随着近几年我国汽车工业的飞速发展,与之相应的汽车零部件尤其是精密锻件的加工技术、制造水平也在不断提高。为适应精密热模锻件技术的发展,有必要对以往的标准进行相应的补充与修正。现参考国外同行业的技术标准,结合国内现有钢质精密热模锻件的制造水平、技术能力和生产现状,从原材料控制、制坯、锻造、热处理、检验等各个过程,对钢质精密热模锻件的加工制造制订技术指导规范。
With the rapid development of China’s automobile industry in recent years, the corresponding auto parts, especially precision forging processing technology, the manufacturing level is also rising. In order to adapt to the development of precision hot die forging technology, it is necessary to supplement and amend the previous standards accordingly. Now with reference to the technical standards of foreign counterparts, combined with the manufacturing level, technical capabilities and production status of the existing domestic steel precision hot forging, from the control of raw materials, blank, forging, heat treatment, testing and other processes, the precision steel heat Forging pieces of the manufacturing process to develop technical guidance.
