Anti-seismic support corner brace forming device capable of conducting multiple machining procedures at same time

The anti-seismic support corner brace forming device comprises a workbench, an unwinding machine is installed on the ground on one side of the workbench, strip steel is placed on the unwinding machine, a flatting machine is installed on one side of the upper surface of the workbench, one end of the strip steel can extend into the flatting machine, and the other end of the strip steel can extend into the flatting machine. The flattening machine can flatten strip steel, a positioning mechanism is installed on the working table, and a stamping mechanism is installed on the working table. The device has the beneficial effects that cut-off strip steel can be turned over through the turnover frame, then burrs generated after punching of the strip steel can be upward, the burr faces of corner connectors can be made to face the inner side after the corner connectors are machined, workers can be prevented from being hurt when the corner connectors are installed, the device can automatically conduct continuous feeding
