die forging hammer is suitable for forging these forged connecting rods, its blow energy can reach 18.9kj.Blow energy in forging hammer forging is very important,because it can keep the metal flow during forging hammer blow deformation.The biggest force depends on the actual deformation.For small deformation,very large force will destroy mould and equipment.With the increase of deformation,the impact power cuts.The application of programmable forging hammer can minimize wear and tear of equipments,and improve energy utilization.
