Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a processing device and a processing method for a pipeline sealing SAE flange. Background Art

[0002] In the pipeline connection system of modern industry, SAE flange is a key connection component, and its sealing performance is directly related to the operation stability and safety of the entire pipeline system. With the continuous development of industrial technology, the processing accuracy and surface quality requirements of SAE flange are becoming increasingly stringent, especially in the grinding process. Traditional grinding methods and devices have many limitations.

[0003] The traditional SAE flange grinding method often relies on manual operation of handheld grinding tools. This method is not only inefficient and difficult to meet the needs of large-scale production, but also due to the instability of manual operation, problems such as uneven pressure and inconsistent grinding paths are prone to occur during the grinding process, making it difficult to ensure the flatness and roughness of the flange surface, which seriously affects the sealing performance and service life of the flange.

[0004] In addition, a large amount of dust will be generated during the grinding process. Traditional equipment lacks effective dust reduction measures, which makes the working environment harsh. Not only does it endanger the health of operators, but the dust will also adhere to the surface of the equipment, accelerating the wear of the equipment, reducing the reliability and accuracy of the equipment, and increasing the maintenance cost and downtime of the equipment.

[0005] Moreover, these devices are usually unable to achieve multi-sided automated grinding of flanges, requiring frequent manual turning over and adjustment of processing positions, which greatly reduces production efficiency and consistency of processing quality.

[0006] Therefore, in order to overcome the above problems, there is an urgent need for a pipeline sealing SAE flange processing device and method that is efficient, high-precision, environmentally friendly and can achieve automated grinding to meet the needs of modern industry for high-quality processing of SAE flanges. Summary of the invention

[0007] The present invention is intended to provide a processing device and a processing method for a pipeline sealing SAE flange, so as to solve the problems of uneven pressure and inconsistent grinding paths that are prone to occur in the traditional SAE flange grinding process in the prior art, resulting in difficulty in ensuring the flatness and roughness of the flange surface, seriously affecting the sealing performance and service life of the flange, and a large amount of dust will be generated during the grinding process. The traditional device lacks effective dust reduction measures, resulting in a harsh working environment, which not only endangers the health of the operator, but also the dust will adhere to the surface of the equipment, accelerate the wear of the equipment, reduce the reliability and accuracy of the equipment, and increase the maintenance cost and downtime of the equipment. Moreover, these devices are usually unable to achieve multi-sided automated grinding of the flange, and require frequent manual turning and adjustment of the processing position, which greatly reduces the production efficiency and consistency of the processing quality.

[0016] Furthermore, the adsorption device includes an adsorption plate fixedly installed on one side of the gantry, and an adsorption fan is fixedly installed in the adsorption plate.

[0017] Furthermore, a processing device and a processing method for a pipeline sealing SAE flange include the following steps:

[0018] S1: Check whether all parts of the processing device are intact, ensure that the power lines of the power equipment such as the grinding motor, clamping motor and adsorption fan are connected normally, and the motors run smoothly without abnormal noise; check whether there is enough water in the water tank of the dust suppression device, and whether the dust suppression pipe, nozzle and other parts are unobstructed and unblocked; turn on the adsorption fan of the adsorption device to check whether its suction is normal;

[0019] Place the SAE flange to be processed in the middle of the clamping suction cup of the clamping device, and rotate the adjusting wheel to drive the rotation of the clamping threaded rod. The clamping threaded rod drives the clamping suction cup to clamp and fix the SAE flange, ensuring that the flange is firmly clamped on the clamping device and will not be displaced or loosened during the processing;

[0020] S2: According to the material, size, grinding accuracy and surface roughness requirements of the SAE flange, the parameters such as the grinding motor speed, grinding wheel feed speed and grinding time are set through the control system; at the same time, according to the needs of the grinding process, the telescopic length of the hydraulic rod is adjusted to change the contact pressure between the grinding wheel and the flange surface to ensure the stability and consistency of the grinding process;

[0021] S3: Start the grinding motor, and the output end of the grinding motor drives the first driven wheel and the second driven wheel to rotate through the grinding belt, so that the grinding wheel rotates at high speed; the gantry is moved to a suitable starting position through the moving device, so that the grinding wheel contacts the surface to be ground of the SAE flange;

[0022] S4: During the grinding process, the dust suppression device works synchronously. The rotation of the second driven wheel drives the reduction gear to rotate, which in turn activates a series of components of the dust suppression device. The negative pressure airbag generates negative pressure, sucks the water in the water tank into the dust suppression pipe, and sprays it on the grinding area through the horizontal pipe, telescopic vertical pipe and nozzle, which plays a role in dust reduction and cooling. At the same time, as the third connecting rod moves, the telescopic vertical pipe will be extended and retracted accordingly to ensure that the nozzle can always effectively cover the grinding area, improve the dust reduction and cooling effect. During the grinding process, the adsorption device continues to work, and the suction force generated by the adsorption fan sucks the dust and debris generated by grinding into the adsorption plate, further reducing the pollution of dust to the working environment.

[0023] S5: When all the surfaces to be polished of the SAE flange meet the predetermined processing requirements, the operation of the polishing motor, the moving device, the dust reduction device and the adsorption device is stopped, so that the polishing wheel is out of contact with the SAE flange surface, and then the clamping motor is controlled to operate according to the preset value in the control system, so that the clamping motor drives the first clamping shaft to rotate, and the rotation of the first clamping shaft drives the second clamping shaft to rotate through the clamping belt, and the rotation of the second clamping shaft causes the first bevel gear to rotate, and the first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the clamping ring at one end to rotate, so that the SAE flange is rotated through the clamping device. After the rotation is completed, S is repeated to facilitate polishing the other side and the arc surface of the SAE flange;

[0024] S6: Reversely operate the adjusting wheel of the clamping device to release the clamping of the SAE flange and remove the processed flange from the clamping device;

[0025] Clean the residual dust and debris on the device, drain the waste water in the water tank of the dust suppression device, and perform daily maintenance on the equipment to prepare for the next processing.

[0026] The beneficial effects of this technical solution are:

[0027] (1) The clamping device is stable and adaptable to flanges of various sizes, which effectively ensures the accurate and stable position of the flange during processing, greatly reducing errors and scrap caused by displacement. The high-precision multi-directional control of the mobile device combined with the flexible and accurate displacement of the gantry can achieve fine grinding of both flat and complex curved flanges, fully meeting the diverse processing demands, greatly improving the processing quality and efficiency, and effectively shortening the production cycle. The grinding device has flexible and adjustable speed, precise control of contact pressure, and dynamic adaptation of grinding position. Targeted processing is carried out according to the characteristics of different flanges to ensure excellent surface quality. In the food and pharmaceutical industries, cleanliness and quality standards are strictly adhered to, and sealing and safety performance are enhanced in the fields of petrochemicals, greatly reducing safety hazards and economic losses.

[0028] (2) The dust suppression device works seamlessly with the grinding operation, reducing energy consumption while strongly suppressing dust diffusion, significantly improving the working environment, protecting the health of operators, and significantly reducing the risk of occupational diseases. It also reduces the erosion of dust on the grinding wheel and flange, effectively extending the life cycle of equipment and products, reducing equipment maintenance costs, stabilizing the continuity and stability of the processing process, promoting steady improvement in production efficiency, and helping companies to effectively control operating costs. At the same time, the multi-layer filtration system of the adsorption device efficiently captures various types of dust particles, deeply purifies the operating area, effectively reduces environmental pollution, effectively avoids dust accumulation inside the equipment, reduces the probability of failure, and improves the reliability and stability of equipment operation, providing solid support for continuous and stable production, reducing the frequency of downtime for maintenance, and improving production efficiency.

Check the water level in the water tank 715 of the dust reduction device 7 to ensure that there is enough water for dust reduction and cooling. At the same time, check whether the dust reduction pipe 709, the nozzle 713 and other components are unobstructed and free of blockage or leakage. Turn on the adsorption fan 802 of the adsorption device 8 to check whether its suction force is normal. You can place a thin piece of paper near the adsorption port to observe whether the paper can be firmly adsorbed to preliminarily judge the suction force. Place the SAE flange 314 to be ground in the middle of the clamping suction cup 313 of the clamping device 3, and turn the adjusting wheel 311 to adjust the clamping threaded rod 31 0 rotates, driving the clamping rod 312 and the clamping suction cup 313 to clamp and fix the SAE flange 314. During the clamping process, it is necessary to pay attention to moderate force, to ensure that the flange is firmly clamped and will not be displaced or loosened during the processing, and to avoid damage to the flange caused by excessive clamping. According to the material, size and required grinding accuracy and surface roughness requirements of the SAE flange 314, through the control system, the control system can be a control platform based on PLC or industrial computer, with a friendly human-computer interaction interface, the operator can easily input various parameters to set the speed of the grinding motor 602, the feed speed of the grinding wheel 611, the grinding time and other parameters. At the same time, according to the needs of the grinding process, the telescopic length of the hydraulic rod 606 is adjusted to change the contact pressure between the grinding wheel 611 and the flange surface. For flanges that are first processed or have high surface roughness requirements, the contact pressure can be appropriately increased;For flanges with high precision requirements or thin walls, the contact pressure should be appropriately reduced to ensure the stability and consistency of the grinding process, avoid flange deformation or unqualified surface quality due to improper pressure, start the grinding motor 602, and the output end of the grinding motor 602 drives the first driven wheel 605 and the second driven wheel 610 to rotate through the grinding belt 612, so that the grinding wheel 611 rotates at high speed, and the movement of the gantry 5 is accurately controlled by the moving device 4 to move the grinding wheel 611 to a suitable starting position, so that the grinding wheel 611 is lightly in contact with the surface to be ground of the SAE flange 314 to avoid damage to the grinding wheel 611 or the flange surface due to collision. During the grinding process, the dust reduction device 7 works synchronously, and the second driven wheel 605 and the second driven wheel 610 are driven by the moving device 4 to move the grinding wheel 611 to a suitable starting position. The rotation of the impeller 610 drives the reduction gear 701 to rotate, thereby causing a series of components of the dust reduction device 7 to operate. The negative pressure airbag 708 generates negative pressure, sucks the water in the water tank 715 into the dust reduction pipe 709, and sprays it on the grinding area through the horizontal pipe 711, the telescopic vertical pipe 712 and the nozzle 713, which plays a role in dust reduction and cooling. At the same time, the adsorption device 8 continues to work, and the suction force generated by the adsorption fan 802 sucks the dust and debris generated by grinding into the adsorption plate 801, further reducing the pollution of dust to the working environment. The coordinated work of the dust reduction and adsorption devices 8 can effectively reduce the dust concentration in the working area, improve the working environment, and reduce the wear of dust on the equipment and the impact on the processing quality.

[0050] When one surface or part of the surface of the SAE flange 314 meets the predetermined processing requirements, the operation of the grinding motor 602, the moving device 4, the dust reduction device 7 and the adsorption device 8 is stopped, so that the grinding wheel 611 is out of contact with the surface of the SAE flange 314, and the clamping motor 301 is controlled by the control system to operate. The clamping motor 301 drives the first clamping shaft 303 to rotate. The rotation of the first clamping shaft 303 drives the second clamping shaft 305 to rotate through the clamping belt 304. The rotation of the second clamping shaft 305 drives the first bevel gear 306 to rotate. The first bevel gear 306 drives the second bevel gear 307 to rotate. The second bevel gear 307 drives the clamping ring 308 at one end to rotate, so that the SAE flange 314 is rotated through the clamping device 3 to adjust the processing surface of the flange. After the rotation is completed, repeat step S3 to grind the other side and the arc surface of the SAE flange 314 to ensure that each surface of the flange can achieve the required processing Precision and surface quality requirements. During the turning and multi-faceted grinding process, attention should be paid to maintaining the consistency of processing parameters to avoid unstable processing quality due to parameter changes. When all the surfaces to be ground of the SAE flange 314 meet the predetermined processing requirements, stop the operation of the grinding motor 602, the moving device 4, the dust reduction device 7 and the adsorption device 8, reverse the adjustment wheel 311 of the clamping device 3, loosen the clamping of the SAE flange 314, and carefully remove the processed flange from the clamping device 3 to avoid collision and scratches on the processed surface. Clean the residual dust and debris on the device. You can use tools such as brushes and vacuum cleaners to clean it. Drain the waste water in the water tank 715 of the dust reduction device 7, and perform daily maintenance on the equipment, such as checking the lubrication condition of each transmission component, tightening loose screws, replacing worn tools and filter components, etc., to make full preparations for the next processing and ensure the long-term stable operation of the equipment and the consistency of processing quality.
