Die Schmiedevorrichtung weist zwei Stauchwerkzeughalter auf, welche die Form von Winkelelementen (7) haben. Diese sind zwischen einem Haupt (1) und einem Untergestell (11) senkrecht zur Richtung des Hubs des Haupts (1) beweglich gelagert und mittels Gelenkhebeln (6) am Kopfstück (1) angelenkt. Die zum Hub des Haupts (1) parallelen Arme (7b) der Winkelelemente (7) sind mit Stauchwerkzeugen (13) ausgerüstet. Zwischen den Stauchwerkzeugen (13) ist ein Werkstückhalter, bestehend aus zwei Backen (2a und 2b), angeordnet. Die senkrecht zur Richtung des Hubs des Haupts (1) angeordneten Arme (7a) der Winkelelemente (7) sind gegenüber dem Backen (2a) des Werkstoffhalters senkrecht zur Hubrichtung des Haupts (1) verschiebbar gelagert.

| 164 | Manufacture of track rod ends | EP80300529.7 | 1980-02-22 | EP0015693A1 | 1980-09-17 | Thompson, Alfred James |
A track rod end having a head portion (12) an a stem portion (14) is initially produced as a drop forged blank such that the length of the stem portion is less than the desired length in the finished article and the diameter of the stem portion (14) is greater than the desired finished diameter. The drop forge blank is then subjected to a hydraulic forming operation which causes elongation of the stem portion (14) to the desired length and reduction of its diameter to the desired diameter. Thereafter, the head (12) may be machined to the desired configuration and the stem portion (14) may be provided with a screwthread by means of the thread rolling technique. This method reduces the amount of material required for the production of a track rod end, the extrusion step and hence the mechanical working of the stem portion (14) increases its tensile strength and the cylindrically formed stem portion (14) created by extrusion facilitates mounting of the track rod end for subsequent machining of the head (12). |
