Title:
METHOD FOR CONTROLLING SHAPE OF PIPE BY REELER
Document Type and Number:
Japanese Patent JPS5976608
Kind Code:
A
Abstract:

PURPOSE: To control highly accurately a shape of pipe rolled by a reeler, by adjusting a torque difference between motors for driving both rolls by field adjusting relatively roll driving motors for driving rolls respectively to adjust the torque difference of the motors for driving both rolls, and controlling the expanding rate of a blank pipe.

CONSTITUTION: A blank pipe 14 is reeler-rolled by a plug 13 and two rolls 11, 12 in a state that the pipe 14 is supported at three points by the rolls 11, 12 and a shoe 15, by deviating the pass line of blank pipe 14 from a minimum roll gap position fixed by the center axes of the two rolls 11, 12. At that time, a torque difference between motors 11A, 12A for driving both rolls is adjusted by field adjusting relatively both motors 11A, 12A for driving respectively both rolls, thereby an expanding rate of the pipe 14 is controlled.
