Abstract: A stamping tool formed from a steel strip and method of forming the stamping tool. The stamping tool is formed from a steel strip shaped on a narrow side with a cutting part having a cutting edge. The stamping tool includes a back part with a contour in cross section on a narrow side of the steel strip, recesses shaped in the back part with free spreading of the material to be transverse to a longitudinal extension of the steel strip and perpendicular to lateral surfaces of the steel strip, such that an extent of the spreading is smaller than a thickness of the steel strip, and undeformed regions located between the recesses.

Abstract: 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.

Abstract: The present invention relates to a method for manufacturing of preforms (15, 25) for saw blades respectively saw bands, comprising the following steps (a) arranging a strip (30) of a cutting material for a cutting edge of saw blades respectively saw bands without any play between the edges (12, 22) of a first carrier band (10) and a second carrier band (20); (b) guiding of a laser or electron beam (40) along a first edge (32) of the strip (30) for welding part per part of the first carrier band (10) to the strip (30), wherein regions (36) along the first edge (32) of the strip (30) remain unwelded; (c) guiding of a laser or electron beam (40) along a second edge (34) of the strip (30) for welding part per part of the second carrier band (20) to the strip (30), wherein regions (36) along the second edge (34) of the strip (30) remain unwelded; and (d) guiding a laser, water or electron beam (50) between the first edge (32) and the second edge (34) of the strip (30) or the second edge (34) and the first edge (32

Abstract: The present invention relates to a steel band 1 for the manufacturing of doctor blades, coater blades or creping blades comprising a steel composition comprising in percent per weight 1-3% C, 4-10% Cr, 1-8% Mo, 2.5-10% V and the remainder essentially iron and contaminants in normal amounts, wherein the steel band 1 is produced by using a powder metallurgical process. Further, this invention relates to doctor blades, coater blades or creping blades of this steel band, as well as a method for its manufacture.
