ABSTRACT:
The disclosure is directed to improvement in stretch reducing mills utilized in the manufacture of seamless and welded tubing. The stretch reducing mill is well known in its generalities, and the disclosure is directed to improvements in the construction of such mills in the interest of increasing the efficiency of operation and performance of the mill. The disclosure is directed in part to the construction of a multi-stand stretch reducing mill with improved arrangements for removably securing the individual mill stands in position. This includes a heavy, massive structural beam from which all of the individual mill stands are suspended and which additionally serves, when the mill is ready for operation, as a means for holding the mill stands in position. In the latter capacity, the beam contributes both in terms of its great weight and in terms of distributing clamping forces to the individual mill stands from a limited number of clamps. The mill also includes an improved arrangement for longitudinally clamping together a series of consecutive mill stands, using a combination of hydraulic clamping cylinders and a mechanical fail-safe system, enabling the advantages of hydraulic clamping to be enjoyed while avoiding any serious consequences from untimely failure of hydraulic pressure. An additional feature of advantage included in the disclosure is an improved mechanism for effecting simultaneous coupling and decoupling of the individual mill stands to their respective individual drive motors.
