Abstract

The invention discloses a slitting cutting disc and a preparation method thereof, which belong to the process field of cutters. The slitting cutting disc is of a circle blade, and comprises a center hole, a cutter disc and a blade, wherein the center hole is arranged in the center of the cutter disc, the blade is arranged on an outer ring of the cutter disc, a blade opening is arranged on an outer ring of the blade, and the opening angle delta ( ) of blade opening is 23-27 degrees. The opening thickness h of the blade opening is 0.24-0.26mm. The materials which are made into the slitting cutting disc comprise components with percentage by weight: carbon (C) 1.15-1.33%, nitrogen (N) 0.2-0.4%, manganese (Mn) 0.30-0.40%, silicon (Si) 0.52-1.20%, chromium (Cr) 8.50-10.50%, tungsten (W) 1.50-2.50%, vanadium (V) 0.35-0.50%, molybdenum (Mo) 0.25-0.4%, nickel (Ni) 0.30-0.40%, copper (Cu) <=0.30%, sulphur (S)<=0.020% and phosphorus (P)<=0.027%, and the allowance is ferrum (Fe). The slitting cutting disc has the advantages that the slitting cutting disc is excellent in abrasive resistance and is not easy to deform, and the blade opening resists abrasion, not easy to crack, long in service life and easy to make.

Description

technical field [0001] The invention belongs to the field of cutter processing, and more specifically relates to a cutting disc cutter and a manufacturing method thereof. Background technique [0002] The disc knife is one of the important parts of the slitter equipment. Generally, it is determined which slitter blade to choose according to the type and thickness of the slitting material. Generally, the slitting form of the slitter blade includes square knife slitting and round knife slitting. The square knife slitting is like a razor, the blade is fixed on the knife holder of the slitting machine, and the knife is dropped during the material running, so that the knife cuts the material longitudinally to achieve the purpose of slitting. There are mainly two ways of circular knife slitting: upper and lower disc knife cutting and circular knife extrusion slitting. Round knife slitting is the main slitting method for slitting thick film, composite thick film, paper and other...
