批量较小且材料较厚而凸模强度大时 可采用固定导板导向 即采用固定 导板模 c 冲件形状复杂 精度较高 且为中 大批生产时用导柱 导套导向 此种导向生产中常用 导柱导套有滑动导向和滚动导向两种 一般都用滑动导向 只有冲件精度很高时才选用滚动导向 d 冲件孔小 凸模多且强度弱时用弹压导板导向 B 复合工序模 复合工序模 复合模都有导向 C 级进模 级进模 选择方法与单工序模的 b c d 三项相同 3 滑动式模架选择 无导向和用固定导板导向的模具及用导柱 导套导向和弹压导板导向的模具 一般都有标准模架 用导柱 导套导向的模架 随导柱位置的不同又有如下几种 可根据需要选择 A 对角导柱模架 可以承受一定的偏裁 上下动作平稳 且能纵横两方面送料 用于有偏载的大中型模具 B 后侧导柱模架 可以三方面送料 操作特别方便 受力均为偏载 模架容易变形 一般用于受力不大或 精度要求不高的中小型模具 C 中间导柱模架 结构简单 加工方便 但只能一个方向送料 当受偏裁时 模架也有变形 D 四角导柱模架 滑动平稳 导向准确 用于冲件精度较高的大型冲压模具 4 压 卸料方式的确定 冲件平整度要求较高或料较薄时 用弹压卸料板 它既可压料 又可卸料 因卸料板随上模上下运 动 送料直观性强 操作方便 这是生产中常用的一种卸料方式 当料较厚 用弹压卸料难以卸件 或零件形状简单 要求不高时采用固定卸料 它可简化模具结构 但因行腔封闭 送料只能靠手感 操作不便 安全性差 5 定距方式的确定 对单工序模具且单排排样 一般用挡料钉定位即可 若用双排且需调头送料的有时要用挡料钉和伸 缩挡料销结合使用 对复合工序模中的顺装复合模 一般用固定挡料销定距 对倒装复合模 若挡料销在凹模上的让位 孔离凹模型腔较远时用固定挡料销 若挡料销让位孔离凹模型腔太近时 则要用伸缩挡料销 以免削弱 凹模强度 对级进模 其定距方式有始用挡料加固定挡料定距 侧刃定距两种方式 若跳步步数较少 1 2 个 且料厚时 可用始用挡料加固定挡料 跳步步数较多的则用侧刃定距 从侧刃定距方便容易实现自动化 送料的角度 侧刃定距在现代生产的级进模中用得越来越多 若尺寸要求较高 可在以上两种定距方式 中增加导正销 提高定距精度 4 4 根据模具类型画排样图 并计算材料利用率 根据模具类型画排样图 并计算材料利用率 画排样图是极为重要且技术性很强的设计工作 排样图的合理与否直接影响到材料的利用率 零件 质量 生产率与成本 以及模具的结构与寿命等 yuan an increase of 17 5 local government general budget revenue of 500 million Yuan Painting model culture creates new Ma Church
