MANDREL RESTRAINING ASSEMBLY FOR A TUBE-ROLLING MILL |
摘要 |
<p>A restraining assembly for holding back and then releasing a mandrel which supports a tube being rolled in a rolling mill has a fork supported by a carriage which is driven by two endless chains. The carriage is articulated to two opposite links of the chains and the separation of the fork from the mandrel takes place as the chains run round end wheels and the carriage is tilted. To control this movement of the carriage the fork is at the forward or downstream end of the carriage and an additional connection is provided between the carriage and another link of at least one chain, preferably with play in the direction of movement of the chain.</p> |
