Abstract

PURPOSE:To calculate the eccentric load automatically and measure the accurate eccentric load in a short time, by disposing rotation range detecting means, maximum load detecting circut, eccentric load detecting circuit, alarm signal issuing and machine stopping means etc. CONSTITUTION:A rotation range detector 10 is provided in a crankshaft (not shown) on which are mounted right and left rods 2, 3 of a press slide 1. By the signal therefrom, the detector 10 is closed in an allotted measuring cycle. By a command St from a timing circuit 9, the initial load value is subtracted from the maximum load value in a maximum load detecting circuit 14 and a subtraction unit 15, and the true maximum load value is calculated (separately for each side). By substracting the maximum load value in a substraction unit 19 through registers 17, 18, the eccentric load value is determined, and sent into a memory 20. In a comparator circuit 21, said eccentric load value and the set point in a setting device 22 are compared. When exceeding the set point, an alarm is issued to an alarm unit 22 or the pressing machine is stopped.
