摘要： A method is for producing a circular cylindrical body (10) comprising a workable mass, having at least one helical internal cavity extending in the interior of the body. The body (10) is initially produced with a straight internal recess, for example by means of extrusion. Afterwards the body is cut to a defined length. The body (10) that has been cut to length is then subjected to a rolling process by means of a friction surface arrangement (23) while being supported over the entire length thereof on a support means (16). The rolling process takes place in multiple steps, wherein a rolling movement using a first axis of rotation (25) is performed in a first step, and a rolling movement using a second axis of rotation (26) that is different from the first axis of rotation is used in a second step. There is also an apparatus for performing the method.

摘要： A self-drilling/self-tapping fastener which is suitable for attaching a sprinkler system to a metal supporting structure has a driving head and an integral shank with a threaded portion. Process-hardening and threading of the shank harden the shank to a degree of hardness that retains sufficient ductility for resisting vibration loads. The drill tip at the end of the shank and the lead threads adjacent the drill tip are locally hardened to a relatively high degree of hardness for drilling and tapping the metal support members. A graduated transition zone separates the high-hardness zone from the lower-hardness zone, which allows for a single fastener to exhibit two distinctly different material properties in one fastener. The fastener through this dual process also exhibits two distinct load-carrying capabilities.

摘要： A threaded fastener particularly designed for extruding and forming threads in a sheet metal material. A threaded shank region and threaded, generally, conical point region are interconnected by a thread forming and extruding region which includes a plurality of partially formed threads both in circumferential extent and depth of impression. The thread-forming region tapers downwardly toward the point region at an angle of about 6.degree. to maximize the thread-forming capabilities of the screw.

摘要： A method and apparatus as disclosed, to produce a work piece, for example -- a twist drill or the same with inside cooling channels by means of a core matrix or core pins incorporated with the deforming pass, instead of using fusable metal filling. The points of the core matrix or core pins are located in the narrow pass of the forming caliber and remain fixed until the work piece is processed. At the end of the forming process, the work piece with its inside, open cooling channels, is expelled and a new operation starts.

摘要： A milling cutter having a shank and a cutting head attached to the shank. The cutting head has a plurality of helical teeth, each tooth including a cutting tip, a leading face and a rear face. A flute is defined between the leading face of a trailing tooth, and a rear face of an immediately preceding tooth. A gully of the flute is generally W-shaped in cross section to provide effective chip evacuation. A method for manufacturing the milling cutter with the W-shaped gully of the flute using a split path grinding process is also disclosed.

摘要： A method for producing a twist drill has the following steps. A blank is shaped to form a semi-finished product. The semi-finished product is formed from a core, coaxial with the drill axis, having a radius and a number of webs, arranged on the core, having a height. The semi-finished product has a constant cross section along the drill axis. The webs have a first portion which adjoins the core and in which a width of the web remains constant or decreases in the circumferential direction with increasing radial distance from the drill axis. The webs have a second portion which adjoins the first portion and in which the width of the web increases in the circumferential direction with increasing radial distance from the drill axis. The webs of the semi-finished product are shaped into helical segments using a plurality of rolling tools that annularly enclose the semi-finished product and roll on the webs along the drill axis. The rolling tools have teeth that are inclined with respect to the drill axis. A height of the helical segments is less than the height the webs. Helical segments formed from adjacent webs are in contact with one another in a closing fold. The invention also relates to a twist drill.

摘要： The screw comprises a circular thread portion 2a formed in a base portion of the screw, in which a helical thread is formed at the same depth and at the same crest angle; a special non-circular thread portion 2b which follows the portion 2a and has its thread depth gradually vary so as to assume a polygonal shape in cross section and permit the crest portion of thread to reach its highest points A-J in a turn of the thread, the highest points A-J being equal in thread depth and crest angle to the thread of the portion 2a; the portion 2b has its crest angle gradually increase as the thread moves from the highest points A-J to its lowest points along the length of the thread; and, lines connecting axially adjacent ones of the highest points A-J are tilted from the axis of the screw at a predetermined angle so that the portion 2b assumes a twisted polygonal prism-like shape as a whole.

摘要： An improved self-tapping or thread-forming screw where the thread configuration on the screw end swages or forms the thread in an object to be threaded rather than cutting and removing a portion of the material of the object. The screw is provided with a threaded shank terminating in a tapered thread-forming end having four equi-spaced flattened surfaces separated by four threaded lobes or corners, and each corner is provided with a leading flattened surface in place of a portion of the radius to provide a partially threaded relief area in addition to the full relief areas formed by the flattened sides.
