Described here are devices and methods for crimping self-expanding devices. The crimping devices may be useful for crimping a variety of different self-expanding devices (whether such devices are biodegradable or bio-durable). The crimping devices may have crimping members to engage the self-expanding device to reduce the device from an expanding configuration to an unexpanded configuration. The crimping member may comprise or include a suture, wire, ribbon, guiding hoop, pusher, prong, holding bar, balloon, jaws, combinations thereof, or the like. The crimping devices may also include or comprise a holding structure to hold the self-expanding device in an unexpanded or expanded configuration.

A tool assembly for forming a workpiece with an outer surface into a housing with a non-round design outer profile. The tool assembly includes a number of jaw segments, each jaw segment having an internal surface for engaging the outer surface. The jaw segments are movable between a first condition and a second condition, in which the internal surfaces of the jaw segments substantially define the design outer profile of the housing. Each internal surface has a preselected end point associated therewith defined by a radius centered on the preselected end point that is substantially coincident with the portion of the design outer profile defined by the internal surface. Each jaw segment is movable toward the preselected end point therefor when moved from the first condition to the second condition, and away from the preselected end point therefor when moved from the second condition to the first condition.

A die for use with a cold-formed joint tool such as a clinching tool or clinch punch or self-piercing rivet punch. A split die made of a plurality of partial cup-shaped segments is disposed within a collar that defines a recess. The recess includes a forming area in which the cold-formed joint is formed and a relieved area in which the partial cup-shaped segments are shifted radially outwardly after forming to permit removal of the cold-formed joint tool from the cold-formed joint.

A device and method for producing a component are provided. The device or method includes steps or units for providing a first component element having a recess in or on a first surface of the first component element, and for positioning a second component element in the region of the recess. The device or method also includes a step or unit for pressing the first component element and the second component element together, and as a result forming a material fit, positive fit and/or non-positive fit between the first and the second component elements at least in the region of the recess. The positioning and the pressing can be carried out or are carried out functionally, in particular, spatially and/or temporally, in terms of equipment, separately from each other.

Sets of apparatus for translating motion from a rotating non-circular loop to linear motion and in possible cases vice versa. Such mechanisms are used in muffler cap spinning technology and engine crankshaft with uneven strokes; but not restricted to said applications. The mechanisms include a non-circular cam, a linear sliding arm or piston and parts to connect them. Disclosure also includes an adjustable closure for a sliding arm which could be utilized for said muffler cap spinning mechanisms or other applications.

A method for crimping a medical implant includes at least one foldable and/or unfoldable structure on or around or over a portion or outer surface of a catheter or of a catheter tip. No pressure beyond a predetermined pressure is exerted on the structure during and/or after crimping of the implant.

A system and method for manufacturing a top mount for a vehicle suspension includes loading a top mount body, a journal, and a plurality of knurled studs into a lower die assembly. The lower die assembly includes a stationary die base, a floating die top, and a pusher shaft. A pusher head assembly applies a downward pressure to insert the knurled studs into the top mount body, while the pusher shaft substantially simultaneously applies an upward pressure to insert the journal into the top mount body. The floating die top and the pusher head assembly are raised in tandem to eject the top mount from the stationary die base. The floating die top and the pusher head assembly then retract so that the top mount can be removed from the system.

A riveting device for setting a blind rivet element includes a mandrel, a first motor comprising a first operative connection to the mandrel, and a second motor comprising a second operative connection to the mandrel. The mandrel is configured to have a rotational movement be transmitted thereto to screw the mandrel into the blind rivet element, and to be retracted into the riveting device by a retraction movement to produce an at least partial plastic deformation of the blind rivet element. The first motor transmits the rotational movement to the mandrel via the first operative connection. The second motor transmits the retraction movement to the mandrel via the second operative connection.
