摘要： PROBLEM TO BE SOLVED: To allow a rotary shaft to be smoothly rotated at a constant angle in the range of total angles by pressing the rotary shaft by means of a bark and forth moving driving cam. SOLUTION: A sliding stepped face 6 is formed to be projected at one end part of a cutout face 5 formed in the direction of a hypotenuse at a part of the outer periphery 2 of a rotary shaft 1, and an inclined cam face 13 of a driving cam 11 is pressed against the sliding stepped face 6 to be slid to rotate the rotary shaft 1 through a constant angle. First, the inclined cam face 13 of the forth moving driving cam 11 is pressed against an outside step edge (e) of the sliding stepped face 6 to rotate the rotary shaft 1. After the inclined cam face 13 comes into surface contact with the sliding stepped face 6, an inward step edge (f) of the sliding face 6 is pressed n the course of the inclined cam face 13 to rotate the rotary shaft 1 up to a final angle.

摘要： PROBLEM TO BE SOLVED: To exchange upper and lower roll units without using a crane with high efficiency. SOLUTION: A roll unit exchanging device 1 for roller leveler 100 comprises a unit pulling-out/pushing-in device 10, a unit carrying truck 20 which individually ascends and descends upper and lower roll units 101, 102 and at the same time executes reciprocating traveling along rails 2, 2 in parallel to a roll shaft, a lower roll unit transversely transferring device 30 and an upper roll unit transversely transferring device 40 which execute reciprocating travelling between an end side repairing position and a center position of the unit carrying truck 20 on an inner/outer side shift base 3, 3, 4, 4 intersecting at right angles with rails 2, 2, a unit turning device 50 which is located outside the outer side shift base 4, 4 and rotates the upper roll unit, and a unit rotation preventive device 60 to prevent rotation of upper roll unit after rotation. Thereby, the upper/lower roll unit 101, 102 are changed with high efficiency without using a crane.

摘要： PROBLEM TO BE SOLVED: To shorten the time of a roll changing and to reduce the down time of a line by installing an upper straightening roll unit reversing device on a roll changing device which takes in and out a straightening roll unit from a housing. SOLUTION: When an upper straightening roll unit 10 is changed, it is drawn from a housing 21 by moving a changing carriage 33 to the working side on a changing rail 32 with a drawing cylinder 38, the upper straightening roll unit 10 is reversed by loosening both side bolts 6, 13 releasing fixing of bearing blocks 3, 10 with blocks 7, 8 and turning stoppers 5, 12, rotating a worm 15 with a handle 16 and turning a worm gear 14 and a bearing 9 by about 180 deg., and the upward faced roll assembly can be changed. Because the carrying time is made without requiring on the result, the down time of the line caused on the roll re-changing can be shortened.
