Formation method of long shaft type large-inclined-angle flange forging piece

A formation method of a long shaft type large-inclined-angle flange forging piece is used for machining of the long shaft type large-inclined-angle flange forging piece. The forging piece is made of titanium alloy or high-temperature alloy. The method includes preparing a forming die and a tool for the forging piece, preheating the forming die and the tool, placing the forming die and the tool on an anvil face of a forging hammer, placing a lower die of the forming die in an inner cavity of an outer sleeve, taking blank out of a heating furnace and placing the blank in the lower die of the forming die, hammering an upper die through the free forging hammer, enabling the blank to be filled in a die cavity between the upper die and the lower die, and pulling a long rod part to the size of the forging piece. The formation method has the advantages that the used dies are simple to manufacture, low in cost, short in cycle, and particularly suitable for production of the forging pieces in a medium scale or a small
