ABSTRACT:
This invention relates to a forming machine which is composed of several types of split dies in an upper die. The length of the upper die is adjusted by changing the combination of the split dies. The upper die assembly has an upper die body mounted on the lower end of a ram. A group of upper split dies are slideably inserted laterally of the die and in the lower portion of the upper die body. A number of upper thin dies are inversely mounted at the center of the upper split die group. A select finger driving mechanism is provided at the front of the upper die body to slide the upper split dies in the lateral direction of the die. An inverting mechanism is provided at the rear of the upper die body to invert the desired number of the upper thin dies and locate them between the split dies to form a die of the desired bending length.
