Abstract

An analytical model of the cold wire drawing process is used to implement an optimization procedure. The optimization aims to minimize the number of passes required to achieve a given reduction while maintaining a safe value of the drawing stress in each step. The number of passes and the sequence of intermediate diameters are the output of the optimization model. The sequence of diameters is optimal in the sense that minimizes a mathematical objective function, and their values must be considered a first attempt to determine appropriate values for a specific wire drawing operation. With respect to prior contributions, the work hardening of the material is exploited to reduce the number of passes. The reduction of the number of passes yields lower values of the aspect ratio, defined as the mean diameter divided by the contact length, which is an important factor to prevent the onset of internal defects. The optimization is performed numerically with mathematical programming and metaheuristic algorithms.
冷拉丝工艺的数学优化
利用冷拔过程的解析模型,实现了冷拔过程的优化。优化的目的是最大限度地减少所需的通过次数,以实现给定的减少,同时保持每一步的拉伸应力的安全值。优化模型的输出为道次数和中间直径的顺序。在最小化数学目标函数的意义上,直径序列是最优的,它们的值必须被视为确定特定拉丝操作的适当值的第一次尝试。相对于先前的贡献,材料的加工硬化被用来减少孔道数。通过次数的减少产生较低的宽高比值,定义为平均直径除以接触长度,这是防止内部缺陷发生的重要因素。采用数学规划和元启发式算法进行数值优化。
