A device for the superplastic forming of a blank, in a mould with a lower and an upper mould, into a component. The blank in the mould can be subjected to pressure and temperature, and the blank has perforations, at least in some regions. The lower mould is formed at least partly with a permeable, in particular a gas permeable, drainage layer. As a consequence of the drainage layer, a blank with perforations can be formed directly, i.e., without further aids such as, e.g., a means of sealing, etc. and/or supplementary production operations, in the course of a superplastic forming process into a component, in particular into a suction component for an active aerodynamic surface of an aircraft, with a complex three-dimensional spatial shape. A simple, cost-effective and reliable process is enabled suitable for large production runs of components, which may be spherically curved in at least some regions. |

1. A device for the superplastic forming of a blank having perforations in at least some regions into a component, in a mould comprising:
a lower mould and an upper mould,wherein for purposes of forming, the blank can be subjected to pressure and temperature in the mould, and,wherein, the lower mould is formed at least partly with a permeable drainage layer, wherein the permeable drainage layer is gas permeable and is connected with a suction unit for gas. |
