- 摘要:
- 针对轮体上各类扇形减重孔的结构特点，研究并总结出适用于各类扇形孔的成型技术。 根据团队多年的模
型制作经验，分别对木模的普铣加工、普铣与模型工配合加工、整体加工、四段加工和数控编程加工等 5 种加工工艺及
特点进行了分析和研究，确定出适用于大型轮体扇形孔、轮毂与轮缘间距小于 50 mm 的扇形孔和轮毂与轮缘间距大于
50 mm 的扇形孔的加工技术，保证了各类结构扇形孔的加工质量和成型效率。
According to the structural characteristics of various fan-shaped lightening holes on the wheel body, the forming technology suitable for various fan-shaped holes was studied and summarized. According to the years of model making experience of the team, five kinds of processing technologies and characteristics of the wood mold, including general milling, general milling and model machining, integral machining, four-section machining and numerical control programming machining were analyzed. The processing technology suitable for the fan-shaped hole of large wheel body, the fan-shaped hole with the distance between hub and flange less than 50 mm and the fan-shaped hole with the distance between hub and flange greater than 50 mm are determined, which ensure the processing quality and molding efficiency of the fan-shaped hole of various structures.
