Abstract

PURPOSE: To surely extract the pipe material from the mandrel, by continuously moving forward the rolled pipe material after passing over the rolling mill, and by holding the mandrel unit the rolled pipe is separated from the mandrel, and then, by releasing the mandrel.
CONSTITUTION: Under the condition 1, the mandrel rod 13 is ready to be inserted into the pipe material 14, at the starting point of the working cycle. Under the condition 2, the mandrel 13 is inserted into the pipe material 14, and the mandrel 13 together with the pipe material 14 are transferred onto the rolling mill 4. Under the condition 5, the rear end of the pipe material 14 is also bitten into the two stage roll stand 41 of the rolling mill 4. Under the condition 7, the mandrel is held until the extractor roll 7 finishes the extraction of the pipe material 15. At the moment that the rear end of the pipe mateial 15 passes over, the driver 6 catches the mandrel, and when the drawn pipe material 15 is transferred onto the roller table 9 for receiving the pipe material, the driver 6 moves, after the mandrel transfer block 12 is released, so as to drive the mandrel out of the rolling mill.
