磁保持继电器 BMD-1HD 衔铁冷冲模设计
摘要
首先，本文根据我国的国内市场的实际情况，对冲压技术在当今
社会的发展前景和地位进行了深入分析，对模具在实际使用中需要改
进和借鉴的地方进行了分析。在此基础上，本文进行总结，得出了几
点意见。第一就是要对所研究的课题进行研究分析，在分析的过程中
需要找出模具的加工方向，选用符合精度要求的特定材料。第二，在
此基础上，完成级进模的总体结构方案，首先就是确定模具的工艺类
型，然后结合实际的生产条件和需求来确定制件的操作模式，依据生
产过程的技术水平来确认出件方式和卸料方式。确认了模具的整体结
构方案之后，开始计算级进模的工艺，完成计算之后设计及选择模具
的整体结构零件。
本课题的结论就是在对零件进行工艺性分析的基础上，判定制件
为为级进模，依据此结论可知工件拥有优良的精度和平整度。在此过
程中，我们需要分析工件的冲裁工艺，本课题使用的是正装式级进模，
使用自动送料技术，同时使用弹压卸料方式以保证产品的质量。制件
以上出件作为出件方式，但是为了解决废料的遗留问题，实际操作中
需要采用下出件方式进行生产。
初选压力机的依据是对压力中心的计算结果，通过对计算结果的
研究比对，确认初选的压力机，再对凹模，凸模的刃口尺寸进行计算，
因为冲裁件的主要部分的尺寸精度的确认基于对凸模，凹模的刃口尺
寸以及尺寸公差进行计算，模具的合理间隙也是靠刃口的尺寸及尺寸
公差来保证模具总装零件图的绘制。
本课题提出的级进模设计方案，以模具的设计与制作来看还是有
着很大的不足之处，例如实际操作中大多数企业采用的还是半自动操
作，如果想要发展好模具制作产业就要不断的优化生产技术，提高生
产效率，降低生产成本，减少材料损耗，尽可能的采取全自动化生产
线以降低半自动乃至于人工操作带来的失误率及废品率。按照我国目
前的实际发展情况来看，本课题的研究内容仍然具有相当的参考价值
和一定的使用价值，完全可以在某些研究进行的时候作为参考资料使
用。

Abstract
Firstly, according to the actual situation of domestic
market, this paper deeply analyzed the development
prospects and status of stamping technology in today's
society, and analyzed the areas needing improvement and
reference in the actual use of dies. On this basis, this
paper summarizes and draws some opinions. The first is to
study and analyze the subject studied. In the process of
analysis, it is necessary to find out the direction of die
processing and select specific materials that meet the
accuracy requirements. Secondly, on this basis, the
overall structure of progressive die is completed. Firstly,
the process type of the die is determined, then the
operation mode of the part is determined according to the
actual production conditions and requirements, and the
part mode and unloading mode are confirmed according to the
technical level of the production process. After
confirming the overall structure of the die, the process
of the progressive die is calculated, and the overall
structural parts of the die are designed and selected after
the calculation. The conclusion of this subject is to judge
the part as progressive die on the basis of process analysis.
According to this conclusion, we can know that the part has
excellent precision and smoothness. In this process, we
need to analyze the blanking process of the workpiece. This
topic uses the forward progressive die, the automatic
feeding technology, and the elastic pressure unloading
method to ensure the quality of the product. In order to
solve the problem of waste residue, it is necessary to adopt
the following production mode in actual operation. The
basis of the primary press is the calculation result of the
pressure center. Through the research and comparison of the
calculation results, it confirms the primary press, andthen calculates the edge size of the die and punch. Because
the confirmation of the dimension accuracy of the main
parts of the blanking parts is based on the calculation of
the punch, the edge size of the die and the dimension
tolerance, and the reasonable clearance of the die is also
the size of the edge. And dimension tolerance to ensure the
drawing of die assembly parts. The design scheme of
progressive die put forward by this subject still has great
shortcomings in terms of the design and manufacture of die.
For example, most enterprises adopt semi-automatic
operation in practical operation. If we want to develop the
die manufacturing industry well, we must constantly
optimize production technology, improve production
efficiency, reduce production costs, reduce material
losses, and adopt full automation as far as possible.
Production line to reduce semi-automatic and even manual
operation of the error rate and scrap rate. According to
the actual development of our country at present, the
research content of this topic still has considerable
reference value and one. The definite use value
can be used as a reference for some studies. Key
