Description
DEUTSCHESGERMAN
In neuerer Zeit wird die Verformung λ on Profilen auf sogenannten Streckformmaschinen durchgefühi f, bei denen das Material, be\or es um die Form herum gebogen wird, auf einen vorbestimmten Wert vorgereckt wird, der nahe an der Streckgrenze liegt. Dieses V1On^cjicn^eschient mit Hilfe von hydraulischen Zylindern, die auf beweglichen Schlitten angeordnet sind. Diese Maschinen arbeiten mit einer \ ertikalen Bewegung des Werkzeuges, meist ubei Kolben und Zylinder, und mit einer horizontalen Bewegung der Spannköpfe, in denen das Profil an den Enden gefaßt ist.More recently, the deformation of profiles is carried out on so-called stretch-forming machines, in which the material, before it is bent around the shape, is pre-stretched to a predetermined value that is close to the yield point. This V 1 On ^ cjicn ^ eschient with the help of hydraulic cylinders, which are arranged on movable carriages. These machines work with a vertical movement of the tool, usually with pistons and cylinders, and with a horizontal movement of the clamping heads, in which the profile is gripped at the ends.
Der Vertikalzylinder und die Spannkopflaufbahnen bilden einen T-förmigen Maschinenkörper, wobei der Hub des Kolbens die Grenzen der Verformung bestimmt, tst er sehr groß, so sind tiefe und damit teuere Fundamente notwendig.The vertical cylinder and the clamping head raceways form a T-shaped machine body, the The stroke of the piston determines the limits of the deformation; if it is very large, it is deep and therefore expensive Foundations necessary.
Ferner wird bei großem Veitikalhub die Übersicht über den Arbeitsvorgang sehr erschwert, weil der oberste Punkt des Werkzeuges dabei weit über die Augenhöhe des Werkers hinauswandert.Furthermore, with a large vertical stroke, the overview on the work process is very difficult because the top point of the tool is way above the Wandering out at eye level with the worker.
Diese Nachteile werden durch die Erfindung beseitigt, indem das Maschinengestell liegend ange ordnet ist und der Werkzeughub so groß bemessen ist, daß auch sehr tiefe Verformungen, wie sie beispielsweise bei Flügel- und Leitwerks rippen eines Flugzeuges vorkommen, möglich sind.These disadvantages are eliminated by the invention in that the machine frame is lying is arranged and the tool stroke is dimensioned so large that even very deep deformations, such as those for example in the wing and tail unit ribs of an aircraft are possible.
Das Werkzeug und der Verformungsvorgang ist selbst in weit ausgefahrener Stellung zu beobachten, so daß der Bedienungsinann uneingeschränkt zu den Spannköpfeu gehen und eventuell Profilabrissen vorbeugen kannThe tool and the deformation process is can be observed even in a far extended position, so that the operator can go unrestrictedly to the clamping heads and possibly prevent profile tearing can
Der durch den großen Werkzeughub erreichte Vorteil ist besonders augenfällig, wenn einseitige Verformungen vorgenommen werden, d. h. wenn nur mit einem Spannkopf schlitten gearbeitet wird, während das andere Profilende in einem Spannkopf gefaßt ist, der mit dem Werkzeug fest \ erblinden ist.The advantage achieved by the large tool stroke is particularly noticeable when one-sided deformations be made, d. H. if only one clamping head slide is used while the other end of the profile is held in a clamping head which is firmly blinded with the tool.

stand in die Spannköpfe 13 eingespannt {Fig I) und zunächst mit Hilfe der hydraulischen Zylinder 12 \orgereckt. Hierauf fährt der Schlitten 2 mit dem Formklotz 3 gegen das Werkstück 14, das sich beim weiteren Vorschub des Schlittens 2 tangential an den Formklotz 3 anlegt. Gleichzeitig laufen die Schlitten 8 auf dem Querteil 7 des Maschinenbettes nach der Mitte hin nach. Dieses Nachlaufen wird durch Elektromotor e bewirkt, deren Steuerung in Abhängigkeit \on der Profilspannung mit bekannten Mitteln erfolgt. Der Vorschub des Schlittens 2 mit dem Formklotz 3 erfolgt durch die Spindel 5, die durch den Motor 6 angetrieben wird. Fbenso erfolgt die Bewegung de: Schlitten 8 durch eine Spindel 9 mit Antriebsmotoi 10.stood clamped in the clamping heads 13 (FIG. 1) and initially with the aid of the hydraulic cylinder 12 \ stretched. Then the carriage 2 moves with the form block 3 against the workpiece 14, which is when further advance of the slide 2 tangentially on the form block 3. The carriages 8 run at the same time on the transverse part 7 of the machine bed towards the middle. This after-running is done by an electric motor e, which is controlled by known means as a function of the profile stress. The carriage 2 with the form block 3 is advanced by the spindle 5, which is driven by the motor 6 is driven. The movement de: carriage 8 also takes place by a spindle 9 with drive motor 10.
