Abstract
A radial compression mechanism incorporates a plurality of compression die assemblies arranged radially about and forming a central cylindrical cavity. The die assemblies are coupled to a cam plate by a cam bearing retained in cam guide slots in the cam plate. The cam plate is configured to rotate about the central axis of the central cylindrical cavity and thereby rotate the plurality of compression dies about the central axis. The plurality of dies are constrained by a stationary guide slot configured in the housing of the radial compression mechanism and this stationary guide slot forces the compression dies to move radially inward to close the cylindrical cavity. Therefore, the compression dies both rotate about the central cylindrical cavity and move radially inward to close the cylindrical cavity. This arrangement and die displacement mechanism reduces the size or area required by the dies. Therefore the mechanism can be made smaller.
