Mechanical press hydraulic overload protector is composed of oil pressure pump using compressed air as pow-er source,high precise oil pressure overload unloading valve and inching switch. Operating states include working or-der,overload state and press falling down state. Based on analysing these three kinds of state,design formulas were deduced,including setting slide block preeompressions,the unloading pressure and the maximum load of unloading valve. Finally,some application examples were particularized to verify these,and some suggestions were gave for it.
