Abstract
1320748 Stamping AVCO CORP 8 Dec 1970 58241/70 Heading B3Q Aircraft wing-skins &c. 17 prestressed into convex form are shaped by low-velocity impact of metal balls 15 as the skin sheet is advanced relatively to the impact zone. Steel balls as small as # inch diameter, or “ inch or more in diameter fall from one or more shoots 14 which are adjustable vertically and the bases 20 of which are adjustable angularly. The shoot assembly may be movable along the skin 17, or the skin may be mounted on a carriage and pre-stressed over arcuate formers 31. Used balls are returned to the shoots by an elevator 12 outside a rubber curtain 18. Ball-velocities of 15 feet per second and less are referred to and the forming of aluminium, magnesium, steel and clad metals. Masking material may be used for selective forming.
