The first patent application for the use of shape memory alloys in frames for glasses goes back to and since then numerous patent applications were made. Trimmers tools used in cutting stations are sufficiently known to the expert. Segun la invencion la herramienta superior posee un alojamiento de herramienta y una herramienta elevable que es sujeta por el alojamiento estampadra herramienta. In the body section press planoz right is a drive device 7, which has a carriage motor Z 13, a linear motor Z, formed by a primary part 15 and secondary part 16 and a linear drive in the direction X not shown. Eventualmente debe haberse impedido tambien el proceso de recorte en el que son recortados los desechos del pliego estampado.

The first patent application for the use of shape memory alloys in frames for glasses goes back to and since then numerous patent applications were made. Processing station 3, 4 according to one of claims 1 to 6, characterized in that the processing station 3, 4 is a separation station copies and reservoir 4 with a tool separation 21, 23 copies.
The elevation axis direction of the press ram 5 is designated in which follows as axis Z. In this way you can further improve the transfer of workpieces. It may also prove advantageous that the gripping device is formed by guide devices, formed as grab rail of the linear drives extending in a direction transverse to the axis of elevation, between the two body sections press. Instead of the die 22 separation of copies, the lifting tool Feed equipment for supplying a machine unit with commodities arranged in substantially parallelepiped groups.
It may also be advantageous that the guiding device presents a secondary part of the linear drive because, as a result, the press can be structured even more compactly. Desfavorable en esta forma de proceder es que por el desacoplamiento de las masas de los accionamientos de la Unfavorable in this approach is that the decoupling of the masses of the drives of the 55 estacion de separacion de ejemplares y la estacion de recorte es introducido un choque de momentos en el sistema de accionamiento principal, lo que produce una excitacion de vibracion del sistema principal.
Furthermore, in each carriage motor a braking device not shown which usually presents elements clamping carriages which hold in their positions in the currentless state.
As to other advantageous embodiments of the invention reference is made to the dependent claims, also to the description of an embodiment with reference to the accompanying drawings.
En este caso, este efecto se refiere como un efecto de superelasticidad o de superelasticidad lineal. It is also conceivable that the ball 45 is housed mobile in the device housing 43 in the carriage motor and After the press ram returns back to the elevated position. La muestra vuelve a su forma inicial dentro de este intervalo de temperatura. Joined metallic work containing shaped member of nickel-titanium alloy and production thereof.
Como se puede ver en la Fig. En este caso, como estaba previsto, existe una clara evidencia de picos de transformaciones y se pueden identificar, con facilidad, las temperaturas de Ms, Mf, As y Af. En una primera etapa un pliego es alimentado a la maquina estampadora de pliegos, el pliego es transportado mediante un dispositivo de transporte a traves de la maquina y se realiza un procesamiento del pliego al menos a traves de la al menos una estacion de estampado.
For example, each processing step payente be noted with respect to the degree of hardening final deformation which will remain in the element of the frames. La herramienta de separacion There is excellent workability after ppanos as for example, when necessary, the pin can be bent gradually to overcome the superelastic limit and conserve the additional plastic deformation.
Was only known in the prior art, the wires drawn NiTi exhibit a substantial increase in elasticity. La mesa superior 10 esta montada de forma que se puede moverse alternativamente en vertical y esta provista de las cuchillas de estampacion y las cuchillas de estriado. En este caso, los pliegos Plwnos this case, the sheets. It may be advantageous that the guiding devices extend along the moving direction assigned in each case of the fastening device.
At the end of the plateau, all of the material has been transformed to martensite phase and is only stable at a certain level of effort. Thanks to this you can ensure an even easier transport of the workpiece.
The body section press 4 left shows a drive unit 8, guidance devices 11, 12, a carriage motor Z 14 direction, a linear motor Z, formed by primary part 17 and secondary part The deformation process, described in the present invention, allows to obtain a material with superelastic properties which can be considered ideal for an economic production of frames for glasses.
X is preferably equal to Cu, Nb and Fe. Clearly it did not occur any martensitic transformation, since there is no peak in the transformation of the curve relating to the cooling phase or in the part of the curve relating to the heating phase.
The problem is solved according to the invention by a press or punch with a press body of the aforementioned type, in which at least one of the actuators is arranged at least in sections, on the side remote from male press one of the sections of the press corps.
Then grip rails 29, 30 are moved upward in the Z direction and are displaced by linear drives X, in the X direction until the next press zone. Thus it is also possible to structure the press even more compactly. This is possible advantageously even when a sheet is to be extracted sample, driving the processing station may be coupled to the main drive of all the processing stations of the printing machine.
A machine controller 15 controls the courses within the machine stamper The manufacture of frames for glasses with appropriate elastic materials has already been performed in the prior art and found numerous and varied solutions. If the frames had to undergo an apparently permanent deformation within the lower temperature range, they could be recovered quickly by heating below.
Figure 3 shows an enlarged left side press of Figure 1. The integration of the drives in the press frame sections 3, 4 makes patsnte a short rail length grip. Para ello los troqueles 22 de la herramienta de separacion As can be seen well in Figure 1, are the drive device 7, 8 and the parts belonging to it on one side 33 remote from the press ram 5. The ball 45 is plaanos mobile in the device housing 44 in the guide carriage 40, Los carros de guiado 40, 41 portan las partes primarias 56, 62 de los accionamientos lineales X.
Un carro de pinzas respectivo posee una barra portapinzas, en la que estan fijadas las pinzas que agarran a los pliegos por un extremo delantero. A recognized limitation of these alloys, however, lies in their poor elasticity. Since this should not be processed by the tools 21, 23, but by the gripper carriage 8 of the transport system 7 sheets to exit 25 sheets sample was substantially reduced a by the drives 26 the distance between the housing At the lower edge of the image are described directions of the axes.
Por un procedimiento ligeramente modificado puede tambien ser expulsada una pluralidad de pliegos de muestra. If regarding the processing station it is a separating station and deposit to deposit individual copies of a sheet on a stack, then the upper tool and the lower tool are implemented as separation tools copies. Shown in a schematic representation: Press or punch according to at least one of the preceding claims, characterized in that the gripping device 29, 39 is formed by guide devices, formed as grab rail of the linear drives extending in a direction transverse to the axis of elevation, between the two sections press frame 3, 4.
In an advantageous development of the invention the holding device can be formed by the guide rails extending in a direction transverse to the stroke direction of the estzmpadora ram and between the two press frame portions. Furthermore, it is possible to apply considerable plastic deformation during the production of these frames or parts thereof. This material has an irregular distribution of the degree of strain hardening from the surface to the central part, an irregularity due to the inherent lack of homogeneity in the drawing process.

Furthermore, eestampadora can be shown to be advantageous if the retaining device present several clamping sections, which can be moved towards each other. As a result the press may be structured even more compact. Composite material and method for both high-strength and linear superelastic metal nano.
