光企9007铝型材挤压模具强度与刚度校核

Strength and Rigidness Check for the Extrusion Die of Guangqi 9007 Aluminum Alloy Profile

采用材料力学模型，对自行设计的光企9007铝合金型材挤压模具进行了理论强度与刚度校核。计算结果表明，上模分流桥、下模悬臂等危险部位均满足强度要求，下模悬臂的刚度也同样满足使用要求，证明该模具的设计合理可行。

Theoretical strength and rigidness check for a self--designed extrusion die of aluminum alloy profile Guangqi 9007 has been conducted using material mechanics in this paper. The calculated results show that, the dangerous structures such as the divergent bridges of the upper die and the cantilever of the lower die can satisfy strength requirement, and the cantilever structure is rigid enough for service. Strength and rigidness check proves that the extrusion die design is reasonable and feasible.
