High-temperature-resistant metal cutting tool and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant metal cutting tool and a preparation method thereof. The high-temperature-resistant metal cutting tool comprises the following raw materials in parts by weight: 10-20 parts of a copper-aluminum alloy, 10-30 parts of an iron-titanium alloy, 20-60 parts of styrene, 30-40 parts of methyl benzoic acid, 10-20 parts of sulfite, 2-10 parts of dimyristyl alcohol ester, 30-40 parts of epoxidized soybean oil, 35-45 parts of methoxy polyethylene glycol, 20-30 parts of sodium oleate, 30-80 parts of calcium phytate and 25-35 parts of water glass. The preparation method comprises the following steps: (1) melting the copper-aluminum alloy and the iron-titanium alloy, and cooling for later use; (2) uniformly mixing styrene, methyl benzoic acid, sulfite, sodium oleate, calcium phytate, dimyristyl alcohol ester, epoxidized soybean oil and methoxy polyethylene glycol at 50-60 DEG C, then adding the water glass, and uniformly mixing; and (3) pouring a solution obtained in the step (2) into the step (1), cooling, and then pouring into a cutting tool mold. According to the high-temperature-resistant metal cutting tool disclosed by the invention, the tolerable temperature is 360-380 DEG C, and the hardness is 31-34HRC, so that the high-temperature-resistant metal cutting tool has very good high-temperature hardness and can remain performance at a high temperature.

Description

technical field [0001] The invention belongs to the field of metal tools, in particular to a high-temperature-resistant metal cutting tool and a preparation method thereof. [0002] Background technique [0003] Cutting tools are tools used for cutting in mechanical manufacturing. The vast majority of knives are for machine use, but some are also for hand use. Since the knives used in mechanical manufacturing are basically used to cut metal materials, the term "knife" is generally understood as a metal cutting tool. The structure of various tools is composed of a clamping part and a working part. The clamping part and the working part of the integral structure tool are all made on the cutter body; the working part (knife tooth or blade) of the insert structure tool is mounted on the cutter body. There are two types of clamping parts with holes and handles. The tool with a hole is set on the main shaft or mandrel of the machine tool by means of the inner hole, and the t...
