The invention relates to an automobile front door ring and a manufacturing method thereof. The automobile front door ring comprises a doorsill and a front door opening assembly. The front door opening assembly comprises a column A lower section, a column A upper section, a column B upper section, a column B middle section and a column B lower section, the column A lower section and the column A upper section are connected in a tailor-welding mode, the column A upper section and the column B upper section are connected in a tailor-welding mode, the column B upper section and the column B middle section are connected in a tailor-welding mode, and the column B middle section and the column B lower section are connected in a tailor-welding mode; the A column lower section and the B column lower section are both in lap joint with the doorsill. The problems that the number of parts of the front door ring of a single steel plate stamping and welding structure is large, the manufacturing process is complex, and the precision of the parts is difficult to guarantee can be solved; the problems of high tool equipment requirement, low production efficiency, high manufacturing cost, high manufacturing difficulty and low manufacturing precision of the front door ring of the laser tailor-welded blank integrated stamping structure can be solved.

    本发明涉及一种汽车前门环及其制造方法,汽车前门环包括门槛和前门洞组件;前门洞组件包括A柱下段、A柱上段、B柱上段、B柱中段和B柱下段,A柱下段与A柱上段通过拼焊的方式相连,A柱上段与B柱上段通过拼焊的方式相连,B柱上段与B柱中段通过拼焊的方式相连,B柱中段与B柱下段通过拼焊的方式相连;A柱下段和B柱下段均与门槛搭接。本发明能够防止出现单件钢板冲压焊接结构的前门环所存在的零部件数量多、制造流程复杂、零部件精度难以保障的问题,能够防止出现激光拼焊板一体冲压结构的前门环所存在的工装设备要求高、生产效率低、造价高昂、制造难度大和制造精度低的问题。
