Abstract
Изобретение относитс к обработке металлов давлением и может быть использовано в прокатном производстве дл разделени проката, получаемого при многоручьевой прокатке. Цель изобретени - повышение производительности и сокращение производственных площадей за счет совмещени продольного разделени и кантовки проката. При заходе в устройство раската, состо щего из трех овалов, соединенных перемычками, металл захватываетс вращающимис дисковыми ножами 2 и 3. В результате этого ножи 2 и 3 перерезают режущими кромками 4 перемычки между овалами. Одновременно вследствие контакта овалов с поверхност ми 5 и 7 ножей и дополнительных дисков 6 происходит поворот поперечных сечений овалов раската. 2 ил.The invention relates to the processing of metals by pressure and can be used in the rolling industry for separating the rolled products obtained by multi-strand rolling. The purpose of the invention is to increase productivity and reduce production space by combining longitudinal separation and rolling of the rolled products. When entering a rollout device consisting of three ovals connected by bridges, the metal is caught by the rotating disk knives 2 and 3. As a result of this, the knives 2 and 3 cut the bridges between the ovals with the cutting edges 4. At the same time, due to the contact of the ovals with the surfaces 5 and 7 of the knives and additional discs 6, the cross sections of the roll ovals rotate. 2 Il.

Jda ф^,,· 1, ^бражена схема устройства для продольного разделения движущегося •проката в рабочем положении; на фиг. 2 — профиль разделяемого проката, полученного многоручьевой прокаткой.Jda ф ^ ,, · 1, ^ a diagram of a device for the longitudinal separation of moving • rolled products in working position is shown; in FIG. 2 is a profile of the rolled stock obtained by multi-strand rolling.
Устройство для продольного разделения движущегося проката содержит установленные на верхнем и нижнем валах 1 верхние 2 и нижние 3 дисковые ножи диаметром D и шириной Ьк с режущими кромками 4 и коническими поверхностями 5, а также дополнительные диски 6 диаметром D, расположенные на противоположных концах верхнего и нижнего валов устройства и имеющие конические поверхности 7. Расстояние между дисковыми ножами 2 и 3 и дисками 6 равно I, а величина перекрытия ножей равна δ. Угол φ конуса конических поверхностей 5 и 7 равен 20...25°. Высота образующей боковой поверхности 8 цилиндрической формы дисковых ножей 2 и 3 и дисков 6 равна (0,15...0,2)1.A device for the longitudinal separation of rolling stock contains installed on the upper and lower shafts 1 of the upper 2 and lower 3 circular knives with a diameter D and a width b with cutting edges 4 and conical surfaces 5, as well as additional disks 6 with a diameter D located at opposite ends of the upper and lower the device shafts and having conical surfaces 7. The distance between the disk knives 2 and 3 and the disks 6 is equal to I, and the overlap value of the knives is equal to δ. The angle φ of the cone of conical surfaces 5 and 7 is 20 ... 25 °. The height of the generatrix of the lateral surface 8 of the cylindrical shape of the disk knives 2 and 3 and the disks 6 is (0.15 ... 0.2) 1.
Устройство работает следующим образом.The device operates as follows.
При заходе в устройство раската, состоящего из трех овалов 9, соединенных перемычками, металл захватывается вращающимися дисковыми ножами 2 и 3, в результате чего ножи 2 и 3 перерезают режущими кромками 4 перемычки между овалами. Одновременно вследствие контакта овалов с поверхностями 5 и 7 ножей и дополнительных дисков 6 происходит по5 ворот поперечных сечений овалов 9 раската.When you enter the device roll, consisting of three ovals 9 connected by jumpers, the metal is captured by the rotating disk knives 2 and 3, as a result of which the knives 2 and 3 are cut by the cutting edges 4 of the jumper between the ovals. At the same time, due to the contact of the ovals with the surfaces of the 5 and 7 knives and additional disks 6, 5 gates of the cross sections of the ovals 9 of the roll occur.
