带孔弯曲件的冷冲模设计
摘要

随着中国制造业的发展，模具行业也得到了快速的发展和更广泛的应用。本文针对带孔弯曲件的模具设计，介绍了连续模的设计方法和步骤，分析、比较了三种类型模具（单工序模，连续模，复合模）的优缺点，同时，确定了带孔弯曲件的制造工序和模具选用的最佳方案。设计的方法和步骤主要从工件的各项性能，工件的成型工序，模具的各部件设计，模具的强度校核及模具的制造工艺等几个方面入手。
本次设计的难点主要在于加工工序的安排，如何保证模具的可靠性和精度，设计出的模具符合工厂现有条件下进行生产，并最大限度的降低劳动强度，提高生产效率。模具的设计过程中，包含了工件的排样，凹模凸模、卸料装置、凸模固定板等主要模具零部件的设计制造。在对整副模具完成设计后，按技术要求画出模具的三维造型和二维图纸。

Abstract

with the transition of China, from a manufacturing power to a creative industry power, mold industry get more attention and more energy input, and it has become more important than before. According to the die design of a bending partwith holds, this article introduces the design method of multiple station die, andwewill determine the best choice of die and the manufacturing process of the part after taking three kinds of die(the single station die,multiple station die and compound die) into comparison and analysis the advantages and disadvantages of them. The articlewould like to introduce the die design method from several aspects: the properties ofworkpiece, the forming process ofworkpiece, die parts design, the strength check of die, the manufacturing technology of die and so on.
The difficulty of this design is the arrangement ofworking procedure, and the design principle is to ensure the accuracy and reliability of the die, manufacturing the die under the condition of existing production tooling, reducing the labor intensity, improving the production efficiency. The process of die design includes the mold of the main components designing and manufacturing, stamping equipment selection, punch-gap adjustment and establishment of avital parts machining process. Finishing the design of thewhole die, I must draw a 3D modeling and 2D drawing according the standard specifications.
