The present invention relates to a system for manufacturing a frame, using a magnesium panel, through continuous warm rolling pressing, and particularly, to a system comprising: a magnesium panel supply unit, the internal temperature of which is kept at a warm rolling press temperature by means of a heating operation of a heating means, and which heats a plurality of magnesium panels and supplies the heated magnesium panels; a plurality of warm rolling pressing units, each of which has an upper mold and a lower mold formed by arranging a heater, having a constant heating temperature, in a rectangular case, and each of which presses, one or more times, a magnesium panel or a magnesium panel form pressed one or more times in correspondence with the operation of a hydraulic cylinder; a plurality of form heating units, each of which has an upper jig and a lower jig for maintaining the shape of each magnesium panel form, and a chamber, wherein the upper and lower jigs and the chamber are arranged in a rectangular case, and wherein said chamber operates in the upward and downward directions together with the upper jig by means of a hydraulic cylinder, and wherein an internal temperature of the chamber is maintained at a constant level by heating means, and wherein the form heating units are arranged in series after the respective warm rolling pressing units so as to maintain the respective magnesium panel forms at the warm rolling press temperature; a form cooling unit which includes an upper jig and a lower jig for maintaining the shape of each magnesium panel form, a hydraulic cylinder for driving the upper jig, and a cooler, wherein the form cooling unit is arranged after the last warm rolling pressing units so as to maintain, by means of the upper and lower jigs, the shape of the magnesium form which is pressed by the warm rolling pressing units, and compulsorily cool the magnesium form; and a plurality of transfer units which supply the magnesium panels, one by one, from the magnesium panel supply unit to the warm rolling pressing units, or lift by vacuum and transfer the magnesium panel forms pressed one or more times or the finished magnesium forms from the warm rolling pressing units to the form heating units or to the form cooling unit, or from the form heating units to the warm rolling pressing units. The system of the present invention thus enables continuous warm rolling pressing using a magnesium panel, thereby significantly reducing the weight of forms and remarkably improving the strength and hardness thereof. |
