Turnover device for lower die of bending machine

The invention provides a bending machine lower die turnover device, and belongs to the technical field of machining. The structure comprises a lower die body, a supporting frame and a driving device. Wherein the lower die body is rotationally connected with the supporting frame, and the driving end of the driving device is connected with the lower die body so as to drive the lower die body to rotate around a first axis. According to the technical scheme, the number of operators needed when the lower die is overturned can be reduced, manpower is saved, the working efficiency is improved, and safety and stability in the overturning process of the large-tonnage lower die can be guaranteed. 本发明提供一种折弯机下模翻转装置，属于机械加工技术领域。其中，该结构包括：下模本体、支撑架和驱动装置。其中，所述下模本体与所述支撑架转动连接，所述驱动装置的驱动端与所述下模本体连接，以驱动所述下模本体绕第一轴线转。本发明的技术方案能够减少翻转下模时所需要的操作人员数量，节省人力，提高工作效率，并且能够确保大吨位下模翻转过程的安全稳定。
