    摘要： The present invention relates to a blade for cutting machines and to a method for producing such a blade. The blade has a main body made of a first material and a cutting body made of a second material and having at least one cutting edge formed thereon. The second material has a higher hardness than the first material. The cutting body is joined along a joining line to the main body. According to the invention, the blade is produced by: a) providing a support made of a third material of high thermal conductivity; b) placing the main body on the support such that a base area of the main body and a surface of the support lie substantially parallel to each other and the joining line is adjacent the surface of the support; c) generating the cutting body by build-up welding of the second material onto the first material along the joining line, the support being arranged for mechanically supporting the second material used for build-up welding and d) sharpening the cutting body to form the at least one cutting edge

    摘要： A composite utility knife blade and method of making such a blade involves butt joining a tool steel wire to a front edge of an alloy steel backing strip. The wire is electron beam welded to the backing strip to form a composite strip defining a first metal portion formed by the alloy steel backing strip, a second metal portion formed by the tool steel wire, and a weld region joining the first and second metal portions. The composite strip is then annealed, and the annealed strip is straightened to eliminate any camber therein. The annealed composite strip is then hardened such that the first metal portion defines a surface hardness within the range of approximately 38 Rc to approximately 52 Rc, and the second metal portion defines a surface hardness within the range of approximately 60 Rc to approximately 57 Rc.

    摘要： The invention relates to a chipper knife of the type that is adapted to be mounted in chippers which have a rotatable tool, in the form of a disc, drum or frustoconical member, on which are mounted a plurality of such chipper knives to provide, during rotation of the tool and simultaneous feeding of pieces of wood to the same, material-cutting working or disintegrating of the pieces of wood into chips by means of at least one cutting edge (1, 1′). At least a first side of the chipper knife has a raw, unworked surface or working stripes in the longitudinal direction of the chipper knife, that is substantially parallel to the cutting edge. This first side also has a thickened cutting edge portion (5, 5′) in the area next to the cutting edge, which edge portion has working stripes in the transverse direction of the chipper knife, at an angle to the cutting edge. The invention also relates to a method of manufacturing such a chipper knife.

    摘要： A method for directly forming a cutter mold with double etching and an apparatus thereof includes the following steps: a metal plate for being made, the cutter mold is tightly pressed with a light-resisting agent membrane first, an image of cutter mold drawing, which provides lines with widths thereof being one fifth or one tenth of the lines on the ink drawing of conventional cutter mold, is transferred to the light-resisting agent membrane. The thinner lines perform obstructing the etching liquid, which sprays toward the membrane to etch the work. Finally, the unnecessary membrane is peeled and two lateral sides of the formed cutter mold are etched with light etching liquid to complete the cutter mold with a sharp blade.
