汽车前桥支架座冲压工艺及模具设计(选题审批表,任务书,开题报告,中期检查表,论文说明书12600字,CAD图11张)
摘要：模具设计是机械专业一个最重要的教学环节,是一门实践性很强的学科，是我们对所学知识的综合运用，通过对专业知识的综合运用，使学生对模具从设计到制造的过程有个基本上的了解，为以后的工作及进一步学习深造打下了坚实的基础
本文介绍的模具实例结构简单实用，使用方便可靠，首先根据工件图算工件的展开尺寸，在根据展开尺寸算该零件的压力中心，材料利用率，画排样图。根据零件的几何形状要求和尺寸的分析，采用复合模冲压，这样有利于提高生产效率，模具设计和制造也相对于简单。当所有的参数计算完后，对磨具的装配方案，对主要零件的设计和装配要求技术要求都进行了分析在设计过程中除了设计说明书外，还包括模具的装配图，非标准零件的零件图，工件的加工工艺卡片，工艺规程卡片，非标准零件的加工工艺过程卡片。

Stamping Process and Die Design of Bracket Seat of Front Axle in the Automobile
Abstract: Mold design is one of the most important mechanical professional teaching link, is a door practice-needed curriculum, is we to the knowledge of the comprehensive utilization, through the comprehensive use of professional knowledge, enables the student to the mold from design to manufacturing process have a basically understanding for the future work and further study to lay a solid foundation .
This paper introduces the mould structure is simple, practical, and use examples convenient and reliable, first of all, according to the workpiece development size of workpiece figure is in development size, according to calculate the parts of pressure center, material utilization, painting the strip layout diagram. According to the geometrical shape parts requirements and size analysis, using composite modulus stamping, it helps improve the production efficiency, mould design and manufacture also relative to the simple. When all the parameters are calculated to mold after assembly scheme of main parts, the design and assembly required technical requirements are analyzed in the design process in addition to the design specification outside, still include mould assembly drawings, non-standard parts graph, the processing technology of the workpiece, process planning CARDS, CARDS non-standard parts processing process card.
