摘要： The invention relates to method for straightening a workpiece (1) with a longitudinal axis, wherein the workpiece (1) is bent out of a starting position transversely to the longitudinal axis and bent back again. In order to provide advantageous straightening conditions, it is proposed that the workpiece (1), which is held on the end side in mounting heads (6), is bent out by means of the mounting heads (6) in directions changing at least in predetermined angular ranges, and bent back again.

摘要： A method and tool for calibrating an extruded tube for use in a manufacturing operation. According to the method, the tube is stretched while in a clamping tool by approximately 3%. The tool encloses the tube while a stretching mechanism is clamped to opposite longitudinal ends of the tube and applies a stretching force to opposite ends of the tube. The tool includes a clamping mechanism that clamps the tube into a cavity and a stretching mechanism with clamps that are attached to opposite longitudinal ends of the tube to calibrate the tube by longitudinally stretching the tube.

摘要： A method for producing a twisted wire (1) by twisting two wires (2) together. When that portion of the twisted wire (1) extending from one ends (3) of the two wires (2) to a first predetermined position (4) is defined as a one end-side twisted portion (5), and that portion of the twisted wire (1) extending from the first predetermined position (4) to a second predetermined position (6) is defined as an intermediate twisted portion (7), and that portion of the twisted wire (1) extending from the second predetermined position (6) to the other ends (8) of the two wires (2) is defined as an other end-side twisted portion (9), a twisting pitch of the one end-side twisted portion (5) and the other end-side twisted portion (9) is smaller than a twisting pitch of the intermediate twisted portion (7).

摘要： A method of straightening a wire rod of titanium or titanium alloy wherein the rod is hot-straightened to a straight rod at the straightening temperature T and elongation .epsilon. satisfying the expression (1) or (2). The method includes hot rolling a titanium billet of .beta. titanium alloy, (.alpha.+.beta.) titanium alloy or a near .alpha. titanium alloy into a wire rod, winding the hot rolled wire rod into a coil, cold drawing the wire rod, cutting the wire rod to obtain a bent wire rod, heating the bent wire rod to a straightening temperature T while both end portions of the bent wire rod are fixed, applying a predetermined elongation .epsilon. to the wire rod, maintaining a straightening temperature T, hot-straightening the wire in accordance with the expression (2).epsilon.(T-400).gtoreq.400 (1).epsilon.(T-500).gtoreq.200 (2)and cooling the wire rod while applying tension. The method is suitable for preparing a straight rod for use in an engine valve.
