Description

Изобретение касаеюь o6pauosщ мвгаллов давлением и может быть использовано при изгошовдании профи дированных fpjd типа ппавникоВЫХоThe invention is based on pressure and can be used for executing a projected fpjd of the type of ppavniki

Известен способ прокагки с продольными реб рами кипа плавниковых включающий деформацию предварительно спрофи ированной заготовки в профильных калибрах Однако при прокатке плавниковых труб из круглой заготовки на их внутренней поверхности под плавниками образуетс  ут ука из-за большой неравномерности деформации трубы по сечению, что отрицательно сказываетс  на качестве прокатываемых труб и производительности оборудовани .There is a known method of forging with longitudinal ribs of a fin bale involving the deformation of a pre-spliced billet in profile calibers. rolled tubes and equipment performance.

Описываемый способ отличаетс  тем, что в качестве предварительно спрофилированной заготовки используют заготовку с цилиндричесJKMM внутренним отверстием и овальной наружной повэрхност ью.The described method is characterized in that, as a pre-profiled blank, a blank with a cylindrical inner bore and an oval outer surface is used.

На чертеге показаны три положени  калибров стана ХИТ, на котором прокатывают трубы подобного типаThe drawing shows three positions of the calibers of the HIT mill, on which pipes of this type are rolled.

а) в крайнем заднем положении клетиa) in the rearmost position of the cage

о) в промежуточном положевиа клети|o) in the intermediate stand |

в) в крайнем переднем положении клети.c) in the extreme forward position of the cage.

Применение предлагаемого спо5 соба обеспечивает значительно меньше , чем при прокатке готовых паавниковых труб из круглой заготовки, неравномерность деформации по сечению трубы благодар  тому, что The application of the proposed method ensures significantly less than when rolling ready-made paavnik tubes from a round billet, the non-uniformity of deformation over the cross section of the pipe due to the fact that

0 круглую часть плавниковой трубы прокатывают из участков заготовки с -меньшей толщиной стенки, а формовку плавников осуществл ют из участков с большей толщиной .стенкиг устран   тем самым причи1ну образовани  ут жки под плавни0, the round part of the fin tube is rolled from the sections of the billet with a smaller wall thickness, and the fin is formed from sections with a greater thickness of the wall, thereby eliminating the formation of a smoothing tail.
