Description

Technical Field

[0001] The present application relates to the technical field of welding detection, and in particular to a strip steel weld detection tensioning device for a galvanizing production line. Background Art

[0002] Galvanizing is a metal processing process that applies a thin coating of zinc to the base metal to protect the metal from corrosion.

[0003] Strip steel is a narrow and long steel plate. The width of the strip steel is generally between 20mm-200mm. The strip steel is generally thinner, and the thickness of the strip steel is generally between 1.8mm-6mm. When galvanizing the strip steel, in order to meet the continuous galvanizing requirements of the strip steel, the tail of the previous roll of strip steel and the head of the next roll of strip steel are generally welded by a welding machine.

[0004] After the welding of two rolls of steel strips is completed, in order to ensure that the welding quality meets the needs of continuous production, the quality of the weld between the two rolls of steel strips is generally tested. At present, when testing the welds of two rolls of steel strips, the weld of the steel strip is generally moved under the visual camera, and the visual camera is used to collect the weld photo information of the steel strip, and the collected weld photo information is transmitted to the detection software in the computer, so that the collected weld photo is compared with the qualified weld photo information in the detection software in the computer, so as to judge whether the weld of the steel strip is qualified.

[0005] Since the strip steel is relatively thin, it is easy for the strip steel to shake while moving. When taking pictures of the shaking strip steel weld with a visual camera, the pictures of the strip steel weld are likely to be unclear, which may lead to the possibility of misjudgment of the quality of the strip steel weld later. Utility Model Content

[0011] After the strip welding is completed, the strip is moved on the workbench, and the tensioning frame drives the lower pressure piece to move toward the direction close to the strip through the power unit. The strip is tightened by the cooperation between the lower pressure piece and the reference piece. When the strip weld moves below the visual camera, the strip weld is photographed by the visual camera.

[0029] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0030] An embodiment of the present application discloses a tensioning device for strip weld detection in a galvanizing production line.

[0031] A tensioning device for strip weld detection in a galvanizing production line includes a frame 1, a workbench 2, and a tensioning assembly 3.

The workbench 2 is installed on the frame 1, and the tensioning assembly 3 is installed at a position on the frame 1 close to the vision camera 11.

[0032] After the strip welding is completed, the strip is moved on the workbench 2. During the movement of the strip, the strip is tensioned by the tensioning assembly 3 to reduce the possibility of the strip shaking during the movement on the workbench 2. When the weld of the strip passes by the vision camera 11, the vision camera 11 photographs the weld of the strip and transmits the weld photo to the computer. The current strip weld photo is compared with the qualified weld photo through the detection software inside the computer to determine whether the current strip weld is qualified.

[0033] A placement groove 21 is formed at the top of the workbench 2 along the strip movement direction, and the placement groove 21 penetrates through both ends of the top of the workbench 2. A plurality of groups of tensioning grooves 211 are formed on the vertical inner wall of the placement groove 21 along the length direction of the workbench 2. Each group of tensioning grooves 211 includes two tensioning grooves 211, and the two tensioning grooves 211 are respectively arranged on two opposite vertical inner walls of the placement groove 21.

[0036] The tensioning frame 31 includes a vertical plate 311, an upper cross plate 312, and a lower cross plate 313. A sliding groove 12 is formed at the top of the frame 1, and the sliding groove 12 penetrates through the bottom of the frame 1. The vertical plate 311 is slidably installed inside the sliding groove 12, and the vertical plate 311 is guided and limited by the inner wall of the sliding groove 12. The upper cross plate 312 is fixedly installed at the top of the vertical plate 311, and the lower cross plate 313 is fixedly installed at the bottom of the vertical plate 311. The entire tensioning frame 31 is arranged in a C-shaped structure, and the upper cross plate 312 and the lower cross plate 313 clamp the frame 1.

[0037] The power unit 33 is an electric telescopic rod, one end of which is fixedly mounted on the bottom of the frame 1, and the other end of which is fixedly connected to the top of the lower cross plate 313. The relative position of the tensioning frame 31 and the frame 1 is adjusted by changing the overall length of the electric telescopic rod.

[0038] The adjusting part 32 includes a reference member 321 and a pressing member 322. There are a plurality of reference members 321, and the plurality of reference members 321 correspond to a plurality of groups of tensioning grooves 211 one by one. The reference member 321 includes a guide rod 3211, a reference frame 3213, a spring 3212 and a reference roller 3214. The guide rod 3211 is located inside the tensioning groove 211, one end of the guide rod 3211 is fixed to the inner wall at the bottom of the tensioning groove 211, and the other end of the guide rod 3211 contacts the bottom of the blocking block 212.

[0039] The two ends of the reference frame 3213 correspond to the two tensioning grooves 211 of the same group, and the two ends of the reference frame 3213 are provided with guide holes, the guide rod 3211 and the corresponding guide holes are slidably matched, the reference roller 3214 is rotatably mounted on the reference frame 3213, and the bottom of the strip steel and the top of the reference roller 3214 are rollingly matched. The spring 3212 is sleeved on the outer periphery of the guide rod 3211, and one end of the spring 3212 contacts the bottom of the tensioning groove 211, and the other end of the spring 3212 contacts the bottom of the reference frame 3213.

[0040] The lower pressing member 322 includes a lower pressing frame 3221 and a lower pressing roller 3222.

[0041] The implementation principle of the strip steel weld inspection and tensioning device of the galvanized production line in the embodiment of the present application is as follows: after the strip steel welding is completed, the strip steel is moved from the feed end of the workbench 2 to the discharge end of the workbench 2, and the strip steel is guided by the rotating rollers 22 at both ends of the workbench 2 to reduce the moving resistance of the strip steel. When the strip steel moves on the workbench 2, the electric telescopic rod is gradually extended as a whole, so that the tensioning frame 31 is pressed downward as a whole. When the tensioning frame 31 moves downward, the strip steel is pressed on the reference roller 3214 by the lower pressure roller 3222. The lower pressure roller 3222 and the reference roller 3214 cooperate with each other to tighten the strip steel, reducing the possibility of the strip steel shaking. When the strip steel weld moves below the visual camera 11, the strip steel weld is photographed by the visual camera 11, and the photographed strip steel weld photo is transmitted to the detection software in the computer. The detection software in the computer compares the current strip steel weld photo with the qualified weld photo in the detection software in the computer to determine whether the current strip steel weld is qualified. When the strip is tightened, the reference roller 3214 is subjected to force to make the reference frame 3213 slide on the guide rod 3211 and compress the spring 3212, thereby reducing the possibility of the strip being damaged due to excessive force. At the same time, the blocking block 212 limits the reference frame 3213, reducing the possibility of the reference frame 3213 sliding out of the tensioning groove 211 under the elastic force of the spring 3212.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
