FIELD: machine engineering, namely press equipment designed for bending sheet metal, possibly manufacture of auger blades. ^ SUBSTANCE: press includes housing, hydraulic cylinder kinematically coupled with one of units for fastening blank. Housing is in the form of closed power circuit inside which hydraulic cylinder is arranged. One end of hydraulic cylinder is joined with power circuit; its other end is joined with central shaft. Said central shaft is mounted inside stationary unit for fastening blank with possibility of lengthwise motion along it and it is fixed against rotation relative to it. Stationary unit for fastening blank is mounted in power circuit at side opposite relative to hydraulic cylinder and it is in the form of sleeve with -shaped cutout. Movable unit for fastening blank is in the form of sleeve secured to central shaft at side opposite relative to hydraulic cylinder. Units for fastening blank in zone of -shaped cutouts are provided with -shaped clamps for placing in them blank of auger blade. ^ EFFECT: operational reliability, lowered size and mass of press. ^ 6 dwg, 1 ex |
