Description

так как стенка средней части трубы не утолщаетс  в процессе редуцировани  с нат жением и не нревышает зазора между оправкой и вершиной калибра.since the wall of the middle part of the pipe does not thicken during the process of reduction with tension and does not exceed the gap between the mandrel and the top of the gauge.

.Формула изобретенииFormula of the invention Деформирующий инструмент непрерывного трубопрокатного стана, включающий р д последовательно расположенных валков- с ручь ми, образующими калибры уменьшающегос  диаметра, и расположенную в них с зазором длинную оправкуA deforming tool for a continuous tube mill including a series of consecutive rolls with strands forming gauges of decreasing diameter and a long mandrel disposed in them with a gap уменьшающегос  диаметра, отличающий тем, что, с целью получени  точных труб широкого сортамента с минимальным расходным коэффициентом, группы калибров с оправкой, имеющей диаметр , обеспечивающий уменьшающийс  зазор между оправкой и вершиной калибра, разделены группой калибров, в каждом из которых оправка имеет диаметр, уменьшающийс  соответственно уменьшению диаметра калибра и обеспечивающий сохранение во всей группе равного зазора между оправкой и вершиной калибра.of diminishing diameter, distinguished by the fact that, in order to obtain precise wide-gauge pipes with a minimum expenditure ratio, groups of gauges with a mandrel having a diameter providing a decreasing clearance between the mandrel and the tip of the gauge are separated by a group of calibers corresponding to a decrease in the diameter of the gauge and ensuring that the entire gap remains equal between the mandrel and the tip of the gauge. 4-ь4th ../.V V ч V v../.V V h V v ..
