[0013] As an optional solution of the irregular structure tank forming equipment of the present invention, wherein: a support plate is installed at the end away from the hollow plate, a detector is pinned to the support, and a torsion spring is provided between the detector and the support.

[0014] As an optional solution of the irregular structure tank forming equipment of the present invention, wherein: a mounting frame is provided below the support plate, the gear is rotatably installed in the mounting frame, and a second motor is installed on one side of one set of the gears, and the second motor is installed on the outer wall of the mounting frame.

[0015] As an optional solution of the irregular structure tank forming equipment of the present invention, wherein: an extension plate is connected to one side of the mounting frame, a corrugated plate is provided on the second guide rail and located on the rack side, a second guide rod is connected to the bottom of the support plate, the second guide rod is slidably installed in the extension plate, a second spring is connected between the support plate and the extension plate, the second spring is sleeved on the outer wall of the second guide rod, and the bottom end of the second guide rod is fitted with the corrugated plate.

[0016] The present invention has the following beneficial effects: 1. This irregularly shaped tank forming equipment achieves automated cleaning of welding slag from the inner wall of the tank through the coordinated operation of a slag removal component and a moving component. The suction frame reciprocates along the second guide rail under the meshing transmission of gears and racks, while the first motor drives the moving wheel to move the entire slag removal component longitudinally along the third guide rail, allowing the suction nozzle to cover the entire curved surface area of ​​the tank's inner wall. The suction nozzle is matched to the curve of the tank's inner wall, and with the elastic buffering effect of the first spring, it ensures that the suction nozzle always fits against the tank wall and maintains a stable suction gap, effectively improving the efficiency of welding slag collection.

[0017] 2. This irregularly shaped tank forming equipment, through the combination design of a universal ball joint and an electric slide table in the support assembly, allows the second guide rail to flexibly adjust its angle and position in three-dimensional space to adapt to irregularly shaped tank structures with different curvatures. When the tank cross-section changes, the electric slide table drives the second guide rail to extend and retract, while the universal ball joint provides multi-directional rotational freedom, ensuring that the suction frame is always in the optimal working posture; 3. This irregularly shaped tank forming equipment, through the fitting design of the corrugated plate and the second guide rod, enables the support plate to move up and down periodically. During the gear transmission process, the second guide rod undulates up and down along the contour of the corrugated plate, causing the support plate and the suction frame above to vibrate slightly, increasing the suction space of the suction frame, thereby expanding the effective coverage of the suction nozzle. This vibration effect causes the fine welding slag particles attached to the edge of the suction nozzle to detach from the adhesive state, while promoting the turbulent mixing of the airflow in the suction pipe, preventing welding slag from depositing and clogging at the pipe bend.

[0018] 4. This irregularly shaped tank forming equipment uses a gear transmission mechanism driven by a second motor to form a dual-axis linkage control with the moving wheel driven by a first motor. By adjusting the speed ratio of the two motors, various operating modes can be achieved, such as spiral trajectory scanning of the suction nozzle on the inner wall of the tank or fixed-point reciprocating cleaning. The negative pressure airflow generated by the suction fan is transported to the suction frame through the suction pipe, and finally the welding slag is collected by the suction nozzle, realizing automatic welding slag recovery.

[0028] 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. 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.

[0029] Example 1, please refer to Figures 1 to 8 This invention discloses an irregularly shaped tank forming equipment, including a first gantry frame 1 and a second gantry frame 2 connected below the first gantry frame 1. A ladder 3 is provided on one side of the first gantry frame 1 and the second gantry frame 2. Two sets of first guide rails 4 are symmetrically arranged at the bottom of the second gantry frame 2. A bracket 6 is provided on the first guide rail 4. Two sets of third guide rails 38 are symmetrically arranged between the two sets of first guide rails 4. A movable frame 5 is provided on the third guide rail 38. The bracket 6 is installed on the movable frame 5. A support roller 7 is rotatably installed inside the bracket 6.

[0030] In this embodiment, a first gantry frame 1 and a second gantry frame 2 are sequentially arranged. The gantry-type main body can be equipped with welding devices such as fully automatic welding guns, and the movable support 6 supports the tank body, adapting to tanks of different sizes. In specific use, the irregularly shaped tank to be formed is placed on the support roller 7, and the rotation of the support roller 7 drives the tank body to rotate, facilitating circumferential welding operations on the tank body. The arrangement of the first guide rail 4 and the third guide rail 38 allows the support 6 and the movable frame 5 to be adaptively adjusted according to the length and diameter of the tank body, improving the versatility and flexibility of the equipment.

[0031] Example 2 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 8It also includes a slag removal assembly set on two sets of third guide rails 38. The slag removal assembly includes a suction box 9 and a suction frame 20 connected to one side of the suction box 9. A suction fan 10 is installed on one side of the suction box 9, and a suction pipe 21 is connected to one side of the suction box 9. The suction frame 20 is connected to the suction box 9 through the suction pipe 21. A suction nozzle 27 is connected to one side of the suction frame 20. The suction nozzle 27 is set to match the curve of the inner wall of the tank.

[0032] In this embodiment, by setting up a slag removal component, welding slag is collected and processed in real time during the welding process, effectively solving the problem of welding slag residue affecting welding quality and subsequent cleaning difficulties. After the suction fan 10 is started, it generates negative pressure, which is transmitted to the suction frame 20 through the suction pipe 21, and finally the suction nozzle 27 draws and collects the welding slag around the weld.

[0033] Specifically, the suction nozzle 27 is designed to match the curved contour of the inner wall of the irregularly shaped tank, ensuring that the suction nozzle 27 maintains an appropriate contact distance with the inner wall of the tank. This ensures efficient suction of welding slag while avoiding mechanical interference with the tank wall. The suction box 9 centrally stores the collected welding slag for subsequent unified processing, enabling simultaneous welding and slag removal, and significantly shortening the production cycle.

[0034] Example 3 is an explanation based on Example 2. For details, please refer to [link / reference]. Figures 1 to 8 The bottom of the suction box 9 is equipped with a base plate 8, and the bottom of the base plate 8 is provided with four sets of moving wheels 19. The moving wheels 19 are slidably connected to the third guide rail 38. The two sets of moving wheels 19 are connected to a drive shaft 17, and the drive shaft 17 is connected to a first motor 18.

[0035] In this embodiment, the first motor 18 drives the drive shaft 17 to rotate, which in turn drives the moving wheel 19 to reciprocate on the third guide rail 38, thereby achieving automatic displacement of the slag removal component along the axial direction of the tank. The third guide rail 38 is arranged parallel to the first guide rail 4 to ensure that the movement trajectory of the slag removal component is consistent with the axis of the tank, so that the suction nozzle 27 can cover the entire welding area of ​​the tank.

[0036] Specifically, the moving wheel 19 and the I-shaped cross-section of the third guide rail 38 form a stable fit to prevent the slag removal assembly from shifting or overturning during movement, thus ensuring the continuity and stability of the slag removal operation.

[0037] Example 4 is an explanation based on Example 2. For details, please refer to [link / reference]. Figures 1 to 8The bottom of the suction frame 20 is provided with a movable component, which includes two sets of second guide rails 11. A rack 13 is installed on the second guide rails 11, and a gear 14 meshes on the rack 13. A mounting frame 15 is provided below the support plate 16. The gear 14 is rotatably installed in the mounting frame 15. A second motor 26 is installed on one side of one set of gears 14. The second motor 26 is installed on the outer wall of the mounting frame 15.

[0038] In this embodiment, the second motor 26 drives the gear 14 to rotate, and the meshing transmission between the gear 14 and the rack 13 drives the mounting frame 15 and the support plate 16 above it to move back and forth along the second guide rail 11, thereby realizing the automatic adjustment of the suction frame 20 along the radial direction of the tank.

[0039] Specifically, the second guide rail 11 adopts a rectangular cross-section structure, which matches the guide groove at the bottom of the mounting bracket 15, effectively limiting the lateral sway of the support plate 16 during movement and ensuring that the suction nozzle 27 maintains a constant working distance from the tank surface. The rack 13 is fixed to the inner side of the second guide rail 11 by countersunk bolts, and the gear 14 adopts a helical cylindrical gear structure with a large meshing overlap, smooth transmission and strong load-bearing capacity, which can adapt to the vibration conditions in slag removal operations.

[0040] Furthermore, the second motor 26 is a servo motor configuration, which, in conjunction with encoder feedback, enables precise positioning of the suction frame 20, achieving a positioning accuracy of ±0.5mm, meeting the adaptive adjustment requirements for welding positions of tanks of different specifications. When it is necessary to switch tank models, the control system automatically calculates the target stroke of the rack 13 according to preset parameters, driving the suction nozzle 27 to quickly reach the optimal slag removal height, significantly improving the equipment's changeover efficiency and process adaptability.

[0041] Example 5 is an explanation based on Example 2. For details, please refer to [link / reference]. Figures 1 to 8 The moving component also includes two sets of support plates 16 and hollow plates 32, which are slidably connected. The suction frame 20 and the hollow plates 32 are elastically connected. The bottom surface of the suction frame 20 is provided with a mounting plate 28, and the bottom of the mounting plate 28 is provided with a first guide rod 29. A ball head 30 is installed at the bottom end of the first guide rod 29. The first guide rod 29 and the hollow plates 32 are slidably connected. A first spring 31 is connected between the mounting plate 28 and the hollow plates 32, and the first spring 31 is sleeved on the outer surface of the first guide rod 29.

[0042] In this embodiment, a linear bearing that mates with the first guide rod 29 is installed inside the hollow plate 32 to reduce sliding friction resistance. Meanwhile, the ball head 30 adopts a universal ball structure, allowing the suction frame 20 to adaptively adjust its angle according to the curvature of the tank surface, ensuring that the end face of the suction nozzle 27 fits the weld area. The first spring 31 is a compression spring with an optimized stiffness coefficient. It provides sufficient preload to keep the suction nozzle 27 close to the tank surface, while also providing elastic relief when encountering local protrusions or weld slag accumulation, preventing rigid collisions that could damage the equipment or scratch the tank surface.

[0043] Two sets of support plates 16 are symmetrically arranged above two sets of mounting brackets 15, forming a stable portal frame structure that effectively distributes the load on the suction frame 20 and the dust removal system. The hollow plate 32 is made of aluminum alloy profile, and its internal cavity structure significantly reduces the overall weight while ensuring structural strength, thus reducing the driving load on the second motor 26. The sliding mating surfaces of the support plate 16 and the hollow plate 32 are precision machined, with a surface roughness controlled below Ra1.6, and the mating clearance is designed to be 0.05mm to 0.1mm, ensuring smooth sliding while suppressing the transmission of micro-vibrations during suction operation.

[0044] When the suction nozzle 27 moves axially along the tank body to remove slag, the elastic compensation function of the first spring 31 can respond in real time to minute changes in the tank diameter or ellipticity errors, ensuring that the suction nozzle 27 maintains a stable contact pressure with the tank surface. This elastic connection structure organically combines rigid positioning with flexible following, inheriting the high-precision positioning advantages of the servo drive system while improving the equipment's adaptability to the surface shape of irregularly shaped tanks through a mechanical adaptive mechanism. It is particularly suitable for slag removal operations on irregularly shaped tanks with non-circular generatrices during welding.

[0045] Example 6 is an explanation based on Example 2. For details, please refer to [link / reference]. Figures 1 to 8 The suction frame 20 is connected to the gear 14 via a support assembly. The support assembly includes clamping blocks 22 symmetrically installed on one side of the base plate 8. A universal ball joint 23 is provided on one side of the clamping block 22. A connecting block 24 is connected to one end of the universal ball joint 23. An electric slide table 25 is provided on one side of the connecting block 24. One end of the second guide rail 11 is connected to the electric slide table 25.

[0046] In this embodiment, the slide seat of the electric slide table 25 is rigidly connected to the connecting block 24, and its driving direction is perpendicular to the extension direction of the second guide rail 11, thereby constructing an orthogonal kinematic pair in a two-dimensional plane. The ball joint structure of the universal ball linkage 23 allows the suction frame 20 to be adjusted for pitch and yaw within a limited angle range. The clearance between the ball head and the ball socket is controlled within 0.02mm, which ensures flexible rotation and avoids position drift during slag removal operations.

[0047] Specifically, the clamping block 22 and the base plate 8 adopt an adjustable mounting structure. When the gear 14 rotates under the drive of the second motor 26, the universal ball joint 23 converts the circumferential motion into the swing motion of the suction frame 20. At the same time, the linear feed motion of the electric slide table 25 and the guiding action of the second guide rail 11 work together to enable the motion trajectory of the suction nozzle 27 to accurately fit the generatrix curve of the irregularly shaped tank. Specifically, when the electric slide table 25 starts, it drives the second guide rail 11, then the mounting frame 15, and finally the support plate 16 to slide on the hollow plate 32, realizing the longitudinal displacement adjustment of the suction frame 20 relative to the hollow plate 32. This longitudinal displacement, combined with the lateral displacement generated by the gear 14, constitutes a complete planar coordinate motion system. This support component design breaks through the limitation of single-direction adjustment, allowing the suction nozzle 27 to cover the weld area at any position within the tank cross-section, making it particularly suitable for forming irregularly shaped tanks with complex cross-sectional shapes and drastic generatrix changes.

[0048] The universal ball joint 23 features a hollow steel tube structure with a wall thickness that has undergone strength verification, reducing its weight while meeting torque transmission requirements. A locking nut is installed at the connection between the connecting block 24 and the universal ball joint 23. After the equipment undergoes model switching or position calibration, the locking nut can eliminate the ball joint clearance, improving positional stability during slag removal operations. The electric slide table 25 uses a ball screw drive, achieving a repeatability accuracy of ±0.02mm. Its effective stroke is adjustable from 200mm to 800mm, based on common tank diameters. Combined with the trajectory planning algorithm in the control system, it enables the suction nozzle 27 to automatically follow a predetermined path.

[0049] Example 8 is an explanation based on Example 2. For details, please refer to [link / reference]. Figures 1 to 8 Each end of the support plate 16 away from the hollow plate 32 is equipped with a support 12, and a detector 35 is pinned to the support 12. A torsion spring is provided between the detector 35 and the support 12.

[0050] In this embodiment, the preload of the torsion spring is precisely calculated, ensuring that the detector 35 remains tangential to the outer surface of the tank in its natural state. When the tank experiences radial runout or generatrix offset during the molding process, the probe of the detector 35 remains in contact with the tank wall and generates a corresponding angular displacement. The pin axis of the support 12 is arranged parallel to the tank's axial direction, ensuring that the swing plane of the detector 35 is perpendicular to the tank's generatrix direction, thereby accurately capturing changes in the cross-sectional profile. The detector 35 uses either a laser displacement sensor or a contact encoder, and its signal output communicates in real time with the equipment's main control system. The sampling frequency is set to 1000 times per second, sufficient to distinguish transient deformations during high-speed molding.

[0051] Specifically, the connection surface between the support plate 16 and the support 12 is machined with a waist-shaped hole, allowing for a ±15mm radial adjustment along the tank body to accommodate the testing requirements of tanks with different wall thicknesses. When the weld trajectory is detected to deviate from the preset path by more than 0.5mm, the main control system immediately triggers the compensating movement of the electric slide 25, ensuring that the following error of the suction nozzle 27 is controlled within the allowable range of the process. The fatigue life of the torsion spring has undergone 100,000 cycles of testing, and its stiffness coefficient is designed to match the mass inertia of the detector 35, ensuring that no self-excited oscillation occurs during dynamic response. The probe tip of the detector 35 is embedded with wear-resistant ceramic beads, which minimizes the risk of surface scratches in contact measurement mode. The diameter of the ceramic beads is selected as 8mm based on the common tank curvature radius, balancing measurement accuracy and passability. The bottom of the support 12 is equipped with damping pads to absorb high-frequency vibrations transmitted during the operation of the molding equipment, preventing the detection signal from being interfered with by mechanical noise.

[0052] In summary, the detector 35 is used to detect the busbar contour data of the tank and compares and analyzes the real-time acquired contour curve with the standard process model. When defects such as local depressions, protrusions, or out-of-tolerance ellipticity are detected, the system automatically generates correction commands, driving the second motor 26 and the electric slide table 25 to work together, dynamically adjusting the spatial position of the suction nozzle 27 to ensure precise synchronization between slag removal and weld trajectory.

[0053] Two sets of detectors 35 are symmetrically arranged on both sides of the tank, forming a redundant measurement network. When a single detector experiences signal abnormalities due to welding slag splashing or obstruction, the data from the other side can serve as a backup for control calculations, improving the system's reliability and continuity. An angle encoder is installed on the pin shaft of the detector 35, providing real-time feedback on the swing angle. Combined with the known installation reference height of the support 12, the instantaneous radius value of the tank surface can be accurately calculated using trigonometric functions, providing direct data support for the radial positioning of the slag removal assembly.

[0054] In the variable diameter section or transition curved surface area of ​​the irregularly shaped tank, the following swing frequency of the detector 35 forms a closed loop coupling with the rotation speed of the tank. The main control system adaptively adjusts the power output of the suction fan 10 according to the curvature change rate of the busbar. In areas with a small curvature radius, the suction negative pressure is appropriately increased to prevent welding slag from splashing outward due to centrifugal force. In areas with a gentle curvature, the power is reduced to save energy, thus achieving a dynamic balance between slag removal effect and operating economy.

[0055] Example 9 is an explanation based on Example 2. For details, please refer to [link / reference]. Figures 1 to 8An extension plate 34 is connected to one side of the mounting bracket 15. A corrugated plate 33 is provided on the second guide rail 11 and located on one side of the rack 13. A second guide rod 36 is connected to the bottom of the support plate 16. The second guide rod 36 is slidably installed inside the extension plate 34. A second spring 37 is connected between the support plate 16 and the extension plate 34. The second spring 37 is sleeved on the outer wall of the second guide rod 36. The bottom end of the second guide rod 36 is fitted with the corrugated plate 33.

[0056] In this embodiment, the upper surface of the corrugated plate 33 is machined with a wavy profile, and a wear-resistant roller is installed at the bottom end of the second guide rod 36. The outer edge of the roller is covered with a polyurethane elastic layer, which not only ensures smooth rolling contact with the surface of the corrugated plate 33, but also reduces operating noise and metal wear. When the gear 14 drives the mounting frame 15 to move along the second guide rail 11, the roller at the bottom end of the second guide rod 36 rolls along the curved trajectory of the corrugated plate 33. Under the elastic force of the second spring 37, the support plate 16 drives the suction frame 20 to produce a vertical displacement synchronized with the profile of the corrugated plate, increasing the adsorption space of the suction frame 20, thereby expanding the effective coverage of the suction nozzle 27 and improving the adaptability to the complex curved surface of the tank. This vibration effect causes the fine welding slag particles attached to the edge of the suction nozzle 27 to detach from the adhesive state, while promoting the turbulent mixing of the airflow in the suction pipe 21, preventing welding slag from depositing and clogging at the pipe bend.

[0057] Furthermore, the second spring 37 is a variable stiffness helical spring, whose compression characteristic curve is designed nonlinearly. When the support plate 16 is in a low position, it provides a large restoring force to overcome the weight of the suction frame 20, while the stiffness is appropriately reduced when it is in a high position to avoid excessive elastic force causing the roller to lose contact with the surface of the wave plate 33.

[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0059] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
