The system comprises a plurality of detection sensors, a processing circuit, a computer, a magnetic railing ruler and a magnetic grid sensor, wherein the detection sensors are fixed to different positions of a hydraulic counter-blow hammer rack, and the processing circuit is used for analyzing and calculating filtering wave of detection signals of detection sensors, amplitude and frequency. The method comprises steps of processing signals output by detection sensors through vibration of a piezoelectric acceleration sensor detection rack, obtaining amplitude and frequency of the rack, and setting up a mathematical model between rack vibration and hammer blow energy through an experiment method so as to detect the blow energy. The mathematical model between the rack vibration and the hammer blow energy is set up through the experiment method, a piezoelectric acceleration sensor is installed on the counter-blow hammer rack, the blow energy is detected through an indirect method, the sensor is not required to be installed on the hammer head, and the loosening and the falling of the sensor caused by severe vibration during blowing are avoided.

Description

technical field [0001] The invention relates to a detection system and a detection method for the striking energy of a hydraulic die forging hammer, in particular to a large-scale hydraulic forging hammer energy detection system and a detection method. Background technique [0002] The rapid development of modern industry, especially in automobile, engineering, mining and other industries, requires more and more high-precision and high-quality die forgings. Die forgings have high productivity, high material utilization, and stable dimensions, especially for precision forgings. Due to the high precision after forging, cutting workload can be reduced or even eliminated. The proportion of die forgings to forgings represents the production level of a country's forging industry. [0003] The impact energy of the hydraulic pressure on the hammer directly affects the quality of the forging, and the hammer head impact speed detection technology is an important basis for realizing t...

AI Technical Summary

Problems solved by technology

Due to the high temperature of the forging, the vibration of the hammer head is severe when it hits, and the working environment on site is very harsh. It is difficult for conventional sensors to detect the hammer head hitting speed accurately and in real time.

And the sensor directly installed on the hammer head is easy to loosen and fall off during the striking process
