中文摘要: |
凸缘外套在生产过程中产生底部断裂现象,通过三维建模绘制出零件的成形模具,基于Deform 3D软件平台,进行
有限元模拟对比分析,找出产生断裂的因素。通过各个影响因素的对比,对方案1和方案2的可行性进行评估,确定方案2
可行。对凸缘外套的加工工艺进行优化,从而提高凸缘外套生产的合格率,提高坯料的利用率,实现工件的大批量生产。 |
英文摘要: |
Flange sleeve has a phenomenon of fracture on its bottom during the production process. Through drawing
three-dimensional forming mould parts, application of Deform-3D software platform and analysis of finite element
simulation was conducted to find out the factors that could cause the flange sleeve fracture. Through comparison of
different factors. the feasibility of scheme I and scheme 2 were evaluated. and scheme 2 was confirmed. Processing
technology on the flange sleeve was optimized in order to improve the qualified rate. the utilization rate of the billet and
realize the work-piece mass production. |
