Abstract:
1. An apparatus for roller swaging, the apparatus comprising: a support arm having a radial component and an axial component; a spherical roller attached to an end of the axial component of the support arm for relative rotational movement; a mount slidably supporting the radial component of the support arm for movement of the radial component and the axial component in a radial direction relative to a central axis of rotation of the mount; a first actuator mounted on the mount for displacing the radial component and the axial component of the support arm relative to the mount; a linear slide; a second actuator mounted on the linear slide, the second actuator having an axle that supports the mount and imparts rotational movement to the mount about the central axis of rotation in which the spherical roller describes a circular path; a third actuator connected to the second actuator such that the third actuator displaces the second actuator in a linear direction on the linear slide; and a control connected to activate the third actuator to displace the second actuator along the linear slide to move the support arm into an end of a tube, the second actuator to rotate the mount, causing the support arm to describe a circular path, and the first actuator to cause the support arm to travel in a radial direction outwardly from the central axis of rotation to bring the spherical roller into contact with the tube to form an annular bulge in the tube.
