Abstract

The invention discloses a kind of novel multilayer metal gasket connection structures, including pad, the pad is equipped with stomata or grease hole, bolt hole, its main feature is that, the pad by board group in upper plate, lower plate and multilayer at, the connecting portion of the upper plate and other plates is mitered into ligulate by tongue type blanking die, the corresponding position punching of plate in lower plate and multilayer, the some materials of the ligulate of upper plate form self-locking with plate in lower plate and multilayer, the some materials of ligulate stretch out lower plate, it will be connected with each other between plate in upper plate, lower plate and multilayer, form tongue type connection structure；The pad is equipped with stomata or grease hole, bolt hole；By tongue type connection structure, so as to effectively improve the bonding strength and efficiency of gasket, replace connection guard ring, reduce cost, improves efficiency and riveting quality.Present inventive concept is ingenious, design is reasonable, have many advantages, such as connectivity it is good, using reliable, effectively reduce the dislocation between each laminate of gasket, there is apparent technical advantage, application value and economic benefit.

Description

A kind of novel multilayer metal gasket connection structure

Technical field:

The present invention relates to connection type technical field between pad of engine multi-layered board, specifically a kind of novel multilayer gold Belong to pad connection structure, is a kind of structure for connecting multilayer metal gasket.

Background technique:

It is well known that gasket is for connection to the important spare part of engine associated components, gasket need to reliably seal high-temperature fuel gas Or lubricating oil and coolant liquid, the superiority and inferiority of gasket directly affect the performance of engine.

With the raising of emission request and power, the explosion pressure of engine by initial 12Mpa be increased to 16Mpa with On, up to 22Mpa.Existing multi-layer gasket generally uses guard ring to connect, and there are gap between guard ring and gasket, high detonation pressure is easy The transversion malposition of engine associated components is caused, so as to cause gasket dislocation, causes seal failure, and guard ring staking process takes When laborious, low efficiency.

Summary of the invention:

The purpose of the present invention is overcoming deficiency existing for above-mentioned prior art, and provide a kind of novel multilayer metal gasket connection Structure.

Technical solution provided by the invention is as follows: a kind of novel multilayer metal gasket connection structure, including pad, described Pad be equipped with stomata or grease hole, bolt hole, be characterized in that, the pad is by upper plate, lower plate and multilayer Board group is at the connecting portion of the upper plate and other plates is mitered into ligulate by tongue type blanking die, the plate in lower plate and multilayer Corresponding position punching, some materials and the plate in lower plate and multilayer of the ligulate of upper plate form self-locking, and some materials of ligulate are stretched Lower plate out will be connected with each other between plate in upper plate, lower plate and multilayer, form tongue type connection structure.

The beneficial effects of the present invention are: 1, by tongue type connection structure, so as to effectively improve the company of gasket, cylinder pad It connects intensity, reliability and efficiency, replaces connection guard ring, reduce cost, improve efficiency and riveting quality；2, structurally reasonable, connection Property it is good, using reliable, effectively reduce the dislocation between each laminate of gasket, there is apparent technical advantage, application value and economic effect Benefit.

Fig. 2 is the C portion riveting front enlarged drawing of Fig. 1；

Fig. 3 is the C portion riveting back side enlarged drawing of Fig. 1；

Fig. 4 is riveting position schematic diagram of the invention；

Fig. 5 is Fig. 4-A cut-away view.

Specific embodiment:

The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, not uses In limiting the scope of the invention.

As shown in Figure 1, 2, a kind of novel multilayer metal gasket connection structure, is made for pad 6 by 4 layers of metal plate Example；Pad 6 is made of upper plate 1, lower plate 4 and first median plate 2, second median plate 3；Upper plate 1 and the connecting portion of other plates are passed through Tongue type blanking die is mitered into ligulate 5, and the corresponding position of lower plate 4 and first median plate 2, second median plate 3 is rushed oblong aperture and (is also possible to Other shapes), it is then formed by mold tooling, some materials 7 of the ligulate 5 of upper plate 1 is expressed to first median plate 2, second Middle plate 3 and the lower section of lower plate 4, form self-locking, and some materials 7 of 1 ligulate 5 of upper plate stretch out lower plate 4, by upper plate 1, first median plate 2, the It is connected with each other between plate 3 and lower plate 4 in two, forms tongue type connection structure；Stomata or grease hole, bolt hole are machined on pad 6.

The novel multilayer metal gasket connection structure of one kind of the invention, by tongue type connection structure, so as to effective Raising gasket bonding strength and efficiency, replace connection guard ring, reduce cost, improve efficiency and riveting quality.

The foregoing is merely better embodiments of the invention, are not intended to limit the invention, all in spirit of the invention Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.

Claims

1. a kind of novel multilayer metal gasket connection structure, including pad (6), the pad (6) are equipped with stomata or oil Water hole, bolt hole, which is characterized in that the pad (6) is by board group in upper plate (1), lower plate (4) and multilayer at described is upper The connecting portion of plate (1) and other plates is mitered into ligulate (5) by tongue type blanking die, and plate is corresponding in lower plate (4) and multilayer Position punching, some materials (7) and the plate in lower plate (4) and multilayer of the ligulate (5) of upper plate (1) form self-locking, the portion of ligulate (5) Divide material (7) to stretch out lower plate (4), will be connected with each other between plate in upper plate (1), lower plate (4) and multilayer, forms tongue type connection structure.
