Изобретение относитс  к стекольной промышленности и может быть использовано на прокатных машинах, предназначенных дл  формовани  труб из ленты стекла или стеклокристаллического материала.The invention relates to the glass industry and can be used on rolling machines for forming pipes from a tape of glass or a glass-ceramic material.

Известные прокатные валы к машине дл  изготовлени  труб путем моллировани  на одном из них по мере прокатки ленты стекла шириной , равной длине трубы, не могут быть использованы дл  формовани  труб с резьбой на концах.The known rolling shafts to the machine for the manufacture of pipes by bending on one of them as the strip of glass rolled to a width equal to the length of the pipe cannot be used to form pipes with threads at the ends.

Цель изобретени  - получение труб с резьбой на внешней поверхности.The purpose of the invention is to obtain threaded pipes on the outer surface.

Достигаетс  это тем, что формируюш.ий ленту вал выполнен с резьбой на концах и имеет диаметр, равный внешнему диаметру трубы.This is achieved by the fact that the forming tape shaft is threaded at the ends and has a diameter equal to the outer diameter of the pipe.

На фиг. 1 представлены предложенные прокатные валы, поперечный разрез; на фиг. 2- вал с резьбой на концах, продольный разрез; на фиг. 3- полученна  на прокатных валах труба с резьбой на концах; продольный разрез , на фиг. 4 и 5- продольный разрез соответственно вала и полученной при его использовании трубы, имеюи1,ие выступающую над поверхностью резьбу.FIG. 1 shows the proposed rolling shafts, cross section; in fig. 2- shaft with ends at the ends, longitudinal section; in fig. 3- pipe with threaded ends obtained on the rolling shafts; longitudinal section, FIG. 4 and 5 are a longitudinal section, respectively, of the shaft and the pipe obtained by its use, which has a thread protruding above the surface.

Прокатный вал 1, которым формуют верхнюю поверхность ленты 2 стекла, имеет на концах резьбу 3, а диаметр его равен внешнему диаметру трубы 4. По мере того, как из порций расплава 5 стекла прокатывают лентуThe rolling shaft 1, which forms the upper surface of the glass ribbon 2, has a thread 3 at its ends, and its diameter is equal to the outer diameter of the pipe 4. As the batches of glass are rolled out of the melt 5 portions of glass

2 стекла, на последней получают резьбовую нарезку. Одновременно ленту стекла сворачивают на прокатном валу - калибре 6 и сваривают шов, получа  таким образом сварную трубу со сварным швом высокого качества. Поскольку диаметр вала 1 равен внешнему диаметру трубы 4, за один оборот вал 1 прокатывает ленту стекла равную периметру трубы 4. Это позвол ет получить полную резьбу на трубе 4 и при дальнейшем враш,ении вала 1 не нарушить резьбу на ней.2 glasses, on the last receive carving cutting. At the same time, the glass ribbon is rolled up on the rolling shaft - caliber 6 and the weld is welded, thus obtaining a welded pipe with a high-quality weld. Since the diameter of the shaft 1 is equal to the outer diameter of the pipe 4, for one revolution the shaft 1 rolls a ribbon of glass equal to the perimeter of the pipe 4. This allows to get a full thread on the pipe 4 and with further insertion of the shaft 1 does not break the thread on it.

Дл  получени  резьбы, выступаюш,ей над поверхностью трубы 7, примен ют прокатный вал 8.To obtain the thread, protruding above the surface of the pipe 7, a rolling shaft 8 is used.

Преимущество трубы 7 перед трубой 4 состоит в том, что она не ослаблена в месте резьбы.The advantage of pipe 7 over pipe 4 is that it is not weakened at the point of thread.

Предмет и з о б р с т е п и  Subject and content of the article

Прокатные валы к машине дл  изготовлени  труб путем моллировани  па одном из них по мере прокатки ленты стекла шириной, равной длине трубы, отличающиес  тем, что, с целью получени  труб с резьбой на внешней поверхности, формующий ленту вал выполнен с резьбой на концах и имеет диаметр , равный внешнему диаметру трубы.Rolling shafts to a pipe making machine by bending one of them as rolling a glass ribbon with a width equal to the length of the pipe, are different in that in order to obtain pipes with a thread on the outer surface, the tape-forming shaft is threaded at the ends and has a diameter equal to the outer diameter of the pipe.
