摘要
对于无飞边闭式模锻 ,由于各种因素的影响 ,很难使坯料体积与闭式模膛的容积恰好相等。若严格满足闭式模锻对原毛坯体积的要求 ,必然导致下料难度的增加 ,甚至不能实现 ,解决这一难题的有效途径是在模具上设置工艺补偿空间 ,即多余金属分流腔。阐明了设置分流腔的机理 ,分流腔的设置原则以及分流腔的结构型式 。
It′s very difficult to make the volume of blank material and bulk of closed cavity equal because of all kinds of influence of factors for no-draft closed-forging. If the requirement of closed-forging to blank volume must be satisfactory,it will lead to the difficulty of blank, even it can′t be realized. The effective methed to solve this problem is to set up technological compensation space in die-draft splitter cavity.
