Abstract

DC60 The large diameter difference of the intermediate rollers (20, 21) in a six-ply structured compacting press with a rolling area of x3 will cause more wear and cause the supporting rollers (30, 31) to have a rough surface in practice, resulting in a damaged condition on the support rollers (30, 31) after a long time of operation, consistent with the geometry of the rolling area CVC, the initial rolling area width is also much larger than that required for the workpieces rolled on a four-ply press, which will also cause the supporting rollers to have a worn condition, which is undesirable. To minimize the defect, it is proposed according to the characteristics of the invention herein that the roller axis length (L) of every intermediate roller (20, 21) in a six-ply compacting press and/or of every working roller in a four-ply compacting press comprises the span of the axis. Cylindrical rollers (Z) and the span of the convex roller axis (R(x)), where the transition point (A) from the span of the convex roller axis to the cylindrical roller axis can be selected in the range L/2 < = x < L, and the arc-shaped outline extending on the two rollers (20, 21) to opposite sides on a portion of the width of the roller bar in the direction towards the end of the roller axis, which is described by the mathematical polynomial R(x) = a0 + ... + anxn, where n > = 5. The large diameter difference of the intermediate rollers (20, 21) in the six-layer structure compacting press with a rolling area x3 will cause more wear and make the supporting rollers (30, 31) have a rough surface. In practice, the damage condition on the supporting rollers (30, 31) occurs. After a long time of operation, consistent with the shape of the rolling area CVC, the initial rolling area width is larger than that required for the workpieces compacted on the four-layer press. This is also very likely to cause wear on the support rollers, which is undesirable. To minimize this defect, it is proposed, according to the embodiment of the invention, that the length of the roller axis (L) of every intermediate roller (20, 210) in a six-roll press and/or of every working roller in a four-roll press comprises a range of cylindrical roller axis (Z) and a range of convex roller axis (R(x)), such that a transition point (A) from the range of cylindrical roller axis to convex roller axis can be selected in the range L/2 < = x < L and a curved outline extending on both rollers (20, 21) to opposite sides over a portion of the roller bar width in the direction towards the roller axis ends is described by a mathematical polynomial R(x) = a0 +...+ anxn, where n > = 5.
