I 毕业设计论文毕业设计题目: 摩托车车架冲压件模具设计学院西安机电信息学院专业机电工程系班级 09 高模一班学号学生姓名指导教师完成日期 2011 年 10月 II 摩托车架冲压件模具设计摘要本设计主要对摩托车车架部分冲压件模具进行了设计。摩托车车架是摩托车的主要承载部件,其强度和疲劳寿命对摩托车整车来说至关重要,传统的设计方法,一般是先进行结构功能设计,再试制样机,然后检验车架的静、动态特性,如不能达到设计要求,需重新设计、试制样机和试验,如此循环往复,这一过程周期长,以一新型运动型多功能休闲摩托车车架为研究对象,对车架结构进行了分析。得出了最佳加工方案,在充分保证零件质量与精度的前提下,选择高生产率的加工工艺,降低生产成本,从而有效地节约了材料。本设计中使用计算机软件进行了辅助设计,在保证高精度的同时简化了传统的繁琐计算过程,使设计更为便捷。该转向锁零件从坯料到完全成形,共用到两套模具:冲孔落料复合模与弯曲模。所设计的两套模具较为典型,也具有一定的代表性。本设计的重点与难点是对凸、凹模刃口尺寸的计算,因为它将直接影响零件的质量。关键词冲压模具;复合模;辅助设计;模具结构 III Abstract The design mainly studies the s tamping die for the nog of turning lock, 7702- motorcycle. Unite the actual production requirements and product characteristics of Great River Corporation, under the original design of the factory, carries on the innovative design to the die. The design carr ies on the craft analysis to the nog of turning lock , obtains the best working scheme. In the full guarantee of ponent ’s quality and the precision, of reducing the production cost , the high productivity processing craft is choose n. The design use s puter-aided design software to ensure high-precision while simplifying the calculation of traditional and cumbersome process to simplify the design. The nog of turning lock from the blanks plete forming has two sets of mold aggregately: the punching - pound die and the bending die. The two sets of molds are typical and have certain representation s. The keystone and nodus of this design are the account of the knife-edge of the protrude die and the concave die as it would aflect the quality of the accessory straightly.
