Abstract

PURPOSE:To make lubrication efficient by pressurizing with the forging blank pushed from the cavity upper part the lubricating oil filled up in the cavity and also discharging it from the cavity lower end with maintaining a fixed pressure. CONSTITUTION:A lubrication oil O is filled up in the cavity 3 of a die device 1 and a forging blank W is pushed in from the upper part of the cavity 3. The lubrication oil O is pressed by the forging blank W and when the pressure of the lubrication oil O exceeds a specified value, a relief valve is opened and the oil O is discharged from a discharging path 7. With this method the lubrication effect is improved and the quality is improved.
