ABSTRACT:
A method and apparatus are disclosed to perform a pair of fabricating operations in sequence on a single workpiece. The apparatus includes an anvil interposed between a pair of spaced, aligned confronting fabricating tools, such as punches or welders. In the apparatus, power means and a force equalization system are mounted on one side of the anvil, so that one of the fabricating tools is essentially at one end of the apparatus. In the method, a workpiece having two generally parallel sections is placed over the anvil such that each workpiece section is interposed between one face of the anvil and a corresponding tool. Then, each workpiece section is subjected in sequence to a fabricating operation, by first displacing one fabricating tool and the anvil toward each other and then displacing the other fabricating tool and the anvil toward each other. During both fabricating steps, the forces applied to the opposed faces of each workpiece section are essentially equalized in order to minimize workpiece distortion.
