Embodiments of a crimping device for crimping a radially expandable and compressible prosthetic valve are disclosed. A crimping device can comprise a housing configured to receive a prosthetic valve in a radially expanded state. The housing member can include a funnel segment and an outlet in communication with the funnel segment. The crimping device can further comprise an actuator rotatably coupled to the housing, wherein rotation of the actuator relative to the housing causes the prosthetic valve to move axially through the funnel segment such that at least a portion of the prosthetic valve compresses radially by engagement with the funnel segment and exits the crimping device via the outlet.

A press device comprising a press ring for pressing together tubular workpieces in between, and at least a first and a second pivotable jaw is described. The jaws comprise engagement sections. The press ring comprises receiving sections for receiving the engagement sections of the press jaws. A first and a second surface of the receiving sections, contact the engagement sections. Each of the first and second surface comprises a planar surface. The engagement sections comprise contact surfaces. The contact surfaces oppose each other for applying a press force F. The contact surfaces each comprise at least one convex surface, such that a radius of curvature r of the first and the second contact surface is larger than half a width Wx, Wz, measured perpendicular to an axis of curvature, of the respective first and second contact surface.

The invention relates to a plug assembly (1), in particular for use in a vehicle, comprising a tube (3), a sealing element (5) and a plug connector (4), which comprises a connector body (6), wherein the connector body (6) has an annulus (22) located between a first casing section (12) and a second casing section (15) of the plug connector (4), wherein a connection section (33) of the tube (3) is introduced into the annulus (22) of the connector body (6) and the sealing element (5) is arranged between the first casing section (12) and the connection section (33) of the tube (3). The first casing section (12) of the connector body (6) is deformed in such a way that an interlocking connection is established between a shaping region (56) of the first casing section (12) of the connector body (6) and the tube (3), wherein the sealing element (5) protrudes at least partially into the shaping region (56) of the first casing section (12), such that the sealing element (5) is clamped at least sectionally between the first casing section (12) and the tube (3).

A pressing machine is described for plastically deforming a tubular workpiece, in particular a fitting. The pressing machine has a motor, and pressing jaws which are driven by the motor and can apply a force to the workpiece during operation. The pressing machine also has a power transmission unit coupled to the motor and the pressing jaws for transmitting power from the motor to the pressing jaws. The pressing machine also has at least one sensor unit for measuring at least one pressing parameter P and a controller which receives the currently measured value of the pressing parameter P from the sensor unit and determines therewith the pitch or slope of a press parameter curve K of the press parameter P. The controller terminates a pressing operation before reaching a maximum possible pressing force Pmax when the pitch or slope of the press parameter curve K of the press parameter P satisfies a shutdown criterion. Also described is a corresponding method for operating a pressing machine.

This coupling device for a tubular member is provided with: a base stand for holding an inner member and an outer member in a state in which the outer member is disposed around the inner member; a plurality of pressing members that are supported by the base stand in a movable manner in the radial direction of the inner member and the outer member and have a protruding part on the tip thereof; a pressing member that make contact with the final end of the pressing member and that can press the pressing member radially inward; and a drive mechanism that drives any one among the base stand and the pressing member in a direction perpendicular to the movement direction of the pressing member so that the one member moves relative to the other. The inner member and the outer member are caulked and coupled by driving, by the drive mechanism, any one among the base stand and the pressing member and displacing the pressing member radially inward to thereby expand, radially inward, a portion of a peripheral wall of the outer member by the protruding part.

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.

The invention relates to a method for connecting a connection section (33) of a hose (3) with a plug-in connector (4). The plug-in connector (4) comprises a connector body (6), which connector body (6) has a ring space (22). In a first method step, the connection section (33) is pushed into the ring space (22) of the plug-in connector (4) of the hose (3) from the hose accommodation side (25) of the connector body (6), and positioned there; in a second method step, a pressing tool (50) deforms the first mantle section (12) of the connector body (6). The second mantle section (15) has a narrowing (39) at a front edge (38) of the hose accommodation side (25), whereby it is ensured that the connection section (33) of the hose (3) is freely deformed in the direction of the second mantle section (15) during the pressing process, at least in the region of the ring space (22) that is at a distance from the front edge (38), before the connection section (33) of the hose (3) comes to lie against the second mantle section (15).

Embodiments of the present disclosure provide an axial swage tool configured to axially swage a fitting to a tube, a cable, or other such item of manufacture. The swage tool can be configured to utilize swaging engagement members for grasping and driving a swaging ring over a fitting. The swaging ring thereby radially compresses the fitting around the tube or other item.

Tools for operating on an object, such as a wire or cable are provided. The tool includes a housing and a working head assembly. The working head assembly has a movable section and fixed section secured to the housing. The movable section has a first end movably secured to a first end of the fixed section. The movable section has a second end that is releasably secured to a second end of the fixed section using a latch pin. The working head assembly also includes a latch pin stop that is positioned in the second end of the movable section. The latch pin stop is configured to prevent the latch pin from releasably securing the movable section to the fixed section until the movable section is properly aligned with the fixed section.

Hydraulic crimp tools, working heads for hydraulic crimp tools and die sets for crimping wire connectors onto electrical conductor wires using such hydraulic crimp tools are provided. The die sets include identical dies that can be repositioned on the working head to mechanically secure wire connectors to an electrical conductor wire or a bundle of electrical conductor wires from different orientations.
