9) in the step 2, the material of cavity plate, punch-pin and guiding module is superhigh temperature resistant die steel material, groove, boss
Top and bottom are processed using milling machine, and surface carries out rubbing down processing, make smooth surface.
10) in the step 3, corresponding pickling is carried out before plate assembly and removes oxide film dissolving, is cleaned and is done with ultrasonic acetone
It is dry smooth to keep part to wait for that joint face cleans；With dehydrated alcohol cleaning mold to guarantee that contacting surface waiting does not have impurity, in mold
Corresponding only solder flux is coated with the contacting surface waiting of part；It is transition assembly between cavity plate, punch-pin and guiding module, keeps mold position
It moves direction to fix, completes whole assembly.
11) in the step 5, in hot forming and connection procedure: vacuum degree must reach 10 before heating-3Pa or more rises
Warm rate is 1500 DEG C/h, and it is 60mm/h, heat-insulation pressure keeping time 1h that pressure head, which pushes speed,；The furnace cooling time is 10~14h.
12) a kind of integrated method of joint forming of dissimilar metal laminate provided by the invention is in vacuum high-temperature high pressure
Under the conditions of, make to connection surface forming that bends with profiling mold clamping, and act on hair by the temperature and pressure of certain time
Raw diffusion and realize metallurgy connection, in conjunction with the guiding role of positioning and position-limiting action and guiding module between punch and matrix, realize
The forming and connection of object construction can make connection and forming integrated progress in this way, guarantee effective bonding strength
The bending forming of part is realized simultaneously.
