Description

Technical Field

[0001] This utility model relates to the field of pipe fitting production technology, specifically to an automatic sorting mechanism for a pipe fitting forging production line. Background Technology

[0002] The automatic sorting mechanism of the pipe fitting forging production line is an automated system that detects and identifies the specifications and quality of pipe fitting forgings. The control system's instruction execution unit automatically sorts and transports forgings of different states (qualified / unqualified) and specifications to the corresponding areas, thereby replacing manual labor and improving production efficiency and sorting accuracy.

[0003] In existing automated sorting processes of pipe fitting forging production lines, the efficiency of detection and sorting is generally affected by surface impurities. After forging, pipe fittings are prone to the adhesion of oxide scale, metal shavings, and other impurities. Traditional mechanisms lack targeted impurity cleaning structures, allowing impurities to directly cover the pipe fitting detection area. This prevents visual and dimensional sensors from accurately identifying the appearance and dimensional parameters of the pipe fittings. This not only requires manual shutdown for impurity cleaning and interrupts the sorting process but also increases detection errors, leading to misjudgments of qualified and unqualified products, severely reducing sorting efficiency and accuracy. Furthermore, the lack of effective pipe fitting cooling structures means that the surface temperature of pipe fittings can reach hundreds of degrees Celsius immediately after forging. When high-temperature pipe fittings directly enter the sorting and detection stage, they cause continuous thermal damage to the detection components, accelerating the aging of internal circuit components and shortening the lifespan of sensors. The high-temperature environment also affects the measurement accuracy and stability of the detection components, causing fluctuations in the detection data of the same batch of pipe fittings, further reducing sorting reliability and making it difficult to meet the high-efficiency and stable sorting requirements of pipe fitting forging production.

[0019] This utility model discloses an automatic sorting mechanism for a pipe fitting forging production line.

[0020] This utility model provides, for example Figure 1-4 An automatic sorting mechanism for a pipe fitting forging production line is shown, including a base 1, support frames 2 are fixedly connected to both ends of the side wall of the base 1, a U-shaped support plate 3 is fixedly connected between the tops of the two support frames 2, a hydraulic rod 4 is fixedly connected to the top of the U-shaped support plate 3, one end of the hydraulic rod 4 passes through the top of the U-shaped support plate 3 and is fixedly connected to a support plate 5, a cooling air plate 6 is fixedly connected to the top end of the support plate 5, and a detection component 7 is fixedly connected to the bottom end of the support plate 5. An impurity adsorption plate 8 is fixedly connected between the two side walls of the U-shaped support plate 3. A protective mesh plate 9 is fixedly connected to the bottom of the impurity adsorption plate 8 through an opening. A connecting chamber 10 is fixedly connected to the top of the base 1. A sorting plate 11 is fixedly connected to the cavity of the connecting chamber 10 through a drive mechanism. A feeding platform assembly 12 is fixedly connected to the two side walls of the base 1. A negative pressure fan 13 and a cooling fan 14 are fixedly connected to the two ends of the cavity of the base 1, respectively. A control display 15 is fixedly connected to the top of the side wall of the U-shaped support plate 3. The air outlet of the cooling fan 14 is fixedly connected to the air inlet of the cooling fan plate 6. A separation mechanism is provided between the negative pressure fan 13 and the impurity adsorption plate 8. The support frame 2 is made of rectangular steel. The pipe material has a bending strength ≥200MPa to ensure the U-shaped support plate 3 is installed stably. The U-shaped support plate 3 provides the installation foundation for the hydraulic rod 4 and the impurity adsorption plate 8, while also forming a protective frame to prevent interference from external debris. The hydraulic rod 4 allows for precise adjustment of the support plate 5 height, controlling the distance between the detection component 7 and the pipe joint to 50-80mm, adapting to the detection of different pipe joint specifications. The support plate 5 is made of aluminum alloy, which is lightweight and rigid, facilitating the lifting and lowering of the hydraulic rod 4. The cooling air plate 6 sprays cooling air onto the detection area and pipe joint, quickly reducing the temperature of the pipe joint and the working environment temperature of the detection component 7. The detection component 7 achieves pipe... Automated inspection of joint dimensions and defects achieves an accuracy of ±0.02mm, replacing manual inspection and increasing efficiency by 3 times. An impurity adsorption plate 8, under negative pressure, adsorbs impurities such as oxide scale and iron filings from the pipe joint surface, achieving an impurity removal rate of ≥95% and preventing interference with inspection. A protective mesh plate 9 prevents large particles from entering the adsorption channel and causing blockage, ensuring continuous and efficient adsorption. A connecting chamber 10 provides installation space for the drive mechanism and sorting plate 11, while guiding the pipe joints into the sorting area. The sorting plate 11 separates qualified and unqualified pipe joints to different unloading platforms, achieving a sorting accuracy of ≥99%. The unloading platform assembly 12 facilitates pipe... The joints are fed in an orderly manner to avoid collision damage. The negative pressure fan 13 provides power for impurity adsorption, ensuring stable adsorption effect. The cooling fan 14 provides a continuous cooling air source for the cooling air plate 6. The control display 15 displays the detection data, sorting quantity, and equipment status in real time, which is convenient for operators to monitor. The separation mechanism separates impurities from air, which is convenient for impurity recycling and treatment. Through the coordinated design of impurity cleaning and cooling, the problem of traditional automated sorting mechanisms for pipe joint forging production lines being unable to detect impurities on the pipe joint surface due to the lack of a targeted impurity cleaning structure, and the lack of a cooling structure causing high temperature damage to the detection components, affecting the accuracy and stability of the detection, is solved. To drive the sorting plate to rotate stably and achieve precise sorting of pipe fittings, such as Figure 1 and 2As shown, the drive mechanism includes a support rod 16, a motor 17, a gear 18, and a sliding opening 19. The support rod 16 is rotatably connected inside the cavity of the connecting chamber 10, and the motor 17 is fixedly connected inside the cavity of the base 1. One end of the motor 17 and the tube wall of the support rod 16 are both fixedly connected to the gear 18, and the two ends of the gear 18 are meshed together. The surface of the connecting chamber 10 has a sliding opening 19. The surface of the sorting plate 11 is fixedly connected to the rod wall of the support rod 16 through the opening. The support rod 16 provides stable support for the sorting plate 11, and the radial runout during rotation is ≤0.05mm. The motor 17 drives the support rod 16 to rotate through the gear 18, with a transmission efficiency of ≥95%. The speed can be flexibly adjusted according to the sorting speed. The gear 18 is carburized and quenched, with a surface hardness of HRC55-60, which improves wear resistance by 40% and extends service life by 2 times. The sliding opening 19 provides room for the rotation of the sorting plate 11, avoiding collision with the connecting chamber 10 and ensuring smooth sorting. To achieve the separation of impurities from air, facilitate impurity recovery, and avoid secondary pollution, such as Figure 1 and 4 The separation mechanism includes a collection chamber 20, an inclined filter screen 21, a chip discharge port sealing cover 22, a negative pressure suction pipe 23, and a negative pressure discharge pipe 24. The collection chamber 20 is fixedly connected to the bottom side wall of the U-shaped support plate 3. The inclined filter screen 21 is fixedly connected inside the cavity of the collection chamber 20. The chip discharge port sealing cover 22 is threadedly connected to one end of the bottom of the collection chamber 20 through a threaded opening. The negative pressure suction pipe 23 and the negative pressure discharge pipe 24 are fixedly connected to the top and bottom of the collection chamber 20, respectively. One end of the negative pressure suction pipe 23 is fixedly connected to the air outlet of the impurity adsorption plate 8, and one end of the negative pressure discharge pipe 24 is connected to the negative pressure fan 13. The air inlet is fixedly connected, and the collection chamber 20 can store impurities generated during 8 hours of sorting to meet the needs of continuous production. The inclined filter screen 21 achieves efficient separation of impurities from air, with an impurity retention rate of ≥98%. The inclined structure facilitates the sliding of impurities to the chip discharge port. The chip discharge port sealing cover 22 is connected by threads for quick disassembly, reducing impurity cleaning time by 60% while ensuring the collection chamber 20 is sealed to prevent impurity leakage. The negative pressure suction pipe 23 and negative pressure discharge pipe 24 ensure stable airflow with a negative pressure loss of ≤5%, ensuring stable adsorption and separation effects. To achieve multi-dimensional inspection of pipe fittings and ensure sorting accuracy, such as Figure 2As shown, the inspection component 7 includes a vision sensor, a size sensor, and a defect detection sensor. The vision sensor (12-megapixel resolution) can capture images of the pipe joint surface and identify defects such as surface cracks and dents, with a defect recognition rate of ≥99%. The size sensor (based on laser ranging principle) can measure key dimensions such as the outer diameter and length of the pipe joint with a measurement accuracy of ±0.01mm, preventing out-of-tolerance products from flowing into the next process. The defect detection sensor (based on eddy current testing principle) can detect tiny internal defects in the pipe joint with a detection depth of ≥2mm, comprehensively ensuring the quality of the pipe joint and reducing the outflow of defective products. To ensure orderly material feeding of pipe fittings and avoid collision damage, such as Figure 1-3 The two-end unloading platform assembly 12 includes an inclined unloading platform 25. Guide plates 26 are fixedly connected to the top of both ends of the inclined unloading platform 25. Polyurethane elastic damping buffer plates 27 are fixedly connected to the surface of the inclined unloading platform 25. The inclined unloading platform 25 uses gravity to realize the automatic sliding of the pipe joint without additional power, reducing energy consumption. The guide plates 26 limit the sliding direction of the pipe joint to avoid deviation that may cause jamming or falling. The unloading smoothness rate is ≥99%. The polyurethane elastic damping buffer plates 27 can buffer the impact force of the falling pipe joint, with an impact force attenuation rate of up to 80%, avoiding scratches or deformation on the surface of the pipe joint, and improving the product qualification rate by 3%. To improve the wear resistance of the sorting plate and the cooling effect of the cooling fan plate, such as Figure 1-3 As shown, the surface of the sorting plate 11 is coated with an anti-slip and wear-resistant ceramic particle-reinforced epoxy resin coating. The cooling air plate 6 is a trapezoidal hollow plate with multiple spray holes 28 on the trapezoidal surface. The anti-slip and wear-resistant ceramic particle-reinforced epoxy resin coating makes the surface hardness of the sorting plate 11 reach HRC60 or higher, improving wear resistance by 5 times. At the same time, the coefficient of friction is ≥0.8, preventing slippage during pipe joint sorting. The trapezoidal hollow plate structure ensures that the cooling air is evenly distributed within the cooling air plate 6, avoiding insufficient local airflow. The dense arrangement of the spray holes 28 along the trapezoidal surface increases the cooling air coverage area by 60%, which can quickly reduce the pipe joint temperature from 300-500℃ to 50-80℃, while maintaining the working temperature of the detection component 7 at 20-30℃, improving the detection accuracy and stability by 90%.
