Technical Field
[0001] This utility model relates to the field of welding technology for butt welding of low-carbon cold-rolled steel strips, and in particular to a welding device for butt welding of low-carbon cold-rolled steel strips. Background Technology
[0002] Steel strip refers to a conveyor belt made of carbon steel, used as the traction and carrying component of a belt conveyor, and also for bundling goods. It is a narrow and long steel plate produced by various steel rolling mills to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Steel strip, also known as strip steel, has a width of less than 1300mm, and its length varies slightly depending on the size of each coil. Steel strip is generally supplied in coils and has advantages such as high dimensional accuracy, good surface quality, ease of processing, and material saving. Steel strip is classified into two categories according to the material used: ordinary steel strip and high-quality steel strip. Steel strip is a steel product with large output, wide applications, and many varieties. According to processing methods, steel strips are classified into hot-rolled steel strips and cold-rolled steel strips; according to thickness, they are classified into thin steel strips (thickness not greater than 4mm) and thick steel strips (thickness greater than 4mm); according to width, they are classified into wide steel strips (width greater than 600mm) and narrow steel strips (width not greater than 600mm); narrow steel strips are further divided into directly rolled narrow steel strips and narrow steel strips slid from wide steel strips; according to surface condition, they are classified into original rolled surface and coated (plated) surface steel strips; according to application, they are classified into general-purpose and special-purpose steel strips.
[0003] Low-carbon cold-rolled steel strip is a type of steel strip that may break during use, requiring welding. Additionally, after the previous steel strip is coiled, it also needs to be butt-welded to meet production requirements. However, existing low-carbon cold-rolled steel strip welding equipment requires manual welding, which poses a significant risk, is not conducive to welding low-carbon cold-rolled steel strip, and has poor practicality.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 4A welding device for butt welding of low-carbon cold-rolled steel strip is shown, characterized in that it includes: a frame 1, support platforms 5 on the left and right sides of the frame 1, first support frames 2 on both the left and right sides of the frame 1, second support frames 3 symmetrically arranged in the middle of the frame 1, clamping conveyor rollers 4 on each of the first support frames 2, clamping butt joints 6 on each of the second support frames 3, fixed seats 7 fixed between the frame 1 and each of the second support frames 3, telescopic welding parts 8 on each of the fixed seats 7, drive mechanisms 100 symmetrically arranged on the rear side of the frame 1 to drive the clamping butt joints 6, moving mechanisms 200 arranged on the rear side of each fixed seat 7 to move the telescopic welding parts 8, and adjusting mechanisms 300 arranged above each of the first support frames 2 and the second support frames 3 to move the clamping conveyor rollers 4 and the clamping butt joints 6 respectively.
[0018] The above-described welding device for butt welding of low-carbon cold-rolled steel strip allows the user to transport the steel strip via the clamping conveyor roller 4 and support it on the support platform 5. Simultaneously, after the previous coil is wound up, its end is clamped by the clamping butt welding part 6. The next coil is then transported to the clamping butt welding part 6 via the clamping conveyor roller 4, which clamps it. The drive mechanism 100 then operates the clamping butt welding part 6, aligning the ends of the previous and next coils. At this point, the moving mechanism 200 moves the telescopic welding part 4, which welds the butt joint of the previous and next coils. The adjusting mechanism 300 adjusts the thickness of the clamping of the steel strip by the clamping conveyor roller 4 and the clamping butt welding part 6. Compared to existing technologies, this device can automatically butt weld steel strips and can accommodate steel strips of different thicknesses.
[0019] like Figure 3 As shown, in some embodiments of this utility model, the clamping and conveying roller section 4 includes first sliding grooves 41 arranged on the front and rear sides of each first support frame 2. A first movable frame 42 is movably inserted between each of the first sliding grooves 41 arranged on the front and rear sides. A transmission roller 43 is movably sleeved below each of the first support frames 2. A driven roller 44 is movably sleeved on each of the first movable frames 42. A first motor 45 is symmetrically fixed on the rear side of the frame 1. The sleeved end of each transmission roller 43 is fixedly connected to the output end of the adjacent first motor 45. After the steel strip is placed between the driven roller 44 and the transmission roller 43, the first motor 45 drives the transmission roller 43 to rotate, so that the transmission roller 43 cooperates with the driven roller 44 to clamp and convey the steel strip. When the adjusting mechanism 300 is operating, the first movable frame 42 moves and adjusts along the first sliding groove 41.
[0020] like Figure 3As shown, in some embodiments of this utility model, the clamping docking part 6 includes second sliding grooves 61 disposed on the front and rear sides of each second support frame 3, a second movable frame 62 is movably inserted between each of the front and rear second sliding grooves 61, an upper clamping roller 63 is movably sleeved on each of the second movable frames 62, a lower clamping roller 64 is movably sleeved below each of the second support frames 3, an extension shaft 65 extends from the sleeved end of each of the upper clamping rollers 63 and the lower clamping rollers 64, a sleeve groove 66 is provided on the rear side of each of the extension shafts 65, and a sleeve groove 66 is provided between every two adjacent sleeve grooves 66.

[0024] like Figure 4 As shown, in some embodiments of this utility model, the adjusting mechanism 300 includes a fourth threaded sleeve 301 fixed above each of the first movable frames 42 and the second movable frames 62. A shelf 302 is provided above each of the first support frames 2 and the second support frames 3. A fourth screw 303 that can be threadedly engaged with the fourth threaded sleeve 301 is movably sleeved on each shelf 302. A hexagonal nut 304 is fixed at the upper end of each fourth screw 303. When the user rotates the hexagonal nut 304, the hexagonal nut 304 drives the fourth screw 303 to rotate on the shelf 302. At this time, the fourth screw 303 drives the first movable frames 42 and the second movable frames 62 to move through the fourth threaded sleeve 301, thereby clamping the steel strip and adapting to the thickness of the steel strip.
