SUPERPLASTIC FORMING DEVICE FOR CURVED SHAPE, WHICH SUPPLIES PROTECTIVE GAS TO A MATERIAL THROUGH A PROTECTIVE GAS SUPPLY HOLE

摘要

PURPOSE: A superplastic forming device for curved shape is provided to increase the molded product quality of products by measuring the temperature of a mold in a molding process.;CONSTITUTION: A superplastic forming device for curved shape comprises an upper mold(110), a lower mold(120), a heating unit, and a constraining unit. The constraining unit adheres closely the upper mold and lower mold. A protective gas supply hole(H) is formed on the upper mold and lower mold. The protective gas supply hole supplies the protective gas between the molding surface of the upper mold and lower mold and base material. A temperature sensing insertion groove for the temperature sensing is formed on the upper mold or the lower mold.;COPYRIGHT KIPO 2010
