Abstract

Изобретение относитс к обработке металлов давлением, в частности к валковым гибочным устройствам. Цель изобретени - повышение надежности и снижение энергоемкости. На станине 1 в стойках 2 и 3 установлены боковые валки 4,5, а также верхний валок 6. Верхний валок 6 смонтирован с возможностью осевого перемещени . Устройство осевого перемещени верхнего валка 6 включает шестерню 12, внутри которой размещен корпус 10, несущий ролики 8. Ролики установлены на ос х, расположенных под углом к оси верхнего валка. Шестерн входит в зацепление с зубчатым колесом 13, которое муфтой 15 соединено с главным приводом. В устройство осевого перемещени верхнего валка 6 вход т также толкатель 20, диски 21, кольцевые упоры 24,25 и командоаппараты 26 и 27. Перед началом гибки толкатель через диски перемещает шестерню 12 вправо вдоль оси валка 6 и выводит ролики 8 из зацеплени с цилиндрической поверхностью валка. После окончани гибки отключаетс электромагнит толкател . Через муфту от главного привода приводитс во вращение колесо 13. От колеса 13 вращаетс шестерн 12, котора увлекает за собой корпус 10 с размещенными в нем роликами 8. Ролики, контактиру с валком 6, перемещают его в осевом направлении до выхода из зоны гибки. 1 з.п. ф-лы, 5 ил.The invention relates to the processing of metals by pressure, in particular to roller bending devices. The purpose of the invention is to increase reliability and reduce energy consumption. On the bed 1 in the racks 2 and 3 side rolls 4,5 are installed, as well as the upper roll 6. The upper roll 6 is mounted with the possibility of axial movement. The device for the axial movement of the upper roll 6 includes a gear 12, inside which is placed the housing 10 carrying the rollers 8. The rollers are mounted on axles angled to the axis of the upper roll. Gear engages with a gear wheel 13, which coupling 15 is connected to the main drive. The pusher 20, the disks 21, the ring stops 24.25, and the command gears 26 and 27 also enter the axial movement of the upper roll 6. Before the bending is started, the pusher moves the gear 12 to the right along the roll axis 6 and drives the rollers 8 out of engagement with the cylindrical surface roll. After the bending is completed, the push rod electromagnet is disconnected. Through the coupling from the main drive, the wheel 13 is rotated. A gear 12 rotates from the wheel 13, which carries the body 10 with the rollers 8 placed in it. The rollers, in contact with the roller 6, move it in the axial direction until it leaves the bending zone. 1 hp f-ly, 5 ill.
