JPS5561316A - Entrance guide unit for indentation mill - Google Patents

Abstract

PURPOSE: To shorten the stroke of the pusher, and to reduce the installation cost, by arranging in the entry side pass line of the indentation mill the entirely surrounding type guide whose at least one side plane guide can be freely opened and shut.

CONSTITUTION: On the entry side of the reducing rolls 1, 1', the guide roller queues es 2W5 being supported by halved guide blocks 6, 7, are arranged so as to surround the pass line. The roller queues 2, 3, go up to the position 7' as shown by the oblique line through the cylinder 8, the link mechanism 9, and the block 7, and opens the receptacle for the material to be rolled. The material 11 is carried in by the roller table 10, the block 7 is moved down, and the material 11 is carried in by the roller table 10, the block 7 is moved down, and the material 11 is indented into the rolls 1, 1', by the transversal movement of the pusher head 14. If the length of the material to be rolled is taken as L, the distance from the mill center B-B to the outer surface of the roll post and to the entrance end of the guide are taken respectively as M, N, and the working tolerance is taken as α, the pusher stroke is N+ L+α by the conventional method, and M+L+α by this method; for example, if L is 5m, the pusher stroke can be shortened by about 9m according to this method.
