Problems solved by technology

However, for 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, only the air cooling method of blowing cold air to the tool can be used in the process of dry cutting. The cooling effect is not good, the processing efficiency is low, and the service life of the milling tool is short.

Abstract

The invention provides a conduction cooling milling tool for dry milling, which includes a handle and a milling cutter installed at the lower end of the handle, and also includes a heat conduction cooling rod and a heat sink; the heat conduction cooling rod is arranged at the center of the milling cutter , the outer surface of the heat conduction cooling rod is attached to the inner surface of the milling cutter, the upper end of the heat conduction cooling rod protrudes from the milling cutter, and the outer peripheral surface of the extension end is fitted with a number of cooling fins; the center of the handle is provided with The heat exchange cavity, the coolant inlet channel and the coolant outflow channel connected with the heat exchange cavity, the extended end of the heat conduction cooling rod and the heat sink welded on the extended end are all accommodated in the heat exchange cavity. The thermal conductivity of the thermally conductive cooling rod is higher than that of the milling cutter. The invention utilizes the heat conduction principle to realize the cooling of the cutting tool during the dry cutting and milling process, so as to realize the effective milling of the dry cutting material.

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...
