Three-Piece Frame
While the former is running, the frame is warped due to the forging load, and the liner is pulled inward. It is important to have a sufficient amount of strength in the stressed area to help counteract this.
For example, for a former with a forging pressure of 21,000kN, a frame weighing more than 150 tons is used to withstand that pressure.
At Sakamura, machining and transportation were taken into consideration to develop a three-piece, highly-rigid frame.
