Abstract

PURPOSE:To enable warn and hot forging without giving special consideration to the temp, control of a work by performing the forming in the specified shape by a die after heating and softening the die of a sufficiently heating state by its press-contact to the work of a cold state. CONSTITUTION:A work W is fed as it is in a cold state to the forming chamber 5 of a forming device 1, on the other hand, an upper die 3 and lower die 4, and a main body 2, if necessary, are heated. Then, when the work W is pressurized by a sufficiently heated upper die 3 and lower die 4, it is heated by the temp. of the upper and lower dies 3, 4 and at the time when the work W is ascended to the temp. necessary for its softening, the upper die 3 is approached to the lower die 4 without any special operation and the work W is formed in the specified shape. In such a case as causing the biting of the lower die 4 and work W an operating oil L is fed to a trimming die medium feeding chamber 6 and the work W bitten into the lower die 4 is pulled out by utilizing the oil pressure of the operating oil L.
