Description

(54) СПОСОБ ИЗГОТОВЛЕНИЯ МНОГОГРАННЫХ ТРУБ(54) METHOD FOR MANUFACTURING MULTIPLE PIPES

Claims (1)

Формула изобретенияClaim Способ изготовления многогранных труб дреимущественно волочением, включающий деформацию круглой заготовки в роликовых калибрах с прямолинейными сторонами, отличающийся тем, что, с целью уменьшения радиусов сопряжений граней, трубу на предчистовом проходе деформируют в калибрах, имеющих форму выпуклого многоугольника, периферийные зоны выпуклых граней которого, примыкающие к углам, выполняют в виде прямолинейных участков, параллельных граням готового профиля и имеющих длину 0,5—1,0 толщины стенки заготовки.A method of manufacturing multi-faceted pipes is mainly drawn, including the deformation of a round billet in roller gauges with straight sides, characterized in that, in order to reduce the radius of the edge mates, the tube on the pre-passage passage is deformed in gauges having the shape of a convex polygon whose peripheral zones of convex faces adjoining to the corners, performed in the form of straight sections, parallel to the edges of the finished profile and having a length of 0.5-1.0 wall thickness of the workpiece.
