Press operator Robert Reece, and press helpers Steven Kinsey and David Boyd, press an 84 inch diameter by 1 inch thick asme eliptical tank head.
After being heated to a temprature of 1850, an 108 inch steel blank is pressed through a draw ring to form a tank head. The blank is brought in using a forklift, and placed in the press set up. After pushing the blank back to the pre-measured stops to ensure a proper lineup, the press is then dropped about 6 to 10 inches. This lowers the hold down. Steel pins are then inserted into the hold down ears to lock the hold down in place. This prevents the steel blanks from wrinkeling or forming knots in the knuckle or straight flange area of the head during pressing. After passing through the draw ring, the head is then blown off using 125 psi of compressed air. When the head is seperated from the plug, the pickup bars are then lowered and the draw ring pot is raised to extract the finished product.
