侧板落料冲孔复合模设计
摘要
随着中国工业不断地发展，模具行业也显得越来越重要。本文针对侧板的冲裁工艺性，介绍了落料冲孔复合模设计加工方法。分析比较了成形过程的三种不同冲压工艺（单工序、复合工序和连续工序），确定用一幅复合模完成落料冲孔的工序过程。基本的要求是模具应能满足加工要求，保证制件精度；模具应运转平稳，工作可靠，结构简单，装卸方便，便于维修和调整；模具尽量用通用件以便降低制造成本。
本课题主要是冲压成型的工艺设计，也就是冲压模的工艺设计方案分析及确定工艺计算和模具结构设计计算等内容，且简要分析了坯料形状、尺寸，排样、裁板方案和冲压工序性质。进行了工艺力、压力中心、模具工作部分尺寸及公差的计算，并设计出模具。还具体分析了模具的主要零部件（如凸凹模、卸料装置、垫板、凸模固定板等）的设计与制造，冲压设备的选用等。列出了模具所需零件的详细清单，并给出了合理的装配图。为了提高生产效率，因此在设计时要力求结构简单，但是一定要保证其精度要求。在对制件分析的基础上完成了整副模具的设计，用CAXA软件完成了二维设计图纸的绘制,制件、模具零部件造型全部用SolidWorks2007软件完成同时考虑了零部件的加工。

Abstract
With China's industries continue to develop and die industry is also becoming increasingly important. Based on the side plate of the stamping process, introduced the blanking punch compound die design and processing methods. Comparative analysis of the process of forming three different stamping process(single processes, complex processes and continuous processes), confirm completion of a composite model blanking and punching process. The basic requirement is mould should be able to satisfy the requirements of the processing, guarantee product precision; mould should be smooth operation, reliable, simple structure, easy maintenance, loading and unloading easily, convenient service and adjustment; mold as far as possible in order to reduce the use of common parts manufacturing costs.
This subject mainly stamping forming process design, also is the stamping mould design analysis and calculation, the mould structure determination technology design, etc, and a brief analysis of the blank shape, size, layout, cutting board and pressing nature of the process program. For the process, the center of pressure, the die size and the tolerance of the calculation, design mold. Also analyzes the mold of the main components(such as punch and die and dump devices, slates, punch plate, etc) design and manufacturing, stamping equipment selection, punch-gap adjustment and establishment of avital parts machining process. Die requirements set out a detailed list of parts, and gives a reasonable assembly. Production is mainly in order to increase the production efficiency, thus in the design of simple structure, but should strive to ensure the accuracy of certain requirements. Based on the analyses of manufacture, completion of the entire mold design, completewith CAXA software drawing two-dimensional design drawings. and all of the manufactures, subassemblywere sculpted by Solidwork2007 software.
