Abstract:
A method for fabricating a press forming die, comprising the steps of:preparing a die forming prototype and a punch forming prototype; press forming a first blank material with the die forming prototype and the punch forming prototype to obtain a shaped panel; fitting the shaped panel into the punch forming prototype again; placing a second blank material, a resilient sheet and the die forming prototype over the shaped panel fitted to the punch forming prototype in a sequential order; moving the prototype die toward the punch forming prototype relative to one another and stopping the die forming prototype at a position ahead of a bottom dead point of a press forming machine by a given distance for thereby press forming the second blank material with the shaped panel to obtain a die forming panel; and adding a backup material onto a rear surface of the die forming panel to fabricate the press forming die.
