole
Cooperation with alignment pin can realize the regulation of cutting bore, be easy to the cable sheath of different model to cut and use.
As further limits scheme of the present utility model, projection is provided with jack inwall；Groove is provided with moving knife bar；
Projection is in groove when moving knife bar is inserted into jack.Stationary knife bar and moving knife bar are able to ensure that using the cooperation of projection and groove
Docking stability.
As further limits scheme of the present utility model, two diameters and roller are additionally provided with the bending end of moving knife bar
Identical balance rollers；Two balance rollers are coaxially disposed with roller, and roller is between two balance rollers.Using two
Balance rollers are used for stablizing cutter and metal sheath, it is ensured that otch is straight, and frictional force when reducing rotation.
As further limits scheme of the present utility model, it is provided with the end that stationary knife bar is bent downwards and is connected with jack
The logical groove of the notch；One end of moving knife bar insertion is stretched out by the groove of the notch.Using the groove of the notch end can be easy to stretch out and realize long length
Regulation.
The beneficial effects of the utility model are：Arch knife rest is formed using stationary knife bar and moving knife bar so that circular shear blade
It is relative with roller to be clamped in cable both sides, ring cutting, not only efficiency high, and otch is put down are carried out to circuit sheath in rotary course
Directly, cable semi-conductive layer and insulating barrier will not be caused to damage；The pressure of circular shear blade is conveniently adjusted using augering screw, is realized
The fine setting of depth of cut；The regulation of cutting bore can be realized using the cooperation of positioning hole and alignment pin, is easy to different model
Cable sheath cutting uses.
