Abstract
PURPOSE: The die for presses which comprises providing plural non-contact displacement gauges on the die plate lower die of the press die and disposing targets to the upper die punch plate and which is capable of measuring relative vibrations in the horizontal directions and knowing the dynamic accuracy of the press machine, such as deflection of the frame, etc.
CONSTITUTION: Plural non-contact displacement gauges 2, 3 are mounted to the die plate 1 of the lower die I of the press die and targets 6, 7 are mounted to the punch plate 4 of the upper die II to measure the relative vibrations of the upper die with respect to the lower die. The non-contact displacement gauges convert the distances between the targets and sensors to voltages in the absence of contact by making use of eddy currents, electrostatic capacities, etc.
