A method of thermo-mechanically processing a preform composed of tool steel and a tool 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 and a die press system utilizing the thin die and a die press, such as a platen die press or a roller die 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 border around the peripheral edge of the base. A thin die is housed in the indentation of the base. The thin die is positioned in the indentation and adhered using an adhesive, such that the raised portions of the thin die are facing away from the indentation in the base. 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 ejects a cut shape out of the sheet material.

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.

Cutting tool for flat materials. The cutting tools includes a band-shaped base body which has on one longitudinal side a working region with cutting teeth and on an other longitudinal side a supporting region with a supporting surface. The cutting teeth are formed with tips and include cutting sides emanating from the tips at an angle a to one another. In a longitudinal direction of the working region, the tips of adjacent cutting teeth have different distances to the supporting surface.

The present invention relates to a super absorbent resin cutting device and a super absorbent resin manufacturing method using the same. The super absorbent resin cutting device according to the present invention includes: an introduction unit for introducing a super absorbent resin; a cutter for cutting the super absorbent resin into pieces; and a discharge unit for discharging the super absorbent resin that has been cut.
摘要:
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.

Stamping tool, in particular a cutting rule, for dividing or perforating flat materials, and production of the tool. To create a stamping tool with improved properties, in particular with an automatic leveling in a flat-bed stamping machine and/or in a rotation stamping machine, embodiments provide that from a thermally treated and/or quenched and tempered steel strip, shaped on the narrow sides with, on the one hand, a back part with a convex contour in cross section or a contour composed of several projecting convex regions, which contour has recesses in some places transverse to the longitudinal extension and perpendicular to the lateral surfaces, shaped in a chipless manner by cold forming or embossing with free spreading of the material, wherein the extent of the spreading is smaller than the steel strip thickness and the undeformed regions between the recesses can be plastically deformed with a startup of the tool.
