摘要

"The control process of Roller Hydraulic Pullers and control unit roller hydraulic pullers.A control unit Roller Hydraulic Pullers (1) comprises: position detectors (10c,10d) that detect the position of the pistons of cylinders (6c) right and left; an arithmetic unit (13) which calculates a difference of output (16C.16d) of the detectors of position; a controller (14) which processes a calculated value for performing correction of output; and units of add subtract (18C,E) that add / subtract the output of the correction of the controller so that the output of correction (17) is added to a top of the rolls handles having a wider range in a direTion to reduce the interval and the output correction (17) is added to a top of the cylinder having a wider range handles in a direction to reduce the interval and the output corr in the overview listTo the same value is subtracted from the extreme opposite party, which is why the pre-determined values of force control for pressing provided with right and left independently are corrected.Thus, a profile of coil winding defective can be deleted.
