Hot Die Forging

The process of manufacturing a part as a semi-finished product (a forging) using hot die forging with further machining can be performed on various types of press forging equipment following several flowsheet variants. The task of selecting the best (most effective) variant is not always obvious. The paper considers the methods of the comparative estimation of the efficiency of several variants of manufacturing a forging of the same part on the basis of the following groups of indicators: metal consumption and forging force.

The process of hot die forging of AK4-1 aluminum alloy billets for the piston of an internal combustion engine (ICE) for an unmanned aerial vehicle (UAV) was simulated using the Deform-3D software package. The object of research was an ICE piston mounted on one of the UAV types of Russian production. Simulation was performed using the following parameters: tooling and billet temperature was 450 °C, ambient temperature was 20 °C, punch speed was 5 mm/s, and Siebel friction index was 0.4. Rigid plastic medium was chosen as a material model. The number of elements (6000) was selected so that at least 3 elements fit in the narrowest section of the part. Thus, as illustrated by the piston die forging, computer simulation in the Deform-3D software makes it possible to develop hot die forging processes for making aluminum alloy billets for UAV ICE pistons. At the same time, computer simulation can be used to evaluate the power parameters of the hot die forging process, study the nature of billet forming in die forging, make necessary adjustments to the virtual process, and develop the design of a die forging tool in order to select the most effective process solutions when designing a real process. The described computer simulation technique can be extended to other aluminum alloy die forgings.

Hot Die Forging

Ti-6Al-4V alloy is used extensively in aerospace industries due to its excellent properties. In this paper, the hot die forging process of the Ti-6Al-4V alloy blade was simulated by using 3D finite element method. Based on the model, the effect of process parameters on the deformation was investigated. The results show that the increase of temperature is beneficial to improving the uniformity of stress distribution. The slower the declining velocity of upper die is, the larger the strain gradient of severe deformation area will be. In addition, the stress distribution gets uniform with velocity decreasing. The large friction coefficient can make strain distribution uneven and cause symmetry of stress distribution. The proposed numerical simulation of hot die forging of blade in the present work may yield important information for the development of hot die forging techniques and the manufacture of blade.
