Title:
HYDRAULIC PROTECTION PRESSURE DETECTING SYSTEM AND METHOD FOR PROTECTING FINE TUNING MECHANISM OF PRESS
Document Type and Number:
WIPO Patent Application WO/2010/072160
Kind Code:
A1
Abstract:
A hydraulic protection pressure detecting system for protecting the fine tuning mechanism of a press comprises a pressure transducer (2) for dynamically measuring the hydraulic protection pressure and transmitting the measured data to an analog-digital (AD) module (5) of a PLC. The AD module (5) processes the measured data. The system further comprises a relay (4) for performing the press-driven enabling of the press when the pressure processed by the AD module (5) is normal, system pressure error verification means (7) for determining if said pressure is too high and interrupting the press-driven enabling of the fine tuning mechanism if said pressure is too high, and a human-machine interface (HMI) for displaying the pressure data of the AD module (5) and the alarming of ERROR as well as the condition of the press-driven enabling. A hydraulic protection pressure detecting method for protecting a fine tuning mechanism of a press is also disclosed. The system and the method can ensure the normal operation of the fine tuning mechanism of a press and reduce cost.
