Abstract

Изобретение относитс к обработке металлов давлением, а именно к устройствам дл получени трубных заготовок. Цель изобретени - снижение металлоемкости и повышение качества получаемых изделий. При включении рольгангов труба подаетс до упора. При подходе к упору включаетс датчик 31 и труба подходит к ползуну 18 до соприкосновени с ним. Собачка 20 оказываетс внутри трубы 30. В бесштоковой полости ступени 29 силового цилиндра 25 снимаетс давление, и ползун 18, перемеща сь в направл ющих 22, прижимает трубу 30 за внутреннюю сторону стенки собачкой 20 к корпусу 23. После отрезки заготовки в бесштоковые полости ступеней 28 и 29 силового цилиндра 25 подаетс давление. Ползун 18 разжимает трубу 30 и при выходе из направл ющих 22 поворачиваетс на 90°, выход из зоны перемещени трубы. 4 ил.The invention relates to the processing of metals by pressure, in particular to devices for the production of tubular blanks. The purpose of the invention is to reduce the metal content and improve the quality of the products. When the live rolls are turned on, the pipe is fed to the stop. When approaching the stop, sensor 31 is turned on and the pipe approaches slide 18 until it is in contact with it. The dog 20 is inside the pipe 30. In the rodless cavity of the step 29 of the power cylinder 25, pressure is relieved, and the slide 18, moving in the guides 22, presses the pipe 30 on the inside of the wall of the dog 20 to the housing 23. After cutting the workpiece into the rodless cavities of the steps 28 and 29 ram 25 is pressurized. The slider 18 expands the pipe 30 and when exiting the rails 22 rotates 90 °, the exit from the zone of movement of the pipe. 4 il.

Claims

SUMMARY OF THE INVENTION '• Pipe cutting line, comprising a loading device with a piece-by-piece dispensing mechanism, a feeding roller table with clamps, a cutting machine, a receiving roller table with an emphasis, a ejector and a baling device, which are designed to reduce metal consumption and increase the quality of the products obtained, the emphasis is made in the form of a roller installed on the receiving roller with the possibility of limiting movement of the body with an axis ² * and guides, a slider with a through / groove installed with the possibility of translational movement in guides of the housing and rotation around an axis located in the groove of the slider installed in the housing of the double power cylinder pivotally connected to the slider by means of an individual U axis mounted on one end of the slide with an offset relative to the axis of the housing, and a spring-loaded dog mounted on the other end of the slide with side of the feed roller table.
