摘要
本次设计是在冲压模具设计过程中结合生产实际，首先研究冲压成形的基本理论,然后运用基本理论对该制件的基本工序的特点、性质、规律进行了分析、研究和探讨。以冲孔、落料、弯曲工序为重点确定冲压工艺方案, 在工艺分析的基础上提出几种可行的工艺方案，用技术经济分析方法确定了最佳工艺方案，进行了工序的组合。在制件的整体结构的设计中，还要进行模具中各个零件的设计及选择和某些零件相关尺寸的计算及校核，如确定凹模尺寸、凸模尺寸，确定凸、凹模的结构形式，并对其进行强度校核。然后是模具的零件设计，主要是导柱、导套的设计选择，卸料板的选择及其厚度的确定，固定板的尺寸确定。确定模具上下模座的形式及其厚度。
在冲孔、落料、弯曲级进模具的设计过程中，我收集了大量的材料去研究冲模的设计过程，参考了大量的关于冲压模设计及冲压工艺的书籍和技术资料，研究本冲压模设计的每一个要点，对每一个零件的设计都验证了其合理性，刻苦钻研复合模设计的过程，及时发现问题并找指导老师解决。在设计本模具的过程中我对模架的强度，需加的垫板，弹簧的力与卸料力的比较都进行了相应的计算选择和校核。另外在生产条件下进行了验证，保证了该工艺的可行性，为缩短产品生产周期、节省原材料及大批量生产创造了条件。对此次设计的设计要点，本文进行了以下几方面研究：
1.应用绘图软件AutoCAD进行零部件设计，减少了试模次数，提高了生产效率，节省成本；
2.本次设计的模具采用了冲孔落料弯曲级进模，节省人力，节省了工序，从真正意义上实现高效率的生产；
3.本次的设计结果是可行的，可以在具体生产中应用；
4.通过计算，凸模要加上垫板增加其强度
5.考虑了刃口的增减性，在进行冲压时，凸模刃口尺寸减小，凹模刃口尺寸增大。冲裁间隙选用最小合理间隙

Abstract
The stamping design is combined with producing reality ,I resesrched the process with the fundamental theory first,then studied working procedure with priority while ascertaining the stamping scheme on the industrial analysis basis, used technical analysis method to ascertain the best scheme, carried out the combination with working procedure. After that, I selected the pulling deep forming ,designed entire structure. And then the mould part design,including guide pin.I ascertained the material board and their thickness, the dead plate dimension , the person fixes about unnatural thickness , model seat form and their thickness.
In the design process of pulling depths ,I searched large amount of books and technical data of designing and stamping a model ,collected large amount of material and references. I have studied every essential part in this compound stamping model design , verified the rationality to every part design , dug into the process of the compound model design assiduously , discovered every problem in time and looked for a teacher explain that.In this process I studied the intensity of the mould designing capital to the model , the need of adding backing board,how to choose spring force and proofread with removing the calculation, expected that the force comparison has all carried out with more advantages.I have carried out verification under producing condition , ensured the handicraft feasibility’s turn to shorten the production cycle , to make full use of raw material . Several aspects of designing that essential main body has carried out and the main part of designing are following:
- I appliedthe designing software AutoCAD intothe progress of designing components,this has decreased the number of times of experimenting model , improved efficiency, minimized cost;
- The mould design has economized manpower , workingprocedure ,realized high efficiency with high significance;
- The design result is feasible , canbeapplied into real production;
- Increasedwhose intensity by adding protruding model with backing board
- When stampingare carriedout ,the adding or subtracting of a cutting edge dimension should be considered. I selected and used the minimal rational gap according to cutting a gap.
