摘要:
The present invention is a system and method for repairing and/or joining together multiple reels of tubular, for example coiled tubing, using friction stir joining using a combination of a disposable or reusable mandrel to react the loads from friction stir joining, and a system for manipulating the coiled tubing so that friction stir joining may be performed while the coiled tubing is on a reel and/or at a field site. These and other embodiments of the present will become apparent to those skilled in the art from 'a consideration of the following detailed description taken in combination with the accompanying drawings.
摘要:
A manufacturing method of an electric contact is provided, in which joining time between a contact and a metal base is short, and a dent or an impression can be suppressed to be formed on the contact, and manufacturing equipment of the electric contact is provided. A contact and a metal base are superimposed and support by a jig, and a rotational tool, which rotates at a predetermined speed, and advances/retracts to/from the jig, is pressed into a surface, which is not contacted with the contact, of the metal base while being rotated, so that the contact and the metal base are joined by solid state diffusion welding by using frictional heat generated by friction between the rotational tool and the metal base, and then the rotational tool is retracted from the metal base.

Die Erfindung betrifft eine numerisch gesteuerte Werkzeugmaschine (10) mit mindestens fünf angetriebenen Maschinenachsen zur Positionierung und Orientierung eines Werkzeugs (18) der Werkzeugmaschine (10) relativ zu einem durch das Werkzeug (18) zu bearbeitenden Werkstück (16) und einem von einer Steuerung zur Einstellung der Maschinenachsenpositionen und einer gegebenenfalls vorhandenen Steuerung oder Regelung eines Hauptantriebs separaten geschlossenen Regelkreis, welcher einen unabhängig von den Maschinenachsen und dem gegebenenfalls vorhandenen Hauptantrieb betätigbaren Aktuator (24) zum Bewegen des Werkzeugs (18) relativ zu dem Werkstück (16) und einen Sensor (38) zum Erfassen des Istwerts einer bearbeitungsrelevanten Regelgröße umfasst und dazu dient, die Regelgröße durch Betätigung des Aktuators (24) auf einen vorgegebenen Sollwert zu regeln. Die Erfindung betrifft auch ein Verfahren zur Bearbeitung eines Werkstücks (16) mittels eines Werkzeugs (18) einer numerisch gesteuerten Werkzeugmaschine (10).
摘要:
A friction agitation welding apparatus comprises a threaded shaft (46) fixedly connected to a motor shaft, a slide housing (48) in engagement with the threaded shaft (46) for vertical movement, a first drive shaft (58) supported for rotation by but coupled fixedly in axial movement to the slide housing (48) and equipped with a friction agitation welding tool (4), and a second drive shaft (64) fixedly connected to a motor shaft and telescopically supported by but coupled fixedly in relative rotation to the first drive shaft (58), moves to advance the friction agitation welding tool (4) to urge superposed workpiece to be joined. When the second drive shaft (64) is rotated, the first drive shaft (58), and hence the friction agitation welding tool (4), rotates even while the friction agitation welding tool (4) urges the superposed workpieces.
摘要:
The invention relates to a method for welding two work pieces (1, 3) according to the friction stir principle. After the work pieces (1, 3) have been welded, a friction arbour (23) is removed from the joint zone (5) and is lifted (43) and thereby inserted into a sacrificial element (31, 51) either simultaneously or after a forward movement (55) in one of the work pieces (1, 3) has been carried out. The sacrificial element forming a sacrificial area (51) can be formed to one of the work pieces (1, 3) as a component thereof. In a preferred embodiment, the sacrificial element is designed as a separate sacrificial body (31) which is adjacently fixed to at least one of the work pieces (1, 3). According to the inventive method, a round welding can be advantageously produced when two tubes are welded, whereby no outlet hole (60) remains where the friction arbour (23) is withdrawn from the work pieces at the end of the welding. The invention also relates to a device (62) comprising a control device (64). The friction arbour (23) can be removed from the work piece (1, 3) in a controlled manner and by means of said device (62), whereby a feed motion (41) of the friction arbour (23) can be carried out simultaneously.
