Abstract

Технологический инструмент прошивного стана, включающий биконические валки, с пережимом между конусами, установленную между ними прошивную оправку, носок которой выдвинут за пережим в сторону входа в очаг деформации, направляющие линейки, имеющие входной конический и выходной участки с гребнем между ними, который расположен в пережиме валков или сдвинут в сторону носка оправки, отличающийся тем, что выходной участок линеек выполнен с криволинейной вогнутостью в сторону прошиваемых заготовок.A technological tool for a piercing mill, including biconical rolls, with a pinch between the cones, a piercing mandrel installed between them, the nose of which is extended beyond the pinch towards the entrance to the deformation zone, guides with an input conical and output sections with a crest between them, which is located in the pinch rolls or shifted to the side of the toe of the mandrel, characterized in that the output section of the rulers is made with curvilinear concavity towards the stitched blanks.
