DRIVE FOR WORKING TOOLS OF FORGING MACHINE Russian patent published in 1994 - IPC

FIELD: metal machining. SUBSTANCE: inner spaces of machine cylinders are connected by pipeline 23, 24 with inner spaces of multiplier containing housing accommodating cylinders 26 with plungers 27. Secured on plungers 27 are rods 28 coming in contact with supports 29 having spherical surface linked to end faces of rods 28 and flat surface interacting with slide 30 made in the form of equilateral wedge. Mounted in hole of slide 30 is connecting rod 31 associated with eccentric shaft 32 supported by bearings of housing. Cylinders 26 accommodate internally diaphragms 33 pressed to plungers 27 by springs 34 and washers 35. When electric motor is switched on, shaft 32 rotates and imparts motion to plungers 27 through connecting rods 31, slides 30, supports 29 and rods 28. Diaphragms 33 in cylinders 26 move and liquid from inner spaces of multiplier is fed into inner spaces of working cylinders of machine. EFFECT: improved efficiency and reliability. 3 dwg
