A blank positioning and guide construction which includes guide pin slotting that effects the accurate positioning of the sheet on the forming die and guide pin thereof and which provides for the enlargement of the guide pin slot by the predetermined deformation of portion of the sheet at a predetermined bend line adjacent to the guide pin slot to eliminate adherence of the part to the pin so that the part can be ejected from the die without detrimental part distortion of the part.

Guide pin slot arrangement for super plastic forming blanks providing improved blank guidance and formed part release

Equipment and method for the rapid and easy extraction of formed metal parts from forming dies while in a press and operating at elevated temperatures. The invention features the controlled supply of streams of air or other inert gas to the interface of the hot surface of the forming die and the formed panel to augment removal so that flaws from removal equipment are minimized for optimized production of high quality parts. High velocity air is discharged through nozzles onto the forming surfaces of hot forming dies to cool the forming die and the part that contract at different rates and pop the part from the surface.
