    摘要： To provide methods, apparatuses and drawing mandrels in which the shaping process can be monitored as closely as possible, a drawing machine and a drawing method manufactures or processes tubes, which extend in the direction of longitudinal extent, from a semi-manufactured product, wherein the drawing machine includes a drawing device for drawing a hollow workpiece formed by the tube and the semi-manufactured product in the direction of longitudinal extent, a drawing ring and a drawing mandrel and acts on the workpiece in a shaping manner via the drawing mandrel and the drawing ring while the workpiece is drawn by the drawing device around the drawing mandrel and through the drawing ring. A sensor is located on the drawing mandrel, or physical properties are measured in the interior of the workpiece and/or on the drawing mandrel using a sensor on the drawing mandrel.

    摘要： Provided is a thin, narrow tube for use in a biodegradable medical device formed from a round tube made of a magnesium material as the base material, in which a desired outer diameter and an inner diameter are provided with good precision over the entire region in a longitudinal direction and a circumferential direction, and the length of biodegradation time can be controlled without changing a material composition. The thin, narrow tube is a thin, narrow tube of a biodegradable medical device, in which the thin, narrow tube is a round tube made of crystals containing magnesium (Mg) having a hexagonal crystal structure, and when the crystals forming the round tube are viewed in a round tube axis direction of the round tube, a hexagonal basal plane (0001) is oriented at a predetermined inclination angle with respect to a circumferential direction perpendicular to a radial direction (a direction from an inner surface to an outer surface) of the round tube.

    摘要： A support structure may include a metallic tube having two opposing ends. The first end may have a first length, a first wall thickness, and a first outer diameter. The second end may have a second length, a second wall thickness, and a second outer diameter. A transition area may be disposed between the first length and the second length. The first wall thickness may be greater than the second wall thickness thereby providing variable thickness.

    摘要： A method for forming a lightweight axle shaft is provided. A first tubular blank is inserted in a die defining an extrusion throat at one end. A tool is inserted into the die having a mandrel with portions of increasing diameter. The tool is moved towards the outlet end of the die to partially extrude the blank through the extrusion throat and form a hollow axle shaft having a variable inner diameter based on the varying diameter of the mandrel. The tool is then removed and a second tubular blank is inserted and placed in engagement with the first blank. The tool, or a different tool, is inserted into the die and again moved towards the outlet end of the die to complete extrusion of the first blank and produce a shaft having diameters at each end that are less than the diameter of an intermediate portion of the shaft.
