I am a student of the Luleå Techniska University (Sweden), and I am actually taking a course called "Sheet
Metal Forming".
Part of the job is to submit a project (about 20pages) about a new sheet metal formability
technique.Therefore, I would be very glad if you could e-mail me some documentation about EXPLOSION
FORMING or give me some adresses where I could find some help.
As far as I understood,this subject appears to be quite new and I am facing difficulties to find
documentation. Thank you for any help you could provide me and I'm looking forward hearing from you.
The Tin Man Respondeth:
Explosive forming is old, probably back in the 1940's it was really refined. Huge capacitors are charged up
for days, then the charge released into a column of water, which divides into H2, exploding, and O2,
which supports the combustion. The charge drives the dieplate into the metal, which is backed by the
reciprocal plate.
Other variations use DuPont DetaSheet explosive, which covers the metal plate to be formed. The metal plate
is then positioned over a die and sealed at the mating edges and the void between them evacuated. A water
column is then filled over the Detasheet for it to lever off of when detonated. Alfred would have loved
the concept.
