ABSTRACT:
A semi-automatic sheet metal forming machine for forming light gauge metal having a bed formed of a plurality of adjustable and interchangeable spaced spacer plates of various widths, a forming bar having a plurality of removable and interchangeable forming fingers of various widths, and a clamping bar including a plurality of removable slidably mounted clamping fingers of various widths, the clamping bar and forming bar being hydraulically operated and synchronized for semi-automatic repeated forming operations. By adjusting and utilizing different width combinations of the clamping and forming fingers and spacer plates, an operator can perform almost any desired sheet metal forming operation which heretofore would have required separate and expensive special dies.
