Description
Technical field
The invention belongs to sheet material interconnection technique field, and in particular to a kind of compound using the precompressed hole of soft riveting post and riveting
Sheet material connection method.
Background technology
In recent years, the sheet material connectivity problem of same material, foreign material, same thickness and different-thickness had obtained extensive pass
Note.Poor using the sheet material Joining Technology of rivet interlacement, rivet can produce damage to plate surface, have a strong impact on the use effect of sheet material
Fruit, further, since rivet and sheet material are foreign material, electrochemical corrosion is easily produced, tie point is produced loosening.
In addition, also a kind of technology for connecting sheet material is mechanically deform press-in connection technique, mechanically deform press-in connection work
Skill carries out punching press using special punch-die to attaching plate elements, using metal plastic deformation ability, by embedded between plate
Reach connection purpose.Not only economy, the energy-saving and environmental protection of mechanically deform press-in connection technique, be also highly suitable for being applied to it is heterogeneous it is special-shaped,
Material surface has the connection of the coverings such as coating or paint.Mechanically deform press-in connection single-point static strength be a weld through 70%,
And two point connection can be equal with spot welding, and resistance to vibration is higher than spot welding, and service life is longer than spot welding.But mechanically deform pressure
Power connection there is also it is fatal the shortcomings that.Due to being to reach connection purpose using embedded between plate, therefore must in the side of plate
So a higher projection be present, and opposite side has a corresponding pit.Traditional mechanically deform press-in connection technique due to
There is projection, therefore can not be used requiring the relative occasion slided of plane, limit its popularity used.Further, since
There are pit and projection in both sides respectively, have had a strong impact on its aesthetic measure, it is being had better quality requirement to appearance from using
Occasion.
The content of the invention
In order to overcome disadvantages mentioned above, it is an object of the invention to provide a kind of precompressed hole using soft riveting post to answer with riveting
The sheet material connection method of conjunction, can significantly reduce the height of tie point, and increase the intensity of tie point.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of precompressed hole using soft riveting post and the compound sheet material connection method of riveting, comprise the following steps：
The first step, tie point is produced on upper plate 1 and lower plate 2 using precompressed hole, machine is generated between upper plate 1 and lower plate 2
Tool deforms, and is consequently formed embedded, so that upper plate 1 and lower plate 2 link together, a pit on upper plate 1 be present, in lower plate
A projection on 2 be present,
Second step, the tie point formed after upper plate 1 is connected with lower plate 2 by precompressed hole are tipped upside down on riveting post 5, make riveting post
5 are placed in the pit on upper plate 1, and upper plate 1, lower plate 2 and riveting post 5 are placed between mold 3 and lower mould 4, pass through riveting work
Skill, mold 3 are moved downward, and upper plate 1, lower plate 2 and riveting post 5 are extruded under the cooperation of lower mould 4, are made riveting post 5 that plasticity occur and are become
Shape, it is embedded into upper plate 1, and oppresses upper plate 1 and be further embedded into lower plate 2 at tie point, increases bonding strength, lower plate
The raised height reduction under the pressure effect of mold 3 on 2.
In riveting technique, the material of riveting post 5 outwards flows along around the pit on its upper surface and lower surface, material
Flowing can make in the pit that riveting post 5 is embedded on upper plate 1, and upper plate 1 is further embedded into lower plate 2 at tie point simultaneously
In.
Being shaped as described riveting post 5 is cylindric, and plane is provided with upper pit on cylinder, and cylinder lower plane is provided with lower pit,
Its parameter includes riveting column diameter d3, riveting pillar height degree h, upper pit diameter d2, lower pit diameter d1, upper pit depth l2, lower pit it is deep
Spend l1, upper pit cone angle2, lower pit cone angle1With riveting post fillet R, different companies can be produced by the different combination of above-mentioned parameter
Connect effect.
Described upper plate 1, the material of lower plate 2 are identical.
The material of described riveting post 5 is identical with the material of upper plate 1.
The material of described riveting post 5 is aluminium alloy or copper alloy.
The present invention has advantages below：
(1) traditional rivet needs to do Quenching Treatment, is shaped as the cup shell with sharp tooth, and cost is high.And the present invention makes
Soft riveting post manufacturing process is simple, low cost.
(2) the toothed rivet of tradition has damage to the sheet material of connection, which increase the difficulty of preservative treatment, causes sheet material to exist
The easy corrosion in junction.It is lossless to sheet material and the riveting post full utilization plastic deformation that the present invention uses links together sheet material
Wound.
(3) riveting column material of the invention is and the good material of plasticity such as sheet material identical aluminium alloy, copper alloy, material
It is softer, it is adapted to plastic working, can be with mass production.
(4) riveting post uses identical material with connected sheet material, and it is anti-between riveting post and sheet material electrochemistry will not to occur after riveting
Should, thus the riveting of riveting post it is good after be not present loosening.
(5) using the height that connection point boss can be effectively reduced after riveting post progress riveting, improve tie point outward appearance, make it should
With more extensive.
(6) this method can be effectively increased the intensity of tie point.
