(54) МНСйГОВАЛКСеЫЙ КАЛИБР(54) MNSEYGOVALKSY CALIBER
Изобретение относитс к прокатному и волочильному производству и может быть использовано на станах с многовалковыми калибрами. По основному авт. св. Ms 725727 ювестен многовалковый калибр, включающий несколько валков, собранных со стыковкой их бочек относительно боковых граней соседних валков, прн этом на каждом валке выполнено по два ручь , валки собраны с возможностью регулнровани раз меров калибра посредством осевого н радиальногч) перемещени валков, а калибр ,как хфавило, включает три или четьтре валка Cl . Однако, если известный многовалковь1й калибр образован трем валками, то в месте контакта бочек с острыми ребрами боковых граней соседних валков происходит быстрый износ поверхностей ручьев. При этом, если калибры подвергнуть пред| варительному напр жению, острые ребра боковых граней валков скалываютс , Ч;то снижает стойкость валков. Цель изобретени - повышение стойкости валков путем снижени износа бочек и устранени скола ребер боковых граней валков у трехвалкового калибра. Поставленна цель достигаетс тем, что в известном многовалковом калибре ручьи расположены на различных по диаметру участках бочки и каждый валок вьшолнен с двум коническими участками стыковки с соседними валками, один из которых расположен между речь ми, а другой - на конце бочки со стороны . ручь большего диаметра. Так как стыковка соседних валков осуществл етс по коническим участкам, а не по ребрам , то значительно снижаетс износ бочек валков у орехвалкового калибра и устран етс скол ребер боковых граней, что повьшает стойкость валков. Расположение ручьев на различных по диаметру участках бочки позвол ет разместить на бочке два ручь и состыковать соседние валкв коническими участкаThe invention relates to rolling and drawing production and can be used on mills with multi-roll gauges. According to the main author. St. Ms 725727 is a multi-roll caliber that includes several rolls assembled with their barrels docked relative to the side edges of the adjacent rolls, two rolls are made on each roll, rolls are assembled with the possibility of adjusting the size of the gauge by axial and radially moving the rolls, and caliber, as hfavilo, includes three or four rolls of Cl. However, if a well-known multi-shaft caliber is formed by three rollers, then at the point of contact of the barrels with the sharp edges of the side faces of the neighboring rolls, the surfaces of the streams are quickly worn. In this case, if the calibers are subjected to pre | pressure, the sharp edges of the side edges of the rolls are clipped, h, which reduces the resistance of the rolls. The purpose of the invention is to increase the durability of the rolls by reducing the wear of the drums and eliminating the chipped ribs of the side faces of the rolls at the three-roll caliber. The goal is achieved by the fact that in a well-known multi-roll caliber the streams are located at different sections of the barrel and each roll is made with two conical sections of the dock with adjacent rolls, one of which is located between the mouths and the other at the end of the barrel from the side. brook of larger diameter. Since the adjacent rolls are joined along conic sections, and not along the edges, wear of the roll barrels near the walnut caliber is significantly reduced and chipping of the edges of the side faces is eliminated, which increases the resistance of the rolls. The arrangement of the streams at different sections of the barrel allows placing two streams on the barrel and joining the adjacent Valkws with conical sections.
