Title:
METHOD AND DEVICE FOR PRODUCING SUPERPLASTICALLY FORMABLE COMPONENT
Document Type and Number:
Japanese Patent JPH067857
Kind Code:
A
Abstract:
PURPOSE: To reduce the tendency of the formed cell walls to be undulate and distorted by imbalance of pressure between adjacent cells.
CONSTITUTION: This invention relates to the forming of gas injection/exhaustion manifolds (37, 41) in a superplastic forming process. The manifolds (37, 41) themselves are formed by superplastic forming and allow gas under pressure to be directly applied to (or relieved from) each of the areas (8) which, by the application of the gas will inflate and form cells. The invention reduces the tendency of the formed cell walls to be undulate and distorted by imbalance of pressure between adjacent cells.
