[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. They are fireproof partitions with certain fire resistance, located between fire compartments, evacuation stairwells, vertical shafts, etc.

[0003] When installing a fire door, a hinge is needed to hinge the fire door to the door frame, and the hinge needs to be bent and formed during the installation process.

Such traditional bending and forming devices have slow processing efficiency and need to divide the hinge into multiple steps for forming. For this reason, we propose a high-precision bending and forming device for fire door hinges. Utility Model Content
