摘要
随着整车开发越来越多的新工艺、新技术的应用,钢铝混合车身、门盖越来越普遍,伴随而来的是钢铝混合门盖的电泳变形问题越来越成为一个迫切需要攻破的问题。为了解决这个问题,文章通过产品测量数据分析、实物验证、工艺验证等方法系统深入地分析了钢铝混合车门油漆电泳过程中变形问题的产生原因,通过实验验证的方式,从产品数据结构,工艺保证和预变形等方面归纳总结了一套油漆变形解决方案,确保在新项目中成功有效实施相应措施后,降低车门电泳变形量,对新车型投产降本及提升质量水平具有非常重要的指导意义。并提供了一套油漆变形验证的试验方法,用于在其他开闭件的场景进行变形原因分析查找和措施制定,对于类似问题的解决,具有很强的指导、借鉴意义。
As more and more new technologies applied on vehicle, steel-aluminum hybrid BIW(body in white) and closures become more and more common. And the issue of steel-aluminum electrophoresis deformation becomes an urgent and need to be fixed effectively. By measure data analyzation, physic verification, process test, this article systematically analyzed the causes of electrodeposition deformation. By physic experiment, from structure strength improving, process optimization and pre-deformation, this article gives a sort of solution to solve electrodeposition deformation, to reduce deformation and guarantee geometry dimension, reduce manufacture cost,improve product quality. And this article gives an experiment method of door electrodeposition deformation to solve, which can be applied to other closures and back grounds. It’s very useful experience for similar problem to solve.
