Pneumatic Booster Assembly Using Continuous Swaging

The swaging process is segmented into multiple sequential operations performed by different rollers. The first roller performs initial swaging, followed by a second roller performing additional swaging at a different location, and potentially a third roller performing final swaging. This segmentation allows the attachment to be strengthened through multiple localized deformation zones without requiring increased material thickness.

The invention implements continuous swaging by sequentially engaging multiple rollers along the periphery of the booster casing. Each roller contributes to the attachment process in sequence, creating a continuous zone of strengthened attachment around the entire periphery rather than relying on discrete spot welds or single-point attachment.

The attachment process is divided into multiple sequential swaging operations by different rollers rather than relying on a single spot swaging operation. Each roller creates a localized swaged region, and the combination of these segmented operations provides comprehensive resistance to wrenching forces around the entire periphery.

Each roller applies swaging force at a specific localized position on the periphery of the booster casing. The first roller swages at one location, the second roller swages at another location, and so on. This local quality approach strengthens specific critical zones without requiring uniform thickening of the entire metal sheet.
