Description
В промышленности используютс трехвалковые раскатные станы дл прокатки труб на длинной оправке, котора имеет большой вес. Известно и применение плавающей оправки при холодном волочении труб из черных и цветных металлов. Однако известные способы осуществл ютс с большим расходом инструмента и при с.ложной настройке стана.The industry uses three-roll mills for rolling tubes on a long mandrel that is heavy. Known and the use of a floating mandrel for cold drawing pipes from ferrous and non-ferrous metals. However, the known methods are carried out with a large consumption of tools and with a simple setup of the mill.
Особенность описываемого способа состоит в том, что, с целью упрощени установки стана, сокращени расхода инструмента и увеличени диапазона размеров приготовл емых труб, прокатка ведетс на плаваюи ей короткой оправке с уДоТиненным передним концом.The peculiarity of the described method is that, in order to simplify the installation of the mill, reduce the tool consumption and increase the size range of the prepared tubes, rolling is carried out on the floating short mandrel with a verified front end.
Описываемый способ прокатки труб осушествл етс на трехвалковом стане на плавающей короткой оправке.The described pipe rolling method is carried out on a three-roll mill on a floating short mandrel.
На фиг. 1 показана схема прокатки , где: /-гильза-труба, 2- валок, .3-плавающа оправка. Оправка делаетс с удлиненным передним концом, который перед прокаткой вводитс в выводную проводку и центрователь, пока торец его не достигает установочногоFIG. Figure 1 shows the rolling pattern, where: / - liner-tube, 2- roll, .3-floating mandrel. The mandrel is made with an elongated front end, which, before rolling, is inserted into the lead-through wiring and centering until its end reaches
упора на выходно стороне стана. Помещение переходного конца оправки в выводной проводке и центрователе обеспечивает поддержание без большого провисани оправки между валками перед прокатко . Наличие упора позвол ет устанав.тивать и удерживать оправку в начале прокатки в требуемом положении между ва.тками по оси п|)окатки.emphasis on the output side of the camp. The placement of the transition end of the mandrel in the lead wiring and centering unit ensures that the mandrel is held between rolls before rolling without much sagging. The presence of the stop allows you to set and hold the mandrel at the beginning of rolling in the desired position between the wafers along the n axis)).
На фиг. 2 показана схема конечного момента прокатки с подъемным упором, где: 4-валок, 5-плавающа оправка, 6-труба, 7-качающийс упор, 8-цилиндр упора, 9-запирающий клин и W-цилиндр привода запирающего клина.FIG. Figure 2 shows a rolling end point diagram with a lifting stop, where: 4-roll, 5-floating mandrel, 6-tube, 7-swing stop, 8-cylinder stop, 9-locking wedge and W-cylinder of the locking wedge.
После того, как процесс прокатки установитс , упор убираетс и прокатывае1 а труба свободно выходит из стана.After the rolling process is established, the stop is removed and rolled, and the tube leaves the mill freely.
