摘要： PURPOSE:To change rolls at optional cross angle by mainly constructing a means for supporting a connecting part with a cross assembly of a means for moving the supporting point of a carrier of a spindle and of a means for stretching and contracting the spindle in the axial direction. CONSTITUTION:A traverse frame 22 is driven by a hydraulic cylinder to slide on the top surface of an up-and-down frame 21 so that a slide frame 24 is positioned at right under the supporting part of a cross assembly 2. The up-and- down frame 21 is lifted by the hydraulic cylinder 27 and the frame 24 supports the cross assembly 2. Then, the axial direction of the spindle is adjusted to an angle corresponding to a roll crossing angle by the hydraulic cylinder. Fastening bolts between the cross assembly 2 and a coupling 3 are removed to contract the spindle and to separate the cross assembly 2 from the coupling 3. After changing rolls with a new coupling 3 and roll chocks, the coupling and cross assembly 2 are connected in procedures reversing to the above procedures.

摘要： PURPOSE:To improve mechanical efficiency and to permit easy carrying in and out of a material by disposing one of the driving systems for rolling rolls of a crossing type cross helical rolling mill on the inlet side of a pass line and disposing the other driving system on the outlet side of the pass line. CONSTITUTION:Roll shafts 3, 3' of the crossing type cross helical rolling mill are disposed to face each other in such a manner that the side shafts incline at a required angle with the pass line L at the center of rolling rolls 5, 5' when viewed laterally and cross at an angle alpha with the line L when viewed from the plane. The driving system for the roll 5 consisting of a driving motor 6 and a reduction gear 7 is provided on the counter roll 5 side and the inlet side of the roll and the driving system for the roll 5' consisting of a motor 6' and reduction gear 7' is provided on the roll 5' side of the line L and on the outlet side of the line. The setting range of the crossing angle alpha is thus widened and the combined angle of the cross pin part of universal joint parts 9, 9' is made small. The mechanical efficiency of a piercer is thereby improved and the carrying in and out of the material is made easy.
