摘要
大型汽车覆盖件模具、精密锻造模具和精密注塑模具等关键高档模具对热处理的精密性、耐磨性、抗氧化性以及冲击韧性等指标提出了更为苛刻的要求,采用先进热处理技术以实现形性精确控制成为必然趋势。与此同时,节能减排和清洁生产是我国建设资源节约型、环境友好型社会的必然选择和实现"碳达峰"目标的必由之路。因此,推广真空热处理、激光淬火、PVD镀膜等先进清洁热处理技术在模具行业的应用成为提高我国模具制造行业技术水平的重要途径。针对模具清洁热处理过程的形性精确控制的现状、问题以及未来发展趋势进行了综述,并提出了推广应用模具清洁热处理技术与装备的具体建议。
Key high-end dies such as large-scale automobile panel dies,precision forging dies and precision injection dies put forward more stringent requirements for idexes such as precision,wear resistance,oxidation resistance and impact toughness of heat treatment and advanced heat treatment technology to achieve the precise control of shape and performance has become an inevitable trend to adopt.At the same time,the energy conservation,emission reduction and clean production are the inevitable choice for our country to build a resource-saving and environment-friendly society and the only way to achieve the goal of‘carbon peak’.Therefore,promoting the application of advanced clean heat treatment technologies such as vacuum heat treatment,laser quenching,and PVD coating in die industry has become an important way to improve the technical level of our country′s die manufacturing industry.Thus,the current situation,problems and future development trends for precise control of shape and performance during die clean heat treatment were summarized,and the specific suggestions for the promotion and application of die clean heat treatment technologies and equipment were put forward.
