摘要： A split sleeve (96) is seated in a fastener hole (10) in the web (8) of a rail section (2). The tapered portion (26) of a mandrel (20) is firmly seated in the hole (10) inside the sleeve (96). A puller mechanism jaw (40) and a nosecap (78) are moved downwardly over the projecting rear end portion of the mandrel (20) to position the rear end portion in aligned U-shaped slots (50, 84) in the jaw (40) and nosecap (78). During the downward movement, guide surfaces (72) carried by the jaw (40) guide a chamfer (32) on the mandrel (20) into seating engagement with a tapered surface (56) on the jaw (40). The guide surfaces (72) may be formed by cylindrical pins (70) received into angled openings (58) in the jaw body. The front surface (88) of the nosecap (78) securely abuts the Web (8). With the mandrel ( 20) seated and the nosecap (78) abutting, the jaw (40) is moved rearwardly to pull the mandrel (20) through the hole (10) and cold expand the hole (10).

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.
摘要翻译： 内部润滑的纵向分开的套筒定位在小直径部分上，心轴具有通过拉拔工具连接到活塞的后端。 开口套筒的后端是喇叭形的，并且紧靠着立即围绕心轴的管状套筒止动件的前端。 牵引工具包括围绕套筒止动件的管状套筒保持件。 套筒保持架的前部主要部分由一对纵向狭缝分隔成一对伸长的指状物。 指状物的前端限定了套筒和心轴接收端部开口并且径向向外限定开口。 心轴和套筒保持架都伸出，然后将牵引工具移动成与套筒对准，并使其向后移动以将心轴推过套筒，直到套筒的喇叭形端部抵靠套筒止动件。 然后套筒保持架缩回。 接下来，心轴和套筒插入到工件中的孔中，并且工具向前移动，直到夹爪的前端抵靠工件。 然后，牵引工具被操作以使心轴通过套筒缩回到套筒止动件中。 心轴的回缩首先移动心轴的增加的直径部分，然后通过套筒的心轴的最大直径部分径向扩张套筒，并且冷却使紧邻工件的孔的材料膨胀。 在心轴缩回到套筒止动器之后，拉出工具从工件移开。 套筒保持器的夹爪接合并保持套筒，使得套筒从工件中的孔中拉出。

摘要： An abrasive jet-forming nozzle assembly is disclosed for use in a waterjet cutting system. The nozzle assembly includes a jet-forming orifice for producing a high velocity jet from a highly pressurized water upstream of the orifice, and a discharge tube downstream of the orifice for permitting abrasive particles to become entrained in the jet, and for discharging the abrasive-laden jet against a workpiece. The discharge tube is pivotably movable into alignment with the orifice.
