Description

Punching rivet structure

Technical Field

The utility model relates to a rivet connection technical field specifically is a punching press rivet structure.

Background

The punching is a forming processing method for applying external force to a plate, a strip, a pipe, a section bar and the like by a press machine and a die to cause plastic deformation or separation, so as to obtain a workpiece (a punching part) with a required shape and size.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a punching press rivet structure to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a punch rivet structure includes a plate and a rivet;

the middle part of the plate is provided with a circular hole, a cylinder is connected in the circular hole, a limiting ring is fixedly connected to the side wall of the cylinder opposite to the rivet, and the limiting ring is used for clamping the rivet;

and the side wall of the limiting ring, which is opposite to the rivet, is fixedly connected with an arc-shaped clamping plate.

As a further aspect of the present invention: the cylinder and the circular hole are connected through an arc-shaped plate.

As a further aspect of the present invention: a gap is reserved between the horizontal arc-shaped clamping plates.

As a further aspect of the present invention: a space is reserved between the vertical arc-shaped clamping plates.

As a further aspect of the present invention: and the side wall of the arc-shaped clamping plate, which is opposite to the rivet, is fixedly connected with a locking tooth.

As a further aspect of the present invention: one end fixedly connected with solid fixed cylinder of locking tooth, gu fixed cylinder fixed connection is on arc chucking plate.

As a further aspect of the present invention: a groove is formed in the arc-shaped clamping plate, and one end of the fixed cylinder is fixedly connected into the groove.

As a further aspect of the present invention: an annular space is reserved between the locking teeth and the fixed cylinder.

Compared with the prior art, the beneficial effects of the utility model are that: the staff passes and makes the upper end of rivet be located the top of drum with the one end top-down of rivet in the drum, later the staff extrudees the drum and makes the drum move to the rivet, thereby make the inside wall of spacing ring move to the rivet, thereby realize that the locking tooth blocks the rivet, the phase transition probably takes place for the in-process arc chucking plate with the rivet chucking at the locking tooth, because be provided with space and space from not influencing the emergence deformation of arc chucking plate at chucking rivet in-process, simultaneously at the in-process of locking tooth with the rivet chucking, the locking tooth is probably to take place deformation, because the setting of annular space does not influence the locking tooth and takes place deformation.

The punching rivet structure can not generate the phenomenon that the rivet is loosened when the rivet is connected on the plate.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, in an embodiment of the present invention, a punch rivet structure includes a plate 1 and a rivet 2;

the middle part of the plate 1 is provided with a circular hole 3, a cylinder 4 is connected in the circular hole 3, a limiting ring 5 is fixedly connected to the side wall of the cylinder 4 opposite to the rivet 2, and the limiting ring 5 is used for clamping the rivet 2;

the side wall of the limit ring 5 opposite to the rivet 2 is fixedly connected with an arc-shaped clamping plate 6.

The cylinder 4 is connected with the circular hole 3 through the arc-shaped plate 7, and the limiting cylinder 4 is connected in the circular hole 3 through the arc-shaped plate 7.

A gap 8 is reserved between the horizontal arc-shaped clamping plates 6.

A space 9 is reserved between the vertical arc-shaped clamping plates 6.

The side wall of the arc-shaped clamping plate 6 opposite to the rivet 2 is fixedly connected with a locking tooth 10.

One end of the locking tooth 10 is fixedly connected with a fixed cylinder 11, and the fixed cylinder 11 is fixedly connected on the arc-shaped clamping plate 6.

A groove is formed in the arc-shaped clamping plate 6, and one end of the fixed cylinder 11 is fixedly connected into the groove.

An annular space 12 is reserved between the locking tooth 10 and the fixed cylinder 11.

The utility model discloses when using, the staff passes and makes rivet 2's upper end be located drum 4's top from drum 4 with the one end top-down of rivet 2, later staff's extrusion drum 4 makes drum 4 remove to rivet 2, thereby make the inside wall of spacing ring 5 remove to rivet 2, thereby realize that locking tooth 10 blocks rivet 2, locking tooth 10 is with the in-process arc chucking plate 6 of rivet 2 chucking probably take place the phase transition, because be provided with space 8 and space 9 from not influencing the emergence deformation of arc chucking plate 6 at chucking rivet 2 in-process, simultaneously at the in-process of locking tooth 10 with rivet 2 chucking, locking tooth 10 is probably out of shape, because annular space 12's setting does not influence locking tooth 10 and takes place out of shape.

"fixedly connected" as described in the present invention means that two parts connected to each other are fixed together, typically by welding, screwing or gluing; "rotationally coupled" means that two components are coupled together and capable of relative motion.

Although the present description is described in terms of embodiments, not every embodiment includes only a single embodiment, and such description is for clarity only, and those skilled in the art should be able to integrate the description as a whole, and the embodiments can be appropriately combined to form other embodiments as will be understood by those skilled in the art.

Therefore, the above description is only a preferred embodiment of the present application, and is not intended to limit the scope of the present application; all changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
