Abstract

PURPOSE:To obtain the titled rolling roll unit possible to efficiently produce the good product, by forming the stepped part in the trunk of the horizontal roll and in the top and bottom faces of the vertical roll, so as to make these two rolls contact and engage at this stepped part when the zero point of two rolls is to be adjusted, and by quickly adjusting their zero point. CONSTITUTION:The universal rolling roll unit is constituted as follows; in the trunks of the horizontal rolls 1, 1, and in the upper and lower faces of the vertical roll 2, the mutually fittable stepped part A (inclined stepped shape) and B (end face chamfered shape) are formed so as to make two rolls 1, 2 contact and engage mutually when their zero point is adjusted. Said shapes A, B of the stepped parts are not defined to the above-mentioned shapes, but both shapes have to be made mutually fittable. The distance L from the roll surface of the horizontal roll 1 to the stepped part A, and the distance L from the longitudinal middle point of the vertical roll 2 to the stepped part B, are made equal. By this roll unit, the upper and lower, and the left and the right rolls can be exactly and quickly set at the specified positions.
