Description

Technical Field

[0001] The utility model relates to the field of cutting tools, in particular to a wear-resistant deburring shear blade. Background Art

[0002] Cutting tools are a common tool in daily life. Tools used for cutting in mechanical manufacturing are called cutting tools. Most cutting tools are machine-used, but there are also hand-used ones. Since the cutting tools used in mechanical manufacturing are basically used for cutting metal materials, the term cutting tool is generally understood to refer to metal cutting tools.

[0003] Tools are divided into deburring tools and cutting tools. However, when using current deburring tools, the deburring blade usually rotates to remove burrs from the aperture. When replacing the deburring tool, the deburring tool needs to be replaced as a whole, and it is difficult to disassemble and replace the deburring blade, which increases the cost of using the deburring tool. For this reason, we propose a wear-resistant deburring shear blade to solve the above problem. Utility Model Content
