Document Type and Number:

WIPO Patent Application WO/2012/144090

Kind Code:

A1

Abstract:

Provided is a squeeze roll stand with which the squeeze rolls can be exchanged easily, and which has a simple equipment configuration. This squeeze roll stand, which is arranged in a junction location of an electro-resistance welded tube manufacturing line, is constructed by combining a stationary unit (10), in which the squeeze rolls are incorporated such that the squeeze rolls, excluding the left/right upper rolls, can be removed, and a movable unit (20), which is placed on top of the stationary unit (10), and in the interior of which the left/right upper rolls are incorporated in a removable manner, and which, with the back side (the downstream side of the line) as the pivot point, tilts from its assembled position on top of the stationary unit (10) to a retracted position toward the back side, which opens the top of the stationary unit (10). The movable unit (20) moves reciprocally between the assembled position and the retracted position with cylinder-type actuators (24) as the drive mechanism (40). In the retracted position the movable unit (20) lies atop bead grinding equipment (50), located on the back side (the downstream side of the line) of the stationary unit (10), with the front face of the movable unit facing upward.
