UPPER DIE WEIGHT MEASURING APPARATUS FOR PRESS |
摘要 |
PURPOSE:To improve the working efficiency of the titled device by searching the weight depending on a load voltage generated when a motor runs with an upper die mounted on a slide to measure the weight of the upper die accurately. CONSTITUTION:An upper die (not illustrated) is mounted on a side (not illustrated) and moved up and down with a slide motor 1. A current transformer 3 is mounted to one wire 2 in a circuit for energization of the slide motor 1 and a current converted to a voltage with an A/D converter 4 is inputted into a microcomputer 5. No-load voltage is memorized in a memory means 6 and then, it is substracted from a load voltage by a subtraction means 7 when the slide motor 1 runs with the upper die on. Thus, the weight is determined with a searching means 9 from the list 8 of weight for the voltage as predetermined. |
