New Type Of Large Tonnage Hydraulic Die Forging Hammer Hydraulic System Structure Design And Research

Forging production with high productivity, high utilization ratio of materialand improve workpiece microstructure and the mechanical properties of thesignificant features of possession, play a decisive role position in the state of theequipment manufacturing industry. As a kind of energy of hammer forgingequipment, forging ability is not affected by the tonnage limit, simple structure,convenient operation, easy manufacture, convenient installation, low price, isstill one of the main equipment of forging production.Our country present hammer most or steam hammer and liquid air hammer,for the study of fully hydraulic die forging hammer of large tonnage is stillrelatively small, with the development of China’s social development andscience and technology, industry, national defense, aerospace and otherequipment manufacturing industry to reduce production costs, reduce productweight, improve product performance and quality of the increasingly highdemand, this also means that the forging production burden will beunprecedented increase, so the design and development of new, large tonnage offorging hammer, hammer, to improve the working performance of forgingquality, production capacity and the degree of automation, has the very vitalsignificance.The400KJ fully hydraulic die forging hammer as an example, studies itsworking principle, structure, function and structure of some parameters werecalculated, and the design of the hydraulic system, the matching, in order tomake the forging hammer hydraulic control system can achieve good controlaccuracy and performance, simulation of hydraulic the dynamic performance ofthe system of the computer is very necessary, two important movement of thehammer, hammer and strike stage mathematical model was established, and theuse of Simulik to create the simulation model of hammer stage and combatphase, hammer blow on the stage and the stage hammer velocity, displacement,acceleration and the hydraulic cylinder cavity, lower oil pressure changing withtime were obtained by means of computer simulation, the hydraulic system, design and development of NC hammer to improve work performance andparameter optimization of hydraulic die forging hammer has provided the theorybasis.
