Article Preview

With the rapid development of modern industry, more and more high requirements for forging velocity and control precision have been proposed. Because it can not only increase productivity, but also can reduce the loss of the workpiece and save raw materials. Due to some characteristics such as high pressure, large flow, heavy moving inertia and so on, the process control performance of the fast forging hydraulic presses often have difficulty in their coordination between rapidity and stability, large shock during pressure relief and flow relief, low control accuracy and high accident rate. To overcome the negative influence and improve forging press performance, it is important to design forging curve. 22MN fast forging hydraulic press adopts electro-hydraulic proportional control system, the simulation and test results approved that the fast forging hydraulic press has high control accuracy and works stably without shock.
