Gap control device for pilger die assembly of cold pilger mills

摘要

A gap control device for a Pilger die assembly of cold Pilger mills. The gap control device can independently control the height of a pair of bearing blocks which axially support an upper die. A lower plate 110 has first and second receiving holes 111,112 which respectively correspond to the upper portions of a pair of bearing blocks. First and second wedge plates 120, 130 are fitted into the receiving holes, and respectively have inclined surfaces on the upper portions thereof. First and second adjustment blocks 140, 150 respectively have inclined guide surfaces to be in surface contact with the inclined surfaces of the wedge plates, and are movable horizontally with respect to the lower plate. An upper plate 160 is assembled to the upper portion of the lower plate to cover the adjustment blocks. First and second adjustment bolts 170, 180 allow the first and second adjustment blocks to be respectively manipulated in a horizontal direction.
