FIELD: plastic working of metals, possibly manufacture of bent blanks.
SUBSTANCE: apparatus includes die arranged on table, counter-die mounted in spindle, supporting member used for holding counter-die and mounted in upper slide that may perform sliding motion crosswise relative to blank. Blank is subjected to bending in lower slide mounted with possibility of motion on table in motion direction of upper slide. In order to move counter-die to blank and from it, first double-action cylinder is mounted in lower slide. Second double-action cylinder is mounted with possibility of sliding along upper slide and it is joined with it by means of counter-action rod that may rotate around end of spindle rotating tie rod.
EFFECT: simplified design, enhanced quality of bent blanks.
