DVD升降架斜面小圆柱拉深开裂原因分析及结构改进

Deep drawing crack reason analysis and structure improvement of small cylinder with inclined plane on DVD lifting platform

通过对DVD升降架斜面小圆柱拉深成形过程的分析,从金属材料流动和模具结构方面,阐述了导致零件成形不到位和开裂的原因,并在分析的基础上,对已设计好的模具结构进行了改进和整修。结果表明,解决了斜面小圆柱拉深时产生开裂的问题,生产出了合格的产品零件。

By analyzing deep drawing process of small cylinder with inclined plane on DVD lifting platform, in terms of metallic material flowing and die structure, reasons for defi- cient deformation and cracking were identified. Based on the analysis, improvement and renovation had been made to the designed die structure. The result shows that cracking in deep drawing of small cylinder has been solved and qualified products can be produced.
