Description

Technical Field

[0001] This utility model relates to the field of pipe welding machines, specifically a straight seam pipe welding machine. Background Technology

[0002] A straight seam welded pipe machine is a specialized piece of equipment used to process round tubular metal strips (steel strips) with longitudinal weld seams. This equipment uses welding technology to fuse the curled edges of the tubular steel strips into one piece, and then, after finishing processes, finally obtains straight seam welded pipes with accurate dimensions and reliable strength.

[0003] Under current technological conditions, some manufacturers, due to small order volumes, typically use small semi-automatic straight seam welded pipe machines for production. During operation, workers first need to slip the tubular steel strip onto the support rod, then use the clamping mechanism to periodically fix its edge position, and then start the welding mechanism to complete the welding process.

[0004] However, in the process of fixing tubular steel strips, such equipment often requires workers to manually lift the steel strips and align the two ends of the weld. For steel strips that are long and have a certain degree of elasticity, it is difficult to ensure that the weld is always in the correct position by relying solely on manual alignment. This can easily lead to the weld area being skewed and unable to fit tightly. This problem can then cause the diameters of the two ends of the pipe to be inconsistent after welding, affecting the dimensional accuracy and overall quality of the product. Therefore, a straight seam welded pipe machine is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background art, this utility model proposes a straight seam welded pipe machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a straight seam welded pipe machine, including a support frame, a clamping mechanism is provided on the top of the support frame, a welding mechanism is provided on the top side of the clamping mechanism, a support column is fixedly installed on the side wall of the support frame located on the bottom side of the clamping mechanism, a rectangular shell is provided on the side wall of the support frame located on the bottom side of the support column, a sliding plate is slidably connected to the middle of the rectangular shell, a support plate is fixedly connected to the end side of the sliding plate, a rubber pad is in contact with the side wall of the support plate, a concave plate is slidably connected to the outer wall of the support frame, and the side wall of the end of the rectangular shell is specifically fixedly connected to the side wall of the end of the concave plate.

[0009] Preferably, the inner wall of the rubber pad is provided with a rectangular groove, and a movable block is elastically connected to the inner wall of the rectangular groove by a spring. The outer wall of the movable block is slidably connected to the inner wall of the rectangular groove. One end of the spring is fixed to the inner wall of the movable block, and the other end of the spring is fixed to the inner wall of the rectangular groove. The side wall of the movable block is fixed to the top side of the hinge block.

[0010] Preferably, the rubber pad has a connecting strip fixed to its side wall, and the tray has a connecting groove on its side wall, with the connecting strip inserted into the inner wall of the connecting groove.

[0011] Preferably, the rectangular shell, support plate, connecting plate, sliding plate, and hinge block are provided in multiple sets, and the multiple sets of rectangular shell, support plate, connecting plate, sliding plate, and hinge block are symmetrically arranged with the center line of the connecting plate as the axis of symmetry. The bottom ends of the multiple sets of connecting plates are rotatably connected to the outer wall of the end of the connecting plate.

[0012] Preferably, the inner wall of the insertion groove and the outer wall of the insertion strip are both T-shaped, and the inner wall of the insertion groove and the outer wall of the insertion strip are interference fit.

[0013] The advantages of this utility model are: through the cooperation between the shell, support plate, connecting plate, connecting plate, push plate and sliding plate, the tubular steel strip to be welded can be lifted and clamped without the need for manual adjustment by workers, which improves the fixing efficiency and reduces the risk of the weld area of ​​the tubular steel strip being skewed and unable to fit tightly.

It solves the problem of manual alignment failing to ensure the weld seam is always in the correct position, which can easily lead to misalignment and poor fit. This misalignment can result in inconsistent diameters at both ends of the welded pipe, affecting product dimensional accuracy and overall quality. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail. This application discloses a straight seam welded pipe machine. (Refer to...) Figure 1 - Figure 4A straight seam welded pipe machine includes a support frame 1, a clamping mechanism 2 at the top of the support frame 1, a welding mechanism 3 on the top side of the clamping mechanism 2, a support column 4 fixedly installed on the side wall of the support frame 1 at the bottom side of the clamping mechanism 2, a rectangular shell 5 at the bottom side of the support column 4, a sliding plate 14 slidably connected to the middle of the rectangular shell 5, a support plate 6 fixedly connected to the end of the sliding plate 14, a rubber pad 17 contacting the side wall of the support plate 6, a concave plate 10 slidably connected to the outer wall of the support frame 1, and the side wall of the end of the rectangular shell 5 specifically fixedly connected to the side wall of the end of the concave plate 10. During operation, the height of the concave plate 10 and the rectangular shell 5 can be adjusted in advance according to the needs of the tubular steel strip, so that during processing, the tubular steel strip is fitted onto the support frame 1. When the product is placed on the outer wall of the support column 4, the support plate 6 will support the product without the need for manual lifting by the worker. This continues until the product is completely placed on the outer wall of the support column 4. Then, the sliding plate 14 can be moved, which will move the support plate 6. The support plate 6 will move the rubber pad 17, clamping the product and ensuring that the weld area of ​​the product is joined together. At this point, the clamping mechanism 2 can be activated to press down and fix the weld of the product. Finally, the welding mechanism 3 is activated to perform the welding operation. Through the above operations, when placing the product, the worker does not need to manually adjust the opening and closing size of the weld ends repeatedly, which improves the fixing efficiency and reduces the risk of the weld area of ​​the tubular steel strip being skewed or unable to fit tightly.

[0020] Reference Figure 3 and Figure 5 The rectangular shell 5 has a through groove 23 at its bottom. A hinge block 19 is slidably connected to the middle of the through groove 23. The top side of the hinge block 19 is fixed to the top side of the slide plate 14. A connecting plate 8 is rotatably connected to the outer wall of the bottom of the hinge block 19. A connecting plate 7 is rotatably connected to the inner wall of the bottom of the connecting plate 8. A push plate 9 is fixed to the side wall of the connecting plate 7. During operation, when it is necessary to control the movement of the support plate 6, simply press the push plate 9 to move the connecting plate 7. At this time, the angle of the connecting plate 8 will change, and one end of the connecting plate 8 will rotate with the connecting plate 7, while the other end of the connecting plate 8 will rotate with the push plate 9, causing the hinge block 19 to slide on the inner wall of the through groove 23. When it is necessary to release, simply stop pressing the push plate 9, which improves the convenience of operation.

[0021] Reference Figure 1 - Figure 3A fixing block 12 is fixedly connected to the side wall of the support frame 1. A threaded rod 11 is rotatably connected to the inner wall of the fixing block 12. The outer wall of the threaded rod 11 is threadedly connected to the inner wall of the concave plate 10. A sliding groove 13 is provided on the side wall of the support frame 1. A slider 22 is fixedly connected to the inner wall of the concave plate 10. The outer wall of the slider 22 is slidably connected to the inner wall of the sliding groove 13. During operation, by rotating the fixing block 12, the concave plate 10 threadedly connected to the outer wall of the fixing block 12 will move linearly up and down on the outer wall of the support frame 1. This allows the height of the concave plate 10 and the rectangular shell 5 to be adjusted, so that products of different diameters can be lifted and clamped. In addition, the fixing block 12 ensures the stability of the rotation of the threaded rod 11. It should be noted that the outer wall of the threaded rod 11 and the inner wall of the concave plate 10 have an axial self-locking characteristic, reducing the risk of the concave plate 10 sliding automatically.

[0022] Reference Figure 3 and Figure 5 A rectangular groove 18 is provided on the inner wall of the rubber pad 17. A movable block 20 is elastically connected to the inner wall of the rectangular groove 18 by a spring 21. The outer wall of the movable block 20 is slidably connected to the inner wall of the rectangular groove 18. One end of the spring 21 is fixed to the inner wall of the movable block 20, and the other end of the spring 21 is fixed to the inner wall of the rectangular groove 18. The side wall of the movable block 20 is fixed to the top side of the hinge block 19. When working, when the hinge block 19 moves, it will drive the movable block 20 to slide on the inner wall of the rectangular groove 18. At the same time, the movable block 20 will also squeeze the spring 21. When the push plate 9 is stopped, the spring 21 will drive the hinge block 19 to reset through its own elasticity, which improves the convenience of operation.

[0023] Reference Figure 4 A connector strip 16 is fixed to the side wall of the rubber pad 17, and a connector groove 15 is opened on the side wall of the support plate 6. The connector strip 16 is inserted into the inner wall of the connector groove 15. When the rubber pad 17 needs to be replaced after a period of use, it can be moved by pulling it directly. The rubber pad 17 will drive the connector strip 16 to move until the connector strip 16 is disengaged from the inner wall of the connector groove 15. During installation, the connector strip 16 can be directly inserted into the inner wall of the connector groove 15. The installation process is quick and convenient.

[0024] Reference Figure 1 and Figure 3 The rectangular shell 5, support plate 6, connecting plate 8, sliding plate 14, and hinge block 19 are provided in multiple sets. The multiple sets of rectangular shell 5, support plate 6, connecting plate 8, sliding plate 14, and hinge block 19 are symmetrically arranged with the center line of the connecting plate 7 as the axis of symmetry. The bottom ends of the multiple sets of connecting plates 8 are rotatably connected to the outer wall of the end of the connecting plate 7. During operation, the multiple sets of rectangular shell 5, support plate 6, connecting plate 8, sliding plate 14, and hinge block 19 can ensure that the connecting plate 7 can move up and down stably, and the multiple sets of support plates 6 can also stably perform clamping operations.

[0025] Reference Figure 4 The inner wall of the insertion groove 15 and the outer wall of the insertion strip 16 are both set to T-shape. The inner wall of the insertion groove 15 and the outer wall of the insertion strip 16 are interference fit. During operation, by setting the inner wall of the insertion groove 15 and the outer wall of the insertion strip 16 to T-shape, the risk of the insertion strip 16 disengaging from the inner wall of the insertion groove 15 is reduced. The interference fit can further improve the stability of the rubber pad 17 installation.

[0026] Working principle: During processing, when the tubular steel strip is fitted onto the outer wall of the support column 4, the pallet 6 supports the product, eliminating the need for manual lifting by the worker. This continues until the product is fully placed on the outer wall of the support column 4. Then, simply pressing the push plate 9 moves the connecting plate 7. At this point, the angle of the connecting plate 8 changes, and one end of the connecting plate 8 rotates relative to the connecting plate 7, while the other end rotates relative to the push plate 9. This causes the hinge block 19 to slide along the inner wall of the through groove 23. Simultaneously, the hinge block 19 moves the sliding plate 14, which in turn moves the pallet 6. The pallet 6 will move the rubber pad 17 to clamp the product and ensure that the weld seam area of ​​the product is joined together. At this time, the clamping mechanism 2 can be activated to press down and fix the weld seam of the product. Finally, the welding mechanism 3 is activated to perform the welding operation. When the hinge block 19 moves, it will drive the moving block 20 to move and stretch the spring 21. When the clamping mechanism 2 fixes the product, the push plate 9 can be stopped. The spring 21 will reset the pallet 6 through its own elasticity. At this time, the pallet 6 only has the function of lifting. After the processing is completed, the clamping mechanism 2 can be released and the product can be taken out.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
