摘要： An internally lubricated, longitudinally split sleeve is positioned on a small diameter portion a mandrel having a rear end connected to a piston with a puller tool. The rear end of the split sleeve is flared and is against the front end of a tubular sleeve stop which immediately surrounds the mandrel. The puller tool includes a tubular sleeve holder which surrounds the sleeve stop. A forward main portion of the sleeve holder is separated by a pair of longitudinal slots into a pair of elongated fingers. The forward ends of the fingers define a sleeve and mandrel receiving end opening and jaws radially outwardly bounding the opening. The mandrel and sleeve holder are both extended and then the puller tool is moved into alignment with a sleeve and is moved endwise to push the mandrel through the sleeve until the flared end of the sleeve is against the sleeve stop. Then the sleeve holder is retracted. Next, the mandrel and sleeve are inserted into a hole in a workpiece and the tool is moved forwardly until the front ends of the jaws are against the workpiece. Then, the puller tool is operated to retract the mandrel through the sleeve and into the sleeve stop. Retraction of the mandrel moves first an increasing diameter portion of the mandrel and then a maximum diameter portion of the mandrel through the sleeve which radially expands the sleeve and cold expands the material immediately surrounding the hole in the workpiece. After the mandrel is retracted into the sleeve stop, the puller tool is moved away from the workpiece. The jaws of the sleeve holder engage and retain the sleeve so that the sleeve is pulled out from the hole in the workpiece.

摘要： A pull gun (10) is used for pulling a mandrel (12, 150, 180) through an expandable sleeve (74, 144, 180) positioned in a fastener hole. The mandrel expands the sleeve as it moves therethrough causing the sleeve to put the metal which surrounds the hole in a state of compression. The pull gun has alternative extensions or sleeve retainers having general appearances of collet chucks and they are adapted to be positioned adjacent holes being prestressed. The retainers are of relatively small diameter for operation through a drill fixture and in small spaces on a workpiece.

摘要： An elongated first tubular member has a mandrel receiving center passageway and a slotted outer end portion that comprises first axial fingers separated by first axial slots. An elongated second tubular member surrounds the first tubular member and has a slotted outer end portion that comprises second axial fingers separated by second axial slots. An elongated third tubular member surrounds the second tubular member and has a slotted outer end portion comprising third axial fingers separated by third axial slots. An elongated mandrel is positioned inside the center passageway. The first tubular member is extendable and retractable longitudinally of the second and third tubular members. A tubular sleeve is provided that has an inner end and a flange projecting radially outwardly from the sleeve at the inner end. The mandrel is extendable axially through the center passageway of the first tubular member and axially through the tubular sleeve when the radial flange is clamped by and between the first and second fingers.
