Abstract

The components of a hydroforming machine include a die housing for containing a plurality of dies, a water distribution system, and a means for compressing the dies. The dies includes first and second die plates which are secured together by a key inserted into aligned keyways in each of the first and second die plates. The key is non-rotatable, such as being square shaped, rectangular, triangular, or the like for eliminating interference with adjacently positioned keys. The pins and links coupled to the die plates are held in position by keepers, which are elongated narrow pieces of metal positioned substantially parallel with the die plates and having a width approximately equal to the width of the die plates for allowing a person to view between the adjacent dies and into the die housing for observing formation of the bellows during the hydroforming process.
