Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and in particular relates to a steel strip butt welding machine. Background Technology

[0002] A steel strip welding machine is a device used for welding steel strips. It is commonly used in the production process of metal products such as steel strips, steel pipes, and steel wires. It melts or shapes the contact surfaces of two steel strips through heating and pressure to form a strong welded joint.

[0003] If the two steel strips are not aligned during the welding process, the welded joint may be uneven, offset or misaligned, resulting in poor welding quality and failing to ensure the continuity and stability of production. Therefore, we have proposed a steel strip butt welding machine. Utility Model Content

[0004] The purpose of this utility model is to provide a steel strip welding machine, in which the rotation of the threaded rod causes the pressure plate to move downward, pressing and fixing the steel strip. Then, the rotation of the threaded rod will drive the moving bar to move, thereby bringing the two steel strips closer together and making them flush, thus solving the problem of automatic alignment of the steel strips.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a steel strip welding machine, including a box body, a welding machine fixedly connected to the top of the box body, an alignment mechanism provided on the box body, and a fixing mechanism provided on the box body;

[0007] The alignment mechanism includes a limiting block 1, a threaded rod rotatably connected to the inner wall of the limiting block 1, a bolt threadedly connected to the inner wall of the threaded rod 1, a moving strip threadedly connected to the outer surface of the threaded rod 1, a connecting frame 1 fixedly connected to the outer surface of the moving strip, a sliding groove 1 inside the connecting frame 1, a moving block 1 slidably connected to the inner wall of the sliding groove 1, a threaded rod 2 threadedly connected to the inner wall of the moving block 1, an extension plate rotatably connected to the outer surface of the threaded rod 2, a fixing rod 1 slidably connected to the inner wall of the moving block 1, a limiting block 2 fixedly connected to the outer surface of the box, and a pressure plate 1 fixedly connected to the outer surface of the moving block 1.

[0008] Furthermore, the outer surface of the limiting block is fixedly connected to the outer surface of the box, the outer surface of the bolt is in contact with the outer surface of the limiting block, two sliding grooves are provided, and the outer surface of the extension plate is fixedly connected to the outer surface of the connecting frame.

[0009] Furthermore, the bottom of the fixing rod is fixedly connected to the top of the extension plate, the inner wall of the limiting block is rotatably connected to the outer surface of the threaded rod, and the outer surface of the pressure plate is slidably connected to the inner wall of the connecting frame.

[0010] Furthermore, the fixing mechanism includes a connecting frame two fixedly connected to the outer surface of the box body, and a sliding groove two is provided inside the connecting frame two. There are two sliding grooves two in total, and a moving block two is slidably connected to the inner wall of the sliding groove two.

[0011] Furthermore, a pressure plate is fixedly connected to one side of the two movable blocks that are close to each other, a threaded rod is threadedly connected to the inner wall of the two movable blocks, an extension plate is rotatably connected to the outer surface of the threaded rod, and the outer surface of the extension plate is fixedly connected to the outer surface of the connecting frame.

[0012] Furthermore, a fixing rod 2 is slidably connected to the inner wall of the movable block 2, the bottom of the fixing rod 2 is fixedly connected to the top of the extension plate 2, a placement frame is fixedly connected to the top of the box, and a clamping strip is slidably connected to the inner wall of the placement frame, with a total of two clamping strips.

[0013] Furthermore, a connecting strip is fixedly connected to the side of the clamping strip away from the placement frame, and a sliding rod is fixedly connected to the side of the connecting strip away from the clamping strip. There are two sliding rods in total, and a limiting strip is slidably connected to the outer surface of the sliding rod. The bottom of the limiting strip is fixedly connected to the top of the box.

[0014] Furthermore, a spring is fixedly connected to the side of the limiting strip near the clamping strip. Several springs are provided in total. The end of the spring away from the limiting strip is fixedly connected to the outer surface of the connecting strip. The inner side of the spring is sleeved with the outer surface of the sliding rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a movable strip that rotates the threaded rod 2, causing the threaded rod 2 to move the movable block 1 downwards. At this time, the movable block 1 moves the pressure plate 1 downwards, and then the pressure plate 1 presses and fixes the steel strip on the other side. Finally, the threaded rod 1 is rotated again, causing the movable strip to move towards the steel strip on the other side. By using a movable strip that can move along the threaded rod 1, the steel strip can be automatically aligned, ensuring that both ends of the steel strip are parallel. This reduces joint errors and welding defects during the welding process, and ensures the continuity and stability of production.

[0017] 2. This utility model, by setting up a pressure plate two, allows the connecting bar to push the clamping bar, so that the clamping bar initially positions the steel strip. Then, the threaded rod three rotates, at which time the threaded rod three causes the moving block two to move downward. Then, the moving block two drives the pressure plate two to move downward, so that the pressure plate two presses and fixes the steel strip. By using the pressure plate two, which can slide within the connecting frame two, the steel strip can be fixed during welding. This ensures that the two steel strips always maintain the correct docking position during the welding process, avoiding uneven welding, weakened joints, or even welding defects.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 As shown, this utility model is a steel strip welding machine, including a box 101, a welding machine 102 fixedly connected to the top of the box 101, an alignment mechanism 2 provided on the box 101, and a fixing mechanism 3 provided on the box 101.

[0030] The alignment mechanism 2 includes a limiting block 201. First, the fixing mechanism 3 positions and fixes the two steel strips, and then the alignment mechanism 2 aligns the two steel strips, facilitating subsequent welding. A threaded rod 202 is rotatably connected to the inner wall of the limiting block 201. A bolt 203 is threadedly connected to the inner wall of the threaded rod 202. A movable strip 204 is threadedly connected to the outer surface of the threaded rod 202. A connecting frame 205 is fixedly connected to the outer surface of the movable strip 204, allowing the threaded rod 202 to rotate. This rotation causes the movable strip 204 to move within the box. The body 101 slides within the frame, causing the moving strip 204 to move and align the steel strip. A groove 206 is provided inside the connecting frame 205. A moving block 207 is slidably connected to the inner wall of the groove 206. A threaded rod 209 is threadedly connected to the inner wall of the moving block 207. An extension plate 208 is rotatably connected to the outer surface of the threaded rod 209. The groove 206 restricts the movement of the moving block 207, preventing it from rotating due to movement, thus ensuring stable clamping and fixing of the steel strip. A fixing plate 208 is slidably connected to the inner wall of the moving block 207. Rod 210 is fixedly connected to the outer surface of housing 101, and a pressure plate 212 is fixedly connected to the outer surface of moving block 207. The outer surface of the limiting block 201 is fixedly connected to the outer surface of housing 101. The fixing rod 210 makes the movement of moving block 207 on the other side more stable, thereby ensuring that the pressure plate 212 can move stably and press and fix the steel strip. The outer surface of bolt 203 contacts the outer surface of the limiting block 201. Two slide grooves 206 are provided. The outer surface of extension plate 208 is fixedly connected to the outer surface of connecting frame 205. Bolt 203 can fix the threaded rod 202 after rotation, preventing the threaded rod 202 from rotating during alignment and affecting the normal operation of the device. The bottom of the fixing rod 210 is fixedly connected to the top of the extension plate 208. The inner wall of the limiting block 211 is rotatably connected to the outer surface of the threaded rod 202. The outer surface of the pressure plate 212 is slidably connected to the inner wall of the connecting frame 205. The limiting block 211 fixes the position of the threaded rod 202, preventing the threaded rod 202 from detaching from the device during rotation and affecting the normal operation of the device.

[0031] The fixing mechanism 3 includes a connecting frame 301 fixedly connected to the outer surface of the housing 101. The connecting frame 301 has two sliding grooves 302 inside. A movable block 303 is slidably connected to the inner wall of each sliding groove 302. The sliding groove 302 restricts the movement of the movable block 303, preventing it from rotating during movement and ensuring the normal operation of the device. A pressure plate 304 is fixedly connected to one side of the movable blocks 303 that is close to each other. A threaded rod 305 is threadedly connected to the inner wall of the movable blocks 303. An extension plate 306 is rotatably connected to the outer surface of the threaded rod 305. The outer surface of the extension plate 306 is fixedly connected to the outer surface of the connecting frame 301, allowing for the adjustment of the threaded rod. When the threaded rod 305 rotates, the moving block 303 moves downward, which in turn causes the pressure plate 304 to move downward to clamp the steel strip. The inner wall of the moving block 303 is slidably connected to the fixing rod 307. The bottom of the fixing rod 307 is fixedly connected to the top of the extension plate 306. The top of the box 101 is fixedly connected to the placement frame 308. The inner wall of the placement frame 308 is slidably connected to the clamping strip 309. There are two clamping strips 309. The fixing rod 307 positions the movement of the pressure plate 304, so that the pressure plate 304 can only move along a specific track, preventing the pressure plate 304 from deviating and ensuring that the pressure plate 304 can stably clamp the steel strip.

[0032] A connecting strip 310 is fixedly connected to the side of the clamping strip 309 away from the placement frame 308. A sliding rod 311 is fixedly connected to the side of the connecting strip 310 away from the clamping strip 309. There are two sliding rods 311. A limit strip 312 is slidably connected to the outer surface of the sliding rod 311. The sliding rod 311 can make the clamping strip 309 move along a specific track to prevent the clamping strip 309 from deviating, so as to accurately position the steel strip. The bottom of the limit strip 312 is fixedly connected to the top of the box 101. A spring 313 is fixedly connected to the side of the limit strip 312 near the clamping strip 309. There are several springs 313. The end of the spring 313 away from the limit strip 312 is fixedly connected to the outer surface of the connecting strip 310. The inner side of the spring 313 is sleeved with the outer surface of the sliding rod 311. During the compression or rebound of the spring 313, the sliding rod 311 prevents the spring 313 from deviating, so that the clamping strip 309 can stably contact the steel strip to position the steel strip.

[0033] One specific application of this embodiment is:

[0034] When the equipment is needed, the two steel strips are first placed in the placement frame 308, positioning them between the two clamping bars 309. The spring 313 then rebounds, pushing the connecting bar 310 towards each other. This causes the connecting bar 310 to slide the sliding rod 311 within the limiting bar 312. The connecting bar 310 then pushes the clamping bars 309, initially positioning the steel strip. Next, the threaded rod 305 rotates, causing the moving block 303 to move downwards. The moving block 303 then moves the pressure plate 304 downwards, pressing and fixing the steel strip. This secures the steel strip during welding, ensuring the two steel strips maintain the correct alignment during welding and preventing uneven welding. The process weakens the weld head and even causes welding defects. Then, the threaded rod 209 is rotated, causing the moving block 207 to move downwards. At this time, the moving block 207 will move the pressure plate 212 downwards, and the pressure plate 212 will press and fix the steel strip on the other side. Finally, the threaded rod 202 is rotated, causing the moving bar 204 to move towards the steel strip on the other side, so that the two steel strips come into contact with each other. When the two steel strips are aligned, the bolt 203 is tightened inside the threaded rod 202 to fix the position of the threaded rod 202. This achieves the effect of automatically aligning the steel strips, ensuring that the two ends of the steel strips are parallel, reducing joint errors and welding defects during the welding process, and ensuring the continuity and stability of production. Then, the two steel strips can be welded by the welding machine 102.
