Abstract

The invention discloses a heat pipe cutter and a method for improving radiation of a cutting tool by using the heat pipe. The heat pipe cutter comprises a cutter body, a heat pipe and a fixing device, wherein the heat pipe is axially divided into an evaporation section, a thermal insulation section and a condensation section in turn along the heat pipe; the heat pipe is arranged on the cutter body through the fixing device; the evaporation section of the heat pipe is positioned on a main blade and at the rear end of the cutter point; the evaporation section of the heat pipe is in close contact with the cutter; a space is formed between the thermal insulation section of the heat pipe and the cutter; and the condensation section of the heat pipe is arranged on the outer side of the cutter. The heat mainly produced by the cutter head is conducted to the evaporation section of the heat pipe through the cutter head, the working medium in the evaporation section of the heat pipe absorbs the heat and is boiled, and after phase transition, the high-pressure vapor carrying heat arrives the condensation section after passing through the thermal insulation section and is condensed at the condensation section to release the latent heat, and the capillary attraction liquid depending on a liquid absorption core flows back to the evaporation section again to finish a heat transfer process of one period; and the steps are repeated so that the heat produced by the cutting of the cutter head is constantly transferred to the condensation section from the evaporation section of the heat pipe to be diffused, and thus the temperature rise of the cutter head is effectively avoided.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a heat pipe tool and a method for improving the heat dissipation of the cutting tool by utilizing the heat pipe; the heat pipe tool refers to a tool for metal cutting based on heat transfer of the heat pipe. Background technique [0002] Cutting is still a major forming process in the machinery manufacturing industry. During the cutting process, a large amount of cutting heat is concentrated in the cutting area, which will cause high temperature and rapid wear of the tool, and thermal deformation of the workpiece. The generation of cutting heat is inevitable. How to accelerate the dissipation of cutting heat in the cutting process to avoid overheating of the cutting area is an important issue to ensure the processing quality of the workpiece and the working life of the tool. [0003] In traditional cutting, the method of pouring a large amount of cutting fluid is generally used to take away mos...
