Изобретение относится к прокатному производству и может быть использовано для защиты рабочих клетей прокатных станов от перегрузок. Предлагается предохранительно-разгрузочное устройство прокатной клети с разрушаемым элементом, которое установлено между нажимным средством и подушкой прокатного валка и включает пуансон, бандаж и основание, образующие рабочую полость, заполненную эластомером. Бандаж выполнен в виде двух полуколец, один конец которых связан с другим срезным пальцем, а другой - шарниром, ось вращения которого параллельна оси нажимного средства, причем срезной палец установлен на концах полуколец в срезающих втулках, а ось срезного пальца параллельна оси нажимного средства или перпендикулярна ей. Устройство снабжено ограничителем перемещений, выполненным в виде цилиндра, жестко связанного с пуансоном, и установленным по оси нажимного средства. В боковой стенке одного из полуколец выполнено сквозное радиальное отверстие с резьбой, в которое вкручен болт. В случае заклинивания валков выход эластомера через отверстие при выкручивании болта позволяет разгрузить клеть и развести валки. Заявленная совокупность отличительных признаков обеспечивает конструктивную простоту, компактность и удобство в обслуживании устройства, что снижает продолжительность аварийных простоев стана и трудоемкость восстановительных работ.The invention relates to rolling production and can be used to protect the working stands of rolling mills from overload. A safety-unloading device for a rolling stand with a destructible element is proposed, which is installed between the pressing means and the rolling-roll cushion and includes a punch, a bandage and a base, forming a working cavity filled with elastomer. The bandage is made in the form of two half-rings, one end of which is connected to the other shear finger and the other hinge, the axis of rotation of which is parallel to the axis of the pressing means, the shear finger is mounted on the ends of the half-rings in the shearing bushings and the axis of the shear finger is parallel to the axis of the pressing means or perpendicular her. The device is equipped with a movement limiter, made in the form of a cylinder rigidly connected with the punch, and mounted along the axis of the pressing means. In the side wall of one of the half-rings there is a through radial hole with a thread into which a bolt is screwed. In the case of seizure of the rolls, the elastomer exit through the hole when unscrewing the bolt allows unloading the cage and spreading the rolls. The stated set of distinctive features provides constructive simplicity, compactness and ease of maintenance of the device, which reduces the duration of emergency downtime of the mill and the complexity of restoration work.
