Embodiment
Describe embodiment of the present utility model in detail below in conjunction with the accompanying drawings.
It is provided by the utility model be used for connect metallic plate from puncture steel nail, be it is a kind of can wide application one kind
Can self-piercing riveting steel nail, be particularly suitable for use in the connected mode between aluminium alloy plate or magnesium alloy plate and steel plate.Concrete application side
Method is that steel nail pierces through upper strata aluminium alloy plate or magnesium alloy plate and riveting enters first with puncturing certainly, then regard steel nail as medium and lower floor
Steel plate welding.
Shown in Fig. 1-Fig. 7 is embodiment one of the present utility model, for connecting having from puncture steel nail 100a for metallic plate
There is head 110a, extend the shank 120a of formation from the 110a of head, and the forked tail platform formed is extended by shank 120a end
130a.The cross section of the forked tail platform 130a is in up-narrow and down-wide tie rod linkage, and the radial dimension of its maximum is than shank 120a
The big 0.2~0.5mm of radial dimension.Forked tail platform 130a end plane periphery is provided with some cutting edge 134a, forms a cutting flat
Face 132a, so as to be easier to puncture metallic plate 200a.
Further, head 110a and shank 120a one end contacted are arranged to the anti-recessed structure to head 110a directions,
The angle of anti-recessed structure is 0~7 degree, so that steel nail is reaching preferably left-hand thread effect from puncture process.Fig. 2 is anti-recessed knot
The partial enlarged drawing of structure.
Further, the radius R of thin silk fabric line is cut provided with cutting thin silk fabric line in forked tail platform 130a end plane periphery<
0.3mm, so as to increase frictional force, prevents from rotating in the application from puncture steel nail 100a.
From steel nail 100a is punctured when in use, it is necessary to aid in installing by mould 400a, so that puncturing steel nail 110a certainly
Smoothly directly pass through from metallic plate 200a precalculated position.As shown in figure 3, mould 400a has mold convexity 410a and relief hole
420a.During installation, mould 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 mould 400a.Then pressure head portion 110a, shank are clapped
The forked tail platform 130a of 120a ends is punctured in metallic plate 200a precalculated position, the cutting edge 134a on forked tail platform 130a end planes
Metallic plate 200a is punched, the waste material under punching is discharged by mould 400a relief hole 420a, while mold convexity 410a is extruded
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 more closely connected so as to realize with wrapping shank 120a from puncture steel nail 100a with metallic plate 200a.
From puncturing after steel nail 100a insertion metallic plates 200a, forked tail platform 120a end 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 puncture process is punctured certainly
The groove 210a of upper formation, acts not only as the storage pool of liquation during metal welding, and the contact surface of welding is increased,
Welding operation is allowed to be easier.That shown in Fig. 5 is two panels metallic plate 200a, the schematic diagram after 300a welding.
Further, from puncture steel nail 100a can be with disposable puncture two panels metallic plate, so that using steel nail in itself
The riveting of two panels metallic plate is got up from punching, as shown in Figure 6.Passed through from steel nail 100a is punctured after two panels metallic plate, forked tail platform 120a
End protruded from second metallic plate, so as to be welded with three-piece metal plate.
Further, described be integrally formed from puncture steel nail 100a by shaping solid steel is made.
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, are specifically determined according to actual conditions such as the thickness of metallic plate.
Further, it is described to have metal coating from the surface for puncturing steel nail 100a.
As shown in Fig. 8-Figure 13, in embodiment two of the present utility model, from the head 110b and handle for puncturing steel nail 100b
A flange 112b is provided with the middle of portion 120b.When being stamped from puncture steel nail 100b, flange 112b extruding metal blanks wrap it
Wrap shank 120b, so as to add from the bonding strength for puncturing steel nail 100b and metallic plate 200b, be particularly suitable for use in connection compared with
Thick metallic plate or the metallic plate of more than two.Shown in Fig. 9 is flange 112b partial enlarged drawing.Worn certainly in embodiment two
Pierce steel nail 100b other structures feature be the same as Example one.
As shown in Figure 14-Figure 19, in embodiment three of the present utility model, from the head 112c and handle for puncturing steel nail 100c
Some 30~45 degree of diagonal bar 122c is provided between portion 120c.During being pushed from puncture steel 100c, diagonal bar 122c is rushed
Connection is set more to fasten in press-in metallic plate 200c, while can play prevents from, from the effect that steel nail 100c is rotated is punctured, especially fitting
For needing to prevent the occasion that steel nail is rotated, such as steel nail head is with situations such as studs.Shown in Figure 15 be diagonal bar 122c just
Face and the partial enlarged drawing of side.It is preferred that being provided with three diagonal bar 122c from steel nail 100c is punctured.From puncture in embodiment three
Steel nail 100c other structures feature be the same as Example one.
It should be noted that above content be combine specific embodiment the utility model is made it is further in detail
Explanation, it is impossible to assert that embodiment of the present utility model is only limitted to this, under above-mentioned guidance of the present utility model, this area
Technical staff can carry out various improvement and deformation on the basis of above-described embodiment, and these are improved or deformation falls in this reality
