Die forging press stroke improved compensation method

Abstract

The invention discloses a die forging press stroke improved compensation method, and belongs to the technical field of die forging. The improved compensation method comprises the steps that S1, in thenormal field operation process of a die forging press, a somatosensory 3D binocular vision sensor module is used for collecting image video information of field operation of the die forging press inreal time; S2, a virtual three-dimensional environment of the die forging press and an operation site of the die forging press is reconstructed by utilizing a three-dimensional reconstruction module based on image processing; S3, in the virtual three-dimensional environment, a data processing module is used for collecting and processing data, a BP artificial neural network model is built, a corresponding compensation value is calculated, then a new travel deviation value is calculated and detected, and whether the travel deviation value meets the error range or not is judged; and S4, a displaymodule is used for displaying all the data. According to the improved compensation method, 3D modeling is utilized, the actual operation state of the die forging press is comprehensively and accurately reflected, die forging precision damage caused by inaccurate compensation values is effectively avoided, and manpower and material resource losses are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of die forging, in particular to a method for improving and compensating the stroke of a die forging press. Background technique [0002] In large-scale mechanical equipment and important equipment, such as steel rolling, power stations (hydropower, thermal power, nuclear power), petroleum, chemical industry, shipbuilding, aviation, aerospace, heavy weapons, etc., large free forgings and large die forgings are used. These large forgings are It is forged with a large free forging hydraulic press and a large die forging hydraulic press. Therefore, the production of large forgings has a very important position in advanced industrial countries, and even from the variety, quantity and grade of large free forging hydraulic presses and large die forging hydraulic presses owned by a country, its industrial level and national defense strength can be measured. [0003] For large-scale precision die forgings, such as ...

AI Technical Summary

Problems solved by technology

[0003]For large-scale precision die forgings, such as aviation die forgings, the overall development trend is large-scale, precision and integration, and the precision of forgings seriously affects the later use However, the size of the die forging press suitable for large die forgings is also very large, some of which can reach more than 30 meters. The deviation between the actual displacement and the expected displacement will lead to insufficient precision of die forgings and a significant increase in repair costs
