Abstract

A methodology for upgrading the hot die's technological forging processes was developed to increase forgings' economic efficiency based on computer modeling in QFORM and DEFORM-3D software packages. Mounting Bracket and Disc hot die forgings, made of aluminum alloys, were selected as the process for the upgrade. Meanwhile, the improved efficiency of technological process must not be connected to replacement of the utilized deforming equipment, considerable renovation of the pressing tool, or any changes in the form and size of the die forgings. Analysis of the existing technologies of the forgings' manufacture provided a basis to define an objective for computer research, namely, reducing the quantity of forging transitions via optimization of the contact friction, temperature, and speed conditions of metal deformation. As a result of forging with the use of new technology developed based on computer modeling, the forgings whose geometry and properties met the normative documentation requirements were produced in one transition in a factory environment. Meanwhile, the prime cost of their manufacture dropping by at least 10%.
