Description
В Прокатном стане вместо предохранительных стаканов под верхним валком устанавливаютс гидравлические цилиндры 1, (см. чертеж), св занные с аккумул тором 3 посредством трубы 2 с краном, которым регулируетс поток жидкости в трубе.In the rolling mill, instead of safety glasses under the upper roll, hydraulic cylinders 1 are installed (see drawing) connected to the accumulator 3 by means of pipe 2 with a valve, which regulates the flow of fluid in the pipe.
В зависимости от величины открыти крана скорость вытекани жидкости из гидравлических цилиндров под действием силы давлени металла на валок будет различной.Depending on the size of the opening of the crane, the rate at which the liquid flows out of the hydraulic cylinders under the action of the force of the metal on the roll will vary.
В момент задачи полосы в валки при минимальном зазоре между валками передний конец обжимаетс максимально. Давление металла на валок передаетс гидравлическим цилиндром и заставл ет подниматьс их корпуса (вместе с подушкой) за счет жидкости, перетекающей в аккумул тор. При этом поршень 4 гидравлического цилиндра, расположенный между станиной стана и корпусом цилиндра, фиксируетс нажимным болтом 5.At the time of the task of the strip into rolls with a minimum gap between the rollers, the front end is crimped to the maximum. The pressure of the metal on the roll is transmitted by the hydraulic cylinder and causes their bodies to rise (together with the pad) due to the fluid flowing into the accumulator. In this case, the piston 4 of the hydraulic cylinder, located between the bed of the mill and the cylinder body, is fixed by a pressure bolt 5.
В результате подъема валка зазор между валками увеличиваетс , что увеличивает и сечение полосы.As a result of a roll lift, the gap between the rolls increases, which also increases the cross section of the strip.
Предмет изобретени Subject invention
Стан дл прокатки профилей переменного сечени с изменением рассто ни между валками в процессе прокатки, отличающийс применением гидравлических цилиндров, вытесн ющих жидкость в аккумул тор , с целью увеличени рассто ни между валками.A mill for rolling variable cross section profiles with a change in the distance between the rollers during the rolling process, characterized by the use of hydraulic cylinders displacing liquid into the accumulator in order to increase the distance between the rollers.
