落料拉深成形工艺及模具设计 摘要：设计着重介绍了制件的成型工艺，及模具结构设计。通过对制件的工艺分析，确定了工艺方案。并设计了一套倒装复合模具。在设计同时利用参考资料，确定了各工作零件的尺寸。并较多的考虑了模具结构的调整性、易更换性及模具成本。同时在模具设计内容中融汇了冲压模具的不同加工方法、加工工艺及装配工艺，对初学冲压模具模设计者有一定的参考价值。本设计从模具设计到零部件的加工工艺以及装配工艺等进行详细的阐述，并应用CAD进行各重要零件的设计。制件是带凸缘的筒形件，选择合适的压边力是极为重要的，它具体应在保证不起皱的前提下取最小值。卸料板在落料前兼起压料作用。 本复合模具先由凸凹摸与落料凹模进行落料拉深工序，后进行冲孔工序。此外，在排样的工作中力求板材利用率达到较高的水平。关键词： 落料拉深模 复合模。Blanking and deep drawing die design process Abstract: The design focuses on the parts of the forming process and die structure design. Parts of the process through the analysis of the process program. And design a set of flip-composite mold. At the same time, the use of reference materials in the design to determine the size of the working parts. And more to consider the restructuring of the mold, and easy to replace and the cost of mold. At the same time, the contents of the mold design stamping die in a combination of different processing methods, processing technology and assembly process, stamping die mold for novice designers have a certain reference value. The design of the parts from the mold design process and the assembly process, such as described in detail, and the application of CAD for the design of the important parts. Intending is bring the flange parts of the tube, choose a suitable blank holder force is extremely important, it should be specific to ensure that the premise of not wrinkling take the minimum. Discharge before blanking plate in the binder and role play. By the convexity of the composite mold touch with blanking blanking die for deep drawing process, after the punching process. In addition, the work of layout sheet utili
