摘要： An expansion tool includes a housing, a collar rotatably coupled to the housing, a plurality of jaws coupled for co-rotation with the collar, a mandrel movable relative to the housing between a retracted position and an extended position to expand the jaws, and a drive mechanism including a rotatable cam. Rotation of the cam moves the mandrel between the retracted position and the extended position. The expansion tool further includes an indexing gear configured to incrementally receive torque from the drive mechanism such that continuous rotation of the drive mechanism incrementally rotates the indexing gear, and a clutch assembly including a clutch gear meshed with the indexing gear, a clutch cover surrounding the clutch gear, and a plurality of rolling elements disposed between the clutch gear and the clutch cover. The clutch cover is drivably coupled to the collar such that rotation of the clutch cover rotates the collar.

摘要： A machine and method for roller swaging hydraulic fitting sleeves onto metallic tubing comprises a tapered roller mandrel expander driven at a first high speed for rapidly expanding the tubing and at a second low speed until the drive torque reaches a final preselected value for preventing springback of the tubing and accurately controlling the amount of swaging. Both torque control of swaging and diameter control of swaging can be effected. A torque transducer monitors mandrel loading for automatic control of machine operations. A mechanical stop for interaction with the mandrel support regulates advance of the mandrel and thereby relates to diameter control. The diameter control is effected by torque measurements which are responsive to diameter positions. Low speed burnishing can be effected during diameter control at the end of the cycle. The machine provides an automatic swaging cycle with an optimum overall time cycle for swaging performance.

摘要： A method of assembling tubular heat exchangers and particularly of expanding tubes in the tube walls of various heat exchangers and steam generators in the petrochemical, gas-processing, chemical, power, metallurgical and shipbuilding industries including the manufacture of nuclear power plants for ships, of nuclear power stations and related products. According to the method the measuring of a force parameter or variable is effected simultaneously with the measuring of a linear parameter or variable of the expanding successively at three areas, viz. the area of elastic deformation of the tube, the area of plastic deformation of the tube up to the engagement of the tube with the surface of the opening in the tube wall, and the area of elastic deformation of the tube wall.

摘要： Apparatus for assembling tubular heat exchangers and particularly for expanding tubes in the tube sheets of various heat exchangers and steam generators in the petrochemical, gas-processing, chemical, power, metallurgical and shipbuilding industries including the manufacture of nuclear power plants for ships, of nuclear power stations and related products. A rolling tool acts to expand the tubes and measurement of a force parameter or variable is effected simultaneously with the measuring of a linear parameter or variable of the expanding successively at three areas, viz. the area of elastic deformation of the tube, the area of plastic deformation of the tube up to the engagement of the tube with the surface of the opening in the tube sheet, and the area of elastic deformation of the tube wall. Intermediate the tool and its drive is a device for measuring the linear variables of the expanding, and a device for measuring the force variable, the devices being operatively connected with an input of a computer whose output is connected through a control unit with the drive, for selective deenergization and reversing of this drive.
