Description

Technical Field

[0001] This invention relates to the field of high-frequency welded pipe processing equipment, specifically to an integrated online straightening and cutting processing device for high-frequency welded pipes. Background Technology

[0002] High-frequency welded pipe, as an important type of metal pipe, is widely used in many fields such as petroleum, chemical, construction, and machinery manufacturing due to its advantages of high production efficiency, low cost, and stable performance. During the production process of high-frequency welded pipe, due to factors such as welding stress and rolling processes, the pipe is prone to bending and deformation, which not only affects the accuracy of subsequent processing and assembly but may also reduce the structural strength and service life of the pipe. Therefore, the straightening process becomes a crucial step in ensuring the quality of high-frequency welded pipe.

[0003] Currently, most high-frequency welded pipe straightening equipment on the market adopts a unidirectional extrusion straightening method. This involves applying pressure to the welded pipe using straightening rollers symmetrically arranged vertically or horizontally, forcibly straightening the bent parts of the pipe. However, this traditional straightening method has significant drawbacks: firstly, the clamping stability of the welded pipe during straightening is poor, especially for large-diameter or thin-walled welded pipes, where uneven clamping force can easily lead to secondary deformation or even localized dents; secondly, simple extrusion cannot completely eliminate residual stress inside the welded pipe, resulting in springback after straightening, leading to insufficient straightening accuracy and requiring multiple rework adjustments, severely impacting production efficiency.

[0004] Meanwhile, in the existing high-frequency welded pipe processing flow, straightening and cutting are mostly independent processes. After straightening, the welded pipe needs to be transported to the cutting station manually or with additional conveying equipment. This not only increases production steps and labor costs, but also may cause the pipe to deform again due to collisions and vibrations during transportation, affecting the final product quality. In addition, traditional cutting equipment is prone to uneven cuts and pipe shaking during the cutting process due to the lack of stable support and positioning mechanisms, further reducing processing accuracy.

[0005] Furthermore, traditional straightening equipment lacks flexibility in pressure adjustment for high-frequency welded pipes of different specifications and hardness, often requiring the replacement of different straightening dies or complex mechanical adjustments, resulting in poor adaptability and difficulty in meeting diverse production needs. Moreover, most straightening equipment lacks heating auxiliary devices, making straightening difficult and energy-intensive for rigid high-alloy welded pipes, and easily causing scratches on the pipe surface. Summary of the Invention

[0012] Preferably, both the lower surface of the upper straightening seat and the upper surface of the lower straightening seat are provided with anti-slip layers, and a heating component is installed inside the lower straightening seat.

[0015] This invention provides an integrated online straightening and cutting processing device for high-frequency welded pipes. It has the following beneficial effects:

[0016] 1. This invention employs a double-walled clamping structure. The inner wall, driven by a telescopic cylinder, expands outward to contact the pipe wall, while the outer wall, aided by the vortex-like spiral groove of a rotating disc, causes the outer wall clamping seat to tighten inward simultaneously. This bidirectional clamping significantly improves the stability of the welded pipe, preventing displacement or shaking during processing. Simultaneously, the clamping forces are evenly transmitted through the mechanical structure, avoiding the problem of welded pipe deformation caused by excessive clamping force in one direction, thus ensuring the original shape accuracy of the welded pipe.

[0017] 2. This invention achieves "kneading" straightening through the cooperation of an upper and lower straightening seat. The lower straightening seat is driven by a reciprocating cylinder to rotate the welded pipe. Combined with the continuous pressure from the upper straightening seat, this method more comprehensively eliminates bending stress in the welded pipe compared to traditional extrusion straightening. The heating component heats the bent areas, reducing the rigidity of the welded pipe and minimizing springback after straightening, further improving straightening accuracy. Furthermore, the elastic pressure structure composed of the spring plate and the rotating frame applies pressure evenly through the reverse elastic force, and the sliding compensation of the pressure rollers ensures stable pressure throughout the process, avoiding surface deformation caused by pressure fluctuations and resulting in a more uniform straightening effect.

[0018] 3. This invention uses a bidirectional cylinder to drive the support platform to change the position of the spring plate support point, thereby adjusting the pressure applied by the upper straightening seat. This adapts to the straightening needs of welded pipes with different hardness and specifications, expanding the applicability of the device. Simultaneously, the design of the internal hexagonal adjusting nut allows operators to quickly adjust the position of the outer wall clamping seat according to the diameter of the welded pipe, making operation convenient and efficient.

[0029] The technical solutions in 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example:

[0031] Please see the appendix Figure 1 - Appendix Figure 9 This invention provides an integrated online straightening and cutting device for high-frequency welded pipes, such as... Figure 1 As shown, the device includes a worktable 1, which serves as the basic load-bearing structure for the entire device, providing a stable mounting platform for each component and ensuring the overall stability of the device during processing. A linear motion module 2 is fixedly mounted on one side of the top of the worktable 1. The linear motion module 2 provides precise linear drive power, enabling the connected components to move smoothly back and forth. A slide table 3 is mounted on the drive end of the linear motion module 2. Driven by the linear motion module 2, the slide table 3 can move along a set trajectory, thereby driving the components mounted above to move synchronously. A mounting base 4 is fixedly mounted on the top of the slide table 3. The mounting base 4 is used to support components such as the rotating body 5, serving a connecting and fixing function. The rotating body 5 is movably mounted on one side of the mounting base 4. The rotating body 5 can rotate relative to the mounting base 4, which facilitates the adjustment of the clamping angle of the welded pipe. A rotating disk 6 is movably installed inside the rotating body 5. The rotating disk 6 can rotate flexibly inside the rotating body 5, and its rotation can drive related components to achieve coordinated action. A fixed cylinder 7 is fixedly installed in the middle of the rotating body 5. The fixed cylinder 7 provides guidance and initial positioning for the insertion of the welded pipe, ensuring that the welded pipe can accurately enter the clamping area. Three guide rods 8 are fixedly installed on the inner side wall of the rotating body 5. The guide rods 8 guide and limit the movement of the inner wall clamping seat, ensuring the accuracy of its movement trajectory. An outer wall clamping seat 9 is movably installed on the outer diameter of each guide rod 8. The outer wall clamping seat 9 can slide along the guide rod 8 and is used to clamp and fix the welded pipe from the outside.

[0032] A first gantry frame 20 is fixedly installed at the top center of the workbench 1. The first gantry frame 20 provides installation support for components such as the control room 22, forming a stable portal frame structure. The control room 22 is movably installed on the upper side of the interior of the first gantry frame 20. The control room 22 contains straightening-related control and transmission components and can move up and down within the first gantry frame 20. A first hydraulic cylinder 21 is fixedly installed at the top of the first gantry frame 20, and the drive end of the first hydraulic cylinder 21 is fixedly installed at the top of the control room 22. The first hydraulic cylinder 21 can lift... A powerful driving force is provided to drive the control room 22 to move up and down, thereby controlling the position of the upper straightening seat 23. The upper straightening seat 23 is located below the control room 22. The upper straightening seat 23 and the lower straightening seat 24 cooperate to straighten the welded pipe. The lower straightening seat 24 is movably installed on the upper surface of the workbench 1 near the lower position of the upper straightening seat 23 via a guide rail. The lower straightening seat 24 can slide along the guide rail and achieve reciprocating motion under the drive of the reciprocating cylinder 25, which works with the upper straightening seat 23 to complete the "rubbing" straightening of the welded pipe.

[0033] A reciprocating cylinder 25 is fixedly installed on the upper surface of the workbench 1 near the lower straightening seat 24, and the drive end of the reciprocating cylinder 25 is fixedly installed on one side of the lower straightening seat 24. The reciprocating cylinder 25 can provide reciprocating driving force, driving the lower straightening seat 24 to reciprocate, thereby driving the welded pipe to rotate. A crossbeam 26 is fixedly installed in the middle of the control chamber 22. The crossbeam 26 provides the mounting base for components such as the rotating frame 27, and plays a supporting and connecting role. Rotating frames 27 are movably installed at both ends of the crossbeam 26. The rotating frames 27 can rotate around the ends of the crossbeam 26 and bend under force, thereby driving the related components to move. Two spring plates 28 are fixedly installed on both sides of the interior of the crossbeam 26, and the ends of the spring plates 28 extend into the interior of the corresponding rotating frame 27. The spring plates 28 have good elasticity and large elastic force. When the rotating frame 27 bends, it will bend and generate elastic force. To provide pressure to the upper straightening seat 23, pressure rollers 38 are fixedly installed on the inner side of the bottom wall of the rotating frame 27, and the ends of the pressure rollers 38 abut against the lower surface of the corresponding side spring plate 28. The pressure rollers bend the spring plate 28 to generate elastic force. At the same time, the pressure rollers 38 slide on the surface of the spring plate 28 during the bending process to compensate for the increasing elastic force as the spring plate 28 bends. The bottom end of the rotating frame 27 is movably installed with a connecting plate 29, which plays a role in force transmission. It can transmit the movement of the rotating frame 27 to the pressure plate 30. The end of the connecting plate 29 is movably installed with a pressure plate 30, which can transmit the force transmitted by the connecting plate 29 to the upper straightening seat 23, thereby driving the upper straightening seat 23 to move. The bottom end of the pressure plate 30 extends to the outside of the control chamber 22 and is fixedly installed on the top of the upper straightening seat 23, thereby realizing the linkage between the internal components of the control chamber 22 and the upper straightening seat 23.

[0034] In this embodiment, a spiral groove 10 is formed on the outer end surface of the rotating disk 6. The shape design of the spiral groove 10 allows the slider 11 to move along the groove trajectory when the rotating disk 6 rotates, thereby realizing the synchronous movement of the outer wall clamping seat 9. The inner end of the outer wall clamping seat 9 is fixedly installed with sliders 11, and the ends of the sliders 11 are movably disposed inside the spiral groove 10. The sliders 11 slide in the spiral groove 10, converting the rotational motion of the rotating disk 6 into the linear motion of the outer wall clamping seat 9. A driven bevel tooth is fixedly installed on the inner end of the rotating disk 6. Wheel 12, driven bevel gear 12 meshes with bevel gear 14, which can transmit the rotational motion of bevel gear 14 to rotating disk 6. An internal hexagonal adjusting nut 13 is movably installed on one side of rotating body 5. The internal hexagonal adjusting nut 13 makes it easy for the operator to use an internal hexagonal wrench to rotate, thereby driving bevel gear 14 to rotate. The bevel gear 14 is fixedly installed on the inner side of the internal hexagonal adjusting nut 13 and meshes with the inner end of driven bevel gear 12. When bevel gear 14 rotates, it can drive driven bevel gear 12 to rotate, realizing the transmission of power and the change of direction.

[0035] Furthermore, a movable cylinder 15 is movably installed on the inner and outer sides of the fixed cylinder 7. The movable cylinder 15 can move inside the fixed cylinder 7, and its movement drives the second cross rod 17 to move. Several first cross rods 16 are movably installed on the outer wall of the fixed cylinder 7. The first cross rods 16 and the second cross rods 17 cooperate with each other to support the inner support plate 18. Several second cross rods 17 are movably installed on the outer wall of the movable cylinder 15. The second cross rods 17 can change angle under the drive of the movable cylinder 15, thereby pushing the inner support plate 18 to move. The outer ends of the corresponding first cross rods 16 and second cross rods 17 are fixedly installed on the inner end of the inner support plate 18. The inner support plate 18 can expand outward under the drive of the first cross rods 16 and second cross rods 17 to clamp from inside the welded pipe. A telescopic cylinder 19 is fixedly installed on the inner side of the fixed cylinder 7, and the driving end of the telescopic cylinder 19 is fixedly installed on one end of the movable cylinder 15. The telescopic cylinder 19 can provide telescopic driving force to drive the movable cylinder 15 to move axially, thereby controlling the expansion and contraction of the inner support plate 18.

[0036] Furthermore, both the lower surface of the upper straightening seat 23 and the upper surface of the lower straightening seat 24 are provided with anti-slip layers. The anti-slip layers can increase the friction with the surface of the welded pipe, prevent the welded pipe from slipping during the straightening process, and ensure the stable progress of the straightening work. The lower straightening seat 24 is equipped with a heating component. The heating component heats the bent part of the welded pipe during straightening, reduces the rigidity of the welded pipe, reduces the springback phenomenon after straightening, and improves the straightening effect.

[0037] Furthermore, both sides of the crossbeam 26 are fixedly installed with guide rods 31. The guide rods 31 provide guidance for the movement of the support platform 32, ensuring that the support platform 32 can move smoothly along a straight line. The support platform 32 is movably installed on the outer diameter of the guide rod 31, and both ends of the support platform 32 abut against the upper surface of the corresponding side spring plate 28. The support platform 32 can slide on the guide rod 31. The change of its position can adjust the support point of the spring plate 28, thereby changing the elastic force when the spring plate 28 bends. A two-way cylinder 33 is fixedly installed in the middle of the bottom end of the crossbeam 26. The two-way cylinder 33 can provide two-way driving force, driving the support platforms 32 on both sides to move inward or outward synchronously. The two driving ends of the two-way cylinder 33 are respectively fixedly installed at the bottom end of the corresponding side support platform 32, thereby realizing precise control of the position of the support platform 32.

[0038] Furthermore, a second gantry frame 34 is fixedly installed on the other side of the top of the workbench 1. The second gantry frame 34 provides mounting support for the second hydraulic cylinder 35 and the saw blade cutter 36, forming a frame structure for the cutting operation. The second hydraulic cylinder 35 is fixedly installed at the top of the second gantry frame 34. The second hydraulic cylinder 35 can provide strong driving force to drive the saw blade cutter 36 to move up and down, thereby cutting the welded pipe. The driving end of the second hydraulic cylinder 35 extends into the interior of the second gantry frame 34 and is fixedly installed with the saw blade cutter 36. The saw blade cutter 36 can rotate at high speed to cut the welded pipe that moves below it. A support platform 37 is fixedly installed on the upper surface of the workbench 1 near the lower part of the saw blade cutter 36. The support platform 37 provides support for the welded pipe during the cutting process, ensuring the stability of the welded pipe during cutting and ensuring the flatness of the cut surface.

[0039] Working principle: One end of the high-frequency welded pipe to be straightened is placed inside the rotating frame 27, and the part of the pipe to be straightened rests on the surface of the lower straightening seat 24. Then, the telescopic cylinder 19 is activated, which controls the movement of the internal piston rod, driving the movable cylinder 15 to move. When the movable cylinder 15 moves, it will drive one end of the second cross rod 17 to move as well. In conjunction with the first cross rod 16, it will drive all the inner support plates 18 to move outward, so that all the inner support plates 18 abut against the inner wall of the welded pipe, clamping and fixing the welded pipe from the inside. Then, the operator uses an Allen wrench to rotate the Allen adjusting nut 13, which drives the bevel gear 14 to rotate. The bevel gear 14 will drive the driven bevel gear 12 to rotate, thereby driving the rotating disk 6 to rotate. When the rotating disk 6 rotates, it will drive the vortex spiral on the surface. The rotation of groove 10 causes all sliders 11 to move inside the spiral groove 10. Then, using the limiting effect of guide rod 8, all outer wall clamping seats 9 move inward synchronously, causing them to abut and clamp against the outer wall of the welded pipe. This achieves double-wall clamping of the welded pipe, significantly improving clamping stability and preventing deformation due to excessive clamping force. Subsequently, the first hydraulic cylinder 21 drives the control chamber 22 to descend, causing the upper straightening seat 23 to descend as well. When the upper straightening seat 23 contacts the welded pipe, the control chamber 22 continues to descend. At this point, the welded pipe will press against the upper straightening seat 23, causing it to rise. As the upper straightening seat 23 rises, it causes the pressure plate 30 to rise, and through the connecting plate 29, it causes the rotating frame 27 to bend. During bending, the pressure roller 38 drives the spring plate 28 to bend and generate elasticity. The reverse action of this elasticity applies pressure to the welded pipe. Then, the heating component inside the lower straightening seat 24 is activated to heat the bent area, reducing the rigidity of the welded pipe and minimizing springback during straightening. After completion, the reciprocating cylinder 25 is activated, driving the lower straightening seat 24 to reciprocate, causing the welded pipe to rotate on the surface of the lower straightening seat 24. Combined with the continuous pressure applied above the welded pipe by the upper straightening seat 23, this achieves a "kneading" straightening process. Compared to traditional extrusion straightening, this method offers higher straightening quality and efficiency. Furthermore, during bending, the pressure roller 38 slides outward relative to the spring plate 28, compensating for... The increasing elastic force as the spring plate 28 bends ensures that the reaction force applied by the spring plate 28 remains uniform throughout the process. This, in turn, maintains uniform pressure applied to the welded pipe by the upper straightening seat 23, preventing excessive pressure that could deform the welded pipe surface. Furthermore, the bidirectional cylinder 33 can drive the support platforms 32 on both sides to move synchronously inward or outward. By changing the position of the support platforms 32, the support point position of the spring plate 28 during bending is altered. When the support point position changes, the elastic force generated during bending also changes, thereby altering the pressure applied to the welded pipe by the upper straightening seat 23. This facilitates straightening of welded pipes with different hardness. After straightening is complete, the linear motion module 2 is activated, controlling the movement of the slide table 3 to move the welded pipe.The welded pipe is moved to a position below the second gantry 34, with its lower surface resting on the platform 37. At this point, the second hydraulic cylinder 35 is activated, causing the saw blade cutting machine 36 to descend and cut the welded pipe.
