An integral axially rotating oscillating heat pipe grinding wheel and its manufacturing method

Abstract

The invention discloses an integral axially rotating oscillating heat pipe grinding wheel and a method thereof. The inside of the grinding wheel body is processed with a plurality of oscillating heat pipe flow channels arranged axially, and the oscillating heat pipe flow channels are sequentially connected end to end through connecting flow channels. Closed serpentine oscillating heat pipe structure. The lower end of the grinding wheel body is provided with a plug cavity, and the oscillating heat pipe structure communicates with a liquid injection hole through a liquid injection groove. The liquid injection hole is opened at the bottom of the plug cavity, and a plug can be inserted into the plug cavity to seal the liquid injection hole. The oscillating heat pipe structure is evacuated and injected with cooling medium that is not filled with the oscillating heat pipe flow channel, so that the lower part of the oscillating heat pipe flow channel is filled with cooling medium while the upper part is a cavity, and heat dissipation fins are processed on the upper peripheral surface of the grinding wheel body. The invention has the advantages that the grinding heat in the grinding arc area can be effectively and rapidly discharged stably and continuously, the heat transfer in the grinding arc area can be strengthened, the grinding temperature can be reduced, and the grinding quality can be improved.

Description

technical field [0001] The invention belongs to the technical field of grinding, and in particular relates to an integral axially rotating oscillating heat pipe grinding wheel and a manufacturing method thereof. Background technique [0002] Grinding, especially high-efficiency grinding, generates a lot of heat because only a small amount of coolant enters the grinding area, so a small part of the grinding heat is carried away by the coolant and grinding chips, while most of the heat remains Accumulated in the grinding arc area, causing the temperature of the grinding arc area to rise, resulting in burns, oxidation, thermal damage such as residual stress and micro-cracks on the surface of the workpiece, as well as the blockage of the grinding wheel and the passivation of the abrasive grains. Therefore, it is necessary to strengthen the heat transfer in the grinding arc area, so as to evacuate the grinding heat. [0003] The oscillating heat pipe is a new type of heat pipe, ...

AI Technical Summary

Problems solved by technology

[0005] In view of the lack of heat transfer capacity of the grinding arc area in the existing grinding process and the problem of the combined oscillating heat pipe grinding wheel, the present invention provides an integral axially rotating oscillating heat pipe grinding wheel and a preparation method thereof. The oscillating heat pipe grinding wheel can stably and continuously dissipate the grinding heat in the grinding arc area effectively and quickly, strengthen the heat transfer in the grinding arc area, reduce the grinding temperature, and improve the grinding quality
