Description

Technical Field

[0001] This invention relates to steel pipe production technology, specifically to an automated production equipment for spiral steel pipe processing. Background Technology

[0002] Steel pipe is a widely used steel structural component. In the process of producing steel pipe by processing steel strip coils, the steel strip coil needs to be uncoiled, leveled, and milled before being sent to a forming device to be rolled into a circular tube blank with an opening gap. When the tube is rolled into a circular tube blank on the forming equipment, the opening gap needs to be pre-welded before being sent to the welding mechanism for submerged arc precision welding, thus forming a steel pipe. Because the weld is spiral, it is called a spiral steel pipe.

[0003] Chinese invention patent CN116372599A discloses a spiral steel pipe production equipment. This equipment, through a welding machine platform including upper and lower frames and a sliding frame, allows for adjustment of the welding machine's position to accommodate spiral welded steel pipes of different diameters. The upper and lower frames are connected to a reduction motor via fixed pulleys and suspension ropes, ensuring precise position adjustment. The pulleys slide on the frame, enabling stable up-and-down movement of the entire platform. The welding machine is fixed to the upper and lower frames, reducing vibration and preventing swaying. The flux drop position is accurate and controllable. The spiral steel pipe on the steel pipe support is propelled away from the support by a toggle device and rolls on a track. Two deceleration blocks are installed on the track. The steel pipe is significantly decelerated as it rolls over the deceleration blocks, and then further decelerated by a flexible deceleration block, rolling very slowly onto the conveyor wheel. It stops on the conveyor wheel by a stop seat. The motor is then started, driving the conveyor wheel to rotate and transport the steel pipe in a direction perpendicular to the track, thus achieving the turning and transport of the steel pipe.

[0004] When existing equipment winds steel pipes, the unstable tension of the steel strip can cause fluctuations in the steel strip during winding, and may even lead to stretching, breakage or loosening, which in turn affects the uniformity of the outer diameter and wall thickness of the steel pipe. At the same time, the outer diameter of the wound steel pipe may be affected by a variety of factors, resulting in deviations in the outer diameter of the steel pipe. Therefore, an automated production equipment for spiral steel pipe processing has been developed. Summary of the Invention

[0005] The purpose of this invention is to provide an automated production equipment for spiral steel pipe processing to overcome the above-mentioned shortcomings in the prior art.

A snap-fit ​​block is fixedly installed at the end of the gear plate, an arc-shaped plate is fixedly installed at the end of the snap-fit ​​block, and a limiting rod is fixedly installed at the end of the arc-shaped plate.

[0007] As a further optimization of the present invention, a protective plate is fixedly installed at the end of the fixed plate, a locking block is fixedly installed at the end of the protective plate, a threaded rod is rotatably installed on the inner wall of the locking block, a ring is rotatably installed on the outer surface of the threaded rod, and the end of the threaded rod is engaged with the inner wall of the transmission gear.

[0008] As a further optimization of the present invention, multiple sets of locking rods are uniformly and rotatably installed on the outer surface of the locking block, and a connecting plate is rotatably installed at the end of the locking rod, with a connecting groove provided on one side of the connecting plate.

[0009] As a further optimization of the present invention, a movable rod corresponding to the locking rod is rotatably mounted on the outer surface of the ring, the end of the movable rod is slidably connected to the inner wall of the connecting groove, and an adjusting plate is fixedly mounted on the end of the connecting plate.

[0010] As a further optimization of the present invention, the adjustment component includes a base plate that is snapped into the base, a driving member is fixedly installed at the end of the base plate, a driving block is fixedly installed at the output end of the driving member, and driving grooves are symmetrically opened on the outer surface of the driving block.

[0011] As a further optimization of the present invention, a connecting block is fixedly installed on the inner wall of the base plate, and a connecting rod is rotatably installed at the end of the connecting block. A swing block is fixedly installed at one end of the connecting rod, and a movable block is fixedly installed at the other end. The outer surface of the end of the swing block is slidably connected to the inner wall of the drive groove.

[0012] As a further optimization of the present invention, an extension plate is fixedly installed on one side of the base plate, and a through hole is opened at the end of the extension plate. An extension rod is slidably installed on the inner wall of the through hole.

[0013] As a further optimization of the present invention, a guide block is fixedly installed at the lower end of the extension rod, and a guide groove is provided on one side of the guide block.

[0016] Compared with the prior art, the automated production equipment for spiral steel pipe processing provided by the present invention has the following advantages: By adjusting the outer diameter of the steel pipe using protective components, it is possible to flexibly adjust the outer diameter according to different types of steel pipes, effectively preventing the outer diameter from exceeding or not meeting the standard range. At the same time, it is possible to monitor and adjust the outer diameter of the steel pipe in real time during the winding process, ensuring that the inner wall of the steel pipe is always in the best condition.

[0017] By adjusting the tension of the steel strip in real time, the dimensional deviation of the finished steel pipe caused by unstable tension or uneven diameter expansion can be effectively avoided. At the same time, the tension of the steel strip is kept within the ideal range throughout the entire processing, thereby improving the dimensional stability and surface quality of the product.

[0018] Through the synergistic action of the protective and adjusting components, the tension and outer diameter can be adjusted synchronously to ensure uniform tension of the steel strip. Precise tension adjustment effectively prevents the steel strip from stretching and unevenly winding. At the same time, when adjusting the outer diameter of the steel pipe, local deformation of the steel pipe is avoided, thereby significantly reducing quality defects caused by uneven tension or unstable outer diameter and improving the overall quality of the steel pipe.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] Example: Please refer to Figures 1-8 An automated production equipment for spiral steel pipe processing includes a base 1, a support column 11 fixedly installed at the end of the base 1, a transmission component 12 snapped into the end of the support column 11, and a pallet 13 snapped into one side of the support column 11.

[0025] In this scheme, the end of the support column 11 is equipped with a telescopic device such as an electric telescopic rod, which is connected to an external control device and drives the transmission component 12 to rotate. The transmission component 12 is a device with power output such as a motor, which, together with the inclined transmission roller, drives the spiral steel pipe to rotate and move.

[0026] The ends of the tray 13 are equipped with bolts and other fixing components. By splicing multiple trays 13 together, the needs of different lengths can be met.

[0027] Furthermore, the protective component 2, which is assembled at the end of the base 1, adjusts the outer diameter of the spiral steel pipe. The protective component 2 includes a fixing plate 21 that engages with the base 1. A support block 22 is fixedly mounted at the end of the fixing plate 21, and a positioning plate 23 is fixedly mounted at the upper end of the support block 22. Positioning grooves 231 are symmetrically formed at the ends of the positioning plate 23. A transmission gear 24 is rotatably mounted at the middle position of the end of the positioning plate 23.

[0028] Specifically, the end of the positioning plate 23 is equipped with a power output device such as a motor and is connected to an external control device. At the same time, the output end of the motor is fixedly connected to the end of the transmission gear 24, thereby driving the transmission gear 24 to rotate.

[0029] Furthermore, a gear plate 25 is slidably installed on the inner wall of the positioning groove 231, and the outer surface of the gear plate 25 meshes with the outer surface of the transmission gear 24.

[0030] Specifically, since the outer surface of the gear plate 25 meshes with the outer surface of the transmission gear 24, the symmetrically arranged gear plate 25 moves in the opposite direction when the transmission gear 24 rotates.

[0031] Furthermore, a snap-fit ​​block 26 is fixedly installed at the end of the gear plate 25, an arc-shaped plate 261 is fixedly installed at the end of the snap-fit ​​block 26, and a limiting rod 262 is fixedly installed at the end of the arc-shaped plate 261.

[0032] Specifically, when the gear plate 25 moves, it drives the arc-shaped plate 261 fixedly installed at its end to move, thereby limiting the steel strip and causing the steel strip to move along the inner wall of the arc-shaped plate 261 to form a tubular shape. This is coordinated with the limiting rod 262, which is fixedly installed to limit and support the steel strip.

[0033] Furthermore, a protective plate 211 is fixedly installed at the end of the fixed plate 21, a locking block 28 is fixedly installed at the end of the protective plate 211, a threaded rod 272 is rotatably installed on the inner wall of the locking block 28, a ring 27 is threaded on the outer surface of the threaded rod 272, and the end of the threaded rod 272 is engaged with the inner wall of the transmission gear 24.

[0034] Specifically, the locking block 28 is supported by the protective plate 211, and the threaded rod 272 is also supported. The end of the threaded rod 272 is provided with a protrusion, and the outer surface of the protrusion engages with the inner wall of the transmission gear 24, so that when the transmission gear 24 rotates, it drives the threaded rod 272 to rotate. At the same time, when the threaded rod 272 rotates, it drives the ring 27 rotatably mounted on its outer surface to move.

[0035] Furthermore, multiple sets of locking rods 281 are uniformly rotatably mounted on the outer surface of the locking block 28, and a connecting plate 282 is rotatably mounted on the end of the locking rod 281. A connecting groove 283 is provided on one side of the connecting plate 282.

[0036] Specifically, the locking rod 281 is supported by the locking block 28 and moves in conjunction with the connecting plate 282 rotatably mounted at its end. At the same time, the movable rod 271 is limited by the connecting groove 283, so that the movable rod 271 moves along the inner wall of the connecting groove 283 when it moves.

[0037] Furthermore, a movable rod 271 corresponding to the locking rod 281 is rotatably mounted on the outer surface of the ring 27. The end of the movable rod 271 is slidably connected to the inner wall of the connecting groove 283, while an adjusting plate 29 is fixedly mounted on the end of the connecting plate 282.

[0038] Specifically, when the threaded rod 272 rotates, it drives the ring 27 rotatably mounted on its outer surface to move, which in turn drives the movable rod 271 rotatably mounted on its outer surface to move simultaneously. The middle position of the outer surface of the movable rod 271 is rotatably connected to the middle position of the outer surface of the locking rod 281, so that when the movable rod 271 moves, it drives the movable rod 271 to move around the connection point with the locking rod 281, simultaneously driving the adjusting plate 29 fixedly mounted at its end to move and supporting the inner wall of the steel pipe. A detection device, which is an existing diameter detection device, is provided on one side of the adjusting plate 29 for detecting the inner wall of the steel pipe.

[0039] Furthermore, the adjustment component 3 is assembled at the end of the base 1 and located on one side of the protective component 2. The tension of the steel belt during conveying is adjusted by the adjustment component 3. The adjustment component 3 includes a base plate 31 that is snapped into the base 1. A driving component 32 is fixedly installed at the end of the base plate 31. A driving block 33 is fixedly installed at the output end of the driving component 32. The outer surface of the driving block 33 is symmetrically provided with driving grooves 331.

[0040] In this embodiment, the driving component 32 is a device with power output such as a motor, and is connected to an external control device. When the driving component 32 is started, it drives the driving block 33 fixedly installed at its output end to rotate, thereby driving the driving groove 331 opened on its outer surface to rotate; the driving groove 331 is Z-shaped when unfolded.

[0041] Furthermore, a connecting block 35 is fixedly installed on the inner wall of the base plate 31, and a connecting rod 351 is rotatably installed at the end of the connecting block 35. A swing block 36 is fixedly installed at one end of the connecting rod 351, and a movable block 37 is fixedly installed at the other end.

[0042] Specifically, the connecting rod 351 is supported by the connecting block 35, and when the swing block 36 moves, it drives the entire connecting rod 351 to rotate around the connecting block 35, thereby driving the movable block 37 fixedly installed at the other end of the connecting rod 351 to rotate.

[0043] Furthermore, the outer surface of the end of the swing block 36 is slidably connected to the inner wall of the drive groove 331.

[0044] Specifically, when the drive block 33 rotates, it drives the drive groove 331 to rotate. Since the outer surface of the swing block 36 is slidably connected to the inner wall of the drive groove 331, the swing block 36 moves when the drive block 33 rotates.

[0045] Furthermore, an extension plate 34 is fixedly installed on one side of the base plate 31, and a through hole 341 is opened at the end of the extension plate 34. An extension rod 382 is slidably installed on the inner wall of the through hole 341.

[0046] Specifically, the extension rod 382 is supported by the through hole 341 on the extension plate 34, and moves up and down along the inner wall of the through hole 341 when the extension rod 382 moves.

[0047] Furthermore, a guide block 38 is fixedly installed at the lower end of the extension rod 382, ​​and a guide groove 381 is provided on one side of the guide block 38. The inner wall of the guide groove 381 is slidably connected to the outer surface of the end of the movable block 37.

[0048] Specifically, the inner wall of the guide groove 381 is slidably connected to the outer surface of the end of the movable block 37, so that when the movable block 37 moves, it drives the guide block 38 to move, and at the same time drives the extension rod 382 to move up and down.

[0049] Furthermore, a docking plate 39 is fixedly installed on the upper end of the extension rod 382, ​​and a telescopic rod 391 is symmetrically fixedly installed on the upper end of the docking plate 39. A roller 392 is fixedly installed on the upper end of the telescopic rod 391.

[0050] Specifically, when the extension rod 382 moves, it drives the docking plate 39 to move. The telescopic rod 391 is an electric telescopic rod or other equipment with telescopic function and is connected to an external control device. When the telescopic rod 391 moves, it drives the roller 392 fixedly installed at its end to move, thereby supporting the steel strip.

[0051] A limiting plate 311 is provided on one side of the base plate 31, and one side of the limiting plate 311 is slidably connected to the outer surface of the docking plate 39, thereby making the docking plate 39 remain stable as a whole when it moves.

[0052] Furthermore, a pressing block 393 is rotatably mounted on one side of the docking plate 39. One end of the pressing block 393 rotates with the end of the roller 392, and the other end is rotatably connected to the upper end of the docking plate 39.

[0053] Specifically, both ends of the pressing block 393 are provided with elastic elements, which are rotatably connected to the ends of the docking plate 39 and the roller 392, respectively. Together with the telescopic rod 391, the tension of the steel belt is adjusted so that the steel belt is in the best condition when it is conveyed to the winding position.

[0054] The control device can choose a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.

[0055] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
