Abstract

PURPOSE:To make possible the different kind of square bars to be easily guided, by installing the rotatable guide frame provided with plural guide unit including different kinds of guide rollers, in the guide unit on the entry side of the piercing mill. CONSTITUTION:The square bar 1 is transported and is inserted into the specified guide unit, and the transfer frame 15 is brought down through the lever 17; hereby, the square bar 1 is placed on the horizontal guide roller 4a. The feed guide roller 5 is actuated through the lever 14 so as to guide the right side plane of the square bar 1; at the piercing work, the square bar 1 is surely caught and guided onto the specified pass line by the vertical guide roller 3a, horizontal guide roller 4a, and feed guide roller 5. In the case of guiding the square bar 1 of different size, the feed cylinder 10 is actuated so as to retreat the feed guide roller 5, and the guide frame 13 is turned round to the desired position so as to use the guide unit suitable for the size of the square bar 1.
