PROBLEM TO BE SOLVED: To provide a forging press provided with a mechanism capable of freely adjusting a knock-out stroke even if it is the forging press for executing high-speed forging. SOLUTION: The forging press P has an upper cam 21, which is provided on an eccentric shaft 14, and an upper cam lever 22, which is oscillated following the upper cam 21. It is provided with a knock-out device for ascending/descending a knock-out pin 23 corresponding to the oscillation of the upper cam lever 22. A plurality of the upper cams 21 are provided along in the axial direction of the eccentric shaft 14. The upper cam lever 22 is provided with a switching mechanism 32 for switching a cam roller 31, which comes into contact with a plurality of the upper cams 21 individually, and the upper cam 21 with which the cam roller 31 comes into contact. Even if the high-speed forging is executed, the knock-out stroke can be adjusted. Accordingly, the knock-out pin 23 can be made to follow the upper cam lever 22. COPYRIGHT: (C)2005,JPO&NCIPI
