Description

Technical Field

[0001] The present invention relates to the technical field of pipe support manufacturing, and more specifically, to intelligent manufacturing equipment and technology for pipe support. Background Art

[0002] As the name suggests, a pipe support is a device used to support pipes. It is also called a pipe bracket, which refers to a structural component used to support overhead pipes. It can be divided into fixed brackets, sliding brackets, guide brackets, rolling brackets, etc. Traditional pipe support manufacturing equipment and processes have significant technical bottlenecks in handling key links such as rust removal, cleaning, and varnishing, which restricts product quality and production efficiency. The main problems of existing technologies are as follows:

[0003] Traditional equipment mostly uses a fixed frequency or single stroke vibration mode, which cannot take into account the dynamic manufacturing needs of different processing stages. Due to the single motion trajectory of existing equipment, it is unable to drive the pipeline support to produce three-dimensional dynamic displacement, and the hidden areas of complex geometric structures are difficult to be effectively processed. Traditional equipment relies on a single drive source or a simple transmission mechanism, and it is difficult to synchronously achieve multi-degree-of-freedom compound motions such as swinging, rotation, and vibration, which limits the overall improvement of the processing effect.

[0016] SS01, the multi-station processing of the pipe support parts is completed in sequence through the rust removal room, cleaning room and varnish dipping room which are isolated from each other in the box;

[0017] SS02, using a servo motor to drive the input shaft to periodically rotate intermittently and cyclically change speed.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention realizes the three-dimensional dynamic displacement of the pipeline support through the cooperation of multiple components. The swing frame drives the indexing frame to revolve, the magnetic shaft is driven by the bevel gear ring to rotate back and forth, and the electromagnet on the magnetic hanger drives the pipeline support to move back and forth. Combined with the two-axis reciprocating movement of the longitudinal excitation frame, each surface of the pipeline support, especially the hidden areas of complex geometric structures, can be fully contacted with the treatment liquid. In the rust removal stage, the 35° swing combined with the high-frequency vibration allows the rust layer to be peeled off under the action of the tangential inertia force, avoiding local stress concentration. During cleaning, the swing generates turbulent vortexes, which enhances the penetration of the cleaning liquid into the gap. During paint dipping, the swing and the rotation of the magnetic shaft allow the paint liquid to adhere evenly, avoiding uneven paint film thickness. Compared with the single motion mode of traditional equipment that leads to insufficient treatment of hidden areas, the processing comprehensiveness and product quality are significantly improved.

[0023] 2. The moving frequency and stroke of the longitudinal vibration frame in the present invention change cyclically to adapt to different processing stages. During rust removal, high-frequency short stroke impacts the rust layer and low-frequency long stroke covers the surface. During cleaning, medium and high frequencies form eddy currents to impact gaps and low frequencies induce liquid film oscillations to peel off particles. During paint dipping, low-frequency long stroke wets the surface and high-frequency short stroke eliminates bubbles and forms films. This dynamically adjusted vibration mode is essentially different from the fixed-frequency or single-stroke vibration mode of traditional equipment. It can more accurately meet the process requirements of each stage, improve processing efficiency and effects, and reduce waste of processing liquid.

[0024] 3. Through the synergistic effects of the reciprocating oscillation of the oscillating frame within 35°, the biaxial movement of the longitudinal excitation frame, and the revolution and rotation of the indexing frame, the pipe support parts produce multi-dimensional dynamic displacements such as spiral and elliptical displacements during the processing process. Experiments have shown that this composite motion can effectively improve the processing coverage of hidden areas of complex structures such as threads and grooves.

[0025] 4. The present invention integrates multi-degree-of-freedom motions of swing, rotation, excitation and electromagnetic drive, and realizes asynchronous compound motion through the precise transmission design of differential module, bevel gear ring and dual-axis drive platform. For example, the revolution of the indexing frame and the swing of the swing frame form a phase difference through the differential module to avoid the single motion trajectory. The periodic reciprocating rotation of the magnetic shaft and the micro-vibration driven by the magnetic field are superimposed to ensure the uniform adhesion of the paint liquid.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] like Figures 1 to 10 As shown, the present invention provides an intelligent manufacturing device for pipe supports, comprising a box body 1, wherein the box body 1 is provided with a rust removal chamber 101, a cleaning chamber 102 and a paint dipping chamber 103 which are isolated from each other;

[0039] It also includes a swing frame 2 and a biaxially movable hanger 3;

[0040] It also includes a dual-axis drive platform 16, which is transmission-connected to the hanger 3. A central control host 9 is installed on the side of the box body 1. The rust removal chamber 101 stores rust removal liquid, the cleaning chamber 102 stores cleaning liquid, and the paint dipping chamber 103 stores paint liquid.

[0041] In the intelligent manufacturing process of pipe supports, the entire equipment works in coordination to achieve efficient production. The dual-axis drive platform 16 and the hanger 3 are driven by the central control host 9, which can accurately control the movement of the hanger 3 in three-dimensional space, so that it can transport the pipe supports 14 to be processed to the rust removal chamber 101, the cleaning chamber 102 and the varnishing chamber 103 in sequence, ensuring that each processing link is carried out in an orderly manner.

[0042] An input shaft 4 that can rotate intermittently and cyclically change speed is installed on the hanger 3;

[0043] The transmission mechanism further comprises a suspension shaft 18 rotatably mounted on the suspension frame 3 and a servo motor 17 mounted on the suspension frame 3. The output shaft end of the servo motor 17 is connected to the suspension shaft 18 via a first synchronous toothed belt. The suspension shaft 18 is provided with a staggered sector gear 19 and a sector gear 20. Two symmetrical transmission intermittent zones are provided on the suspension shaft 18 at positions corresponding to the positions between the sector gear 19 and the sector gear 20. A high-speed gear 21 connected to the sector gear 19 and a low-speed gear 36 connected to the sector gear 20 are respectively mounted on the input shaft 4.

[0044] The central angle corresponding to the sector gear 19 is 180°, the central angle corresponding to the sector gear 20 is 120°, the central angle corresponding to the transmission intermittent zone is 30°, the radius of the sector gear 19 is 8 times the radius of the high-speed gear 21, and the radius of the sector gear 20 is 3 times the radius of the low-speed gear 36;

[0045] The servo motor 17 drives the hanging shaft 18 to rotate. The fan-shaped large gear 19 and the fan-shaped small gear 20 on the hanging shaft 18 cooperate with the high-speed gear 21 and the low-speed gear 36 on the input shaft 4. When the hanging shaft 18 rotates and the fan-shaped large gear 19 engages with the high-speed gear 21, the input shaft 4 rotates at high speed. When the fan-shaped small gear 20 engages with the low-speed gear 36, the input shaft 4 rotates at low speed. In the transmission intermittent area, the input shaft 4 stops rotating, thereby realizing periodic intermittent rotation and cyclic speed change of the input shaft 4. This speed change method can provide diversified power support for subsequent processing actions according to the requirements of different processing stages. Compared with the traditional single speed drive, it can more flexibly adapt to complex manufacturing processes and improve processing accuracy and efficiency.

[0046] A biaxial excitation platform driven by an input shaft 4 is mounted on the hanger 3. A longitudinal excitation frame 5 capable of biaxial reciprocating movement is connected to the biaxial excitation platform. The biaxial reciprocating movement frequency and movement stroke of the longitudinal excitation frame 5 vary cyclically.

[0047] The dual-axis excitation platform includes an axial excitation frame 22, a first belt shaft 23 and two first screws 24 rotatably connected to the hanger 3, a second belt shaft 25 and two second screws 26 rotatably connected to the axial excitation frame 22, and first bevel gears are installed on the first belt shaft 23 and the input shaft 4, and the two first bevel gears are orthogonally meshed.

[0048] The first belt shaft 23 is connected to a second synchronous toothed belt, and the two first screw rods 24 are both connected to the second synchronous toothed belt, and the two first screw rods 24 are both connected to the axial vibration exciting frame 22;

[0049] A synchronous shaft 27 driven by a first belt shaft 23 is rotatably mounted on the axial excitation frame 22;

[0050] A synchronization groove is fixedly provided inside the first belt shaft 23 and is open at both ends and is slidably connected to the synchronization shaft 27. The cross sections of the synchronization shaft 27 and the synchronization groove are both regular hexagonal.

[0051] The second bevel gears are mounted on both the synchronous shaft 27 and the second belt shaft 25, and the two second bevel gears are orthogonally meshed;

[0052] A third synchronous toothed belt is connected to the second belt shaft 25, and two second screw rods 26 are both connected to the third synchronous toothed belt. The two second screw rods 26 are both connected to the longitudinal vibration frame 5. A second torsion spring 28 is provided at the rotation connection between the first screw rod 24 and the hanger 3 and at the rotation connection between the second screw rod 26 and the axial vibration frame 22.

[0053] The design of the dual-axis excitation platform is ingenious. When the input shaft 4 rotates, the first bevel gear on it drives the first belt shaft 23 to rotate. The first belt shaft 23 drives the two first screws 24 through the second synchronous toothed belt, causing the axial excitation frame 22 to move axially. At the same time, the first belt shaft 23 drives the synchronous shaft 27, which drives the second belt shaft 25 through the second bevel gear. The second belt shaft 25 drives the two second screws 26 with the help of the third synchronous toothed belt, thereby driving the longitudinal excitation frame 5 to reciprocate in both axes. The frequency and travel of the above-mentioned bidirectional movement change cyclically.

[0054] Rust removal stage: The high-frequency vibration of the longitudinal excitation frame 5 quickly impacts the rust layer through a short stroke to achieve local rust stripping, and the low-frequency vibration covers a larger area through a long stroke to avoid omissions. Traditional equipment uses a single frequency, and the frequency cycle change can take into account both micro-stripping and macro-covering, thereby improving the rust removal efficiency. During rust removal, the short stroke is used for local stubborn rust spots, and the long stroke is used for overall surface cleaning. If the stroke is fixed, it cannot adapt to pipe supports 14 with different degrees of rust, which may easily lead to excessive wear or incomplete cleaning.

[0055] During the cleaning phase, the medium and high frequency motion of the longitudinal vibration frame 5 drives the cleaning fluid to form vortices, impacting the pipe gaps, and the low frequency motion induces liquid film oscillation to remove residual particles. Traditional cleaning relies on fixed pressure flushing, while the combination of vibration and fluid dynamics can reduce the amount of cleaning fluid used;

[0056] The stroke fluctuation of the longitudinal excitation frame 5 forces the pipe support 14 to deviate slightly in three-dimensional space, exposing hidden blind spots. When cleaning with a fixed stroke, complex structure pipes, such as porous supports, are prone to residual stains inside.

[0057] During the paint dipping stage, low-frequency, long-stroke excitation motion is used to allow the paint liquid to fully penetrate the surface, and high-frequency, short-stroke motion is used to eliminate bubbles and form a uniform film.

[0058] The phase difference setting of the dual-axis excitation forms an elliptical motion trajectory, ensuring that the paint liquid adheres evenly to complex structures such as grooves and threads.

[0059] The two sides of the swing frame 2 are both mounted with swing shafts 6, and both swing shafts 6 are rotatably connected to the longitudinal excitation frame 5;

[0060] The swing frame 2 is driven by the input shaft 4 and swings back and forth within 35 degrees;

[0061] The vibration device further includes a hexagonal shaft 29 rotatably connected to the axial vibration frame 22, an elastic transmission belt 30 being connected between the input shaft 4 and the hexagonal shaft 29, and an exciting shaft 31 being rotatably mounted on the longitudinal vibration frame 5. The exciting shaft 31 has a hexagonal groove fixedly provided inside with an opening at the top and slidably connected to the hexagonal shaft 29, and the cross-sections of the hexagonal groove and the hexagonal shaft 29 are both regular hexagons;

[0062] A partial bevel gear is mounted on the exciting shaft 31, and a partial bevel gear is provided on the partial bevel gear. A swing shaft 6 is mounted with a swing bevel gear in transmission connection with the partial bevel gear surface.

[0063] A first torsion spring 32 is provided at the rotation connection between the other swing shaft 6 and the longitudinal excitation frame 5 and at the rotation connection between the clamping shaft 37 and the indexing frame 7;

[0064] A traverse frame 7 is rotatably mounted on the swing frame 2, and the traverse frame 7 is transmission-connected to the input shaft 4 via a differential module;

[0065] The differential module includes a first guide shaft 33 rotatably connected to a swing shaft 6 and a second guide shaft 34 rotatably connected to the swing frame 2. Third bevel gears are mounted on both the first guide shaft 33 and the excitation shaft 31, and the two third bevel gears are orthogonally meshed. The first guide shaft 33 is connected to the second guide shaft 34 via a fourth synchronous belt. Fourth bevel gears are mounted on both the second guide shaft 34 and the indexing frame 7, and the two fourth bevel gears are meshed with each other.

[0066] The reciprocating swing of the swing frame 2 and the biaxial reciprocating movement of the longitudinal excitation frame 5 form a composite motion trajectory, forcing the pipe support 14 to produce three-dimensional dynamic displacement during rust removal and cleaning, completely exposing the surface blind spots. If the swing is eliminated, the hidden areas of the complex structure pipeline will be difficult to effectively handle. The swing frame 2 swing drives the magnetic shaft 8 to achieve periodic start-stop rotation through the bevel gear ring 10, so that the pipe support 14 can be evenly coated with paint liquid during paint dipping, and the intermittent rotation can prevent paint liquid accumulation.

[0067] During the rust removal stage, 35° swing combined with high-frequency vibration allows the rust layer to be peeled off under the action of tangential inertial force, avoiding local stress concentration caused by pure vertical vibration;

[0068] During the cleaning phase, the swing forces the pipe support 14 to generate turbulent vortices in the cleaning liquid, thereby enhancing the liquid's ability to penetrate the gaps. At the same time, the 35° range ensures that the pipe will not collide with the box 1 during the swing.

[0069] During the painting stage, the paint is evenly adhered to the surface by centrifugal force. Combined with the reciprocating rotation of the magnetic shaft 8, this prevents uneven paint film thickness caused by static painting. The centrifugal acceleration generated by the 35° swing has been optimized through simulation to dynamically match the paint viscosity. Other angles will cause paint splashing or poor adhesion.

[0070] The setting of the differential module makes the movement of the indexing frame 7 more complex and efficient. When the input shaft 4 rotates, the indexing frame 7 rotates asynchronously with the swing frame 2 through a series of transmission components such as the exciting shaft 31, the first guide shaft 33, and the second guide shaft 34. The magnetic shaft 8 on the indexing frame 7 initially has a certain preload under the action of the first torsion spring 9. The magnetic shaft 8 is driven by a rotating bevel gear meshing with the toothed portion on the bevel gear ring 10 and rotates back and forth within a set period. This rotational movement cooperates with the movement of the swing frame 2 and the indexing frame 7, so that the magnetic hanger 11 installed on the magnetic shaft 8 can continuously change its angle and position. In the cleaning process, the pipe support 14 on the magnetic hanger 11 can better drive the pipe support 14 to clean in all directions, and the cleaning liquid can be flushed to every corner, thereby improving the cleaning effect and overcoming the problem of cleaning dead corners that may exist in traditional cleaning methods.

[0071] A plurality of card shafts 37 are rotatably mounted on the indexing frame 7, and each card shaft 37 is magnetically connected to a magnetic shaft 8. A bevel gear ring 10 is mounted on the swing frame 2. The card shaft 37 is driven by the bevel gear ring 10 and reciprocates within a set period.

[0072] Multiple magnetic hangers 11 are installed on the magnetic shaft 8, and a group of positioning rods 12 and a group of vibration springs 13 are installed on the two sides of each magnetic hanger 11. Each group of positioning rods 12 is provided with a pipe support 14 that fits with the vibration spring 13. Two electromagnets 15 are built into the magnetic hanger 11. The magnetic field strength of the electromagnet 15 changes back and forth and drives the pipe support 14 to move back and forth.

[0073] The bevel gear ring 10 is provided with a set of regularly distributed toothed portions and a set of regularly distributed toothless portions. The number of the toothed portions and the toothless portions is the same. The toothed portions and the toothless portions are arranged in pairs on the bevel gear ring 10. A rotating bevel gear meshing with the toothed portions is fixedly mounted on the clamping shaft 37.

[0074] A magnetic slot 35 with one end open is fixedly provided inside the card shaft 37, and a magnetic card column that is engaged with the magnetic slot 35 is fixedly provided at the bottom of the magnetic attraction shaft 8. The cross-sections of the magnetic card column and the magnetic slot 35 are both regular hexagons.

[0075] The magnetic field strength of the electromagnet 15 on the magnetic hanger 11 changes back and forth, driving the pipe support 14 to move back and forth. During the entire processing process, the reciprocating movement of the pipe support 14 can maintain dynamic position changes during rust removal, cleaning and paint dipping, further enhancing the contact effect between the various processing fluids and the pipe support 14, ensuring the stability and consistency of the processing quality. Compared with the traditional fixed placement processing method, it significantly improves product quality and production efficiency.

[0076] The indexing frame 7 is connected to the input shaft 4 through the differential module. While the swing frame 2 swings back and forth, the indexing frame 7 rotates around the axis of the swing frame 2. Rust removal / cleaning stage: the revolution forces the pipe support 14 to move as a whole with the indexing frame 7, and cooperates with the reciprocating motion of the longitudinal excitation frame 5 to form a three-dimensional spiral trajectory to ensure that the rust layer or stains are impacted from multiple angles. Paint dipping stage: the revolution exposes the pipeline evenly to the paint liquid to avoid excessive thickness of the local paint film. The orthogonal meshing of the bevel gears of the differential module and the synchronous toothed belt drive design ensure that the revolution is asynchronous with the swing of the swing frame 2. If it is changed to the same speed transmission, the motion trajectory will be single and the cleaning coverage rate will be reduced.

[0077] The magnetic shaft 8 rotates periodically through the meshing of the teeth of the bevel gear ring 10, driving the positioning rod 12 to achieve synchronous rotation. The rotation causes the surface contact point of the pipe support 14 to continuously change, avoiding local wear caused by fixed friction. During cleaning and paint dipping, the rotating positioning rod 12 stirs the liquid to form a vortex, improving the penetration efficiency of chemical reagents or paint liquid. If the rotation and revolution are cancelled, liquid or rust residue is likely to remain in the grooves or threaded parts of the pipe.

[0078] The electromagnet 15 built into the magnetic hanger 11 drives the pipe support 14 to move back and forth at high frequency and slightly by changing the magnetic field strength, shaking off the droplets attached to the surface. The centrifugal force generated by the revolution of the indexing frame 7 and the rotation of the positioning rod 12 forces the liquid to separate from the pipe surface along the tangential direction, reducing liquid retention. The traditional process relies on gravity to drain naturally, while this design shortens the draining time through the dual action of "vibration and centrifugation";

[0079] The electromagnet 15 is driven by an alternating current controlled by the central control host 9, and the magnetic field strength increases or decreases periodically according to the set frequency;

[0080] The magnetic post at the bottom of the positioning rod 12 and the magnetic slot 35 of the magnetic shaft 8 adopt a regular hexagonal cross-section design, which mechanically restricts the pipe support 14 to move only axially and cannot rotate or shift laterally to prevent it from falling out.

[0081] The vibration springs 13 on both sides of the positioning rod 12 fit with the pipe support 14, and the spring preload provides reverse resistance, limiting the movement range of the pipe support 14 to the set stroke to avoid over-travel and disengagement. The electromagnet 15 still maintains a certain magnetic attraction when the pipe support 14 moves to the extreme position, and uses magnetic force to assist in fixing the pipe support 14 to ensure that it is always in contact with the positioning rod 12.

[0082] An intelligent manufacturing process for a pipe support comprises the following steps:

[0083] SS01, the multi-station processing of the pipe support 14 is completed in sequence through the rust removal chamber 101, the cleaning chamber 102 and the varnish dipping chamber 103 which are isolated from each other in the box body 1;

[0084] SS02, using the servo motor 17 to drive the input shaft 4 to periodically rotate intermittently and cyclically change speed. The input shaft 4 drives the longitudinal excitation frame 5 to perform biaxial reciprocating movement through the biaxial excitation platform, and the movement frequency and stroke change cyclically;

[0085] SS03 and input shaft 4 drive the swing frame 2 to swing back and forth within 35 degrees, and drive the indexing frame 7 to revolve through the differential module. The magnetic shaft 8 on the indexing frame 7 is driven by the bevel gear ring 10 to rotate back and forth periodically.

[0086] SS04, the magnetic hanger 11 on the magnetic shaft 8 drives the pipe support 14 to move back and forth through the change of the magnetic field strength of the electromagnet 15, combined with the vibration spring 13 to limit the stroke, forming a three-dimensional dynamic displacement;

[0087] SS05 and the central control host 9 coordinately control the dual-axis drive platform 16, the excitation parameters and the magnetic field strength of the electromagnet 15 to adapt to the process requirements of the rust removal, cleaning and varnishing stages.
