Description

Technical Field

[0001] This invention belongs to the field of steel pipe production technology, and specifically relates to a feeding device for a steel pipe cutting production line. Background Technology

[0002] Steel pipes are steel materials with hollow cross-sections, whose length is much greater than their diameter or circumference. According to the cross-sectional shape, they are divided into circular, square, rectangular, and irregularly shaped steel pipes. Steel pipes are not only used for transporting fluids and powdery solids, exchanging heat energy, and manufacturing mechanical parts and containers, but they are also an economical steel material. Using steel pipes to manufacture building structural space frames, columns, and mechanical supports can reduce weight and save 20-40% of metal. Moreover, it can realize factory-based mechanized construction. Using steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area to be coated with protective layer, saving investment and maintenance costs.

[0003] A feeding device for seamless steel pipe production is disclosed in existing patent publication number CN 216302286 U, which includes two symmetrically distributed side plates. The left sides of the two side plates are fixedly connected by baffles. Two symmetrically distributed drive rollers are provided between the two side plates. The drive rollers are rotatably connected to the side plates through drive shafts. The two drive rollers are connected by a conveyor belt. One end of one drive shaft passes through the inner wall of the side plate and is welded with a disc. A cam is provided on one side of the disc. The cam is rotatably connected to the side plate through a rotating shaft. Multiple arc-shaped grooves are formed in a ring shape on the surface of the disc near the edge. An inclined limiting plate is provided between the two side plates and above the conveyor belt. This device cannot preheat the steel pipe and needs some improvements.

The steel pipe feeding platform 1 is powered by an external workshop power supply to drive the internal components. The steel pipe feeding platform 1 is also equipped with an equipment program, which can control the opening and closing of the air compressor 16, the operation of the two sets of electric sliders, the opening and closing of the heating fan 27, the operation of the two sets of clamping manipulators, the operation of the two sets of spraying manipulators, the operation of the rotating chain 131, and the opening and closing of the five sets of electric valves. The air compressor 16, two sets of electric sliders, heating fan 27, two sets of clamping manipulators, two sets of spraying manipulators, five sets of electric valves, camera 14, and rotating chain 131 are all connected to the equipment program signal.

[0019] Steel pipe feeding preheating operation: During the operation of the steel pipe cutting production line, workers need to feed the steel pipes to facilitate cutting. First, workers use hoisting equipment to transport the steel pipes to the production workshop and place them on the feeding plate 15. Then, workers turn on the workshop power, at which point the steel pipe feeding platform 1 starts, and the equipment program starts. The equipment program uses camera 14 to detect the position and size of the steel pipe and compares it with the set values. The equipment program sets the steel pipe size range to X1~X2, which can be adjusted according to specific needs. The heating value range of the heating fan 27 is Y1~Y3, which can also be adjusted according to specific needs. When the equipment program detects the steel pipe size value as X1 through camera 14, the equipment program determines that the steel pipe size is too small. The equipment program then controls two sets of clamping robotic arms to start, and the two sets of clamping robotic arms respectively clamp both ends of the steel pipe and place it... On the feeding preheating platform 23, the equipment program controls the heating fan 27 to start, with a heating value of Y1. The first electric valve 281, the fourth electric valve 29, and the fifth electric valve 291 are opened, while the second electric valve 282 and the third electric valve 283 are closed. The heating fan 27 blows hot air through the first ventilation pipe 272 into the second ventilation pipe 28, and then sprays it outward from the first preheating nozzle 24 onto the surface of the steel pipe. The first preheating nozzle 24 is set at an angle, which allows the hot air to flow from one end of the steel pipe to the other. At the same time, the second ventilation pipe 28 can divert the hot air to the first heat-conducting plate 25 and the second heat-conducting plate 251, so that the two sets of heat-conducting plates directly contact the surface of the steel pipe and preheat it, reducing heat dispersion, reducing energy consumption during preheating, and improving heating efficiency. After completing the above operations, the equipment program controls the next operation.

[0020] When the equipment program detects the steel pipe's size as X2 through camera 14, it determines that the steel pipe is too large. The equipment program then controls two sets of clamping robotic arms to start, clamping both ends of the steel pipe and placing it on the feeding preheating platform 23. Then, the equipment program controls the heating fan 27 to start, with a heating value of Y2. All five electric valves are opened, and the heating fan 27 blows hot air through the first ventilation pipe 272 into the second ventilation pipe 28, and then sprays it outward from the three preheating nozzles to different positions on the steel pipe surface. This allows the hot air to directly preheat different positions on the steel pipe surface. At the same time, the second ventilation pipe 28 can divert the hot air to the first heat-conducting plate 25 and the second heat-conducting plate 251, allowing the two sets of heat-conducting plates to directly contact the steel pipe surface and preheat it, reducing heat dispersion, lowering energy consumption during preheating, and improving heating efficiency. After completing the above operations, the equipment program controls the next operation.

[0021] During the above operations, the equipment program can control the opening and closing of the first electric valve 281, the second electric valve 282, and the third electric valve 283 individually, thereby controlling the opening and closing of the first preheating nozzle 24, the second preheating nozzle 241, and the third preheating nozzle 242 individually, and can perform preheating operations on a certain area of ​​the steel pipe individually.

[0022] By using the heating fan 27, camera 14, two sets of clamping robotic arms, five sets of electric valves, and the equipment program in coordination, the preheating temperature and method can be changed according to the different sizes of the feeding steel pipes. When preheating small-sized steel pipes, a set of preheating nozzles is used for low-temperature preheating while hot air is diverted to two sets of heat-conducting plates, allowing the two sets of heat-conducting plates to directly contact the surface of the steel pipe and perform preheating operations, reducing heat dispersion, reducing energy consumption during preheating, and improving heating efficiency. When preheating large-sized steel pipes, three sets of preheating nozzles are used in conjunction with two sets of heat-conducting plates, allowing hot air to directly preheat different positions on the surface of the steel pipe, increasing the preheating speed and reducing the preheating time required.

[0023] Steel pipe feeding and coating operation: After completing the above operations, the equipment program controls the coating operation. The program stops the heating fan 27, closes the five sets of electric valves, and uses camera 14 to detect the position of the feeding preheating platform 23 and controls the two sets of electric sliders to start. The two sets of electric sliders move inward along the two sets of electric slide rails, moving the feeding preheating platform 23. When the feeding preheating platform 23 moves below the rotating chain 131, the program controls the two sets of electric sliders to stop. The program sets the pumping value range of the air compressor 16 to A1~A2, which can be adjusted according to specific needs. The coating amount range of the two sets of spraying robots is B1~B2, which can be adjusted according to specific needs. The rotation speed range of the rotating chain 131 is C1, which can be adjusted according to specific needs. When the program detects the steel pipe's dimension value as X1, it controls the air compressor... The pumping value of 16 is adjusted to A2. The air compressor 16 pumps compressed air into the two sets of first telescopic cylinders 12. The two sets of first telescopic cylinders 12 extend outward and drive the second mounting platform 13 to move downward. The second mounting platform 13 drives the rotating chain 131 to move downward, so that the coating brush 132 on the rotating chain 131 is in contact with the surface of the steel pipe. Then, the equipment program controls the two sets of spraying robots to apply the maintenance liquid to the surface of the steel pipe. The coating amount is B1. After the two sets of spraying robots finish coating, the equipment program controls the rotating chain 131 to start, with a speed of C1. Then, the equipment program controls the two sets of clamping robots to clamp the steel pipe and rotate it. During the rotation of the steel pipe, the rotating chain 131 drives the coating brush 132 to evenly brush the maintenance liquid sprayed by the two sets of spraying robots onto the surface of the steel pipe, so as to prevent the steel pipe from rusting or scratching during subsequent transportation.

[0024] When the equipment program detects that the steel pipe's size is X2, it controls the air compressor 16 to adjust its pumping value to A1. The air compressor 16 pumps compressed air into the two sets of first telescopic cylinders 12. The two sets of first telescopic cylinders 12 extend outward and drive the second mounting platform 13 to move downward. The second mounting platform 13 drives the rotating chain 131 to move downward, so that the coating brush 132 on the rotating chain 131 comes into contact with the surface of the steel pipe. Then, the equipment program controls the two sets of spraying robots to apply a maintenance liquid to the surface of the steel pipe, with a coating amount of B2. After the two sets of spraying robots finish coating, the equipment program controls the rotating chain 131 to start, with a speed of C1. Then, the equipment program controls the two sets of clamping robots to clamp the steel pipe and rotate it. During the rotation of the steel pipe, the rotating chain 131 drives the coating brush 132 to evenly brush the maintenance liquid sprayed by the two sets of spraying robots onto the surface of the steel pipe, preventing the steel pipe from rusting or scratching during subsequent transportation.

[0025] After completing the above operations, the equipment program controls the drying operation. The equipment program controls the air compressor 16 to stop, the two sets of first telescopic cylinders 12 to retract upwards and drive the second mounting platform 13 to move upwards. The second mounting platform 13 drives the rotating chain 131 to move upwards, so that the coating brush 132 on the rotating chain 131 separates from the surface of the steel pipe. Then the equipment program changes the drying method according to the different coating amounts of the two sets of spraying robots. When the equipment program detects that the coating amount of the two sets of spraying robots is B1, the equipment program controls the heating fan 27 to start, the heating value is Y3, and only controls the first electric valve 281 to open. The heating fan 27 blows hot air into the second ventilation pipe 28 through the first ventilation pipe 272, and then sprays it outwards from the first preheating nozzle 24 to the surface of the steel pipe. The first preheating nozzle 24 is set at an angle, which allows the hot air to flow along one end of the steel pipe to the other end, drying the residual maintenance liquid on the surface of the steel pipe, which is convenient for subsequent transportation and prevents the maintenance liquid from dripping everywhere and affecting the workshop production environment.

[0026] When the equipment program detects that the coating amount of the two sets of spraying robots is B2, the equipment program controls the heating fan 27 to start, the heating value is Y3, the first electric valve 281, the second electric valve 282, and the third electric valve 283 are opened, and the heating fan 27 blows hot air into the second ventilation pipe 28 through the first ventilation pipe 272, and then sprays it outward from the three sets of preheating nozzles to the surface of the steel pipe, to dry the residual maintenance liquid on the surface of the steel pipe, accelerate the drying speed of the maintenance liquid, and avoid water stains.

[0027] After completing the above operations, the equipment program will send completion information to the staff and control the two sets of gripping robotic arms to hold the steel pipe and place it on the feeding plate 15.

[0028] By using two sets of spraying robots, a rotating chain 131, coating brushes 132, and the equipment program in conjunction with the operation, the surface of the steel pipe can be cleaned and maintained after preheating. The cleaning intensity of the coating brushes 132 can be adjusted according to the size of the steel pipe, ensuring that the brushes remain in contact with the surface to prevent dust and dirt from remaining and affecting the accuracy of subsequent cutting. By using the heating fan 27, three sets of preheating nozzles, and the equipment program in conjunction with the operation, the surface of the steel pipe can be dried after coating. The air outlet method can be adjusted according to the size of the steel pipe. When the steel pipe is small, only one set of preheating nozzles is used for drying, allowing hot air to flow from one end of the steel pipe to the other, reducing heat consumption and achieving energy saving and emission reduction. When the steel pipe is large, three sets of preheating nozzles are used for drying, preventing residual maintenance liquid from dripping everywhere during subsequent feeding and affecting the workshop production environment, accelerating the drying speed of the maintenance liquid, and avoiding water stains.
