DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0031] Impurities contact the metal plate with the flattening roller rotating, are easy to extrude and damage the surface of the metal plate, cause harm to it, and the center line of the metal plate and the center line of the flattening roller do not coincide, which is easy to cause the metal plate to gradually deviate from the track in the flattening machine conveying process.

[0032] Please refer to Figures 1-4 The embodiment provides a sheet metal part flattening device for sheet metal machining, which comprises a rack 1, the top of the rack 1 is fixedly provided with a flattening part 2 and a driving part 3 at both ends respectively, the flattening part 2 is connected with the driving part 3, the flattening part 2 comprises a plurality of upper flattening rollers, a lifting system connected with the upper flattening rollers and lower flattening rollers, the upper flattening rollers correspond to the lower flattening rollers one by one, the lifting system drives the upper flattening rollers to move along the vertical direction, and the thickness of the metal plate can be flexibly adjusted, the driving part 3 comprises a driving motor and a plurality of gear sets, the plurality of gear sets are connected with the plurality of lower flattening rollers respectively, the driving motor drives the plurality of gear sets to rotate, and then drives the lower flattening rollers to rotate, a driving mechanism 4 for providing horizontal force is arranged at the top center of the rack 1, two output ends of the driving mechanism 4 are respectively provided with two cleaning mechanisms 5 for cleaning the impurities on the surface of the flattening part 2, the surfaces of the two cleaning mechanisms 5 are provided with collecting mechanisms 6 for collecting the impurities scraped by the cleaning mechanisms 5, and positioning mechanisms 7 for positioning the metal plate are symmetrically arranged on the two sides of the flattening part 2.

[0033] Both positioning mechanisms 7 include a first cylinder 71. The end caps of the two first cylinders 71 are fixedly connected to both sides of the flattening part 2. The output ends of the two first cylinders 71 pass through the flattening part 2 and are fixedly provided with positioning plates 72 for positioning the metal sheet.

[0034] Considering that the metal sheet moves horizontally as the upper pressure roller and lower straightening roller rotate, it is impossible to guarantee that the centerline of the metal sheet coincides with the centerlines of the upper pressure roller and lower straightening roller. This can easily cause the sheet to gradually deviate from the track during the leveling machine's conveying process, and in severe cases, it may get stuck in the roller gap, causing machine downtime or equipment damage. Therefore, if... Figure 2 As shown, by extending and retracting the two first cylinders 71, the corresponding positioning plates 72 are driven to move repeatedly and come into contact with the metal plates between the two positioning plates 72, continuously correcting the position of the metal plates so that the center line of the metal plates coincides with the center line of the upper pressure roller and the lower straightening roller, preventing the plates from gradually deviating from the track during the conveying process of the straightening machine, and in severe cases, getting stuck in the gap between the rollers, causing machine stoppage or equipment damage.

[0035] Furthermore, during use, the surfaces of the upper pressure roller and the lower leveling roller are prone to the adhesion of fine, hard impurities. These impurities, as the upper pressure roller and the lower leveling roller rotate, come into contact with the metal sheet, easily squeezing and damaging the surface of the metal sheet, causing harm. Therefore, if... Figure 2 As shown, the driving mechanism 4 generates a horizontal force, which drives the cleaning mechanism 5 to scrape along the surface of the upper pressure roller and the lower straightening roller, removing impurities from the upper pressure roller and the lower straightening roller. The cleaning mechanism 6 then collects the removed impurities, thereby preventing impurities from remaining on the upper pressure roller and the lower straightening roller and preventing impurities from damaging the surface of the metal sheet.

[0036] Based on the above, the specific structure will be disclosed in detail:

[0037] Considering the need to use cleaning mechanism 5 to clean the surfaces of multiple upper and lower pressure rollers to prevent impurities remaining on the surfaces of the rollers from damaging the metal sheet, it is necessary to disclose the specific structure of cleaning mechanism 5. Therefore, as Figure 2As shown, the cleaning mechanism 5 includes an elastic element 51, which is connected to the drive mechanism 4. A connecting plate 52 is fixedly installed at the output end of the elastic element 51. Multiple cleaning plates 53 for cleaning the flattening part 2 are fixedly installed at the bottom of the connecting plate 52. The elastic element 51 has a certain elasticity and exerts a pushing force on the cleaning plates 53, so that the cleaning plates 53 can adhere to the surfaces of the upper and lower flattening rollers. Multiple cleaning plates 53 in the two sets of cleaning plates 53 respectively contact multiple upper and lower flattening rollers. The drive mechanism 4 provides a horizontal force to drive the connecting plate 52 to move, thereby driving the cleaning plates 53 to move along the surfaces of the upper and lower flattening rollers, cleaning off the impurities attached to the surfaces of the upper and lower flattening rollers, and preventing these impurities from damaging the surface of the metal sheet when flattening the metal sheet.

[0038] To enable the drive mechanism 4 to move the cleaning plate 53 back and forth along the surfaces of the upper and lower pressure rollers to clean impurities from their surfaces, the specific structure of the drive mechanism 4 must be disclosed. Therefore, as... Figure 2 As shown, the drive mechanism 4 includes a vertical plate 41, which is fixedly installed at the top center of the frame 1. Two second cylinders 42 are symmetrically fixed at both ends of one side of the vertical plate 41. The output ends of the two second cylinders 42 are fixedly installed with connecting blocks 43 through the vertical plate 41. The bottom of the connecting block 43 is fixedly connected to the elastic member 51. By extending and retracting the first cylinder 71, the connecting block 43 is driven to move horizontally, thereby driving the elastic member 51, the connecting plate 52 and the cleaning plate 53 to move horizontally, so that the cleaning plate 53 slides and scrapes back and forth on the surfaces of the upper and lower pressure rollers.

[0039] To enable the collecting mechanism 6 to absorb and collect the impurities scraped off the surfaces of the upper and lower pressure rollers by the cleaning plate 53, the specific structure of the collecting mechanism 6 must be disclosed. Therefore, as Figure 4 As shown, the collection mechanism 6 includes multiple pairs of straight pipes 61, which are interspersed on the top of the connecting plate 52. Each pair of straight pipes 61 is respectively located on both sides of the corresponding cleaning plate 53. The bottom end of each straight pipe 61 is fixedly connected to an air nozzle 62. Through the air nozzle 62 and the straight pipe 61, the impurities scraped off the surface of the upper and lower pressure rollers by the cleaning plate 53 are absorbed, preventing the impurities from splashing after being scraped off.

[0040] To enable the collecting mechanism 6 to gather impurities from the air mixed with impurities drawn in by the nozzle 62 for subsequent cleaning, the specific structure of the collecting mechanism 6 needs to be further disclosed. Therefore, as... Figure 3As shown, the bottom ends of multiple pairs of straight pipes 61 are fixedly connected to the same U-shaped conduit 63. A flexible pipe 64 is fixedly connected to the surface of the U-shaped conduit 63. Through the U-shaped conduit 63 and the flexible pipe 64, the air containing impurities absorbed by multiple air nozzles 62 and straight pipes 61 is collected together for subsequent cleaning of impurities in the air.

[0041] To ensure that the collecting mechanism 6 can effectively remove impurities from the air containing impurities absorbed by the air nozzle 62, and to prevent impurities from clogging the collecting mechanism 6, the specific structure of the collecting mechanism 6 must be further disclosed. Therefore, such as Figure 3 As shown, one end of the flexible tube 64 is fixedly connected to the equipment box 65. The bottom of the equipment box 65 is fixedly mounted on the connecting block 43. Filter screens 66 are fixedly installed inside the two equipment boxes 65. Air containing impurities that flows through the flexible tube 64 enters the equipment box 65 through the filter screen 66 and the equipment box 65. The impurities are filtered out by the filter screen 66, and the clean air leaves the equipment box 65, thereby completing the removal of impurities and preventing impurities from clogging the collection mechanism 6.

[0042] To ensure that the air containing impurities flows smoothly through the nozzle 62, straight pipe 61, U-shaped duct 63, and flexible pipe 64 into the equipment box 65, and then exits from the equipment box 65 to complete the impurity collection, the specific structure of the collection mechanism 6 must be further disclosed. Therefore, as... Figure 2 As shown, the collection mechanism 6 also includes an air pump 67. The bottom of the air pump 67 is also fixedly mounted on the connecting block 43. The input end of the air pump 67 is fixedly connected to the inside of the equipment box 65. When the air pump 67 is running, it generates power to draw air containing impurities into the straight pipe 61 through the air nozzle 62, and then flows through the U-shaped conduit 63 and the flexible pipe 64 into the equipment box 65. The impurities are filtered out by the filter screen 66, and the clean air continues to leave the equipment box 65, enters the air pump 67, and is discharged from the output end of the air pump 67, thereby completing the entire process of collecting impurities.

[0043] In summary, the working principle of this solution is as follows:

[0044] When the flattening device is needed to straighten the metal sheet, the metal sheet is inserted between the upper flattening roller and the lower flattening roller, and the drive unit 3 is started to drive the upper flattening roller and the lower flattening roller to rotate, so as to flatten the metal sheet.

[0045] Two first cylinders 71 are activated, and the two first cylinders 71 extend and retract, driving the corresponding positioning plates 72 to move repeatedly and contact the metal plates between the two positioning plates 72, continuously correcting the position of the metal plates.

[0046] Restart the first cylinder 71. The first cylinder 71 extends and retracts, driving the connecting block 43 to move horizontally, which in turn drives the elastic element 51, the connecting plate 52, and the cleaning plate 53 to move horizontally. This causes the cleaning plate 53 to slide and scrape back and forth on the surfaces of the upper and lower pressure rollers. Then start the air pump 67. The air pump 67 operates and generates power, drawing air containing impurities into the straight pipe 61 through the air nozzle 62. The air then flows through the U-shaped conduit 63 and the flexible pipe 64 into the equipment box 65. The impurities are filtered out by the filter screen 66, and the clean air continues to leave the equipment box 65, enters the air pump 67, and is discharged from the output end of the air pump 67.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
