A three-dimensionally shaped round metallic wire having a cross-section non-circular portion in a predetermined portion without performing additional processing and having specified dimensional accuracy and accuracy of form. In an intermediate step in which the round metallic wire is processed in a predetermined three-dimensional shape, a cross-section non-circular portion forming machine 20 which forms the cross-section non-circular portion having a non-circular cross-sectional shape in at least one position is included. At the time of bending, the cross-section non-circular portion is held by a wire holding portion of a bending machine 30, and the bending is performed in the predetermined three-dimensional shape. Holding the cross-section non-circular portion causes relative rotation between the cross-section non-circular portion and the wire holding portion to be suppressed as compared with a case of the cross-section circular shape. Accordingly, bending accuracy in the three-dimensional shape for the round metallic wire is improved.

Provided is a manufacturing method of a wire rod for forming a coil, the manufacturing method including the steps of: placing an element wire in a forming space surrounded by a plurality of split dies; and pressure-forming the element wire by moving the plurality of split dies in a direction of narrowing the forming space. In the step of pressure-forming the element wire, at least one of the plurality of split dies is moved, and the plurality of split dies each having a surface that changes in shape in a longitudinal direction of an element wire to pressure-form the element wire into the wire rod having a plurality of different cross-sectional shapes in the longitudinal direction.

A method of manufacturing a plate-shaped solder according to the invention of the present application includes an aggregating step of aggregating a plurality of thread solders and a crimping step of crimping the plurality of aggregated thread solders to one another to form a plate-shaped solder. A manufacturing device of a plate-shaped solder according to the invention of the present application includes an aggregating portion for aggregating a plurality of thread solders and a crimping portion for crimping the plurality of thread solders to one another in the aggregating portion to form a plate-shaped solder.

A wire thread insert comprises besides a cylindrical helix consisting of a plurality of coils a moving tang projecting into the interior of the helix for installing the wire thread insert into a receiving thread. The wire thread insert is connected to the cylindrical helix via a bending portion such that the moving tang can be redressed into the receiving thread after installation of the wire thread insert. The wire thread insert is installed by means of an installation tool with a mounting spindle, which installs the wire thread insert in the receiving thread via a moving shoulder and the moving tang. A compression blade provided at the mounting spindle bends the moving tang back into the receiving thread while the mounting spindle is removed from the installed wire thread insert.
