TH23869B - Curvature correction equipment for the soft rolling and pressing of metal sheets. - Google Patents

Abstract

Curvature device for rolling and pressing of soft metal sheets. Vertical of cold-rolled steel sheet The curvature corrector consists of at least the first auxiliary curvature roller, the first corrugating roller, the second correcting roller, and the auxiliary roller used. Correct the second curvature, these balls are aligned with the running direction of the cold rolled steel plate alternately placed on top. And the bottom of the cold rolled steel plate to solve the bending of the steel plate.

Claims (4)

1. Curvature correction equipment (7) for soft metal rolling and compacting machines, rolling and compacting machines. The malleable metal consists of a rotating guide roll (8) and a rolling stand (5) with a rolling pin (6), a rolling pin (8) positioned below the rolling mill roller (6). ) In the running direction of the cold-rolled steel plate (3,3a); The curvature corrector (7) consists of a pair of auxiliary metal rolling rollers (11,12) located between Rolling mill rollers (6) and rolling force rolls (8); In such a way that The curvature auxiliary roller (11,12) is vertically raised and the cold-rolled steel plate (3a) is in contact with the line segment. The loop of that pair of reinforced metal rolling rollers (11,12) is used to correct the bending of the cold rolled steel plate (3a) when at least One of those pairs of auxiliary metal rolling rollers is used to correct that curvature (11, 12) is raised vertically. And have a look at The curvature corrector (7) consists of a large number of rolling rollers. The metal that serves to transform the corridors (13,14) that are located between them. Of the reinforced metal rolling rollers used to rectify the curvature (11,12), that large number of the five turning rollers (13,14) correcting the running direction of the cold rolled steel plate (3a ) That pair of curvature rollers (11,12), and many of the rolling rollers acting on the corridor (13,14) were arranged in the running direction of the rolled steel plate. Cold rolled (3a) in such a way that the curvature auxiliary rollers (11, 12), and that large number of rollers acting on the path (13, 14) are alternately placed on the top surface. And the lower surface of the sheet steel Through cold rolling (3a) 2. The curvature corrector according to claim 1. Where that pair of auxiliary rolling rollers are used to correct the curvature (11, 12) and that large number of rolling rollers that act. Changing passageways (13, 14) are placed far apart and the conditions are as follows. 1.5 < -L2 / D < -3, and 1.5 < -L4 / D < -3, where L is the horizontal distance between the lower point of the auxiliary metal rolling roller used to correct the curvature (11) of That pair of reinforced metal rolling rollers used to correct the curvature. Adjacent to the rolling roller (6) and the rolling roller that serves to change the path (13) of that bulk of the rolling roller. That serves to change the corridors Near the door to the rolling mill roller (6), L4 is the distance along the Lie between the middle point of the other (12) of that pair of curvature auxiliary rolling rollers closest to the roll (8) and the other roller (14) of that bulk of the ball. Rolling metal that serves to change the path Which is closest to the rolling force roll (8) and D is the diameter for each of that pair of curvature rollers (11, 12). 1. or 2 where that pair of reinforced metal rolling rollers at It is used to rectify the curvature (11,12), and that large number of rolling rollers acting as turning the corridor (13,14) is also conditional as L1 / D > -3, and L5 / D > -3, where L1 is the horizontal distance between the bottom of the rolling mill roller (6) and the additional curvature roller (11) close to the rolling mill roller (6), L5 is the distance according to Horizontally between the bottom of the roll (8) and the auxiliary metal roller used Solve that other curvature (12) which is closest to the roll (8), and D is the diameter. For each of that pair of additional metal rolling rollers used to rectify the curvature (11,12) 4.Correction device according to claim 1., 2. or 3. Where a lot of things The corridor-changing metal rolling mill (13,14) revolves around a fixed central shaft 5. The malleable metal rolling and compacting machine, the malleable metal rolling and compacting machine consists of: Rolling stands (5) with metal rolling rollers (6); And the turning force roll (8) located underneath the metal rolling mill (6) in the running direction of the cold rolled steel plate (3,3a) in such a way that the curvature corrector (7) as Specified in any of the Clause 1. to 4.It is placed between the rolling mill roller (6) and the rolling guide roll (8).
