Claim:
An adjusting device for adjusting the length of a blank segmented from a rod-like material fed to a forging machine, comprising: a support ( 3 ); a cutter ( 4 ) mounted on said support ( 3 ); an adjustment seat ( 51 ) disposed movably on said support ( 3 ); a stop member ( 521 ) fixed to said adjustment seat proximate to said cutter and adapted to stop and abut against an end of the material so that the length of the blank is limited to a distance between said stop member and said cutter; a drive unit mounted on said support to move said adjustment seat so as to change the position of said stop member relative to the cutter for adjustment of the length of the blank; and at least one fluid pressure-operated fixing unit associated with said adjustment seat, said fixing unit being capable of immobilizing said adjustment seat by abutting against said support when said fixing unit is pressurized, or permitting said adjustment seat to move relative to said support when said fixing unit is de-pressurized.
