Description

Double-drum type loose core rivet

The utility model relates to the coupling rivet that a kind of fixed component is used, and specially refers to a kind of Multigrip Type Blind Rivets.

The conventional rivets of using is subjected to the restriction of riveting parts thickness at present, and thick more as the thickness of riveted plating, the intensity of rivet is low more, and Security is lower.Problem such as therefore, exist to use and external form is coarse single.Along with the development of Chinese national economy and the raising of people's living standard, the decoration decoration project engineering that needs in vast town and country develops very fast, is badly in need of providing a large amount of rivets that decoration decoration project engineering is used that satisfy in the market.Therefore, state is in order to satisfy the needs in market, for developing a kind of difunctional, high strength and modern design Multigrip Type Blind Rivets attractive in appearance, is very necessary.

The purpose of this utility model: in order to overcome above-mentioned technical problem, and provide a kind of Multigrip Type Blind Rivets.This rivet, during as the riveted joint slab, the available first drum riveted joint; As when riveting thin plate, the available second drum riveted joint.Have characteristics such as difunctional, that riveting intensity is high, usage safety performance good, modern design is attractive in appearance and have wide range of applications.

In order to realize this purpose, invention scheme of the present utility model is: in Figure of description, Fig. 1 provides the structural representation of this Multigrip Type Blind Rivets, it mainly is made of mandrel nail (1) and metal twin drum (2), Fig. 2 provides the structural representation of mandrel nail (1), and wherein (1-1) is groove.The production and processing technology process of this Multigrip Type Blind Rivets: at first on mandrel nail (1), process twice groove (1-1) in advance, use special purpose machinery then, the surface that twice groove (1-1) on mandrel nail (1) is located and outside on the garden, the metal aluminium is located to push inwards toward twice groove (1-1), compress simultaneously, promptly make metal twin drum (2), and make this Multigrip Type Blind Rivets.About the specific structural features of Fig. 1 and Fig. 2 and embodiment are illustrated in the Figure of description explanation.

Advantage of the present utility model:

A kind of Multigrip Type Blind Rivets, it mainly by mandrel nail (1) and metal twin drum (2) constitute processing technology and simple in structure.It has difunctional, during as the riveted joint slab, and the available first drum riveted joint; As when riveting thin plate, the available second drum riveted joint, the riveting intensity height, usage safety performance is good, profile is neat and artistic, modern design, have wide range of applications, owing to adopt the production of self-control special purpose machinery, manufacturing efficiency improves, and characteristics such as is suitable for producing in enormous quantities and easy to implement.

Below in conjunction with Figure of description, specific structural features of the present utility model and embodiment are described further:

Fig. 1 provides the structural representation of this Multigrip Type Blind Rivets, also is the specification digest accompanying drawing.It mainly is made of mandrel nail (1) and metal twin drum (2).

Fig. 2 provides the structural representation of mandrel nail (1), and wherein (1-1) is groove.

The production and processing technology process of this Multigrip Type Blind Rivets: at first adopt special purpose machinery, on mandrel nail (1), process twice groove (1-1) in advance, and the mandrel nail (1) that will have twice groove (1-1) cleans and annealing in process, use homemade special purpose machinery and mould then, the surface that twice groove (1-1) on mandrel nail (1) is located and outside on the garden, the metal aluminium is located to squeeze inwards toward twice groove (1-1), compress simultaneously, promptly make metal twin drum (2), and be made into Multigrip Type Blind Rivets.It is highly polished and neat and artistic to have profile, and modern design has wide range of applications, owing to adopt the production of self-control special purpose machinery, manufacturing efficiency improves, and is suitable for producing in enormous quantities, satisfies the needs in market.

Promptly constitute the utility model according to above-mentioned making---a kind of Multigrip Type Blind Rivets.
