Door and window hinge manufacturing system

The invention discloses a door and window hinge manufacturing system. The door and window hinge manufacturing system comprises a feeding station, a rotating detection station, a stamping station, a pipe bending station for bending a stamped part into a semi-finished bent pipe, a hole forming station for forming holes in the side edges and the ends of the semi-finished bent pipe to obtain hinge holes, an after-treatment mechanism for carrying out after-treatment on the bent pipe with the holes to obtain a finished hinge and a discharging station. The after-treatment mechanism comprises a hingewelding clamp and a welding device. The hinge welding clamp comprises a fixed die and a movable die capable of rising and falling relative to the fixed die. The movable die is located above the fixeddie. The fixed die comprises a lower die seat, and a tool table for clamping the hinge is arranged on the lower die seat. A positioning mechanism is arranged on one side of the tool table. The positioning mechanism comprises p
