[0037] The working principle of the above embodiment is as follows: when the elbow needs to be formed, first, the pipe blank is placed in the mold groove of the lower die 2, and the die block 702 is rotated to the inside of the lower die 2 through the servo motor 705. When the servo motor 705 is started, the worm 704 can be driven to rotate. Through the rotation of the worm 704, the die block 702 can be driven to rotate by the worm gear 703.
