SHEET METAL FORMING PROCESS |
摘要 |
A sheet metal forming process and apparatus using both a mechanical forming step and a superplastic forming step. The mechanical forming step includes using a double-action draw die to create a preform. The preform is then transferred to a superplastic forming tool that uses a superplastic forming process to complete the forming process and create a finished workpiece. Using the mechanical forming step enables rapid creation of a preform having a geometry that reduces overall forming time and provides the ability to draw in additional material to reduce part thinning.
