Efficient stretching forming device for gas cylinder end socket

The utility model relates to the field of end socket machining equipment, in particular to an efficient stretching forming device for a gas cylinder end socket, which comprises an upper die and a lower die, a stretching stamping head is arranged on the upper die, a mounting notch extending to one side of the lower die is formed in the lower die, and a forming die core is rotationally arranged at the position, opposite to the mounting notch, of the lower die. A forming hole is downwards formed in the upper surface of the forming mold core, a mold overturning assembly used for pulling the forming mold core to overturn is arranged on the upper mold, and a reset assembly used for pulling the overturned forming mold core to overturn to achieve reset is arranged on the lower mold. The forming die core is overturned through the die overturning assembly, so that a workpiece which is stretched and punched in the forming hole automatically falls out, manual blanking is not needed, the labor intensity of arms of workers
