锻造操作机与夹紧及前提升机构设计
【摘要】 锻造操作机是锻造压力机的重要配套设备，也是汇集机械，液压、电气于一体的重载机械装备之一，掌握大型锻造操作机的核心设计制造技术，对我国经济建设和国防建设具有深远的影响。精密锻造是一个领域，在这个领域里决策可支持系统，它可能是被有效和广泛应用的，还取决于来自锻造磨具设计工程师过去经验的一些知识和规则。对于尝试减少成本和提高可靠性，精确的组成部分变得相当重要，因此在很多应用领域中，本身的规则变成了固有相对于程序的某些部分。在锻造磨具设计中，尺寸精度是主要目标之一。承载能力和任何产品的寿命极大地受尺寸精度影响。为了预测部分精密尺寸和确定对于精密锻造的磨具尺寸，分析影响尺寸精度的因素是很有必要的。磨具和产品的三维演化在每个锻造阶段都应被分析。在这项研究中，由于圆柱形工件的使用，径向和切向应力在磨具应力决定方面常遇到。为了保持锻造的尺寸精度，锻造产品和磨具插入的差异，例如出现弹性磨具扩张和产品收缩。

The design on forging manipulator with clamping and fomer lifting mechanism
【Abstract】 forging manipulator is a important corollary equipment to forging pressure machine.It is also one of the heavy load machinery equipments which compile the machinery :hydraumatic electric into one organic whole.It has a profound effect to national economic construction and the building up of national defence since it commands core design and manufacture technology of heavy forging manipulator. Precision forging is a field in which decision support systems can be effectively and widely applied and depends on knowledge and rules derived from the past experience of forging die design engineers. Precise components are becoming quite important in attempts to reduce cost and improve reliability. There are thus many application areas in which the rules themselves become inherent to the parts or the processes. In forging die design, dimensional accuracy is one of the main goals. The load carrying capacity and life of any forged product is greatly affected by its dimensional accuracy. To predict the precise dimension of the part and determine the die dimension for precision forging, it is necessary to analyze the factors which affect dimensional accuracy. Dimensional evolution of die and product should be analyzed at each stage of forging. In this study, both radial and tangential stresses are encountered in the determination of die stresses since cylindrical workpieces were used. In order to sustain dimensional accuracy of the forging die, differences between the forging product and the die insert such as elastic die expansion and product contraction are presented.
