Description

Technical Field

[0001] The present invention relates to the technical field of welded pipe processing, and particularly to an efficient sawing device for straight seam welded pipes. Background Art

[0002] A straight seam welded pipe is formed by deforming a hot-rolled coil into a smooth cylindrical shape through a forming machine, and then welding it using the skin effect and proximity effect of high-frequency current or an arc burning under a flux layer, so that the edges of the pipe blank are heated and melted, and fused under a certain extrusion force, and finally cooled and formed. Among them, the pipe blank edge melted by high-frequency current is called a high-frequency straight seam welded pipe, and the one melted by an arc is called a submerged arc welded pipe for straight seams. During the production process of straight seam welded pipes, cutting is required according to the length required by customers. For example, in the construction industry, straight seam welded pipes of specific lengths may be required for structural support, and a sawing device can ensure that the length of each welded pipe meets the requirements of the building design. Herein, the present invention proposes an efficient sawing device for straight seam welded pipes.

[0003] According to the search, the Chinese patent document, publication number: CN213195875U, discloses a pipe cutting device for the production of submerged arc welded pipes for straight seams. By the cooperation between a rotating block, a support rod, a cross bar, a rotating member, a vertical rod, a circular block, a fixing plate, a chute and a slider, the descending speed of the cutting motor can be reduced, so that the cutting force of the cutting wheel on the welded pipe can be reasonably controlled, the cutting wheel can be effectively protected, and at the same time, the cutting quality can be improved. However, during the actual use of this device, first, when cutting welded pipes of different sizes, it is necessary to use sleeve columns of different sizes for installation and fixation, so not only the disassembly and assembly process is relatively complex, but also unnecessary production costs are increased; in addition, since parts such as the cutting motor and the connecting frame of this device are in a relatively fixed state, the position to be cut of the welded pipe cannot be accurately adjusted, and it depends on manual positioning with low accuracy and low efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an efficient sawing device for straight seam welded pipes, which has the advantages of simple operation, strong applicability, high positioning accuracy and improved production efficiency, and solves the above technical problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An efficient straight-seam welded pipe sawing device includes a base. A driving motor is fixedly installed on the right side surface of the base. A first chute is opened inside the base. A first slider and a first threaded rod are installed inside the first chute. A workbench is fixedly installed on the top surface of the first slider. A base is fixedly installed on the top surface of the workbench. A V-shaped groove is opened on the outer side surface of the base. A second chute is opened inside the base. A second slider is slidably installed inside the second chute. A second threaded rod is installed on the top surface of the second slider. A handle is fixedly installed at the top end of the second threaded rod. A vertical plate is fixedly installed on the top surface of the base. A top plate is fixedly installed on the right side surface of the vertical plate. A cylinder is fixedly installed on the top surface of the top plate. The output shaft of the cylinder is fixedly connected to a baffle. A limiting rod is fixedly installed on the top surface of the baffle. A sawing machine body is fixedly installed on the bottom surface of the baffle.

[0007] Preferably, first limiting blocks are arranged on both sides of the first slider, and both the first slider and the first limiting blocks are slidably installed inside the first chute.

[0008] Through the above technical solution, when the first slider and the first limiting blocks slide inside the first chute, the first slider can drive parts such as the workbench and the welded pipe to be cut to move. Therefore, the positioning accuracy of the welded pipe cutting can be efficiently controlled and improved, and the work efficiency can be improved. At the same time, the first limiting blocks can also effectively limit the moving position of the first slider to prevent it from falling off and other situations, improving the overall stability.

[0009] Preferably, the output shaft of the driving motor is fixedly connected to the right end of the first threaded rod, and the first slider is threadedly connected to the outer side surface of the first threaded rod.

[0010] Through the above technical solution, when the driving motor is started, the output shaft of the driving motor can drive the first threaded rod to rotate. The first threaded rod can then drive parts such as the first slider to slide inside the first chute, and then the position of parts such as the welded pipe to be cut can be adjusted, facilitating the positioning and processing of the staff and improving the overall practicability of the device.

[0011] Preferably, the number of both the base and the V-shaped groove is two, and rubber pads are installed inside both of the two V-shaped grooves.

[0012] Through the above technical solution, the welded pipe to be cut is passed through the two V-shaped grooves and installed inside them. The V-shaped grooves can be applicable to welded pipes of various different diameters, and the rubber pads can further improve the installation stability of the welded pipe, and at the same time can also avoid damaging the outer surface of the welded pipe, improving the overall applicability of the device.

[0013] Preferably, the number of the second sliding grooves, the second sliders, the second threaded rods and the handles are all set to be two, and the two second threaded rods are respectively threadedly connected to the interiors of the two bases.

[0014] Through the above technical solution, after the welded pipe to be cut is installed inside the two V-shaped grooves, turning the handle can drive the second threaded rod to rotate, and the second threaded rod can further drive the second slider to move inside the second sliding groove. Therefore, the second slider can press and fix the welded pipe, improving the overall stability of the device.

[0015] Preferably, a limiting ring is provided at the bottom end of the second threaded rod, and the limiting ring is rotatably installed inside the second slider.

[0016] Through the above technical solution, when turning the handle to drive the second threaded rod to rotate, the second threaded rod also drives the limiting ring to rotate inside the second slider. Therefore, it can not only drive the second slider to move inside the second sliding groove, but also the limiting ring can effectively limit the position of the second threaded rod to prevent it from falling off or other situations, improving the overall stability.

[0017] Preferably, the number of the limiting rods is set to be two, and second limiting blocks are fixedly installed on the outer sides of the two limiting rods.

[0018] Through the above technical solution, when the cylinder is started, the output shaft of the cylinder can drive parts such as the baffle plate and the sawing machine body to move in the vertical direction. Therefore, the welded pipe can be efficiently sawed. At the same time, the two limiting rods can further increase the overall stability of the device, and the multiple second limiting blocks can effectively limit the moving paths of parts such as the limiting rods and the baffle plate to avoid situations such as excessive movement, ensuring the normal operation of the device.

[0019] Preferably, a support is fixedly installed on the top surface of the workbench, a hose nozzle is installed inside the support, and one end of the hose nozzle away from the workbench is connected to a water delivery device.

[0020] Through the above technical solution, the water delivery device can be set as parts such as a water pump. The water pump can spray the coolant on the surface of the welded pipe through the hose nozzle. Therefore, when the welded pipe is sawed, the coolant can quickly reduce the temperature of the cutting blade, reduce the wear degree of the blade, and improve the overall service life of the device.

[0021] Compared with the prior art, the present invention provides an efficient straight-seam welded pipe sawing device, having the following beneficial effects:

[0022] 1. In the present invention, the welding pipe to be cut is passed through two V-shaped grooves and installed inside them. The V-shaped grooves can be applicable to welding pipes of various different diameters. Moreover, the rubber pads can further improve the stability of the installation of the welding pipe, and at the same time, they can also avoid damaging the outer surface of the welding pipe, improving the overall applicability of the device. After that, by rotating the two handles, the second threaded rod can be driven to rotate. The second threaded rod can then drive the second slider to move inside the second chute. The second slider can thus press and fix the welding pipe. At the same time, the limiting ring can effectively limit the position of the second threaded rod to prevent it from falling off or other situations, improving the overall stability.

[0023] 2. In the present invention, by starting the driving motor, the output shaft of the driving motor can drive the first threaded rod to rotate. The first threaded rod can then drive parts such as the first slider to slide inside the first chute, and thus the position of parts such as the welding pipe to be cut can be adjusted. Therefore, the positioning accuracy of the welding pipe cutting can be efficiently controlled and improved, improving the working efficiency. By starting the cylinder, the output shaft of the cylinder can drive parts such as the baffle and the sawing machine body to move in the vertical direction. Therefore, the welding pipe can be efficiently sawed. At the same time, the two limiting rods can further increase the overall stability of the device, and the multiple second limiting blocks can effectively limit the moving paths of parts such as the limiting rods and the baffle to avoid situations such as excessive movement, ensuring the normal operation of the device.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 - 4 , a high-efficiency straight-seam welded pipe sawing device, which includes a base 1. A driving motor 2 is fixedly installed on the right side surface of the base 1. A first chute 3 is opened inside the base 1. A first slider 4 and a first threaded rod 5 are installed inside the first chute 3. A workbench 6 is fixedly installed on the top surface of the first slider 4. A base 7 is fixedly installed on the top surface of the workbench 6. A V-shaped groove 8 is opened on the outer side surface of the base 7. A second chute 9 is opened inside the base 7. A second slider 10 is slidably installed inside the second chute 9. A second threaded rod 11 is installed on the top surface of the second slider 10. A handle 12 is fixedly installed at the top end of the second threaded rod 11. A vertical plate 13 is fixedly installed on the top surface of the base 1. A top plate 14 is fixedly installed on the right side surface of the vertical plate 13. An air cylinder 15 is fixedly installed on the top surface of the top plate 14. The output shaft of the air cylinder 15 is fixedly connected to a baffle 16. A limiting rod 17 is fixedly installed on the top surface of the baffle 16. A sawing machine body 18 is fixedly installed on the bottom surface of the baffle 16.

[0031] Specifically, first limit blocks 19 are arranged on both sides of the first slider 4, and both the first slider 4 and the first limit blocks 19 are slidably installed inside the first chute 3. The advantage is that with this structure, when the first slider 4 and the first limit blocks 19 slide inside the first chute 3, the first slider 4 can drive parts such as the workbench 6 and the welded pipe to be cut to move. Therefore, the positioning accuracy of the welded pipe cutting can be efficiently controlled and improved, and the work efficiency can be improved. At the same time, the first limit blocks 19 can also effectively limit the moving position of the first slider 4 to prevent it from falling off and other situations, improving the overall stability.

[0032] Specifically, the output shaft of the driving motor 2 is fixedly connected to the right end of the first threaded rod 5, and the first slider 4 is threadedly connected to the outer side surface of the first threaded rod 5. The advantage is that with this structure, when the driving motor 2 is started, the output shaft of the driving motor 2 can drive the first threaded rod 5 to rotate. The first threaded rod 5 can then drive parts such as the first slider 4 to slide inside the first chute 3, and further adjust the position of parts such as the welded pipe to be cut, facilitating the positioning and processing by the staff, and improving the overall practicality of the device.

[0033] Specifically, both the base 7 and the V-shaped grooves 8 are provided with two, and rubber pads 20 are installed inside both of the V-shaped grooves 8. The advantage is that by passing the welded pipe to be cut through the two V-shaped grooves 8 and installing it inside, the V-shaped grooves 8 can be applicable to welded pipes of various different diameters, and the rubber pads 20 can further improve the stability of the installation of the welded pipe, and at the same time can also avoid damaging the outer surface of the welded pipe, improving the overall applicability of the device.

[0034] Specifically, both the second sliding grooves 9, the second sliding blocks 10, the second threaded rods 11 and the handles 12 are provided with two, and the two second threaded rods 11 are respectively threadedly connected to the inside of the two bases 7. The advantage is that after installing the welded pipe to be cut inside the two V-shaped grooves 8 through this structure, turning the handle 12 can drive the second threaded rod 11 to rotate, and the second threaded rod 11 can further drive the second sliding block 10 to move inside the second sliding groove 9, so that the second sliding block 10 can press and fix the welded pipe, improving the overall stability of the device.

[0035] Specifically, a limit ring 21 is provided at the bottom end of the second threaded rod 11, and the limit ring 21 is rotatably installed inside the second sliding block 10. The advantage is that when turning the handle 12 to drive the second threaded rod 11 to rotate, the second threaded rod 11 also drives the limit ring 21 to rotate inside the second sliding block 10. Therefore, not only can the second sliding block 10 be driven to move inside the second sliding groove 9, but also the limit ring 21 can effectively limit the position of the second threaded rod 11 to prevent it from falling off or other situations, improving the overall stability.

[0036] Specifically, two limit rods 17 are provided, and second limit blocks 22 are fixedly installed on the outer sides of both of the two limit rods 17. The advantage is that when starting the cylinder 15, the output shaft of the cylinder 15 can drive parts such as the baffle 16 and the sawing machine body 18 to move in the vertical direction, so that the welded pipe can be efficiently sawed. At the same time, the two limit rods 17 can further increase the overall stability of the device, and the multiple second limit blocks 22 can effectively limit the moving paths of the limit rods 17 and the baffle 16 and other parts, avoiding situations such as excessive movement, and ensuring the normal operation of the device.

[0037] Specifically, a support 23 is fixedly installed on the top surface of the workbench 6, a hose nozzle 24 is installed inside the support 23, and one end of the hose nozzle 24 away from the workbench 6 is connected to a water delivery device. The advantage is that the water delivery device can be set as parts such as a water pump. The water pump can spray the coolant on the surface of the welded pipe through the hose nozzle 24. Therefore, when sawing the welded pipe, the coolant can quickly reduce the temperature of the cutting blade, reduce the wear degree of the blade, and improve the overall service life of the device.

[0038] During use, by passing the welded pipe to be cut through the two V-shaped grooves 8 and installing it inside, the V-shaped grooves 8 can be applicable to welded pipes of various different diameters. Moreover, the rubber pad 20 can further improve the stability of the installation of the welded pipe and also avoid damaging the outer surface of the welded pipe, improving the overall applicability of the device. After that, rotating the two handles 12 can drive the second threaded rod 11 to rotate. The second threaded rod 11 can then drive the second slider 10 to move inside the second chute 9. The second slider 10 can thus press and fix the welded pipe. At the same time, the limit ring 21 can also effectively limit the position of the second threaded rod 11 to prevent it from falling off or other situations, improving the overall stability. By starting the drive motor 2, the output shaft of the drive motor 2 can drive the first threaded rod 5 to rotate. The first threaded rod 5 can then drive parts such as the first slider 4 to slide inside the first chute 3, and thus can adjust the positions of parts such as the welded pipe to be cut. Therefore, the positioning accuracy of the welded pipe cutting can be efficiently controlled and improved, and the working efficiency can be improved. By starting the cylinder 15, the output shaft of the cylinder 15 can drive parts such as the baffle 16 and the sawing machine body 18 to move in the vertical direction. Therefore, the welded pipe can be efficiently sawed. At the same time, the two limit rods 17 can further increase the overall stability of the device, and the multiple second limit blocks 22 can effectively limit the moving paths of parts such as the limit rods 17 and the baffle 16 to avoid situations such as excessive movement, ensuring the normal operation of the device.
