冲压模具设计
摘 要
冲压模具在实际工业生产中应用广泛。在传统的工业生产中，工人生产的劳动强度大、劳动量大，严重影响生产效率的提高。随着当今科技的发展，工业生产中模具的使用已经越来越引起人们的重视，而被大量应用到工业生产中来。冲压模具的自动送料技术也投入到实际的生产中，冲压模具可以大大的提高劳动生产效率，减轻工人负担，具有重要的技术进步意义和经济价值。
本文提出采用模具来生产止动件新工艺，并针对某规格夹具止动件设计了复合模。该模具设计的难点主要是如何解决好零件中的孔冲裁、确定模具结构、如何进行模具的制造及冲裁方案选定等。本文结合止动件的特点，具体解决了压力机的选择与校核、凸模和凹模刃口尺寸计算及结构设计、定位方案设计、卸料方式的设计、主要模具零件的加工工艺、标准零件的选用、模具的装配等一系列的设计工作，这些设计可为类似的零件模具设计提供现实的指导意义。此次模具设计的突出特点是尝试使用复杂的复合模具，解决常规冲压工艺模具套数多、工艺路线长、生产成本高、效率低等缺点，并为以后此类零件冲压工艺的编制及模具设计提供了可靠的依据。

Abstract
Punching die has been widely used in industrial production. In the traditional industrial production, the worker work very hard, and there are too much work, so the efficiency is low. With the development of the science and technology nowadays, the use of punching die in the industial production gain more attention, and be used in the industrial production more and more. Self-acting feed technology of punching die is also used in production, punching die could increase the efficience of production and could alleviate the work burden，so it has significant meaning in technologic progress and economic value.
This Article proposes using mold to produce to stop moving pieces of cold stamping of the new technology, And against a standard fixture retainer design of the compound dies. The main problems of this mold design is how to solve 3mold and selected blanking programs and so on. This Article Combine the characteristics of retainer, concretely solve the choice and verify check of the press machine, the numeration and structure design of the point dimension of punch and matrix, the locating project design, the method of stripper, the main mold parts processing, the choice of standard parts, the design of the model assemble. These designs can provide realistic guiding significance for similar mold design. But the characteristics of the design is to try to using the complicate dies. To solve the problem of original process, such as large numbers of die, long process of technology, high production cost, low efficiency, difficulty in keeping symmetry of working parts are solved, and a reliable evidence for the workout of stamping process and die design of these parts is provided.
key words：dies; compound dies; technology analyse；blanking force; blanking dearance.
