Abstract
EHL system does not need conventional hydraulic equipment. This is possible to save space and energy.EHL press machine is consisted of five components, such as master cylinder, slave cylinder, servomotor, ball screw, etc. Master cylinder and slave cylinder are coupled by fluid line. Master cylinder reciprocalmotion is made possible by suitable choice of area ratio of both cylinders. Slave cylinder is driven bymaster cylinder and the former force is amplified by the area ratio of the former and the latter. Accumulator is used for compensation of fluid expansion due to temperature change. Semi-closedcontrol of EHL press machine is simple but positioning accuracy is not sufficient due to compression offl uid. Therefore full closed control is required for good position accuracy. We tried application of thissystem to the clamping device of 10-ton load. By this combination, tact time becomes as small as 3second.
