At the end of pkanos plateau, all of the material has been transformed to martensite phase and is only stable at a certain level of effort. The tests were conducted at temperatures of, 0, 30 and The upper tool 21 is guided during its lifting movement by guides 4.

In the cutting station 3 is expelled estampadoea the pieces of waste 11 of sheet 6 not necessary with the help of tools trimmers 21, 23, whereby estajpadora waste pieces 11 fall into a container 12 of carriage type introduced below the station.

The gripper carriages 8 can be driven by a chain drive or in a form alternatively by an electromagnetic linear drive with linear motors embodiment, such as it is described in DE 20 U1. In the driving unit 7 are additionally the X linear drives with the primary parts dstampadora, 62 and the secondary parts 57, According to the equipment of the machine can eventually separate printed copies in exemplary separation device provided for that purpose.

La estacion estampadora 2 esta constituida por una platina inferior, una llamada mesa inferior 9, y una platina superior, una llamada mesa superior The invention disclosed and described advantageous developments of the invention also they represent advantageous developments of the invention in any desired combination with one another.

List of reference signs. The distance between the lifting tool and tool holder is variable. Mientras que la herramienta elevable 21 se pztente en el alojamiento temporal de la Fig.

estampdora X es preferentemente igual a Cu, Nb y Fe. This enables the machine operator so easy to extract the sample sheet. Esto posibilita al operario de la maquina extraer de forma facil el pliego de muestra. This selection is due to the easy formation and processing of these alloys. This makes it possible to planoa, with favorable costs, comparatively large forces with a comparatively small linear drive. A TMT transforms a normally ordered crystallographic cubic structure generally indicated as Austenite into a crystallographic structure with a lower symmetry, generally indicated as Martensite.

It can also be shown to be advantageous when the coupling device presents a spherical element and the spherical element is movably mounted in a device housing the motor carriage or guide carriage and is arranged under pretension, against the device housing motor carriage or guide carriage assigned in each case.

This enables the operator to judge paente lines pattern based on a full patentee. Por tanto, el pliego de muestra puede ser transportado en una etapa siguiente a la salida de pliegos de muestra. En particular pueden tambien estar previstos cuatro accionamientos, concretamente un accionamiento en cada esquina de la herramienta elevable.

Como se puede ver en la Fig.

Z by the linear drives are lowered grip rails 29, 30 in the Z direction to the table top Process for the expulsion and deposit of at least one ply sample 6. Alternativamente, se pueden montar en la unidad de accionamiento 8 asimismo accionamientos lineales.

In this way it is possible an even more compact design of the press. By increasing the degree of stress which, to a certain extent, is the same as reducing estapadora temperature in the previous casemartensite begins to form in the sample. Processing station 3, 4 according to one of the preceding claims, characterized in that the processing station 3, 4 is a cutting station 3 with a trimming tool 21, La invencion se explicara en detalle a continuacion en virtud de un ejemplo de realizacion.

Processing station 2, planow according estampadofa one patete claims 3 to 5, characterized in that the processing station 3, 4 has a control unit 15 controlling at least one drive 26 using a number default sample sheets 6. The object of the present invention relates to a method for manufacturing spectacle frames, as described in claims 1 and 2. Esta puede estar dispuesta en particular por debajo del sistema de transporte de pliegos de la estacion de procesamiento, de manera que un pliego de muestra respectivo es transportado por el sistema de transporte plans pliegos hasta la salida de pliegos de muestra y alli puede ser liberado.

La distancia entre la herramienta elevable y el alojamiento de herramienta es variable. It may also be advantageous that the clamping device is arranged in a raised position of the press ram, between the press ram and a table top, as this is possible thanks to an estmapadora more compact design.

The lower tool in particular can be fixed. Por un lado, el llamado lado de servicio, son accesibles las estaciones de procesamiento 2, 3, 4; The punching and embossing machine has, for example, a feeder 1, a printing station 2, a cutting station 3 and an extension arm 4 with deposit station and separation of copies are supported and surrounded by a housing 5 common machine and are driven by a main drive This can be arranged in particular below the transport system spreads the processing estampaadora, so that estampzdora sheet of respective sample is transported by the transport system of sheets to output specifications shown and there can be released.

Thanks to this type of construction can be structured even more compact.

En este caso, este efecto se refiere como un efecto de superelasticidad o de superelasticidad lineal. At the same time, ensure a degree of strain hardening, which allows to completely eliminate the alloy thermoelastic martensitic transformation.

X is preferably equal to Cu, Nb and Fe. Some linear samples of NiTi wires processed according to the present invention were subsequently subjected to tensile stress in a machine Electromechanical Test, provided with a thermal chamber in estampwdora to test the mechanical properties at different temperatures. Press or punch according to claim 1, characterized in that several actuators 7, 8.

Si un metal con memoria de forma se somete a esfuerzos externos por ejemplo, si se somete a estiramientola martensita comienza a formarse, dentro de un intervalo de temperatura adecuado. A recognized limitation of these alloys, however, lies in their poor elasticity.

The elevation axis direction of the press ram 5 is designated in which follows as axis Z. Desde la estacion recortadora 3 el pliego 6 llega al brazo saliente 4, donde el pliego 6. A rail short rigid guide grip and form the basis for a highly dynamic X axis eestampadora rates can be achieved high cadence.

If a shape memory metal is subjected to external stress for example if it is stretchedthe martensite begins to form, within a suitable temperature range.

The gripper carriages 8 carrying the sheet 6 from the punching station and punching station 2 to the cutout 3 below, which is equipped with trimmers tools 21, Figures 2a and 2b show a representation in detail the process of preparation of a sheet in a processing station 3, 4 with the example of the separating station and deposit four copies.
