Description
Известные способы накатки кольцевого гофра роликами и способы штамповки резиной недостаточно производительны и не дают возможности получать шланги неограниченной длины.Known methods of knurling ring corrugation rollers and methods of rubber stamping are not sufficiently productive and do not allow to get hoses of unlimited length.
Предложено накатку осуществл ть шнеками с переменным шагом, что позвол ет получать шланги неограниченной длины.A knurling was proposed to be performed with variable pitch augers, which makes it possible to obtain hoses of unlimited length.
Сущность предлагаемого способа заключаетс в том, что шнеки с переменным шагом, расположенные по окружности трубы, синхронно враща сь вместе с трубой, движущейс поступательно, производ т накатку трубы с кольцевым гофром, причем накатка ведетс без оправки.The essence of the proposed method lies in the fact that screws with variable pitch, located around the circumference of the pipe, simultaneously rotate together with the pipe moving progressively, knurling the pipe with an annular corrugation, and the knurling is carried out without a mandrel.
Сближение гофров сформованной гофрированной трубы на выходе достигаетс с помощью шнеков с переменным уменьшающимс шагом.The convergence of the corrugations of the formed corrugated pipe at the outlet is achieved with the help of augers with variable decreasing pitch.
Предмет изобретени Subject invention
Способ изготовлени гибких металлических трубопроводов (шлангов) путем накатки шнеками , отличающийс тем, что, с целью получени шлангов с кольцевыми гофрами неограниченной длины, накатку трубы производ т без оправки шнеками с переменным шагом, которые вращаютс вокруг трубы, движущейс поступательно.A method of manufacturing flexible metal pipelines (hoses) by rolling screws, characterized in that, in order to obtain hoses with ring corrugations of unlimited length, the rolling of the pipe is carried out without a mandrel with variable pitch screws that rotate around the pipe moving progressively.
