Description

TECHNICAL FIELD

[0001] The present application relates to the field of ore smelting furnace automation, and in particular to a steel drill bending deformation online correction device and method based on air cooling function. BACKGROUND

[0002] In the ore smelting furnace tapping operation process, the tapping robot plays a key role, and the hole drawing operation relies on the robot to drive the steel drill to repeatedly push and pull the hole. However, the front part of the steel drill is in contact with the material in the high-temperature material environment and is prone to thermal deformation, which seriously affects the subsequent operation accuracy of the steel drill, and further interferes with the overall quality and efficiency of the ore smelting furnace tapping operation.

[0003] The steel drill straightening mechanism equipped in the active tapping robot only corrects the steel drill through mechanical extrusion, lacks rapid cooling treatment after the steel drill is thermally deformed, and causes the steel drill to be in a high-temperature deformed state for a long time, which results in low straightening efficiency and is difficult to meet the demand of modern industry for high-efficiency production of ore smelting furnaces.

[0111] See Table 1 below for details:

[0112] Table 1

[0113]

[0114] Table 1 is an example of a coarse adjustment parameter database. According to experimental experience and requirements, those skilled in the art can have certain experience in controlling the coarse adjustment angle based on the steel bar model.

[0115] Coarse adjustment is a preset angle adjustment based on the steel drill model. The purpose is to achieve preliminary alignment of the air cooling module with the high temperature area of the steel drill through rapid positioning, and to lay a foundation for subsequent fine adjustment. The specific logic is as follows:

[0116] Trigger condition: When the steel drill is placed in the straightening channel formed by the upper and lower roller frames, the image recognition unit (industrial camera) matched with the furnace discharge robot automatically collects the shape image of the steel drill, identifies its key parameters such as diameter and length, and completes the steel drill model matching.

[0117] Parameter call: the control unit (embedded PLC) calls the pre-stored "coarse adjustment parameter database" according to the matched steel drill model, as shown in Table 1. The database calibrates the optimal initial angle range corresponding to different steel drill models through experiments, and the angle is based on the steel drill axis, ensuring that the nozzle spraying range covers the axial section where the steel drill high-temperature region is concentrated.

[0118] Execution adjustment: the control unit sends instructions to the drive unit (servo motor), and the servo motor output shaft drives the worm to rotate. The worm meshes with the worm gear to drive the entire air-cooled mounting plate to rotate. The adjustment process uses large step size to quickly approach the target range.

[0119] S3, adjust the nozzle in the steel drill straightening device to preliminarily align the axis of the steel drill, drive the air-cooled mounting plate to rotate through the worm drive assembly based on the initial angle adjustment range, and make the nozzle close to the high-temperature region coverage section;

[0120] S4, based on the temperature distribution image of the steel drill surface obtained by the infrared thermal imager, drive the worm drive assembly to make the nozzle align with the highest temperature point on the steel drill surface;

[0121] Steps S3 to S4 belong to fine angle adjustment, and fine adjustment is a dynamic compensation adjustment based on real-time image recognition, aiming to achieve complete alignment of the air-cooled module and the highest temperature region of the steel drill through accurate positioning, and improve cooling efficiency. The specific logic is as follows:

[0122] Trigger condition: after coarse adjustment is completed, the infrared thermal imager in the image recognition unit starts to collect the temperature distribution image of the steel drill surface, and focuses on identifying the high-temperature region with a temperature ≥ 300°C, especially the highest temperature point (usually the most severely deformed part).

[0123] Deviation calculation: the control unit processes the temperature image through fine adjustment algorithm: locates the coordinates of the highest temperature point (radial offset from the steel drill axis); calculates the angle deviation between the point and the current air-cooled module nozzle spraying center.

[0124] Execution adjustment: the control unit sends fine adjustment instructions to the servo motor according to the deviation value, and drives the worm-worm gear structure to rotate the air-cooled module in a small range. The adjustment uses small step size to gradually compensate, ensuring that the highest temperature point falls completely within the nozzle spraying range.

[0125] The specific fine adjustment algorithm in fine adjustment is prior art, which adjusts accurately in a small range after obtaining the offset value from the infrared thermal imager, to ensure that the highest point falls completely within the nozzle spraying range.

[0126] S5, adjust the flow and pressure in the air-cooled pipeline through the flow regulating valve, cool the highest temperature point on the steel drill surface through the nozzle, and repeat S3 until the highest temperature point on the steel drill surface is less than 200°.

[0127] The device is integrated online cooling and straightening: the high-temperature steel drill is cooled in real time through the air cooling module, the temperature of the steel drill is reduced, and the service life of the steel drill is prolonged. Quick replacement structure: the openable and closable structure design of the upper roller frame and the lower roller frame is matched with the wedge block connection mode, the quick replacement of the steel drill is realized, and the operation efficiency is improved. Multi-angle adjustable cooling system: the nozzle is adjusted at multiple angles through the elastic adjusting mechanism, the cooling angle can be adjusted according to the diameter and bending condition of the steel drill, and the uniform cooling effect is ensured. High-temperature and wear-resistant design: the high-temperature and wear-resistant layer on the surface of the straightening roller can withstand a temperature above 300 DEG C, the service life of the straightening roller is effectively improved, and the maintenance cost is reduced. Safety protection structure: the U-shaped setting (upper sealing top) of the upper roller frame effectively blocks the spatter and heat radiation in the furnace, and protects the safety of the equipment and the operating personnel. The present application aligns the highest temperature area through coarse adjustment angle and fine adjustment angle, and sequentially cools according to the temperature, so that deformation is prevented.
