Description

Technical Field

[0001] The invention relates to an online maintenance device for cold rolling mill welding machine equipment, in particular to a guide wheel grinding device for a cold rolling strip steel welding machine. Background Art

[0002] At present, in a steel company's cold rolling and acid rolling unit, a high-power laser welder is used to weld the cold-rolled strip steel, welding the tail of the front steel coil with the head of the rear steel coil, thereby realizing the unit's fully continuous high-speed rolling production.

[0003] A guide wheel device is provided at the laser welding machine. There are two guide wheels in the guide wheel device. The two guide wheels are arranged at a certain angle. When the laser welding machine welds the cold-rolled strip, the guide wheels of the guide wheel device clamp the cold-rolled strip to correct and control the strip shape at the laser welding position. Since a large amount of welding slag will splash out during the welding process, and the position where the guide wheel is welded to the strip is relatively close, some of the splashed welding slag will splash and adhere to the edge of the guide wheel. When there is too much welding slag adhered to the edge of the guide wheel, the welding slag must be cleaned, otherwise it will affect the effect of the guide wheel in controlling the strip shape. At present, the cleaning of welding slag at the edge of the guide wheel is mainly implemented manually. Specifically, the guide wheel device needs to be shut down first, and then the operator arrives at the site and uses tools such as files and handheld grinders to clean the welding slag at the edge of the guide wheel. The manual cleaning method has low work efficiency and high labor intensity, and the guide wheel device must be shut down first, which seriously affects the continuity of production operation.

[0004] Chinese patent CN202110625516.5 discloses a cold-rolled stainless steel strip high-efficiency cleaning device and cleaning method thereof, which sets a guide wheel, a tee, a branch pipe and a nozzle, makes the stainless steel strip perpendicular to the equipment surface through the guide wheel, and sends the cleaning liquid to the nozzle through the branch pipes of the equipment on the left and right sides of the tee, and cleans the steel strip through the nozzle, so that the upper and lower sides of the stainless steel strip can be cleaned at the same time, thereby improving the cleaning efficiency of the equipment. However, the device and method are aimed at high-pressure cleaning of stainless steel strips, and do not involve the technical solution of online grinding and slag removal. Summary of the invention

[0037] The camera 21 is electrically connected to the main control unit through a signal wire, and the main control unit can obtain image signals at the edges of the two guide wheels 11 of the guide wheel device 1 from the camera 21. The first grinding machine 31, the first telescopic drive cylinder 32, the second grinding machine 41, the second telescopic drive cylinder 43, the vacuum cleaner 51, the third telescopic drive cylinder 55 and the fourth telescopic drive cylinder 56 are all controlled and connected to the main control unit through control signal wires. A control program is set in the main control unit, which receives the image signal of the camera 21 and controls the first grinding machine 31, the first telescopic drive cylinder 32, the second grinding machine 41, the second telescopic drive cylinder 43, the vacuum cleaner 51, the third telescopic drive cylinder 55 and the fourth telescopic drive cylinder 56 to work in coordination.

[0038] See also Figure 5The specific control process of the control program is as follows: when the guide wheel device 1 is in a normal working state, the first telescopic drive cylinder 32 of the first grinding assembly 3 and the second telescopic drive cylinder 43 of the second grinding assembly 4 are both in a retracted state, the grinding heads of the first grinding machine 31 and the second grinding machine 41 are both separated from the guide wheel 11 of the guide wheel device 1, and the camera 21 of the image acquisition assembly 2 continuously transmits the images of the edges of the two guide wheels 11 to the main control unit, and the main control unit continuously analyzes the images of the edges of the guide wheels 11 to determine whether there is welding slag adhesion at the edges of the guide wheels 11. When it is determined that the edges of the guide wheels 11 are When the welding slag adhesion reaches a certain degree (considered to be relatively serious), the main control unit controls the first telescopic drive cylinder 32 and the second telescopic drive cylinder 43 to respectively drive the first grinding machine 31 and the second grinding machine 41 to move and start the first grinding machine 31 and the second grinding machine 41 to start operation, and the grinding heads of the first grinding machine 31 and the second grinding machine 41 lean against the guide wheel 11 for grinding, so as to clean the welding slag at the edge of the guide wheel 11. After the grinding is completed, the main control unit controls the first telescopic drive cylinder 32 and the second telescopic drive cylinder 43 to respectively drive the first grinding machine 31 and the second grinding machine 41 to separate from the guide wheel 11. The grinding of the guide wheel 11 can be selected to be performed in the stop interval of the guide wheel device 1. Specifically, when the control program in the main control unit determines that the welding slag adhesion is relatively serious, it is determined whether the guide wheel device 1 is still in a normal production working state. If so, it waits, and when the guide wheel device 1 is in a stop state, the guide wheel 11 is started to be ground. Since the guide wheel grinding device does not need to be stopped when grinding the guide wheel device, such grinding can be considered as online grinding. In addition, before the first grinding machine 31 and the second grinding machine 41 grind the guide wheel 11, the main control unit also controls the third telescopic drive cylinder 55 and the fourth telescopic drive cylinder 56 in the dust collection assembly 5 to respectively drive the first telescopic dust collection tube 53 and the second telescopic dust collection tube 54 to extend, the first dust collection hood 57 moves to the top of the first grinding machine 31, and the second dust collection hood 58 moves to the bottom of the second grinding machine 41. When grinding the guide wheel 11, the dust collection machine 51 is controlled to start running, and the dust collection machine 51 can cleanly remove the smoke and debris generated when grinding the guide wheel 11 to prevent the surface quality of the welded cold-rolled steel strip and the quality of the weld from being affected.

[0039] It should be noted that the analysis method adopted by the main control unit to analyze the image of the edge of the guide wheel 11 is the "height difference analysis method". Specifically, the main control unit compares the height of the currently taken guide wheel edge image with the previously taken new guide wheel edge image. When the height difference between the two exceeds the set value, it is determined that the welding slag adhesion of the guide wheel edge is already serious, and the main control unit controls the guide wheel grinding device to grind the guide wheel edge.

[0040] The guide wheel grinding device of the present embodiment has the advantages that: in the guide wheel grinding device, the first grinding component 3 and the second grinding component 4 for grinding the guide wheel 11 are arranged on the side of the guide wheel 11, and an image acquisition component 2 is arranged at the edge of the guide wheel 11 to detect the welding slag adhesion at the edge of the guide wheel 11. When the main control unit detects that the welding slag adhesion is relatively serious through the image acquisition component 2, the control program in the main control unit automatically controls the first grinding component 3 and the second grinding component 4 to grind the guide wheel 11, thereby facilitating the rapid online grinding of the guide wheel 11 during the stop interval of the guide wheel device 1. In this way, compared with the original manual grinding of the guide wheel 11, the working efficiency of grinding the guide wheel 11 is greatly improved, thereby effectively ensuring the continuity of the production operation of the guide wheel device 1, and also reducing the labor load of the operators.

[0041] In the present embodiment, the first telescopic drive cylinder 32, the second telescopic drive cylinder 43, the third telescopic drive cylinder 55 and the fourth telescopic drive cylinder 56 are all pneumatic telescopic cylinders, while in other embodiments, electric telescopic cylinders may also be used.

[0042] In this embodiment, the first grinder 31 and the second grinder 41 can be understood as grinding machines, and the grinding heads thereof are grinding wheels.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
