摘要
闭式套模在反复冲击、冷热交变、高压摩擦的情况下工作 ,比较容易产生磨损、塑性变形、热裂纹等损坏失效。为了减少模具消耗 ,降低锻造成本 ,针对闭式套模翻修问题 ,提出了模具设计和翻修工艺的技术要点和方法 。
The closed type cover die is working in repeated impact,cold and hot alternation and high pressure friction situation. The die is easy to be crashed,including wearing,plastic deformation,hot cracking etc. In order to decrease damage of the die and to reduce forging cost,The key technique of die design and repair for overhaul closed type cover die is proposed in this paper. In the end,a case of overhaul closed type cover die is given.
