Integrally-formed lightweight process for automobile door frame

The invention discloses an automobile door frame integral forming lightweight process, which belongs to the technical field of automobile door frame manufacturing, and comprises the following steps: 1, preparing a door frame forming plate; secondly, the door frame forming plate is cut into appropriate sizes through laser cutting equipment, and all parts of the door frame are obtained; thirdly, tailor-welding all parts of the door frame through tailor-welding laser equipment; and fourthly, all parts of the door frame are subjected to integrated high-pressure die-casting forming through high-pressure die-casting forming equipment. In this way, the problems of breakage and the like caused by reduction of the overall strength of the automobile door frame assembly due to poor welding quality can be avoided, and the safety performance of the automobile door frame assembly can be improved; the lightweight design of the automobile door frame can be further improved, the weight of an automobile can be reduced, and the
