| Abstract: | For the convenience of casting, machining, transporting, etc, the beam of large-scale hydraulic forging press has always been designed as combined structure and connected with pre-stress bolts. According to two different working situations of the hydraulic forging press, the paper carries out the stress analysis of lower beam, then calculates and designs the connecting bolts. |
