摘要
为提高热管铣刀的散热效果,借鉴以往热管刀具散热结构的研究成果,建立热管铣刀散热基本结构,然后对该结构进行刀具散热性能的优化.通过铣削测温实验评价各种结构的优劣,获得热管铣刀的散热优化结构.基于该优化结构设计并制造出散热性能优良的热管铣刀,并通过切削测温实验验证该优化结构的有效性.切削区温度场反求的结果表明:经散热基本结构优化的热管铣刀,其散热性能有效提高;在某工艺条件下,相比普通铣刀,热管铣刀切削区的温降达35℃以上.
In order to improve the heat dissipation of the heat-pipe milling cutter, the previous achievements on the thermal structure design of the cutter are analyzed, and the basic thermal model of the cutter is constructed. Then, the heat dissipation performance of the cutter is optimized. Moreover, the advantages and disadvantages of various structures are evaluated via milling temperature measurements, and an optimal structure for thermal dissipation is obtained. Based on the optimal structure, a milling cutter with excellent thermal dissipation performance is designed and fabricated. Finally, the effectiveness of the optimal structure is verified by cutting temperature measurements. The inverse solution results of the temperature field in the cutting zone demonstrate that the milling cutter with optimized basic structure effectively improves the heat dissipation performance, and that, when the milling cutter with heat pipe cooling is used, the temperature decrement in the cutting zone reaches 35 under certain technical conditions.
