一、概述在金属塑性成形领域中,锻模生产正日趋发展,与其密切相关的模具寿命问题已成为大家关注的一个重要问题。众所周知,锻模的工作条件十分恶劣,它直接承受高温、高冲击和复杂交变应力的作用。目前国内锻模的寿命不够理想,而锻模的寿命恰恰直接影响产品成本和生产周期。所以,努力提高锻模的使用寿命是具有很大现实意义的。 (一) 热锻模的工作条件及破坏 First, an overview In the field of metal plastic forming, forging die production is increasingly developed, and its closely related to the issue of die life has become an issue of concern to everyone. As we all know, the working conditions forging die is very poor, it directly withstand the effects of high temperature, high impact and complex alternating stress. At present, the life expectancy of the forging die in the country is not ideal, but the die life just has a direct impact on product cost and production cycle. Therefore, efforts to improve the service life of the die is of great practical significance. (A) hot forging mold working conditions and damage
