CN2519865Y - Quick core-extracted rivet - Google Patents

Abstract

The utility model relates to a quick riveting core-extracted rivet which can enhance efficacy and is composed of a rivet bar and rivet bodies sheathed on the rivet bar, wherein the rivet bar is a cylinder; the rivet bodies are cylindrical; the ends of the rivet bodies are provided with cap edges. The utility model is characterized in that the rivet bar is a long cylinder, one end of the rivet bar is provided with a drum-shaped head of which the diameter is larger than that of the rivet bar; at least three rivet bodies are sheathed on the drum-shaped head and are identically arranged along a drum-shaped end direction. Under the effect of a pull rivet, the rivet bodies are bulged to clamp work pieces. After the drum-shaped head on the rivet bar end passes through the first rivet body, the drum-shaped head arrives at the end of the second rivet body to be secondarily riveted, and the continuous rivet connection is realized. The rivet bar can be used largely and repeatedly. The utility model improves the riveting effect, and can decreases the riveting cost effectively.

Description

Quick self-plugging rivet

The utility model relates to a kind of self-plugging rivet, specifically relates to a kind of self-plugging rivet that improves the quick riveted joint of effect.

In being connected and fixed between the metal of automobile industry, electron trade or sheet plastic, its Placement such as spot welding, screw, extruding fastening piece all need very big workload, in large batch of pipelining process, above-mentioned Placement will be paid very big cost, and effect is too low because riveted joint quantity is big.

Retrieve through new patent searching, a kind of open type arcuation self-plugging rivet is disclosed as 95246437.3, rivet body head by rivet body and the nail Open End Blind Rivet that core constituted is arch shape, and the head bottom surface that solves rivet body is not with folded closely connected by riveting parts, and influence is connected firm problem by riveting parts; Disclose a kind of Multigrip Type Blind Rivets as patent 94222991.6, it is made of mandrel nail and metal twin drum, has the twice groove on the mandrel nail; And for example patent 97181517.8 discloses a kind of blind rivet and manufacture method thereof.Thus, suchlike many patents, people improve the shearing resistance and the stretching resistance of riveted joint by the improvement of rivet body structure characteristic, improve sealing, anti-corrosive properties etc., do not raise the efficiency and the problem that reduces the riveted joint cost but attempt to solve.

The purpose of this utility model be exactly to provide a kind of efficiently, the self-plugging rivet of easy to operate quick riveted joint, it can reduce the riveted joint cost effectively.

In order to improve the effect of riveted joint, the technical solution adopted in the utility model is: a kind of quick self-plugging rivet, constitute by rivet bar and rivet body, rivet bar is a Cylinder, and rivet body is the garden cylindricality, in its end shade is arranged, rivet bar is long Cylinder, the one end has the diameter cydariform head bigger than rivet bar, and the rivet body that is enclosed within on the rivet bar is at least more than two, and along cydariform extreme direction aligned identical.

Be with the rivet bar of several rivet bodies, put in the special-purpose steam-operating riveting gun, under the effect of staking, under the situation that does not need other any back work, realize riveted joint continuously.

Because the utility model adopts technique scheme, therefore, has the following advantages:

1. rivet bar is an independently long Cylinder, at an end of rivet bar the plush copper of the diameter cydariform bigger than rivet bar is arranged, and rivet body can be arranged one by one in an orderly manner like this to be through on the rivet bar.

2. in special-purpose steam-operating riveting gun, under the effect of staking, the cydariform head of rivet rod end passes in the garden cylindricality of rivet body, and rivet body is expanded, the cydariform expanding volume of rivet body one end is bigger, thereby clamping work pieces after the cydariform head of rivet rod end passes first rivet body, arrives the end of second rivet body again, implement riveted joint for the second time again, under the situation that does not need other any back work, realize riveted joint continuously like this, improved the effect of riveted joint, can reduce the riveted joint cost effectively.

3. several rivet body riveted joints on the rivet bar finish, and can put on rivet body on rivet bar again, continue riveted joint, and rivet bar can be reused in a large number, till rivet bar cydariform head is by certain wearing and tearing, has improved efficient effectively, has reduced cost.

Fig. 1 is the structural representation of quick self-plugging rivet of the present utility model.

Fig. 2 is the structural representation of quick self-plugging rivet rivet body of the present utility model.

Fig. 3 is the structural representation of quick self-plugging rivet rivet bar of the present utility model.

Fig. 4 is the working state figure of quick self-plugging rivet of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing:

Rivet body 1, rivet body endoporus 101, rivet body shade 102, rivet bar 2, rivet bar cydariform head 201.

Formed by rivet body 1 and rivet bar 2 referring to Fig. 1 and the quick self-plugging rivet of Fig. 2 the utility model, rivet body is enclosed within on the rivet bar 2, rivet body 1 is the garden post shapes, the two ends of garden cylindricality rivet body 1 can be provided with shade 102, one end is extended with a shade that is mushroom-like, the other end has the cydariform than the slightly larger in diameter of the rivet body of garden cylindricality, and the through hole 101 of garden cylindricality is arranged in the rivet body 1.

Referring to Fig. 1 and Fig. 3, rivet bar 2 is independently long Cylinders, and the ailhead 201 of the cydariform of protrusion is arranged at the one end, and its diameter is bigger than rivet bar, and cover rivet body 1 thereon is at least more than two, and along cydariform end 201 direction aligned identical.In use, rivet body 1 is through on the rivet bar 2 singly, being about to rivet bar 2 penetrates in the garden cylindrical hole 101 in the rivet body 1, the quantity that is enclosed within the rivet body 1 on the rivet bar 2 also can reach many of 20-50, in actual production, rivet body 1 is arranged by same direction in an orderly manner, is fixed on and is convenient to packing into of rivet on the paper tape.

Referring to Fig. 4, during use, select the specification size of the quick rivet adapt according to the aperture on the riveted parts, then a string quick rivet is packed in the special tool, under the effect of staking, rivet bar moves backward, rivet body passes the cydariform head of rivet rod end, in the garden cylindrical hole between rivet body, pass again, make the cydariform of rivet body and rivet body one end produce the expansion change greatly, thus clamping work pieces, realize that riveted joint connects, the cydariform head of the rivet rod end of extracting out is blocked the state shown in Figure 1 that is reduced into by the cydariform of another rivet body end again, like this from a rivet body to just not doing any other back work another rivet body, realize riveted joint continuously.Just shift the time of rivet body.

Claims (1)

1. quick self-plugging rivet, constitute by rivet bar (2) and rivet body (1), rivet bar (2) is a Cylinder, rivet body (1) is the garden cylindricality, there is shade (102) end of rivet body (1), it is characterized in that: rivet bar (2) is long Cylinder, and an end has the diameter cydariform head (201) bigger than rivet bar, the rivet body (1) that is enclosed within on the rivet bar (2) is at least more than two, and along cydariform end (201) direction aligned identical.
