Description
Technical field
The invention belongs to sheet material interconnection technique field, and in particular to sheet material of the center with raised varus formula rivet is flat
Sleeving and riveting Joining Technology.
Background technology
There is great number of issues in traditional sheet material connected mode, but sleeving and riveting is connected to connection procedure when connecting aluminum alloy plate materials
Middle rivet can also penetrate upper plate, and upper plate is caused to damage, and be brought inconvenience to sealing and anti-corrosion.In addition, sleeving and riveting tie point is another
Also be present a projection in side, have a strong impact on attractive in appearance.
In recent years again it is proposed that the technique of flat no riveting connection.But this traditional flat no riveting connected mode is deposited again
In following shortcoming：The material of the flat no riveting connection of tradition is flowed up under punch-pin, and punch-pin is big to its frictional resistance,
Easily form the damage even crackle of internal material；The flowing of the flat no riveting connection of tradition is unidirectional backward extrusion mode, flowing
When resistance it is big, the extraneous load needed during shaping is big, and shaping difficulty is big；Bonding strength is lower than sleeving and riveting bonding strength.
The content of the invention
The shortcomings that in order to overcome above-mentioned prior art, it is an object of the invention to provide center with raised varus formula riveting
It the flat sleeving and riveting Joining Technology of sheet material of nail, can be used for the sheet material for connecting heterogeneous material, be effectively increased the intensity of tie point.
To achieve these goals, the technical solution adopted by the present invention is：
Sheet material flat sleeving and riveting Joining Technology of the center with raised varus formula rivet, comprises the following steps：
Before flat sleeving and riveting connection starts, upper plate 4 and lower plate 5 are pressed on lower mould 6 with blank holder 3, lower mould 6
Upper surface flat smooth, the center of blank holder 3 are provided with rivet 2, and the upper end of rivet 2 contacts with drift 1, the central shaft of drift 1 and riveting
The center overlapping of axles of nail 2；
After flat sleeving and riveting connection starts, rivet 2 is pressed into upper plate 4 by drift 1, and plate 4 and lower plate 5 occurs
Deformation, due to being pushed down by blank holder 3, the material of plate can not outwards flow, and upper plate 4 and lower plate 5 are in deformation process, plate
The material of material will flow into rivet 2, and the material flowing of lower plate 5 can squeeze into the material of upper plate 4 in rivet 2, so that
Raise up to be formed in an interior salient point 8 and embedded upper plate 4 among lower plate 5, a mechanical lock formed between two pieces of plate material,
Plate 4 and lower plate 5 is set to link together, because the surfacing of lower mould 6 is smooth, so the lower surface of lower plate 5 is begun
It is smooth eventually.
The center of described rivet 2 carries a projection 7, and the bottom of rivet 2 is in varus formula, and the parameter of rivet 2 includes riveting
Follow closely diameter a, raised bottom circular diameter b, rivet top cylinder height c, height of projection d, height of rivet e, varus internal diameter f, inside-out
Footpath g, raised oblique angle h, varus oblique angle i and varus height j, different connections can be produced using the various combination of above-mentioned parameter and imitated
Fruit.
The present invention has advantages below：Damage and crackle caused by material internal can effectively be prevented；Material flow resistance is small,
The plastic force needed is low, and forming effect is good；Can connecting material combination it is extensive, the sheet material of heterogeneous material can be connected；Quality of connection
Reliably, the intensity of connection is high；The tie point surfacing of formation is smooth；Flat no riveting connection need not propose upper/lower die centering
High efficiency.
Brief description of the drawings
Fig. 1 is that the flat sleeving and riveting of the present invention starts preceding schematic diagram.
Fig. 2 is the schematic diagram after the flat sleeving and riveting of the present invention terminates.
Fig. 3 is the structural representation of rivet 2 of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
Sheet material flat sleeving and riveting Joining Technology of the center with raised varus formula rivet, comprises the following steps：
Reference picture 1, before flat sleeving and riveting connection starts, upper plate 4 and lower plate 5 are pressed on lower mould 6 with blank holder 3,
The upper surface flat smooth of lower mould 6, the center of blank holder 3 are provided with rivet 2, and the upper end of rivet 2 contacts with drift 1, in drift 1
Mandrel and the center overlapping of axles of rivet 2.
Reference picture 2, after flat sleeving and riveting connection starts, rivet 2 is pressed into upper plate 4 by drift 1, and makes plate 4 with
Plate 5 deforms, and due to being pushed down by blank holder 3, the material of plate can not outwards flow, and upper plate 4 and lower plate 5 are deforming
During, the material of plate will be flowed into rivet 2, and the material of upper plate 4 can be squeezed into rivet 2 by the material flowing of lower plate 5
It is interior, so that raising up to be formed in an interior salient point 8 and embedded upper plate 4 among lower plate 5, one is formed between two pieces of plate material
Individual mechanical lock, plate 4 and lower plate 5 is set to link together, because the surfacing of lower mould 6 is smooth, so lower plate 5
Lower surface is smooth all the time.
Reference picture 3, the center of described rivet 2 carry a projection 7, and the bottom of rivet 2 is in varus formula, the ginseng of rivet 2
Number includes rivet diameter a, raised bottom circular diameter b, rivet top cylinder height c, height of projection d, height of rivet e, varus internal diameter
F, varus external diameter g, raised oblique angle h, varus oblique angle i and varus height j, can be produced using the various combination of above-mentioned parameter different
Connection effect.
