Hinge beam structure of large cubic press

The invention relates to the technical field of diamond production, and more particularly discloses a hinge beam structure of a large cubic press, which comprises a base, four support plates are fixedly connected to the upper surface of the base, a fixing plate is fixedly connected to the side surface of each support plate, a support block is fixedly connected to the side surface of each fixing plate, and the support blocks are fixedly connected to the upper surface of the base. A supporting groove is formed in the upper surface of the supporting block, a carrying mechanism is arranged in the supporting groove, a fixing mechanism used for fixing objects is arranged on the side face of the supporting block, and a jacking mechanism used for jacking is arranged on the side face of the supporting plate. A power mechanism used for providing power for the jacking and pressing mechanism is arranged on the side face of the supporting plate, by arranging the carrying mechanism, when diamond raw materials need to be ma
