冲压加工在电子管另件制造中占很大的比例。为了提高模具的性能与寿命以及满足冷挤压、精密冲裁等冷变形新工艺推广的需要,正确选用模具材料与尽量采用先进的热处理工艺,将是两个很重要的问题。在这两个方面我国不少单位已作了大量的工作,并取得了可喜的成果。下面仅我们所了解的内容,将冷模具钢性能与热处理特点作些综合介绍。由于实践经验的缺乏与理论上的困难,很可能有谬误之处,希望大家批评指正。
Stamping parts in the manufacture of other parts of tubes account for a large proportion. In order to improve the performance and life of the mold as well as meet the needs of cold extrusion, precision blanking and other cold deformation of the promotion of new technology, the correct choice of mold materials and try to use advanced heat treatment process will be two very important issues. In both these aspects, many units in our country have done a great deal of work and have achieved gratifying results. The following is only what we know, the cold die steel performance and heat treatment characteristics for some comprehensive introduction. Due to the lack of practical experience and theoretical difficulties, there may be fallacies, I hope everyone criticism.
