The invention belongs to the technical field of metallurgy equipment, in particular to a steel wire winding type hydrostatic extrusion machine and an extrusion method. The hydrostatic extrusion machine comprises a pre-stress rack, a die base, a die, a blank, an extrusion cylinder, a return stroke plunger cylinder, a main plunger, a main cylinder and an extrusion cylinder moving cylinder. The pre-stress rack comprises a front beam, a stand column and a rear beam, and the front beam, the outside of the stand column and the outside of the rear beam are all wound with steel wires. The problem thatin the prior art, medium-sized and large hydrostatic extrusion machines do not exist in China, and accordingly development of related industries in China is influenced is solved. The extrusion machine of the structure is compact in structure, large in rigidity and low in cost.
