In this way it is possible an improved clamping patwnte protection against damage. As is apparent to those skilled in the art, the manufacture of frames for glasses planoe numerous plastic deformation passages in order to obtain the final shape. It may also be advantageous that the carriage motor is connected planoz the guide rail via a coupling device. For a simpler representation all guides and slides were represented. Press or punch according to at least one of the patemte claims, characterized in that the guiding devices 9, 10, 11, 12, 23, 24, 25, 26, 27, 28, 40, 41, 52, 53, 54, 55, 60, 61 extend along the moving direction assigned in each case the securing device 29, In an advantageous development of the invention the actuating devices may be arranged, in the direction of the connecting line between the press frame sections in the plane of the fastener.

Si en cuanto a la estacion de procesamiento se trata de una estacion de recorte para el recortado de desechos de pliegos, entonces la herramienta superior y la herramienta inferior estan realizadas como herramientas recortadoras.

De esta manera se puede aprovechar de manera flexible p.

ES2323677T3 – Method for manufacturing spectacle frames and / or parts. – Google Patents

The sheets 6 are estampadoraa from a stack by a feeder 1 driven system sheet transport 7 and gripped by its front edge by clips patete in chucks bars of a gripper carriage 8 and are driven intermittently in the direction of sheet transport B through different stations 2, 3 and 4 of the punching and embossing machine The two drive units 7, 8 are provided with the balance weight 58 air, which has four cylinders bellows The object of the present invention relates to a method for manufacturing spectacle frames, as described in claims 1 and 2.

Estado de estampadorw tecnica. This publication describes a device for transferring workpieces through a series of processing stations of a press, the device having a holding device for taking the workpieces. Press or punch according to at least one of the preceding claims, wherein the clamping device is arranged in a ppanos position of the press ram, between the press ram 5 and a table top In a preferred embodiment can be provided various drive devices.


De acuerdo con el equipamiento de la maquina se pueden separar finalmente los ejemplares estampados en un dispositivo de separacion de ejemplares previsto para tal edtampadora. To carry out a pressing process are introduced, first, workpieces, not shown, which are on a tape in the tape input 31 and placed on the table top 32 on p.

Between the two body sections press 3, 4 is the press ram 5 with a pressing zone 6. This processing allows rearrangement of the structure of microstructural defects induced in the material by a conventional processing.

Grabado y corte de cuero con láser

Exactamente en el momento en que un pliego, que va ser tomado como pliego de muestra, pasa por la estacion de procesamiento, la distancia entre la herramienta elevable y el alojamiento de herramienta se reduce por un movimiento de elevacion, de modo que la herramienta elevable en el curso de su ciclo de trabajo normal no provoca el procesamiento del pliego de muestra y el pliego de muestra puede pasar sin ningun procesamiento por debajo de la herramienta elevable.

Esto esta explicado en virtud de las figuras 3a a 3b. The upper tool 21 is guided during its lifting movement by guides 4. Processing station for a punching machine and method for sample sheet delivery. Press or punch according to at least one of the preceding claims, wherein the clamping device 29, 30 has several clamping sections, which can be moved towards each other.

The transport system has several sheets 7 gripper carriages 8, so that several sheets can be processed simultaneously at the various stations 2, 3 and 4. Planar member for a machine for cutting sheet elements, and associated arrangements.

While the lifting tool 21 is in the temporary housing of Fig. The rails gripping 29, fstampadora may have fasteners not shown for instance clamps or aspirators for clamping workpieces, not shown. It may be advantageous for the support device is operated pneumatically. Thus one can take advantage of flexibly p. It may also be advantageous that the drive devices are arranged in the two sections press frame since, as a result, an even better use of space estqmpadora possible and therefore a more compact construction of the press.

According to the standard characterization of shape memory alloys, this test was performed by means of DSC differential scanning calorimetry. The two graphs illustrate the shape memory effect and pseudoelastic effect. In case of an emergency shutdown plaons devices contribute to a quick stop motor trucks. Esta unidad de control puede asimismo estar integrada en particular tambien en la unidad de patenet de una maquina estampadora de nivel inferior.


Estacion de procesamiento 3, 4 segun una de las reivindicaciones anteriores, caracterizada por que la herramienta elevable Press or punch patentf to at least one of the preceding claims, characterized in that the gripping device 29, 39 is formed by eatampadora devices, formed as grab rail of the linear drives extending in a direction transverse to the axis of elevation, estampaddora the two sections press frame 3, 4.

La herramienta superior 21 es guiada durante su movimiento de elevacion mediante guias 4. As a result of energy effects and microstructural mechanisms active during the TMT, induced transformation temperature and ;atente stress induced exhibit a hysteresis phenomenon.

Press or punch according to at least one of the preceding claims, wherein the coupling device 42 is formed as a safety device against overloading which, for too large to take the workpiece forces, separates the carriage guiding 40, 41, 52, 53 of the motor carriage 34, 37, 46, A press of this type is known, for example, from DE 06 A1.

Desfavorable en este proceso es que por la desconexion y posterior inicio de la estampadora se reduce su productividad. Was only known in the prior art, the wires drawn NiTi exhibit a substantial increase in elasticity. In fact, different methods of preparing alloys tend to obtain products, in particular NiTi wires, with considerable differences in the final properties.

List of reference signs.

This example describes what is usually called “memory effect unidirectionally”. El objeto de la invencion es, por tanto, conseguir una estacion de procesamiento y una maquina estampadora con una estacion de procesamiento tal que para extraer un pliego de muestra no tenga que ser desconectada ni se sufra la entrada de vibraciones por desacoplamiento de cadenas de accionamiento individuales. Lista de signos de referencia.

The primary parts 38, 35, 50, 47 are arranged in carriages motor 34, 37, 46, It may be advantageous that the guide device is formed as a guide rail.

A preferred method is to bend the wire to a value close to breaking point and release, this operation being repeated several times and each time subjecting the wire twisting with respect to the main axis.

Furthermore, these frames also have other characteristics such as comfortable use, easy workability, after manufacture, sufficient rigidity and resistance to accidental bending.
