自行车脚蹬内板零件的冲压工艺及模具设计.docVIP

自行车脚蹬内板零件的冲压工艺及模具设计 摘 要 本次毕业设计是在我们完成所有基础课和专业课以及课程设计的基础上开设的比较重要的教学实践环节，是对我们大学所学课程的巩固和重新认识，相信通过本次毕业设计，我们的水平可以有一定的提高。需要完成的主要工作有：对所给零件进行工艺性分析并确定合理的冲压工艺方案、进行有关工艺与设计计算、确定模具结构的设计及定位方式的选择、绘制零件的二维装配图并用三维软件进行运动仿真以验证和分析模具的工作过程。 本次毕业设计是冲孔翻边落料级进模的设计，冲压模具主要是将板料分离或成形而得到制件的加工方法。因为模具的生产主要是大批量的生产，而且模具可以保证冲压产品的尺寸精度和产品质量，模具的设计与制造主要考虑到模具的设计能否满足工件的工艺性设计，能否加工出合格的零件，以及后来的维修和存放是否合理等。在本次设计中的自行车脚蹬内板中，不仅要考虑做出的零件能否满足工作要求，还要保证它的使用寿命。 其次设计中还要考虑到它的实际工作环境和必须完成的设计任务，模架采用对角型模架，凹模采用组合凹模，这样可以采用线切割等数控设备来一次完成全部的工序加工，在设计中还要考虑到很多关于所设计模具的相关知识，包括它的使用场合、外观要求等，从这里可以知道模具设计是一项相对复杂的工作，所以在设计要不断的改进直到符合要求。 关键词?：翻边； 工艺性 ；级进模 Bicycle pedal within the board parts stamping process and die design Abstract The quite important teaching practice link which this graduation project is completes all basic courses and the professional course as well as the curriculum in us which design in the foundation opens, is studies the curriculum to our university consolidated and knew, believed through this graduation project, our level may have certain enhancement. Needs to complete the prime task includes: To carries on the technology capability to the components to analyze and to determine the reasonable ramming craft plan, carries on the related craft and the design calculation, the determination mold structure design and the locate mode choice, the plan components two-dimensional assembly drawing and carries on the movement simulation with the three dimensional software to confirm and to analyze the mold the work process. This graduation is piercing flanging blanking progressive die design, stamping die mainly forming sheet metal separation or get parts of processing method. Because mold production mainly for high-volume production, and mould can guarantee press products for dimensional accuracy and quality of products, tooling design and manufacture of major design can meet the work-piece process design, whether processing quality parts and later maintenance and hosting is reasonable. In this design bike pedal inner panel, not
