摘要
为了提高锻件材料利用率,降低锻压成形压力,根据铝轮辋锻件形状特点,优化锻压成形工艺。采用铸造空心圆环坯在芯棒式锻压成形模中进行闭式模锻,将预锻、终锻、切边与冲孔四道工序合为一,无需预锻、切边与冲孔,提高了生产效率与材料利用率;无需大吨位锻压设备,便可保证锻件厚度尺寸。经实践验证,该模具结构简单合理,锻压成形稳定可靠,具有较高的实用价值。
In order to improve material utilization and reduce forging pressure,this paper focuses on forging process optimization for aluminum alloy rims according to its forging shape characteristics.A closed-die forging process was adopted in mandrel forging die with a hollow ring type casting blank,which combined pre-forging,finial-forging,cutting and punching process into a single process.With this technic,the production efficiency and material utilization are improved,and the forge thickness can be ensured without large tonnage forging equipment.Practice proves that this mould structure is simple and reasonable,and the forging process is stable,and so it has a high practical value.
