内容简介：

焊片冲孔落料弯曲模设计 摘 要本设计题目为中焊片冲孔落料弯曲模设计。通过对该零件模具的设计，进一步加强了设计者冲孔落料弯曲模设计的基础知识，为设计更复杂的冲压模具做好了铺垫和吸取了更深刻的经验。本设计运用冲压成型工艺及模具设计的基础知识，介绍了模具设计时要注意的要点，并较多的考虑了模具结构的调整性、易更换性及模具成本。从控制制件尺寸精度出发，对外壳冲孔切边模的各主要尺寸进行了理论计算，以确定各工作零件的尺寸，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。关键词：冲孔，落料，弯曲模 工艺分析 模具结构 The design of punching，bending and blanking die of Soldering Flake AbstractThe design the topic for the Design of the Trimming Die punching shell. The designers foundation knowledge is reinforced and is able to design more complex press die through the design. The design of the use of punch forming process and die design of the basic knowledge on the mold design to the main points of attention and more consideration of the mold structure, and easy to replace and the cost of mold. Size precision parts from the control point on the shell punching die trimming the size of all the major theoretical calculations carried out to determine the size of the working parts, the parts from the mold design process and the assembly process in detail, etc., and the application of CAD for the design of the important parts.
