    摘要: Grooves are formed in an insertion end of a working tool, such as a tool bit or a chisel bit by pivoting a grooving tool about a pivot axis extending perpendicularly to the axis of the insertion end. By pivoting the grooving tool about the pivot axis, it moves along the axial direction of the insertion end forming the grooves. A plurality of the grooving tools can be ganged together and moved by a single drive unit for simultaneously forming angularly spaced grooves in the insertion end.

    摘要: A CAPTIVE SCREW INCLUDING A SLEEVE HAVING A BORE SUBSTANTIALLY COMPLEMENTARILY RECEIVING A RELATIVELY LARGE DIAMETER PORTION OF THE SHANK OF A SCREW INWARDLY OF THE SCREW HEAD, WITH AN ANNULAR ENLARGEMENT ON THE SHANK, OF GREATER FIAMETER THAN THE BORE, BEING LOCATED AT THE END OF DHIS SHANK PORTION AND RETAINING THE SCREW OT THE SLEEVE. BEYOND THE ANNULAR ENLARGEMENT, THE SHANK IS PROVIDED WITH AN ANNULAR GROVE AND ROLLED THREADS ON ITS OUTER END. THE SLEEVE INCLUDES A HEAD AT ONE END AND AN ENLARGED BOER PORTION AT THE OPPOSITE END PROVIDING A RELATIVELY THIN WALL ADAPTED TO BENT OUTWARDLY TO SECURE THE SLEEVE TO A WORKPIECE. THE FASTENER IS PRODUCED BY FIRST PROVIDING A SCREW BLANK HAVING A HEAD AND PORTIONS OF TWO DIAMETERS, THE LARGER DIAMETER PORTION BEING EXTENDED THROUGH THE SLEEVE, FOLLOWING WHICH DIES ARE ENGAGED WITH THE BLANK AT THE JUNCTURE OF THE SMALLER AND LARGER DIAMETER PORTIONS, PRODUCING AN ANNULAR GROOVE AND DISPLACING MATERIAL OUTWARDLY INTO RECESSES IN THE DIES WHERE THE ANNULAR ENLARGEMENT IS SHAPED. A BULGE ON THE SMALLER DIAMETER PORTION OF THE SHANK ALSO IS CREATED WHEN THE GROOVE IS FORMED, WHICH THEN IS GROUND OFF, AFTER WHICH THREADS ARE ROLLED ON THE END PORTION OF THE SHANK.

    摘要: In a machining method for machining a curved workpiece surface (210) of a workpiece (200), a roll-embossing operation is carried out. At least one rolling element (180A, 180B, 180C) of a machining tool (100) is rolled here under a contact pressure against a section (198) to be machined of the curved workpiece surface. An external surface of the rolling element has a rough surface structure in at least one working section (190A, 190B, 190C) intended for rolling contact with the workpiece surface. The contact pressure is set in such a manner that, during the rolling, a rough roll-embossed structure is produced by local deformation of workpiece material without removing material in the machined region of the workpiece surface. The machining method can be used, for example, for machining the internal surface of a bore in a workpiece, in particular for roughening the workpiece surface for a subsequent coating.

    摘要: A method and apparatus for producing a disc structure. The disc provides a radially extending annular wall formed by pressing a workpiece against a contoured tool with a pressure roll. The contoured tool and workpiece move relative to the pressure roll about a first axis while the tool and pressure roll move toward each other in the direction of the first axis. The pressure roll rotates about a second axis perpendicularly intersecting the first axis and provides a cylindrical working surface. The tooling is arranged to radially confine the workpiece. In one embodiment, the tool is formed with a plurality of ribs extending in the direction of the first axis. These ribs cooperate to produce annular grooves in the workpiece along the surface thereof remote from the pressure roll. One embodiment provides a disc particularly suited for use in electromagnetic clutches. The other embodiment may be used to produce wheels, pulleys, and the like.
