Description

Technical Field

[0001] This utility model belongs to the technical field of welding wire processing equipment, and in particular relates to a wear-resistant welding wire multi-roller progressive straightening machine. Background Technology

[0002] Wear-resistant welding wire is used as filler metal in the welding process to form welds with high wear resistance. Solid wear-resistant welding wire is mainly made of various alloy steels and contains a variety of alloying elements, such as chromium, molybdenum, tungsten, vanadium, niobium, and boron. The different proportions of these alloying elements determine the wear resistance and other properties of the welding wire. Flux-cored wear-resistant welding wire, on the other hand, is made by rolling thin steel strips into round or shaped steel tubes, filling them with a certain composition of flux powder, and then drawing them.

[0003] With the continuous development of the manufacturing industry and technological progress, the requirements for the quality and performance of welding materials are becoming increasingly stringent. Using advanced multi-roller progressive straightening machines to process wear-resistant welding wire is a necessary measure that conforms to the industry development trend and helps to promote the development and application of welding technology. At the same time, wear-resistant welding wire manufacturers also need to effectively straighten the welding wire in order to improve product quality and market competitiveness.

[0004] Existing equipment is not convenient for adjusting the height of the rollers. When processing welding wires of different diameters, it is often necessary to replace the rollers with suitable ones before subsequent processing can be carried out, which is very inconvenient and also reduces the versatility and flexibility of the device. Therefore, we propose a wear-resistant welding wire multi-roller progressive straightening machine. Utility Model Content

[0005] The purpose of this utility model is to provide a wear-resistant welding wire multi-roller progressive straightening machine. Through the adjustment mechanism and cleaning mechanism, it solves the problem that the existing equipment is not convenient to adjust the height of the rollers during use. When it is necessary to process welding wires of different diameters, it is often necessary to replace the appropriate rollers before subsequent processing can be carried out, which is very inconvenient and also reduces the versatility and flexibility of the device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a wear-resistant welding wire multi-roller progressive straightening machine, including a mounting base, a roller is fixedly connected to the top outer wall of the mounting base, a protective cover is fixedly connected to the outer wall of the roller, and an adjustment mechanism is provided on the outer wall of the mounting base.

[0008] The adjusting mechanism includes several sliding rod sleeves, the outer walls of which are fixedly connected to the top outer wall of the protective cover. Each sliding rod sleeve has a limiting groove on its inner wall. A rotating rod is rotatably connected to the inner wall of each sliding rod sleeve, and a lifting rod is rotatably connected to the inner wall of each rotating rod. The outer wall of the lifting rod is slidably connected to the inner wall of the limiting groove. A worm gear is rotatably connected to the inner wall of the protective cover near the worm gear. A first motor is fixedly connected to the inner wall of the protective cover near the worm gear. The bottom output end of the first motor is fixedly connected to the outer wall of the worm gear. A worm wheel is fixedly connected to the outer wall of each rotating rod near the worm gear, and the outer wall of the worm wheel meshes with the outer wall of the first motor.

[0009] Furthermore, a top plate is fixedly connected to the top outer wall of the lifting rod, and a number of threaded rods are rotatably connected to the inner wall of the top plate, with threaded rod sleeves threadedly connected to the outer walls of the threaded rods.

[0010] Furthermore, the outer wall of the threaded rod sleeve is slidably connected to the inner wall of the top plate, and rollers are fixedly connected to the bottom outer walls of several threaded rod sleeves. A cleaning mechanism is provided on the outer wall of the mounting base.

[0011] Furthermore, the cleaning mechanism includes a second motor, the outer wall of the second motor is fixedly connected to the outer wall of the mounting base, the bottom output end of the second motor is fixedly connected to a drive shaft via a coupling, and several fixing plates are fixedly connected to the top outer wall of the mounting base near the drive shaft.

[0012] Furthermore, the inner walls of several fixed plates are rotatably connected to rotating shafts, and the outer walls of several rotating shafts are fixedly connected to pulleys on the outer walls of the transmission shafts.

[0013] Furthermore, a belt is connected to the outer wall of the pulley, and a turntable is fixedly connected to the outer wall of the end of the rotating shaft away from the pulley.

[0014] Furthermore, a limiting shaft is fixedly connected to the outer wall of the turntable, and a connecting rod is rotatably connected to the outer wall of the limiting shaft.

[0015] Furthermore, a plurality of brush plates are slidably connected to the inner wall of the mounting base near the connecting rod, and a limiting shaft two is fixedly connected to the outer wall of the brush plates. The outer wall of the limiting shaft two is rotatably connected to the inner wall of the connecting rod.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a worm gear on a rotating rod. When the equipment is in use, the welding wire passes through rollers and roller 2 from the end furthest from the brush plate and exits from the end closest to the brush plate. During the wire feeding process, the wire continuously passes through rollers and roller 2, eventually being straightened. When it is necessary to control the diameter of the straightened welding wire, the first motor is started. The rotation of the first motor drives the worm gear to rotate, causing multiple worm gears to rotate simultaneously. The rotation of the worm gears drives the rotating rod to rotate, allowing the height of the rollers to be adjusted. This makes the straightening machine suitable for welding wires of different diameters without the need to change equipment or make complex adjustments. Simply adjusting the roller height can meet the straightening requirements of different production tasks for welding wires of different specifications, improving the versatility and flexibility of the equipment.

[0018] 2. This utility model incorporates a limiting shaft on the turntable. When the equipment is in use, starting the second motor causes the transmission shaft to rotate, simultaneously rotating multiple pulleys at the lower end. The rotation of the lower pulleys causes the belt to rotate, which in turn causes the upper pulley to rotate, thereby rotating the rotating shaft. The rotation of the rotating shaft causes the turntable to rotate, and the limiting shaft performs an eccentric circular motion around the rotating shaft, which in turn drives the connecting rod to move. This allows for the cleaning of the straightened welding wire, removing impurities such as oil and metal shavings that may have accumulated due to contact with rollers and other components, or contaminants such as rust and dust that may have been present on the surface of the welding wire, thus ensuring the reliability of the welded structure.

[0019] 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

[0029] 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.

[0030] Please see Figure 1-6 As shown, this utility model is a wear-resistant welding wire multi-roller progressive straightening machine, including a mounting base 1. A roller 101 is fixedly connected to the top outer wall of the mounting base 1. A protective cover 102 is fixedly connected to the outer wall of the roller 101. An adjustment mechanism 2 is provided on the outer wall of the mounting base 1. The protective cover 102 can protect the first motor 207 and prevent the first motor 207 from being damaged by external forces.

[0031] The adjusting mechanism 2 includes several sliding rod sleeves 201. The outer walls of each sliding rod sleeve 201 are fixedly connected to the top outer wall of the protective cover 102. Each sliding rod sleeve 201 has a limiting groove 202 on its inner wall. A rotating rod 203 is rotatably connected to the inner wall of each sliding rod sleeve 201. When the rotating rod 203 moves, it drives the lifting rod 204 to rise or fall along the arc-shaped sliding groove of the rotating rod 203, thereby changing the height of the top plate 208. The lifting rod 204 is rotatably connected to the inner wall of the rotating rod 203. The outer wall of the lifting rod 204 is slidably connected to the inner wall of the limiting groove 202. A worm gear 206 is rotatably connected to the inner wall of the protective cover 102. A first motor 207 is fixedly connected to the inner wall of the end of the protective cover 102 near the worm 206. When the first motor 207 is started, the rotation of the first motor 207 will drive the worm 206 to rotate, which in turn will cause the worm wheel 205 to rotate. The rotation of the worm wheel 205 will drive the rotating rod 203 to rotate. The bottom output end of the first motor 207 is fixedly connected to the outer wall of the worm 206. The outer wall of the rotating rod 203 near the worm 206 is fixedly connected to the worm wheel 205. The outer wall of the worm wheel 205 meshes with the outer wall of the first motor 207. Since the worm wheel 205 and the worm 206 mesh with each other, the rotation of the worm 206 can drive the worm wheel 205 to rotate.

[0032] A top plate 208 is fixedly connected to the top outer wall of the lifting rod 204. Several threaded rods 209 are rotatably connected to the inner wall of the top plate 208. Threaded rod sleeves 210 are threadedly connected to the outer walls of each threaded rod 209. The outer walls of the threaded rod sleeves 210 are slidably connected to the inner wall of the top plate 208. Rollers 211 are fixedly connected to the bottom outer walls of each threaded rod sleeve 210. By adjusting the rollers 211 at different positions, the diameter of the straightened welding wire can be freely controlled. (Mounting base) The outer wall of the mounting base 1 is provided with a cleaning mechanism 3, which includes a second motor 301. The outer wall of the second motor 301 is fixedly connected to the outer wall of the mounting base 1. The bottom output end of the second motor 301 is fixedly connected to a transmission shaft 302 through a coupling. Several fixing plates 303 are fixedly connected to the top outer wall of the mounting base 1 near the transmission shaft 302. The fixing plates 303 can limit the position of the rotating shaft 304 to prevent the rotating shaft 304 from falling off, and at the same time, they can make the rotating shaft 304 rotate only on the fixing plates 303.

[0033] A rotating shaft 304 is rotatably connected to the inner wall of several fixed plates 303. Pulleys 305 are fixedly connected to the outer wall of both the rotating shafts 304 and the outer wall of the transmission shaft 302. A belt 306 is driven to the outer wall of each pulley 305. A turntable 307 is fixedly connected to the outer wall of the end of the rotating shaft 304 away from the pulleys 305. The pulleys 305 can drive the belt 306. When the lower pulley 305 rotates, it drives the belt 306 to move, causing the upper pulley 305 to rotate. Simultaneously, the pulleys 305 can... To prevent the belt 306 from falling off during transmission, a limiting shaft 308 is fixedly connected to the outer wall of the turntable 307. A connecting rod 309 is rotatably connected to the outer wall of the limiting shaft 308. Several brush plates 310 are slidably connected to the inner wall of the mounting base 1 near the connecting rod 309. A second limiting shaft 311 is fixedly connected to the outer wall of the brush plate 310. The outer wall of the second limiting shaft 311 is rotatably connected to the inner wall of the connecting rod 309. Through the brush plates 310, the surface of the passing welding wire can be cleaned to remove impurities from the surface of the welding wire.

[0034] One specific application of this embodiment is:

[0035] When the equipment is needed, the welding wire is passed through rollers 101 and 211 from the end furthest from the brush plate 310 and exits from the end closest to the brush plate 310. During the wire feeding process, it continuously passes through rollers 101 and 211, eventually becoming straight. When the diameter of the straightened welding wire needs to be controlled, the first motor 207 is started. The rotation of the first motor 207 drives the worm gear 206 to rotate, causing multiple worm wheels 205 to rotate simultaneously. The rotation of the worm wheels 205 drives the rotating rod 203 to rotate, which in turn drives the lifting rod 204 to move within its arc-shaped groove. Because the limiting groove 202 restricts the movement trajectory of the lifting rod 204, the arc-shaped upward movement of the lifting rod 204 can be converted into a straight up-and-down movement along the direction of the limiting groove 202. The up-and-down movement of the lifting rod 204 causes the top plate 208 to move up and down as a whole, thereby controlling the overall movement of rollers 211. When the threaded rod 209 is rotated, the locking block on the threaded rod sleeve 210 engages with the locking groove on the top plate 208. Therefore, the rotation of the threaded rod 209 causes the threaded rod sleeve 210 to slide within the top plate 208, thereby adjusting the height of the individual roller 211. The second motor 301 is then started. The rotation of the second motor 301 drives the transmission shaft 302 to rotate, causing the multiple pulleys 305 at the lower end to rotate simultaneously. The rotation of the lower pulleys 305 adjusts the belt... Rotation of 306 causes the upper pulley 305 to rotate, which in turn drives the rotating shaft 304 to rotate. When the rotating shaft 304 rotates, the turntable 307 rotates, and the limit shaft 308 makes an eccentric circular motion around the rotating shaft 304, which in turn drives the connecting rod 309 to move. The movement of the connecting rod 309 drives the limit shaft 311 to move, causing the brush plate 310 to slide back and forth in the mounting base 1. The movement of the brush plate 310 will continuously clean the passing welding wire and remove impurities from the surface of the welding wire.
