冷轧带钢夹送矫直装置设计
摘要
随着国民经济的快速发展和生产规模的不断扩大，客户对钢材的质量和精度要求越来越高，大多数钢材必须经过矫直才能满足客户需求。矫直质量已经成为衡量产品竞争力的重要标准。在这种背景下，矫直技术得以迅速发展，应用也越来越广泛。辊式矫直机是目前应用最为广泛的一种矫直机。也是矫直技术发展最为完善的一种矫直机。本文中所设计的矫直机是五辊夹送矫直机组。针对冷轧带钢矫直，进行矫直力，矫直力矩，矫直功率，夹送各装置和零件校核计算。并根据给定的数据进过计算选出所需电机等传动装置。文中所涉及的夹送矫直机在经过一系列设计之后，依据工作原理，还要校核主要零件强度，以保证所设计的机械能够满足实际生产。最后还要结合技术经济环保分析，进行装置评估。
