PRESS MACHINE BRAKING PERFORMANCE VERIFYING APPARATUS

摘要

A press machine braking performance verifying apparatus verifies performance of brakes applying braking to a slide. The press machine braking performance verifying apparatus includes a speed detecting component, a stopping instruction detecting component, a stopping time measuring component, a maximum stopping time calculating component and an evaluating component. The speed detecting component detects a slide driving speed. The stopping instruction detecting component detects if stopping of the slide is instructed. The stopping time measuring component measures a stopping time until the slide stops when a stopping instruction is detected. The maximum stopping time calculating component calculates predicted stopping time in a case where the slide is driven at a maximum driving speed based on the slide driving speed after detecting the stopping instruction and the stopping time. The evaluating component evaluates performance of the brakes by comparing the predicted stopping time and a threshold valve set in advance.
