Abstract

Заявленное изобретение относится к кассете-держателю валков для прокатного стана (20). Кассета (24) содержит две торцевые стенки (26), совокупность блоков "валок-рычаг" (30), два стопорных кольца (28) и стопорный привод (32). Каждая торцевая стенка кассеты содержит совокупность первых гнезд (260); каждое стопорное кольцо содержит совокупность вторых гнезд (280); а каждый из блоков "валик-рычаг" установлен на кассете таким образом, чтобы обеспечить вращение вокруг штифта (300), при этом каждый конец каждого штифта заключают в осевом направлении внутри первого гнезда и второго гнезда соответственно. Кроме этого, первые гнезда позволяют осуществлять смещение соответствующих штифтов в чисто касательном направлении t;вторые гнезда позволяют осуществлять смещение соответствующих штифтов в чисто радиальном направлении r; а два стопорных кольца могут вращаться вокруг оси X при помощи стопорного привода. Изобретение также относится к прокатной клети (22), содержащей вышеописанную кассету и прокатный стан, содержащий совокупность прокатных клетей (22).The claimed invention relates to a roll holder for a rolling mill (20). The cassette (24) contains two end walls (26), a set of roll-lever blocks (30), two retaining rings (28) and a locking drive (32). Each end wall of the cassette contains a set of first sockets (260); each circlip contains a plurality of second sockets (280); and each of the roller-lever units is mounted on the cassette so as to rotate about the pin (300), with each end of each pin being axially enclosed within the first socket and the second socket, respectively. In addition, the first sockets allow displacement of the respective pins in a purely tangential direction t; the second sockets allow displacement of the respective pins in a purely radial direction r; and the two retaining rings can be rotated around the X-axis by means of a locking drive. The invention also relates to a rolling stand (22) containing the cassette described above and a rolling mill containing a plurality of rolling stands (22).
