AI Technical Summary

Problems solved by technology

Although the copper pipe cutting knife made of tungsten steel has high hardness, it has poor toughness, and it is easy to chip when cutting, resulting in notches, and the cutting yield is poor.
High-speed steel has good toughness, but poor high-temperature resistance, not only requires low-speed operation, but also needs to add cutting fluid at the same time, so the cutting production efficiency is low

Applying the alloy material described in the present invention to the preparation of copper pipe cutting knives, the obtained copper pipe cutting knives have high hardness, good toughness, high temperature resistance, stable performance and long service life, and can be used continuously for two months No edge chipping occurs, and the cutting edge will not be blunted.

Description

technical field [0001] The invention belongs to the field of knives, and in particular relates to a copper pipe cutting knife and a preparation method thereof. Background technique [0002] Copper tube, also known as copper tube, is a kind of non-ferrous metal tube, which is a pressed and drawn seamless tube. Copper tubes are widely used in conductive accessories and heat dissipation accessories of electronic products due to their strong and corrosion-resistant properties, and are the first choice for tap water pipes, heating and cooling pipes. Copper tubes have strong corrosion resistance, are not easy to oxidize, and are not easy to chemically react with some liquid substances, and are easy to simmer and bend. In practical applications, it is necessary to cut and process the copper pipe billet, so the demand for cutting tools for copper pipes is huge. [0003] The copper pipe cutter in the prior art is made of tungsten steel or high-speed steel. Although the copper pipe...
