Description
Technical field
A kind of device and a kind of method that the present invention relates to a kind of blind rivet, be used to settle blind rivet.
Background technique
For a long time with regard to known tubular-shank rivet.Described tubular-shank rivet is used for two elements are connected to each other by means of the riveted joint process, does not wherein need to touch the back side.For this reason, tubular-shank rivet especially is suitable for use in the situation that can't touch two back sides that remain element connected to one another.In tubular-shank rivet commonly used, be necessary the shaft of rivet to be passed from this hole to there being element to be connected that the hole is set.Then from front tractive rivet mandrel, described rivet mandrel deforms to form rivet head rivet on overleaf.
The also known pointed tip configuration that the front at rivet of described mandrel is stretched is self-drilling tip, thereby can implement boring procedure in the process that has the riveted joint process with corresponding utensil.
In all known blind rivets, must be used to cause real riveted joint process settling the rivet mandrel of the part of tractive formation blind rivet afterwards.Instrumental purpose is used to carry out tractive on long mandrel, subsequently this mandrel is abandoned or is dropped to uncontrollably the position of riveting around.
Known in addition hammering rivet will have most advanced and sophisticated mandrel and insert in the boring in the shaft of rivet on described hammering rivet, described mandrel is stretched from the end face of flange with its more blunt end.Such rivet is squeezed into hammering.At this, hammer knocks on the end of stretching out of described mandrel.This hammering can not accurately at first be decomposed into power pure feed force and just be decomposed into expansionary force (US 3,691,924) subsequently.
Summary of the invention
Task of the present invention is to improve the scheme of blind rivet, thereby do not produce the waste material that must separately clear up after riveting.
For solving this task, the present invention proposes a kind of blind rivet and a kind of blind rivet that has in feature described in the claim 2 that has in feature described in the claim 1.Improvement project of the present invention is the theme of dependent claims.
Therefore the blind rivet that is proposed by the present invention has the shaft of rivet that has flange, and this flange then forms surface of contact, and described blind rivet lies on the upper side of parts with this surface of contact.The described shaft of rivet has positive end equally, and this end is stretched with enough yardsticks such as injecting to have in the parts to be connected and on an opposed side by the hole.If on the contrary with in the hole in the described blind rivet insertion parts and these parts thicker than the front region below the surface of contact of described flange of described blind rivet, then this blind rivet is stayed in the described hole, and does not stretch on an opposed side.In addition, described blind rivet comprises the acting surface of central authorities, applies effect on this acting surface, is used to make the part distortion of the described shaft of rivet, and this part of the described shaft of rivet is arranged on the opposed side of parts to be connected or stays in the hole.
As the effect that causes distortion, such as unexpected the moving of considering along equidirectional, during described blind rivet is just packed opening into along this equidirectional.This is a kind of scheme that how to form rivet head on an opposed side or in hole itself.
The another kind of scheme that is proposed by the present invention is the described acting surface of tractive.In this case, just temporarily be connected with described acting surface, and on this acting surface, carry out the tractive motion such as tappet or tractive element.Then after settling rivet head, unclamp once more and being connected of described tappet or tractive element.
In both cases, under the situation that is not installed in the mandrel on the rivet in advance, also enough deal with, thereby do not produce any waste material subsequently.
Should act on the region in front distortion that makes the described shaft of rivet on the acting surface of described central authorities, the acting surface of described central authorities can form on the end such as the hole in the described shaft of rivet.The depth ratio in this hole is as roughly being equivalent to two thickness that sheet material to be connected is arranged.Also can arrange like this, promptly this acting surface can be arranged more near the outer side surface of the flange of described blind rivet.
Can arrange so equally and such arrangement is in the scope of the present invention, promptly the acting surface of described central authorities is made of the position that narrows down that is in the hole in the described shaft of rivet or constitutes on the position that narrows down in hole.

Embodiment
Fig. 1 shows by the side view of the blind rivet of first mode of execution of the present invention and shows the sectional arrangement drawing of this blind rivet at right half part in left-half.This blind rivet comprises the shaft of rivet 1, has the shape of sleeve 2 in this shaft of rivet 1 zone therebetween.On an end above in Fig. 1, being in, on the shaft of rivet 1, formed a flange 3, this flange 3 has smooth downside 4.Described downside 4 is such sides, and described sleeve segment 2 begins from this side to extend.Described flange with described smooth downside 4 opposed upper sides 5 on form a smooth surface, this surface can be with the acting surface of the annular that acts on instrument.
The sleeve segment 2 of described centre extends on a side of its described dorsad flange 3 in the section 6 of front of the described shaft of rivet, has the cross section that reduces gradually at the shaft of rivet 1 described in this section 6.
Constructed columniform inside opening 8 in described sleeve segment 2, bypassed this inside opening this fact that not necessarily needs to come outbreak out and do not talk, this inside opening 8 can be called boring.But this opening has the shape of boring, that is to say to have circular cross section, and this cross section is constant on the length of described inside opening.Have the funnelform position 12 that narrows down on the end of described inside opening 8, this position 12 that narrows down then gradually becomes narrow slit 9.The end of described front can have two connection parts that part couples together in 9 both sides, described slit, makes described slit 9 directly also remain closed on the end of the front of the described shaft of rivet.
Arranged expanding body 10 in described inside opening 8, this expanding body 10 is resisted against on the edge of described inside opening 8 with certain clamping force.So fix this expanding body 10, make it when operating, can not drop out with described blind rivet.The end 11 of pointing to the inside of described inside opening 8 roughly is resisted against the place that begins at the described funnelform position 12 that narrows down.The outstanding significantly upper side 5 that surpasses the ring-type of described flange 3 in the end 13 of the opposed outside of described expanding body 10.Described expanding body so in depth can be positioned in the described inside opening 8 yet.
Fig. 2 shows at described blind rivet and the mutual corresponding relation between the instrument 14 shown in very simplifying.Described blind rivet can remain on the described instrument 14 in a kind of mode that is not shown specifically, and makes it to pack in the hole 15 of two blocks of sheet materials 18,19 of placing up and down by the operation of carrying out with described instrument 14.Described instrument comprises an endoporus 16, in this size that so designs this endoporus 16, makes the part 14a that is configured to sleeve shape in its region in front of described instrument 14 to act on from the next door of described expanding body 10 on the upper side 5 of described flange 3.In this mutual corresponding relation, make described blind rivet as mentioning already from as described in pass the hole 15.Produce as position shown in Figure 3 at this.Now, in another job step, the endoporus 16 that makes tappet 20 pass described instrument 14 suddenly travels forward.This tappet 20 impacts with the end face 21 of its front on the end face 13 of outside of described expanding body 10, and with this expanding body 10 to the previous dynasty described inside opening 8 inside advance.This state is shown in Figure 3.
If the described position 12 that narrows down is run in the end 11 of the front of described expanding body 10 on the end of described inside opening 8, two of the end 6 of the front of the so described shaft of rivet or more a plurality of part will outwards be out of shape.This realizes by described slit 9.Because two of the end of described front 6 or more a plurality of part are connected to each other in front, thus these parts can not tear each other, but as shown in Figure 4 formation rivet head 22.In this state, the end face 13 of the outside of described tappet 10 is in the plane identical with the upper side of the flange 3 of the described shaft of rivet.The rivet head 22 that forms obtains thickening in inside by described expanding body 10.Take off described instrument now, and produce a kind of rivet now and connect, this rivet connects and looks the same with shown in the side view of Fig. 5.Described expanding body 10 is no longer stretched from the observable upper side 5 of described flange 3.If that is to say from above in Fig. 5 to connect, just be bound to find whether this end face 13 extends with the upper side 5 of described flange with flushing from the described rivet of top observation.If it is too dark that it enters, will infer therefrom that so sometimes the resistance that produces with respect to feed movement is too little in the described shaft of rivet.This may represent that the firm degree of described connection is not enough.In this regard, described expanding body 10 has formed and has settled check.
