<p>@ Circumferentially spaced, radially movable die members (56) for crimping are mounted in a die supporting ring (52, 54) positioned radially inward of circumferentially spaced radially movable pusher membres (46) engageable with the die.</p><p>The die supporting ring (52, 54) is removably mounted on a fixed head (14) and the pusher members (46) are urged radially inward by axial movement of a crimping head (22) having sloping surfaces (42) slidably engageable with sloping surfaces (44) of the pusher members (46). The slidable sloping surface (42, 44) of the crimping head (22) and the pusher members (46) may be flat and matched by wear. The engageable surfaces (62, 64) of the die members (56) and pusher members (46) are not slidable and may have a matching configuration which is not affected by wear.</p> |
