Abstract

A rebite comprises a nail core with a nail cap and a rivet pipe sleeved outside the nail core. A fracture is arranged in the nail core, a taper face is arranged on a portion of the nail core below the nail cap and extends downwards without exceeding the fracture position, and cross section area of the nail core at the position corresponding to the taper face portion is gradually increased downwards from the nail cap. A sub-taper-face attached to a portion of a cavity of the rivet pipe is arranged at a position corresponding to the taper face. The taper face can be a round table lateral face and can be expressed in other forms of cutting faces, and the sub-taper-face can be achieved in a molding method of stamping and forging. The rebite has the advantages of being good in riveting effect and high in safety.

Description

A kind of self-plugging rivet

(1) technical field

The utility model relates to a kind of self-plugging rivet.

(2) background technique

Self-plugging rivet is one type of rivet that blind riveting is used, and being specially adapted to the back is the riveted joint of the parts of closed area, and it uses special tool---hand riveter (manual, electronic, pneumatic) is riveted.As shown in Figure 1, the self-plugging rivet of existing technology comprises the nail core and the riveting pipe that is set in outside the nail core of a band head of a nail, and said nail core is provided with a fracture.During riveted joint, rivet nail core is spurred by special-purpose riveting gun, makes the riveting tube swelling, plays the riveted joint effect.And rivet can rupture at incision position naturally, makes rivet nail core tail end can come off not give prominence to and is treating on the riveting part.

But this type of rivet is when riveted joint, and it is irregular the distortion of riveting pipe to occur through regular meeting, has influence on riveting intensity, and the riveting pipe can directly take off from parts when serious, has influence on the Security of riveting pipe like this.

(3) summary of the invention

In order to overcome the deficiency of existing self-plugging rivet, the riveting pipe that the utility model provides a kind of riveting pipe to expand the type rule.

The technological scheme that the utility model solves its technical problem is: a kind of self-plugging rivet; The nail core and the riveting pipe that is set in outside the nail core that comprise a band head of a nail; Said nail core is provided with a fracture; Said nail core has the tapering face and extends not more than fracture site downwards on the position below the head of a nail, said nail core down becomes big at the cross sectional area of the facial position of corresponding tapering from the head of a nail gradually; The position of the corresponding tapering face of said riveting tube cavity is provided with the sub-tapering face of fitting with it.Described tapering face can be that frustum cone side can also be that the formal representation of other cutting face comes out, and said sub-tapering face can use the mode of punching press forging molding to realize.

Further, described tapering faces down and extends to fracture site, so that make.

A kind of selection, described tapering face are the anchor rings that a ring is firmly followed closely core, and the cross section of said nail core in the facial position of corresponding tapering is circle.

The another kind of selection, described tapering face are the tapered planes that terminates in the head of a nail that cuts on the nail core, and are evenly equipped with 4, can be with 4 side's punching presses, and the convenient manufacturings of mode such as cutting are to reduce manufacture cost.

Further, described riveting pipe is an aluminum component, and described nail core is a steel part, makes to be out of shape nature.

The utility model is consistent with the self-plugging rivet of existing technology in use.Owing to the existence of sub-tapering face, the bending of riveting Guan Zaizi tapering face end portion nature is deformed into bulging more regular accurate in deformation process.

The beneficial effect of the utility model is: rivet effective, safe.

(5) embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.

Embodiment 1

In conjunction with 2 one kinds of self-plugging rivet of accompanying drawing; The nail core 2 and the riveting pipe 3 that is set in outside the nail core 2 that comprise a band head of a nail 1; Said nail core 2 is provided with a fracture 4; Said nail core 2 has tapering face 5 and extends not more than fracture site downwards on the position below the head of a nail 1, described tapering face 5 is anchor rings that a ring is firmly followed closely core 2; Said nail core 2 down gradually becomes big for round and diameter from the head of a nail at the cross section of the facial position of corresponding tapering; The position of the corresponding tapering face of said riveting tube cavity is provided with the sub-tapering face 6 of fitting with it.

The utility model is consistent with the self-plugging rivet of existing technology in use.Owing to the existence of sub-tapering face 6, riveting pipe 3 is in the bending of sub-tapering face 6 end portions nature in deformation process, and it is more regular accurately to be deformed into drum, rivets effective.

Embodiment 2

In conjunction with accompanying drawing 3 to 5; A kind of self-plugging rivet comprises the nail core 2 of a band head of a nail 1 and is set in the riveting pipe 3 outside the nail core 2 that said nail core 2 is provided with a fracture 4; Said nail core 2 has tapering face 5 and extends downwardly into fracture site on the position below the head of a nail 1; Described tapering face 5 is the tapered planes that terminate in the head of a nail 1 that cut on the nail core, and is evenly equipped with 4, can 4 side's impact briquettings; Said nail core 2 down becomes big at the cross sectional area of the facial position of corresponding tapering from the head of a nail gradually; The position of the corresponding tapering face 5 of said riveting tube cavity is provided with the sub-tapering face 6 of fitting with it.

Described riveting pipe 3 adopts aluminum component, and described nail core adopts steel part, further optimizes and becomes drum shape and performance.

The utility model is consistent with the self-plugging rivet of existing technology in use.In deformation process because the existence of sub-tapering face 6, the bending of riveting Guan Zaizi tapering face 6 end portions nature, it is more regular accurately to be deformed into drum, rivets effective.
