摘要
随着汽车行业的飞速发展，人们对于能源的消耗和污染排放与全球环境保护之间的矛盾日益突出，而汽车轻量化是解决这一矛盾的主要出路之一。目前，通过热冲压成形技术将高强度钢、铝合金等轻量化材料制造成高强车身构件是实现汽车轻量化的有效途径。但是，传统热冲压加热技术所需的加热时间长、成形件质量不佳、生产效率低下，使得寻求一种节能环保并且更高效的加热设备成为了热成形技术发展的重要方向。导电加热是一种节能的、更高效的加热方式，它能够有效地降低加热时间，提高加热效率，减少坯料表面氧化等优势，因此开展导电加热装置系统开发具有重要的研究意义和应用价值。本文以B柱加强板的冲压成形为实例，进行了热冲压快速加热系统总体设计及优化。研究结果对热冲压快速加热系统的发展具有一定的指导意义。主要进行的工作如下：
（1）研究相关的热成形工艺发展现状，针对热成形加热系统设计有初步的构思，选择铝合金7075-T6作为成形材料，以导电加热为主要加热方式；
（2）完成导电加热系统总体设计，并进行相关的加热装置参数的理论计算； [资料来源：Doc163.com]

Abstract
With the rapid development of the automobile industry, the contradiction between the exploitation and use of energy and the sustainable development of the world has become increasingly prominent, and the light weighting of automobiles is one of the major solutions to this contradiction. At present, the manufacture of high-strength body components from light-weight materials such as high-strength steels and aluminum alloys through hot stamping is an effective way to achieve lighter weight. However, the traditional hot stamping heating technology requires long heating time, poor quality of the formed parts, and low production efficiency, making it an important direction for the development of the hot forming technology to seek an energy-saving and environmentally-friendly and more efficient heating equipment. Conductive heating is an energy-saving and more efficient heating method. It can effectively reduce the heating time, improve the heating efficiency, reduce the surface oxidation of the billet and other advantages, so the development of conductive heating device system has important research significance and application value.In this paper, the stamping forming of B-pillar reinforcing plate is taken as an example, and the overall design and optimization of hot stamping rapid heating system are carried out.The research results have certain guiding significance for the development of hot stamping rapid heating system. The main tasks are as follows:
