Description

шем перемещении под действием собствепного веса спирали, ломаетс , в частности, в выводной проводке 4.The movement of the helix under its own weight breaks, in particular, in the lead wiring 4.

Предлагаемый стан дает возможность заменить резку материала со сложным ирофилем (спирали) сквозной надрезкой непрерывно перемещаемой плоской ленты или полосы, котора  осуществл етс  одновременно с операцией процесса прокатки. Стан обеспечивает повыщение производительности при изготовлении спиралей щнеков и предотвращает искажение их формы при резке.The proposed mill makes it possible to replace cutting of a material with a complicated irofil (helix) with a through cutting of a continuously moving flat tape or strip, which is carried out simultaneously with the operation of the rolling process. The mill provides increased productivity in the manufacture of spirals of the screws and prevents distortion of their shape during cutting.
