DEVICE FOR REMOVING INTERNAL FLASH FROM A STRAIGHT-WELD ELECTROWELDED PIPE

摘要

A device for removing the internal flash from a straight-weld electrowelded pipe comprises a casing (4) with groups of cutters (5) provided for removal of the internal flash (d) in steps along the height of the internal flash (d) with simultaneous complete removal of the flash from a given section of the electrowelded pipe; cantilevers (16, 17) connected to the casing (4); cam-shaped support rollers (7, 15) interconnected by synchronizing rods (20, 21) and secured to the cantilevers (16, 17); pressing rollers (11, 28) mounted on the cantilevers (16, 17) and limiting rollers (12, 29) rigidly mounted in the casing (4) and located within the zone of the weld (14); eccentric levers (24, 25) rigidly secured to the cantilevers (16, 17) and interconnected by a rod (27) connected to a mechanism for regulation of the cutting depth of the cutters (5) in the flash (d) to be removed.
