C TYPE FRAME STRUCTURAL PRESSING APPARATUS

摘要

PURPOSE: To hold the advantage of a double housing type both frames, too, in a C type frame structural pressing apparatus and to prevent cantilever opening trouble, as the same way as the double housing type frames. ;CONSTITUTION: This pressing apparatus is provided with the C type frame 31 composed of an upper frame 31a, lower frame 31b and center frame 31c, a cylinder 22 for pressurizing at the opening side and a cylinder for balancing in the center frame 31c. The cylinder 31c for balancing generates the force as parallel with the pressurizing force of the cylinder 22 for pressurizing to generate the pressurizing force for cancelling the movement caused by a reaction of the pressurizing force.;COPYRIGHT: (C)1996,JPO
