Manufacturing method of primary strengthening phase fiber vertically aligned high-strength and wear-resistant tool

Abstract

The invention discloses a manufacturing method of a primary strengthening phase fiber vertically aligned high-strength and wear-resistant tool. The manufacturing method comprises the following steps: carrying out multi-pass directional rolling on a rectangular steel billet, wherein the steel billet can be enabled to deform plastically in the length direction and the height direction only during rolling, and does not deform plastically in the width direction, after rolling, a rectangular plate in which a plurality of streamlined fibers of linear strengthening phase and structural constituents are uniformly distributed is formed, and the extending directions of the streamlined fibers are the same with the length direction of the plate; and then blanking the rolled plate to form a tool body blank, enabling a cutting surface during blanking to be perpendicular to the streamlined fibers, and quenching, tempering and sharpening the tool body blank to obtain the primary strengthening phase fiber vertically aligned high-strength and wear-resistant tool. By the tool manufactured by the invention, the tool body is enabled to have the highest tensile strength in the thickness direction, so that the tool has long service life, and the wear resistance of the tool is greatly improved.

Description

technical field [0001] The invention relates to a preparation method of a high-strength and wear-resistant cutting tool with vertically oriented primary reinforcement phase fibers. Background technique [0002] Knives are commonly used tools in daily production. Industries such as textiles, clothing, papermaking, printing, meat processing, metal products, and machinery manufacturing all need cutting knives to cut various fabrics, paper, animal bones, and metals. cropped. With the continuous improvement of human living standards, the requirements for various types of cutting are increasing, so the requirements for the wear resistance, toughness and fatigue strength of the cutting tools are getting higher and higher. Therefore, there is an urgent need for higher wear resistance. , A new tool material with higher tensile strength and higher fatigue strength. [0003] Through the force analysis and failure analysis of a large number of tools, it is determined that when the too...

Problems solved by technology

[0005] The existing cutter body is not strengthened by the vertical orientation of the reinforcement phase fibers in the thickness direction, and the two sides of the blade are not reinforced by the uniformly distributed spherical reinforcement phase, so the wear resistance cannot be increased when it is violently rubbed against the material to be cut, that is, there is no Improve the wear resistance of the tool itself and the tensile strength in the thickness direction of the tool body
