Abstract
The invention is embodied in a tube cutting station in a tube producing mill. The cutting station includes a rotating press assembly and an axially moving cutting assembly. The cutting assembly is accelerated axially to a velocity which matches that of the tubing being produced. Once the cutting assembly reaches the same velocity as the tubing line, the press assembly can cause downward movement of a cutting blade through the tubing. The press assembly of the present invention is alternately rotated in opposite directions to maximize the rotational extent and time available for acceleration and deceleration of the press assembly, and therefore enables the use of lightweight drive motors. Slower acceleration and deceleration also reduces wear on components used to drive and stop the press assembly.
