基于Deform的外轮成形工艺及结构优化

基于Deform软件对某厂生产的汽车外轮成形工艺进行模拟.针对成形过程中出现坯料充不满、锻件上产生折叠、下模冲头容易开裂等现象,分析了成形过程中的金属流动方向和锻造模具所受应力分布,通过减小应力集中、优化锻模倒角、改进锻造过程中金属流向及工艺参数,有效地避免了冲头开裂、锻件折叠和坯料充不满等问题.实践生产表明,对模具的改进和工艺的优化为产品量产提供了理论基础.

Forming Process and Structural Optimization of Outer Hub Based on Deform

Based on Deform software, forming process o{ outer huh in a factory production was simulated. According to phenomenons of filling discontent, folding,lower punch die crack in the forming process,the direction of metal flow, stress distribution of the forging die and stress concentration were studied. Through measurements of reduction of stress concentration, optimization of forging dies chamfering,improvement of metal flow and process parameters in forging, problems of punch crack, folding and filling discontent were effectively avoided. The production practice proves that the improvement on the die and the optimization of the process can provide a theoretical preparation for the mass production.
