[0002] In the field of mechanical engineering, roll forming of hyperbolic plates has always been a challenging task. Traditional roll forming devices have exposed many problems in practical applications, which seriously restricts the production quality and efficiency of hyperbolic plates.

[0003] On the one hand, the adjustment of the plate forming angle is often not flexible enough. In different engineering projects, the bending angle requirements for the hyperbolic plate are different, and traditional equipment is difficult to achieve free bending, resulting in the inability to meet diverse production needs. This not only increases production costs, but may also affect the final forming quality of the plate due to inaccurate angles, resulting in an increase in product failure rates.

[0004] On the other hand, the cleanliness of the roller surface is crucial to the quality of sheet forming. However, the existing technology lacks effective detection means and cannot accurately determine whether the roller surface is clean in a timely manner, which easily leads to impurities, stains, etc. affecting the contact between the sheet and the roller, thereby causing surface defects and reducing product quality.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 6 , a double curvature plate roll bending device for mechanical engineering, such as Figure 1 As shown, it includes a molding machine 1, a detection mechanism 2 is arranged on one side of the molding machine 1, a grinding mechanism 3 is arranged on one side of the detection mechanism 2, a cleaning mechanism 4 is arranged below the detection mechanism 2, both ends of the cleaning mechanism 4 are rotatably connected to the inner wall of the molding machine 1 respectively, and an angle adjustment mechanism 5 is arranged on one side of the pressure roller of the molding machine 1, and the angle adjustment mechanism 5 includes an auxiliary roller 55.

[0025] In order to detect the surface cleanliness of the pressing roller of the forming machine 1, the detecting mechanism 2 is set to detect the surface cleanliness of the pressing roller of the forming machine 1. It can timely find out whether there are impurities, stains, etc. on the surface of the pressing roller, avoid affecting the quality of sheet metal forming due to the unclean surface of the pressing roller, ensure that the sheet metal can have good contact with the pressing roller during the roll bending process, and make the forming effect more in line with the expected standard.

[0026] In order to grind and flatten the surface of the auxiliary roller 55, the grinding mechanism 3 can grind and flatten the surface of the auxiliary roller 55, which helps to maintain the flatness and smoothness of the surface of the auxiliary roller 55, and prevents surface defects such as scratches and dents on the plate during the roller bending process due to the rough or uneven surface of the auxiliary roller 55, thereby improving the appearance quality and overall quality of the plate after forming.

[0027] In order to clean the surface of the auxiliary roller 55 and the surface of the pressing roller of the forming machine 1, the cleaning mechanism 4 is set to clean the surface of the auxiliary roller 55 and the pressing roller of the forming machine 1. On the one hand, it can reduce the adverse effects of impurity accumulation on the roller body such as corrosion and wear, and extend the service life of the roller body; on the other hand, keeping the roller body clean helps to maintain stable operation of the equipment, reduce the probability of equipment failure due to impurity interference, and ensure production continuity.

[0028] In order to realize the free bending of the plate forming angle, the angle adjustment mechanism 5 is set to realize the function of free bending of the plate forming angle, which greatly improves the flexibility and applicability of the device. The bending angle of the plate can be accurately adjusted according to different mechanical engineering needs to meet the diverse requirements of hyperbolic plate forming. There is no need to frequently change equipment or perform complicated mold adjustments, which effectively improves production efficiency.

[0029] In this embodiment, if Figure 1-Figure 3As shown, the detection mechanism 2 includes a first hydraulic cylinder 21, the upper end of the first hydraulic cylinder 21 is fixedly connected to the upper end surface of the molding machine 1, the lower end of the first hydraulic cylinder 21 is fixedly connected to a placement plate 22, one side of the placement plate 22 is slidably connected to the side of the molding machine 1, the upper surface of the placement plate 22 is fixedly connected to a first motor 23, grooves 24 are respectively provided on both sides of the molding machine 1, the inner wall of each groove 24 is respectively slidably connected to a first bearing 25, a screw rod 26 is fixedly connected between the inner rings of the two first bearings 25, the output shaft of the first motor 23 is fixedly connected to the inner ring of one of the first bearings, a screw nut of the screw rod 26 is fixedly connected to a first cylinder 27, the lower surface of the screw nut of the screw rod 26 is rotatably connected to a connecting block 28, the piston rod of the first cylinder 27 is rotatably connected to the side of the connecting block 28, and the lower end of the connecting block 28 is fixedly connected to an industrial camera 29.

[0030] Specifically, the first motor 23 drives the screw 26 to rotate, driving the screw nut and the components connected thereto to move in the horizontal direction, and then cooperates with the first cylinder 27 to adjust the angle and position of the connecting block 28, so that the industrial camera 29 can be accurately positioned in multiple dimensions such as level and angle, and can fully cover all areas of the surface of the pressing roller, ensuring that there are no blind spots in detection, greatly improving the comprehensiveness and accuracy of detection.

[0031] In this embodiment, if Figure 2 As shown, the grinding mechanism 3 includes a second hydraulic cylinder 32, one end of the second hydraulic cylinder 32 is embedded with one side of the lower end of the molding machine 1, and the other end of the second hydraulic cylinder 32 is fixedly connected to the slide plate 31, and support columns 33 are symmetrically arranged on the upper surface of the slide plate 31, and the upper ends of the two support columns 33 are rotatably connected to the grinding rollers 34, and a first gear 35 is arranged on the outer side of one of the support columns 33, and one end of the grinding roller 34 extends to one side of the support column 33, and one end of the grinding roller 34 is fixedly connected to the side of the first gear 35, and a second motor 36 is arranged on the upper surface of the slide plate 31, and one end of the output shaft of the second motor 36 is fixedly connected to the second gear 37, and the second gear 37 and the first gear 35 are transmission-connected by a toothed belt, and a pad is arranged on the lower surface of the second motor 36, and a damping shock absorber 38 is arranged in an array on the lower surface of the pad, and the lower end of the damping shock absorber 38 is embedded in the plate body of the slide plate 31.

[0032] Specifically, through the telescopic movement of the second hydraulic cylinder 32, the slide plate 31 can be pushed to reciprocate in the horizontal direction, thereby driving the grinding-related components installed thereon to move closer to or away from the auxiliary roller 55 that needs to be polished, thereby achieving coarse adjustment of the grinding position, so as to adapt to the grinding requirements of the auxiliary roller 55 in different installation positions and different working conditions; the setting of the damping shock absorber 38, on the one hand, reduces the impact of vibration on the second motor 36, avoids the second motor 36 from loosening or damage due to long-term vibration, and extends the service life of the second motor 36; on the other hand, it also makes the entire grinding mechanism 3 more stable during operation, reduces the problems of poor contact between the grinding roller 34 and the auxiliary roller 55 and reduced grinding accuracy caused by vibration, ensures efficient and high-quality grinding work, and also reduces the noise generated by vibration, thereby improving the working environment.

[0033] In this embodiment, if Figure 4-Figure 6 As shown, the cleaning mechanism 4 includes a circular groove 40, which is located on the inner side of the molding machine 1, and a second bearing 47 is embedded in the inner wall of the circular groove 40, and a connecting pipe 49 is fixedly connected to the inner ring of the second bearing 47, and an electric turntable 48 is fixedly sleeved on the outer surface of the connecting pipe 49, and the side of the electric turntable 48 is fixedly connected to the outer side of the molding machine 1, and one end of the connecting pipe 49 is fixedly connected to a sealed bearing, and the outer ring of the sealed bearing is fixedly connected to an external water pipe 410, and the other end of the connecting pipe 49 extends to the other side of the second bearing 47, and the other end of the connecting pipe 49 is fixedly connected to a rotating component 46; the rotating component 46 A water channel is provided inside, and the surface of the water channel is communicated with the inner wall of the connecting pipe 49, one end of the rotating component 46 is fixedly connected to the docking pipe 43, the inner wall of the docking pipe 43 is fixedly communicated with the water channel of the rotating component 46, the body of the docking pipe 43 is provided with a spring groove, the inner wall of the spring groove is provided with a spring 44, one end of the spring 44 is fixedly connected to the inner wall of the spring groove, the other end of the spring 44 is fixedly connected to the sealing block 45, the outer surface of one end of the docking pipe 43 is fixedly connected to the connecting pipe 41, the pipe body array of the connecting pipe 41 is provided with water outlet holes, and the outer surface of the connecting pipe 41 is fixedly sleeved with a cleaning cotton 42.

[0034] Specifically, the connecting pipe 49 is driven to rotate by means of the electric turntable 48, thereby driving the connecting pipe 41 and the cleaning cotton 42 to rotate around the corresponding axis, so that the cleaning cotton 42 can completely contact the surface of the auxiliary roller 55 or the pressing roller of the forming machine 1. The operator starts the rotating roller of the forming machine 1 and simultaneously starts the hydraulic rotating disk 53 to drive the auxiliary roller 55 to rotate. Both the circumferential surface of the roller body and the position near the end can be covered, avoiding cleaning dead corners, greatly improving the comprehensiveness and effectiveness of cleaning, and water is evenly sprayed through the water outlet of the connecting pipe 41. With the cooperation of the cleaning cotton 42, it can better remove dust, impurities, etc. on the surface of the roller body, improve the cleaning effect, ensure the cleanliness of the roller surface, and facilitate subsequent processing and production as well as the normal operation of the equipment.

[0035] In this embodiment, the door sealing block 45 is disc-shaped, and a plug is fixedly connected to the center of one side of the door sealing block 45 , and the diameter of the plug is the same as the inner diameter of the butt tube 43 .

[0036] Specifically, the sealing block 45 is disc-shaped and has a large sealing area. It can well cover the opening of one end of the butt joint 43 and play a preliminary water-stopping role. A plug is fixedly connected at the center of one side of the circle, and the diameter of the plug is the same as the inner diameter of the butt joint 43. This design allows the plug to be accurately inserted into the inside of the butt joint 43 during sealing, forming a tight fit similar to a piston, further enhancing the sealing of the plug. Compared with simply relying on the disc-shaped sealing block 45 for sealing, the presence of the plug can effectively prevent water from leaking from the gap between the port of the butt joint 43 and the sealing block 45, ensuring that in a non-clean state, water can be reliably blocked in front of the butt joint 43, achieving a good water-stopping effect, avoiding waste of water resources and the adverse effects of leakage on other parts of the equipment.

[0037] In this embodiment, if Figure 1 and Figure 2 As shown, the angle adjustment mechanism 5 includes a second cylinder 51, one end of which is fixedly connected to a third hydraulic cylinder 52, the inner wall of the molding machine 1 is symmetrically provided with slide grooves 50, the outer surface of the third hydraulic cylinder 52 is slidably connected to the inner wall of the slide groove 50 through an L-shaped slider, and the two ends of the auxiliary roller 55 are rotatably connected to bearing groups 54 respectively, the bearings in the bearing group 54 do not contact each other, the two outer rings of the bearings of the bearing group 54 are connected by an N-type connecting block, a hydraulic rotating disk 53 is arranged between the two bearings of the bearing group 54, the rotating part of the hydraulic rotating disk 53 is fixedly connected to the outer surface of one end of the auxiliary roller 55, and the two side surfaces of the hydraulic rotating disk 53 are fixedly connected to the outer rings of the two bearings of the bearing group 54 respectively.

[0038] Specifically, the angle adjustment mechanism 5 can adapt to the production needs of hyperbolic plates with different specifications and different bending angle requirements by virtue of its flexible and precise angle adjustment capability. Whether it is a relatively simple small-angle bending or a complex large-angle hyperbolic shape, it can be achieved by adjusting the angle of the auxiliary roller 55.

[0039] In this embodiment, a placement groove adapted to the screw nut of the screw 26 and the first cylinder 27 is provided at the upper end of the molding machine 1 .

[0040] Specifically, placing the screw nut and the first cylinder 27 in the placement groove at the upper end of the molding machine 1 can provide certain protection for these components and reduce the impact of external collisions on them. Some components are hidden in the placement groove, making the overall appearance of the molding machine 1 more concise and avoiding safety hazards such as bumps caused by exposed components to operators.

[0041] In this embodiment, one third of the surface of the auxiliary roller 55 is exposed to the outside of the molding machine 1 .

[0042] Specifically, at this time, the auxiliary roller 55 does not contact the surface of the cleaning cotton 42, and only contacts the surface of the grinding roller 34, and the surface of the grinding roller 34 also does not contact the surface of the cleaning cotton 42, thereby preventing the grinding roller 34 from being disturbed by the cleaning cotton 42 when grinding and leveling the auxiliary roller 55, thereby affecting the grinding effect.

[0043] Reference Figure 1-Figure 6 , the operating steps of a double curvature plate roll bending forming device used in mechanical engineering are as follows: Step 1: When the forming machine 1 is used to process the sheet, the second cylinder 51 and the third hydraulic cylinder 52 drive the auxiliary roller 55 to adjust the designated deflection angle of the sheet processing. After the positioning is completed, the hydraulic rotating disk 53 starts to drive the auxiliary roller 55 to rotate and start processing the sheet. If the sheet is unqualified after processing, the operator checks the pressing roller and the rotating roller of the forming machine 1 and the auxiliary roller 55 to further determine whether each roller needs to be repaired. If repair is required, perform step 2; Step 2: When testing, first the first hydraulic cylinder 21 is started, and the height of the placement plate 22 is adjusted as needed, so that the subsequent components are roughly in a suitable height range for testing the pressing roller. Then the first motor 23 is started, driving the screw rod 26 to rotate. The screw nut on the screw rod 26 moves laterally under the action of the screw rod 26, driving the first cylinder 27, the connecting block 28 and the industrial camera 29 connected thereto to move together in the horizontal direction to the approximate position of the target area. Then the piston rod of the first cylinder 27 is extended and retracted to change the angle and position of the connecting block 28, and further accurately adjust the position and posture of the industrial camera 29, so that the industrial camera 29 can finally accurately align with the specific part of the surface of the pressing roller that needs to be tested, take pictures to obtain image information, and thus realize the detection action of the surface cleanliness of the pressing roller and the auxiliary roller 55; Step 3, the electric turntable 48 drives the connecting pipe 49 to rotate 180 degrees, and the connecting pipe 49 drives the rotating component 46 to rotate and then drives the docking pipe 43 to rotate. At this time, the surface of the cleaning cotton 42 contacts the surfaces of the pressing roller, the rotating roller and the auxiliary roller 55 of the molding machine 1 respectively. Then the water pipe 410 is externally connected to the cleaning water, and the cleaning water flows through the inner wall of the connecting pipe 49 and the water channel of the rotating component 46 to squeeze the sealing block 45 that forms a sealing effect. The impact force on the sealing block 45 is greater than the elastic force of the spring 44. The cleaning water enters the connecting pipe 41 through the docking pipe 43 and is then sprayed out from the water outlet of the connecting pipe 41 to further wet the cleaning cotton; Step 4: After the surfaces of the pressing roller, the rotating roller and the auxiliary roller 55 are monitored in real time by the industrial camera 29 and their cleanliness meets the standard, the screw nut of the screw 26 and the first cylinder 27 are moved to one side under the rotation of the first motor 23, and are lifted into the placement groove at the upper end of the molding machine 1 by the first hydraulic cylinder 21 until the detection mechanism 2 and the cleaning mechanism 4 return to their initial state. At this time, the second cylinder 51 drives the third hydraulic cylinder 52 to move, and one-third of the surface of the auxiliary roller 55 is exposed to the outside of the molding machine 1. The second hydraulic cylinder 32 drives the slide plate 31 to approach the molding machine 1 until the surface of the grinding roller 34 is cleaned. The surface contacts the surface of the auxiliary roller 55, and the second motor 36 drives the grinding roller 34 to rotate through the gear transmission system to start grinding the auxiliary roller 55. The operator detects through the profilometer that the arithmetic mean roughness of the auxiliary roller 55 is within the preset range. At the same time, the pressing roller and the rotating roller are ground. The operator can improve the existing grinding mechanism 3 by installing an improved grinding mechanism 3 on the other side of the forming machine 1, and the support column 33 is changed to be liftable. The maximum lifting height is that the pressing roller contacts the surface of the auxiliary roller 55, so that both the pressing roller and the rotating roller can be ground and flattened by the grinding mechanism 3.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
