Abstract

The utility model discloses a special rivet structure for an elastic piston ring of a dust removal cloth bag, which comprises a nail cap, wherein a solid nail column is fixedly arranged at the bottom of the nail cap, and a hollow groove is fixedly arranged at one end, far away from the nail cap, of the solid nail column. This kind of special rivet structure nut top of dust removal sack elastic expansion ring is level and smooth, thickness is suitable, do not influence the use of later process after the riveting, the main fixed elastic expansion ring of solid nail post, guarantee intensity after the riveting, hollow groove makes the tip of solid nail post take place deformation easily, rivet more easily, the degree of depth in hollow groove has also carried out rational design according to the thickness of elastic expansion ring simultaneously, consequently, the nut thickness that forms after the riveting is thinner, can not exert an influence to subsequent processing, according to difficult point in the production process, combine dust removal sack applied environment and technological requirement simultaneously, carry out optimal design to common rivet structure, this rivet structure has been produced, be applied to the sack dust removal trade.

Description

Special rivet structure of dust removal sack elastic expansion ring

Technical Field

The utility model relates to the technical field of rivets, in particular to a rivet structure special for an elastic piston ring of a dust removal cloth bag.

Background

A common rivet structure on the market consists of a hemispherical nut and a solid stud. The common dust-removing cloth bag is applied to the working condition environment with high temperature and corrosive gas, so the rivets on the elastic piston ring of the cloth bag have to resist high temperature and corrosion and have enough strength. At present, stainless steel solid rivets are commonly used in the cloth bag dust removal industry, but solid rivet columns are hard, a punching pin of automatic riveting equipment is easy to break, the automatic riveting equipment is difficult to use, most processing plants can only adopt manual striking to rivet steel belts, the production efficiency is low, and the riveting quality is difficult to guarantee. Therefore, we improve the structure and provide a special rivet structure for the elastic piston ring of the dust removal cloth bag.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems, the utility model provides the following technical scheme:

the utility model relates to a special rivet structure for an elastic piston ring of a dust removal cloth bag, which comprises a rivet cap, wherein a solid rivet column is fixedly arranged at the bottom of the rivet cap, and a hollow groove is fixedly arranged at one end, far away from the rivet cap, of the solid rivet column.

As a preferable technical scheme of the utility model, the top of the nail cap is flat.

As a preferred technical scheme of the utility model, the nail cap and the solid nail column are made of stainless steel materials.

The utility model has the beneficial effects that:

this kind of special rivet structure of dust removal sack elastic expansion ring, the nut top is level and smooth, thickness is suitable, and the riveting is thick does not influence the use of later process, and solid post mainly fixes the elastic expansion ring, the intensity after the guarantee riveting, and hollow groove makes the tip of solid post take place deformation easily, and riveting more easily, and the degree of depth in hollow groove has also carried out rational design according to the thickness of elastic expansion ring simultaneously, and consequently the nut thickness that forms after the riveting is thinner, can not exert an influence to subsequent processing.

Drawings

The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiments of the utility model and together with the description serve to explain the principles of the utility model and not to limit the utility model. In the drawings:

FIG. 1 is a schematic structural diagram of a main body of a rivet structure special for an elastic piston ring of a dust removal cloth bag;

FIG. 2 is a schematic view of a rivet riveting structure of the special rivet structure for the elastic piston ring of the dust removal cloth bag.

In the figure: 1. a nail cap; 2. solid nail posts; 3. a hollow groove.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Example (b): as shown in figures 1-2, the rivet structure special for the elastic piston ring of the dust removal cloth bag comprises a rivet cap 1, a solid post 2 is fixedly arranged at the bottom of the rivet cap 1, a hollow groove 3 is fixedly arranged at one end, far away from the rivet cap 1, of the solid post 2, the solid post 2 is mainly used for fixing the elastic piston ring, the strength after riveting is guaranteed, the end of the solid post 2 is easy to deform and rivet through the hollow groove 3, and meanwhile, the depth of the hollow groove 3 is reasonably designed according to the thickness of the elastic piston ring, so that the rivet cap 1 formed after riveting is thinner, and the subsequent processing cannot be affected.

The top of the nail cap 1 is flat, the top of the nail cap 1 is flat and smooth, the thickness of the nail cap is proper, and the riveting thickness does not influence the use of the next procedure.

Wherein, the nail cap 1 and the solid nail column 2 are both made of stainless steel materials, and the stainless steel materials can increase the strength of the nail cap 1 and the solid nail column 2.

The working principle is as follows: this kind of special rivet structure of dust removal sack elastic expansion ring, 1 top of nut is level and smooth, thickness is suitable, the riveting is thick does not influence the use of later process, the main fixed elastic expansion ring of solid nail post 2, guarantee intensity after the riveting, hollow groove 3 makes the tip of solid nail post 2 take place deformation easily, rivet more easily, the degree of depth in hollow groove 3 has also carried out rational design according to the thickness of elastic expansion ring simultaneously, consequently, 1 thickness of nut that forms after the riveting is thinner, can not produce the influence to subsequent processing, according to the difficult point in the production process, combine dust removal sack applied environment and technological requirement simultaneously, carry out optimal design to common rivet structure, this rivet structure has been produced, be applied to the sack dust removal trade. The special rivet for the elastic expansion ring of the dust removal cloth bag has the advantages of simple and reasonable structure, novel design, high practical value and wide popularization value.
