Description
Technical field
The present invention relates to the device and method in a kind of riveting technology field, specifically a kind of towards unimach
(i.e. unimach) rushes glue riveting composite connecting device and method certainly with the sensing heating auxiliary of light metal.
Background technology
In recent years, day by day reducing and the continuous aggravation of environmental pollution, to promote vehicle fuel economy along with petroleum resources
Property and the Vehicle mass reduction that environmental-protecting performance is target become the trend of the times of automobile industry development.The non-ferrous alloy such as magnesium, aluminum
The high-quality important means applying nature to become body lightening than the mixing of material by force such as material and advanced unimach.So
And the non-ferrous alloy material thermal conductivity such as magnesium, aluminum is good, conductivity is high and easy and copper generation alloying reaction, the most above-mentioned non-ferrous alloy
With the fusing point of advanced unimach and thermal expansion coefficient difference is huge and is easily formed hard and crisp intermetallic during melting welding
Thing, therefore, uses traditional resistor spot welding method to be difficult to form effective joint.
For the problems referred to above, abroad propose a kind of METHOD FOR LARGE DEFORMATION ELASTOPLASTIC utilizing material and rivet and workpiece to be connected it
Between formed firm interlock mechanical cold forming process semitubular rivet self-piercing riveting (Self-piercingriveting, letter
Claim SPR).This technique efficiently and effectively avoids because of the input of amount of heat and the series of problems that causes during melting, simultaneously
Its punching, the feature of riveting integration create advantage for quickly producing and realizing high-volume streamline manufacture.But, this company
Connect the joint forming property of technique and comprehensive quality of connection depends on elongation percentage and the intensity of lower plywood mostly, above-mentioned in riveting
When non-ferrous alloy and unimach, this feature is especially prominent.When top plate is advanced unimach, owing to material is strong
Degree high (hot strength of some advanced unimach is even greater than 1000Mpa), after riveting, rivet is easy upset affects joint power
Learning performance, some rivets even crack, and directly result in joint fails；And when lower plywood is unimach, due to riveting
When connecing, the resistance of deformation of material is relatively big, plastic deformation difficulty, on the one hand adds equipment sleeving and riveting ability, riveting gun c-type framework firm
Degree and the requirement of rivet value, add production cost；On the other hand, the advanced ultrahigh-strength steel plates of deformation difficulty makes to connect
Head forming property is poor, directly results in joint quality of connection the highest.
For the problem of semitubular rivet self-piercing riveting, the research worker of Monash university of Australia proposes before riveting
Use LASER HEATING advanced person's unimach sheet material, to improve the plasticity of sheet material, reduce plastic deformation resistance to reduce riveting simultaneously
Relay and raising forming property.But laser heating device is much more expensive, power consumption is very big, and must be at generating laser and steel plate
Between without hindrance, if double-layer plate to be riveted, it is necessary to the most simultaneously arrange two generating lasers, use inconvenience and cost very
High.
Sensing heating is a kind of effective mode of heating, the most commonly used, but only needs in riveting process
To carry out concentrating heating, existing mosquito incense formula load coil volume to the regional area (scope within 10mm) intending riveting
Greatly, and the local in big plane cannot be carried out concentrate heating.
It addition, when heating unimach, heat can pass to the light metal of high heat conductance by the way of conduction of heat,
Cause light metal side resistance of deformation to reduce, thus reduce rivet and insert the expansion deformation of stage rivet, and finally reduce joint
Undercutting amount size and mechanical property.

Answer heating system that unimach to be riveted local is carried out quickly, concentrate heating, heating to terminate rear coil and be quickly moved out, simultaneously
Riveting actuator is moved rapidly into riveting location, and gas-liquid force increasing power unit promotes riveting actuator to being heated to specific temperature
The sheet material to be riveted of degree carries out Quick-rivet.The present invention by the hot depression effect of lower thermal conductivity structure glue and rivet hot process time
When sequence accurately controls to solve advanced unimach riveting, rivet is the most upset, joint undercutting amount is little, unimach easily produces
The problems such as raw crackle, effectively reduce plastic deformation resistance during riveting unimach, and improve joint comprehensively connects matter
Amount, and compared with the means such as LASER HEATING, there is the lowest cost.
