发明名称 HYDRAULIC PRESS WITH TWISTED OUT CRANK SHAFT
摘要 construction of presses, namely equipment for making crank shafts of internal combustion engines by volume deformation process. SUBSTANCE: press includes frame, slide, central hydraulic double-action cylinder, beams of upper and lower knocking out members (each beam is driven by means of two hydraulic cylinder) and apparatus for twisting out crank shaft having twisting out unit, twisting out beams and levers. Press includes two closing mechanisms arranged at both sides of central hydraulic cylinder. Each closing mechanism has two levers and double-action closing hydraulic cylinder. Beam of lower knocking out members is provided with mechanism for preventing skewing; the last includes two levers and torsion shaft. Press also includes stops secured to frame with possibility of engaging with ends of beam of upper knocking out members. EFFECT: improved design of press due to elimination of skewing of slide and beams of knocking out members at eccentric loads and due to comfortable arrangement of tank with working liquid and hydraulic drive unit on floor level. 3 cl, 4 dwg
