    摘要: The invention relates to hydraulic control in a hydraulic system for the operation of a machine tool such as a press for processing material of a certain type, especially for the operation of the scrap cutters. Said control allows for impact attenuation and combined rapid motion switching with load compensation and transfer of a hydraulic medium of a hydraulic cylinder for the movement of the other. According to the invention, said control comprises hydraulic media of a hydraulic cylinder for pre-control of a first main valve element (2.4.0), a second main valve element (2.7.0) and a third main valve element (3.7.0) which are functionally combined and a fourth valve (2.5).

    摘要: The invention relates to a press for processing, such as pressing and/or shearing, any type of material (3), particularly scrap metal or metal wastes, comprising: a bed (1) for filling and strand-like compacting and feeding this material (3); a downward-located column (2) having at least one stamper (2.2), which is guided inside the column while being driven by a second hydraulic cylinder (2.2.2) attached to a crosshead (2.1) of the column (2); at least one third hydraulic cylinder (2.4.2), and; a hydraulic control (5) provided with a control block (7) and pipes (6). This press should, in order to increase its overall efficiency, improve the feeding/loading of the material (3) to be processed, ensure a largely coordinated execution of the functional steps, optimize the kinematic sequence of the functional elements and the expenditure of energy therefor, have a reduced loading height and bed length, check the state of wear and monitor the operating state both of the kinematic sequences as well as of the hydraulic system while making them visible to the press operator whereby, all in all, increasing the availability of the press, the intensity of the processing of the material (3) and the output quota thereof from the press.
