Method of Incrementally Reducing and Stretch Straightening Shaped Metal Components
A drawing unit with a segment reciprocating die for drawing metal segments comprises a tensioning device arranged to advance a shaped specimen through an array of dies that create a shaped orifice with the spacing formed between the dies. These dies segments act under the influence of a powered unit to move in a reciprocating motion that causes the spacings between segments to increase and decrease synchronously thereby shaping the metal segments.
Nut integrated with bracket and method of manufacturing the same
A nut integrated with a bracket and a method of manufacturing the same is provided. The method includes a pre-drawing operation that forms a reference aperture and a processing cross section in the plate material supplied between the punch and the die, forming a beading portion and piercing a center of the beading portion. A forging operation forms a pipe portion having a tube shape and processes an exterior circumferential surface of the pipe portion. A precision forging process adjusts dimensions of the pipe portion formed in the tube shape, forms a protruding end that extends on a tip surface of the pipe portion and compresses the pipe portion to remove residual burrs on a surface. A post-processing operation cuts the processing cross section to a final product shape, and forms a threaded tap on an interior circumferential surface of the pipe portion.

Method of making an axle
A one-piece axle and a method of manufacture. The method may include providing a one-piece axle blank that has a shaft and a flange. The shaft may have a hole that may extend along an axis. The flange may extend radially outward from an end of the shaft. The shaft may be radially forged against a first mandrel to axially elongate the shaft.

Composite manufacturing method with extruding and turning processes
A composite manufacturing method with extruding and turning process for extruding and turning a workpiece includes a clamping step, an isolating step, an extruding step and a turning step. The composite manufacturing method is used for manufacturing a surgical instrument. The clamping step is for positioning a clamping portion of the workpiece by a lathe chuck of the lathe apparatus. The isolating step is for blocking a lathe extruding force via an isolating portion of an extruding apparatus. The extruding step is for extruding a processing end portion of the workpiece by the extruding apparatus and generating the lathe extruding force transmitted toward a clamping portion of the workpiece. The turning step is for turning the processing end portion of the extruded workpiece by a lathe apparatus. The extruding apparatus is disposed on the lathe apparatus.

Method and apparatus for manufacturing spokes
A method and a device are provided for manufacturing spokes from a wire material, in particular for at least partially muscle-powered two-wheeled vehicles. The spokes include a spoke shaft having at least two shaft sections. The shaft sections differ in at least one cross-section. For shaping the cross-sections, the wire material is reshaped at least in sections by means of a shaping tool. The relative position of the wire material relative to the shaping tool is varied in the axial direction during reshaping. For shaping the cross-sections in the two shaft sections the relative position of the wire material relative to the shaping tool is varied by way of different positioning movements.
RADIAL PRESS
A radial press has a plurality of press bodies arranged around a press axis which can be moved radially in relation to the press axis, and a drive unit for shifting the press bodies in the direction of or away from the press axis. The press bodies each have a main jaw and a pressing jaw, which is fixed interchangeably on the main jaw. The main jaws each comprise a radially inwardly arranged pressing-jaw-supporting surface and, adjacent to the latter in the circumferential direction, two side surfaces. The pressing jaws butt against the pressing-jaw-supporting surface of the associated main jaw and have a fixing protrusion, which projects from the abutment surface, enters into a mount provided on the main jaw and interacts with a locking device. Each main jaw has a recess on its supporting surface which extends from the mount and opens out on one of the side surfaces.
Method and device for forging a workpiece in bar form
A description is given of a method and a device for forging a rod-shaped workpiece (5) which is deformed with the aid of forging tools (1, 2, 3, 4) in the sense of a cross-sectional displacement perpendicular to the forging axis (a) and is subjected to an axial advancement and possibly a rotation about the forging axis (a) during the pauses in the engagement of the forging tools (1, 2, 3, 4). In order to achieve an advantageous grain refinement, it is proposed that the workpiece (5) is deformed in the sense of the cross-sectional displacement perpendicular to the forging axis (a) in a bending zone (13) between two central supports (11) by means of the forging tools (1, 2, 3, 4) acting on the workpiece (5) radially in relation to the forging axis (a).
