TOOL UNIT OF ROLLING STAND OF SHAPE BENDING MILL

摘要

FIELD: rolled stock production, possibly manufacture of merchant bent shapes. SUBSTANCE: tool unit includes housings having struts and chocks and mutually joined by means of cross pieces. Roll journals are mounted in chocks. Vertical rollers are mounted at outlet of rolling stand; said rollers are mounted in slides with possibility of motion in cross guides. At outlet of rolling stand horizontal roller is mounted in struts by means of brackets secured to struts. Said roller is mounted with possibility of vertical motion along predetermined distance and with possibility of rotation around shaping axis by angle 15- 18 degrees in vertical plane parallel relative to roll axes. Ends of shafts of vertical rollers are screwed into slides with possibility of individual vertical motion of each roller. Shafts of rollers are fixed by means of nuts rested upon surfaces of slides. Guides of slides may be spaced by different distance from struts of rolling stand. EFFECT: enhanced quality of bent shapes due to their improved geometry. 1 dwg, 1 ex
