Embodiment

[0049] In the material selection of the present invention, scrap steel material is used as the base material, the material content is adjusted to C0.7%, Cr7%, Mo1.5%, and the W content is increased by 0.2-0.3%, in order to reasonably promote the formation of carbides and refine them to the greatest extent Organization, enhance the toughness of the material, improve the service life of the product, so that the composition is controlled at (mass percent): C:0.6-0.7, Cr:6.2-7.8, Mo:1.2-1.8, W:0.2-0.3, V:1.7-2.2 , Si: 0.5-1.8, Mn: ≤0.4, P ≤ 0.03, S ≤ 0.03.

[0050] Melt the scrap steel, supply oxygen to the electric furnace melting pool, oxidize the carbon in the furnace charge to the specified range; remove S, P, O in the raw material and gas such as H, N and non-metallic inclusions in the steel by slagging to ensure the quality of the steel Quality; adjust the alloy composition to meet the requirements of the tapping temperature. LF+VD refining process equipment is adopted. Th...

Abstract

The invention discloses a method for producing upper and lower blades of an edge cutting machine and belongs to the technical field of manufacturing of a mechanical shearing tool. The method comprises the following steps of: firstly smelting an alloy to control the alloy to comprise the following components in percentage by weight: 0.6 to 0.7 percent of C, 6.2 to 7.8 percent of Cr, 1.2 to 1.6 percent of Mo, 0.2 to 0.3 percent of W, 1.7 to 2.2 percent of V, 0.5 to 1.8 percent of Si, less than or equal to 0.4 percent of Mn, less than or equal to 0.03 percent of P, less than or equal to 0.03 percent of S and the balance of Fe; then carrying out continuous casting and heat processing; manufacturing and processing a processing clamp for the upper blade of the edge cutting machine; then, manufacturing and processing the upper blade of the edge cutting machine; and finally manufacturing and processing the lower blade of the edge cutting machine. By means of the method disclosed by the invention, the working service life of the blades of the edge cutting machine can be improved, the indexes of the blades reach the same level with that made by foreign countries, the auxiliary production processing time of the blades is shortened, the efficiency of processing the tool is improved and the stability of the processing precision is improved. The method is convenient for realizing automation of the production process of the blades.

Description

technical field [0001] The invention belongs to the technical field of mechanical shearing cutter manufacturing, in particular to a method for producing upper and lower blades of an edge digging machine. Background technique [0002] During metal shearing, the cutting part of the tool does the cutting work directly. The quality of the tool material directly affects the quality of the tool, the shearing productivity, the durability of the tool, the machining accuracy of the part, and the surface quality. The performance of tool material depends largely on the choice of tool material and the processing technology of the tool. During the metal shearing process, the shearing tool not only bears a large impact load but also withstands a large mechanical friction. Therefore, the tool material must have good hardness, heat resistance, wear resistance and sufficient strength. [0003] 7Cr7Mo2V2Si, referred to as LD (LD-1), is a cold work die steel with twice the strength and toug...
