CS263488B1 - Device for welding edges' holding-up during screw tubes welding - Google Patents

Abstract

The solution is to weave production welded tubes. The purpose is to simplify the design forming and welding node at Welding of helical tubes on equipment with tube diameter, adjustable at welding process. Hold device welded edges for helical welding tubes contains dual and inner tubes rollers mounted on the shafts kinematically connected with each other in each pair, wherein each of the rollers is mounted on separate shaft, and made as folded in the direction of the longitudinal axis a; between the parts rollers, while placing one of the rollers they are fastened firmly and stored with them coaxial matching rollers are located radially sliding: saves each of two rollers, • positioned on the opposite side the tubes are equipped with three operas, z no one is made as articulated, and the other two are sprung by coil springs.
