FORMING METHOD OF METAL ALLOY SHEET WITH LOW FORMABILITY USING INCREMENTAL FORMING PROCESS WITH EXTERNAL HEAT SOURCES

摘要

PURPOSE: A forming method of a low-formability metal alloy sheet using a gradual forming process with an external heat source is provided to form various shapes by increasing the temperature of a material outside and performing a gradual forming process. CONSTITUTION: A forming method of a low-formability metal alloy sheet using a gradual forming process with an external heat source is as follows. A plate-shaped material is located at the top of a mold. The material is pressed using a forming tool(14) and is gradually formed. The temperature of the material is partially increased using an external heat source. The forming tool is located at an accurate position of the material, and the material is formed by moving the mold.
