Definitions
- the invention relates to a method for forming a plate-shaped Component, according to the preamble of claim 1.
- a method for forming a plate-shaped Component is for example from DE-A-3842064 known.
- Shot peening is an alternative manufacturing process for components of this type known in which a component blank in the hardened state largely accurate in contour with relatively low expenditure on production equipment without the mentioned manufacturing difficulties of age creep forming is brought into a spatially curved shape. Disadvantageous is also here, however, that the material properties of the finished Component, namely in particular the residual elasticity, behind the values that are achievable for the selected material.
- the object of the invention is the manufacturing process of the aforementioned Kind so that the mechanical material properties of the formed and hardened component in a simple manner be improved.
- hot aging according to claim 2, the hot curing temperature up to about 12% and the Hot curing time up to about 20% below that for the undeformed material defined values.
- the impact body is formed Component according to claim 3 in a particularly preferred manner during hot aging in a full-surface tool tray with pressurized a mold surface corresponding to the final component contour, so that the deformed component during the by the printing and Influence of temperature during the creep process generated during hot curing is kept dimensionally stable and after the impact body deformation in the component Possibly still remaining inaccuracies and springback leading residual stresses automatically balanced in a simple manner become.
- FIG. Is used to produce a spherically curved base segment described for the tank floors of the fuel tank of a spacecraft. 1, a flat metal plate, e.g. made of a weldable aluminum-copper alloy with a 6% Copper portion, a circular sector-shaped blank 2 produced and accordingly machining the required wall thickness profile of the tank bottom segment processed so that step-shaped thickening 4 increased wall thickness stop.
- a flat metal plate e.g. made of a weldable aluminum-copper alloy with a 6% Copper portion
- a circular sector-shaped blank 2 produced and accordingly machining the required wall thickness profile of the tank bottom segment processed so that step-shaped thickening 4 increased wall thickness stop.
- the component blank 2 is made to that in DE-A-38 42 064 described way, cold-formed by shot peening such that it at least approximately with the spherically curved end contour of the one to be produced Tank bottom segment 6 matches (Fig. 2).
- the component 6 thus formed is then placed in a press tool 8 (FIG. 3), which is a rigid molded shell 10, e.g. made of carbon fiber composite with a spherical curve corresponding to the component end contour Contains molding surface 12.
- a press tool 8 (FIG. 3)
- the component 6 is interposed with an air permeable Absorbent tissue 14 covered by a flexible vacuum film 16, which on the edge by a sealing compound 18 pressure-tight with the molded shell 10 is connected, whereupon the pressing tool 8 with the in the molding space Component 4 enclosed between molded surface 12 and vacuum film 16 an autoclave - not shown - introduced and aged there , the hot curing temperature by about 12% and the hot curing time about 20% below the values for the undeformed material being held.
- the molding space becomes evacuated and the autoclave pressure kept at such a high level that the component material is made to creep.
- component 6 After the end of the hot curing cycle, component 6 is finished and can with other components manufactured in the same way to a hemispherical Tank bottom of a fuel tank for a spacecraft welded together become.
- a circular sector-shaped, flat component blank 2 was produced from the material mentioned above with a radial length of 2500 mm and a width of 2100 mm and was machined to a wall thickness of 1.3 mm with local thickenings up to 4.5 mm brought.
- the component was brought into a biaxially curved shape (radius of curvature R 1 about 3000 mm and radius of curvature R 2 about 2700 mm) by the shot peening.
- the hot aging in the press tool 8 was carried out at an autoclave pressure of 5 bar with a heating rate of 30 ° C./h and a holding time of 14 hours at 160 ° C. All the contour inaccuracies still present were eliminated.
