本文利用PROE进行饮料瓶的三维结构设计，这个模型必须使用曲面造型才能完成设计任务，在日常的模具产品设计中，曲面设计也是必不可少的。

CAXA制造工程师习题(塑料瓶底画法)

-第13章综合实例13.1可乐瓶底的造型和加工13.1.1 凹模型腔的造型13.1.1.1造型方法分析可乐瓶底的表面主要由曲面构成，造型比较复杂。

由于直接用实体造型不能完成，所以先利用CAXA 制造工程师强大的曲面造型功能做出曲面，再利用曲面裁剪除料生成凹模型腔。

可乐瓶底的侧表面可以用网格面来生成，因为是由图6-30可乐瓶底曲面造型的二维图图6-29可乐瓶底曲面造型和凹模型腔造型五个完全相同的部分组成的，我们只要作出一个突起的两根截面线和一个凹进的一根截面线，然后进行环形阵列就可以得到其他几个突起和凹进的所有截面线，最后使用网格面功能生成曲面。

可乐瓶底的最下面的平面我们使用直纹面中的--“点＋曲线”方式来做，这样做的好处是在做加工时两张面（直纹面和网格面）可以一同用参数线加工。

最后以瓶底的上口为准，构造一个立方体实体，然后用可乐瓶底的两张面把不需要的部分裁剪掉，就可以得到我们要求的凹模型腔。

13.2.1.2绘制截面线1．按下“F7”键将绘图平面切换到XOZ 平面。

2．单击“矩形”按钮，在立即菜单中选择“中心_长_宽”方式，输入长度42.5，宽度37，输入（21.25，0，-18.5）为中心点，绘制一个42.5×37的矩形。

如图6-31所示 3．单击“等距线”按钮，在立即菜单中输入距离3，拾取矩形的最上面一条边，选择向下箭头为等距方向，生成距离为3的等距线。

相同的等距方法，生成如图所示尺寸标注的各个等距线，如图6-32所示。

4．单击“裁剪”按钮，拾取需要裁剪的线段，然后单击“删除”按钮，拾取需要删除的直线，按右键确认删除，结果如图6-33所示。

5．作过P1、P2点且与直线L1相切的圆弧。

单击 “圆弧图6-31矩形图6-32等距线图6-33 删除结果-”按钮，选择“两点_半径”方式，拾取P1点和P2点，然后按空格键在弹出的点工具菜单中选择“切点”命令，拾取直线L1。

6．作过P4点且与直线L2相切，半径为6的圆R6。

CATIA实操瓶子的设计方法

CATIA实操瓶子的设计方法在工业设计领域，CATIA 是一款功能强大的软件，能够帮助设计师实现各种复杂的设计构想。

今天，我们就来详细探讨一下如何使用CATIA 来设计一个瓶子。

首先，打开 CATIA 软件，新建一个零件文件。

在开始设计之前，我们需要明确瓶子的设计要求，比如瓶子的用途（是用于盛装液体还是固体）、容量大小、外观风格（简约、时尚、复古等）、材质（玻璃、塑料、金属等）以及生产工艺（吹塑、注塑、压铸等）。

假设我们要设计一个用于盛装饮料的塑料瓶，容量为 500 毫升，外观简约时尚。

第一步，绘制瓶子的轮廓草图。

选择“草图”工具，在基准平面上绘制瓶子的大致轮廓。

可以先画出一个长方形，作为瓶子的主体部分，然后在长方形的上方和下方分别绘制出弧形，以形成瓶颈和瓶底的初步形状。

注意，在绘制草图时，要合理使用约束工具，确保线条之间的位置和尺寸关系准确无误。

第二步，对草图进行拉伸操作。

选中绘制好的草图，选择“拉伸”工具，输入合适的拉伸长度，从而得到瓶子的初步实体模型。

接下来，对瓶子的瓶颈部分进行细化设计。

再次进入草图模式，在瓶颈处绘制新的草图，如螺纹或者防滑纹理等。

完成草图后，进行相应的特征操作，如旋转、扫掠等，以实现所需的效果。

瓶底的设计也不容忽视。

同样通过草图和特征操作，为瓶底设计出合适的形状，比如平底、凹底或者凸底，并考虑其稳定性和受力情况。

在设计过程中，要时刻关注瓶子的整体比例和对称性。

可以使用CATIA 中的“测量”工具，测量瓶子各部分的尺寸和角度，确保符合设计要求。

然后，对瓶子的表面进行处理。

如果想要瓶子表面呈现出光滑的效果，可以使用“曲面拟合”工具；如果希望有磨砂质感，则可以通过添加纹理或使用“布尔运算”来实现。

此外，还可以为瓶子添加一些装饰元素，如品牌标志、图案等。

这可以通过在瓶身表面绘制草图，然后进行浮雕或刻蚀等操作来完成。

当瓶子的主体设计完成后，不要忘记对其进行装配检查。

将瓶子放入虚拟的包装环境中，查看其与其他部件的配合是否良好，是否存在干涉等问题。
