摘要:
The invention relates to a method for operating a punching/transferring device (1), in particular for producing RFID in antennas. The punching/transfer device (1) has a punching tool (2) with a vacuum connection (3), said vacuum connection (3) interacting with a porous elastomer (9) such that by means of the punching tool (2), a desired contour can be punched out of a multilayer composite, held, and then dispensed by modifying the shape of the porous elastomer (9) and/or by modifying the vacuum.

A steel plate for band-shaped die-cutting blades has a base part to a depth of more than 200 μm from the steel plate surface and a chemical composition containing 0.40 to 0.80 mass % C and 0.10 to 0.50 mass % Nb. A spherical carbide constituted of cementite is present in the bainite or tempered martensite structure of the blade in an amount of 1.0 vol % or more. A Nb-containing carbide having an equivalent-circle diameter of 0.5 μm or more is present at an existential density of 10.0 or more grains per 900 μm2. The base part has a controlled hardness of from 300 to 450 HV. The surface layer part has a decarburized surface layer of ferrite single-phase and a thickness of 5 μm or more. In a 15-μm-thick surface layer region, the existential density of the Nb-containing carbide is from 0 to 5.0 grains per 900 μm2.

Tools with a thermo-mechanically modified working region and methods of forming such tools. The tool includes a working region containing steel altered by a thermo-mechanical process to contain modified carbide and/or alloy bands. In use, a surface of the working region contacts a workpiece when the tool is used to perform a metal-forming operation.

Disclosed is a flex die punching apparatus for forming an aperture in at least one sheet of material. There is a flexible, extrudable platen which, upon exertion of a force against it, extrudes at least a portion of at least one sheet of material through an aperture of a die. The flexible, extrudable platen may have a punch feature, corresponding to the shape and position of the die aperture, which assists in the extruding of the flexible, extrudable platen through the die aperture and also in the formation of the aperture in the sheet of material. In another embodiment of the invention, there may be a second die wherein the at least one sheet of material is placed between the first and second dies to form the aperture in the sheet of material.

A method of forming a rotary cutting die includes the following steps. A curved cutting rule transfer plate including an inner surface and an outer surface is provided. A cutting rule channel is formed in the transfer plate, and defines a predetermined design. A cutting rule having a cutting edge and a support edge is placed in the cutting rule channel. The support edge of the cutting rule extends from the inner surface of the transfer plate. A translucent rotary die place is formed on the inner surface of the transfer plate. The support edge of the cutting rule extends into and is supported in the rotary die plate. The transfer plate is then removed from the rotary die plate.

Methods of thermo-mechanically processing a preform composed of tool steel and tools to modify a workpiece. The preform has a region containing austenite. The method comprises establishing the region at a process temperature between a martensitic start temperature and a stable austenitic temperature. While at the process temperature, the region is deformed to change an outer dimension and to modify the microstructure to a depth of 1 millimeter or more. The tool comprises a member composed of tool steel. The member includes a first region that extends from the outer surface to a depth of greater than 1 millimeter and a second region. The first region includes a plurality of grains having an average misorientation angle greater than about 34°, an average grain size that is at least 10% smaller than the second region, and has a different grain orientation than the second region.

Disclosed is a thin die adapted to be used in a press. The die disclosed herein includes a base or backing portion that provides rigidity to the die assembly. The base includes an indentation defining a boarder around the peripheral edge of the base. A thin die is housed in the indentation of the base and the thin die is adhered to the indentation of the base by an adhesive. The thin die is positioned in the indentation of the base so that raised portions of the thin die are facing away from the indentation in the base to allow the thin die to cut into a sheet material. Ejection foam is adhered to the raised portion side of the thin die by an adhesive so that the ejection foam protects the raised portion of the thin die and provides an ejection means of the cut shape out of the sheet material. Also disclosed is a die and press system utilizing the thin die disclosed herein. Included in the system is a die press, which may be a platen die press or a roller die press. The die press includes a cutting pad that allows the die to cut through the sheet material and into the cutting pad, if a platen die press is used. The system further includes a thin die adapted to be used with a die press. The thin die includes a base portion, a thin die portion, and an ejection foam portion, wherein the base portion and the ejection foam portion sandwich the thin die portion so that the thin die is located in an indentation located in the base and is adhered to the base by an adhesive. Further, the ejection foam portion is adhered to the thin die portion so as to protect raised portions of the thin die portion. The ejection foam protects the raised portions of the thin die portion and acts as an ejection means to eject the cut shapes from the sheet material.
