AXIAL CLOSED DIE ROLLING

The Axial Closed Die Rolling Line consists of three machines, viz. A 1600 Ton automatic multi-stage blanking press; a radial ring rolling machine; and an axial closed die finishing press. This is a fully automatic, synchronized and continuous line, controlled by a centralized control panel. The cut pieces are upset and blanked in the 1600 Ton press and transferred to the ring rolling machine, where the inside diameter and outside diameter are expanded to pre-determined shape. The piece is then transferred to the axial closed die rolling machine, where it is finished to near-net shape.

Axial die-rolling takes place in a partially closed die. The significant feature of the process is the conical upper tool. It rotates about an axis which is slightly inclined against the vertical. The bottom die rotates about a vertical axis. Rolling occurs as the upper tool moves towards the bottom die along a path perpendicular to the face of the bottom die. Incremental forming results from this interaction between tooling and forging

ADVANTAGES OF AXIAL CLOSED-DIE FORGING

• Material Saving
• Excellent surface quality
• Near-net close tolerances and less machining allowances
• Superior grain flow so higher strength
• No draft angles, No Flashes, No Mismatch
