The prior art has a method of supporting the inside of the aluminum profile by inflating an airbag to prevent local deformation of the aluminum alloy profile during the bending process. However, because the surface of the airbag is relatively soft and the inner surface area is large, the conversion of internal pressure to supporting force is slightly insufficient, and many local dents will still occur.

The aluminum profile is decomposed from a long cantilever structure into several shorter cantilever structures through the array-arranged hydraulic support structure, and then the anti-interference performance of the aluminum profile itself is utilized to reduce the incidence of defects caused by stress concentration during bending of the long cantilever structure. Compared with rubber airbags, the surface friction of this structure is low and it is easy to be installed in the aluminum profile. At the same time, it is driven by a cylinder structure, so the driving force is greater and the supporting effect is better. BRIEF DESCRIPTION OF THE DRAWINGS
