Hot / Warm forging
QForm was originally designed for the simulation of hot and warm closed die forging and it is ideally suited for this process. The software accurately shows material flow in the dies and predicts defects such as voids, laps, and flow-through defects as well as stress and wear in the tools.
QForm can easy simulate almost any kind of forging in virtually any type of equipment and it accurately models the peculiarities of the forging equipment. For example, forging in a mechanical press takes into account the deceleration of the ram as it approaches bottom dead center. It can accurately model standard mechanical presses as well as scotch yoke type presses. For forging on energy related machines such as hammers and screw presses, QForm allows you to vary blow energy just like on your equipment. QForm accounts for the available blow energy allowing you to predict the number of blows required for each impression and it will predict if the blow energy is sufficent to complete the forging. QForm also predicts creep forming for forgings done on hydraulic presses.
You can simulate the temperature, deformation and stress distribution in the workpiece and tool as well as the shape of the grain flow in the forging, which is of utmost importance for quality control. The accurate forging force and energy consumption analysis make it possible to choose the most suitable forming equipment. With such a sophisticated design tool as QFORM, an engineer can optimize the process to avoid defects, reduce the material consumption and enhance the productivity without costly forging trials.Temperature distribution on crankshaft forging
