Conduction cooling and milling knife for dry milling

Abstract

The invention provides a conduction cooling and milling knife for dry milling. The conduction cooling and milling knife for dry milling comprises a hilt and a milling knife body mounted at the lower end of the hilt, and further comprises a heat-conduction cooling bar and a plurality of cooling fins; and the heat-conduction cooling bar is arranged in the center of the milling knife body, the outersurface of the heat-conduction cooling bar is attached to the inner surface of the milling knife body, the upper end of the heat-conduction cooling bar extends out from the inside of the milling knifebody, and the cooling fins are attached to a peripheral surface of the extending end; and a heat exchange cavity is formed in the center of the hilt, cooling liquid which communicates with the heat exchange cavity enters a channel and cooling liquid flowing-out channels, the extending end of the heat-conduction cooling bar and the cooling fins which are welded to the extending end are accommodated in the heat exchange cavity, and the heat conductivity coefficient of the heat-conduction cooling bar is higher than that of the milling knife body. By a heat conduction principle, the knife is cooled in a dry cutting and milling process, and therefore, dry cut materials can be milled effectively.

Description

technical field [0001] The invention belongs to the technical field of machining, in particular to a conduction cooling milling tool for dry milling. Background technique [0002] In the milling process, adding cutting fluid to the milling part has the functions of cooling, lubricating, cleaning, cutting and rust prevention, so cutting fluid is widely used in the milling process. However, for the processing of some special materials, such as carbon fiber materials, cutting fluid cannot be added during milling, and only dry cutting can be performed. [0003] At present, in the process of dry cutting, only the air cooling method of blowing cold air to the tool can be used. The cooling effect is not good, the processing efficiency is low, and the service life of the milling tool is short. Contents of the invention [0004] In view of the above-mentioned problems in the prior art, the present invention provides a conduction cooling milling tool for dry cutting, which utilizes...
