Title: Cogging forging method of round bar of material difficult to work
Inventor: ITO JUICHI
IPC: B21J5/00
Filed: 2021-01-28
Abstract: To provide a cogging forging method which performs hot free forging to a round bar with preferable efficiency of manufacture while heating an alloy lump such as forging alloy which is brittle and easy to crack in a furnace.SOLUTION: A cogging forging method performs cogging to a round bar while heating an alloy lump in a furnace. The method comprises a cogging step of holding in a cantilever manner a bar-shaped alloy lump having a center shaft and arranging it over a lower mold, and pushing an upper mold against the alloy lump to perform cogging while rotating the alloy lump around the center shaft in the furnace. The lower mold and the upper mold have upper part gutter-shaped groove and lower part gutter-shaped groove respectively, and are arranged so as to make axial lines to be in parallel to each other and make openings to be opposite to each other. The cogging step uses the lower mold which has the lower part gutter-shaped groove with a vertical cross-section with respect to the axial line as a part of circular arc, and cogs the alloy lump into a diameter smaller than a diameter of the circular arc while giving compression in a radial direction to the alloy lump with an internal face of the lower part gutter-shaped groove.SELECTED DRAWING: Figure 3
