Specific implementation mode
The specific implementation mode that the invention will now be described in detail with reference to the accompanying drawings.
It is provided by the present invention for connect metallic plate from puncture steel nail, be it is a kind of can wide application one kind can from
The steel nail that sleeving and riveting connects, especially suitable for the connection type between aluminium alloy plate or magnesium alloy plate and steel plate.Concrete application method is
Upper layer aluminium alloy plate or magnesium alloy plate are pierced through with puncture steel nail certainly first and riveting enters, then using steel nail as the steel of medium and lower layer
Plate welds.
Fig. 1-shown in Fig. 7 is the embodiment of the present invention one, and the steel nail 100a that punctures certainly for connecting metallic plate has head
Portion 110a, the shank 120a extended to form from the 110a of head, and the forked tail platform 130a that is extended to form by the end of shank 120a.
The cross section of the forked tail platform 130a is in up-narrow and down-wide tie rod linkage, radial direction of the radial dimension than shank 120a of maximum
Big 0.2~the 0.5mm of size.The end plane periphery of forked tail platform 130a is equipped with several cutting edge 134a, forms a cutting planes 132a,
To be easier to breakdown metallic plate 200a.
Further, head 110a is arranged to the anti-recessed structure to the head directions 110a with the one end contacted shank 120a,
The angle of anti-recessed structure is 0~7 degree, to make steel nail reach preferably left-hand thread effect from piercing process.Fig. 2 is anti-recessed knot
The partial enlarged view of structure.
Further, it is equipped with cutting thin silk fabric line in the end plane periphery of forked tail platform 130a, cuts the radius R of thin silk fabric line<
0.3mm prevents from rotating in the application from puncture steel nail 100a so as to increase frictional force.
From steel nail 100a is punctured when in use, need through mold 400a auxiliary installations, to make from puncture steel nail 110a
Smoothly directly pass through from the precalculated position of metallic plate 200a.As shown in figure 3, mold 400a has mold convexity 410a and relief hole
420a.When installation, mold 400a is located at from the lower section for puncturing steel nail 100a, relief hole 420a and the shank for puncturing steel nail 100a certainly
120a is aligned, and metallic plate 200a is placed on from the centre for puncturing steel nail 100a and mold 400a.Then pressure head portion 110a, shank are clapped
The forked tail platform 130a of the ends 120a is punctured in the precalculated position of metallic plate 200a, the cutting edge 134a on forked tail platform 130a end planes
It is punched metallic plate 200a, the waste material under being punched is discharged by the relief hole 420a of mold 400a, while mold convexity 410a is squeezed
Metallic plate 200a forms groove 210 on metallic plate 200a and squeezes into the metal blank squeezed out from the handle for puncturing steel nail 100a
Portion 120a is to wrap shank 120a, to realize from puncture steel nail 100a and connection closer metallic plate 200a.
From after puncturing steel nail 100a insertion metallic plates 200a, the end of forked tail platform 120a is protruded from metallic plate 200a, such as
Shown in Fig. 4, so as to be welded with second metallic plate 300a.And metallic plate 100a in steel nail 100a piercing process is punctured certainly
The groove 210a of upper formation, acts not only as the storage pool of melt when metal welding, and the contact surface of welding is increased,
Welding operation is allowed to be easier.Shown in fig. 5 is two panels metallic plate 200a, the schematic diagram after 300a welding.
It further, can be with disposable puncture two panels metallic plate, to utilize steel nail itself from puncture steel nail 100a
The riveting of two panels metallic plate is got up from punching, as shown in Figure 6.From after puncture steel nail 100a passes through two panels metallic plate, forked tail platform 120a
End protruded from second metallic plate, so as to be welded with third piece metallic plate.
Further, described to be made from puncture steel nail 100a of the integrated molding of shaping solid steel.
The metallic plate 200a, 300a can be all kinds of sheet metals such as aluminium alloy plate, magnesium alloy plate, steel plate.
The length of the shank 120a and forked tail platform 130a, the actual conditions such as thickness according to metallic plate specifically determine.
Further, described to have metal coating from the surface for puncturing steel nail 100a.
As shown in Fig. 8-Figure 13, in the embodiment of the present invention two, from the head 110b and shank for puncturing steel nail 100b
A flange 112b is equipped among 120b.When being stamped from puncture steel nail 100b, flange 112b, which squeezes metal blank, makes its package
It is thicker to be particularly suitable for connection to increase from the bonding strength for puncturing steel nail 100b and metallic plate 200b by live in shank 120b
Metallic plate or two or more metallic plates.Shown in Fig. 9 is the partial enlarged view of flange 112b.From puncture in embodiment two
The other structures feature of steel nail 100b is the same as embodiment one.
As shown in Figure 14-Figure 19, in the embodiment of the present invention three, from the head 112c and shank for puncturing steel nail 100c
Several 30~45 degree of diagonal bar 122c is equipped between 120c.During from steel 100c pushings are punctured, diagonal bar 122c is stamped
Entering in metallic plate 200c makes connection more fasten, while can play the effect prevented from steel nail 100c rotations are punctured, especially suitable
In the occasion for needing to prevent steel nail from rotating, for example steel nail head is with situations such as studs.Shown in figure 15 is the fronts diagonal bar 122c
With the partial enlarged view of side.Preferably, being provided with three diagonal bar 122c from steel nail 100c is punctured.From puncture steel in embodiment three
The other structures feature of 100c is followed closely with embodiment one.
It should be noted that the above content is combine specific embodiment made for the present invention further specifically
It is bright, and it cannot be said that specific implementation mode of the invention is only limitted to this, under the above-mentioned guidance of the present invention, those skilled in the art can
To carry out various improvement and deformations on the basis of the above embodiments, and these are improved or deformation falls the protection model in the present invention
In enclosing.
