SYNCHRONIZING / TUNING SYSTEM, SYNCHRONIZATION AND TUNING METHOD AND SYNCHRONIZATION AND TUNING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a synchronous tuning system of a multiple press device, a synchronous tuning method, and a synchronous tuning program which enable high-precision synchronous tuning between press devices connected sideways to carry out high-precision bending work on a long workpiece by an operation.SOLUTION: In at least two points of respective rams of a plurality of press devices 100-1, 100-2 connected sideways in a width direction. Positions in vertical directions of the rams 111, 112 are detected by a plurality of ram position detection means 141a, 141b, 142a, 142b, respectively. With reference to a detection position of the ram position detection means 141a, a ram position detection positional deviation at another detection point is calculated. AC servo motors M1, M2, M3, M4 are servo-controlled, respectively, so as to correct vertical positions of rams at the respective detection points on the basis of the calculated ram position detection positional deviation.
