  • Publication number: 20140260504
    Abstract: A portable rescue tool that is powered by an electric motor. The electric motor has a drive output shaft that transfers rotational power to an angle rotary gearbox. The angle rotary gearbox has an output shaft that is oriented about 90 degrees from the rotational axis of the motor output shaft and is geared so as to increase the torque and reduce the speed of the rotational power. The angle rotary gearbox provides a reduced speed, high torque output at an output shaft that is delivered by a single chain drive to a main rotary actuator where two actuator arms are controlled to move away from each other and toward each other in the operation of the rescue tool. The portable rescue tool is designed to be of a low weight and enhanced cooling properties as present rescue tools.

The press head and the base each include features configured to allow respective attachment of a first tool and a second tool, and whose specific configuration depends on the operation being performed by the press (i.e., shaping, assembly requiring pressure, etc.) The press head, when in the first position, is operative via the tie rod to place the base in the load position.

  • Patent number: 5996392
    Abstract: A stamping and bending machine (10) has upper and lower horizontal supports (18, 16) in each of which are formed two longitudinal chambers (80) which open out through broad longitudinal slits (86) on opposite sides of the horizontal supports (16, 18). On both lateral faces of the horizontal supports (16, 18) carriage assemblies (26) are fixed; each of these carries an angular gear (36) which is encapsulated in a gear housing and protrudes through the longitudinal slit (86) into the appropriate longitudinal chamber (80). The angular gears (36) in each longitudinal chamber (80) are provided with coaxial through-channels with polygonal profiles. A drive shaft (28) with matching polygonal profiles is inserted through the angular gear (36) of each longitudinal channel (80) and couples the carriage assemblies (26) together.

  • Patent number: 5916321
    Abstract: A rod driver gear for a tubing expander is operable to drive a rod having a circumferentially extending outer surface with a plurality of grooves extending traversely across a longitudinal axis of the rod. The rod driver gear includes an annular body rotatably mounted to a frame of the tubing expander and connected to a power source of the tubing expander. The annular body has a ridged outer diameter surface. Each ridge of the outer diameter surface is dimensioned to extend into the grooves of the rod to sequentially engage the grooves of the rods when the power source rotates the annular body to thereby move the rod along the longitudinal axis of the rod. In a preferred embodiment, the outer diameter surface of the annular body has a plurality of grooves extending across the surface, and a plurality of pins are inserted through a bore into the grooves. A portion of the pins extends from the grooves to constitute the ridges.

  • Patent number: 5720199
    Abstract: A pressing tool for transforming workpieces includes a first fixed position die for transforming the workpiece. A second die cooperates with the first die in transformation of the workpiece, and the second die is coupled to and movable in response to operation of a forward feed device. The forward feed device comprises a rough feed device for relatively rapidly moving the second die toward the workpiece, and a fine feed gear for relatively slowly moving the second die toward the workpiece. The fine feed gear is coupled to and movable with the rough feed device. The forward feed device causes control over movement of the forward feed device to be shined from the rough feed device to the fine feed gear upon engagement of the second die with the workpiece.
