Forging device and forging method of crank throw of marine diesel engine using floating die

摘要

The present invention relates to an apparatus and forging using forged crank throw it with a floating die for marine engines , its object is to form precisely the pin portion of the crank throw by forging, to reduce loss of material, reduce the gas cutting and processing time, improve the work efficiency through this and with a floating die, which can shorten the working time is to provide a method using forged crank throw and forging equipment for marine engines it. The present invention provides installation steps to install a floating block within the bending die and die by the guide arm to the die block located at the bottom of the floating die; Place the pre-bending phase asymmetry and bending die die die blanks on the floating block is installed to pre-bend the upper bending tool; Removing step of removing the die block to remove the die from the bending die and the preliminary bending block; Pressing the upper bending tool in a state wherein the die block is removed by the press bending step, which is to include the final bending.
