A capped fastener is provided with two outer flanges and a groove therebetween. The cap is crimped around the first outer flange without covering the second outer flange. The end of the cap is crimped in a groove between the first and second outer flanges. A crimping tool and method of crimping are also provided for crimping the end of a cap into a groove between two outer flanges.

A working head for a hydraulic power tool. The working head includes a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head is configured to receive a first moveable die comprising a first body length and a second die head is adapted to receive a second die comprising a second body length. At least one of the moveable die or the stationary die comprises an elongated die.

A radial press is provided having a main structure, a plurality of pressing jaws arranged around a pressing axis, and having a drive unit which acts on the pressing jaws. The drive unit is supported on the main structure and can move the pressing jaws radially in the direction of the pressing axis and away from the same, at least one fibrous structure is provided radially outside the pressing jaws, the fibrous structure enclosing the pressing jaws and extending in annularly closed form around the pressing axis in a plane which is substantially perpendicular to the pressing axis.

Die sets for crimping busses to electrical connectors are provided. The die set includes a pair of dies where one die has a guide member for aligning the dies with the electrical connector, and the other die has a one or more indentors for impacting the electrical connector. The electrical connectors include a guide hole that receives the guide member.

A radial compression mechanism utilizes a string wrapped around a plurality of compression dies to move the dies inward and close a central cylindrical cavity defined by the working surfaces of the dies. The string may be coupled to a string tension mechanism that enables a user to applied a desired tension to the string and thereby compress an article within the central cylindrical cavity. The compression dies may be coupled to a base and move along die-guiding slots from an open position to a closed position. A spring may be configured to force the compression dies open and provide some back-tension to the string. The string may extend around a pully on an opposing side of the compression mechanism and both ends of the string may be coupled to the string tension mechanism.

An assembly configured to be press joined with a pipe by a pressing tool includes a piping component, which includes a body, a first end having a rim and an inner surface having a plurality of grooves, and a sealing recess wall positioned between the first end and the body and defining a sealing recess. The assembly also includes a sealing element received within the sealing recess of the piping component and having a sealing element thickness. The sealing element thickness of the sealing element is about equal to and not less than a Minimum Sealing Element Thickness Value of the sealing element.

Techniques for implementing and/or operating a system that includes a pipe fitting and a swage machine. The swage machine includes a grab plate having a grab tab that matingly interlocks with a grab notch on the pipe fitting to facilitate securing the swage machine to the pipe fitting and a die plate having a die seat that enables a set of die segments to be used to conformally deform the pipe fitting around the tubing of the pipe segment to be loaded in the swage machine. The die plate and the grab plate include a base plate section, a hinge plate secured to the base plate section via a hinge fastener such that the hinge plate directly abuts the base plate section, and a pivotable plate section secured to the hinge plate via a hinge fastener such that the hinge plate directly abuts the pivotable plate section.

Techniques for implementing and/or operating a system that includes a swage machine and a pipe fitting to be secured to a pipe segment. The pipe fitting includes a fitting jacket to be conformally deformed around tubing of the pipe segment. The swage machine includes a grab plate that interlocks with the pipe fitting; a die seat implemented in a die plate of the swage machine; a die set loaded in the die seat, in which the die set is to be passed over the fitting jacket of the pipe fitting to facilitate conformally deforming the fitting jacket; another die seat implemented farther from the grab plate than the die seat; and another die set loaded in the other die seat, in which the other die set is to be passed over the fitting jacket of the pipe fitting to facilitate conformally deforming the fitting jacket.

A crimping tool with a housing, a motor, a switch connected to the motor for activating the motor, a pump driven by the motor, a piston driven by the pump, an indenter operably connected to the piston, and a tool head connected to the housing, wherein a workpiece can be disposed between the tool head and the indenter. A current sensor is connected to the motor for sensing current flowing through the motor. A processor receives current data from the current sensor, the processor analyzing the current data to determine completion of a crimping operation and/or an error condition. A display connected to the processor can indicate completion of a crimping operation and/or an error condition.

A method for making an air spring assembly, including the steps of providing a bellow, a support ring, and a guide tube. The support ring is positioned relative to a bellow adapter such that a portion of the bellow adapter extends through the support ring. The bellow is then positioned such that a portion of the bellow extends over the support ring and a portion of the bellow adapter. The guide tube is then positioned relative to the bellow and the support ring, such that a portion of the bellow extends into the guide tube and the guide tube is supported by the bellow adapter, and a portion of the guide tube is supported by a ridge support fixture. The first clamp and second clamp are then moved towards the guide tube, applying force to the guide tube, simultaneously forming a first crimp and a second crimp.
