<P>PROBLEM TO BE SOLVED: To provide a squeeze roll stand with which the squeeze rolls can be exchanged easily, and which has a simple equipment configuration. <P>SOLUTION: 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 right/left 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 right/left 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 a 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 part facing upward. <P>COPYRIGHT: (C)2013,JPO&INPIT |
