Abstract

PURPOSE:To accumulate and regenerate moving intertia force in an air tank, and make hydraulic devices smaller in capacity, pipelines simpler and equipment cost lower by constituting the three dimensionally operating cylinders of a feed device of hydraulic cylinders and air cylinders operating integrally. CONSTITUTION:An advance cylinder 1 which advances and resets feed bars 2, 2 is constituted of a hydraulic cylinder 1' and an air cylinder 1''. Lift cylinders 3R, 3L which move the bars 2, 2 upward and downward and clamp cylinders 4R, 4L which operate the bars 2, 2 remotely and closely and release a blank material by means of jaws 5 are also constituted respectively of hydraulic cylinders 3R', 3L', 4R', 4L' and air cylinders 3R'', 3L'', 4R'', 4L'', which are operated integrally. The respective cylinders are connected to a low pressure oil supply device 18 by means of pipelines 17 interposed with 2-position type solenoid valves 6-10, hydraulic cam pumps 11-15 and check valves 6. The respective air cylinders are connected to an air tank 30 which absorbs and accumulates cylinder operating gases and holds air pressure at all times by means of pipelines interposed with 2-position type solenoid valves 25-29.
