The invention relates to the technical field of automobile part machining, and discloses a hot stamping forming door ring with a patch plate, which specifically comprises a column A, a roof side rail, a column B, a doorsill and a column H which are connected in sequence, and the junction of the column A and the roof side rail is a first seam; the joint of the A column and the H column is a second seam; the junction of the column B and the roof side rail is a third seam; and the junction of the column B and the doorsill is a fourth seam. An A column patch plate is fixedly arranged on the A column; a B column patch plate is fixedly arranged on the B column; the A column patch plate is flatly laid on the surface of the inner side of the A column; an overlapping part is arranged at the lower end of the A column patch plate; the B column patch plate is flatly laid on the surface of the inner side of the B column. By analyzing the strength requirements of different positions of the door ring, the patch plate is added in a targeted manner, so that the strength requirements of the door ring are met, and the safety performance of an automobile is enhanced. Meanwhile, the material consumption of the patch plate can be reduced, the overall mass of the door ring is effectively reduced, and the requirement for light weight of a vehicle body is met.

    本发明涉及汽车零部件加工技术领域,公开了一种热冲压成型带补丁板门环,具体包括顺次连接的A柱、上边梁、B柱、门槛以及H柱,A柱与所述上边梁的交接处为第一接缝处;A柱与所述H柱的交接处为第二接缝处;B柱与上边梁的交接处为第三接缝处;B柱与门槛的交接处为第四接缝处。A柱上固设有A柱补丁板;所述B柱上固设有B柱补丁板;所述A柱补丁板平铺于所述A柱内侧表面;所述A柱补丁板的下端设有重合部;所述B柱补丁板平铺于所述B柱内侧表面。本申请通过对门环不同位置强度需求的分析,具有针对性的添加补丁板,以满足门环强度需求,加强汽车的安全性能。同时也能减少补丁板的用料,有效降低门环整体质量,达到车身轻量化的要求。
