Abstract

The invention discloses a preparation method for an ultrafine-grained hard alloy striping and slitting tool, and belongs to the technical field of hard alloy tools. The preparation method for the ultrafine-grained hard alloy striping and slitting tool, which is disclosed by the invention, comprises the following steps: (1) material preparation: striping and slitting tool materials are prepared according to the components of the materials; (2) the mixed materials are grinded and dried, and then rotationally distributed and pressed into blanks, the rotational material distribution is carried out by virtue of a rotary-disc material distribution device, and the rotary-disc material distribution device comprises a disc, an outer circular ring, an inner circular ring, a central circular ring, a first cushion block, a second cushion block and a rotary base; and (3) after the blanks are formed by pressing, a sintering procedure of powder metallurgy is carried out, and then cooling is carried out after completion of the sintering. According to the invention, a high-performance high-accuracy slitting and shearing tool can be produced, the tool is high in hardness, strength, wear resistance and toughness, and the quality and the comprehensive use performance of the tool occupy domestic leading positions.
