1、 I 摘摘 要要 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。 本文设计了采用倒装式复合模模具来生产过渡板的设计工艺。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。本文结合过渡板的特点，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

2、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。 本文介绍的模具实例结构简单实用，使用方便可靠，对类似工件的大批量生产 具有一定的参考作用。 关键词关键词: 冲模；复合模；冲裁力；冲裁间隙 II Abstract The stamping dies are widely used in the actual i

3、ndustrial production. Traditional industrial production, the labor intensity of workers in the production of large amount of labor, seriously affecting the efficiency of production. With the development of science and technology, the use of molds in the industrial production has drawn increasing att

4、ention, be applied to industrial production. Automatic feeding of the stamping dies into the actual production of stamping dies can greatly improve labor productivity, reduce workers burden, and has important significance of the technological progress and economic value. Designed flip composite mold

5、 mold design process to produce the transition board. The difficulty of the mold design is how to resolve the punching of holes in the good parts, to determine the mold structure, how to conduct the manufacture of molds and blanking program selected. In this paper, the characteristics of the transit

6、ion board, specifically address the selection and checking of the press, the punch and the die edge size calculations and structural design, positioning design discharge mode design, the main process of the mold parts, standard parts selection, mold assembly of a series of design work, these designs provide practical guidance for similar parts mold design. The salient features of the mold design is to try to use complex composite mold to solve the mold of copy number of the conventional stampin
