The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of anti-molten drop blocking impedor, including impedor body, magnetic core, tetrafluoro pillar and location
Set, tetrafluoro protective pipe sleeve is contained on impedor body, and magnetic core ring is loaded on tetrafluoro pillar internal impedance device body
On, positioning sleeve is installed in impedor rear body, described impedor body, by draw rod attachment part,
Asymmetric round tube body, location division, scrape scar bar connecting portion composition, draw rod attachment part, asymmetric
Round tube body, location division, scrape scar bar connecting portion be sequentially connected be made as one, in impedor body
Mandrel is to being shaped with impedor mesopore, and asymmetric round tube body is shaped with water-guiding hole, it is characterised in that:
Described positioning sleeve, is a dumbbell shape positioning sleeve, and end is shaped with tetrafluoro pillar seat, upper rear end thereafter
Being shaped with effluent trough, its both sides, front end are shaped with screw, are all installed with location screw in screw.
And, described location division, screw is corresponding is shaped with detent with location in its both sides, front end.
And, described effluent trough, its inner segment bottom surface is shaped with Caused by Sloping Surfaces.
Advantages of the present invention and having the beneficial effect that
1. the present invention anti-molten drop blocking impedor, its positioning sleeve is dumbbell shape positioning sleeve, and welding can be made raw
The molten drop that during product, solder joint generates has bigger receiving space, can smooth and easy discharge, it is to avoid molten drop blocks up
Plug, it is ensured that cooling current are all smooth, effectively prevent stuck parking, it is ensured that produce smooth and easy.
2. the present invention anti-molten drop blocking impedor, its positioning sleeve upper rear end is shaped with effluent trough, effluent trough
Inner segment bottom surface is shaped with Caused by Sloping Surfaces, both can make to cooling water flow out of smooth and easy, strengthens cooling water recessed to positioning sleeve
The impulsive force in groove portion, makes the molten drop dropping onto positioning sleeve groove thoroughly be washed away in time clean, prevents
Molten drop accumulated plugging, still prevents cooling water and is upwards ejected on weld bond, it is to avoid weld bond cools down too early,
Cause and scrape scar difficulty.
3. the present invention anti-molten drop blocking impedor, its both sides, front end, impedor body location division are shaped with location
Groove, both sides, positioning sleeve front end are provided with location screw, can make positioning sleeve firm position, precisely.
4. the present invention anti-molten drop blocking impedor, scientific structure design is reasonable, have can be prevented effectively from molten
Drip blocking, prevent the abnormal phenomenas such as cooling current the most smooth logical, stuck parking, it is ensured that smooth and easy life
The advantages such as product, are a kind of anti-molten drop blocking impedors with higher innovation.

Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following example simply describe
Property, it not determinate, it is impossible to limit protection scope of the present invention with this.
A kind of anti-molten drop blocking impedor, including impedor body, magnetic core 4, tetrafluoro pillar 2 and fixed
Position set 11, tetrafluoro protective pipe sleeve is contained on impedor body, and magnetic core ring is loaded on tetrafluoro pillar internal impedance device
On body, positioning sleeve is installed in impedor rear body.Impedor body, by draw rod attachment part 1,
Asymmetric round tube body 5, location division 10, scrape scar bar connecting portion 12 and form, draw rod attachment part,
Asymmetric round tube body, location division, scrape scar bar connecting portion be sequentially connected be made as one；Location division,
Screw is corresponding is shaped with detent 14 with location in its both sides, front end, detent for and location screw
Coordinate accurate stationary positioned set thus fixing tetrafluoro pillar and magnetic core.Impedor body central is axially made
Impedor mesopore 6, asymmetric round tube body is had to be shaped with water-guiding hole 3, impedor mesopore, water-guiding hole
For cooling down, current are logical to be cooled down magnetic core.Positioning sleeve, is a dumbbell shape positioning sleeve, its rear end
Portion is shaped with tetrafluoro pillar seat 15, and upper rear end is shaped with effluent trough 7, and effluent trough inner segment bottom surface is shaped with down
Domatic 8；The Caused by Sloping Surfaces that effluent trough and effluent trough inner segment bottom surface are shaped with, can make to cooling water flow out of smooth and easy,
Strengthen the cooling water impact dynamics to positioning sleeve concave part, the most thoroughly wash away drop onto herein molten
Drip, prevent molten drop accumulated plugging；Both sides, positioning sleeve front end are shaped with screw, and it is fixed to be all installed with in screw
Position screw 13.
The operation principle of the present invention is:
The present invention is applicable to produce small-bore steel pipes with straight, best results in diameter 30 to 200 millimeters.
In Welded Pipe Production Process, steel pipe weld bond, solder joint are molten condition, make in compression roller extruding
Under with, the steel plate two edges docking of tubulose is become to get up to form steel pipe.In the process, solder joint, weldering
Molten steel in molten condition at Kou, has molten drop drippage unavoidably, with the proal molten drop of steel pipe,
Just it is dropped in impedor positioning sleeve groove 9 position.Due between positioning sleeve groove and steel pipe inner wall
Having certain space, therefore molten drop is not easy to pile up and blocking.Particularly, now, from impedor
The cooling water that hole enters, enters magnetic core through water-guiding hole, the water outlet from positioning sleeve after cooling down magnetic core
Groove is that spurting flows out, and the Caused by Sloping Surfaces that effluent trough inner segment bottom surface is shaped with in addition can make cooling water flow out of
Smooth and easy, strengthen the cooling water impact dynamics to positioning sleeve groove position, the most thoroughly wash away and drop onto
Molten drop herein, is more effectively prevented from molten drop accumulated plugging.Prevent molten drop accumulated plugging phenomenon
Appearance, also ensure that cooling water flow out of smooth and easy, it is to avoid cause impedor owing to temperature is too high
The generation of the abnormal conditions such as effect reduces, electric energy loss increase；Prevent molten drop accumulated plugging, also
The problem fundamentally solving stuck parking, it is ensured that produce smooth and easy.
Although disclose embodiments of the invention and accompanying drawing for the purpose of illustration, but the technology of this area
Personnel are understood that without departing from the present invention and spirit and scope of the appended claims, various
Replace, to change and modifications be all possible, therefore, the scope of the present invention be not limited to embodiment and
Accompanying drawing disclosure of that.
