调节器附件 2 冲压模具设计
摘要
这次的说明书主要从以下几个方面进行论述。冲压变形中每个步骤的详细讲
解，冲裁部件尺寸的计算，凸模和凹模刃口尺寸计算，冲裁力大小，压力中心计
算，排样设计，整套模具的结构设计，推件装置的设计，成型零部件结构设计，
模具标准件的选用，选择合适的压力机等等。最后还要探讨下冲压模具经常出现
故障的问题点以及分析它的原因。这篇说明书中的每个篇章每个章节都是对自己
设计的冲压复合模具的详细讲解，在说明的时候还加入了图片和表格，丰富说明
内容，加强说服力，是整片文章更有亮点和看点。这次的产品是调节器附件二，
是机械装备上的零部件，猜想是通过安装它来调节整体的厚度和高度的。所以外
形尺寸很重要，太大了会卡住装不进去，太小了会松弛在机器工作过程中会不稳
定，左右晃动，时间长了甚至起到了消极的影响。这次设计的是冲压复合模具，
是冲压模具类型中较为常用的，能够保证产品形状之间的相对位置的尺寸达到要
求，成本比级进模低，精度比单工序冲压模具高。

第一章褚论
1.1 冲压工艺介绍
冲压加工是改变金属产品形状的加工方法，是利用安装在压力机上的模具对
板材施加压力，在常温下改变其形状或分离的一种加工方法。产品具有尺寸精度
高，形状完整，生产效率高的特点。在机械加工中是一种高效率的加工方式。最
常见的是将一个平面的金属板变成立体的，冲压产品广泛的用于各个行业中，大
到航空航天，军事科技，轮船火箭，小到医疗器械，食用的餐具，量具内的零件。
都要用到冲压加工，所以在生活中无处不在，随处可见。
冲压工艺有以下几个特点：1.冲压件表面不粗糙，质量轻，强度好。2.能生
产复杂的产品，具有其他加工设备在绩效比上没法比拟的优势，像这样小型的产
品，一分钟可以生产四五个。3.模具制造精度高，冲压件质量稳定，尺寸符合精
度要求，所以冲压件质量过关，互换性强。4.材料利用率高，一般要在 50%以上
5.操作简单，经过短期培训后的工人可以上岗任职。现在传送料带的装置用的自
动送料的比较多，易于实现机械化和自动化生产。6.对于冲压模具设计师的要求
较高，一副模具的好坏的源头在于设计，设计者要有理论和实践相结合的检验，
要有很强的想象力和与创造力。 7.小批量且要求交货时间急促的产品不适合冲压
模具生产，因为模具成本高，制造周期长。8.由于是滑块上下闭合运动来生产产
品，存在很大的安全风险，手工操作时劳动强度大，
