Document Type and Number:
WIPO Patent Application WO/2018/097376
Kind Code:
A1
Abstract:
The present invention relates to an electric and vacuum molding apparatus for molding an amorphous alloy sheet, wherein the apparatus can operate in the convergence scheme of electrical resistance heating and vacuum molding to mold an amorphous alloy, prevent the leakage of electric currents and gas in the molding process, and ensure molding reliability through uniform application of electricity. The present invention provides an electric and vacuum molding apparatus for molding an amorphous alloy sheet, the apparatus comprising: a molding body including a molding space; a clamping means for holding an amorphous alloy molding sheet located in the upper end of the molding body; a vacuum means for vacuumizing the molding space of the molding body; and a power application means for applying power to the amorphous alloy molding sheet to heat the amorphous alloy molding sheet.
