Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and in particular relates to a flux-cored material addition device for wear-resistant steel plate surfacing. Background Technology

[0002] Wear-resistant steel plates are widely used in equipment in industries such as mining, metallurgy, power, and cement. Especially in high-wear environments, such as the manufacturing and repair of equipment components like crushers, conveyor belts, and bucket wheels, wear-resistant steel plates have high wear resistance, which can effectively extend the service life of equipment and reduce maintenance costs.

[0003] If the flux-cored wire is not added evenly, some areas may lack the necessary alloy components during the welding process, resulting in fluctuations in the quality of the weld overlay. Therefore, a feeding wheel is needed to feed the wire evenly. However, if the feeding wheel becomes blocked, the supply of flux-cored wire will be interrupted or uneven, which will directly affect the wire feeding during the welding process, resulting in discontinuous welding or unstable quality. Therefore, we propose a flux-cored wire addition device for wear-resistant steel plate overlay welding. Utility Model Content

[0004] The purpose of this invention is to provide a flux core addition device for wear-resistant steel plate overlay welding. A pair of semicircular blocks are squeezed by a spring, causing the semicircular blocks to rise. As the semicircular blocks move, they also drive the vibrating block to move, which strikes the inner wall of the groove of the feeding wheel, thus solving the problem of possible blockage of the feeding wheel.

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

[0006] This utility model is a flux core addition device for wear-resistant steel plate overlay welding, including a material cylinder one, a material cylinder two fixedly connected to the outer wall of the material cylinder one, a feeding mechanism on the material cylinder two, and a disassembly mechanism on the material cylinder two;

[0007] The feeding mechanism includes a fixed frame fixedly connected to the outer wall of the second material cylinder. A motor is fixedly connected to the outer wall of the fixed frame. A rotating shaft is fixedly connected to the output shaft of the motor via a coupling. A feeding wheel is fixedly connected to the side of the rotating shaft away from the motor. A fixed frame is fixedly connected to the inner wall of the feeding wheel. A fixed shaft is fixedly connected to the inner wall of the fixed frame. A fixed block is fixedly connected to the outer wall of the fixed shaft. A telescopic rod is fixedly connected to the top of the fixed block. A semicircular block is fixedly connected to the side of the telescopic rod away from the fixed block. A spring is fixedly connected to the side of the semicircular block near the telescopic rod. A vibration block is fixedly connected to the outer wall of the semicircular block.

[0008] Furthermore, a telescopic rod is fixedly connected to the outer wall of the vibrating block, the outer wall of the rotating shaft is rotatably connected to the inner wall of the fixed frame, the outer wall of the fixed shaft is rotatably connected to the inner wall of the feeding wheel, and the end of the spring away from the semicircular block is fixedly connected to the outer wall of the fixed block.

[0009] Furthermore, the first telescopic rod is located inside the first spring, the outer wall of the vibrating block is in contact with the inner wall of the feeding wheel, and the second telescopic rod is fixedly connected to the outer wall of the fixed block on the side away from the vibrating block.

[0010] Furthermore, the disassembly mechanism includes a positioning block fixedly connected to the outer wall of the fixed frame. There are two positioning blocks in total, and a positioning rod is inserted into the inner wall of the positioning block.

[0011] Furthermore, a fixing plate is fixedly connected to the outer wall of the positioning rod, and a feeding pipe is fixedly connected to the bottom of the fixing plate.

[0012] Furthermore, a third fixed frame is fixedly connected to the outer wall of the fixed frame, and two third fixed frames are provided in total. A third telescopic rod is fixedly connected to the inner wall of the third fixed frame, and two third telescopic rods are provided in total. A clamping block is fixedly connected to the outer wall of the third telescopic rod. The inner wall of the clamping block is engaged with the outer wall of the fixed plate, and the outer wall of the clamping block is slidably connected to the inner wall of the third fixed frame.

[0013] Furthermore, a spring is fixedly connected to the side of the clamping block near the telescopic rod three, and the side of the spring two away from the clamping block is fixedly connected to the inner wall of the fixed frame three. The telescopic rod three is located inside the spring two.

[0014] Furthermore, a sliding groove is provided inside the fixed frame three, and a slider is fixedly connected to the outer wall of the clamping block, with the outer wall of the slider slidably connected to the inner wall of the sliding groove.

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

[0016] 1. This utility model incorporates a feeding wheel. First, the flux core is fed into the fixed frame through material cylinder one and material cylinder two. Then, the motor is started, driving the rotating shaft to rotate. As the rotating shaft rotates, it also drives the feeding wheel to rotate. Since the fixed shaft and the fixed frame are fixedly connected, neither the fixed shaft nor the fixed block will rotate. The rotation of the feeding wheel will drive the fixed frame two to rotate. This mechanism can tap the inside of the feeding wheel to prevent the flux core from clogging the feeding wheel, ensuring the uniformity and continuity of flux core feeding and improving the stability of welding quality.

[0017] 2. This utility model features a feeding pipe. When the feeding pipe needs to be removed, first manually move the two sliders to the sides inside the chute, causing the clamping block to slide inside the fixed frame three, thereby squeezing the telescopic rod three and the spring two. Then, the fixing plate can be removed, and the positioning rod can be moved away from the positioning block. Then, a new feeding pipe can be replaced. This mechanism allows for quick installation and disassembly of the feeding pipe. If the feeding pipe malfunctions or needs cleaning, the disassembly design can reduce production downtime and production losses caused by maintenance and pipe replacement.

[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

Detailed Implementation

[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 1-7 As shown, this utility model is a flux core addition device for wear-resistant steel plate overlay welding, including a material cylinder 101, a material cylinder 2 102 fixedly connected to the outer wall of the material cylinder 101, a feeding mechanism 2 provided on the material cylinder 2 102, and a disassembly mechanism 3 provided on the material cylinder 2 102.

[0031] The feeding mechanism 2 includes a fixed frame 201 fixedly connected to the outer wall of the material cylinder 102. A motor 202 is fixedly connected to the outer wall of the fixed frame 201. The output shaft of the motor 202 is fixedly connected to a rotating shaft 203 via a coupling. A feeding wheel 204 is fixedly connected to the side of the rotating shaft 203 away from the motor 202. The feeding wheel 204 has a hollow interior and is equipped with vibrating components to prevent it from being blocked. A fixed frame 205 is fixedly connected to the inner wall of the feeding wheel 204. A fixed shaft 206 is fixedly connected, and a fixed block 207 is fixedly connected to the outer wall of the fixed shaft 206. A telescopic rod 208 is fixedly connected to the top of the fixed block 207. A second fixed frame 205 is provided, which has a concave-convex design. During the rotation of the second fixed frame 205, it will cyclically compress and release the semicircular block 209, giving the semicircular block 209 a vibration function. The side of the telescopic rod 208 away from the fixed block 207 is fixedly connected to the semicircular block 209, and the side of the semicircular block 209 closer to the telescopic rod 208 is fixedly connected to the first telescopic rod 208. A spring 210 is fixedly connected to the side. A vibrating block 211 is fixedly connected to the outer wall of the semicircular block 209. A telescopic rod 212 is fixedly connected to the outer wall of the vibrating block 211. By setting the vibrating block 211, when the semicircular block 209 moves, it will drive the vibrating block 211 to move, thereby causing the vibrating block 211 to strike the inner wall of the feeding wheel 204, causing the drug core on the feeding wheel 204 to be knocked down. The outer wall of the rotating shaft 203 is rotatably connected to the inner wall of the fixed frame 201, and the outer wall of the fixed shaft 206 is rotatably connected to the inner wall of the feeding wheel 204. The end of spring 210 away from the semicircular block 209 is fixedly connected to the outer wall of the fixed block 207. The telescopic rod 208 is located inside spring 210. By setting spring 210, the semicircular block 209 will be squeezed. When the semicircular block 209 moves to the protruding part of the fixed frame 205, the semicircular block 209 will move due to the presence of spring 210. The outer wall of the vibrating block 211 contacts the inner wall of the feeding wheel 204. The side of the telescopic rod 212 away from the vibrating block 211 is fixedly connected to the outer wall of the fixed block 207.

[0032] The disassembly mechanism 3 includes two positioning blocks 303 fixedly connected to the outer wall of the fixed frame 201. A positioning rod 302 is inserted into the inner wall of each positioning block 303, and a fixing plate 301 is fixedly connected to the outer wall of the positioning rod 302. By setting the positioning rod 302, during installation, the positioning rod 302 is inserted into the positioning block 303 to initially position the component being installed, preventing positional deviations during installation. A feed pipe 310 is fixedly connected to the bottom of the fixing plate 301. There are two fixed frames 304. The inner wall of the fixed frame 304 is fixedly connected to the telescopic rod 305. There are two telescopic rods 305. The outer wall of the telescopic rod 305 is fixedly connected to the clamping block 306. By setting the clamping block 306, the shape of the groove inside the clamping block 306 corresponds to the shape of the fixed plate 301, so that the fixed plate 301 can be clamped and fixed. The inner wall of the clamping block 306 is engaged with the outer wall of the fixed plate 301, and the outer wall of the clamping block 306 is slidably connected to the inner wall of the fixed frame 304.

[0033] A spring 307 is fixedly connected to the side of the clamping block 306 near the telescopic rod 305. The side of the spring 307 away from the clamping block 306 is fixedly connected to the inner wall of the fixed frame 304. The telescopic rod 305 is located inside the spring 307. A sliding groove 308 is provided inside the fixed frame 304. A slider 309 is fixedly connected to the outer wall of the clamping block 306. By setting the slider 309, the slider 309 slides inside the sliding groove 308, which drives the clamping block 306 to move and squeeze the telescopic rod 305 and the spring 307. The outer wall of the slider 309 is slidably connected to the inner wall of the sliding groove 308.

[0034] One specific application of this embodiment is:

[0035] First, the drug core is fed into the fixed frame 201 through the first cylinder 101 and the second cylinder 102. Then, the motor 202 is started, driving the rotating shaft 203 to rotate. As the rotating shaft 203 rotates, it also drives the feeding wheel 204 to rotate. Since the fixed shaft 206 is fixedly connected to the fixed frame 201, neither the fixed shaft 206 nor the fixed block 207 will rotate. As the feeding wheel 204 rotates, it also drives the second fixed frame 205 to rotate. While the second fixed frame 205 is rotating, it intermittently splits in half. The circular block 209 compresses the telescopic rod 208 and the spring 210. When the vibrating block 211 moves to the groove of the feeding wheel 204, due to the shape of the fixed frame 205, the spring 210 compresses the semi-circular block 209, causing it to rise. The movement of the semi-circular block 209 also moves the vibrating block 211, striking the inner wall of the groove in the feeding wheel 204. This mechanism can strike the inside of the feeding wheel 204, preventing the drug core from clogging it. 4. To ensure the uniformity and continuity of the flux core feeding and improve the stability of welding quality, when it is necessary to remove the feed tube 310, first manually move the two sliders 309 to both sides inside the slide groove 308, causing the clamping block 306 to slide inside the fixed frame 304, thereby squeezing the telescopic rod 305 and the spring 307. Then, the fixed plate 301 can be removed, moving the positioning rod 302 away from the positioning block 303. Then, replace the feed tube 310 with a new one, and place the positioning rod 302 on the new fixed plate 301. Insert 02 into the positioning block 303, and then place the fixing plate 301 between the two clamping blocks 306. Then release the slider 309. Due to the reaction force of the second spring 307, it will continue to squeeze the clamping block 306, thereby clamping and fixing the fixing plate 301. This mechanism can quickly install and disassemble the feed pipe 310. If the feed pipe 310 malfunctions or needs to be cleaned, the disassembly design can reduce production downtime and reduce production losses caused by maintenance and pipe replacement.
