冷凝器侧板工艺分析及模具设计 摘 要 本设计的任务是冷凝器侧板冲压模具设计，文中从工艺设计与模具设计两方面对制件进行了分析和讨论，并设计出了落料冲孔模，翻边弯曲模两套模具。 首先，根据产品图分析了冲压件的形状特点、尺寸大小、精度要求、材料力学性能，并结合模具制造条件、生产批量等因素，分析了零件的冲压工艺性。在工艺性分析的基础上，提出了各种的可能的冲压工艺方案，并通过分析比较确定出适合于现有生产条件的最佳方案。接着，进行了诸如零件展开尺寸、材料利用率、冲裁力、拉深力等主要工艺参数计算。根据计算结果选出了合适的冲压设备并确定了模具压力中心。 其次，根据拟订的工艺方案，分别确定了落料冲孔、翻边弯曲模具结构型式。然后，计算或校核模具结构上的有关参数，如模具工作部分尺寸、模具零件的强度和刚度、模具部件之间的配合与公差等。 关键词：冷凝器侧板，冲压，落料冲孔模，翻边弯曲模，工艺分析，模具设计 Analysis nd Die Design To Condensers Side Bar ABSTRACT The task of this design is condensers side bar stamping die design. In this paper, process design and die design on the two parts are analyzed and discussed，and designed two sets of drawing punching die and flanging bending die. First of all,According to the product chart, has analyzed pressing parts shape characteristic , size, precision, mechanical properties. combined with the conditions of mold manufacturing, production volume and other factors, an analysis of parts of the stamping process. In the technological analysiss foundation, proposed some possible ramming craft plan, and through the analysis comparison, determined suits in the existing working condition preferred plan. Then, carried on such as the launch size, material usage rate, the blanking force, the drawing strength and so on main technological parameter computation. According to the computed result, has selected the appropriate ramming equipment and determined the mold center of pressure. Next, according to the craft plan which drafts, has determined drawing punching, the flanging bending mold structure pattern separately. Then, computation or in examination mold structure related parameter, like mold effective range size, mold components intensity and rigidity, Coordination and common difference between the mold parts and so on. KEY WORDS: condensers side bar, stamping, drawing punching die, flanging bending die, process analysis, mold design 目 录 1 第一章 工件的冲压工艺分析 4 §1.1 设计题目 4 §1.2 工件的材料分析 5 §1.3 工件的加工可行性分析 5 第二章 数据计算及工序确定 6 §2.1 毛坯尺寸计算 6 §2.2
