Integral axial rotation oscillating heat pipe grinding wheel and manufacturing method thereof

Abstract

The invention discloses an integral axial rotation oscillating heat pipe grinding wheel and a manufacturing method thereof. A plurality of oscillating heat pipe flow channels arranged axially are machined inside a grinding wheel body. The oscillating heat pipe flow channels are connected end to end through communicating flow channels in sequence to form a closed S-shaped oscillating heat pipe structure. The lower end of the grinding wheel body is provided with an end cap cavity. The oscillating heat pipe structure communicates with a liquid filling hole through a liquid filling groove. The liquid filling hole is formed in the cavity bottom of the end cap cavity. An end cap can be inserted into the end cap cavity to seal the liquid filling hole. The oscillating heat pipe structure is vacuumized, and a cooling medium which the oscillating heat pipe flow channels are not full of is filled into the oscillating heat pipe structure, so that the lower portions of the oscillating heat pipe flow channels are filled with the cooling medium, and the upper portions of the oscillating heat pipe flow channels are empty. Cooling fins are machined on the peripheral surface of the upper portion ofthe grinding wheel body. The integral axial rotation oscillating heat pipe grinding wheel has the advantages that the grinding wheel can stably, continuously, effectively and rapidly conduct out grinding heat in a grinding arc region, enhance the heat exchange effect of the grinding arc region, reduce the grinding temperature and improve the grinding quality.

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
