Hydraulic Press with LS System for Modelling of Plastic Working operation

At first, the paper describes destination of the presented hydraulic press. Next, the substance of load sensing (LS) systems’ operation was introduced, and electro-hydraulic system of this type, installed in laboratory hydraulic press, was described. The control and measurement circuit of the device was also described, and exemplary test results obtained during plastic working operations on soft non-ferrous alloys were presented.
