Giant stamp forging hydraulic press upright post stress harvester and stress monitoring system

Abstract

The invention discloses a giant die forging hydraulic press column stress acquisition device, which is characterized in that a sensor bracket is arranged on an upright column; a displacement sensor is arranged on the sensor bracket; one end of a displacement connecting rod is sleeved in a through hole of the sensor bracket and positioned below the displacement sensor; and the other end of the displacement connecting rod is fixedly arranged on the upright column. The invention also discloses a giant die forging hydraulic press column stress monitoring system, which comprises the giant die forging hydraulic press column stress acquisition device, an analog-to-digital converter and a microprocessor; and the industrial fieldbus technology is adopted to achieve fully digital communication of the detection system. By effectively monitoring the hydraulic press working column stress conditions in a real-time manner, the invention greatly improves the safety, reliability, application and maintenance efficiency, thus extending the service life of the giant die forging hydraulic press.

Description

technical field [0001] The invention belongs to the technical field of machinery and electronics, and relates to a stress collection device and a stress monitoring system for a column of a giant die forging hydraulic press. Background technique [0002] Large-scale die forging hydraulic press is an indispensable key equipment in aerospace, aviation, atomic energy, automobile, shipbuilding and other industries, and it is also an important equipment for heavy machinery manufacturing. It plays a key role in the technical level and productivity of a country's national defense industry and heavy machinery manufacturing, and is one of the important symbols of a country's industrialization level and economic and national defense strength. [0003] When the die forging hydraulic press is under the action of huge load, the contact nonlinearity of its complex structure, the gap between connection and kinematic pair and other factors produce singular load transmission and huge addition...

AI Technical Summary

Problems solved by technology

In the above methods, the sensor signals are all analog signals. Due to the harsh working environment of the giant die forging hydraulic press, long signal transmission lines, and poor anti-interference ability of analog signals, the collected signals are often inaccurate when using the above methods for detection, and the effect is not ideal. Difficult to play the role of monitoring and alarming the column stress of giant die forging hydraulic press
