扬声器内磁盖模具设计

第一章绪论

随着我国汽车、摩托车、家电等工业的迅速发展，工业产品的外形在满足性

能要求的同时，变得越来越复杂，而这些产品的制造离不开模具，这就要求模

具制造行业以最快的速度、最低的成本、最高的质量生产出模具。为了达到上述

要求，模具企业只有运用先进的管理手段和 CAD/CAM 集成制造技术，才能在

激烈的市场竞争中立于不败之地。

模具可以分为多种,如注塑模、冲压模等，随着制造工艺和塑料性价比的提高

冷冲模具在模具行业中占的比重越来越大，，本研究讨论的是一个喇叭磁盖模

具设计的冷冲模具设计，在这过程中充分展示了计算机辅助建模和制造为模具

的集成制造提供了优良的平台。

第二章冲压工艺分析与确定

2．1冲压件工艺性分析

此工件有落料、冲孔、拉深三个工序，材料为 Q235-A 钢，具有良好的冲压性

能，适合冲裁、拉深，工件结构简单，有 6个φ4mm 的孔，孔与孔、孔与边缘之

间的距离也满足要求；该工件属于较典型圆筒形件拉深，形状简单对称，所有

尺寸均为自由公差，对工件厚度变化也没有作要求。

2．2冲压工艺方案的确定

该工件包括落料、冲孔、拉深三个工序，可有以下三种工艺方案:

方案一: 先落料，后冲孔，最后拉深。采用单工序模生产。

方案二: 先落料－冲孔复合冲压，后拉深。采用复合模和单工序模生产。

方案三: 落料－冲孔－拉深级进冲压。采用级进模生产。

方案一模具结构简单，但需三道工序三副模具，成本高而生产效率低，

以满足中批量生产要求，零件的尺寸和形状不精确，且存在工序分散，劳动

量大，占用设备多。方案二需两道模具，工件的精度及生产效率都较高，满
