一、锻模硬度与寿命的关系锤上锻模合适的热处理硬度应该保证它在热工作状态下具有最佳的综合机械性能——足够的强度、耐磨性和冲击韧性,这是防止锻模过早失效的重要条件。锻模失效的机理是复杂的,造成锻模失效的因素是多样的,但是,任何一种失效形式,无不与锻模的热处理硬度有着密切的联系。硬度过高,材料的冲击韧性降低,容易造成锻模的脆性破裂,然而,过多地降低硬度,模膛则易于磨损或压塌;为了防止疲劳 First, the relationship between the hardness and life of the hammer Hammer on the appropriate heat treatment forging hardness should ensure that it has the best overall mechanical properties in the hot working conditions - sufficient strength, wear resistance and impact toughness, which is to prevent forging die Premature failure of the important conditions. Forging die failure mechanism is complex, resulting in forging die failure factors are diverse, however, any failure form, are all with the heat treatment forging die hardness is closely linked. Hardness is too high, the impact of the material to reduce the toughness, likely to cause brittle rupture of the die, however, too much to reduce the hardness, the mold is easy to wear or crushed; in order to prevent fatigue
