Abstract
The utility model discloses the shape welding nails that a kind of solderable ditch stitches position, including ailhead, nail rod, striking portion, it is connect at the top of ailhead and nail rod, nail rod bottom has striking portion, the nail rod both sides also have secondary nail rod and nail fin, the secondary nail rod is symmetrically distributed in nail rod both sides, and the lower edge for following closely fin and nail rod or so lateral edges, the lateral edges up and down of secondary nail rod and ailhead is connect, and follows closely fin covering from nail rod or so lateral edges to the distance of secondary nail rod outer end.The utility model has done special designing for ditch gap-like position butt welding nail, can be easy in ditch gap-like spots localization and melt is unfolded, and is sewed on to smoothly be welded to required ditch, with strong points, efficiently convenient.
Description
Technical field
The utility model belongs to electrical equipment field more particularly to a kind of shape welding nail at solderable ditch seam position.
Background technology
Tack welding（Arc stud welding）It is efficiently, the fusion of low cost, tunneling boring to weld the stud of 2 ~ 25mm of diameter or cylindrical metal
It is connected on a kind of special welding process of metal surface.Technique using some alternative traditional processing methods, example
Such as：Drilling, tapping, manual welding, after welding treatment.It is with the fusion of weld seam tunneling boring, the safety for improving welding position, hot shadow
Ring area is small, welding base metal deform small, welding damage is small, the base material back side without or the only welding damage of very little, holding hollow zero
The a series of advantage such as part seal.
Weldering nail is generally by rivet nut, striking portion, and some is also threaded or various spread grooves, or weldering nail hollow structure etc.,
Socket cap weldering nail is most commonly seen.However homogeneous is used due to its irregular thickness and shape for the occasion of certain ditches, seam, slot
Cylinder weldering nail is probably difficult to ensure that all sites can fully be welded in place, so, according to ditch, the shape needs of seam, slot.Greatly
Part ditch, seam, slot have deep narrow shallow wide shape design, therefore as impetus.
For this purpose, the utility model designs a kind of shape welding nail at suitable solderable ditch seam position.
Utility model content
Purpose of utility model：The utility model proposes the shape welding nails that a kind of solderable ditch stitches position, and ditch, seam etc. is made not to advise
Position then obtains intact welding, the deficiency of cylindric weldering nail is made up, to overcome problems of the prior art.
Utility model content：A kind of shape welding nail at solderable ditch seam position, including ailhead, nail rod, striking portion, ailhead with
There is striking portion, the nail rod both sides also to have secondary nail rod and nail fin, the secondary nail rod for connection at the top of nail rod, nail rod bottom
Be symmetrically distributed in nail rod both sides, nail fin and nail rod or so the lateral edges, secondary nail rod lateral edges up and down and ailhead under
Edge connects, and follows closely fin covering from nail rod or so lateral edges to the distance of secondary nail rod outer end.
Preferably, the nail rod cross section is ellipse, and elliptical long axis direction is consistent with nail fin extending direction.It is transversal
The ellipse and long axis and nail fin extending direction one in face cause its fusing to have extension tendentiousness.
Preferably, the quantity of the secondary nail rod is 5 ~ 8, and secondary nail rod stretches out the length of nail rod, is in from top to bottom
The trend first increase, reduced afterwards.Secondary nail rod quantity and extension elongation arrangement comply with seam, ditch, slot shape feature and
Tack welding technology characteristics.
Preferably, the 8.5 ~ 12% of a diameter of nail rod outer diameter of the secondary nail rod.Secondary nail rod is thinner than nail rod outer diameter,
So as to can keep certain form in fusing and quickly keep up with the rhythm of welding route.
Further, the thickness of the nail fin is 1.5 ~ 4mm, and its thickness successively decreases outward along nail rod edge.Follow closely the thickness of fin
Degree and its variation make it have good welding and crack performance.
Further, the ratio between the elliptical long axis of the nail rod cross section and short axle are 1.4 ~ 4.The ratio between transverse and short axle
Make it have preferable crack welding performance.
Further, the secondary nail rod along nail rod edge to overall diameter be in tendencies toward shrinkage.The contraction of secondary staple shank diameter
Trend makes it be merged with nail rod, is unlikely to the fast-falling in fusing.
Compared to the prior art, the beneficial effects of the utility model are：The utility model is simple in structure, the quick side of welding
Just, welding can have direction tendentiousness.Ailhead, the size of every section of nail rod and secondary nail rod, position and length arrangement, make
Fast homogeneous is easy under molten state；Nail fin has the effect of being positioned in fusing in crack, keeps tack welding technique quickly smart
It is accurate.The utility model for the butt welding of ditch gap-like position nail done special designing, can be easy ditch gap-like spots localization simultaneously
Melt is unfolded, is sewed on to smoothly be welded to required ditch, it is with strong points, it is efficiently convenient.

Fig. 1 is the structural schematic diagram of the utility model embodiment, and Fig. 2 is the cross section structure of the utility model embodiment nail rod
Schematic diagram.
In figure：1- ailheads, 2- nail rods, 3- strikings portion, 4- grade nail rod, 5- follow closely fin.
Specific implementation mode
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, letter will be made to embodiment below
Single introduction.
Such as Fig. 1 ~ 2, a kind of shape welding nail at solderable ditch seam position, including ailhead 1, nail rod 2, striking portion 3, ailhead 1 with
2 top connection of nail rod, 2 bottom of nail rod has striking portion 3；
2 both sides of the nail rod are also symmetrically distributed with secondary nail rod 4 and nail fin 5, and the secondary nail rod 2 is symmetrically distributed in nail rod
2 both sides, the 8.5 ~ 12% of 2 outer diameter of a diameter of nail rod of the secondary nail rod 4, the quantity of secondary nail rod 4 is 5 ~ 8, and secondary nail rod
4 stretch out the length of nail rods 2, be in from top to bottom first increase, the trend that reduces afterwards, it is the nail fin 5 and 2 or so lateral edges of nail rod, secondary
The lower edge connection of the lateral edges up and down and ailhead 1 of grade nail rod 4, and the covering of fin 5 is followed closely from 2 or so lateral edges of nail rod to secondary staple
The thickness of the distance of 4 outer end of bar, the nail fin 5 is 1.5 ~ 4mm, and its thickness successively decreases outward from 2 edge of nail rod；
2 cross section of the nail rod is ellipse, and elliptical long axis direction is consistent with nail 5 extending direction of fin, elliptical long axis
