Abstract
The present invention provides an apparatus for manufacturing a truss structure using multi-point pins, a method of manufacturing a truss structure using the apparatus, a truss core sandwich panel having the truss structure, and a method of manufacturing the truss core sandwich panel. The apparatus includes a metal plate, clamps, an upper die and a lower die. The clamps hold the metal plate. The upper die has upper multi-point pins which press the metal plate downwards. The lower die has lower multi-point pins which press the metal plate upwards. The metal plate has first and second points that respectively correspond to the upper and lower multi-point pins. The first points are extended downwards by the upper multi-point pins, and the second points are extended upwards by the lower multi-point pins. Thereby, many symmetrical sides are formed in the truss structure, thus increasing the stability of the truss structure.
