Summary:The invention discloses a variable-load forging device, comprising a master cylinder, an assistant cylinder, a main piston, a handspike and a fixing part. The master cylinder is communicated with an internal cavity of the assistant cylinder, and the axial lines are crossed. The insides of the cavities of the master cylinder and the assistant cylinder are filled with liquid. One end of the main piston is arranged in the master cylinder, and the other end is arranged outside the master cylinder and bears the action of outside force. One end of the handspike is arranged in the assistant cylinder and is used as a piston of the assistant cylinder, and the other end is arranged outside the assistant cylinder. The fixing part and the handspike are arranged oppositely. One end of the handspike outside the assistant cylinder and the fixing part are respectively provided with a mould used for forging. The variable-load forging device ensures that the load at the vertical direction of the traditional pressing machine is
