Preforming Optimization of Connecting Rod Die Forgings for X Type Fracturing Pump Based on DEFORM-3D
Aiming at the shape characteristics of connecting rod body forgings for fracturing pumps,a set of forming process scheme was put forward according to the actual production.The influence of preforming shape on forming result was analyzed by finite ele-ment numerical simulation software DEFORM-3D,and three preforming schemes were designed to simulate the final forging pro-cess.By comparing the filling condition,equivalent strain,equivalent stress and metal flow velocity distribution in cross-section during the forming process of different schemes,the reasonable preforming shape and forming process parameters were obtained,the risk of defects was eliminated,and the forming rate of forgings was improved.The results of this study were validated by production trial.
