滚 轮 支 架 冲 压 工 艺 与 模 具 设 计摘 要本论文以滚轮支架为例，在分析了该零件的加工难点后，考虑了几种可行的成形方案。在分析之后，选择了落料冲孔复合，弯曲单工序模的工艺方案。该模具主要工序包括：落料、冲孔，最后弯曲，保证了生产效率以及模具制造的简单、低成本。该模具结构简单灵活、可靠，并能保证产品质量，成本低，对此类零件的复合模设计有重要参考价值。通过本论文我掌握了模具设计的基本技能，懂得了怎样分析零件的工艺性和怎样确定工艺方案，并且了解了模具的基本结构，提高了计算能力，绘图能力，熟悉了模具设计的规范和标准，同时对各个相关的课程都进行了全面的复习。而且我独立思考的能力也有了提高。关键词：滚轮支架, 成形工艺, 落料冲孔复合, 弯曲, 模具结构ROLLING WHEEL HOLDER PUNCHING TECHNOLOGICAL AND DIE OF DEVISEABSTRACTTaking a rolling wheel holder belt pulley as an example, the forming difficulties of the part were analyzed, and five feasible stamping were put forward. Through comparison, process 4 was selected because it had less process steps, more compound processes, and it also could ensure the precision and coaxiality of the part. Principal manufacturing processes, including: blanking, punching, drawing, anti-drawing. The stamping die structure was presented according to process 4. The die was very simple in structure and could reduce process steps and improve efficiency. Practice has proved: the structure of die is flexible, reliable and can ensure product quality and low cost, it can be important reference to the design of progressive die for such parts. Through this paper we master die design of the basic skills to understand the mold of what parts of the process, how to determine Process, learn the basic structure of the mold, improved computing power, graphics capabilities, and is familiar with the norms and standards related to curriculum subjects at the same time have a compr...
