PRESS FOR FORMING BY ROLLING AROUND Russian patent published in 2003 - IPC

FIELD: machines for hot or cold die forging of blanks by local deformation process realized in presses for forming by rolling around. SUBSTANCE: press for forming by rolling around includes housing, sphere-moving mechanism, slide and jointly connected one with another, with housing and with slide two prisms for driving slide. Press is provided with additional slide and two pairs of prisms for driving additional slide. Two pairs of driving prisms are arranged at both sides of above mentioned prisms and they are jointly connected one with another, with housing and with additional slide and also with central and two lateral hydraulic cylinders. Rod of central cylinder is jointly connected with one prism of slide drive. Each rod of lateral cylinders is jointly connected with one prism of drive of additional slide. Central cylinder is joined with bracket; lateral cylinders are joined with another bracket. Each bracket is secured to housing with possibility of adjusting their position in plane of prism motion. EFFECT: enlarged manufacturing possibilities, simplified control system, enhanced reliability of press operation. 4 dwg
