Squeeze roll stand

摘要

A squeeze roll stand includes a combination of a fixed portion installed at a joint position of an electric resistance welded pipe manufacturing line, in which squeeze rolls excluding left and right upper rolls are detachably assembled, and a movable portion overlying the fixed portion, inside which left and right upper rolls are detachably assembled, the movable portion being inclined, taking a back surface downstream side as a fulcrum point, toward a same side from an assembling position on the fixed portion to a retreat position to open an upper part of the fixed portion. The movable portion is driven and reciprocated between the assembling position and the retreat position with cylinder type actuators as a drive mechanism. At the retreat position, the movable portion overlies a bead grinding device arranged on the back surface downstream side of the fixed portion with a front surface facing upward.

主权项

1. A squeeze roll stand comprising:
a fixed portion installed at a joint position of an electric resistance welded pipe manufacturing line, in which squeeze rolls, excluding left and right upper rolls, are detachably assembled; a movable portion overlying the fixed portion, inside which the left and right upper rolls are detachably assembled, the movable portion being pivoted toward a line downstream side of the fixed portion taking an upper end of the line downstream side of the fixed portion as a center so that the movable portion is tilted from an assembling position on the fixed portion to a retreat position to open an upper part of the fixed portion with the line downstream side as a pivot; a lock mechanism for fixing the movable portion at the assembling position on the fixed portion; and a drive mechanism for driving and reciprocating the movable portion between the assembling position and the retreat position; wherein the fixed portion is combined with a bead grinding device installed on the line downstream side, and the movable portion overlies the bead grinding device with a front surface thereof facing upward in a state that the movable portion is tilted toward the retreat position on the line downstream side.
