    摘要: An apparatus for performing two successive work operations on a workpiece in an equalized force mode. The apparatus includes a base; a yoke mounted for bi-directional movement on the base and carrying a two-sided punch on its upper face; a ram member mounted within the yoke and including two bores opening in opposite faces of the ram member and slidably receiving two pistons secured to the opposite end walls of the yoke; and means for delivering pressurized fluid through the pistons to sealed pressure chambers defined at the inner ends of the pistons between the piston inner ends and the respective confronting faces of the ram to selectively move a pair of die members carried on the upper face of the ram into and out of punching coacting with the double punch carried on the yoke. A force balance system acts to initially move the ram on the yoke in response to the introduction of pressurized fluid to either sealed chamber whereafter, upon engagement of suitable stop means, the pressure fluid acts to move the yoke on the base in a complimentary direction to bring one of the punches into coaction with one of the die members whereafter the pressure fluid is routed to the other sealed chamber and a similar sequence follows to achieve the second punching operation involving the double punch and the other die member.

    摘要: A device and method for severing the piles, grout and structural sleeves of vertical marine structures, from the inside of the structural member or the outside of the structural member. The device will sever the pile, grout or sleeve without jamming even though the weight of the marine structure is bearing down on the pile, grout or sleeve. The device is first lowered into the pile at the desired elevation and further locked onto the wall of the pile. Once the device is locked onto the pile, the cutter is lowered and proceeds to cut into the pile, grout and sleeve. When a sufficient section of the pile, grout or sleeve has been cut, spacers with barbs are forced into the slot formed by the cutter blade and are held in place by the barbs. After the spacers are in place, the remainder of the pile is severed with the cutter blade and a continuity check is made of the pile. An electric probe is placed on the lower section of the pile and if the pile is completely severed, a readout should indicate an open electric circuit. If any portion of the pile is still uncut, the readout should indicate a closed electric circuit. When a closed circuit is indicated, the cutter will rotate and cut the pile where it is uncut.

    摘要: An apparatus for punching openings in tubing (T) includes a stationary mandrel (50) having a guide aperture (142) through the walls thereof and adapted for insertion within the tubing to be punched. A moving actuator (110) having an inclined ramp (130) on one end is receivable within the stationary mandrel. A punch (134) is provided having an inclined end for engagement on the inclined ramp of the moving actuator and an opposite end for engagement through guide aperture (142) in the wall of the stationary mandrel. A T-shaped slot (136) is provided on the inclined end of the punch and a corresponding T-shaped ramp (132) is provided on the inclined ramp of the moving actuator. The engagement of ramp (132) in slot (136) provides for sliding engagement of the punch on the actuator. T-shaped slot (136) and ramp (132) are symmetrical about a plane through the longitudinal axis of the punch and the moving actuator. A stop bar (56) extends to one side of stationary mandrel (50). A plurality of stop arms (66) are hingedly secured to the stop bar for selective engagement against stationary mandrel (50) to act as dimensioning guides. A clamp structutre (60) is supported from stop bar (56) and is selectively movable from a first position circumferentially engaging the tubing mounted on the stationary mandrel and a second position wherein the clamp structure is removed from circumferential engagement of the tubing. Clamp structure (60) has an indentation (154) therein corresponding to the position of punch (134) such that the side wall of the tubing surrounding the area to be punched is supported during the punching operation.
