LOCALLY SHAPING MILL FOR MAKING ARTICLES WITH RELIEF SURFACE FROM SHEET METAL Russian patent published in 2003 - IPC

FIELD: plastic working of metallic sheet materials, possibly manufacture of equipment for locally shaping at making articles of sheet metal. SUBSTANCE: mill includes housing, horizontal motion drive unit, table supporting lower die with preset relief surface and traverse bar having drive unit for vertically moving deforming shaft with elastic envelope. Said table is stationary mounted in housing; traverse bar is joined to horizontal motion drive unit and it is mounted onto paired rollers arranged over and under stationary table. It allows possibility of horizontal motion of traverse bar. In such structure table, lower die and blank are fixed and traverse bar may move horizontally. EFFECT: improved design providing lowered metal consumption, size of mill, its enhanced efficiency. 1 dwg
