多工位_级进模_毕业论文.doc

摘 要 模具是工业生产中重要的工艺装备，是国民经济各部门发展的重要基础之一。而作为冷冲模中一种的级进模，更是在当今模具生产中起到了极其重要的重用。级进模是指模具上沿被冲原材料的直接送进方向，具有两个或两个以上的工位，并在压力的一次行程中，完成两个或两个以上冲压工序的冲模。多工位级进模具有高效、高精度、长寿命的特点，它以成为实现大生产，降低生产成本的最佳选择，是当代先进模具的代表。 所以本文以复印机上的板簧为例，经工件的工艺分析计算、工位安排、排样设计，最后的设计出整套模具结构并绘制了模具的装配图和零件图。重点介绍了条料的导向、滑块弯曲成形的结构及压缩空气吹件装置。 另外，对于板料成形而言，DYNAFOEM软件已成为板料成形数值模拟的专用软件，已是当今流行的板料成形与模具设计的重要工具之一。所以，还针对圆筒形件的拉深情况用DYNAFOEM软件进行了数值模拟分析，并对最后的结果进行了分析与比较，确定出适合的参数。 关键词：多工位级进模 板料成形 数值模拟 拉深 板簧  ABSTRACT Mould Die is important technical equipment in industrial production. It is also one of the most important developmental foundations for all departments of country economy.。Progressive Die is one kind of the die , and it has played an extremely important part in todays mold production . Progressive Die is that along the raw materials are washed directly into the direction ,it has two or more work spaces, and under the pressure of a program, completes two or more die stamping processes. Multi-position progressive die are high-performance, high-precision, long-life characteristics, which become large-scale production, lower production costs the best choice is to die on behalf of contemporary art. The paper takes a type of stainless leaf spring in digital duplicator foe example. and design a die of the leaf spring by the analysis of the workpiece, the arrangement and layout design.. Besides, the paper focuses on the expected direction, the slider structure and bending pieces of compressed air blowing device. In addition, in terms of sheet metal forming, DYNAFOEM software has become a numerical simulation of sheet metal forming special software is popular in todays sheet metal forming and die design one of the important tools. Therefore, in view of the cylindrical pieces of the situation by drawing DYNAFOEM numerical simulation software analysis, and final results are analyzed and compared to determine the suitable parameters.
