Description
Technical field
The present invention relates to welding jig field, more particularly to a kind of flat tips of PFA.
Background technology
PFA is also known as tetrafluoroethene, and long-time service temperature is -80--260 degree, there is remarkable chemical resistance, to all
Chemicals is all corrosion-resistant, and coefficient of friction is minimum in the plastic, also has good electrical property, and electrical insulating property is not affected by temperature,
There is the title of " King ", PFA has been widely used in making corrosion protective lining inside tank car, spread due to its good corrosion resistance
If it is frequently necessary to together connect tetrafluoro board material splice with being laid on after the welding rod fusing close with tetrafluoro plate material during lining
At seam, so as to which plate be connected, common welding method has hot gas welding and thermocompression bonding, and worker need to ensure welding rod in welding
The seam that can be paved with straight after fusing between plate, but in practical operation, it is desirable to the straight line welding for reaching absolute is not
It is possible, it, all can there are left-right deviations in welding no matter how high the level of skill of operator is.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of flat tips of PFA, to solve on caused by the prior art
State multinomial defect.
To achieve the above object, the present invention provides following technical solution：A kind of flat tips of PFA, including casing, the set
Pipe is equipped with locking nut, and described sleeve pipe front end is equipped with discharge pipe, and the discharge pipe is equipped with guide pipe, the guiding tube section
For flat rectangular surfaces, the guide pipe one side is equipped with Y stents.
Preferably, the two fulcrum line of Y stent ends and discharge pipe centerline axis parallel.
It is using the advantageous effect of above technical scheme：The flat tips of a kind of PFA of the present invention, using needing to be equipped with during this tip
A piece section is the gib block of L-shaped, and the casing of this tip is sleeved at the air outlet of hot air welding gun, and screws locking nut and fixes
Two blocks of tetrafluoro lining plates are close together by firmly tip, when welding, and discharge pipe is placed on seam crossing, first finds the correct of gib block
Position, gib block are placed on the lower section of Y stent ends at this time and are placed in parallel with seam, start welding work after fixing gib block
Industry, when welding, lean against Y stent ends in the dog-ear of gib block, and one hand of worker holds hot air welding gun, and another hand is by welding rod
Go out from guide pipe and slowly stretch into, while one end of slave seam slowly slides into the other end, hot wind is spread after tetrafluoro welding rod is melted
It is located in the seam of plate, so as to fulfill to the welding between plate, worker is in mobile welding gun since Y stents are always against leading
Moved to item, and gib block is parallel with seam, therefore the path that welding gun is passed by is parallel with gib block, overlapped with seam and
On same straight line, the present apparatus is simple in structure, and cost is extremely low, effectively solves the problems, such as that left-right deviation occurs during human weld, makes one
A bit can only human weld region can reach machine welding high quality level.
Description of the drawings
Fig. 1 is the side view of the present invention；
Fig. 2 is the top view of the present invention；
Fig. 3 is the gib block schematic diagram of the present invention.
Wherein, 1- casings, 2- discharge pipes, 3- guide pipes, 4- stents, 5- locking nuts, 6- gib blocks.
Specific embodiment
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
Fig. 1-3 shows the specific embodiment of the present invention：A kind of flat tips of PFA, including casing 1, described sleeve pipe 1 is equipped with
Locking nut 5,1 front end of described sleeve pipe are equipped with discharge pipe 2, and the discharge pipe 2 is equipped with guide pipe 3, and 3 section of guide pipe is
Flat rectangular surfaces, 3 one side of guide pipe are equipped with Y stents 4.
In the present embodiment, 4 end of Y stents, the two fulcrum line and 2 centerline axis parallel of discharge pipe, Y stents 4 during welding
During against gib block 6, the central axes of tip are also overlapped with seam, and tip during welding is avoided to tilt discharging, influences weldquality.
A use of section need to be equipped with during this tip is L-shaped based on a kind of above-mentioned, the flat tips of PFA of structure of the present invention
The casing 1 of this tip is sleeved at the air outlet of hot air welding gun by gib block 6, and is screwed locking nut 5 and fixed tip, welding
When two blocks of tetrafluoro lining plates are close together, discharge pipe 2 is placed on seam crossing, first finds the correct position of gib block 6, be oriented to
Item 6 is placed on the lower section of 4 end of Y stents at this time and is placed in parallel with seam, starts weld job, weldering after fixing gib block 6
4 end of Y stents is leaned against in the dog-ear of gib block 6 when connecing, one hand of worker holds hot air welding gun, and another hand is by welding rod from leading
Go out to pipe 3 and slowly stretch into, while one end of slave seam slowly slides into the other end, hot wind is laid on after tetrafluoro welding rod is melted
In the seam of plate, so as to fulfill to the welding between plate, worker is in mobile welding gun since Y stents 4 are always against guiding
Item 6 moves, and gib block 6 is parallel with seam, therefore the path that welding gun is passed by is parallel with gib block 6, overlapped with seam and
On the same line, the present apparatus is simple in structure, and cost is extremely low, effectively solves the problems, such as that left-right deviation occurs during human weld, makes
Some can only human weld region can reach machine welding high quality level.
Above-described is only the preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection domain.
