Description
Technical field
The invention belongs to sheet material interconnection technique field, and in particular to a kind of the flat of lightweight sheet material is connected into without riveting vibration
Shape dress is put and technique.
Background technology
In recent years, being developed rapidly without riveting Joining Technology for connection automobile board can be applied, is adopted without riveting Joining Technology
Punching press is carried out to attaching plate elements with special convex concave mould, using metal plastic deformation ability, is reached by embedded between plate
Connection purpose.Compared with conventional coupling arrangement, in addition to there is greater advantage at aspects such as economy, energy-saving and environmental protection, also fit very much
There is the connection of the coverings such as coating or paint for heterogeneous special-shaped, material surface.Without rivet interlacement technique be do not need it is any auxiliary
Material is helped to can be realized as the new technology of connection, therefore it turns into one of important method of aluminium alloy sheet connection, at utmost
The process of automotive light weight technology is accelerated, is widely applied in automotive field both domestic and external.Rivet is not needed without riveting connection, it is right
It is significant for lightweight.But there is following shortcoming without riveting plastic joining mode in light weight board：Without riveting
The static strength of tie point is relatively low；A projection higher can be produced in the side of sheet material without riveting connection, have a strong impact on sheet material
The quality of connection, an important indicator of current automobile board connection is exactly its aesthetic measure, and connects convex due to existing without riveting
Starting point, is restricted its application on automobile board；Because the projection at tie point can hinder motion, without riveting connection
Be not suitable for being applied to plate surface having the occasion of relative motion；It is strict right that mold and lower mould of the tradition without riveting connection need
In, once generation skew will have a strong impact on bonding strength.
In order to overcome tradition without riveting connection shortcoming, in recent years again it is proposed that it is flat without riveting connection technique, but this
Kind traditional flat have following shortcoming again without riveting connected mode：The flat controllability without riveting Joining Technology of tradition is poor,
The parameter that can be adjusted is few, and the tie point parameter of formation is more single；The flat material without riveting connection of tradition is upward along punch-pin
Flowing, punch-pin is big to its frictional resistance, easily forms the damage even crackle of internal material；The flat stream without riveting connection of tradition
Dynamic is unidirectional backward extrusion mode, and resistance is big during flowing, and the extraneous load needed during shaping is big, and shaping difficulty is big；Tradition is flat
The flanging loop-shaped of connection is mainly V-arrangement blank holder and round blank holder, and resistance during flowing is big, and blank holder needs during flanging
Plastic force it is big.
Vibration assistant metal plastic forming process, refers in conventional metals plastic forming process, to apply ancillary vibration, with
Improve forming quality, improve the technical process of technological effect.Due to bulk effect and skin effect, relatively conventional plastic deformation into
Shape technique, vibration assistant metal plastic process has that shaping load is small, metal fluidity is good, metal forming ability is high, produces
The advantages of quality is high.
Aided in and the flat document report being combined without riveting connection there is presently no finding to vibrate.
