Description

Technical Field

[0001] This utility model belongs to the field of production and processing technology, and specifically relates to a steel plate loading device for the production of welded steel pipes. Background Technology

[0002] Welded steel pipes, also known as welded pipes, are steel pipes made by rolling and welding steel plates or strips. They are generally available in 6-meter lengths. The production process of welded steel pipes is simple, with high production efficiency, a wide variety of specifications, and low equipment investment. However, their strength is generally lower than that of seamless steel pipes. Smaller diameter welded pipes use straight seam welding, while larger diameter welded pipes mostly use spiral welding. According to the shape of the pipe ends, they are divided into round welded pipes and special-shaped (square, rectangular, etc.) welded pipes. According to different materials and uses, they are divided into welded steel pipes for mining fluid transportation, galvanized welded steel pipes for low-pressure fluid transportation, and electric welded steel pipes for belt conveyor idlers, etc.

[0003] A search revealed that Chinese Patent Publication No. CN216511225U, authorized on May 13, 2022, discloses a steel plate loading device for straight seam steel pipe production. The device includes a loading machine with a slide mounted on one side. It also includes a platform, a motion component, and a slide block, with the slide block slidably connected to the slide. Motion components are located on one side of both the slide and the slide block. Specifically relating to the field of straight seam steel pipe production technology, this steel plate loading device, by incorporating a motion component, a drive component, and a platform, allows the drive component to rotate via a turntable driving a gear shaft during steel plate loading. This drive component, in turn, drives a lead screw to rotate, which in turn moves a lead screw sleeve along the lead screw axial direction. The height of the platform can be adjusted to a lower position, making it easier for personnel to place the steel plate onto the platform, reducing labor intensity and minimizing the risk of machine or personnel injury due to errors during steel plate handling.

[0004] However, the device still has the following drawbacks: Although the adjustable platform height makes it easier for personnel to place steel plates on the platform and reduce their labor intensity, the steel plates will gradually shift during the feeding process. This shift may lead to uneven welds, which in turn affects the strength and sealing of the steel pipe. When the steel plates shift, the operators need to spend extra time adjusting them, which not only interrupts the production process but also reduces the overall production efficiency, further impacting production efficiency.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1-4 As shown, this utility model embodiment provides a steel plate feeding device for welded steel pipe production, including a base plate 1, a placement frame 2 is provided on the top of the base plate 1, a conveyor belt 3 is provided in the inner cavity of the placement frame 2, a gantry frame 4 is fixedly connected to the top of the placement frame 2, a housing 5 is provided at the bottom of the gantry frame 4, cylinders 6 are embedded on both sides of the top of the gantry frame 4, the output end of the cylinders 6 is connected to the housing 5 for transmission, a feeding mechanism 7 is provided on the left side of the placement frame 2, two clamping plates 8 are provided on the left side of the housing 5, and a driving mechanism 9 and a guiding mechanism 10 are provided in the inner cavity of the housing 5.

[0025] The above design, through the setting of the feeding mechanism 7, realizes the automatic pushing function of steel plates, eliminating the need for manual handling of steel plates, improving production efficiency and reducing labor costs. During the steel plate conveying process, the stable movement of the push block 73 in the guide groove 74 ensures the smoothness of steel plate conveying and avoids possible deviation or falling of steel plates during conveying. Through the setting of the drive mechanism 9, the synchronous and relative movement of the two clamping plates 8 is realized, thereby efficiently clamping the steel plates, which not only improves the clamping accuracy, but also ensures that the steel plates can be accurately located at the center of the conveyor belt 3, avoiding deviation of steel plates during conveying. Through the setting of the guide mechanism 10, it plays the role of limiting the movable plate 94, improving the stability of the movable plate 94 during movement. At the same time, the setting of the tension spring 103 can accelerate the movement of the limiting block 102, thereby enabling the clamping plates 8 to quickly fix the steel plates.

[0026] Specifically, such as Figures 1-3As shown, the feeding mechanism 7 includes a storage box 71 fixedly connected to the top left side of the placement frame 2. A guide groove 74 is provided on the left side of the storage box 71, and a through groove 75 is provided at the bottom right side of the storage box 71. An electric telescopic rod 72 is fixedly connected to the bottom of the placement frame 2. A push block 73 is drivenly connected to the output end of the electric telescopic rod 72, and the push block 73 is located inside the guide groove 74. This design, through the setting of the feeding mechanism 7, realizes the automatic pushing function of the steel plate, eliminating the need for manual handling of the steel plate, improving production efficiency, and reducing labor costs. During the steel plate conveying process, the stable movement of the push block 73 within the guide groove 74 ensures the smoothness of the steel plate conveying, preventing possible deviation or falling of the steel plate during conveying.

[0027] Specifically, such as Figures 1-4 As shown, the drive mechanism 9 includes a dual-axis motor 91 disposed within the inner cavity of the housing 5. Both output ends of the dual-axis motor 91 are connected to threaded rods 92. One end of the threaded rod 92 is rotatably connected to the housing 5. A threaded block 93 is threadedly connected to the surface of the threaded rod 92. Movable plates 94 are disposed on both sides of the inner cavity of the housing 5. One side of the threaded block 93 is fixedly connected to the movable plate 94. A connecting block 95 is fixedly connected to one side of the movable plate 94. One side of the connecting block 95 extends through to the outside of the housing 5 and is fixedly connected to the clamping plate 8. This design, through the arrangement of the drive mechanism 9, achieves synchronous and relative movement of the two clamping plates 8, thereby efficiently clamping the steel plate. This not only improves the clamping accuracy but also ensures that the steel plate is accurately positioned at the center of the conveyor belt 3, preventing the steel plate from shifting during the conveying process.

[0028] Specifically, as follows Figures 1-4 As shown, the guiding mechanism 10 includes a limiting rod 101 fixedly connected to the bottom of the inner cavity of the housing 5. Two limiting blocks 102 are slidably connected to the surface of the limiting rod 101. One side of the limiting block 102 is fixedly connected to the movable plate 94. A tension spring 103 is sleeved on the surface of the limiting rod 101, and both ends of the tension spring 103 are fixedly connected to the limiting block 102. This design, through the setting of the guiding mechanism 10, serves to limit the movement of the movable plate 94, improving the stability of the movable plate 94 during movement. Simultaneously, the tension spring 103 accelerates the movement of the limiting block 102, thereby enabling the clamping plate 8 to quickly fix the steel plate.

[0029] Specifically, such as Figures 1-4As shown, a mounting base 11 is fitted on the surface of the dual-axis motor 91. A bolt is threaded onto one side of the mounting base 11. The dual-axis motor 91 is detachably connected to the housing 5 by the bolt. A rubber block 12 is fixedly connected to one side of the clamping plate 8. The rubber block 12 is rectangular in shape. Support blocks 13 are fixedly connected to both sides of the bottom of the storage box 71. One side of the support block 13 is fixedly connected to the placement rack 2. A box body 14 is fixedly connected to the top of the bottom plate 1. Box doors 15 are rotatably connected to both sides of the front surface of the box body 14. The above design, through the cooperation of mounting base 11 and bolts, serves to fix the dual-axis motor 91, while facilitating disassembly and maintenance by the user. The rubber block 12 protects the clamping plate 8, reduces friction between the steel plate and the clamping plate 8, extends the service life of the clamping plate 8, and makes the surface of the steel plate less prone to wear. The support block 13 supports the storage box 71, improving the stability of the storage box 71 when placed. The cooperation of box body 14 and box door 15 serves to store the processed parts, making it convenient for the user to retrieve them.

[0030] The working principle of the steel plate loading device for welded steel pipe production proposed in this embodiment is as follows:

[0031] When using the device, the user places steel plates into the inner cavity of the storage box 71. Then, to facilitate the conveying of the steel plates, the user activates the electric telescopic rod 72. The output end of the electric telescopic rod 72 drives the push block 73 to move to the right in the inner cavity of the storage box 71. The push block 73 will drive the steel plate at the bottom of the inner cavity of the storage box 71 to move through the through groove 75 to the surface of the conveyor belt 3, thus achieving the function of conveying the steel plates.

[0032] Furthermore, by activating cylinder 6, the output end of cylinder 6 will drive housing 5 to move downward, so that the bottom of housing 5 is in contact with conveyor belt 3. As the steel plate moves continuously on the surface of conveyor belt 3, one side of the steel plate will come into contact with housing 5, thereby keeping the steel plate vertically placed.

[0033] Furthermore, the dual-axis motor 91 is started. The output end of the dual-axis motor 91 drives the threaded rod 92 to rotate. When the threaded rod 92 rotates, it drives the threaded block 93 to move, so that the two threaded blocks 93 move relative to each other. The threaded block 93 drives the movable plate 94 to move. The movable plate 94 drives the limit block 102 to slide on the surface of the limit rod 101. When the limit block 102 moves, it drives the tension spring 103 to compress. At the same time, when the movable plate 94 moves, it drives the two clamping plates 8 to move relative to each other through the connecting block 95, so as to clamp the steel plate and keep the steel plate at the center of the conveyor belt 3, ensuring that the steel plate is not easily deviated when moving.

[0034] Furthermore, by reversing the dual-axis motor 91, the steel plate can be released from its fixation. Then, by starting the cylinder 6, the housing 5 can be moved upward, allowing the steel plate to continue moving, which is convenient for the user to process the steel plate later.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
