The invention discloses a large railhead precision forging press. The large railhead precision forging press comprises an anti-impact base, a disassembling and assembling platform, a forging and pressing base, side forging and pressing mechanisms, a positioning column, a guide table, a forging and pressing column, a forging and pressing block, a fixed table and an oil tank, wherein the bottom of the disassembling and assembling platform is fixedly connected with the top of the anti-impact base by virtue of a bolt, the bottom of the forging and pressing base is fixedly connected with the top ofthe disassembling and assembling platform, the side forging and pressing mechanisms are arranged on both sides of the forging and pressing base, the guide table is installed on the positioning columnin a lifting mode, the bottom of the forging and pressing column is removably installed on the top of the guide table, the top of the forging and pressing block is removably installed at the bottom of the guide table, and the bottom of the fixed table is connected with the top of the positioning column. According to the large railhead precision forging press, the forging and pressing operation issynchronously performed on multiple surfaces, so that the processing time of excessive forging and pressing can be shortened, the forging and pressing efficiency is improved, and the problems of sputtering and splashing of oxides on side surfaces during falling are avoided when a railhead is extruded to deform.
