Cubic press health monitoring method and system

Abstract

The invention proposes a cubic press health monitoring method and system. The monitoring system comprises a power management module, a signal processing module and a remote control monitoring module which are serially connected. The signal processing module comprises a strain detection module, a signal conditioning module, a microprocessor, a storage module and a wireless data transmission module; the strain detection module comprises a strain collection sheet, a bridge-type compensation circuit, and an electronic switch; the signal conditioning module comprises a passage amplifier, a filter and an A / D converter; The remote control monitoring module is arranged in a remote monitoring room and acquires the test data through the wireless data transmission module. The aim of online health monitoring of cubic presses is achieved based on an electrical strain measuring method and modern wireless transmission technology. The cubic press health monitoring system can accurately acquire weak strain signal data, has the functions of online monitoring and real-time display and recording of equipment usage status, and can predicate the fatigue life of equipment in actual work conditions, thereby preventing great and malignant accidents and reducing losses.

Description

Technical field: [0001] The invention relates to the field of six-sided hydraulic press monitoring, in particular to a health monitoring method and system for a six-sided hydraulic press. Background technique: [0002] The six-sided top hydraulic press is an ultra-high-pressure equipment for synthesizing superhard materials and their products. It is mainly used in the manufacture of synthetic diamond, single crystal and polycrystalline cubic boron nitride, and synthetic polycrystalline diamond, polycrystalline cubic boron nitride composite sheets, etc. Processing and production in the field of superhard materials, the working pressure is up to 100MPa. During the working process of the hydraulic press, the impact caused by the reversing and pressure relief of the hydraulic drive parts (piston, plunger) affects the normal operation of the equipment. Such a long time and regular reciprocating cycle of load can easily make the six-sided hydraulic press Fatigue damage at stress ...

Problems solved by technology

During the working process of the hydraulic press, the impact caused by the reversing and pressure relief of the hydraulic drive parts (piston, plunger) affects the normal operation of the equipment. Such a long time and regular reciprocating cycle of load can easily make the six-sided hydraulic press Fatigue damage at stress concentration points (such as hinge beams, working cylinders, key stress-bearing points of lifting lugs) will cause cracks in severe cases, and even directly cause equipment failure, resulting in personal casualties and economic losses
