摘要： A device for crimping a radially expandable and collapsible prosthetic valve comprises a crimping loop having a first end portion, a second end portion, and a loop portion extending between the first and second end portions and defining an opening configured to receive the prosthetic valve. The crimping loop is movable between a first state in which the opening has a first diameter and a second state in which the opening has a second diameter smaller than the first diameter such that when the prosthetic valve is positioned within the loop portion, movement of the crimping loop from the first state to the second state is effective to reduce a diameter of the prosthetic valve. A method for crimping a prosthetic valve comprises reducing a diameter of an opening of a crimping loop, thereby radially compressing an at least partially expanded prosthetic valve disposed within the opening.

摘要： The present invention discloses a swaging die holder for the flexible shaft operations. In the preferred embodiment, the swaging die holder comprises of an elliptical die holder slot, a stress relief slot, a radius curve, a recess and an insert. The die holder slot at top of the die holder allows each die holder to mount to the machine. The insert is adapted through the recess at the bottom of each die holder and designed to produce the different output profiles at the end of the flexible shaft. The insert is made of HSS material with cobalt content to achieve optimal life. The insert is further re-grinded or re-sharpened for same or other profile applications of the flexible shaft.

摘要： A radial compression mechanism includes a constraining structure with a cut-out defined by a plurality of bearing surfaces. A plurality of die are carried by the constraining structure and arranged in a circular pattern about a central axis. Each die has a base side positioned in parallel juxtaposition to a corresponding bearing surface and each die is constrained to move reciprocally and linearly along the corresponding bearing surface. Working surfaces of the plurality of die cooperate to form a cavity that is movable between an open position and a closed position. A driving mechanism is coupled to at least one of the plurality of die to drive all of the die in unison between the open position and the closed position.

摘要： 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.

摘要： According to a method for forming an elliptical hollow cylinder, part of the elliptical hollow cylinder is formed into a circular hollow cylindrical shape by spinning. The forming method includes a first forming process for forming the part of the elliptical hollow cylinder into a circular hollow cylindrical shape by using an inside roller, and a second forming process for reducing a diameter of the part formed into the circular hollow cylindrical shape in the first forming process by using an outside roller. According to the forming method, it becomes possible to shorten time required for forming the part of the elliptical hollow cylinder into a circular hollow cylindrical shape by spinning.

摘要： Disclosed herein is a method of manufacturing a container for absorbing fluid shock or mechanical shock. The method includes preparing a raw material pipe, forming a coupling pipe by reducing a diameter of at least one side of the raw material pipe, and forming an inner circumference of the coupling pipe and bending it. Accordingly, a container body and a coupling pipe coupled to at least one side of the container body are integrated together, so that an additional process for coupling the container body with the coupling pipe is not required, and thus the cost of production is reduced.
