WORKING STAND OF TUBE SHAPING MILL Russian patent published in 1995 - IPC

FIELD: metal pressure forming. SUBSTANCE: working stand of tube shaping mill includes a frame in the form of a housing with a cover; rolls, arranged in chocks, mounted in windows of the housing of the frame; a mechanism for axial adjustment of rolls and a unit for radial adjustment of one of the rolls. The rolls are mounted in the housing of the frame in such a way, that a shaping axis is spaced by the same distance from a lower surface of the housing and an upper surface of the cover of the housing, both having identical con ours. The unit for radial adjustment of one of the rolls is in the form a double plunger-wedge apparatus and arranged on a lateral surface of the housing at an operating side of the stand a mechanism for axial motion of the plunger of the above mentioned apparatus. The chocks of second roll are fixed from radial motion with use of two C-shaped brackets, mounted in windows of the housing of the frame and secured to its cover. EFFECT: enlarged manufacturing possibilities of the tube shaping mill, namely shaping of strip material to a tube blank with use of lower arrangement of a lengthwise seam relative to an axis of shaping process. 1 cl, 2 dwg
