FIELD: metal working. SUBSTANCE: proposed mechanical press contains slide installed in bed guides and coupled with crankshaft by articulated two-link mechanism. Electric motor installed on bed is connected with flywheel rigidly installed on crankshaft by flexible drive. Clutchless electromagnetic press control mechanism includes at least one electromagnet. Armature of electromagnet of clutchless control mechanism is made in form of bellcranks installed for turning on axle. Outer arm of bellcrank interacts with flat of fixed core of electromagnetic coil through fitted-on movable spring-loaded adjustable core with flat. Inner arm of bellcrank is coupled through axle with outer end of transfer mechanism rocker. Slide upper working position stop is made, for instance, of rubber in form of elastic ring with through central hole. Thickness of elastic ring exceeds size of end of rod projecting from piston. EFFECT: improved reliability, increased service life and capacity of press. 2 cl, 34 dwg
