1、 【摘要摘要】 ：本课题是热水器壁挂支架的级进模具。热水器壁挂支架的级进模具包括冲裁、弯曲及压 筋等工艺步骤，其中冲裁包括冲孔与落料。热水器壁挂支架采用侧刃定距的定位方式，能够准确对 条料进行定距； 送卸料方式是通过人工送料和弹性卸料来实现的。 由于级进模模具的定位精度要求 较高，因而用了四导柱的定位方式。模具的主体采用了整体结构，凸凹通过配合加工来满足凸凹模 之间的精度要求。模具的凸模定位方式采用了台阶式结构。该模具的设计过程：先通过工艺分析确 定了工件的排样图（其中包含：工艺步骤的划分，条料的定距方式，凸凹模的形状等）,通过排样 图确定凸凹模的尺寸，计算凸凹模的刃口尺寸，利用 AUTOCA
2、D 绘制出凸凹模的二维图，再运用 UG 绘制出模具各部分的三维模型，按照要求用 UG 对模具各零部件进行装配，从而得到模具总装图。 【关键词关键词】 ：热水器壁挂支架；级进模具；定位；精度 【Abstract】: The issue is water heater wall mount bracket for progressive die.Heater wall bracket progressive die including punching, bending and beading and other process steps, which include punching and
