The invention relates to a production technology of high-strength automobile door and window sashes. The production technology comprises the following steps of S1, printing automobile door and window sash frames; S2, performing automobile door assembling; S3, performing electrophoretic coating; S4, performing drying; S5, performing buffer layer filling, wherein the gaps between automobile door inner plates and automobile door outer plates are filled with a foaming agent; S6, performing spraying, wherein the surfaces of the automobile door inner plates and the automobile door outer plates are sprayed with a layer of high-strength paint, and natural airing is conducted for 4-6 h; and S7, installing sealing strips. According to the production technology, a blank is injected into a 3D printer, the automobile door and window sash frames are printed through the 3D printer, and then the automobile door and window sash frames are combined with automobile door frames to form the automobile door and window sashes in different shapes. The production process is simple, meanwhile, the working efficiency is greatly improved, the 3D-printed automobile door and window sash frames are integrally formed, no welding point exists, the structural strength of the automobile door and window sashes is improved to a large extent, and the safety is improved.
本发明涉及一种高强度汽车车门窗框生产工艺,包括以下步骤:S1,打印车门窗框框架;S2,车门组装;S3,电泳涂装;S4,烘干;S5,填充缓冲层:在车门内板与车门外板之间填充发泡剂;S6,喷涂:在车门内板与车门外板的表面喷涂一层高强度涂料,自然晾干4‑6h;S7,安装密封条。本发明通过将坯料注入3D打印机,利用3D打印机打印出车门窗框框架,在通过与车门框架进行组合形成不同形状的汽车车门窗框。不仅生产工序简单,同时大大提高了工作效率,并且3D打印出的车门窗框框架为一体成型,没有焊接点,很大程度上提高了汽车车门窗框结构强度,提升了安全性。
