METHOD FOR FORMING SHEET MATERIAL, SHEET MATERIAL FORMING APPARATUS, METHOD FOR DETERMINING FORMING CONDITIONS FOR SHEET MATERIAL FORMING APPARATUS, AND DEVICE FOR DETERMINING FORMING CONDITIONS FOR SHEET MATERIAL FORMING APPARATUS

摘要

Provided are a method for forming sheet material, a sheet material forming apparatus, a method for determining forming conditions for the sheet material forming apparatus, and a device for determining forming conditions for the sheet material forming apparatus that can process sheet material with excellent precision when locally heating and forming the sheet material. This method for forming sheet material includes a pressing step that presses a part of a sheet material (10) being formed, which is loaded with a tensile force in a state where the tensile force load has been applied to the sheet material (10), which is formed from titanium or a titanium alloy, to a metal mold (2) that has a curvature for the molding objective and a heating step for continuously heating or intermittently heating at least the part of the sheet material (10) being formed on a plurality of lines parallel to each other.
