The maximum energy can be output just by dropping 12.5% of the flywheel speed and the forming speed can be keep stably at 0.5m/s or so. Using the vfd, the deforming speed can be adjustable between 0.25m/s to 0.6m/s, which is suitable for alloy forgings. Using hydraulic clutch control can realize the heavy and light striking and continuous striking, and the striking energy can be loaded at any point of the stroke. High deforming energy, twice compared with other screw presses with the same specification. Using duplex guides of cylindrical guide and the x shape guide, assure eccentric load and suitable for multi-station forging process. Long slider stroke without fixed bottom dead point, it is convenient to adjust dies, which will improve the product efficiency and the die lifetime. Using hydraulic cylinder for return stroke, the flywheel does not need to revolve reversely, so the flywheel energy loss and installed power are small. It is energy-efficient. Striking energy, striking stroke, multi-station forging can be preset by plc. And it can display fault information automatically. It is suitable for continuous product lines for moderate and mass production, and can realize high precision, high efficiency, energy saving and material saving.
1it is an advanced forming process, suitable for high precision forming mufti-shoulder shafts. 2the productivity is twice to five times of traditional die forging. The material usage is high, because of no flash. So the die lifetime is prolonged at least 10 times than used in other traditional machinery. 3t is with high deforming precision, and the material volume distribution is accurate and stable. 4the double eccentric adjusting mechanism for center distance is patent technology. 5t has outstanding advantages, such as high-rigidity, high automation degree and convenient for integrating the whole production line. 6dismantling roller, continuous heating, adjustable revolving speed, center distance adjusting, etc. Are all available. 7friendly working environment can improve the working condition; no shocking and low noise in the operation of rolling, which meet the environmental requirements of modern manufacturing. 8we can provide process, dies designing and manufacturing. And it can be matched with heating furnace to be automatic rolling lines.
