摘要： A threading turret assembly (100) includes a plurality of threading heads (50). The threading heads (50) comprise first and second threading rollers (52, 54). The threading head (50) is configured to impart a thread (59) onto a metallic can (10) such that a threaded cap may be screwed onto the can (10) to seal an opening in the can (10). The turret assembly (100) is configured to rotate such that the plurality of threading heads (50) orbit the centerline of rotation about which the turret rotates. The turret is configured to impart a rotation onto the plurality of threading heads (50) as the threading heads (50) orbit the center of rotation.

摘要： The present invention is a lightweight threaded bolt type fastener (12) having a shank (21) with a large diameter portion (22) and small diameter portion (28) connected by a transition portion (26); a thread (29) is roll formed on the small diameter portion (22) and terminates in a run-out section (34) where the thread gradually decreases in root depth and width and with the run-out section being of minimal axial length and being located closely adjacent the transition portion (26) to produce a run-out zone of minimal axial length. A rolling die (46, 46') for forming the thread (29) with minimal thread run-out having ridge segments (57) with tapered end surfaces (64) for providing the run-out thread with an end wall (35) parallel to the transition (26) portion and a method of making the bolt type fastener.

摘要： A thread rolling attachment (50) is adapted to be mounted on a machine tool and to be selectively moved in an axially direction relative to a workpiece (W) having a cylindrical surface upon which a thread is to be rolled. The improvement broadly includes a center plate (62) having three circularly-spaced detents (82); a front plate (66) having a central portion (70) arranged in axially-spaced relation to the center plate and having three circularly-spaced lugs (71) extending toward the center plate such that their distal end faces are adapted to engage and bear against a center plate surface (81); a recess (73) extending into each lug from such distal surface, each recess adapted to receive a respective one of the detents for angulary orienting the center and front plates relative to one another; three eccentric roll pins (63) having their opposite marginal end portions journalled on the center and front plates, and spaced equally from one another about an imaginary circle; a thread roll (65) rotatably mounted on each eccentric roll pin; and a plurality of fasteners (68) operatively arranged to selectively hold the center and front plates together; whereby, when the thread rolling attachment is assembled, the front plate will have improved rigidity and will be less susceptible to deformation.

摘要： [PROBLEMS] To provide a method of manufacturing a magnesium-base alloy screw capable of manufacturing, with high productivity, a screw formed of a magnesium-base alloy with excellent strength and the magnesium-base alloy screw. [MEANS FOR SOLVING PROBLEMS] The method comprises a head forging step for manufacturing a screw blank by performing a warm head working to form a screw head part on a wire formed of the magnesium-base alloy obtained by drawing and a rolling step for manufacturing the screw by performing a warm rolling working to form screw threads in the screw blank. In the head forging step, the head working is performed by using a holding die fixing the wire and a punch forming the screw head part, the holding die and the punch are heated, and at least the holding die is heated to a temperature of 140 to 250˚C to heat the wire to a temperature of 140 to less than 250˚C.
