DEVELOPMENT OF 2400 F FORGING DIE SYSTEM

Abstract

Work aimed toward the reduction of the normally required number of die sequences, necessary to pr duce the selected part, through the use of an extrusion-forging technique and hot dies was completed and is reported. It was demonstrated that the selected forging can be produced directly from hot-rolled bar stock. A number of conditions, however, m st be fulfilled in the forging of this particular configuration: (1) there must be sufficient mass in the preform, (2) the preform must have sufficient length 61/2 to 7 inches, and (3) the preform must be positioned at the back of the die. Three candidate nonmetallic materials TiB2, KT-SiC, and Refr x were subjected to further evaluatiof mild steel were produced which had flow stress approximating that of a refractory alloy at 3000 F, namely 10,000 psi. Castings for hold-down rings, heater blocks, back-up blocks, and water-cooled bottom plates for the 2400 F die system were produced and are ready for machining into prototype dies to study the die heating problems.
